5 ELECTRICAL CONNECTION AND TESTS

To perform electrical wiring, please refer to the wiring diagram

supplied and follow the terminals' numbering.

!

Make sure not to wire AC supply on A, B, C terminals or DC supply

on 1, 2, 3 terminals, that will damage the board.

Checking after wiring

Once the actuator wiring is completed, the following points must be

checked:

1. Make sure that power supply voltage matches information on

the sticker on the side of the actuator.

2. Check that all connectors or cable glands are correctly

tightened.

3. Move the valve using manual override to an intermediate

position.

4. Electrically operate opening and closing travels and check that

the actuator rotates in the right direction and stops at the

desired position.

If any fault is detected at this stage, please check all wiring.



Never use a powered rotary equipment on manual override to

operate the actuator.

6 TRAVEL LIMIT SETTINGS

The actuator is factory-set for a 90°travel.

It features 2 devices to limit the travel:

• Cams trigger switches to switch off power at an end position or

to signal a position.

• Mechanical stops mechanically block rotation to protect the valve

in case of over-travel. They must not be used as travel limits.

Setting a single cam

The cam rotates as the

output shaft and triggers a

switch by pushing on its

lever.

Cams orientation are factory

pre-set, yet you can still re-

adjust them upon the

installation if necessary.

How to adjust a single cam

At the desired position of the actuator output:

1) Turn the setting screw of

the corresponding cam

with a flat-head

or a

Phillips-head screwdriver.

The cam disk is then turning.

2) Set the cam disk until you

hear a click from the

switch. It

indicates the

triggering of the switch.



Make sure the cams contact the switch according to their proper

direction of travel, otherwise you could damage the switch.

Travel limit cams and signalling cams

On AQL actuator, you have 4 cams

with 2 different functions:

• Travel limit cams cut motor

power supply when they

trigger the switches

corresponding to an end

position.

• Signalling cams are not wired

by default. You can use them

to indicate when the

actuator gets close to an end

position.

Signalling cams must be set to reach their corresponding switch

before the travel limit cams do.



If the actuator is supplied mounted on a valve, following

settings should have been performed by the valve supplier.

Setting cams (AQ1L & AQ3L)

AQ1L & AQ3L have fixed mechanical stops. Travel limit settings are

done by cams only.

How to adjust cams for both directions

1. Drive the actuator to clockwise travel limit position.

2. Set the cam corresponding to clockwise travel limit switch.

If the clockwise signalling switch is wired:

3. Drive the output slightly in the counter-clockwise direction

using manual override.

4. Set

the cam corresponding to clockwise signalling switch.

5. Drive the actuator to the counter-clockwise travel limit

position.

6. R

edo settings steps 2 to 4 for counter-clockwise direction.

Setting cams and mechanical stops (AQ7L)

AQ7L has both mechanical stops and cams that can be set.

Setting travel limits

The mechanical stops limit

the actuator travel.

Fine adjustment of the stop

screws position is possible

within a limit of ±2°

maximum. These screws are

located in the lower section

of the actuator.

The actuator stops on open

or closed position when the

travel limit switch is

tripped.

How to adjust cams and mechanical stops for both directions



One turn of the adjustment screw = 4° angle variation at the

actuator output.

1. Untighten the nut corresponding to clockwise mechanical

stop and turn stop screw 2 turns back.

2. Drive the actuator to clockwise travel limit position.

3. Get the clockwise stop screw in contact with output sleeve

then turn it back of 1.5 turns.

4. Retighten nut to keep position of mechanical stop.

5. Set the cam corresponding to clockwise travel limit switch.

If the clockwise signalling switch is wired:

6. Drive the output slightly in the counter-clockwise direction

using manual override.

7. Set the cam corresponding to clockwise signalling switch.

8. Untighten the nut corresponding to counter-clockwise

mechanical stop and turn stop screw 2 turns back.

9. Drive the actuator to the counter-clockwise travel limit

position.

10. Redo settings steps 3 to 7 for counter-clockwise direction.

7 PROPORTIONAL ANALOG COMMAND (OPTION)

The proportional analog

command allows to drive

the valve to intermediate

positions.

Board is factory pre-set.

Perform the electrical

wiring according to the

wiring diagram of the

actuator.

Setting up positioner board



Take care that the board is supplied during setting process.



The actuator is delivered with the proportional analog command

already installed, and the settings have already been done at

our factory.

Only go through the setup procedure below if you had to adjust the

mechanical end stops positions. Board setup is fully automatic.

How to run the board setup

1. Press for 5 seconds on the SW1 push button located on the

board.

The yellow LED is blinking while the setup is in progress and

is remaining lit when the setting is completed.

2. Control the setup by performing some clockwise and counter-

clockwise operations.

8 TORQUE LIMITING DEVICE

In case of excessive torque on the actuator, a torque limitation

system shuts down actuator.

A LED behind switch board is lighting up when this protection is ON.

How to re-start the actuator if torque limiter went off

1. Switch power supply off.

2. Check if the issue comes from valve (stiff point or jamming)

or mechanical stops (over-travel or wrong mechanical stop

settings).

3. Fix the issue.

4. Switch power supply on and electrically operate actuator in

both directions.



LED remains lit a few seconds after power supply is switched off.

Wait those few seconds before switching power supply on again and

operating actuator.
