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