Cam 3
Cam 4
Cam 3 Adjustment
1. The third cam is Cam 3, 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 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.
Cam 4 Adjustment
1. The fourth cam is Cam 4, 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 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.
