This actuator has been factory calibrated and tested to stop at 0 degrees for CW position and to stop at 90 degrees
for CCW position. The Auxiliary Switch settings are based on those stops. Ideally the Auxiliary Switches are set a few
degrees in advance of the respective stop switches, so if you had adjusted either the CW or CCW you may need to
adjust these as well.
Adjust CW Auxiliary Cam
1. Cam 3 is the third cam up from the bottom (red) and is the CW auxiliary
switch adjustment, an optional switch typically used to indicate the actuator
reached its CW position.
2. Drive the actuator to its CW position. Use a sharp 2.5mm hex key to free up
the cam set screw.
Take care not to let the hex key slip at this stage, it
can easily strip out.
Once it is free adjust it as described below:
•
Rotate the hex key to the LEFT 10-15 degrees until you hear a
click. This will reset the switch roller arm.
•
Gently tighten (CW) the set screw only until slight pressure is
felt. Ideally the set screw rides along the camshaft.
•
Now SLOWLY rotate the hex key to the RIGHT, pushing the
cam, until you hear the “click” on the bottom switch.
•
Continue to rotate the cam between 3 and 5 degrees to the
RIGHT to make sure the auxiliary cam switch changes state
before the actuator reaches its end of travel electrically.
•
Tighten the cam set screw.
Adjust CCW Auxiliary Cam
1. Cam 4 is the fourth cam up from the bottom (green) and is the CCW
auxiliary switch adjustment, an optional switch typically used to indicate
the actuator reached its CCW position.
2. Drive the actuator to its CCW position. Use a sharp 2.5mm hex key to free
up the cam set screw.
Take care not to let the hex key slip at this stage,
it can easily strip out.
Once it is free adjust it as described below:
•
Rotate the hex key to the RIGHT 10-15 degrees until you hear
a click. This will reset the switch roller arm.
