Open Limit:
Raise the door manually to the open position you would like it to stop at. Slightly loosen the wing-nuts that lock
the cam (to the extent that you can rotate the cam by hand while the cam can not rotate itself). Rotate the
open limit cam (inner cam) clockwise by hand in the direction of the limit switch until the cam clicks the open
limit switch (see Fig. 16).
8.2
Closed Limit:
Close the door manually to a closed position so that the bottom edge of the door just touches the floor. Rotate
the closed limit cam (outer cam) by hand anti-clockwise until the cam clicks the closed limit switch (see Fig. 16).
