How to adjust cams and mechanical stops for both directions 

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

Clockwise mechanical stop setting

1. Untighten the nut corresponding to clockwise mechanical

stop and turn the mechanical stop 2 turns back.

2. Drive the actuator to clockwise travel limit position.
3. Get the clockwise mechanical stop in contact with output

sleeve then move it back of 1.5 turns.

4. Retighten nut to keep mechanical stop in position.

Clockwise travel limit switch cam setting

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

Clockwise signaling switch cam setting (if wired)

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

using manual override.

7. Set the cam corresponding to clockwise signaling switch.

Counter-clockwise settings

8. Untighten the nut corresponding to counter-clockwise

mechanical stop and turn the mechanical stop 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.

Perform complete electrical valve opening and closing operations. It 

is mandatory that the motor stops on the travel limit switch and

not on the mechanical stop (check available extra travel to the 

stop with handwheel).
