FLOW CONTROL ASSEMBLY: optional FLOOR STAND or VACUUM TAKEOFF ASSEMBLY: optional RED INSTRUCTION STICKERS will assist you during assembly. LIFT HANGERS are available to allow lifting of the blender with a strap or chain. Call us if you require them.

Page 9: 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"...
Page 10: Check Out Procedure & Diagnostics
As you go through this procedure, if WHAT SHOULD HAPPEN, doesn't happen, see the next section, DIAGNOSTICS, for what to check. NOTE: 100 and 200 series models (3K load cells), display all weight readings in 1/10 grams ( models (10K load cells) display in FULL grams, no decimal. On this page we show all weight readings WITH a decimal point.

When using a MICRO PULSE valve, you must set the related _PO parameter to 00101. If overall blender throughput is too low, you may increase the metering rate of each Micro Pulse device by adjusting the cylinder air flow control valves for higher flow rate.

Higher batch weights will increase maximum throughput rates. If your Regrind is very fluffy and you use a lot of it, you may find 2000 grams to be too much volume for the bin.

Both of these numbers are adjusted by the computer logic after each cycle as a means of continuously calibrating the dispense times.

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:...

DATA line 1: ------------ FINAL: DISP,% For each material, each column shows the final dispensed weight of that material and its percentage of the blend.
Page 72 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.

When a significant error is detected, the software adjusts the RATE numbers. The GRAM number is adjusted first. changed only if either number falls above 32,768, or both fall below 16,384.

+--------------------------------------------------------------------+ ¦ +--------------------------------------------------------------------+ If you are reading this section, you are having problems. and correct the problem we suggest that you take the following steps: Start by reading the WIRING CONSIDERATIONS section. Even if the system worked well for a time, new wiring or increased plant electrical noise can cause new problems.
Page 79: 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. If your blender is equipped with a flow control slide gate, under the blender, this will reduce throughput up to 25 percent.
Page 80: Typical Problems
These problems are based on phone calls that we have received from GB/WSB Autoweigh Blender. 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.

COLOR third and ADDITIVE fourth: COLOR is dispensed followed by ADDITIVE as requested by the thumbwheel switch settings.
Page 84: Verifying Load Cell Function
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.

Page 86 LOAD CELL plus WEIGH BIN TEST to verify correct operation This test is to help you determine if the load cells are working correctly, and if the weigh bin and weigh bin hanger are moving freely and registering weight correctly. Have a pad and pencil ready to write down the weight readings that appear on the display, both before and after each dispense.

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.

If you recalibrate, note the following: Recalibration can not be done until the Recalibration flag is turned The proper sequence of keystrokes is given below.
