1. Open the switches box cover
Before removing the switches cover, make sure that the cables are free by unscrewing the threaded
glands, to avoid to break the welded contacts between the wires and switches or the potentiometer
pins.
Then unscrew two fixing screws and remove the cover.
2. Release the cam fixing screws on the vertical shaft
BEFORE CONTINUE, BE SURE TO PREVENT THE PUSH ROD ROTATION! THIS CONDITION IS
ABSOLUTELY NECESSARY TO MAKE A CORRECT SET-UP. IN CASE OF ACTUATOR WITH ANTI-ROTATION
DEVICE, THE PUSH ROD ROTATION IS ALREADY AVOIDED.
3. Set up of CAM1 for switch SW1 to fix the required actuator retracted position
Gradually power on the electric motor of the actuator, until the push rod reaches the closed position
required by the application. Do not exceed the limit dimensions Lc (retracted actuator) stated on the
check sheet or technical catalogue.
In this position, the actuator length must be greater or, at least, equal to the dimension Lc.
Turn anti-clockwise the lower cam CAM1 until the lower switch SW1 is operated.
Fix the cam CAM1 by screwing the fixing screw.
