Adjusting The Actuator Auxiliary Switches - Promation Engineering P2 DC Series Installation & Operation Manual

Adjusting the actuator Auxiliary Switches

Cam 3
Cam 4
Adjust Cam 3
1. The THIRD cam is Cam 3, the CW auxiliary switch adjustment. Drive
the actuator to its CW position. Then 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 and cam to the LEFT until you hear the "click" on
the third switch. Continue to rotate the cam between 3 and 5 degrees
to the LEFT to make sure the auxiliary cam switch changes state
before the actuator reaches its end of travel electrically. Tighten the
cam set screw.
Adjust Cam 4
1. The FOURTH cam is Cam 4, the CCW auxiliary switch adjustment.
Drive the actuator to its CCW position. Then 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 fourth 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.
