Adjusting Ccw And Cw Positions (Cam Adjustment) - Promation Engineering P1.A Series Installation & Operation Manual

Adjusting CCW and CW positions (Cam adjustment)

Remove power from this device BEFORE making any End of Travel cam adjustments.

If the End of Travel cams are adjusted at all, the actuator must be recalibrated. Travel
cams must be set with a rotation of 90° or less for a successful AutoCalibration.
Cam 1 Adjustment
1. The lower cam is Cam 1, the CCW end-of-travel adjustment. Once the actuator
is at its required CCW position, with POWER OFF, use a 2.5mm hex key to
free up the cam set screw. Once it is free, rotate the hex key to the RIGHT 10-
15 degrees to reset the switch roller arm. Then snug the set screw up against
the camshaft (CW) until slight pressure is felt. Then SLOWLY rotate the hex
key pushing the cam to the LEFT until you hear the "click" on the bottom switch
indicating that correct adjustment has been achieved. Tighten the cam.

Cam 2 Adjustment
1. The second cam is Cam 2, the CW end of travel adjustment. Once the actuator
is at its required CW position with POWER OFF, use a 2.5mm hex key to free
up the cam set screw. Once it is free, rotate the hex key to the LEFT 10-15
degrees to reset the switch roller arm. Then snug the set screw up against the
camshaft (CW) until slight pressure is felt. Then SLOWLY rotate the hex key
to the RIGHT until you hear the "click" on the second switch indicating that
correct adjustment has been achieved. Tighten the cam set screw.
2. Apply power to the actuator and drive CCW at least 15-20 degrees. Then drive
the actuator CW until the cam stops the electrical travel. Check to be sure this
is the correct CW position you require. Repeat step 1 if further adjustment is
needed. Remove power from the actuator.
3. If using the Auxiliary Switches, adjust Cam 4 per instructions on page 8.
