Check End Of Travel Settings; Adjusting The Actuator Ccw And Cw Positions - Promation Engineering PX1 Series Installation & Operation Manual

Check End of Travel Settings

The actuators are tested, calibrated and shipped in the Full CW position and End of Travel cams are set at 90 degrees
from each other.
A. Set the control device (valve or damper) to the closed position.
B. Mount the actuator to the device to be controlled (valve or damper).
C. Insure that the CW End of Travel cam trips the CW End of Travel switch at the correct CW point.
C.1. If the switch does not change state at the correct CW position, adjust CAM 2 per instructions below.
D. Manually move (see Manual Override on page 6) the actuator so the valve or damper is in the fully CCW position.
E. Insure that the CCW End of Travel cam trips the CCW End of Travel switch at the correct CCW point.
E.1. If the switch does not change state at the correct CCW position, adjust CAM 1 per instructions below.

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
pushing the cam to the RIGHT until you hear the "click" on the bottom switch
indicating that correct adjustment has been achieved. Tighten the cam.

2. Apply power to the actuator and drive CW at least 15-20 degrees. Then drive
the actuator CCW until the cam stops the electrical travel. Check to be sure this
is the correct CCW position you require. Repeat step 1 if further adjustment
is needed.
3. If using the Auxiliary Switches, adjust Cam 3 per instructions on page 6.
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 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 to
the LEFT 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 6.
