6 TRAVEL LIMIT SETTINGS
The actuator is factory-set for a 90°travel.
It features 2 devices to limit the travel:
•
Cams trigger switches to switch off power at an end position or
to signal a position .
•
Mechanical stops mechanically block rotation to protect the valve
in case of over-travel.
They must not be used as travel limits.
Setting a single cam
The cam rotates as the
output shaft and triggers a
switch by pushing on its
lever.
Cams orientation are factory
pre-set, yet you can still re-
adjust them upon the
installation if necessary.
Rep. Function Status before installation
1 Clockwise travel limit Pre-wired, cam pre-set
2 Counter-clockwise travel limit Pre-wired, cam pre-set
3 Clockwise signalling To wire, to set
4 Counter-clockwise signalling To wire, to set
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-head or a
Phillips-head screwdriver.
The cam disk is then turning.
2) Set the cam disk until you
hear a click from the
switch. It indicates the
triggering of the switch.

Make sure the cams contact the switch according to their proper
direction of travel, otherwise you could damage the switch.
