SECTION 1 – BLENDER STARTUP 

Getting Started – Read this page! 

THE NEXT 13 PAGES OF THIS MANUAL WILL GUIDE YOU, STEP BY STEP, TO A 

SUCCESSFUL STARTUP. 

IT WON'T TAKE LONG; SO.... PLEASE, DON'T SKIP AHEAD. 

HERE ARE THE STEPS YOU WILL FOLLOW: 

Page 4 SAFETY HAZARDS………………………….. TWO HAZARDS exist on this unit: MIX BLADES and SLIDE VALVES. 

Read this short sensible page so no one gets hurt. 

Page 6 ASSEMBLY INSTRUCTIONS………………. Very little assembly is required. But you might as well get it right the first 

time. ALSO: Pay attention to the section on WIRING. 

Page 11 CHECK OUT PROCEDURE………………. This is to see if you did it right. It also will tell if anything was damaged 

in shipping. 

Page 15 LOAD CELL CALIBRATION……………… We already did this. But shipping or rough handling during assembly 

sometimes creates load cell problems. If weight readings are not 

correct, you MUST recalibrate the load cells. 

Page 16 SETUP OUTPUTS & MATERIAL TYPES... To "TURN ON" a component, it must be designated as to TYPE, either 

REGRIND, NATURAL, or ADDITIVE. Each is handled differently by the 

MATH routines. The controller MUST know the material TYPE to know 

what the setting means. This is IMPORTANT. Be SURE you 

UNDERSTAND this section before trying to operate your system. 

Page 19 RATE CALIBRATION……………………… This is NOT really necessary. But if your system uses non-standard 

equipment, you MAY want to do this. 

Page 20 SETTINGS and NORMAL OPERATION… From this point forward, operating your system is a snap. This section 

tells you just how simple it is and exactly what to expect under normal 

operating conditions. 

Page 22 SPECIAL FEATURES……………………... Your system can do much more then you may know. This page reviews 

briefly some of the added features that are available to you and where in 

this manual you can find them.

Assembly and Installation Instructions 

CAUTION: LOAD CELLS ARE EASILY DAMAGED. 

If the FRAME is dropped from TWO FEET, the load cells WILL BE DAMAGED. 

THE WARRANTY DOES NOT COVER DAMAGED LOAD CELLS. 

The following items have been shipped to you: 

1. FRAME and HOPPER assembly: (bolted to skid) 

2. CONTROLLER BOX: with the instruction manual. 

3. FEEDER BOX: contains a COLOR or ADDITIVE feeder: optional. 

4. FLOW CONTROL ASSEMBLY: optional 

5. FLOOR STAND or VACUUM TAKEOFF ASSEMBLY: optional 

RED INSTRUCTION STICKERS will assist you during assembly. 

LIFT HANGERS are available to allow lifting the blender with a strap or chain. Contact Maguire 

if you require them. 

1A. If your unit is to be MACHINE mounted: 

For WSB MB, 100, 200, and 400 series models: 

Two ways to do this are suggested ON THE NEXT PAGE: 

The LEFT diagram shows the FRAME and SLIDE GATE both drilled with the proper bolt pattern for 

your machine and THROUGH BOLTED to your press. 

The RIGHT diagram shows only the 10 x 10 steel slide-gate plate drilled for your bolt pattern and 

bolted to your press. The FRAME is then bolted to it using the existing 8 x 8 inch bolt pattern holes 

and bolts provided. With this method, bolt head clearance holes are required in the poly-pro slide gate 

plate. This mounting works well on smaller machines. 

For WSB 900 and 1800 series models: 

An additional machine mount adaptor plate may be required. If you have ANY DOUBT about the 

STABILITY of the unit when bolted directly to your machine throat, please call us for advice. 

NOTE: When choosing proper orientation, be sure to retain access to the 

controller and weigh chamber, clearance for hinged doors, and access to 

removable feeder hoppers. 

1B. If your unit is STAND mounted: 

A stand is provided and your unit will bolt directly to it. An assembly DIAGRAM is provided on the 

following pages. 

An air operated FLOW CONTROL ASSEMBLY is provided for dispensing into a container. The 

purpose of this unit is to allow time for mixing to occur after each dispense. This flow valve keeps the 

mix chamber full to just below the sensor. This assembly bolts directly to the bottom of the Weigh 

Scale Blender frame.

2. Slide the WEIGH BIN into position. It rests behind the clear-hinged access 

window. Install with the air cylinder toward you. If bin is already in place, remove any 

shipping materials, packing tape or string. 

3. Hang the Color and Additive Feeders: (Optional) 

a. Lift side latches and fully extend slide assembly. Remove the hopper. Leave slide 

extended. 

b. Tilting the entire slide assembly, motor end up, insert one corner of hanger cross bar 

behind frame corner post. 

c. Rotate assembly into place so both ends of cross bar are behind corner posts. 

d. Lower into place, bottom edge resting on frame and cross bar properly positioned behind 

corner posts. 

e. Re-install hopper. Slide motor forward until latches engage. 

4. Place the controller on the support tray and plug in all cords: 

a. Air solenoid 8 or 14 pin plug into the matching receptacle. 

b. Auger feeder drive motors into duplex receptacle. 

c. Mixer motor into right side of controller. 

d. Sensor cord plug into right side of controller. 

e. Load Cell plug into port on left side of controller. 

5. Plug the CONTROLLER into the receptacle located under the controller tray. 

IMPORTANT: Do NOT plug the controller into a separate 

power source. The controller ground path MUST be the 

same as the blender frame ground path. If your system has 

the controller located in a remote location, MAKE CERTAIN 

that the power to the controller comes from the receptacle 

mounted on the Blender frame. 

6. Plug the power cord coming from this box into a 110-volt power source (220 

volt outside USA). This cord MUST provide the ONLY power source for the entire 

system, including the controller. See: WIRING CONSIDERATIONS, next page. 1800 

series blenders also require a 240-volt power source for the mix motors. 

7. Connect Compressed Air to the unit. About 80 psi (5.5 bar) is recommended (40 

psi for the Micro Blender). Lubricated air is NOT recommended. 

NOTE: Micro Blenders should be set to 40 psi (2.7 bar). The 

Vertical Valves used in removable hoppers on Micro 

Blenders, 100, and 200 series blenders are more accurate at 

the lower 40 psi pressure setting. 

8. Remove all protective paper from the plastic windows. 




Wiring Considerations 

The wiring of your blender is very important to its proper operation. Electronics are very 

susceptible to voltage spikes and static charges, both of which are very common in plastics 

factories. To MINIMIZE these things, consider the following. 

‣ The power supply should be solid; a strong supply, not limited by a "just adequate" 

control transformer. A source of voltage that comes from a large transformer that 

supplies a large portion of the plant is better then a small power supply transformer that 

is intended to supply only this device. Power supplies, even though they may be 

"isolation" transformers, will still pass all voltage spikes right through. Their small size 

limits their ability to dampen RF (Radio Frequency) noise that is often induced into the 

system from outside sources. This proves worse then connection to larger central 

transformers. 

‣ Avoid running the power supply line along side any heavy power lines. An unshielded power 

supply in a raceway along side other heavy power lines will pick up induced RF noise and 

transfer it into the WSB steel enclosure causing computer trouble. 

‣ Long extension cords should be avoided. They also reduce the ability to provide a dampening 

effect on spikes and static. The further the equipment is from a substantial power source, the 

more susceptible it is to spikes. 

‣ The CONTROLLER and the WSB frame MUST share the same GROUND PATH. This is why 

you MUST plug the controller into the OUTLET that is provided ON THE FRAME. 

‣ REMOTE SYSTEMS. If you have your controller mounted in a remote location, you will have a 

number of power and signal cords running between the frame and the controller. BE SURE that 

the LOW VOLTAGE lines are NOT BUNDLED to the HIGH VOLTAGE lines and keep them 

away from other nearby electrical lines. 

LOW VOLTAGE lines are: Load Cell cable, Level Sensor cord, 

Air Solenoid cable, and Printer and Computer cables. 

HIGH VOLTAGE lines are: Mixer motor cable, Feeder motors, 

and MAIN POWER line. 

Keep these sets of cables SEPARATED. 

‣ VACUUM LOADER CONVEYING LINES. Keep them away from all electrical lines, particularly 

the Load Cell lines. Conveying plastic produces extreme static sources. A power supply line, 

even in conduit, that runs next to a vacuum line, can introduce extreme static pulses into the 

processor. Keep conveying lines SEPARATED from electrical supply lines. 

‣ We use many internal tooth "STAR" washers in assembling the WSB to ensure good ground 

between painted parts. Do not remove them. 

PROCEED TO: CHECK OUT PROCEDURE NEXT PAGE 




Check Out Procedure 

As you go through this procedure, if WHAT SHOULD HAPPEN, doesn't happen, see next section, 

DIAGNOSTICS, for what to check. 

100/200 series models (3K load cells), display all weights in 1/10 grams (xxxx.x). 

400/900/1800 series models (10K load cells) display weights in FULL grams, NO decimal 

point (xxxxx). 

On this page we show all weights with NO decimal point. 

Start with NO MATERIAL in any hoppers. 

Be sure an AIR SUPPLY is connected. 

Place ALL switches DOWN; POWER (on front); STOP and PAUSE (on left). 

PROCEDURE: 

WHAT SHOULD HAPPEN: 

1. POWER UP CONTROLLER 

PLUG IN CONTROLLER 

Nothing should happen. 

Air pressure should be holding ALL valves CLOSED. 

This means all air cylinders are extended. If any slide gate or flap is 

open, air lines are reversed. 

If a FLOW CONTROL VALVE is installed, check it. 

TURN POWER ON Display should say ( TWELVE ), 

Followed by version date (V=xxxxxT) 

Followed by the check sum number (CKS=xxxx) 

Followed by (ROM OK ) 

Followed by (RAM = 8K) 

Followed by model number (MODEL220) or the model you have: 

(MB, 140, 14R, 220, 240, 24R, 420, 440,44R, 940, 184) 

Followed by ( 0), then the actual weight of material in the bin. 

This number should be zero, plus or minus several grams ( 20) to (- 

20). 

AT THIS POINT 

TOUCH WEIGH BIN VERY LIGHTLY 

Be sure the model number that was displayed matches your blender 

model number (first digit only). If this is not the case see two sections 

ahead, SELECTING CORRECT MODEL. 

Display should update the weight every second reflecting the light 

pressure that you are exerting on the bin.

SECTION 2 - OPERATION 

Load Cell Calibration 

Displays shown here are in full grams. MB, 100 and 200 series models are in 1/10 grams, 

with a decimal. 

If your load cells already display a weight close to zero, plus or minus 10 grams, you may skip this section and go 

directly to: 

TURNING ON OUTPUTS (next page). 

If your unit DOES NOT display an acceptable weight, you should recalibrate them, that is reset your ZERO weight, 

at this time. 

To do so: 

BE SURE 

BE SURE 

BE SURE 

BE SURE 

BE SURE 

the weigh bin is EMPTY. 

the load cell plug is plugged into the side of the controller. 

the weigh bin is resting on the load cells freely. 

the air line to the dump valve is connected as it would be during normal operation. A disconnected 

air line adds weight. 

The load cells and bin are not jammed in any way. To test for this see that a light touch on the bin 

causes the display to change. When the pressure is removed the display must return to exactly 

where it was, plus or minus 1 gram. 

If this does not happen, something is touching something and the bin is not entirely free to move. 

Check EVERYTHING around the bin. 

LOAD CELL CALIBRATION: 

The sequence of keystrokes is as follows: 

Load Cell Zero Calibration Keypad Sequence: 

Press 


Press Display will say: (P x) 

Press 

Display will say: (CAL OFF) 

Press 

Display will say: (CAL WSB) 

Press * again for LIW CAL (later versions) 


Press Display will say: (-- WAIT --) 

Followed by: (P 0) 

Press Display will say: ( x) 

The ZERO point of the load cells is now set properly. FULL weight calibration may also be done at this time, 

however, it probably is NOT NECESSARY. When load cell readings shift due to rough handling, the entire range 

of readings from ZERO to FULL shift together. The ZERO weight calibration routine resets the full range of the 

cells and, therefore, corrects FULL weight readings as well. For information on FULL weight calibration, see 

RECALIBRATION OF LOAD CELLS. 

PROCEED TO: 

TURNING ON OUTPUTS 

and MATERIAL TYPES 

NEXT PAGE 




Turning on Material Type Outputs 

This controller can control up to TWELVE (12) components; 1 through 9 and A, B, and C. 

You must "TURN ON" the COMPONENT outputs that you are going to use. Components that are TURNED OFF are not part 

of ANY routines. A component becomes TURNED ON when it is set to a MATERIAL TYPE. 

Material Type Definitions 

Material TYPES are REGRIND, NATURAL, and ADDITIVE. 

The WEIGH SCALE BLENDER handles each TYPE DIFFERENTLY. Settings have different meanings for each TYPE. 

To enter SETTINGS correctly, you MUST UNDERSTAND how different materials are handled based on their TYPE. 

So PLEASE read this page CAREFULLY. 

Material TYPES are explained here. 

How to set them is explained on the next page. 

REGRIND 

(PERCENT OF MIX) 

Components designated REGRIND will be added as a PERCENT of the ENTIRE MIX of material. For example, If component 

1 is designated as REGRIND and is set for 20.0 percent, then for every 100 pounds of blend, 20 pounds will be this 

component. 

NATURAL 

(RATIO TO EACH OTHER) 

Components designated NATURAL will be added in the proportion that you specify them to each other. Their actual 

percentage of the mix will depend on how much Regrind is specified and how much Additive is specified. For example, if 

components 2 and 3 are both designated NATURAL and are set for 10 and 40 respectively, then the RATIO of component 2 to 

component 3 will always be 10 to 40 or 1 to 4. 

If no Regrind or Additives are specified, the mix will be: 

Component 2, NATURAL, SET= 10, 20.0 percent of mix, 

Component 3, NATURAL, SET= 40, 80.0 percent of mix. 

The RATIO of 1 to 4 is maintained. 

If component 1 is specified as REGRIND at 20 percent, the mix is then 

ADDITIVE 

Component 1, REGRIND, SET= 20, 20 percent of mix, 

Component 2, NATURAL, SET= 10, 16.0 percent of mix, 

Component 3, NATURAL, SET= 40, 64.0 percent of mix. 

Components 2 and 3 are still held at a 1 to 4 ratio. 

(PERCENT OF ALL NATURALS) 

Components designated ADDITIVE will be added as a percentage of all the NATURALS added together. For example: If 

component 5 is an ADDITIVE at 5 percent, then the above example now looks like this: 

Component 1, REGRIND, SET= 20, 20 percent, 

Component 2, NATURAL, SET= 10, 15.2 percent, 

Component 3, NATURAL, SET= 40, 61.0 percent, 

Component 4, ADDITIVE, SET= 05.0, 3.8 percent. 

The REGRIND is still 20 percent of the MIX. 

The NATURALS are still at a RATIO of 1 to 4, although they have been reduced to make room for the Additive. 

The ADDITIVE is 5 percent of the NATURALS added together (5% of 76.2). 

WHY do we do it this way? Because this is how most plastic processors think of these components. REGRIND is generally 

only added when available, and then as a limited percentage of the entire mix. 

NATURALS are generally blended at a RATIO to one another. ADDITIVES are most often only intended to be added to the 

entire NATURAL portion of the mix, because regrind generally already contains these additives. 




ON THE OTHER HAND: 

If you prefer to think of your mix as a RATIO OF WEIGHTS, for example, components 1, 2, 3, 4, and 5 are to be mixed at 100, 

50, 5, 20 and 7 pounds respectively, then you may wish to specify ALL components as NATURALS. In this way these weights 

may be entered just as listed here. Components will be dispensed to maintain each at the proper specified RATIO to the other 

components. 

If you wish to think of all components as PERCENTAGES of THE MIX, percents that always add up to 100 specify ALL 

components as REGRIND and enter the exact percent for each. When ALL components are REGRINDS, ALL settings must 

add up to 99 or 100 percent. If they do not, an error message (REG >100) or (REG



Examples of Making Settings 

Below are listed 4 different examples for possible settings users can make with the make with the Maguire blender. 

Example 1: 

Blender: 

WSB 100 Series with 1000g Batch 

Materials: 30 Regrind 

% 

70 Natural 

% 

3% Color 

Application: 

Regrind is recycled next to the machine and therefore already colored. Color only needs to be added 

to the Natural Material 

Settings: Regrind R 30 

Natural N No setting required in 4 software 

N 100 in 12 software 

Color A 3 

Calculation: 

• 30% Regrind is 300g or 30 parts in the 100 parts available 

• 70% Natural and 3% Color are 73 parts in the remaining 70 parts available 

• Therefore 70 / 73 = 0.9589; 70 x 0.9589 = 67.1 parts; 3 x 0.9589 = 2.9 parts 

• The blender is doing this calculation automatically for you! 

Result: 1 Regrind 300.0g 30.0 parts 

2 Natural 671.2g 67.1 parts 

3 Color 28.8g 2.9 parts 

Batch Total 1000g 100 parts 

Example 2: 

Blender: 


Materials: 30 Regrind 

% 

70 Natural 

% 

3% Color 

Application: 

Regrind is purchased without any Color and therefore requires to be colored. Therefore Color needs 

to be added to both the Regrind and Natural materials. 

Settings: Regrind R 30 + activate *69 to treat Regrind as a Natural 

N 30 in 12 Software 



Color A 3 

Calculation: • 70% virgin, 30% regrind and 3% Color are 103 parts of 100 parts available 

• 100 / 103 = 0.97; 70 x 0.97 = 67.9 parts; 30 x 0.97; 3 x 0.9589 = 2.9 parts 









Example 3: 

Blender: 


Materials: 25% Regrind 

65% Natural 

4% Color 

6% Additive 

Application: 

Due to previous systems you are used to set all components as proportion. 

The total should be always 100%. 

Settings: Regrind R 25 + activate *69 to treat Regrind as a Natural 

R 25 in 12 software 



Color A 4 + activate *72 in 4 software 

R 4 with 12 software 

Additive A 6 + activate *71 in 4 software 

R 6 with 12 software 

Calculation: 

The blender is calculating only the set values in grams according the setting referring to the Batch 

weight. 



3 Color 60g 6.0 parts 

4 Additive 40g 4.0 parts 


Example 4: 

Blender: 


Materials: 20% Regrind 

50% Natural 

30% Natural 

4% Color 

6% Additive 

Application: 

Regrind is recycled next to the machine and therefore already has Color and Additive. Color and 

Additive only needs to be added to the 2 Natural materials. (Not possible to use 4 Software) 

Settings: Regrind R 20 

Natural N 50 

Natural N 30 

Color A 4 

Color A 6 

Calculation: 

• 20% Regrind is 200g or 20 parts in the 100 parts available 

• 50% Natural 1, 30% Natural 2, 4% Color and 6% Additive are 90 parts in the remaining 80 parts 

• Therefore 80 / 90 = 0.89; 50 x 0.89 = 44.5 parts; 30 x 0.89 = 26.7 parts; 4 x 0.89 = 3.6 parts; 6 x 

0.89 = 5.3 parts; 






5 Additive 53.3g 5.3 parts 





Materials Rate Calibration 

YOU DO NOT HAVE TO DO THIS. 

Software is set to expect STANDARD hardware. If a device meters at a much lower feed rate then expected, the software will 

take 10 to 20 cycles to fully adjust. During this time cycles will take longer. 

An example of this is a system using a 1/2" auger instead of 1". 

If you don't mind letting the system SELF ADJUST, or your hardware is STANDARD, then: 

PROCEED TO: ENTERING SETTINGS NEXT PAGE 

To perform a RATE CALIBRATION: 

Have the HOPPER LOADED with enough material to run for several cycles without running out.

Special Instructions for Selected Models 

This section relates SPECIAL information about a few selected models. 

MICRO PULSE 

Micro Pulse valves are available on models: 

WSB MB 

with optional VERTICAL VALVE MICRO PULSE valves. 

WSB 122 / WSB 140m2 with optional SLIDE GATE MICRO PULSE valves. 

WSB 131 / WSB 140m1 with optional SLIDE GATE MICRO PULSE valves. 

WSB 140Rm1 / WSB 140Rm2 with optional VERTICAL VALVE MICRO PULSE valves. 



These models may use our "MICRO PULSE" metering system for Color and Additive components. 

PULSED OUTPUT parameters control the on/off timing, or pulsing, of the valves. The controlling 

parameters are the "_PO" component parameters. 

When set to 00000, normal slide gate operation occurs. When set to a value, such as 03030, power will 

pulse ON then OFF, at 30 interrupt time intervals each way. This ON/OFF cycling will repeat for the 

entire dispense time. 

When using a MICRO PULSE valve, you must set the related _PO parameter to 03030. 

If overall blender throughput is too low, you may increase the metering rate of each Micro Pulse device 

by adjusting the cylinder airflow control valves for higher flow rate. This causes more rapid movement 

of the cylinder, ejecting more pellets per pulse. The drawback is noisy operation. 

We recommend air flow be adjusted for quiet operation, but assuring full valve movement per on/off 

cycle. We have already done this. No further adjustment should be necessary. 

The approximate correct airflow adjustments are: 

At nose of cylinder, 1.5 full turns out from full closed. 

At rear of cylinder, 2.5 full turns out from full closed. 

MICRO BLENDER slant valves, adjust by sound. 

On fixed hoppers with horizontal micro pulse valves, CLEAN OUT of the hopper can be accomplished 

by opening the "clean out" port provided under the valve. Turn to one side to allow material to drain. 

MICRO PULSE - ACCURACY 

All MICRO PULSE valves are more accurate if the associated PT parameter is set to 00090. Read PT 

parameter in the PARAMETER section. 

PROCEED TO: NORMAL OPERATION NEXT PAGE 




Instructions for Normal Operation 

Operation is very simple. 

1. Fill HOPPERS. 

2. Turn POWER ON. Verify correct settings. 

3. On Controller, set STOP and PAUSE switches UP. Turn MIXER motor switch DOWN to run for a 

timed period. 

Unit will now operate automatically to maintain a level of material high enough to cover the 

sensor. 

Use the STOP or PAUSE switches to stop the blender. 

Turn POWER off only on final shutdown. 

After several days of proper operation: 

Save all parameter information to the EEPROM for future retrieval just in case software problems 

develop later.

Normal Operating Sequence - Each Cycle 

As the sensor is uncovered, the cycle begins. The target weight of a complete batch is 18000, 9000, 4000, 2000, 1000, or 400 

grams. 

REGRINDS are dispensed first, in their order of size, largest dispense first. After all the Regrind dispenses, the space 

remaining in the weigh bin is determined. 

NATURALS are dispensed second, in their order of size, each at the correct ratio to the others. These dispenses are 

calculated to fill the bin leaving just enough space for the Additive dispenses. After all Natural dispense are complete the 

exact weight of all of the NATURALS is determined and, based on this actual dispense weight, the Additive dispenses are now 

calculated. 

ADDITIVES are dispensed last. These dispenses are calculated as a percentage of all the NATURAL components only. 

If any dispense fails to reach the requested weight, the process does NOT CONTINUE. The ALARM Strobe light flashes, the 

Beeper sounds, and the system continues to retry the dispense until the problem is remedied. 

The total batch is then dropped into the mixing chamber for blending before entering the throat of the process machine.

Controller: Controls and Outputs 

1. POWER ON switch 

Controls all power to the controller and all outputs. When power is switched off, battery backed-up RAM preserves all 

internal totals and parameters. All other functions are reset for normal start-up when power is restored. 

2. STOP END OF CYCLE / CONTINUE switch 

This is the switch that you should use to STOP the system. This switch is wired in series with the level sensor. 

Turning it off breaks the signal to the computer the same as covering the level sensor with material. This stops the 

process at the end of a full cycle. 

3. IMMEDIATE PAUSE / CONTINUE switch 

Causes a computer-controlled immediate pause during a cycle. Dispenses will stop in mid-dispense if necessary. 

When switched back to CONTINUE, the process continues without any error in amounts dispensed. 

4. ALL AIR SOLENOID outputs 

There is a single 8 pin or 14 pin (or 17 pin) Amphanol plug located on the front of the control panel. this provides 

output of all 120 volt (or 24 volt) signals to drive the air solenoids. These power sources are transistor driven and are 

protected by the 1/2 amp panel fuse. See the wiring diagram section for the correct wiring to each pin. 

If more then 7 outputs are to be driven, a 14 pin connector is provided with outputs for components 8, 9, A, B, and C. 

If 24-volt solenoids are used, a 17 pin connector is provided. 

5. POWER OUTPUTS (receptacles on panel front) 

Each outlet puts out 120 volts (240 outside USA) through internal plug- in solid state relays rated and fused at 3 

amps. These relay outputs are designed to drive motors or other devices requiring power up to 3 amps each. The 

LEFT outlet is for component number 5, and the RIGHT outlet is for component number 6. 

6. EIGHT CHARACTER DISPLAY 

Displays the accumulated total bin weight, in grams, after each dispense. The display flashes when an inadequate 

dispense has occurred and the dispense is going to be retried. Other information displayed here includes material 

usage totals, internal parameters, component types and settings and various information prompts to assist the 

operator. 

###### Numbers displayed are the total weight of material, in grams, in the bin at any time. The weight in

Password is displayed when you press the "*" key from the normal mode. 

Enter "11111" for MANUAL mode or "22222" for PROGRAM mode - or 

Enter your own password number if you have established one. 

This is displayed when you press the "*" key from the PROGRAM mode. 

Enter a 2-digit instruction number for special tasks. 

SETTING, OPERATE, TIMED, and CALIBRATE are displayed when the respective keys are pressed from the manual or 

program modes. These displays are followed by pressing a device key; 1 through 9, A, B, C, DUMP, ALARM, MIX, or HOLD. 

The word FLASHING on the display means that retries are occurring because the first dispense was not enough. Other error 

conditions also cause flashing. 




ROM OK/ROM BAD indicates the condition of ROM chip. See KEYPAD, *25, for explanation. 

7. LED LIGHTS 

The LED lights in two rows of eight located above the 8-character display indicate the following: 

LEFT COLUMN from top: 

RIGHT COLUMN from top: 

1 to 8 - Component 1 through 8 is operating. 

9 to 12 - Component 9, A, B, or C is operating. 

13 - Weigh bin dump valve operating. 

14 - Mixer motor drive relay operating. 

15 - Mixer flow control valve is open. 

16 - Alarm output operating. 

NOTE: The silk screening label on the panel front 

next to the LED’s is correct for FOUR software but 

not for TWELVE software. 

8. STROBE LIGHT AND BEEPER ALARMS 

The Strobe light flashes and the Beeper sounds when a component fails to meter properly. Alarms begin after a 

number of retries have occurred, this number determined by the parameter table (see Parameters, _AL). These 

alarms can also indicate an out-of-range TARE weight. This range is set by the TL and TH parameters; above 100 or 

below -50 grams. 

9. ALARM SILENCE 

This button stops the STROBE and BEEPER ALARMS. The continuation of the cycle to its proper completion will 

also stop the alarm. When in the BATCH mode, this button also serves to start the next batch. 

10. LEVEL SENSOR input 

The high level sensor in the mixing chamber plugs into this outlet and signals the controller to start a dispense cycle 

when it is uncovered. The sensor must be uncovered for at least 2 seconds before a cycle will start (see DLY 00488 

Parameter). Once a dispense cycle is started, covering the sensor does not stop it. Operation continues until the 

cycle is complete. 

11. MIXER MOTOR OUTLET 

This outlet is energized continuously when the MIXER SWITCH is ON (up). In the TIMED position, it stays energized 

for a time period following the dump of the weigh bin. You may adjust this time in the parameter table (MIX 03015). 

This time should be just long enough to provide adequate mixing. Mixing for a longer period may contribute to a 

static problem. Also, excessive mixing sometimes causes separation of pellets of different size and weight. 

12. MIXER MOTOR ON/OFF/TIMED SWITCH 

The Mixer ON/OFF/TIMED switch is provided as an additional safety so that you may switch the mixer off when you 

wish to clean out the mix chamber. In the UP position (ON), the mixer runs continuously. In the middle position 

(OFF) the mixer is off. In the down position, the mixer will run for a timed period following the dump of the weigh bin. 

The TIMED position is generally the correct choice. 

13. MIXER MOTOR FUSE - 3 amp 

This fuse is rated at 3 amps and protects the mixer motor circuit separately from all other fuses. On 100, 200, and 

400 series models, this fuse protects the mix motor directly. On 900 and 1800 series models, this circuit operates a 

25 amp solid-state relay in a separate box. The mix motor is protected by a "motor starter" switch with a "heater". 

This switch must be on for the motor to operate. 




14. LOAD CELL input port 

On systems with two load cells the leads are joined by a common connector that is plugged into this port. 

15. PRINTER output 

This is a parallel printer port. A printer plugged in here allows four types of information to be ported directly to a 

printer giving the benefit of a permanent printed record. They are: 

1 

. 

2 

. 

3 

. 

4 

. 

The totals of the material usage data. (press VIEW and "*" keys or use the PRT parameter to AUTOMATICALLY 

and periodically print these totals.) 

A listing of the internal parameter table. (press *77 in the PROGRAM mode.) 

A printout of information after each cycle including actual dispensed weights and percentages for every cycle. 

(press *54 in the PROGRAM mode, use "*" to set printer flag ON.) 

A printout of information after the TIME or CALIBRATE routines. (*54 flag must be on) 

Any DOS compatible parallel printer that accepts ASCII characters and does not require a Windows driver may be 

used. Connect using a standard parallel printer connecting cable, (34 pin parallel connector to a DB25 IBM 

compatible connector), available from us or at any computer store. 

16. COMPUTER input / output 

If you choose to gather material usage data automatically and continuously by computer, then this connector allows 

for connection to any IBM PC type computer operating under MS-DOS or WINDOWS. 

The COMPUTER port is a DB9 (9 pin) male port. You will need a specially wired cable from us to connect to the 

serial output on your standard PC computer. Your computer operating system must be MS-DOS or WINDOWS. 

You will need software from us for communicating with your Weigh Scale Blender or you may write your own 

software using the MLAN Protocol. Our software, The Gravimetric gateway Software (G2) allows downloading 

settings and retrieval of information and will produce reports for those customers who wish to take advantage of this 

feature. One or many Weigh Scale Blenders can be connected to one computer. For multiple Weigh Scale Blender 

systems, or communication over long distances, an additional piece of hardware is required. All WSB controllers are 

fully programmed to communicate with your computer now or at a later date. For more information, request our “G2” 

software. Additionally you may write your own communication software by using the MLAN Protocol to send 

commands to the WSB controllers. For more information on the MLAN Protocol, read the MLAN Protocol Manual. 

The G2 Software and the MLAN Protocol Manual as well as other important documents are available on our website, 

www.maguire.com. 

17. PANEL FUSE for duplex receptacle - 3 amp 

Fuses the common power wire of the duplex receptacle (the color and additive outputs). Since these outlets are only 

turned on one at a time, each is protected to the full 3 amp rating of the fuse. 

18. PANEL FUSE for processor - 1/2 amp 

Fuses power to the circuit board power supply which includes all solenoid outputs and solid-state relay outputs. 

19. INTERNAL FUSES 

An in-line fuse is provided internally to protect the main 120-volt power cord supply (10) amps. If this fuses blow, an 

internal short circuit is indicated and we don't recommend that you try to fix it. Remember, this unit carries a five-year 

warranty; just send it back. 

The MIX MOTOR timed power source and the AUGER FEEDER OUTLETS are driven by internal solid-state plug-in 

relays. These relays are located on the circuit board mounted on the inside back surface of the controller enclosure. 

A small 5-amp glass fuse is located to the right of each relay. A spare fuse is also located on the board if 

replacement is necessary. 

20. THUMBWHEEL SWITCHES 

The three sets of THUMBWHEEL switches have no effect unless they are assigned to a particular output device. 

Entry of all SETTINGS is done by using the KEYPAD. However, if you prefer, you may assign up to three 

components to the Thumbwheel switches and then use these switches to set and alter their settings. Since only three 

switch sets are available, only 3 components can be controlled in this manner. All others must use the keypad. See 

ENTERING SETTINGS for more information on how to do this.

Controller Keypad – Description of Functions 

Three (3) operation Modes are available; AUTOMATIC, MANUAL, PROGRAM. 

KEYPAD - AUTOMATIC OPERATION MODE 

This is the NORMAL operating mode. When power is turned on, the unit is in this mode. 

Automatic dispensing occurs ONLY in this mode. The AUTOMATIC mode is indicated by the 

ABSENCE of the letter "P" or "M" at the left end of the display. 

Only the VIEW, RECIPE, BATCH, FAST, TAG, CE, EXIT and SET keys are available in this 

mode: 

These keys operate only BETWEEN cycles or when the PAUSE switch is on. 

To stop between cycles, use the "STOP END OF CYCLE" switch. 

VIEW DATA 

Press to display the CURRENT Date and Time, LAST CLEARED date and time, and stored material usage 

data. Total CYCLES and Material totals are available: (in Pounds, Kilos, Grams, or Ounces) 

Number of CYCLES that have occurred: (D = #####) 

TOTAL weight of each component (X): (X = #####) 

(only active components are displayed) 

Total weight of ALL materials: (T = #####) 

Each successive press of the VIEW key displays the next total. The last displayed line will say 

(00=CLEAR) for 5 seconds. During this time, you may press 0,0 to clear the data. Waiting 5 seconds or 

pressing any other key will exit the sequence. When the sequence is exited, normal automatic operation 

resumes. These totals may be displayed as pounds, grams, kilograms, or ounces by a selection procedure 

explained later (*89). 

Press the VIEW key once followed by the "*" key to cause all information to be sent to the printer (if 

available). To then clear the data, press 00 within 5 seconds. Press any other key or, wait 5 seconds, to 

continue the process without clearing the totals. 

RECIPE 

This key allows you to GET, LOAD, and SAVE RECIPES. To SAVE a recipe you must be in the 

PROGRAM mode. Recipes are thumbwheel switch settings. 50 recipes may be stored, numbered 00 to 

50. 

This key is NOT FUNCTIONAL unless the third digit in the "FLG" parameter is set to 1 (FLG xx1xx). To do 

this, see the MAINTENANCE section, PARAMETER TABLE, "FLG". 

Assuming a proper FLG parameter is set: In normal Automatic mode: Press RCP key. If a RECIPE is 

currently in use then display will flash through the current stored data: 

(RCP --), (1R= xx ), (2N= xx.x), etc., (CE=CLEAR) 

Press CE to CLEAR CURRENT RECIPE and return settings to those previously set. 

Then press RCP to look at another recipe. Display = (GET --). 

If no RECIPE is currently in use, display says (GET --). 

Enter 2 digits to retrieve one of 50 recipes. 

Display will flash through this recipe data: 

(RCP 01), (1R= xx ), (2N= xx.x), etc., (* = LOAD) 

Press "*" to LOAD this recipe into memory. 

Routine will exit automatically. 

Press RCP or EXIT to return to the display (GET --). 

Press RCP or EXIT again to exit. 

To SAVE a RECIPE you must be in the PROGRAM mode. If you press RCP key again after display of 

(GET --), display says (SAVE --). Enter 2 digits, display will say (SAVING ). The current settings are 

saved into memory under the recipe number you have entered. Routine will EXIT automatically. 

EXIT will exit at any time. To clear a recipe, set all component settings to zero and save these settings into 

the recipe location. 




BATCH 

This key allows you to blend a PRE-SELECTED WEIGHT of material, and then STOP running and sound 

the ALARM. The process may also be programmed to sound the alarm but continue running. Since each 

cycle will always blend a full weigh bin amount, the total amount blended may exceed the target batch 

weight by up to one cycle's blend weight. 

This key is NOT FUNCTIONAL unless the last digit in the "FLG" parameter is set to 1 or 2. (xxxx1 or 

xxxx2). To do this, see the MAINTENANCE section, PARAMETER TABLE, "FLG". 

The ALARM SILENCE button on the side of the controller, is the ONLY way to CONTINUE OPERATION 

after a BATCH amount has been run. 

Assuming a proper "FLG" parameter is set: 

Press the BTCH key once to view the desired BATCH WEIGHT. 

Display will say (BW #####). 

BATCH WEIGHT is the amount you wish to dispense before stopping and/or sounding the alarm. 

Press again to view the CURRENT PORTION, of the batch, that has been dispensed. 

Display will say (CP #####). 

CURRENT PORTION shows how much of the Batch Weight you have blended so far. 

Press again to view the ACCUMULATED TOTAL weight of all batches dispensed. 

Display will say (AT #####). 

ACCUMULATED TOTAL is the sum weight of all batches that have been blended. This number will 

continue to grow until it is manually cleared to zero, or it exceeds its maximum possible value. 

Press again to view the total BATCH COUNT. 

Display will say (BC #####). 

BATCH COUNT is the total number of batches that have run. 

This number will continue to grow until it is manually cleared to zero, or it exceeds its maximum possible 

value. 

Press again to return to normal operation. 

When any of the above totals are being displayed, you may press the CE key to RESET that number to 

zero. While all four totals can be cleared to zero manually, only the BATCH WEIGHT number can be 

entered manually. 

When the BATCH WEIGHT is being displayed, you may enter a NEW batch weight using the keypad. You 

must enter a 5-digit number with leading zeros, if necessary. Maximum number that can be entered is 

"59999". 

The unit of weight that will be used is either POUNDS or KILOGRAMS as determined by the *89 option, 

explained later. 

While in operation, when the total is reached, the system will alarm and stop blending if the FLG parameter 

is set to 00001. The system will alarm but CONTINUE running if the FLG parameter is set to 00002. Use 

the ALARM SILENCE button (on the side of the controller) to silence the alarm. Pressing the BTCH key to 

view the information will also silence the alarm. 

If the system is programmed to STOP at the end of a batch, the ALARM SILENCE button MUST be 

pressed to start blending the next batch. The First press of the ALARM SILENCE button will silence the 

alarm. The Second press will start the next batch. 

NOTE: Fractional cycles are not blended. Total weight may be in over the 

target by as much as one cycle weight. 

The EXIT key will exit the BTCH sequence at any point but will NOT cause the system to start a new batch. 

If an additional 120-volt output is desired for an alarm, substitute a 4 or 7 for the 00001. 4 turns on the 

Additive outlet, 7 turns on component 7 output. 

If you have a printer connected, totals will print automatically. (See VIEW, * for details). 




FAST 

This key will allow you to exceed the normal blending rate of your unit. Once your system has learned 

proper flow rates of each material, the timing of each component dispense is very consistent cycle to cycle. 

The FAST key allows one or more FAST REPEAT cycles to follow a normal calibrated cycle. In a FAST 

REPEAT cycle all components are dispensed simultaneously, without any weights being taken. Errors in 

dispense amounts will not be detected. These are, in fact, volumetric dispenses, not gravimetric. These 

dispenses take much less time. Throughput is easily doubled in this manner. 

This key is NOT FUNCTIONAL unless the 4th digit of the "FLG" parameter is set to 1 (xxx1x). To do this, 

see the SOFTWARE MAINTENANCE section, PARAMETER TABLE, "FLG". 

The shorter mixing time may be a problem. So the number of FAST REPEAT cycles is kept as low as 

possible. Up to 4 repeats may occur. 

Press the FAST key to toggle the FAST flag ON of OFF. When set to (FAST OFF) the FAST mode will not 

operate. When set to (FAST ON) every normal calibrated dispense will be followed by up to 4 FAST 

repeat dispenses. 

This series of 4 dispenses is terminated as soon as the sensor is covered, which indicates the blender has 

"caught up". The next cycle will then be a weighed cycle, followed by the required series of fast cycles to 

catch up again. 

Press to toggle between (FAST ON) and (FAST OFF). 

Press EXIT, to exit. 

When the FAST mode is in operation, the display ( FAST) will flash intermittently. 

SETTING 

Press once and the current setting of component 1 is displayed. Display will say (1 X xx.x). X is material 

type, either R, (REGRIND); N, (NATURAL); or A, (ADDITIVE). xx.x is the current setting. 

Press SET to step forward through all the settings. 

Press * key to backup in the list. 

NEW settings may be entered directly. 

REGRIND and ADDITIVE settings are expressed as percents, up to 99.9 percent. NATURAL is any 

number you wish (usually weight). It is used to establish RATIOS with all other NATURAL entries. When 

only one material is designated as a NATURAL, the value of it's setting has no meaning, except that it must 

be set to some value to operate. 

If you wish to restrict the entry of settings to the PROGRAM mode only, (password required), you may do 

so by altering the _SE parameter for each component that you wish to "lock out". See MAINTENANCE 

SECTION, PARAMETERS, _SE parameter. 

TAG 

This key allows two pieces of information to be "tagged" onto all data that is either printed or retrieved 

through the computer port. The items are WORK ORDER number and OPERATOR number. 

This key is NOT FUNCTIONAL unless the 2nd digit of the "FLG" parameter is set to 1 (x1xxx). To do this, 

see the SOFTWARE MAINTENANCE section, PARAMETER TABLE, "FLG". 

Press once to display the current Work Order number (WO-----). Press again to display the current 

Operator number (OPRTR---). Press again for the Recipe (RECP ---). You may enter or change the Work 

Order or Operator number, when each is displayed, but not the recipe number. 

These numbers are for your TRACKING of information ONLY. They have NO EFFECT on the operation of 

the Weigh Scale Blender. 

• WORK ORDER number (6 digits) allows you to tag all information with an internal accounting 

number such as a job or purchase order number. 

• OPERATOR number (3 digits) allows you to track who is operating the equipment. 

• RECIPE number (3 digits) allows you to track what recipe you are using but you cannot enter or 

change it here. The number will be a 2-digit number if a recipe is being run that resides in the 

controller RAM; one that was entered using the RECIPE key. If a recipe has been entered using 

our MLAN software, through the computer port, then a 3-digit number will be displayed. In either 

case, the number in this field will be displayed and "tagged" to all printouts and retrievals. EXIT 

will exit the sequence at any point. 




EXIT 

This key is operational in ALL MODES. 

Use the EXIT key to exit any and all keypad sequences. 

CE 

Press "CE" at any time to display raw data readout of the load cells for five seconds. This is helpful in 

diagnosing possible load cell problems and is explained in detail in the MAINTENANCE section. 

"CE" is used frequently in connection with other keys, to clear or scan through selections. 

KEYPAD - MANUAL MODE 

CONTINUE 

STOP 

END OF CYCLE 

CONTINUE 

IMMEDIATE 

PAUSE 

In this mode, you may operate individual functions manually for test purposes. No totals are saved and 

automatic operation does not take place. The low level sensor has no control or effect over manual 

operation requests. 

The Row of keys marked OPER, TIME, VER, and CAL operate in this mode coupled with all device keys; 

1 through 9, A, B, C, DUMP, MIX, HOLD, and ALRM. 

You can enter this mode only when the controller is between cycles. The sensor must be covered or the 

STOP switch must be in the "STOP –END OF CYCLE" position. When in this mode, no automatic 

dispensing occurs. 

To enter this mode, press "*", then enter the correct password number. The password supplied with the 

unit is "11111." You may change this to any other 5 digit number, if you wish, as explained later (*45). 

When in the MANUAL mode, the letter "M" shows at the left end of display. 

The following manual functions are available in the MANUAL mode: 

OPERATE 

Press once followed by one of 16 keys: 1 through 9, A, B, C, DUMP, ALRM, MIX, or HOLD. The selected 

output operates until the key is pressed again or another output is selected. Only 1 output will be active at 

a time. EXIT will exit the sequence and close all outputs. 

TIMED 

CALIBRATE 

Press once followed by one of 12 component keys. A time in interrupts is requested; (TIME ---). Three 

digits must be entered specifying a dispense time up to 999 interrupts (about 4 seconds maximum.) CE 

will cancel entry before last digit is entered. Following a full 3-digit time entry, the specified output is 

activated for the time requested. After the dispense is weighed, the dump valve automatically operates to 

empty the weigh bin. If a printer is on line and the Print flag is ON, then output information will be printed. 

EXIT will exit the sequence. 

(RATE) Press once followed by one of the 12 component keys. 

A dispense will occur for 2 seconds. If the amount dispensed is less then 50 grams, a second dispense 

will occur for 20 seconds. Using the resulting weight and time, the processor calculates a proper 

beginning point dump rate for the start of production blending. After each dispense is weighed, the weigh 

bin dump valve automatically operates to empty the weigh bin. If a printer is on line and the Print flag is 

ON (see KEYPAD *54), then output information will be printed. EXIT will exit the sequence. 

If the display says (DO AGAIN), press any key to cause the process to repeat itself. If the display then 

says ( NO GOOD), the dispense weight was below 2 grams, not enough for a valid calibration. 

During initial operation, after each power up, the blender calibrates itself completely automatically, 

regardless of how far off the initial flow rate may be. This may take several cycles. During normal 

operation, calibration correction occurs continuously. 

Since this unit adjusts flow rates automatically, manual Rate Calibration is not necessary for proper 

operation. 




ZERO WT 

Zero Weight Calibration 

If you are collecting totals from the blender with software, a Zero Weight and Full Weight 

calibration should be done periodically, approx every 6 months, to assure accurate data in 

your totals reports. 

For this key to function, you must first set the weight calibration flag ON. 

Press *99 to observe flag status. Press * to toggle flag ON or OFF. With flag set ON, press EXIT. Poweroff 

always resets this flag to OFF. 

Press the ZERO key once to set the displayed gram weight of the empty bin to zero. BE SURE the load 

cells are plugged into the controller. Be sure the bin is properly in place and EMPTY when this key is 

pressed. 

Since the bin, even when empty, weighs about 1300 grams; it is necessary on initial setup of equipment to 

instruct the controller of the exact tare weight of the empty bin. Slight drift in the tare or zero weight 

during day-to-day operation is normal. All weight calculations automatically compensate for this drift. 

However, when the bin is empty, if the weight displayed is more than 50 grams above or below zero, then 

you may wish to reset the electronics to display zero when the bin is empty. 

If, when the bin is empty, the weight displayed is greater than 100, or less than -50, (Parameters TH and 

TL), the dispense cycle will not begin. Instead, the dump valve will repeatedly try to dump any material it 

thinks is in the bin or will sound the alarm if weight is below -50. If the load cell calibrations have drifted 

this far, it is absolutely necessary to reset empty bin weight to zero. These minimum and maximum tare 

weights are set by the TL and TH parameters. See PARAMETERS, TL and TH for more info. 

Allow system to be on for at least 5 minutes to allow for warm up of certain components before setting 

ZERO or FULL weights. 

Generally, when zero weight shifts, the full weight reading shifts the same amount. For this reason, 

resetting the ZERO WT automatically shifts the FULL WT readout by the same amount. Resetting the 

ZERO weight usually is all that is necessary to also calibrate the FULL weight. 

FULL WT 

ZERO WT. must be entered before FULL WT. to achieve proper calibration. The FULL WT. key will not 

function until you have set ZERO WT. as described above. 

If you wish to reset the controller for proper full-weight scale display, use any known weight as close to full 

bin weight as possible. Do not exceed 9999 grams. Place this weight in the bin and press the FULL WT. 

key. The display will show five dashes (FUL-----). Now enter the actual weight in grams of the item you 

are weighing. 

AGAIN, both FULL WT. and ZERO WT. have been set at the factory. A drift of several grams from these 

settings is normal and should not be of any concern. Recalibration should be considered only if ZERO is 

more than 20 grams off or FULL WT. is more than 50 grams off. These errors do not prevent proper 

proportions from being dispensed. ZERO error is always "tared" for proper weighing of each component. 

FULL scale error will only cause accumulated totals to be off by the degree of this error. The primary 

function of the WEIGH SCALE BLENDER is to dispense materials in the proper ratios. Because all 

components are weighed by the same load cells, the accuracy of these ratios is not affected by zero or full 

scale errors. 

STAR FUNCTIONS available in the MANUAL mode: 

Press (*,0,0) to CLEAR ALL DATA fields. These are the material usage totals that are viewed with the 

VIEW key. If you are tracking material usage, you should record these numbers periodically but clearing 

these totals is entirely optional and not necessary. 

After VIEWING the data or printing of data using the VIEW,* key sequence, a display of (00=CLEAR) will 

appear for 5 seconds. During this 5 seconds you may reset all data fields to zero by pressing 00. 

Pressing any other key or waiting 5 seconds will exit this sequence without clearing data. 

Press (*,9,9) to set flag to enable Weight Calibration of the Load Cells. In later model controllers you can 

specify WSB CAL or LIW CAL. Power On will always set this flag to OFF. This flag must be ON before 

the load cell weight calibration keys, ZERO and FULL WT, will function. With ON flag displayed, press 

EXIT. 




KEYPAD - PROGRAM MODE 

In this mode, you may perform ALL of the functions available in MANUAL mode, plus additional functions that alter the logic 

with which the controller operates. The PARA key operates in this mode. STAR FUNCTIONS are available by pressing the "*" 

key and two numbers. 

Just as with the MANUAL mode, you can enter this mode only when the controller is between cycles. The sensor must be 

covered or the STOP switch must be in the "STOP - END OF CYCLE" position. In the MANUAL mode, no automatic 

dispensing will occur. 

To enter this mode, press "*", then enter the correct password number. The correct password supplied with the unit is "22222". 

To change this to another 5-digit number of your choice, see (*78). When in the PROGRAM mode, the letter "P" shows at the 

left end of the display. 

The following PROGRAM functions are available in the PROGRAM mode. 

PARAMETERS: 

Press the PARA key to display the table of operating parameters that reside in memory. 

There are 13 separate groups of parameters. The first group is the GENERAL group and 

contains 20 GENERAL parameters. The other 12 groups are the COMPONENT groups and 

contain 13 COMPONENT parameters each.

Star Functions 

Star Functions are only available in PROGRAM mode: 

EXTRUDER MODE - Extrusion and Yield Control, and Rate display. 

Press (*,0,2) to turn on Extrusion or Yield control. 

The default display is ( OFF). 

Press * to toggle this flag to ( RATE ), (EXT CTRL), or (YLD CTRL). 

If you are using our EXTRUSION or YIELD control software to control your extruder, refer to our 

EXTRUSION CONTROL instruction booklet for complete information. 

If you simply want to view throughput continuously on the blender display, set this option to ( RATE ). 

This will alter the display only. In all other respects, the blender will operate normally. 

YLD-X – Extruder Control 

YLD-T – Takeoff 

YLD-D – Dual 

INPUT FORMAT - 4 Digit Entry of Settings – xx.xx 

Press (*,0,3) to allow four digit entry of settings in the format (xx.xx). This does not make the 

blender more accurate. It does allow easier setup for customers that have a mixture of setting 

requirements that is x.xx entry requirements as well as the standard xx.x requirements. 

Normally the XT parameter would be manually adjusted to allow the decimal shift. If this fourdigit 

entry option is turned on, then all entries are in the format xx.xx. The software uses only 

the first three digits unless the first digit is a zero, in which case the last three digits are selected 

and the related XT parameter is set to 00010. See XT parameter for more information. Display 

will say (INPUT FORMAT 3 Digit (XX.X) or 4 Digit (XX.XX). Use key to toggle. 

4 Software Configurations 

Press (*,0,4) to select from 4 standard software configurations. If you want your unit to look and act like 

it is running FOUR software, then this option will do this for you in one easy step. 

Use the "*" key to toggle through all selections: 

Select ( KEYPAD ) to exit without changing anything. 

Select ( R,N,C,A) for system to operate like FOUR software. 

Select ( N,N,C,A) to operate like FOUR software with the "TWO NATURALS" flag on. 

Select ( N,N,N,A) to operate with three Naturals and an additive. 

Select ( R,N,N,A) to operate with Regrind, two Naturals, and an additive. 

Component 2 is ALWAYS a NATURAL, and is never assigned a thumbwheel switch. Components 1, 3, 

and 4 are always assigned to thumbwheel switches. 

If ( R,N,C,A) is selected, component 2 is the ONLY natural and is set to 100. 

If ( N,N,C,A), ( N,N,N,A), or (R,N,N,A) is selected, the first, third, and forth components are assigned to 

switches 3, 1, and 2 respectively. Component 2 setting will be adjusted automatically at the start of each 

cycle to a number that will make all natural settings add up to 1000. In this way each NATURAL setting 

will represent a percent of the total natural blend. 

If the sum of natural settings exceeds 1000, component 2 will be set to 000, and the other naturals will be 

ratioed to each other. 

The TY and CS parameters are the ones that are altered. TY sets TYPE to Regrind, Natural or Additive. 

CS assigns the thumbwheel swatches. If CS = 40000 the software knows to calculate a setting based on 

the other naturals such that all settings total 1000. 

On 140, 240, 440 and 940 models: 

If (R,N,C,A) is selected, PARAMETERS are set: 

(1TY = REG) (2TY = NAT) (3TY = ADD) (4TY = ADD) 

(1CS 30000) (2CS 00100) (3CS 10000) (4CS 20000) 




If (N,N,C,A); same as above except: 

(1TY = NAT) (2CS 40000) 

If (N,N,N,A); same as the first except: 

(1TY = NAT) (2CS 40000) (3TY = NAT) 

If (R,N,N,A); same as the first except: 

(2CS 40000) (3TY = NAT) 

On 220 and 420 models: 

Changes are the same as above except components 6 and 5 are altered instead of components 3 and 4. 

If (R,N,C,A) is selected, PARAMETERS are set: 

(1TY = REG) (2TY = NAT) (6TY = ADD) (5TY = ADD) 

(1CS 30000) (2CS 00100) (6CS 10000) (5CS 20000) 

If (N,N,C,A); same as above except: 

(1TY = NAT) (2CS 40000) 

If (N,N,N,A); same as the first except: 

(1TY = NAT) (2CS 40000) (6TY = NAT) 

If (R,N,N,A); same as the first except: 

(2CS 40000) (6TY = NAT) 

All other TYPE parameters are set to (_TY = OFF). 

CLEAR DATA PROMPT - Prevent Totals being Cleared 

Press ( ,0,5) to inhibit the (00=CLEAR) display at the end of the VIEW sequence. 

Customers using MLAN or G2 software for retrieval of material usage information may wish to restrict an 

operators ability to clear the material usage data at the controller. This option allows you to remove the 

floor operators ability to clear this data. Press to toggle between CLEAR DATA PROMPT ENABLED 

and CLEAR DATA PROMPT DISABLED. 

SELECT DATE FORMAT - Sets System Date and Time 

Press ( ,1,1) to set the date format and to enter the correct date and time into the real-time clock. 

Correct date and time is helpful if you are retrieving information using a printer or are collecting data by 

computer. 

The first display will indicate USA or EUROPE date format. 

Use the CE key to toggle from one to the other. 

USA will cause all dates to be displayed MONTH/DAY/YEAR. 

EUROPE will cause all dates to display DAY/MONTH/YEAR. 

Press * to enter the current date and time. Enter the date and time using the keypad numbers. The date 

and time fields will advance as numbers are entered. After entering the year, the controller will exit to 

program mode. 

The correct date and time have been entered at the factory and should never have to be reset. Of course 

you may be in a different time zone. 

Save System Settings from ROM to RAM 

Press (*,1,2) to move the PARAMETER table from ROM to RAM. 

This allows system to operate with the parameters that were originally supplied as default numbers with 

the system. 

EXPLANATION: 

All PARAMETERS are stored in a table that resides in three places: ROM, RAM, and EEPROM. 

ROM (Read Only Memory) is the chip on the circuit board that cannot be altered in any way except by 

physically replacing the entire chip. It contains the program and the copy of the parameter table that we 

supply as standard with all controllers. 

EEPROM (Electrically Erasable Programmable Read Only Memory) is the portion of the processor that 

can be altered by the computer by special request only; data stored here is not lost even if the battery 

backed up RAM should loose power. EEPROM contains all parameters and control numbers that are 

unique to your system. It holds the information that is automatically retrieved when the CLEAR 

procedure is performed (see below). This information may be retrieved for use only by special request 




from the keypad. At the factory we have set what we believe to be the proper parameters for your 

application into the EEPROM. 

RAM (Random Access Memory) is the chip on the circuit board where the processor keeps track of and 

stores constantly changing data. It is the area that would go blank if power were removed from it. We 

have provided a battery back-up for the RAM so this should never be a problem. On normal power off 

and power on, the data and parameters that reside in RAM are not lost. However, RAM is the portion of 

memory most easily corrupted by the poor electrical environment of a factory. Should something cause 

the data in RAM to be lost or corrupted, a "CLEAR" procedure is provided that will retrieve the parameter 

table stored in the EEPROM and copy it into RAM memory for use. If you make changes to the 

PARAMETER table, these changes reside only in RAM and may be lost in the event of a computer 

malfunction. To insure that your changes are saved for future runs, it is necessary to move this 

information from RAM to the EEPROM (*23, next). 

NOTE: The battery used for backup is a lithium battery that is part of an I.C. 

chip on the board. It has an expected 10-year life and is not easily accessible 

for replacement. Should it fail, we suggest that it be replaced at our factory. 

Save System Settings from RAM to EEPROM 

Press (*,2,3) to move the PARAMETER table from RAM to EEPROM. This information is then available 

for retrieval using the "CLEAR" routine or by using the *32 function described next. 

Save System Settings from EEPROM to RAM 

Press (*,3,2) to move EEPROM information to RAM. This is useful for retrieving special information 

tables that you may have stored earlier in the EEPROM. Also, if you have been making changes to RAM 

tables and now wish to restore all parameters to what they were at power up, this is the function to use. 

NOTE: The three functions, *12, *23, and *32, are easily remembered if 

you think of the 1, 2, 3 keys as ROM, RAM, EEPROM. The first digit 

selects the source, the second digit the destination. 

LIW Model Selection 

Press (*,2,2) to select the Loss-In-Weight model. Setting the LIW Model to one of the 4 options will also 

set the parameters LLF (Loss in Weight Low Level Fill in grams) and HLF (Loss in Weight High Level Fill 

in grams). LIW Model options are: 

LIW05 (Sets LLF to 2500, HLF to 5000) 




Set Material Types for each Hopper (12 Software Controllers Only) 

Press (*,1,4) to set components to one of four options. 

The display will look like this: 

(1TY= REG), (1TY= NAT), (1TY= ADD), or (1TY= OFF). 

This is the component number and the TYPE it is set to: 

REGRIND, NATURAL, ADDITIVE, or TURNED OFF. 

Press the "CE" key repeatedly to scan the four options. 

When proper selection is displayed, move on to NEXT component by pressing the "*" key. 

REPEAT the "* CE" sequence for ALL components you use. 

The * key will walk you through all components. 

The CE key will change the TYPE for a component. 

Components NOT CONNECTED, or NEVER USED, set to OFF. 




EXIT will exit the sequence at any time. 

After EXIT, if display says (NEED NAT) then you have specified an ADDITIVE without specifying a 

NATURAL. This is an unacceptable condition. 

FOUR dispense valve systems use components 1 to 4. 

TWO dispense valve systems use 1 and 2. 

SIX dispense valve systems use 1 to 4, then 7 and 8. 

Panel front OUTLETS are always components 5 and 6. 

ROM Check Flag 

Press (*, 2,5) to check the ROM-CHECK flag. Whenever your controller is on, the processor is 

continuously performing an integrity check of the ROM program chip supplied with the unit. Each 

complete scan of the program takes about one minute. If any single check reveals an incorrectly set bit, 

the ROM CHECK flag is turned on. This flag is checked every time you power up. If the flag has been 

set the display will say (ROM BAD), followed by the date and time of the last check that was found bad. 

If the flag has not been set, (ROM OK) will be displayed. To turn the flag off, you must select this option, 

(*25), and, with (ROM BAD) displayed, press the "CE" key. This will clear the flag and it will remain off 

until another error is detected. The seriousness of the problem will be somewhat indicated by the date 

and time of the last bad check and how frequently you find it necessary to turn this flag off. Even with an 

error, your controller may still work perfectly. However, we suggest you request a new program chip from 

us as soon as possible. 

Batch Processing Alarm 

Press (*,3,3,) to turn on a special alarm condition. Press * to toggle between (AL STD) and (AL- 

BATCH). If you are running using the BATCH key, and (AL-BATCH) is selected, then the ALARM will 

sound when a batch is completed. 

END CYCLE WITH: BIN EMPTY, BIN FULL 

This flag for SPECIAL APPLICATIONS ONLY. 

Press (*,4,4) to tell the controller to end a cycle when the weigh bin is FULL. Use the * key to toggle 

between BIN EMPTY or BIN FULL. 

Normal operation is to end the cycle BIN EMPTY. The BIN FULL option is only for special installations 

where the sensor has been relocated BELOW the mix chamber and the instructions to do otherwise. 

SET MANUAL MODE PASSWORD 

Press (*,4,5, followed by a 5 digit number) to change the PASSWORD number for entering the MANUAL 

mode. The system is supplied with the number "11111" as the password number. If you wish to restrict 

use of this mode to only yourself, you may make up your own number and enter it here. 

WSD Systems Only – Change Weight Dispense Range 

Special function - WSD DISPENSE systems only. 

This function alters the range of requested dispense weights. 00.1 to 99.9 is standard. 001 to 999 is 

optional using this function. Dispense systems are generally used for rotational molding. 

Weigh Bin Double Dump 

Press (*,5,2) to cause the weigh bin dump valve to operate two times. We call this a "double dump". If 

you have problems with material hanging up in the weigh pan, this may help shake it loose. 

Use the * key to toggle between (DBLD OFF) and (DBLD ON). 

Press EXIT when done. 

PRINTED REPORTS - Cycle-by-Cycle Printout 

Press (*,5,4) to set flag for a printout of data after each full dispense cycle. With this flag ENABLED and 




with a printer on line, four lines of information about the dispense cycle that just occurred will be sent to 

the printer. Press * to toggle between ENABLED and DISABLED. This information includes dispense 

weight and percentage of each component, the internal rate numbers used by the computer to determine 

dispense time, and the actual dispense time of each component. This is excellent information to track the 

accuracy of each dispense cycle and the accuracy of the entire system over an extended period of time. 

See: PRINTER OUTPUT for a more detailed explanation. 

Alternate Color (For Liquid Color PIAD system) 

For LIQUID COLOR applications only. This function usually operates in conjunction with an additional 

two air solenoids mounted on the blender frame. 

Press (*,5,7) to allow automatic switch over to a full drum when the current drum of color runs out. When 

function is off, display will say LIQ OFF. Press * to toggle to COL 10. When display says COL 10, the 

color setting applies to output 10 only, the standard COLOR output. When display says COL 10 → 11, 

this means that output 10 is the starting output, and when no weight is detected after a dispense, the 

output switches to output 11. The "11" is determined by the parameter (LIQ 11011). You can change the 

secondary output by changing the parameter. 

If output 11 is also empty, the output switches back to 10. See parameter (LIQ 11011) for more 

information. 

If enabling *57 and component 10 is not set as an additive, the display will briefly show *** LIQ ERROR 

***. 

WSB COMMUNICATIONS – Sets the Blender ID number 

Press (*,6,6) to enter an identification number for this particular weigh scale blender. This I.D. number 

will appear on all printed reports. If you have more than one unit, this helps to identify reports. If you are 

using a computer to automatically gather data, then each controller must have a unique address. Valid 

numbers are 000 to 255. When connected to a computer, do not use the number 000 for identification. 

ADD & COL AS % MIX - Special Applications Only – Additive Percent of Mix 

Press (*,7,2) to change the Additive settings to be interpreted as percent of the entire MIX instead of 

percent of the Natural. The display will say ADD & COL AS % MIX ENABLED or DISABLED. Press "*" 

to toggle flag between ENABLED and DISABLED. This option has been added for customers with 

unique requirements. 

Leave this flag OFF, (APM- OFF), unless you have specific instructions to do otherwise. 

CAUTION: With this flag set, additive settings combined must NOT exceed 100 percent. From a 

practical standpoint, they should not exceed 10 percent combined. 

MAX Weight Alarm 

Press (*,7,4) to set a flag that will cause the system to stop and the Alarm to activate when MAX weight is 

exceeded. This might occur if a valve sticks open or slightly open. Normally the system recovers 

automatically from such events with only the one batch blended incorrectly. Set the flag only if you want 

the system to stop and alarm. 

Press * key to toggle between ENABLED and DISABLED. 

Press EXIT when done. 

WEIGHT LOSS ALARM - Weight Reading Alarm 

Press (*,7,5) to set a flag to ALARM if the weigh bin weight drops more them 20 grams during a cycle. 

This serves to detect and report a weigh bin problem, such as material leaking from the bottom of the bin. 

Press * key to toggle between ENABLED and DISABLED. Press EXIT when done. 

Parameter Printout 

Press (*,7,7) to print a copy of all internal parameters. A printer must be connected and ready. 

Up to 13 lists will print, a General list and 12 component lists. Only components that are turned 

"on" will print. Four columns will print, RAM; ROM; 200 and 900 series tables; and EEPROM. 




Identifying headings print above each column. 

Change Program Mode Password 

Press (*,7,8, followed by a 5 digit number) to change the PASSWORD number for entering the 

PROGRAM mode. The system is supplied with the number "22222" as the password number. If 

you wish to restrict use of this mode to only yourself, you may make up your own number and 

enter it here. If you forget your password number, call us. We can help. 

Precision Ratioing - Additives 

Press (*,8,2) to produce a precision ratioing of a selected Additive. Press CE to toggle between 

PRECISION RATIOING DISABLED, PRECISION RATIOING COMPONENT: 1, PRECISION RATIOING 

COMPONENT: 2, etc. Only those components already designated as an ADDITIVE will be displayed. If 

precision rationing is selected, the specified additive (selected by the *82 function) will dispense BEFORE 

the Naturals, instead of after. Natural dispenses occur after the selected additive dispense and are 

calculated to assure the most exact percentage ratio for the selected component. Because the Natural 

dispenses are larger, this method allows for more exact ratioing of the one selected critical component. 

Progressive Metering 

Press (*,8,3) to select "Progressive Metering" option. Progressive Metering allows for more accurate 

dispenses of selected components. However, cycle time will be extended by a few additional seconds. 

In normal operation blenders target a dispense of the full requested amount in one try. This almost 

always works, and generally will fall within acceptable upper and lower error limits. Making the dispense 

in one try allows for high throughput rates while still achieving a level of accuracy acceptable for most 

processors. When the accuracy of one particular component is critical, or the process depends on 

maintaining a tighter tolerance of this component, customers may lengthen the blend cycle time slightly 

to achieve this higher level of accuracy. 

The *83 function is used to turn on the progressive metering function for a selected component. This sets 

parameters which will cause the dispense to occur in several progressively smaller dispenses. This 

results in a more accurate dispense. 

The first dispense targets only 85 percent (the default percentage) of the full required amount. After 

careful weighing, each successive dispense targets 50 percent of the remaining shortage. This continues 

until the amount reaches, or is within 1 percent of, the target. In this manner the software "sneaks up" on 

the target, providing the maximum achievable accuracy possible. 

When a component is selected and turned ON, the corresponding PT and RP parameters are set to PT 

00085 and RP 00001. 

The keypad sequence: 

Press *,8,3. Display will say COMP: 1T. 

Use the "*" key to walk through all the components. 

Use the "CE" key to toggle a component ON or OFF. 

When ON, Display will say COMP: # T: 85 

You may change the 85 by entering a different number. Too low a setting will just add time. Too high will 

cause occasional overshooting. 

Press EXIT when done to save new settings. 

Backdoor Password 

Press (*,8,6) to select a new "Back Door" password for your software. Display will say BACKDOOR 

PASSWORD Select (0-9): 00000. Enter 00001 up to 00009 to select one of nine new backdoor 

passwords. Contact us for the actual number. If you just want to kill the use of a backdoor password 

altogether, just enter a number from 1 to 9, and don't call us. Then no one in you plant will know the 

number. But we still will, just in case. Then your own selected regular password will work and as long as 

you don't forget it, your ok. 

Blenders are pre-programmed with two normal passwords; (22222) is the default password for the 

PROGRAM mode, (11111) is the default password for the MANUAL mode. You can alter these 

passwords to any 5 digit number, but you must know the current PROGRAM password to change it. If 




for some reason the password has been altered and you can not remember it, we have a special 

"backdoor" password that will let you in no matter what. For obvious reasons, we do not provide that 

password in this manual. You must call us. However, there is a problem. If the wrong person in your 

factory obtains this password, then he will always have access to the Program mode of the blender no 

matter what. 

Now, with this star function, you have the option to select from 10 different "backdoor" passwords. If your 

current "backdoor" password is known to the wrong person, you can call us for a new one. We will not 

give these backup passwords to just anyone. In fact, since only I know them, it is not that easy to obtain 

these numbers. 

To activate a new "backdoor" password, you will enter a number from 00000 to 00009 using this star 

function. Each number activates a different password. Entering 0 activates the current backdoor 

password, the one we have used for over 10 years. For a new one, call us and talk with someone you 

know here in the office and they will supply a number from 1 to 9, and the associated new "backdoor" 

password. 

After this new "backdoor" password is selected, you can safely change the regular password to one only 

you know, and use that in normal production. No one will be able to use the backdoor to get in. If you 

forget your regular password, and you also forget which backdoor password you selected, then we will 

help you go through the entire list to find the one that works. 

Volumetric Mode 

Press (*,8,7) to set flag for operation in a VOLUMETRIC mode. Use the * key to toggle the flag 

ENABLED or DISABLED. Press EXIT when done. When power is turned off this flag is always 

reset to OFF. With this flag ENABLED (VOLUMETRIC mode), the load cells are completely 

ignored. Error correction and rate recalibration does not take place. The unit functions like a 

volumetric feeder without checking or correcting for errors. Since load cell readings are 

ignored, this flag allows operation even if the load cells become damaged. Dispense times will 

be based entirely on the WT and TI parameters. 

Printout Display 

Press (*,8,8) to force a printout of the display on the controller front. DATE, TIME, Machine number, and 

display will print: 

Date: 11/09/93 

Time: 17:22:01 

Machine number: 002 

Display Readout: P 500.0 

This is useful for obtaining printed verification of load cell accuracy ISO and other international quality 

program rules. 

The recommended procedure is: 

1. Place the unit into the Program mode. 

2. Press *88 for printout of empty bin TARE weight. 

3. Place a KNOWN CERTIFIED WEIGHT into the weight bin. 

4. Press *88 again for printout with the weight added. 

5. The different between the two weight printouts should equal the KNOWN CERTIFIED WEIGHT. 

Select Weight Unit 

Press (*,8,9) to select the desired weight unit (GRAMS, KILOGRAMS, OUNCES, POUNDS) for 

readout of data. For the U.S.A. systems are supplied with POUND readout selected. 

KILOGRAMS are preferred for nearly all countries outside the U.S.A. GRAM or OUNCE 

readouts are appropriate only for very short runs or short demonstrations. Use the * key to 

toggle through the four possible selections. Press EXIT when the weight unit you want is 

displayed. 

SELECT COMM. SPEED (Set Baud Rate) 




Press (*,9,5) to set the baud rate of the COM port. Options are 1200 baud or 2400 baud. Note: 

The default baud rate is 1200. If the baud rate is set to 2400, the G2-SA (if in use will also have 

to be set to 2400 baud by installing a jumper pin on an internal board. If you wish to do this, 

contact Maguire Products and request the document regarding the G2-SA baud rate. 

Document is also available online: www.maguire.com 

Display Load Cell Raw Signal (counts) 

Press (*,9,8) to set flag for RAW-SIGNAL readout in place of gram readout of scale weight. 

Power-On will always set this flag to OFF. Use the * key to toggle flag ENABLE or DISABLE. 

Press EXIT when done. A raw signal readout is useful to demonstrate the extreme sensitivity of 

the load cells. The raw signal readout bypasses the calibration math routine. Load cell function 

can be monitored without concern for any improper weight calibration that may have been 

done. 

These functions were explained previously in the MANUAL MODE section: 

CLEAR ALL DATA 

Press (*,0,0) to CLEAR ALL DATA fields. Press (*,0,0) to CLEAR ALL DATA fields. These are 

the material usage totals that are viewed with the VIEW key. If you are tracking material usage, 

you should record these numbers periodically but clearing these totals is entirely optional and 

not necessary. 

After VIEWING the data or printing of data using the VIEW,* key sequence, a display of 

(00=CLEAR) will appear for 5 seconds. During this 5 seconds you may reset all data fields to 

zero by pressing 00. Pressing any other key or waiting 5 seconds will exit this sequence without 

clearing data. 

Enable Weight Calibration of the Load Cells 

Press (*,9,9) to set flag to enable Weight Calibration of the Load Cells. In later model 

controllers you can specify WSB CAL or LIW CAL. Power On will always set this flag to OFF.

Parameters Introduction 

All WEIGH SCALE BLENDER controllers operate according to certain internal PARAMETERS. Because 

customer requirements vary widely, we have made over 160 parameters accessible for change through the 

keypad. There is one GENERAL group and twelve COMPONENT groups. 

BRIEF explanations are given first. 

FULL information is given in the section that follows. 

Parameters values shown here are initial ROM values of a model 940. Initial values for 

other models are listed at the end of this section. 

Parameters are five digits, with leading zeros added. 

TIMES 

WEIGHTS 

PERCENTS 

TIMES are expressed as seconds, minutes, or interrupts. 

(244 interrupts = 1 second). 

are always expressed as GRAMS. 

100 and 200 models use tenths of grams: (xxxx.x). (00010 = 1 gram) 

400/900/1800/3000 models; full grams: (xxxxx). (00010 = 10 grams) 

are expressed in tenths for settings (0xxx.x), and full percents for other percentage 

references (00xxx). 

Navigating Parameters 

In the COMPONENT lists: 

The TOP parameter (TYPE) is ALWAYS accessible. 

The others are NOT accessible unless TYPE is set onto a setting. 

The First press of the PARA key will enter the GENERAL list at the top. Then the first press of the SET key will 

move to top of the first component list. Press the PARA key to move down in any list. 

While in one COMPONENT list, press the SET key to jump to the same relative position in the next list. This 

allows rapid scanning of like parameters in all component groups. 

To change a displayed parameter enter a new number in place of the old one. CE will cancel a number entry 

before the last digit is entered. The purpose of each parameter is explained elsewhere in this manual. 

In any component list, if TYPE is set to "OFF"; (_TY= OFF); other parameters in that list are not accessible. 

EXIT will exit the sequence at any time.

MIX TIME 

This parameter times how long the MIX motor runs. 

JOG COUNTS and TIME 

JOG indicates the number of times the blade will jog after initial mixing is ended, plus the time interval 

between these jogs. 

TIME the Flow Control valve delays before opening (Seconds). 

This parameter holds each batch in the mix chamber for a time to assure mixing. This is only for units 

equipped with the optional flow control valve under the mix chamber. 

WEIGH BIN DUMP TIME at end of cycle. (Seconds) 

This parameter times how long the weigh bin dump valve opens to empty. No change is required. 

Maximum variation in GRAMS between two consecutive weight 

Readings for reading to be accepted. (x or x.x) 

KDF controls sensitivity of weight readings during calibration of load cells. No change is required. 

WDF controls the sensitivity of weight readings during normal operation. If excessive vibration interferes 

with weight readings you may have to increase this number. 

Excess GRAM weight before dispense is aborted. 

This parameter controls sensitivity of the emergency "bailout" routine that prevents overfilling of the weigh 

bin. No change is required. 

These next three parameters, ROC, ROV, and RHL help control regrind usage. 

ROC indicates the PERCENT of REGRIND that will be treated as natural when COLOR and ADDITIVE 

dispenses are calculated. This adds some color or additive to your regrind. 

ROV is for closed loop fully automatic reprocessing of regrind scrap. This parameter will detect when more 

regrind is being produced than consumed, and override the current setting to use a higher amount. This 

helps prevent material backing up in your grinder. 

RHL has effect only if level sensors are added to your unit to detect material level in the regrind hopper. 

These level sensors can alter regrind percent usage. 

Full batch weight, determined by weigh bin size. 

Maximum GRAM weight the software will target. 

FUL is the target weight that is blended each cycle. Change only for extremely fluffy or very heavy material. 

MAX prevents overflowing of the weigh bin. It is reset automatically if the FUL parameter is changed. 

The highest and lowest acceptable TARE weights for 

Blend cycle to start. (full or tenth grams) 

TL prevents starting with the weigh bin out of place. No change is required. 

TH prevents starting with a full weigh bin. Change TH only if clumps of material hang up in the weigh bin. 

MINUTE interval between automatic print of TOTALS. 

This parameter will cause your system to PRINT MATERIAL TOTALS automatically. A printer must be 

connected. 

Delay before cycle start. (Interrupts) 




This parameter is the time that the sensor must be uncovered before a cycle will begin.

This prevents excessive swings in flow rates by the software. Do not change. 

Dispense settle TIME before a weight reading is taken. 

The time (interrupts) allowed for material to SETTLE in the weigh bin before a weight is taken. Lengthen 

only to slow the next cycle start, thereby lowering the pile of material in the mix chamber, and, in some 

cases, improving mixing.

1CS 00000 

DESIGNATES MATERIAL TYPE for this component. 

Material types are: REG, NAT, ADD, or OFF=NOT USED. 

(0=OFF, 1=REG, 2=NAT, 3=ADD) 

These MUST be set using the *14 function before the system will operate. See: "TURNING ON OUTPUTS" 

to complete this.

Last digit = number of retries before ALARM. 

00001 to 00009 = sound alarm, hold process. 

00011 to 00019 = sound alarm, continue process. 

These parameters set ALARM functions. When material runs out, or does not dispense fully, these flags 

instruct the controller what to do. Default settings shown are for Natural, Color, and Additive to alarm, but 

not Regrind. 

1XT 00000 

1SE 01000 

Move decimal left on color and additive settings. 

These parameters allow entry of less then (00.1) percent for COLOR or ADDITIVE. 

When set to "00010" settings are read as X.XX percent. 

When set to "00100" settings are read as .XXX percent. 

Upper SETTING limits for thumbwheels (0xxx.x). 

Settings greater than limit are held to limit. (01000) = 100% 

These parameters can SET UPPER LIMITS to the thumbwheels. For color and additive, lower settings may 

help ensure expensive material is not wasted.

WT = the Weight portion of the dispense rate, calculated such that WT/TI equals the average of the last two 

actual dispense rates. 

TI = the TIME portion of the dispense rate. (Interrupts) 

These change AUTOMATICALLY during normal operation. 

They are Weight and Time portions of the flow rate calibration. 

Minimum valid dump rate GRAMS/sec. (full or tenth grams) 

Error correction is bypassed when dispense rate is lower. 

On power up, these are always set to 1. After several consistent cycles, they are reset to 80 percent of 

actual flow rate. These prevent excessive swings in flow rate calculations if material is running out. 

Allowable GRAM error within which NO correction is made. 

This is the acceptable error range for each component to prevent hunting. They adjust automatically over an 

extended time period to match the flow characteristics of each material. 

Reduce the target of the first try dispense. 

PERCENT shortage error that will force a retry. 

GRAM weight shortage error that will force a retry. 

Retries occur until both conditions are met. 

Lag TIME before dispense ACTUALLY starts. 

(mechanical response time, interrupts) 

These parameters state the lag time between when a device is signaled and when it actually begins to 

operate. Change ONLY if you change to non-standard equipment. 

Pulse rate of "MICRO PULSE" valves. 




Parameter List – Full Explanations 

GENERAL PARAMETERS 

FLG 

Change this to enable the RECIPE, BATCH, FAST, and TAG keys 

FLG is a SET of flags for turning on the RECIPE, BATCH, FAST and TAG keys. These 

four keys will NOT WORK and there associated functions are not available, unless this 

parameter is set properly. 

When all digits are set to 0 (FLG 00000), all four functions are OFF. 

The second digit set to 1 (FLG 01000), will turn the TAG key on. 

The third digit set to 1 (FLG 00100), will turn the RECIPE key on. 

The forth digit set to 1 (FLG 00010), will turn the FAST key on. 

The fifth digit set to 1 (FLG 00001), will turn the BATCH key on. 

The TAG key is useful for entering information that you wish to be "tagged" to all printouts 

and computer retrievals. Work Order and Operator numbers may be entered and 

displayed. Any computer loaded recipe number may also be displayed. 

The RECIPE key is useful for storing thumbwheel switch settings under a single 

numbered recipe. Up to 50 may be stored. To enable the RECIPE key, place a 1 in the 

3rd position of the parameter. 

The FAST key allows the unit to operate in a faster, higher output, mode. Output may be 

doubled in this way. To enable the FAST key, place a 1 in the 4th position of the 

parameter. 

The BATCH key allows you to signal that you have processed a certain amount of 

material, or for filling a barrel or gaylord to the top without the need for a level sensor to 

stop the process. To enable the BATCH key, place a 1 or 2 in the 5th (last) position of the 

parameter. 

Set to one (00001), the unit dispenses until the preset batch amount is reached and then 

stops and alarms. Set to two (00002), the unit alarms but continues running when the 

preset amount is reached. 

See KEYPAD section, for full explanations of these 4 keys. 

MIX 

Change this to run the mixer for a longer timed period 

MIX indicates the TIME that the mixer will run after the weigh bin dump valve opens. The 

number is the mix time in seconds. Adequate mixing can be accomplished in a short time. 

Additional mixing may cause separation and may create a static problem with the 

material. 

The default value is (00015), allowing an initial mix time of 15 seconds. A maximum 

setting of 29999 is possible, for a mix time of over 8 hours. Setting the mix time to 99 

(MIX 00099) will cause the mixer to run 360 seconds (6 minutes). 

JOG 

JOG indicates the number of times the blade will jog after initial 

mixing is ended, plus the time interval between these jogs. 




After mix TIME is complete, the mix blade is jogged about 1 turn every 1/2 minute. These 

jogs serve to level the pile of material in the mix chamber, insuring that the sensor does 

not remain covered for too long. The first 3 digits (030xx) of the parameter indicate how 

many jogs will occur. The last two digits (xxx30) indicate the frequency (or interval) in 

seconds. 

The default setting of (03030) produces a jog every 1/2 minute for up to 30 jogs. You 

may lengthen or shorten these numbers as required. A maximum setting of (29999) 

produces a maximum jog time of over 8 hours. 

FCV 

Delays opening and closing of the flow control valve 

FCV controls three different items: 

1) Digit 1 can reverse the output logic of the computer. 

2) Digits 2 and 3 set the time delay before closing. 

3) Digits 4 and 5 set the time delay before opening. 

The most important and primary use of FCV is to set the TIME, in seconds, that the flow 

control valve delays before opening (4th and 5 th digits (FCV 000xx). If your unit is 

equipped with a Flow Control Valve, under the mix chamber, it is programmed to open 

whenever the sensor is covered. It will close again immediately when the sensor is 

uncovered. This assures that material has time to mix before dropping into a bin below. 

When a batch is dropped into the mix chamber the sensor is covered. To prevent 

unmixed material from dropping immediately out the bottom, the mix valve is delayed for a 

time to allow mixing to occur first. This parameter controls the time that the Mix Chamber 

Valve remains closed after a batch has been dropped. 

The primary function of the valve is to assure mixing. As such it seems best to keep as 

high a level as possible in the mix chamber. However, if the chamber gets too full (over 

the blades), mixing is not as good. To allow the chamber to empty to a lower level after 

the sensor is uncovered, we can also DELAY the CLOSING of the flow control valve. This 

is done by using the 2nd and 3rd digits (FCV 0xx00) to specify a delay time. (FCV 00206) 

delays closing by 2 seconds. 

If the first digit is set to a 1 (FCV 10006), the signal output to the air solenoid is reversed. 

Normally, the computer puts out a voltage to open the valve. With this flag set the 

computer puts out a voltage to close the valve. For this reverse logic to work correctly, 

you must reverse the air lines to the flow control valve air cylinder. 

Normal power-off position for the valve is closed. Some customers prefer the valve open 

when all power is off. This option allows this reversed "power off" position. With power 

on, no difference is apparent. 

DTI 

Probably no need to ever change this 

DTI is the maximum TIME allowed for the weighing bin to dump at the end of the cycle. 

The software will close the bin earlier if it detects no weight change occurring. This time 

determines the maximum time that is allowed for the bin to empty. We set this maximum 

time limit according to the model and batch size. 

KDF 

WDF 

Typically No change required - Change only if you have an extreme vibration problem 

KDF and WDF are the maximum acceptable variation in GRAMS between two 

consecutive weight readings. One weight reading requires 1 second of time. Two 




readings are always taken and they must be within KDF grams of each other to be 

accepted as valid. Readings are taken continuously until two consecutive readings meet 

the criteria. This prevents a single accidental bump of the scale from causing a grossly 

inaccurate reading. WDF also allows the first digit to determine how long a reading is 

taken. A 1 in the first position indicates ½ second per reading. 2 means 1 second, 3 

means 1.5 seconds, up to 5 which is 2.5 seconds. The higher this number the slower the 

blend rate, but the more reliable the readings. 

KDF is used for load cell calibration weights, WDF for starting tare weight and component 

dispense weights. 

BER 

Change only if severe vibration causes problems 

BER is the BAILOUT ERROR weight. Dispenses are controlled by very accurate timing. 

However, as a precaution, the weigh bin is constantly monitored during each dispense. If 

bin weight is found to exceed target weight during the dispense, then a BAILOUT occurs. 

This ends the dispense immediately just as if the end of the dispense time period had 

been reached. This in no way effects the accuracy of the remainder of the cycle. The 

dispense is checked and retries will occur if 

required. 

A bailout does not occur unless target weight is exceeded by the weight given in the 

BAILOUT ERROR parameter. This is primarily to prevent vibration from causing a false 

bailout during very small dispenses. We set this parameter to a default of 00200 (20 

grams or 200 grams). If vibration is causing false bailouts, then you may want to set a 

higher value in this parameter. 

If the BER parameter has a 1 in the last position, (BER 00201), then a printout will occur 

of all cycle data anytime a bailout occurs for any single component. This is helpful if you 

want to be aware of occurrences where dispenses significantly exceed target. This will be 

the same information that you see when the PRINT flag is on (*54). A printer must be 

connected. 

ROC 

Allows for adding some ADDITIVE to one of the REGRIND portions 

ROC indicates the PERCENT of one REGRIND that will be treated as natural when 

ADDITIVE dispenses are calculated. If you feel it is necessary to ADD (or subtract) color 

or additive to your regrind, this parameter will automatically see that this is accomplished. 

The first digit is 0 to add, 1 to subtract. 

The second digit is the REGRIND component number you will be making this adjustment 

for. 

The last 3 digits indicate the percent of this Regrind component to add 

to, or subtract from, the Naturals when computing Additive dispenses. 

EXAMPLE: ROC set to (ROC 01020). 

The first 0 means add. The 1 is component 1. 

The 20 means take 20 % of component 1 (a Regrind) and ADJUST the total of all 

NATURAL dispenses upward by this amount. Whatever amount of component 1, 

Regrind, is added, 20 percent of this amount will be added to the Natural amounts before 

a color calculation is made. 

Regrind dispense = 600 grams, Natural portions = 1400 grams. 

At 4 percent, if ROC=00000, Color would be 56 grams. 




If ROC=01020; increase Natural by 20 % of 600, (120 grams). 

Color is now 4 % of 1520 grams (1400+120), or 61 grams. 

In some cases, the addition of pre-colored regrind tends to produce overall better coloring 

because of an initial more uniform dispersion of pigment. In this case you may want to 

add LESS color to the Natural portions when Regrind is present. Placing a 1 in the first 

digit of the ROC parameter (ROC 10000), will cause a portion of this Regrind component 

to be SUBTRACTED from the Natural portions, instead of added. 

EXAMPLE: ROC set to (ROC 11020). 

The first 1 means subtract. The second 1 selects component 1. 

This means take 20 % of component 1, a Regrind, and reduce the NATURAL portions by 

this amount. Whatever amount of component 1 is added, 20 percent of this amount will 

be subtracted from the Natural amounts before a color calculation is made. 

Component 1 dispense = 600 grams, Natural portions = 1400 grams. 

At 4 percent, if ROC=00000, Color would be 56 grams. 

If ROC=11020; reduce Naturals by 20 % of 600, (120 grams). 

Color is now 4 % of 1280 grams (1400-120), or 51 grams. 

ROV 

ROV and RHL parameters work together. Their combined purpose is to allow the 

adjustment of one Regrind component up or down based on input from one or two lever 

sensors. 

LEVEL SENSORS are required for this parameter to work. 

Both ROV and RHL must be set for these parameters to have any effect. 

The component being controlled is ALWAYS automatically 

assigned to the bottom set of thumbwheel switches. 

The first digit of the ROV parameter indicates which component is controlled by the 

adjustment routine. Only components 1 through 9 may be controlled. 

The last digit determines the adjustment rate. Zero in the last position means make the 

full adjustment immediately. Any value from 1 to 9 indicates the percentage adjustment 

that will be made each cycle when the level sensor condition changes. See RHL below 

for examples. 

RHL 

LEVEL SENSORS are required for this parameter to work 

Use only if you have regrind level sensors fitted 

RHL instructs the controller to change the regrind setting of one selected regrind 

component if optional level sensors in the regrind hopper indicate high or low conditions. 

The component to be changed is determined by the first digit of the ROV parameter 

above. 

If set to all zeros (RHL 00000), then this parameter is ignored. 

ROV alters the way RHL is interpreted. 

If the last digit of ROV = 0, (ROV x0000), then RHL numbers indicate NEW settings that 

are to be run when regrind level is high or low. 

If the last digit of ROV = 1 to 9 (ROV x0001) to (ROV x0009), then RHL indicates upper 

and lower regrind usage limits only, and regrind usage will be adjusted slowly, to these 




limits, based on the ROV number. 

IF ROV equals zero (ROV 10000): 

In this (and all) examples, ROV is selecting component 1 as the controlled component. 

(ROV 10000) 

If RHL is set to any value, the first 3 digits of the parameter indicate a new Regrind setting 

to use when the material level is ABOVE the HIGH level sensor; (sensor is covered). The 

last 2 digits indicate a new setting to use if material level is BELOW the LOW sensor; 

(both High and Low sensors are uncovered). 

In other words, RHL allows the selection of a percentage that is HIGHER then normal, 

and a percentage that is LOWER then normal. NORMAL is what you put on the bottom 

thumbwheel switch. 

Sensors are assumed to be covered when NO signal is returned. If a sensor is unplugged 

from the controller, it is read as "covered". 

If you only have ONE SENSOR, it must be used as a HIGH level sensor. The absence of 

a sensor is read as a covered sensor; so the absence of the high sensor would signal the 

system to run at the high setting all the time. This would not be acceptable. The absence 

of the LOW sensor simple prevents the system from ever thinking it is very low. This is 

acceptable. 

With a high level sensor only, the system switches between the NORMAL thumbwheel 

setting and the HIGH setting indicated by the first 3 digits of the parameter. The last 2 

digits have no effect, since a LOW condition is never detected. 

Sensors that we supply are wired correctly for this logic. If a "Bindicator" or similar device 

is used, with a micro-switch dry contact closure signal, then wire to the normally CLOSED 

contact so that the signal OPENS when regrind covers the bindicator paddle. 

The circuit board "pin outs" for each sensor are positive, ground, and signal. If you are 

wiring using a dry contact closure, only the positive and signal lines are used. When the 

contact is open, the signal is pulled to ground internally through a resistor. 

Example: RHL is set to 90 and 10 percent (RHL 09010). 

ROV last digit is set to zero, (ROV 10000). 

The "Regrind" thumbwheel switch is set to 25 percent (025). 

The Software logic is as follows: 

If material level is high, above the high sensor, 

the HIGH sensor is COVERED, (returns NO signal); 

Regrind runs at the HIGH setting; 90 percent. 

If material level is in the middle, between sensors, 

the High sensor is NOT covered, (returns a signal), 

the LOW sensor IS covered, (returns NO signal), 

Regrind runs at the THUMBWHEEL SETTING; 25 percent. 

If material level is low, below the low sensor, 

BOTH sensors are NOT covered, (both return a signal), 

Regrind runs at the LOW setting; 10 percent. 




IF ROV equals 1 to 9 (ROV 10001 to ROV 10009): 

All the same rules given above apply, except that the thumbwheel switch regrind setting 

does not jump in one step to a new setting, but, instead, moves slowly to the new setting 

which acts as a limit. The usage adjustment is made each cycle by the amount specified 

by the ROV parameter. 

Example: RHL is set to 10 and 90 percent (RHL 09010). 

ROV last digit is set to 3 (ROV 10003). 

The "Regrind" thumbwheel switch is set to 25 percent (025). 

The Software logic is as follows: 

If material level rises, goes above the high sensor, the HIGH sensor is COVERED, 

Regrind usage will increase 3 percent each cycle up to a high limit of 90 percent. 

If material level is in the middle, between sensors, the HIGH sensor is NOT covered, the 

LOW sensor IS covered, Regrind usage will change 3 percent each cycle, moving back 

toward the THUMBWHEEL SETTING of 25 percent. 

If material level drops below the low sensor, BOTH sensors are NOT covered, Regrind 

usage will decrease 3 percent each cycle down to a low limit of 10 percent. 

FUL 

Change only for extremely fluffy or heavy material 

FUL is the full batch weight in GRAMS set at the factory to 1000, 2000, 4000, 9000, or 

18000 grams, depending on model. The criteria for this number is to not exceed the 

volume capacity of the weigh bin and to not exceed the load cell capacity. On a 9000 

gram system, load cells are rated for 10,000 grams each. Total load capacity is 20,000 

grams. The weigh bin, when empty, weighs about 2400 grams, leaving a net capacity of 

17,600 grams for weighing material. However, a dispense over 13,000 grams probably 

would exceed the volume capacity of the bin. We have set the full batch weight to 9000 

grams which we considered a conservative full batch weight. Higher batch weights will 

increase maximum throughput rates. 

If your Regrind is very fluffy and you use a lot of it, you may find 9000 grams to be too 

much volume for the bin. Select a lower total batch weight such as 7000 to ensure that 

the bin never overflows or fills completely to the dump valve. 

DISPENSE STATION CONFIGURATION. 

When this controller is used on a dispensing system (Model WSD; not a Weigh Scale 

Blender) where you may wish to frequently change the dispense weight of each batch, 

this parameter acts as a flag to allow that mode of operation. When FUL is set to 00001, 

the controller will read the top thumbwheel switches as the full batch weight, in pounds 

from 00.1 to 99.9, and will target that weight for the batch. When set to 00002 it will read 

the switch as kilograms (00.1 to 99.9). 

See "MAX", next, for more information. 

MAX 

Set automatically if FUL parameter is changed 

MAX is the maximum gram weight, which the software will allow as a target for 




dispensing. The initial Full weight target is set by the FUL parameter. As dispenses 

progress, an over dispense of one component may cause a new target to be calculated 

for future dispenses in order to maintain proper requested ratios. A recalculated target is 

not allowed to exceed the value held in the MAX parameter. 

If you change the FUL parameter, the MAX parameter will automatically be set to a value 

50 percent higher then the FUL setting. 

DISPENSE STATION CONFIGURATION. 

This controller can be configured to operate as a dispense station (model WSD). This is 

generally done when exact weights of material or blend are required to place into a 

process, such as rotational molding. In this configuration, the thumbwheel switches tell the 

controller how much weight to dispense in pounds (or kilos). The FUL parameter is set to 

00001 or 00002 for direct reading of the top thumbwheel switch; or optionally, for recipe 

reading of the second thumbwheel switch. 

When dispense weight you request exceeds the amount specified in the MAX parameter, 

the unit will automatically make multiple dispenses that will add up to the requested 

amount. 

TH 

TL 

Change only if material sticks in the weigh bin 

TH and TL are acceptable error limits for TARE WEIGHT. 

Before a dispense cycle begins, the software checks to see that the weigh bin is in place 

and that it is not already full of material. To do this it looks at the starting TARE weight. 

If Tare weight is below the value of TL, (50 grams), the software assumes that the bin is 

either missing or hung up on something. In this case the ALARM sounds. 

If Tare weight is above the value of TH (100 grams), the software assumes material is in 

the bin. In this case the ALARM sounds and the weight bin dump flap operates in an 

attempt to empty the weigh bin. 

If you are processing a material that has a tendency to hang up in the corners of the bin, 

then you may wish to widen the range of acceptable starting tare weight. Since tare 

weight is always subtracted from dispense weights, these errors do not effect accuracy. 

PRT 

Change to get AUTOMATIC printing of material totals 

PRT, when set to any number other then zero, will cause the processor to output all 

current material usage totals, at regular time intervals, to the printer port. The number you 

enter will dictate the time interval in MINUTES. All timing starts from MIDNIGHT. For 

example, an entry of 00120 will cause totals to print at 2 AM, 4 AM, 6 AM, etc. Printing 

always waits until a cycle has just ended. A setting of 10000 is a special case. This will 

cause a printout after every cycle. A printer must be connected. If one is not, the routine 

will abort and blending will continue. 

DLY 

Consider changing if mixing is a problem 

DLY is the TIME the mix chamber level sensor must be uncovered before a cycle begins. 

The sensor must be uncovered without interruption for the full specified DELAY time. To 

prevent false starts from material movement caused by the mix blade, a minimum of 2 

seconds (00488) is recommended. 




Sometimes throughput is slow enough that each new batch buries the mix blade for a 

while. When this happens the material on top does not mix well. To reduce this, you can 

delay the start of a new batch by increasing the DLY parameter. The new batch is 

delayed and mix chamber level has time to fall before the next batch is added. 

PRC 

No change required 

PRC is the maximum allowable PERCENT rate change per cycle. If a large dispense 

error occurs, flow rate corrections do not exceed this percent number. This prevents large 

swings in timing of dispenses and provides for stable dispense rates under difficult 

conditions. For example, when dispense quantities are very small (one or two grams), 

overfeeding by several grams is a distinct possibility. This type of error represents a very 

large percentage error to the controller. 

However, a large correction would not be appropriate but, instead, would cause a 

"hunting" of dispense time that would result in further large errors. This parameter 

prevents this. 

STL 


STL is the TIME period allowed to pass after a dispense has occurred, but before a 

weight reading is taken. This settle time allows falling pellets to reach the bin and also 

prevents their impact with the bin from adding to the weight reading. 

LCL 

LCH 

LCF 

LCZ 

DS1 

DS2 

DS3 

DO NOT CHANGE THESE 

These four parameters are set to match the characteristics of the type of load cells used 

in your system. DO NOT ALTER THEM. LCL and LCH are the acceptable LOW and 

HIGH limits of load cell output expressed as raw signal counts per gram of weight. LCF is 

the lowest acceptable FULL scale load cell output expressed as raw signal counts per 

second. LCZ is the highest acceptable ZERO scale output. LCF and LCZ values are 

multiplied by 256 before being used by the software. 

Function in Dispenser mode only. 

Override top, middle and bottom thumbwheel switch settings. 

When the system is operating as a dispense system, (FUL 00001), the dispense weight is 

retrieved from the top thumbwheel switch or from the recipe file if the middle thumbwheel 

is set to a recipe number. 

If either DS1, DS2 or DS3 is set to any value greater then zero: 

Substitute DS1 for the TOP switch settings, 

Substitute DS2 for the MIDDLE switch settings, and 

Substitute DS3 for the BOTTOM switch settings 

These three parameters allow MLAN to download the dispense weight amount or recipe 

number. They also allow entry of a "locked in" amount or recipe. 

If BOTH DS1, DS2 and DS3 are set to 00000, then nothing changes. 

The middle thumbwheel switch setting for a recipe will override the top switch setting. 

When loading a weight into DS1, load 00000 into DS2 to be sure DS1 will control. 




SCR 

BCR 

Special Customer Request 

If a customer has a special software requirement that has no benefit to anyone else, then 

this request is hidden in the software and activated by the appropriate code number being 

entered into this parameter. Generally these requests are useless to anyone else. 

Use only for blenders with BAR CODE reader input. 

If you know ONE bar code input is required before a new cycle is initiated, set this 

parameter to 00001. The blender is then prevented from operating until one single valid 

input is received. If two inputs are expected, set this parameter to 00002, etc. When set 

to any value, the blender will not operate until the required number of scanned inputs are 

received. 

XCV 

XRC 

Extrusion Control Voltage 

(For Extrusion Control Systems only) 

XCV - "Extruder speed Control Voltage" is used in conjunction with our extrusion control 

software. This number can range from 0 to 1000 (XCV 00000) to XCV 01000), and 

determines the voltage output on pin S of the Amphonol connector. Pin R is the neutral or 

zero reference for this voltage output. 

The voltage ranges from 0 to 10 volts. 01000 = 10.00 volts. This parameter can be set 

manually, however it is intended to be controlled by the extrusion control logic or by MLAN 

communications in conjunction with our extrusion control software. 

Whenever the software control logic makes a change to this voltage, up or down, the 

controller display will say (RAMPING) during the time the voltage is being adjusted. 

XRC - "Extruder speed Rate of Change", determines the ramp up or ramp down rate of 

the XCV parameter, above. It can range from 0 to 10 (XRC 00000) to (XRC 00010). 

Default setting is 00004. 

When XCV changes, it does so gradually, making small incremental changes every 10 

interrupts, or about 24 incremental changes per second. The XRC parameter determines 

the maximum value of each incremental change. For example, if XRC is set to 1 then the 

XCV number will increment by 1 count (0.01 volt) every 10 interrupts, for a rate change of 

24 counts (0.24 volt) per second, which will produce a full range change from 0 to 10 volts 

over about 41 seconds. 

TCV 

TRC 

XTP 

Takeoff Control Voltage 


These parameters control a second 0 to 10 volt voltage output on for controlling Takeoff 

control speed. They operate the same as the XCV and XRC covered above except they 

move in the opposite direction, higher to reduce weight per foot, lower to increase weight 

per foot. 

Extrusion Control Trip Point 


The LAST THREE digits of the XTP parameter specify the TRIP POINT when software will 

make an adjustment to the throughput rate number, which will then cause a change in 

extruder speed. Speed is held steady until there is significant indication that the 




throughput rate is incorrect. The software analyzes each batch watching for any 

meaningful deviation from current controlling rate. These last three digits of this 

parameter specify the accumulated error, indicated as a percent of full batch weight, 

required to trip a change. For example, when set to 30 on a 200 series blender, this 

would indicate a 600 gram total error must accumulate before adjustment, 30 percent of 

the full batch weight of 2000 grams. 

The FIRST TWO digits indicate how many cycles must run without a rate adjustment 

before the operator is permitted to switch from voltage (manual) control to Throughput 

(automatic) control. This is a factor during startup only. Larger numbers assure a very 

accurate rate has been learned. This is preferred if you like the way your extruder is 

running and do not want any further adjustment unless a real problem is detected. On the 

other hand, if you know that you want output to be a predetermined value, like 1000 

pounds per hour, then switching sooner is better. In this way the operator can enter the 

rate he desires sooner, and the blender can immediately make any required adjustments 

required to target in on this rate. Too large a number causes delayed response, too small 

causes hunting. Larger is safer since you do not want "false" adjustments to occur. 

This parameter starts at XTP 50030, 30 percent of full batch weight accumulated error 

and 5 cycles required without adjustment before your operator can switch to the 

Throughput mode. A "T" is displayed when the 5 cycle requirement is reached. 

XAL 

Extrusion Control Adjustment Limit 

XAL limits the degree of change that the software can make in one adjustment cycle. 

Default setting is 00005, 5 percent. Operator entered rate changes are not limited. 

XUL 

Extrusion Control - Upper Adjustment Limit 

XUL sets an upper limit to how far the software can adjust the extruder speed (control 

voltage). If this limit is exceeded, then the adjustment is NOT made, and the ALARM is 

turned on. Pressing the V/T key switches the control to Voltage Mode. When pressed 

again, the unit returns to Throughput Mode, and a new Limit is set. Further adjustments 

may now occur to the new limit. 

Default is 00200, 2 volts. The idea is that once control is established, adjustments 

upward of more then 2 volts indicate conditions that should be attended to, a clogged 

screen pack for example. You may wish to reduce this number so that operators are 

warned well in advance of such conditions. 

CPL 

Yield Control - Counts Per Linear unit of measure 

Customers using Yield Control require a pulse generator, or shaft encoder, mounted on 

downstream takeoff equipment to signal the line speed to the blender. In operation the 

software displays GRAMS per unit length, which may be per foot, per yard, per meter, or 

whatever. For whichever unit length you select, enter the pulses per unit length in this 

parameter. In America, a typical shaft encoder delivers 600 or 1200 pulses per foot. Set 

the parameter to 600 or 1200. Everywhere else you are most likely concerned with 

meters. The proper setting for this parameter is then the number of pulses per METER 

that the encoder generates. 

PTD 

Yield Control - Pulse Train Delta, trip point 

This allows some error in the pulse train rate. For example, if the pulses are being 




generated at a rate of 6030 per minute, which is 100.5 per second, and we count pulses 

every second, then we will count 100 for one second, 101 for the next, then 100, then 101 

and so on. This "error" could cause adjustments to occur when no adjustment is 

warranted. The PTD parameter specifies how many over or under pulses have to 

accumulate before adjustment occurs. In the above example, if 6030 per minute was 

what we wanted, but counts came in at 101 per second, then an error of 30 would 

accumulate in 1 minute. The PTD parameter set to 00030 would cause a correction to 

occur at this level of error. The default value of this parameter is 00060 (20). 

MPO 

For Micro Blender air driven reciprocating mixer. 

MPO sets the timing, in tenths of seconds the clockwise and counterclockwise timing of 

the mix blade. MPO 00010 is 1 second for each direction. 

LIQ 

For LIQUID COLOR applications using dual pumps / drums. 

Liquid Color users generally want the current container of color to run completely out 

before switching to a new container. Switching early requires the transfer of the unused 

portion to the next container. This feature allows a standby container to be in place and 

ready, and instructs the blender to switch to the backup container as soon as the first 

container runs out, as detected by the lack of weight after a dispense. The default setting 

is LIQ 01011, which directs that component 10 is the normal output, and 11 is the 

component to switch to. Outputs 10 and 11 must first be prewired to an outlet that is 

added to the side plate of the controller. Two additional air solenoids are also added to 

drive liquid pumps that require air for operation. 

When conventional pumps are used, two pumps must be present, each connected to a 

drum of color. Both would have to be plugged into the two outlets on the duplex 

receptacle on the front of the controller. The parameter would be set to LIQ 00506, which 

is to say that the "additive" outlet (output 6) is designated as the back up output for 

COLOR (which is output 5). 

Other arrangements are possible, but require some wiring. 

MCT 

Monitor Cycle Time – For Throat Mount Applications Only 

This parameter acts as the ultimate fail-safe precaution. When used, it monitors 

sequential cycle times, and alarms if a cycle time exceeds the previous cycle time by an 

amount that is not consistent with proper operation. This provides a means to detect 

mechanical failures such as a sticking valve or weigh bin gate. When set to 00000, this 

parameter is not active. When set to MCT 02060, an alarm will occur when either a cycle 

time is double (02xxx) the previous time, or exceeds it by 60 (xx060) seconds. At poweron 

this alarm is always set off and disabled. Once smooth running is established, the 

alarm is enabled. Smooth operation is established using the same logic that Extrusion 

Control uses. If the alarm is activated, the display will say (TIME OUT). Press the alarm 

silence button to reset the alarm. A new cycle will also reset the alarm. If another alarm 

is currently active (material not dispensing for example) then this Monitor alarm is ignored 

or reset. 

G2F 

G2 Totals Collection Alarm 

The G2F parameter is used in conjunction with the G2 Software or the Get Totals 

command. The Get Totals MLAN command can be sent with either a command code of 

16 or 17. If Get Totals used command code 16, an internal flag in the controller is set 




indicating the totals have been collected for this cycle. If the G2F Parameter is on, the 

blender will stop running cycles and alarm because the flag had not been set, indicating 

the totals had not been collected for the previous cycle. At that time the "Get Status" 

MLAN protocol command will return an alarm status of 26. 

XMO 

Maximum Extruder Output (or MXO) 

For Extrusion Control, this parameter stores the extruder throughput rate that can be 

expected when control voltage is set to it's maximum output of 10 volts. On start up, 

before the unit has time to learn the correct voltage/throughput relationship, this 

parameter is used as a starting point. Having this value allows the customer to switch to 

Throughput mode right away; no need to wait several cycles. XMO is adjusted and 

corrected frequently by the software to match your process. The only time it is zero is on 

the very first start up of the system. XMO is the rate in pounds per hour, or kilos per hour. 

LTP 

Loss In Weight Trip Point 

For Extrusion Control, Yield Control, when a Loss In Weight station is part of the system, 

an adjustment "trip point" must be specified. This is the total accumulated error that is 

required to cause an adjustment to the learned rate. This is the equivalent to the XTP 

parameter, which is explained earlier. The last 3 digits are a percentage in tenths (xx.x) of 

the total batch that is being monitored. If the system is filling the Loss In Weight bin to a 

total weight of 10,00 grams, for example, and allowing it to drop to 4000 grams, for 

example, before refilling, then the batch is 6000 grams. If LTP is set to 00010, then this is 

1 percent of 6000, or 60 gram trip point. See XTP for more explanation of trip point. 

LLF 

Loss In Weight Low Level Fill 

Value in grams that will cause the fill valve on the Loss In Weight system to open and 

begin to fill. This parameter is set automatically by the *22 LIW Model Selection. 

HLF 

Loss In Weight High Level Fill 

Value in grams that will cause the fill valve on the Loss In Weight system to close and 

stop the fill process. This parameter is set automatically by the *22 LIW Model Selection. 

RLO 

LT1 

LT2 

Lowest Dump Rate (Grams/Second) 

Lower SETTING limit for REGRIND (0xxx.x). 

_SE parameters SET UPPER LIMITS to the thumbwheels. For color and additive, lower 

settings may help ensure expensive material is not wasted. 

RLO sets a LOW limit of 5 percent to the REGRIND setting. 

Loader Timeout #1 

Loader Timeout #2 

LT1 and LT2 (set ONLY if your controller is modified to control a loader) 

The LT1 and LT2 parameters are normally set to all zeros, indicating that this feature is 

not present on your system. 

If you have additional outputs on your WSB controller for driving a loading system, then 

this parameter should be set to some number indicating how many seconds you will 

attempt to load before sounding the ALARM. A sensor input to the controller tells the 

loader to load. When the sensor is covered the loader stops. If the sensor is not covered 

within the specified number of seconds, the strobe light and the beeper are activated and 




the display flashes (LOADER 1) or (LOADER 2), depending on which one has the 

problem. 

The LT1 and LT2 parameters specify this delay time before alarm. 

All circuit boards have provision for connecting level sensor inputs for 2 loaders. When 

this loader option is being used, uncovering level sensor 1 will cause pin G (7) of the eight 

pin Amphenol plug to be energized. This can be used, through a relay, to drive a loader. 




COMPONENT PARAMETERS (12 Groups of 13 parameters each) 

_TY 

Designates material type for this component 

_TY is the number that designates if this Component is used and what material 

TYPE it is. Material TYPES are REGRIND, NATURAL, ADDITIVE, or NOT USED. 

This parameter is stored as a 5 digit number but displayed as a three letter word: 

OFF = Component NOT USED, 

REG = REGRIND, 

NAT = NATURAL, 

ADD = ADDITIVE. 

Use the key to toggle through these four selections. 

(All other parameters require input of a 5 digit number.) 

The WEIGH SCALE BLENDER handles each DIFFERENTLY in the MATH routines. 

REGRIND (PERCENT OF MIX) 

Those components that you designate REGRIND will be added as a PERCENT of the 

ENTIRE MIX of material. 

NATURAL (RATIO TO EACH OTHER) 

Those components that you designate NATURAL will be added in the proportion that you 

specify them to each other. Their actual percentage of the mix will depend on how much 

Regrind is specified and how much Additive is specified. 

ADDITIVE (PERCENT OF ALL NATURALS) 

Each component designated ADDITIVE will be added as a percentage of all the 

NATURALS added together. 

If you think of your mix as a RATIO OF WEIGHTS, for example, components 1, 2, 3, 4, and 

5 are to be mixed at 100, 50, 5, 20 and 7 pounds respectively, then you may wish to specify 

ALL components as NATURALS. In this way weights may be entered just as listed. They 

need not add up to any particular number. Components will be dispensed to maintain the 

proper specified RATIO to each other component. 

If you wish to think of ALL components as PERCENTAGES of THE MIX, percents that 

always add up to 100, then you can specify ALL components as REGRIND and enter the 

exact percent for each. If ALL components are specified as REGRIND, then all settings 

must add up to 100. If the total exceeds 100, an error message will appear. 

However, we recommend that you specify materials this way: 

REGRIND; all the materials that DO NOT require the addition of the ADDITIVES. Usually 

this is your Regrind scrap. 

NATURAL; all the materials that are the bulk of the mix. These will be RATIOED to each 

other and will constitute the ENTIRE mix except for space needed for Regrind and 

Additives. 

ADDITIVE; all the materials that are added to the NATURALS only; color, stabilizer, slip 




agent, etc. 

_CS 

Set AUTOMATICALLY when you enter settings 

_CS parameter stores the current setting that has been entered through the 

KEYPAD, "SET" function, for this component. You could change it here, but the SET 

routine is the proper way to alter this number. 

This parameter can also be set to ASSIGN this component to one of the three 

THUMBWHEEL switches. This also is normally done in the SET routine by using 

the SET key followed by a letter key (A,B, or C). 

When set to 10000, 20000, or 30000 the component will follow the TOP, MIDDLE, or 

BOTTOM thumbwheel switches respectively. The SET routine is the proper way to 

assign thumbwheels. 

In the special case when there are four components, and two or more are naturals, 

then one NATURAL can have its setting calculated automatically, based on the other 

natural settings, so that all natural settings total 1000. This is done by setting the 

CS parameter to 40000. This allows four components to be controlled by only three 

thumbwheel switches, three assigned, and the forth calculated automatically by 

default. 

If this is a four (or less) component system, then you are using this software because 

your components are not NATURAL, REGRIND, COLOR and ADDITIVE. Our 

standard "FOUR" software handles that combination in a simpler, more 

straightforward way. See KEYPAD, STAR FUNCTIONS, *04 for a rapid way to set 

up your system for 4 or less components. 

_AL 

Sets alarm functions 

_AL Alarm FLAGS. When material runs out, or for some other reason material does 

not dispense fully, these flags will instruct the controller what to do. 

00000 = no alarm, no pause in process, no retries. This is sometimes useful for a 

Regrind dispense. 

00001 to 00009 = sound alarm after specified number of retries and continue retries 

until successful. The process will not continue until the fault condition is corrected. 

The last digit determines the number of retries before sounding the alarm. This is 

appropriate for all important and necessary components. 

00011 to 00019 = sound alarm after specified number of retries but then stop the 

retries and continue with the remainder of the cycle. The alarm will continue until the 

fault condition is corrected or until the next cycle begins. The last digit determines 

the number of retries before sounding the alarm. This would be appropriate if you 

wish to make several attempts at a dispense, such as regrind, but you wish the 

process to continue even without the component. 

00021 to 00029 = same as 1 to 9, Stop Process, Sound Alarm, but NO more retries. 




Just sound alarm and wait. Press the RESET button to clear alarm and start the 

retries again. Appropriate ONLY if you absolutely want operator intervention to 

occur when material runs low. In other words you do not want any automatic loading 

or other correction to allow the process to continue. 

The first three digits of this parameter (_AL xxx00) may be used to STOP and 

ALARM the blender if an over dispense occurs by the number of grams specified. 

For example, CAL 02004 will cause the system to STOP and ALARM if the COLOR 

dispense is 20 grams over target. (C - OVER) will be displayed. Use PAUSE (or 

POWER OFF) to reset the Alarm condition. If a printer is connected, a standard 

cycle printout will occur. 

_XT Allows a setting entry of less then 00.1 

_XT, is a number that will alter the value of the setting that you enter. The value of 

the XT parameter, is divided into the setting, thereby reducing the setting's value. 

The only valid entries are 10 and 100. When set to "00010" the decimal point is 

moved to the left one place and the setting is read as X.XX percent. When set to 

"00100" the decimal point is moved to the left two places and the setting is read as 

.XXX percent. This allows closer control where a requested dispense is less than 1 

percent. When set to "00000", this parameter has no effect. 

_SE 

Use to lock out high settings or limit access 

_SE is the upper SETTING limits for this component. This allows a reasonable cap 

to be set for each component so that an operator cannot accidentally set the controls 

to an excessively high setting. For additives, these limits will ensure that expensive 

material is not wasted. Settings that are greater than the limit are held to the limit. 

EXAMPLE: If the highest color usage in your plant is 6%, then you can enter this 

upper limit in the parameter table. Since settings are stored as 1/10's of percent 

(##.#), the parameter would be: 

_SE 00060 

Any setting above 060 is held to 6 percent. 

When a 1 is entered as the first digit of this parameter, (_SE 1xxxx), setting entries 

can only be made from the program mode. In this way access is limited to only those 

who know the password. 

_WT 

_TI 

Set AUTOMATICALLY by the CALIBRATE routine 

_WT, and _TI parameters are related to the flow rate or dispense rate of each 

material. These can be changed manually, set by the RATE CALIBRATION routine, 

or simply allowed to adjust automatically as necessary after each cycle. 

_WT and _TI are WEIGHT and TIME numbers that, taken together, 

indicate a dispense rate for the specified material (WT/TI). This rate is used to 




calculate an exact time period to dispense the required quantity of material. Both of 

these numbers are adjusted by the computer logic after each cycle as a means of 

continuously calibrating the dispense times. 

Since rate correction takes place continuously and the battery-backed RAM 

maintains the correct rate even when power has been turned off, these numbers will 

only be in error during the first several cycles after a flow rate has been considerably 

altered. 

Should there be a change in auger size, drive motor RPM, or some other change 

that substantially alters the feed rate of one of the components, the _WT and _TI 

parameters can be adjusted using the RATE CALIBRATION routine to ensure that 

the feeders dispense properly right from the beginning without waiting for 

adjustments to occur. 

These numbers are always kept at higher values. The computer will bump both 

numbers up in value by doubling them both until at least one number exceeds 

16,000. The ratio (rate) is still the same but error correction routines work better with 

higher numbers. 

_MI 

Set AUTOMATICALLY by the CALIBRATE routine and also reset 10 cycles after 

every power up 

_MI numbers are set to 80 percent of the amount of material, in grams, that can feed 

in one second based on normal valid dispense rates. A valid rate is considered the 

normal dispense rate that occurs under normal conditions with equipment 

functioning properly. When a rate lower than 80 percent of this actually occurs, it is 

assumed that an equipment malfunction or loss of material has occurred. Under 

these circumstances, normal rate correction routines are bypassed. 

EXAMPLE: For a 1/2" auger feeder with a 60 RPM motor drive, the normal 

metering rate is about one gram per revolution or 1 gram per second. Since the _MI 

number is expressed as tenths of grams, 80 % of this is expressed as: (_MI 00008) 

It is safe to use a _MI number that is too low but NOT safe to use 

a number too high. Error correction routines will not work when 

this number is too high. 

Power-up always resets _MI to 00001. After 10 cycles have occurred without retries, 

software will enter a corrected number. An exception to this is when the _AL (Alarm) 

parameter is set to 0, the MI parameter is left unchanged. RATE CALIBRATION 

also sets the _MI parameter. 

_NC 

Changes itself automatically over time 

_NC is the allowable GRAM error within which NO flow rate corrections are made by 

the software. Gram weight errors that are equal to, or less than, this number will be 

accepted and no error corrections will take place. Since no equipment is perfect, we 

must accept that a certain range of error is normal. To make corrections within this 




range only adds an additional error due to hunting, and broadens the error range. 

This parameter is adjusted automatically by the software according to the actual 

conditions of the metering. 

This number has been set based on our experience with the dispense devices. If, 

over time, the computer finds that the number is too large or too small, it will 

automatically adjust it to match the actual conditions that exist with your equipment. 

These adjustments occur in increments of 1 or 1/10 gram and occur only once every 

20 cycles. A change is made only if needed. Checking this number from time to 

time will indicate the normal error range that is occurring with each dispense device 

on your unit. 

If you manually set this number to a very high value, you will effectively eliminate all 

error correction attempts for the component. Gradually, over several months, the 

software will adjust this number back down. If you wish to defeat a component's 

error correction routines permanently, you may set NC to (_NC 29999). The 

software recognizes this number as special and will not change it. This high setting 

eliminates error correction attempts for this component. The component is still 

weighed, and retries still occur if short, but the timing of each dispense is based only 

on previously learned rates and never adjusted from new experience. A very small 

dispense in a high vibration environment may actually be more consistently accurate 

if no adjusting occurs. 

_PT 

For augers and micro pulse devices only 

The _PT parameters will cause the first try dispense to be a percentage of the full 

target weight. For example, with component 4 set to (4PT 00090), the first try will be 

90 percent of the full target amount. Retries then occur, but each will target only 50 

percent of the remaining requirement. A series of progressively shorter retries 

should be expected, until the retry parameters are satisfied (RP and RD). The _PT 

parameter is most effective for slow dispense devices, like augers. When setting 

_PT, also set the _RP parameter to 00001. This forces retries up to within 1 percent 

of target, instead of 10, improving accuracy. 

_RP 

_RD 


_RD is set AUTOMATICALLY by the CALIBRATE routine 

These two parameters determine the dispense shortage error that is be acceptable 

for each component. 

_RP is the shortage expressed as a PERCENT of the target dispense weight and 

_RD is the shortage expressed in GRAMS. These parameters are used together, 

either one will force a "retry". 

A "retry" is an additional dispense that is calculated to add the amount of material 

that is short. This comes into play only when the amount dispensed is less than 

expected. 

Retries will occur until the difference between the required amount and the metered 




amount is equal to or less than the _RP percent difference AND the _RD weight 

difference. 

These numbers dictate just how close to perfect the dispense has to be before going 

on. If the dispense overshoots the target, then the process continues. These 

parameters only control the degree of weight SHORTAGE that is acceptable. 

The _RP parameter is important when SMALL DISPENSE requests for color or 

additive are made. Large PERCENT errors are more likely to occur when very small 

dispenses are requested. 

The _RD parameter is important when LARGE DISPENSE requests for color or 

additive are made. Large GRAM weight errors are more likely to occur when very 

large dispense percentages are being requested. 

Depending on the accuracy of the metering device, a certain amount of hunting is to 

be expected from one dispense to the next. Allowing the software to stop trying 

when it gets sufficiently close to the target results in more perfect average 

dispenses. The mix chamber and the barrel of your process machine average out 

the small errors that occur from cycle to cycle. If no shortage is ever to be allowed 

then these parameters can be set to prevent any shortage from occurring. This will, 

however, cause an overall error on the plus side. 

Remember that EITHER ONE of the two parameters listed here 

will cause retries to occur. BOTH parameter conditions must be 

met before the process will continue, with one exception: If the 

ALARM parameter (_AL) is set to 00000, indicated that you do 

not want the process to stop, then these two RETRY parameters 

will have no effect. The first dispense will always be accepted 

and no retries will be made. 

_LA 

Change if you change metering device 

_LA is the lag TIME before dumping actually starts. This lagtime is the time it takes 

for the dispense system to mechanically respond to the controller's signal to start. 

Lag time is automatically added to all dispense times. 

Changing the means by which a device is operated such as using a different 

diameter air cylinder, or a different drive system for an auger feeder may require a 

change in this parameter. 

These parameters represent the number of interrupts (time) that pass before the 

feeder or dispense system actually begins to dispense. There are 244 interrupts per 

second. To determine these times, use the TIME dispense function in the Manual 

mode (KEYPAD instructions). 

Following the instructions given in the KEYPAD portion of the manual (TIME key), 

start with a dispense time of 1 (001). Try successively higher time numbers until 




some movement is noted in the mechanical device and a minimum amount of 

material IS dispensed on each try. This is the MINIMUM lag time number; the lowest 

number that DOES cause some movement and DOES result in a minimum dispense. 

Add 5 to this time period and enter as the lag time. Lag times that are too short can 

cause problems. That is why the MINIMUM lag time determined above should be 

increased by 5 as a safety factor. 

These numbers are preset at the factory for the equipment we have supplied. When 

a dispense of only a few grams is required, the _LA number is very important. Too 

small a lag time will result in no dispense at all because of inadequate time for the 

device to operate. Too large a number may result in over dispenses when very small 

amounts are called for. Since too small a number may stall the process, always add 

5 to the minimum as a safety. 

Typical LAG TIMES are: (minimum time plus five) 

15 - for an AC motor being powered through a relay. 

10 - for a 1" air cylinder sliding a dispense valve. 

127 - for a MAGUIRE automatic speed controller. 

_PO 

For Micro Pulse devices only 

_PO sets the ON and OFF time of the specified device during the time period that 

the device is operated. This results in a "pulsed' output. This is used in combination 

with a "micro pulse" equipped slide gate. Set to 00000 for normal operation. Set to 

00101 for pulsed operation. The first three digits (001xx) controls ON time in tenths 

of seconds. The last two digits (xxx01) controls OFF time. Larger numbers produce 

slower dispense rates without any increase in accuracy. Smaller numbers may not 

allow enough time for the slide to shift fully. 

Pulsed Output may also assist in dispensing regrind and some powders when these 

materials tend to bridge. A parameter of 00501 will produce a 1/2 second open time 

(5/10 seconds), a long enough time to allow a significant dispense, followed by a 

1/10 second close time, just enough to close the gate fully. The rapid gate 

movement may help in keeping material flowing.

PARAMETER section.

Changing Parameter Settings 

To change a PARAMETER, the sequence of keystrokes is as follows: 

Making Changes to Parameters - Keypad Sequence: 

Switch the STOP END OF CYCLE switch DOWN: 

Turn POWER ON. Wait 5 seconds, until display says ( x) 

Press 




To alter a PARAMETER: 

Press 

Press repeatedly until the parameter you want is displayed. 

If you accidentally pass it, use the * key to back up. 

With the proper parameter displayed, enter the NEW number. 

Enter 5 digits; use leading zeros if necessary. 

For correct entries, follow specific directions given in the 

PARAMETER section. 




Press Display will say: ( P x) when settings are complete. 

Additional information can be found in the KEYPAD section. 




Saving Parameters in the EEPROM 

If the changes you have made are PERMANENT, SAVE them in EEPROM. 

Sometimes during normal operation, electrical noise or RF (Radio Frequency) noise will corrupt the processor 

memory. It may be necessary to do a CLEAR to fix this problem. 

A "CLEAR" will clear all data from memory and replace it with information stored in the EEPROM. 

So it is a good idea to have an exact copy of RAM stored in the EEPROM for just such an emergency. 

To copy and SAVE all system parameter information into the EEPROM, the sequence of keystrokes is as follows 

Save Parameters Keypad Sequence: 

Press 



Press 



Wait: when done, Display will say: (P x) 


With this done, all correct Parameters may be restored from EEPROM to RAM at any time by doing a CLEAR. 

If software related problems should develop later, RETRIEVE this correct copy of the parameters from the 

EEPROM. This clears corrupted data from RAM and corrects most software problems.

SECTION 3 - PRINTED OUTPUTS 

Monitoring System Accuracy 

*54 - Cycle Printout Information 

The best way to monitor system accuracy is to connect a printer to the printer port and turn the printer flag ON 

(KEYPAD section, *54). The printer will then automatically print full output information after every cycle. 

When the printer flag is ON, the controller will output a single heading line at the top of each page and 4 

information lines to the printer at the end of each cycle. This adds several seconds to each cycle time. To turn the 

printer flag on:

Interpreting the *54 Cycle Printout 

10 or 20 cycles of data can tell a lot about the performance of your blender. The following will help you interpret 

the data. 

A single cycle printout looks like this: (dashes ---- added for clarity of spacing) 

----------- ------------ ------------ ------------ ------ 

**1 R20.0** **2 N 100** **1 C 04.0** **1 A 04.0** TOTAL 

* 11/10/01 * *16:17:53 * RECIPE 0000 **ID# 051** **WO 00000* OPR000

1 ST DISP,TIME 0.0 0.0 1908.3 469 77.6 1826 0.0 .00 22 

DEFINITION OF EACH LINE 

The TOP-OF-PAGE heading: 

----------- ------------ ------------ ------------ ----- 

**1R 20.0** **2 N 100** **1 C 04.0** **1 A 04.0** TOTAL 

Prints as a heading to each page, or once every 10 cycles. This serves as a heading over four columns of material. 

Additional lines will print for additional components as necessary, printing only those components turned on. Thumbwheel 

setting and material type is shown for each. If a thumbwheel setting is changed, a new header line will print. 




In this example, component 1 is a REGRIND; component 2, a NATURAL; 3 and 4 are set up as ADDITIVES. 

The CYCLE heading: 

* 11/10/01 * *16:17:53* RECIPE 0000 **ID# 051** **WO 00000* OPR000 

DATE and TIME this blend cycle was completed. RECIPE, ID, Work Order, and Operator numbers have no bearing on 

blender operation but aid in identifying this particular blender, and what job was running. 

DATA LINE 1: 

FINAL: DISP,% 0.0 0.0 1908.3 77.6 4.06 0.0 .00 2000.1 

For each material, each column shows the final dispensed weight of that material and its percentage of the blend. 

In this example Natural dispensed 1908.3 grams. Color dispense is 77.6 grams, 4.06 percent of the natural dispense, slightly 

over the 4 percent requested. 

The final number, 2000.1 is the total weight of the blend. It equals the sum of the component dispenses. 

DATA LINE 2: 

RATE: GR/TIME 18224 976 19993 488 12973 31232 10240 31232 9.9 

These numbers show the RATE of dispense for each material. These are the numbers that the software used to calculate how 

long to open the slide gate or run an auger, in order to dispense the required amount. This is GRAMS per Interrupts; 1822.4 

grams dispensed in 976 interrupts, which is 4 seconds. 

The final number, 9.9 grams, is the TEAR WEIGHT of the weigh bin displayed just before the cycle began. 

DATA LINE 3: 

1 ST DISP,TIME 0.0 0.0 1908.3 469 77.6 1826 0.0 .00 22 

This shows the first dispense in grams for each material and the timing of that dispense (in interrupts). 

If the first dispense weight, (data line 3), matches the final dispense, (data line 1), then no "retries" occurred. In other words, 

the software accepted the first try. If they do not match, then the first try was short and one or more retries occurred. The 

second number is the dispense time that the software calculated to be a correct first try for the dispense. 

The last number (22) is the CYCLE count, a convenient way to keep pages of data in order, like page numbers. 

Optional "BAILOUT" line: 

------------ ------------ ------------ ------------ ----- 

232 

A 4th data line (not shown in the beginning example) will print if any single dispense goes past its target weight by a certain 

value, this value set by the BER parameter, normally 200 grams. The example line shown here would indicate component 3 

overshoot the target weight after dispensing for only 232 interrupts. 

Bailouts are designed to prevent overflows of material when initial software settings, at start up, are entirely inappropriate for 

the metering device. A larger then normal error correction will occur after a bailout. 

Bailouts errors at any time other then startup, usually indicate either very poor flowing material, or excessive vibration. When 

a bailout occurs the dispense stops immediately for a weight reading. Using this information, the cycle then continues 

normally. 




Troubleshooting with the *54 Printout 

TOTAL BATCH WEIGHT: (DATA line 1) 

Check the TOTAL batch weight, (DATA line 3), to confirm the blender model. 2000 grams indicates 200 series model. 400, 

1000, and 2000 gram totals indicate models that use 3 K load cells, which means output information is in 1/10's of grams. 

4000, 9000, and 18000 gram totals indicate larger blenders that report information in full grams. Since some numbers in the 

printout do not include the decimal point, you will want to know if you are reading full grams or tenths of grams. 

TARE WEIGHT: (DATA line 2) 

In DATA line 2, tear weights should be consistently within a few grams of each other from cycle to cycle. Large variations in 

the tare weight numbers may indicate excessive vibration, some mechanical interference with the weigh bin, or a faulty circuit 

board. Tare weights above or below zero are not a problem as long as they are consistently similar from cycle to cycle. 

When problems are present, tare numbers may vary by up to 50 grams. Variations of 2 or 3 grams are not a problem. 

RETRIES: (DATA line 3 and 1, FIRST and FINAL dispense) 

When FIRST time dispense, (DATA line 3), does not equal FINAL dispense, (DATA line 1), one or more retries have occurred. 

Retries are evidence of a problem that will also cause percentage errors. 

Retries may indicate possible problems; perhaps the hopper ran out of material, or the flow rate is so erratic that the first 

dispense was short for no good reason. Parameters _RT and _RP determine what shortage error is necessary to force a 

retry. 

FLOW RATE NUMBERS: (DATA line 2) 

Check the RATE numbers, (DATA line 2), to determine each dispense device. 

In the example above: 

In the component 1 column, 18224 and 976 translates to 1822.4 grams in 4 seconds (244 interrupts = 1 sec). This is 455.6 

grams per second, typical for a regrind flowing through 3" round or 2"x3" dispense valves. 

In the component 2 column, 19993 and 488 indicate 1999.3 grams in 2 seconds, or 999.6 grams per second flow rate. This is 

a heavy natural material, not polyethylene. Perhaps Lexan or a glass filled material. 

In the component 3 column, 12973 and 31232 indicate 1297.3 grams per 31232 interrupts, or 128 seconds, for a flow rate of 

9.99 grams per second. This is a 1” auger feeder, from which we would typically expect about 8 grams per second. More 

recent auger feeders use faster motors delivering about 16 grams per second. 

In the component 4 column, 10240 and 31232 indicate a flow rate of 8 grams per second EXACTLY. Since it is exact, and 

since these two numbers are, in fact, the "default" settings from when the blender was first installed, we know that "component 

4" has never been run on this blender, or at least not since the last "CLEAR ALL" was performed. 

DATA line 3 dispense weight of 0.0 for component 4, and the TOP-OF-PAGE heading showing component 4 set to 00.0 

percent also confirm that component 4 is not being run. 

The following information will help you determine what devices are in place on a blender. 

Material Dispense Device: 

Approx. Grams 

per Second: 

½” Auger Feeders, Micro Pulse Valves 0.5 - 02

Regrinds are always lower then naturals. Bulk density will also cause wide variations in flow rates. 




ERROR CORRECTIONS: RATE NUMBERS: (DATA line 2) 

The RATE numbers are used by the software, each cycle, to calculate material dispense times. They are adjusted every cycle 

until flow rates stabilize. When a significant error is detected, the software adjusts the RATE numbers. 

The GRAM number is adjusted first. The TIME number (interrupts) is changed only if the GRAM number goes below 16,000 

or above 32,000 (approximately). In this event both GRAM and TIME numbers are doubled or halved to bring the GRAM 

number back to between 16,000 and 32,000. 

This serves to keep all numbers as large as possible allowing for the most accurate math, but not so large as to overflow the 

registers. 

Only the GRAM number changes from cycle to cycle, except under the conditions noted above. 

Check the GRAM number for a series of consecutive cycles. If it remains unchanged, then the dispenses are accurate enough 

to not trigger error corrections. Another possibility is that the parameters (MI and NC) that determine when error corrections 

occur are somehow out of range preventing corrections that should be occurring. 

The PRC parameter limits adjustments to 10 percent. Do not expect any single GRAM number change larger then 10 percent. 

A gradual decrease in the GRAM number indicates a slowing rate, a hopper that is becoming empty for example. A jump in 

rate (increased GRAM number) occurs when the hopper is refilled. 

If Errors are occurring, but the GRAM number is NOT adjusting, check the NC parameter and the MI parameter. These 

control weather or not error corrections occur. Both are set and adjusted automatically by the software. MI is set after each 

start up, after 10 cycles have run without retries. MI will be set to indicate 50 percent of normal dispense rate expressed as 

grams per second. 

NC adjusts slowly over extended periods of running. NC indicates, in grams, the upper limit of the error in 60 percent of the 

dispenses. A high number usually indicates poor flowing material. Vibration or drifting load cells are other possibilities. 

DISPENSE TIMING: (DATA line 3) 

The second number is the number of interrupts calculated to dispense the material. If these times are consistent but the 

weight of the first dispense varies, then the material does not flow well, or consistently. Another possibility is excessive 

vibration or interference with the weigh bin. 

Excess vibration, particularly on small dispenses, may cause incorrect weight readings even though the weight dispensed was, 

in fact, correct. 

If the timing number is very small, 10, 20, 30 interrupts, perhaps this is asking too much from a slide valve. Very short times 

mean you want small amounts, but are using a high rate dispense valve to do the job. An auger, a vertical valve, a horizontal 

valve with a flow restrictor, or a smaller valve would help to improve accuracy and control. 

If the timing number is below 5, you are operating in a range were it is difficult for the blender to perform well. 

The LAG time parameter adds time to every dispense. This is to compensate for the time at the beginning of a dispense when 

the solenoid valve shifts and air pressure builds, before the valve starts to move. LAG times are always set slightly longer 

then the necessary minimum. If a calculated dispense time is very short, the Lag time that is added, while small, may 

interfere with accuracy, and cause an over dispense. 

PERCENTAGE ERRORS: (DATA line 1) 

When looking at errors of percentage of color or additive dispensed, look further. 

1. First, look for indications of "retries". Retries are evidence of a problem that will also cause percentage errors. 

When FIRST time dispense, (DATA line 3), does not equal FINAL dispense, (DATA line 1), one or more retries have 

occurred. This means the hopper ran out of material, or the flow rate is so erratic that the first dispense was short for 

no good reason. Parameters _RT and _RP determine what shortage error is necessary to force a retry. 

Inconsistent loading resulting in large variations in hopper material level can cause retries. 

Excessive vibration can also cause bad weight readings, which can cause unwarranted retries. If the BAILOUT line is 




printing occasionally, then vibration is most likely causing this. Increasing the BAILOUT parameter should fix this. 

A LAG time set too high may cause retries to overshoot their mark resulting in over dispensing. 

2. Second, look at ACTUAL weight dispensed (DATA line 1). 

Color, for example, is a percentage of the natural. In the example above, Natural is 1908.3 grams, so color, at 4 

percent of Natural, is targeted to be 76.3 grams. In fact, 77.6 were dispensed. The error is 1.3 grams, well within the 

expected accuracy of a 1” auger feeder. 

The actual GRAM error of a dispense is more meaningful then the percentage error. Mechanical devices are not 

perfect. The most we can expect from them is to operate within a reasonable range of accuracy. This range is better 

defined by an error expressed in grams, rather them percentage. 

3. Third, look at the dispense TIME (DATA line 3). 

Very short times (10, 20, 30 interrupts) indicate dispense devices not well matched to the task. Accuracy on a 

percentage basis, cycle to cycle, will suffer. This may very well be acceptable as long as overall usage percentages 

are still accurate. 

BAILOUT: (line 4) 

If bailouts occur, vibration is usually the cause and these bailouts may be causing other problems. Raise the value of the BAL 

parameter to 200 or 300 grams to reduce or eliminate unnecessary bailouts. 

Vibration may also cause throughput rates to suffer due to the added time requiring to obtain acceptable weight readings. 

Increase the WDF parameter to 2 or 3 grams, (WDF 00003) or (WDF 00030), or more if necessary. 

Parameter Settings Printout 

Press (*,7,7) to print a copy of all internal parameters. A printer must be connected and ready. Up to 13 lists will print, a 

General list and 12 component lists. Only components that are turned "on" will print. Four columns will print, RAM; ROM; 

200 and 900 series tables; and EEPROM. Identifying headings print above each column. 

Load Cell Calibration - Printout Verification 

Press (*,8,8) in Program mode to force a printout of the display on the controller front. DATE, TIME, Machine number, and 

display will print: 

Date: 11/09/93 

Time: 17:22:01 

Machine number: 002 

Display Readout: P 500.0 

This is useful for obtaining printed verification of load cell accuracy for ISO and other international quality program rules. 

The recommended procedure is: 

1. Place the unit into the Program mode. 

2. Press *88 for printout of empty bin TARE weight. 

3. Place a KNOWN CERTIFIED WEIGHT into the weight bin. 

4. Press *88 again for printout with the weight added. 

5. The different between the two weight printouts should equal the KNOWN CERTIFIED WEIGHT. 




Special Tests - Printout Verification 

Using the *54 flag the following tests can be made: 

If you are running these special tests in the MANUAL or PROGRAM mode, a printout will automatically occur after each test 

provided the PRINT flag (*54) is turned on. 

Special tests that produce printouts are TIME or CALIBRATE. 

TIME (See KEYPAD, TIME; and PARAMETERS, _LA, for more information) 

The TIME function is to determine lag times of different metering devices. It also allows testing of device repeatability. The 

single line printout looks like this:

key: 

component number 

dispense time (in interrupts; 244 = 1 sec.)

CALIBRATE (See KEYPAD, CALIBRATE for more information) 

The CALIBRATE function allows the controller to rapidly learn the flow rate of the device. It automatically sets the WEIGHT 

and TIME parameters that determine metering rate, and the MINIMUM RATE parameter. For more information see 

PARAMETERS, _RA, _TI, and _MI. The single line printout looks like this:

Material Usage Printout 

Pressing the VIEW key followed by the * key will cause all material usage totals to be printed. The (*54) flag need 

not be on. These totals are since the last time printed, and since the last time cleared. 

Setting the PRT parameter to a time interval number may periodically, and automatically, print this same

A line is printed for each active component. Each line shows component number, type, setting, grand and current 

totals. 

The GRAND totals will continue to grow until they are intentionally cleared. This is done by the *00 routine, or 

pressing 00 within 5 seconds after printing these totals. 

The CURRENT totals are since the last time totals were printed. The date and times are given for LAST 

CLEARED and for LAST PRINTED. 

The percentages given for "R" types (REGRIND) are percentages of the total mix. Percentages given for "A" 

types (ADDITIVES) are percentages of all the "N" types added together. Percentages given for "N" types 

(NATURALS) are each component's percentage of all the "N" types added together. 

The POUNDS PER HOUR is calculated using the total material dispensed from the CURRENT column, and the 

time difference between the CURRENT time and the LAST PRINTED time. 




SECTION 4: TROUBLESHOOTING 

What To Do 

1. If you are reading this section, you are having problems. To locate and correct the problem we suggest that you take 

the following steps: 

2. Start by reading the WIRING CONSIDERATIONS section. Even if the system worked well for a time, dry weather or 

increased plant electrical noise can cause new problems. 

3. Then follow the CHECKOUT procedure in the front of this manual. If anything does not work right, read the 

diagnostics section that follows it. 

4. Read the section on NORMAL OPERATING SEQUENCE to be sure you understand what it is supposed to be doing. 

If you are still unsure as to how the software logic works, call us. 

5. Read the list of TYPICAL PROBLEMS that follows on the next page. 

6. Read the section on VERIFYING LOAD CELL function to be sure that the load cells are operating correctly. 

7. For difficult problems we can provide the most help if we have a printout of the PARAMETER table (KEYPAD, *77) 

and 2 pages of cycle-by-cycle printout (KEYPAD, *54). (See PRINTED OUTPUTS section) 

To Print the PARAMETER Table - Keypad Sequence: 

Press

Display will say: (PRINTING) 


To Print the CYCLE BY CYCLE information during Operation - Keypad Sequence: 

Press 


Press 

Press 

Display will say: (PRNT OFF) 

Display will say: (PRNT ON) 



Now run the blender normally until you have collated 2 pages of Cycle-by-Cycle printout and then fax this with the 

PARAMETER Report directly to your local Maguire reseller with a short cover note explaining your process, how the blender 

is located, if any changes have been made recently and what problems you are experiencing now. 

8. Try a CLEAR. Turn power off. Hold the "CE" key down and turn power ON. Display will say (CLEAR). 

9. As a last resort, do a CLEARALL, (see CLEAR ALL section) 

A list of TYPICAL PROBLEMS follows on the next page. 




Typical Problems 

These problems are based on phone calls that we have received from Weigh Scale Blender users. 

1. The display does not read close to zero when power is turned on, bin empty (plus 

or minus 10 grams). 

• The load cells are not plugged in. 

• The weigh bin is not resting properly and freely in its platform or the platform is not 

resting properly on the bolts that protrude from the load cell enclosures. 

• The controller was never calibrated for these load cells or you just did a CLEAR ALL. 

In this case it will most likely be off by several hundred grams. See LOAD CELL 

CALIBRATION. 

• The load cells are damaged. See CHECKING THE LOAD CELLS 

2. The Controller "RESETS" itself for no reason. This indicates electrical noise or 

voltage spikes disrupting the processor. 

• See WIRING CONSIDERATIONS, ASSEMBLY section. 

3. The ALARM is flashing and the display shows a weight above 100 or below -50 

grams. If above 100, the Weigh bin dump valve keeps opening and closing every 6 

or 7 seconds. 

• There is material in the weigh bin that will not dump out. 

• The dump flap may be stuck. 

• The load cells are hung up or obstructed. 

• The load cells are out of calibration. 

• Incorrect grounding is causing wide load cell readouts. 

4. The VERY FIRST DISPENSE does NOT take place. After a few seconds the ALARM 

begins to flash. The display says (N x.x) and is flashing. 

• The air supply is not connected or the pressure is set too low. 

• The Natural solenoid is not connected properly. 

• The 1/2 amp panel front fuse is blown. 

• The NATURAL slide gate is jammed. The cylinder mount may be bent. 

5. The NATURAL dispense valve continues to dump repeatedly even though the 

weigh bin has filled to overflowing. The weight reading is still below 2000.0 grams. 

• The weigh bin is not free to move. 

• The load cells are jammed. 

• The load cells are damaged. See CHECKING THE LOAD CELLS 

6. The system operates but always needs MANY RETRIES to complete a dispense 

and never seems to "learn" the proper dispense rate. 




• Vibration is causing frequent "bailouts" causing large swings in rate adjustment. 

Increase the BER parameter. 

7. The THUMBWHEEL SWITCHES do not seem to be controlling output. One or more 

LEDs (bottom row) are on all the time. 

• Someone has LOCKED IN a setting using the keypad. See KEYPAD, PROGRAM 

MODE, SETTING. 

• The _SE parameter is LIMITING the thumbwheel switch setting. See KEYPAD, 

PROGRAM MODE, and PARAMETERS, _SE. 

8. Occasionally, the system gets STUCK doing retries of a component but the retry 

time is so short that nothing gets dispensed. 

• The LAG TIME parameter is set for too short a time. See KEYPAD, TIME, and 

PARAMETER, _LA. 

• A valve is sticking closed. Check for free operation when air pressure is removed. 

9. The system USED TO WORK but now it does unexplainable things. 

• Static or a voltage surge has altered RAM memory. Do a CLEAR or CLEAR ALL. 

See "CLEAR" RESTART or "CLEAR ALL" RESTART. Then do a LOAD CELL 

CALIBRATION, and RATE CALIBRATION for ALL materials. 

10. The Display reads 3100.0 even with the bin empty. This is the upper limit load cell 

readout. 

• The Load Cells are not plugged in and the circuitry has drifted to the top limit. 

• The Load Cells have been overloaded way beyond their limit and are now 

permanently deflected. 

11. Dispenses from a slide gate are not as consistent as they should be. 

• The slide gate is sticking slightly. With the hopper empty, move the slide manually to 

see that it moves freely. Press up or down on the air cylinder to adjust for proper 

alignment. 

• The material does not flow very well. A bridge breaker adaptor may be required. 

12. Load Cell weight readings are not holding steady. They vary as much as 100 

grams from second to second. 

• This is static and improper grounding. See WIRING CONSIDERATIONS 

• If readings drift slowly in one direction, requiring frequent recalibration, a component 

on the circuit board is most likely faulty. Call us. 

• If TARE weights are not steady, something may be physically interfering with free 

movement of the cells. 

13. At the end of each cycle the MIX MOTOR runs for a fraction of a second only. 




• The MIX MOTOR pulls a heavy amp load on start up. If the power supply is not 

adequate (like when using an extension cord), the voltage will drop so low that the 

computer will reset and the mix motor signal will shut off. The display will show this 

by restarting as if power was just turned on. Provide a better supply of power; 

remove extension cord or use larger gage wire. 

Mix Problems 

Customers with mix problems have several options available. 

Decrease the batch size by lowering the FUL parameter value. This does two things. First, it causes the components to be 

dispensed in smaller, more frequent batches, which places more and smaller layers of material into the mix chamber. 

Second, it lowers the level of material in the mix chamber immediately after a dispense. It is critical to proper mixing that the 

mix blades reach up through the top of the material in the mix chamber during mix time. Dispensing a large batch may bury 

these blades, particularly when the process is not running at full blender capacity. A smaller batch size, while reducing 

throughput rate, will help prevent the mix blades being covered during mix time. 

Be sure level sensor is mounted in its lowest position, and increase sensitivity as much as possible. Both serve to keep a 

batch from being dispensed so early as to cover the mix blades. 

On units without flow control valves (FCA), increase the DLY parameter to as number as high as 50 percent of the time 

between cycles. DLY is the time delay (in interrupts) from the sensor being uncovered until we begin the batch. Increasing 

DLY allows the mix chamber to empty somewhat before the next batch drops. The maximum possible value for DLY is 29999 

or 122 seconds. 

You may increase the mix time at the end of each batch by changing the last two digits of the MIX parameter. If throughput is 

very high it may be better to run the mixer continuously. However, added mix time sometimes causes separation after an 

initial mixing. Different bulk densities and static electricity both aggravate this potential for separation from excessive mixing. 

If a blender is mounted on a stand over a surge hopper, there should be a FCA, automatic flow control valve, fitted to the 

bottom of the blender. This valve must be plumbed so that it is closed when the level sensor is uncovered. When the sensor 

is covered the valve opens to release material. The purpose of this valve is to ensure mixing. The FCV parameter delays the 

opening of this valve for 6 seconds. You can increase this delay time if you feel additional mixing is required before release. 

On model WSB-940, be sure the weigh bin has two baffles installed. These ensure horizontal layering (as opposed to side by 

side layering) of materials prior to dropping into the mix chamber. 

Bulk density and pellet shape differences, specifically smooth virgin pellets mixed with square higher density color pellets, can 

separate when dropped onto a sloping pile, as exists in a hopper, Gaylord, or surge bin. The light round pellets flow like water 

to the edges, while the heavier square color pellets stay put. This is difficult to correct. It is best not to drop these kinds of 

blends into large containers. 

Vacuum conveying can also separate materials of different bulk densities. Maintain high air velocity to minimize this. 

Models WSB-MB series units use an air drive for the mix blade, instead of an electric motor. 

If you are having mix problems with air drives, be sure the blades moves a full 270 degrees (3/4 turn) with each sweep. If they 

do not, try the following: 

Increase the air pressure. If the gauge pressure drops more then 5 pounds during operation of the blades, the air supply line 

is too small. 

Lower the pile in the mix chamber to reduce torque requirements on the mix blade. This is explained above. 

Increase the MPO parameter from 122 (1/2 second) to 183 (3/4 second) or 244 (1 full second). This allows more time for a 

full mix blade sweep to occur. You may also want to increase mix time from 10 seconds to 15 or 20 seconds so that, in spite 

of slower mix blade speed, the same amount of mixing occurs. 

Increasing Throughput 

A correctly sized blender should have throughput that always exceeds your process requirements. If, for some reason, your 

blender is not keeping up, here are a few ways to increase throughput. 




1. If your blender is equipped with a flow control slide gate, under the blender, this will reduce throughput up to 25 

percent. To counter this, set the "END FULL" flag on using the *44 function explained earlier. In the END FULL 

mode, blending begins even while the sensor is still covered due to flow control valve operation. 

2. If your process consumes a large batch of material all at once (such as during injection and screw return time), and 

material reserve is not adequate, you may "run out" of material for a few seconds while the Weigh Scale blender is 

making a new batch. The *44, "END FULL" function will also correct this. Here, when the sensor is uncovered, a 

completed batch is immediately available to help refill the mix chamber, providing a larger reserve to the process. 

3. Increase the FUL parameter. This sets the batch size. Larger batches increase throughput. Depending on the bulk 

density of your material, you may be able to increase batch size by 20 to 40 percent. 

4. Turn "FAST" on. This causes rapid volumetric "timed" dispenses to occur up to 4 times after each normal gravimetric 

dispense. 

5. Do not confuse "reserve" with "throughput". If your blender has a temporary problem which results in your process 

running out of material before you have time to remedy the problem, your "reserve" is inadequate. Add a surge 

hopper, or material level alarms on individual hoppers to prevent these types of problems. 

Normal Operating Sequence 

This section tells you how the system is supposed to work. If your system is not operating correctly, this 

description may help you spot exactly where the system is failing, providing a clue to the problem. 

Turn POWER ON: 

The current program version date (V=xxxxxT) is displayed for 1 second, followed by the 

check sum number (CKS xxxx), followed by a ROM check (ROM OK ), followed by a display 

of ( 0). The weight in the weight bin is now displayed. It should be 0 plus or minus several 

grams. During the first few minutes of operation, the displayed weight readings may drift 

slightly as the circuitry warms up. 

BEGIN operation: 

The unit will begin to operate if both switches on the left side are UP in the CONTINUE 

position and the SENSOR in the mix chamber is UNCOVERED. The sensor must be 

plugged into the right side of the controller. If it is not, this has the same effect as the 

sensor being covered; the unit will not run. 

If the WEIGH BIN DUMP Flap opens and closes repeatedly: 

If initial empty bin TARE weight is 100 grams or more, the weigh bin dump valve will operate 

in an attempt to empty the bin and bring the starting weight closer to zero. If the bin is 

empty but the weight reading is greater than 100 grams then something is wrong. See 

TESTING the LOAD CELLS and LOAD CELL CALIBRATION. 

If the ALARM flashes: 

If the initial TARE weight is below -50 grams the Alarm will flash and the unit will not 

operate. Go to TESTING of LOAD CELLS and LOAD CELL CALIBRATION. 

The DISPENSE sequence begins: 

If initial tare weight is within limits, between -50 and +100, the sequence will begin. 

DISPLAY during dispenses: 

During all dispenses, the component number and Type letter (R,N,A) will be displayed 

indicating which component is being dispensed. The INITIAL display is the tare weight of 

the bin. This will not change during the first dispense. After each dispense, the new total 

weight of the material in the bin is updated and displayed. 

REGRINDS first: 




If REGRIND is part of the blend, REGRIND dispenses will occur first in order of size, from 

the largest to the smallest. The letter "R" will appear in the display. After these dispenses 

an exact weight is taken to determine the space remaining in the weigh bin for the 

remaining dispenses. The total bin weight will appear in the display 2 seconds AFTER each 

dispense has ended. 

NATURALS second: 

The NATURAL dispenses occur next in the sequence. They will be dispensed in order of 

size, largest to smallest. The letter "N" will appear in the display. The exact weight of all 

NATURAL dispensed is now determined for calculating the ADDITIVE dispenses. 

ADDITIVES third: 

The ADDITIVE dispenses occur last in the sequence. Each dispense must meet 

requirements set by internal parameters or RETRIES will occur and the sequence will not 

continue. 

MATERIAL RUNS OUT: 

If any material runs out or is not enough to meet criteria set by parameters then the process 

will NOT CONTINUE past this component. RETRIES of this dispense will occur indefinitely 

until the full dispense occurs or power is turned off. The display will FLASH. The ALARM 

will sound after 4 retries. This number of retries before alarm is based on the ALARM (_AL) 

parameters. REGRIND may, or may not, be set to cause an alarm when it runs out. See 

PARAMETERS, _AL, for how to set the ALARM parameters. 

If ALARM flashes: 

More than four retries of any single component will cause the strobe light ALARM to begin 

flashing. The component that is causing the alarm will continue to retry the dispense. The 

display will blink and the first digit in the display will signify which component is causing the 

problem. To continue with the dispense sequence, you must satisfy the requirements of the 

dispense or turn power off. 

WEIGH BIN dump: 

After all dispenses the weigh bin is emptied by the final dump of the weigh bin into the 

mixing chamber. The dump valve remains open for four seconds. (DTI parameter) 

SENSOR covered: 

While the sensor is covered, the dump valve remains open to ensure the weigh bin empties 

completely. Dispensing stops. The dump valve will remain open for as long as the sensor is 

covered. This will be until the next cycle begins. 

FLOW CONTROL Valve: (optional) 

The Flow Control Valve under the mix chamber will stay closed for 6 seconds (FCV 

parameter) immediately following a dispense into the mix chamber. The rest of the time it 

opens when the sensor is covered, and closes when the sensor has been uncovered for at 

least two full seconds (based on DLY parameter). 

VERIFYING LOAD CELL FUNCTION 

Most Problems are related to LOAD CELL function. 

There are several ways to VERIFY that the load cells are functioning properly. The slightest touch on the weigh bin should 

result in a change in the readout. If this is not the case, something is wrong. When the light touch is removed, the display 

should return to its starting point. If this does not happen, something is interfering with free movement of the cell or the bin. 

Make a careful inspection of EVERYTHING around the load cells, the hanger bolts, the weigh bin tray and the weigh bin. 

NOTHING should interfere with free movement. 




It is normal for load cell readout to drift several grams over time and with different temperatures. 

Since all the component dispenses are weighed by a single set of load cells, this drift will affect 

all components equally and, therefore, the ratio of the components will remain accurate. Empty 

weight is always TARED so each dispense is accurately measured. 

The following observations will verify proper load cell operation: 

When the bin is empty, between cycles, the display should read near zero. An error of several grams is not important since 

this empty weight reading is "tared" from all dispense readings. The "empty weight" readings should be consistently within 1 

or 2 grams of each other. 

The addition of several pellets to the weigh bin should result in a change in the readout. 1 gram is about 40 pellets. 

Most load cell problems are caused by interference to the movement of the load cell. The load cell must be free to respond to 

the weight of a single pellet as well as free to move far enough to record a full 20,000 gram weight deflection. (10,000 grams 

per cell - 10K cells) 

If weight readout is very erratic check for damage to the load cell wires. Check for a pinched wire in the connector. 

An over stressed load cell will read high. The top limit is ( 3100.0) for a 200 series or ( 31000) for a 400 or 900 series. A 

load cell that was forced or pried upward too far will read ( 0.0). 

We supply and replace load cells in matched sets and we always include the mounting enclosures. You may remove the back 

plate from the enclosure for visual inspection. It is not safe to remove the load cell itself from the enclosure. To do so may 

stress the cell itself. 

To OPERATE with DAMAGED load cells in a VOLUMETRIC mode, see KEYPAD, *87, Volumetric mode. 

To RECALIBRATE the LOAD CELLS, see the HARDWARE MAINTENANCE section. 

If you suspect load cell damage or failure, see: LOAD CELL RAW SIGNAL READOUT. 

Load Cell Raw Signal Readout 

Press "CE" key to check this RAW number for several seconds. 

Load cells put out a very small voltage that varies slightly as the load cell is deflected. This voltage is converted, on the circuit 

board, to a pulse train and these pulses are counted for 1 full second to determine a weight load. The software can handle a 

range of counts from 0 to approximately 249,850. 

A properly operating set of 3 K cells will range from about 55,000 to 120,000; a span of about 65,000 from empty weight 

(weigh bin in place), to a full bin weight of 2000 grams. (10 K load cells range about 90,000 from empty to a full 9000 grams). 

The system will work correctly as long as the empty bin weight readout is between 1 and 149,248. 149,248 is the highest 

number that the software will accept for zero weight calibration (see parameters, LCZ). If the number is over this when you 

press the ZERO weight key, the display will say (ZERO LOW). 

This RAW COUNT number is converted to the proper gram readout, by the software, based on load cell calibration 

information. 

The RAW COUNT numbers are more useful in diagnosing load cell problems because they bypass the calibration math and, 

therefore, bypass any calibration errors that might have occurred. 

Press "CE" key to display this RAW number for several seconds. 

To observe this number continuously, use the *98 function in the PROGRAM mode.

A floating, drifting number usually indicates the load cells are not plugged in. 

A readout of 0 indicates an open circuit, a damaged wire or cell. 

A full-scale readout of 249,850 indicates a damaged wire or cell. 

A set of 3 K load cells will put out about 33 more counts for every gram of weight that is added. A test of sensitivity is to add a 

small weight to the bin. The RAW WEIGHT count should increase by about 33 counts for each gram added. (10 counts per 

gram for 10K load cells.) 

If you call us for help in solving a load cell problem, it is helpful if you can tell us what the RAW COUNT number is with the bin 

empty, and with a known weight in it. Pressing the CE key at any time will display the RAW COUNT number for the current 

weight. 

To OPERATE with DAMAGED load cells in a VOLUMETRIC mode, see KEYPAD, *87, Volumetric mode. 

Clear Routine 

A "CLEAR" routine is available that will clear all data, flags, and all other current information from memory. Since MEMORY 

is battery backed up, turning power off does not clear all fields. A great deal of information is intentionally held for later use. 

A "CLEAR" routine will clear all RAM data and start with the information stored in the EEPROM. This is the same data that 

existed when new or data that you may have intentionally saved earlier. All current rate calibration numbers that the unit has 

"learned" will be overwritten.

CLEAR does not clear EEPROM information but instead loads EEPROM into RAM. Load Cell weight calibration numbers are 

NOT lost. (To load EEPROM with correct RAM information, see KEYPAD, *23) 

Clear All 

Restart with Default System Settings - the same as the CLEAR, above, but EEPROM information is also cleared. 

There are only TWO times when you want to do a CLEAR ALL. 

1. When a NEW PROGRAM CHIP has been installed. New chips often have different PARAMETER table layouts. 

Information may reside in memory locations that do not match the new program. CLEAR ALL - RESTART fixes this. 

2. When all else fails. CLEAR ALL - RESTART will sometimes fix problems that the simple CLEAR routine misses.

Release the keys 

When done correctly the display will say (CLEARALL). 

If you do not see ( CLEARALL ) on the display, do it again. 

LOAD CELL calibration WILL be lost. You will have to follow the Load Cell calibration procedure given in this manual. 

Since parameter table information is lost, you will want to reenter parameters that were previously modified. See BRIEF 

EXPLANATION of PARAMETERS for a quick review of which ones might have been changed. 

Be certain that your unit displays the proper MODEL number when you turn on power. If not, see SELECTING CORRECT 

MODEL. 

CORE DUMP 

During production or between cycles, the controller can be forced to print a CORE DUMP of Memory. This is helpful to us 

when elusive problems are occurring related to non-predictable environmental problems. If you are having reoccurring 

problems, we may ask you to use this routine during production to help us diagnose the problem. 

To obtain a MEMORY CORE DUMP, have a printer connected. Press three keys at the same time; the PARA, FULL, and 

ALRM keys; bottom row: left center and right. 




SECTION 5 - HARDWARE MAINTENANCE 

Hardware Adjustments 

AIR PRESSURE 

Set AIR PRESSURE to about 80 PSI for best accuracy. However, lower pressures will 

work. If you plant air fluctuates, set the regulator to the low end so that the dispense valves 

always see a consistent pressure. Lubricated air is NOT recommended. Micro Blenders 

should be set to 40 PSI (2.7 bar). Vertical Valves used in removable hoppers on Micro 

Blenders, and 100 and 200 series blenders, are more accurate at 60 PSI pressure setting. 

LEVEL SENSOR 

Sensor position; 200 and 400 series models only: 

The sensor should protrude into the mix chamber about 1/4 inch past the inside surface of 

the stainless mounting plate. If it does not protrude far enough, it will sense the mounting 

plate itself. If it protrudes too far, it will sense the mix blade. 

Adjusting sensor sensitivity: 

1. The adjustment screw is located at the rear of the sensor. It may be protected by a 

small plastic screw like cover. You will need a very small screwdriver to adjust it. 

2. Fill the mix chamber until the sensor is about 3/4 covered. 

3. Turn screw counter-clockwise until the LED goes OFF. 

4. Then turn clockwise until the LED just goes ON. 

5. Empty the chamber and check to be sure the sensor LED does not go on when the 

mix blade passes near it. 

WEIGH BIN DUMP VALVE 

The WEIGH BIN DUMP VALVE should be adjusted to close softly. A needle valve is 

installed next to the quick disconnect so that air flow to the flap air cylinder may be 

restricted. Adjust as required for a soft close. 

SLIDE VALVES 

Slide valves must move very freely. If they seem to jam slightly as they reach the full 

extended position (closed), this may be due to the air cylinder mount being slightly bent. If 

someone has pulled down or pushed up on the air cylinder, they may have bent the cylinder 

mount. You can correct this by pressing up or down on the cylinder as required to correct 

the problem. 

If you process very hard pellets (polycarbonate and glass filled resins), your slide gate 

dispense valves may stick closed occasionally. We provide spacers that limit the full stoke 

of the air cylinder. This stops the slide from going any further then the just closed position 

and prevents jamming. Call us for information. 

INTERNAL MIX MOTOR and AUGER FEEDER FUSES 

The MIX MOTOR timed power source and the AUGER FEEDER OUTLETS are driven by 

internal solid state plug-in relays. A small 5 amp glass fuse is located to the right of each 

relay. A spare fuse is also located on the board if replacement is necessary. 




Load Cell Recalibration 

This unit was properly calibrated at the factory to match the load cells that were supplied with it. If you are going to 

recalibrate, note the following. 

Recalibration cannot be done until the Recalibration flag is turned ON. The proper sequence of keystrokes is 

given below. 

BE SURE 

BE SURE 

BE SURE 

BE SURE 

BE SURE 

the load cell plug is plugged into the side of the controller. 

the weigh bin is hanging from the load cells freely. 

the air line to the dump valve is connected as it would be 

during normal operation. (A disconnected air line adds weight.) 

Air pressure to the line is not necessary. 

there is nothing touching the weigh bin or air line. 

the bin is EMPTY when ZEROING the load cells. 

ZERO WT. must be done before FULL WT. Since changes in ZERO WT will also shift the FULL WT scale by the 

same amount, it may not be necessary to go any farther than this. 

When SETTING FULL WEIGHT, BE SURE you know the exact weight (in GRAMS) that you are adding to the bin. 

Place this weight in the bin and then press the FULL WT. key. Five dashes (FUL-----) will be displayed. 

Enter the EXACT weight in GRAMS that you have placed in the bin. The weight should be close to the designed 

full bin weight; (400, 1000, 2000, 4000, 9000, or 18000). The example below uses 2000. 

When done, there is no need to turn the Calibration Flag off. The next time power is turned off this flag will be 

reset to OFF. 

Load Cell Recalibration - Keypad Sequence: 

NOTE – This example is specific to a WSB 200 series with a 2000 gram weigh bin – please check your model to select 

correct FULL weight 

Press

Display will say: (CAL OFF) 

Display will say: (CAL ON) 



Followed by: (P 0) 

Place a 2000 (or 400, 1000, 4000 or 9000) Gram weight in the bin. 


Followed by: (P 2000.0) 

If YOUR weight is not exactly 2000 grams, then enter the ACTUAL weight that YOU use. 

Press Display will say: ( 2000.0) 

Remove weights from Weigh Bin Display will say: ( x.x) 

Actual displayed weights may be plus or minus a few grams. 

After FULL weight calibration, if the display says (BAD CELL), the weight you are using does not match the weight 

you entered, the weigh bin is not free to move, OR the load cells are bad. 




BLENDER PREVENTIVE MAINTENANCE 

There are no components of your blender that require periodic maintenance. However, over the years, 

blenders may be subjected to abuse or difficult conditions, and accuracy can suffer. To maintain 

control over the cost of expensive color and additives, you must maintain accuracy. We recommend 

that blenders be examined once a year, and all necessary repairs be made to insure continued 

accuracy. 

DISPENSE GATES 

To be accurate, gates must open and close freely, quickly, and completely. Check for wear on the 

slide gate guide rods. Check cylinder clevis adjustment for correct closing of the gate. A gate should 

close just enough to block the hole, but no further. It is best if they do not pass over the far edge of 

the opening as this might catch and jam on a pellet. Check that the clevis pin connecting the air 

cylinder is intact, not broken or worn through. Check for correct air pressure, tight fittings, and no 

damaged or crimped air lines. 

WEIGH BINS 

Check for smooth correct operation of the dump flap. Hinge points should not be worn. Gate should 

overlap the forward edge enough to prevent dribble when closed, even when closed against pellets. 

Space at the rear of the flap should allow for static build up of pellets on the rear edge of the dump 

flap without interfering with the closing of the flap. Again, if you see evidence of these problems, 

newer design parts are available to solve these problems. Check that the flap closes fully, and closes 

softly. The soft close is adjustable. 

CLEARANCES - FREE MOVEMENT OF WEIGH BIN 

Carefully examine all the parts of the weigh bin and the bin hanging bracket to be sure that nothing 

touches any fixed parts. A quarter (1/4) inch of space should exist on all sides of the weigh bin. Over 

the years, windows and guards have been added, and this has required that the weigh bin size be 

reduced to maintain 1/4 inch clearance per side. Be sure you do not have an older larger bin installed 

where windows have been added. 

A light touch of the bin should show a change in the weight readout. Remove the touch and the 

display should return to exactly the same number, plus or minus 1 or 1/10 gram depending on model. 

Only the last digit should drift, or vary, and by no more then one count. If ANY interference is 

detected, it MUST be fixed. 

MIX CHAMBER 

No bent blades. No SHARP blades. Bent blades might brake off and severally damage your process 

screw. Sharp blades are a safety hazard. Replace if mix blades are not perfect. 

The blade assembly should slip on and off the motor shaft easily. The need to use excessive force to 

remove the mixer assembly may bend the blades and they may eventually break off. Correct this if it 

is a problem. 

*77 and *54 PRINTOUTS 

After you have fixed any problems, use the *77 and *54 functions to obtain printouts and fax them to 

us for evaluation.
