CAUTIONS BEFORE COMMISSIONING
Warning:
This actuator includs one compressed spring which can be dismounting only with special
tools. The control box remains accessible without having to use special tools.

ELECTRICAL CONNECTIONS AND OPERATION
• Check the power supply type.
• When the power supply is OFF, the actuator is on one of its mechanical stops.
An incorrect electric motor rotation could damage the actuator.
Then check the electric rotation direction.
• Do not energize the brake.
•
Pull down the declutch lever (when the actuator has
an handwheel).
•
Put the power on the motor and check the right
rotation direction (arrow on the motor).
•
Connect the travel limit switches and check by swit
-
ching them if they are functioning correctly.
•
After above controls, do not forget to plug (energize)
the brake.

MECHANICAL STOPS SETTING
When the power supply is OFF, the actuator is on one of its mechanical stops. To modify this position,
screw or unscrew the corresponding mechanical stop then lock the nut on the screw to keep
the position. The mechanical stops and nuts are located outside the actuator housing.
4
TRAVEL LIMIT SWITCHES SETTING
The cams actioning the microswitches are located in a block which is driven by the main shaft.
1 - Put a screwdriver in the corresponding slot of cam to set.
2 - Push slightly to engage and turn left or right according to the required cam position.
3 -
Remove the screwdriver and ensure that the button has come back to its original
position, thus locking the cam in the chosen position.
4 -
Make sure that the electric motor has stopped by the travel limit switch and not by the
mechanical stop.
Caution: Always the travel limit switches have to cut off the motor power supply before to reach
the mechanical stops.

POSITION INDICATOR SETTING
The dial indicator is fixed on a shaft. Unlock the screw and position the arrow in front of the corres
-
ponding position shown on the cover then lock the screw.

MANUAL OPERATION
In case of power failure the actuator can be used through the handwheel (only on types FQR).
Proceed as follows:
• Unlock if necessary, the clutching lever (on the side
of the actuator) by removing the padlock (optional equipment).
• Pull down the lever to engage the handwheel.
• Turn the handwheel to drive the valve.
Warning:
When the lever is in a manual position, no fail-safe
action is available.
To bring the actuator back into its safe position, place the lever
in its original position. The remaining energy of the spring will
allow an automatic come-back in the safe position.
