2 CHECK BEFORE POWER UP 

ST INTELLI+ motorization systems are multi-turn actuators resulting from many years of experience in valve systems 

remote control. 

Functions to set up, check and control the actuator are included in INTELLI+. 

All settings and configurations are carried out from outside without opening the covers. 

Do not attempt to open covers so as to avoid humidity ingress in the control system. Only open terminal box cover (fig.2) 

just long enough to make connections. 

Every actuator is tested, adjusted and checked in works before delivery. It is lubricated for life and designed to operate 

in any position or location. 

MANUAL HANDWHEEL 

All ST INTELLI+ actuators are provided with an automatic declutching handwheel, with motor drive priority. Operating 

direction is normally indicated on the handwheel. 

The ST6 actuator includes a handwheel clutch button. In order to operate the actuator manually, turn the arrow of the 

button opposite the triangular sign (fig. 1) on the housing (it could be necessary to turn the handwheel by a few degrees 

to position the claws). When the motor starts, the button automatically returns to its declutched position.

a) Check the power supply characteristics. 

In 3 phase, the order in phase is not important. INTELLI+ automatically corrects the direction of rotation. 

b) Open terminal box (fig. 2), connect power and control circuitry, check wiring.

3 LOCAL CONTROL 

Local control is used to drive the actuator without the help of an external control circuit. A local selector allows to choose 

between remote or local and off. The button for local control open/close allows to operate the actuator in the appropriate 

direction. Local stop is done by a momentary rotation of the local/remote selector. 

A display gives the valve open percentage. 

20% OPEN 

A black square in right corner informs of presence of an alarm 

(see para. 16.2 how to read alarm type). 

4 REMOTE CONTROL 

Remote control of an actuator equipped with the INTELLI+ can be done from an external voltage supply or an internal 

voltage supply. 

Inputs on the board are completely isolated by opto-isolators. 

Pulse commands (with self-holding) require 4 wires connected to the customer terminal board : Common, stop, open 

and close. If the stop button is not used, do not connect the STOP wire, open (or close) contact must be maintained 

to operate the actuator. 

4.1 Dry contact control 

In case of dry contact control, a jumper must be fitted across customer terminals 31-32.

4.2 Voltage control 

Remote control can be done either in AC or DC voltage. 

For lower voltages, from 10 to 55V, use common terminal 31. 

For higher voltages, from 55 to 250V, use common terminal 30. 

Caution : never connect voltages higher than 55V on common terminal 31.

8 ADJUSTING AN ACTUATOR ON A VALVE 

The SET UP menu is used to set the open and closed positions after the actuator is installed on the valve. Setting can 

be achieved manually by selecting the open and closed positions, or automatically. In automatic mode, the actuator 

operates and stops under the effect of a load limiter at the end positions. The INTELLI+ then determines the stop positions. 

To avoid a stop under the effect of the load limiter, or choose the stop positions, use the manual setting procedure. 

8.1 Manual setting 

Select set up in the MENU and confirm by OK. 

Select closing mode in the SET UP menu and confirm by OK. 

Choose to close the valve based on torque or based on position and 

confirm by OK. 

Select close direction and confirm by OK. 

Choose the normal closing direction (clockwise, generally) and 


Select position setting and confirm by OK. 

Select valve closed ? to achieve setting in the closed position and 


When (no) is displayed confirm by OK. 

The display is as follows : 

Place the valve in the closed position either using the handwheel or 

electric control. 

Observe the closing mode selected above, i.e. close up to the load 

limiter for closing based on torque, and without triggering the load 

limiter for closing based on position. 

When the position is achieved, do a local stop to return to the menu. 

When (yes) is displayed confirm by OK. 

If in doubt, select (no) and repeat the procedure. 

Position ok is displayed. Continue by OK. 

The next step is setting of the open position. 

When valve open ? is displayed, confirm by OK. 

When (no) is displayed, confirm by OK. 

The display is as follows : 

Set the valve in open position either using the handwheel or using 

electric control. Check that the actuator will not go to mechanical stop. 

When the position is achieved, do a local stop to return to the menu. 

When (yes) is displayed, confirm by OK. 

If in doubt, select (no) and repeat the procedure. 

Position ok is displayed. Continue by OK. 

Upon completing of setting, the stroke is displayed. 

Return to control mode after confirming by OK. 

8.2 Automatic setting 

Select set up in the MENU and confirm by OK. 

Select closing mode in the SET UP menu and confirm by OK. 

Choose to close the valve based on torque or based on position and 


When close direction is displayed, confirm by OK.

Select automatic in the POSITION SETTING menu. 

After confirming by OK the automatic setting cycle starts. 

The actuator detects the end positions by triggering the load limiter 

then positions itself at mid-stroke to test its inertia in both directions 

of rotation. 

The INTELLI+ determines the 0 and 100% stop positions taking 

account of the set up closing type and the actuator inertia. 

Upon completion of setting, the stroke is displayed. 

Return to control mode after confirming by OK. 

9 POSITION SIGNAL AND POSITIONER 

Position signal 

According to the actuator equipment, a voltage or current position signal may be available. 

No setting is necessary, as the signal is set automatically when setting the 0 to 100% position. 

See para. 19 for more details. 

Positioner 

According to the actuator equipment, it may be operated in regulationfrom a control signal ( e.g. : 4 - 20 mA). 

No setting is necessary, as the signal is set automatically to the 0 to 100% position setting. 

To check positioning locally, local control must be set up from 0 to 100% in increments (see para. 10.3). 

After the setting up is completed and returning to local control mode, the display reads the opening position and the 

control in %. 

Using the blue button, increase or decrease the control % and check that the actuator follows the requested position. 

For remote control, either in automatic (e.g. : 4 - 20 mA) mode, or in on/off mode, use an auxiliary command programmed 

as AUTO/ON-OFF. 

This auxiliary command enables you to select automatic or on/off control (see para. 10.2) 

See para. 20 for more details, in particular for dead band setting, as required. 

10 COMMANDS 

See above the description of standard remote commands (para. 4). A description of additional control facilities follows. 

10.1 Remote control by single contact 

The actuator can be controlled by a single external contact. 

- Contact closed : valve opening 

- Contact open : valve closing 

The actuator must be set up as "priority to open" (see para. 10.4).

terminal 

❡ local + remote / remote : same definition as above, but local and remote control can be enabled simultaneously. 

❡ local command inhibit : the local command inhibit is remotely controlled. This command inhibits the local opening 

and closing commands, and enables remote commands, even if the local/remote selector of the actuator is set to local. 

After confirming by OK, the operator needs to decide to retain local 

stop or not. As standard, local stop and general stop remain possible 

at the actuator. To also inhibit local stop and general stop, select local 

off (no). 

After confirming by OK, the contact status must be selected for this 

command to be achieved (as described above). 


❡ open, close inhibit : this command is used to inhibit opening or closing 

of the actuator. 

For example, a main valve equipped with a by-pass valve must open 

only if the by-pass valve is already open. A by-pass valve opening 

limit-switch can then inhibit opening of the main valve as long as the 

limit-switch is not actuated.

❡ auto/on-off : for an actuator used in regulation with positioner function, 

it is possible to issue remote commands via a continuous signal 

(ex : 4 - 20 mA) or via opening/closing/stop commands. The auto/onoff 

command is used to switch over from one type of command to 

another. 




❡ ESD close, open, stop : the ESD (Emergency Shut Down) is an 

emergency remote command, which overrides all other commands. 

According to the valve operation, the emergency command will be an 

opening, closing or immediate stop. 




10.3 Local command 

As standard, the local command is self-held (a pulse is enough to achieve an opening or closing command). 

To override the self-hold feature (the opening or closing command must be held during actuation) : 



Select local command in the COMMANDS menu and confirm by OK. 

Choose (maintained) and confirm by OK. 

For local command by increments from 0 to 100 %, choose (0 - 100%). In this case, the command assumes the current 

position value and will be displayed under the position. The blue button can then be used to change the command 

value in 1% increments. 

10.4 Local stop 

In standard, it is possible to stop the actuator locally, even if the selector local/remote is on remote position. To inhibit 

a local stop when the selector is on remote position, select local stop in the CHANGE menu and choose (no). 

10.5 Open or close priority 

As standard, there are no open or close priorities. Priorities are used : 

ð to reverse the direction of travel during actuation, without the need for a stop command. In this case an open and close 

priority is required. 

ð give priority to a direction of travel : if the actuator receives 2 simultaneous open and close commands, and an open 

priority has been selected, the actuator operates in the open direction. 

ð to achieve single contact commands (see para. 10.1). 



Select priority in the COMMANDS menu and confirm by OK. 

Choose (open), (close) or (open and close) and confirm by OK. 

10.6 Fault tolerance ESD 

As standard, the protection devices are active and therefore stop the 

actuator in case of defect. 

In the case of an emergency command (see description of aux. commands 

1 or 2), it is possible to bypass certain protection devices to 

achieve operation even in the presence of defects. 



Select fault tolerance esd in the COMMANDS menu and confirm by OK.

11 LOCAL IR LINK COMMUNICATION 

The actuator is equipped with a two-way (read and write) IR link used to communicate with a laptop computer by means 

of an IR module connected to the laptop RS232 port. 

An IR kit is available for this connexion. The kit also includes the CD-ROM for the communication program to be loaded 

in the PC. 

This IR module can be clipped to the actuator window for easy communication even if the window orientation is not 

adequate. 

The cable lenght is 2 m (an extension is available as an option). 

The CD-ROM software provides on-screen access to all the INTELLI+ functions. It is also used to load instantaneously 

preset configurations and to acquire the torque/position graph of the last electrical actuation. 

For more details, see the software handbook enclosed with the CD-ROM. 

Access by IR communication is only possible if the actuator is not in menu mode. To CHANGE or SET UP, the unit 

must be set to local mode (i.e. the local / remote selector must be set to local). In this case, the IR link overrides 

control by buttons. 

After communication is established, IR (for infrared) is displayed in the upper right-hand corner of the actuator display. 

12 SETTING AND READING TORQUE VALUES 

12.1 Closing mode 

As standard, the actuator closes based on position. The settings for the actuator to close based on torque can be changed 

in the SET UP menu, however, it is possible to do so in the CHANGE menu : 


Select torque in the CHANGE menu and confirm by OK. 

Select closing mode in the TORQUE menu and confirm by OK. 

Choose on (torque) and confirm by OK. 

12.2 Setting the torque 

The actuator is delivered with a torque limiting system set in accordance 

with the order. 

If the torque limiter is triggered in operation, check : 

❡ that the valve stem is clean and well lubricated 

❡ that the valve stem does not jam in the actuating nut 

❡ that the packing gland of the valve is not too tight 

If the torque needs to be increased, and further to the valve manufacturer's 

approval, proceed as follows : 



Select torque setting in the TORQUE menu and confirm by OK. 

Select the desired setting and confirm by OK. 

Increment or decrement the value using the blue button. When holding 

the button, the digit scrolling motion is accelerated. 

Description of the torque limiting feature : 

All torque values are expressed in percent. 100 % corresponds to the 

actuator max. setting. The corresponding value in Nm is indicated on 

the actuator identification plate. 

- closing % : limits the torque during closing 

- close tight % : this option only appears if closing must be based on 

torque. In this case, the sealing torque applied to the valve seat may 

be different from the torque limiting during closing. 

- open breakout % : this option only appears if closing must be based 

on torque. In this case, torque limiting at valve seat separation may be 

different (in general greater) than torque limiting during opening. 

If setting is greater than 100%, the display reads no limitation which 

amounts to shunting the load limiter at beginning of opening. 

- opening % : limits torque during opening 



in the menu, select 

check instead of change.

12.3 Reading the measured torque values and comparing them with original torque values 

At each electrical actuation, the max. resistive torque values are measured 

and may be checked. 

It is possible to store the torque values from an actuation to subsequently 

compare them to the torque values from the last electrical 

actuation. 



Select measured torque in the TORQUE menu and confirm by OK. 

Select the desired torque and confirm by OK. 

The display provides the max. torque measured during the last electrical 

actuation. 

(nota: actuations during setting are not stored) 

If the torque values of a previous electrical actuation have been stored, 

they may be read on the next line for reference. 

Example : in the case shown above, the torque stored during an initial 

actuation was 12% and the torque during the last actuation was 18%. 

These two values can be compared to take preventive maintenance 

action, as required. 

Storing electrical actuation torque values 

To store the torque values of an electrical actuation in the menu, 

select save then choose : 

torque ➨ ref (yes). torque values marked ref then take the last electrical 

actuation torque values. In case of error, select again 

torque ➨ ref (no). The reference torque values will be restored. 

The values will only actually be stored in memory after exiting the 

CHANGE menu and validating (change ok ?). 

Torque display 

Select this option to read on the actuator display on a permanent 

basis the instantaneous torque simultaneously with the position. 

13 CUSTOMIZING REMOTE INDICATIONS 

13.1 Relays 

Signals indicating the status of the actuator are transmitted by bistable 

relays. Each relay can be set up according to a list of available 

options. As standard, the INTELLI+ is equipped with 4 bistable relays. 

3 additional monostable relays (the contact is open when the relay is 

de-energized) can be added as an option. The equipment is factoryset 

in accordance with the order. To change the setting, proceed as 

follows : 


Select signaling in the CHANGE menu and confirm by OK. 

Select the relay in the SIGNALING menu and confirm by OK. 

Choose the contact type, i.e. the contact status when no action and 


Choose the desired function(s) :

15 TIMING CONTROL DURING ACTUATION 

The INTELLI+ contains a timing module used to reduce the actuator operating speed, for example to protect a pipe 

against pressure surges. 

When an opening or closing command is sent, a timer alternately turns the motor on and off. The valve actuation time 

may therefore be very long. This time is adjustable on site. 

Settings in the opening and closing directions are independent. 

It is also possible to apply timing only on part of the stroke, and the rest of the stroke is covered at normal speed. 

The setting only consists in indicating the total desired time, and the INTELLI+ calculates the on and off times. 


Select timer in the CHANGE menu and confirm by OK. 

Select operating time and confirm by OK. 

Indicate the actuation time at normal actuator speed. 


When holding the button, the digit scrolling motion is accelerated. 


Select timer open time and confirm by OK.

Select timer close time and confirm by OK. 

Indicate the total time desired for valve closing and confirm by OK. 

To cancel the timer function : check that the timer opening and 

timer closing times are not greater than the travel time. 

To apply timing only to part of the stroke : select temporized zone 

and confirm by OK. 

In order to start opening timing at a given position only select open : 

start % and confirm by OK. Increment or decrement the value using 

the blue button until the desired position is achieved between 0 and 

100 % and confirm by OK. Proceed in the same way with the other 

values, which determines an opening temporized zone and a closing 

temporized zone. 

To apply timing to the complete stroke, check the default values : 

open : start % (0) close : start %(100) 

open : end %(100) close : end % (0)

19 USING THE ANALOG SIGNAL POSITION AND TORQUE REMOTE INDICATION 

(ACCORDING TO EQUIPMENT) 

19.1 position remote indication 

According to the equipment, the actuator can remotely indicate its position (0 - 100 %) by sending an analog signal. 

The output signals are set automatically to the actuator 0 - 100 % stroke which eliminates the need for setting the remote 

indication signal. 

The remote indication signals are fully isolated from the INTELLI+ circuits. 

The available signals are : 

4 - 20 mA, 0 - 20 mA, 4 - 12mA or 12 - 20 mA and 0 - 10 V (distinct output) 

To choose the signal variation direction and the type : 


Select position in the CHANGE menu and confirm by OK. 

Select opt position signal in the POSITION menu and confirm by OK. 

Choose the signal variation direction and confirm by OK. 

Choose the type of signal and confirm by OK. 

19.2 Torque signal 

The signal representing the 0 to 100 % actuator torque is also available in 4 -20 mA (0% = 4mA, 100% = 15 mA). 

The torque signals are fully isolated from the INTELLI+ circuits, except that the minus is common with the position 

remote indication signal. 

See electrical diagram for connection of these signals. 

20 USING THE EQUIPMENT AS A POSITIONER FROM AN ANALOG CONTROL SIGNAL

20.2 Dead band setting 

This is a factory setting, but it is possible to adjust the dead band. 

If the dead band is too narrow, the actuator may pump. If the dead band is too wide, positioning is less accurate. 

In the POSITIONER menu, select dead band % and confirm by OK. 



20.3 Fail-safe position 

With a 4-20 mA input signal, it is possible to set up a fail-safe position in case the control signal is lost. 

As standard, the function is active and the actuator remains in position in the case of signal loss. 

It is possible to choose opening or closing. 

In the POSITIONER menu, select lost signal and confirm by OK. 

Select the desired function and confirm by OK. 

20.4 Proportional pulses 

This is a control mode where the position is reached by pulses. This mode is used for relatively stable regulations allowing 

the actuator inertia to be partly compensated. The actuator is cycled more often than by a conventional command. 

In the POSITIONER menu, select proportional pulse and confirm by OK. 

Select (no) or (yes) and confirm by OK. 

21 USING FIELD BUS CONTROL (ACCORDING TO EQUIPMENT) 

The field bus interface can be used to control and transmit all data over a single line. A specific documentation specifies 

how each actuator can be addressed and provides a list of addresses for accessing each command or data. 

Fail-safe position 

In case of loss of communication, it is possible to set up a fail-safe position. 

As standard, the function is active, and the actuator remains in position in the case of a loss of communication. 

It is possible to choose opening or closing. 


Select fieldbus in the CHANGE menu and confirm by OK.

correct direction. Reversing the motor direction of rotation 

is by switching over wires 2 and 3 of the motor terminal 

strip. 

Access to the menu by means of the buttons is only possible 

in local mode, i.e. with the selector set to local, in the 

absence of a local command inhibit. Set selector to local 

and see above for checks to be performed on aux. commands 

1 and 2. 

Go to the change menu. 

Some parameters can only be checked. 

After changes have been made, select return then OK as 

many times as necessary to read : 

(change ok?) 

Confirm by OK to store the changes 

Repeat detection under correct conditions. 

This alarm does not limit actuator operation, but indicates 

intensive operation of the actuator. If the start rate again 

becomes compliant with the unit intended use, the alarm 

disappears. 

This function, set up in the timer menu is used, at the user's 

request, to increase the actuator actuation time.

24 MAINTENANCE 

All ST actuators are lubricated for life and therefore require no specific maintenance. The condition of the valve stem 

and its nut must nevertheless be checked periodically to make sure they are clean and well lubricated. We recommend 

that a programm of periodic maintenance should be drawn up for actuators that are operated infrequently. 

25 STORAGE 

Introduction 

The actuator includes electric equipment as well as grease lubricated gear stages. In spite of the weatherproof enclosing, 

oxidation, jamming and other alterations are possible if actuator is not correctly stored. 

Storage 

The actuators should be stored under a shelter in a clean, dry place and protected from constant changes in temperature. 

Avoid placing the actuators directly on the floor. If the place of storage is humid it is recommended that you connect 

and give supply to the actuator to have the heater effect. 

Check that the temporary sealing plugs of the cable entries are correctly installed. In case of humidity, use metal plugs. 

Make sure that the covers and the boxes are well closed to ensure weatherproof sealing. 

Control after storage 

Local / remote selector 

set to local or off 

An Auto / On Off command 

is present and 

inhibits positioner use 

Incorrect adaptation of 

the input signal 

The local / remote 

selector is set to local 

The input signal is 

defective 

The signal polarity is 

not compliant 

1. Storage not exceeding one year : 

Maintain a visual check of electric equipment 

Operate manually the buttons, selectors, etc ... to insure the correct mechanical function 

Operate apparatus manually 

Verify the correct grease consistency 

Follow instructions included in the commissioning instructions heregiven 

2. Storage exceeding one year : 

Long time stocking change grease consistency. The grease thin thickness on stem dries up. Remove all the old grease 

of the actuator mechanical parts and replace with new grease. 

Maintain a visual check of electric equipment. 

Operate manually the buttons, selectors, etc ... to insure the correct mechanical function. 

Follow instructions included in the commissioning instructions heregiven. 

Set the local / remote selector to remote to use the positioner. 

In the commands / aux. commands 1 or 2, check whether 

auto / On Off is set up or not as well as the contact status 

(open or closed) to perform this command remotely. Then 

check that the connection made at the client terminal strip 

does not correspond to an On Off command. 

Ex.: if the configuration is set to aux. command 1, (auto / 

on-off) and contact (c)= auto it is then necessary to establish 

a contact remotely on terminal 37 to switch to auto 

command. 

Check the configuration of the input signal in the menu and 

the setting of the switches on the positioner board (see 

para. 20.1) 

Set selector to remote 

Check the reference signal using a milliammeter connected 

in series (terminal 70) 

Check that the signal (+) is present on terminal 70.
