5.9 Adjustment of limit switches
1) Remove the cover of the electrical enclosure.
2) Manually raise the door to a nearly open position.
3) Depress the travelling cam retaining bracket and rotate the Open cam (figure 18).
Note: turning the cam towards the center of the shaft increases the door travel. Turning
the cam towards the switch decreases the travel.
4) Manually rotate The Open cam until it depresses the Open limit switch sufficiently so as to
hear the switch click.
5) Release the retaining bracket. Make sure that the bracket engages the slots of both limit
cams after each adjustment.
6) Manually lower the door to a nearly closed position and repeat steps 3 through 5 with the
Close cam.
7) Upon completion of all wiring connections, repeat steps 2 through 6 using the “Stop”
button for adjustments of limit switches to their final, exact positions.
