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 blade or a

Phillips screwdriver.

cam disk is then turning.

2) Set the cam disk until you

hear a click from the

switch. It indicates the

trigger of the switch.

Cams and mechanical stops setting

On AQ switch actuators, both cams and mechanical stops can be set.
The actuator stops on open and closed position when the travel limit

switch is tripped.

Travel limit settings

The mechanical stops (

1

: counter-

clockwise

2

: clockwise) 

avoid over-travel in case of 

handwheel operation. 
They can be set on the actuator or 
on the gearbox if a gearbox is

fitted on the actuator.
Fine adjustment of the stop 

screws position is possible 

within a limit of ±

maximum. These screws 
are located on the lower side of the actuator.

Take care that cams get to the lever according to its inclination 

direction, otherwise you could damage the switch.

If the actuator is supplied mounted on a valve,

following settings should have been performed by the

valve

supplier.
