Limit switches are needed to stop the door at the correct opened and closed positions. Rotate the screw to free
the limit cam wheel, open the door to desired position, turn the limit cam wheel until OPEN limit switch clicks,
finally tighten the screw.
Rotate the screw to free its limit cam wheel, close the door to desired position, turn the limit cam wheel until
CLOSE limit switch clicks, finally tighten the screw.
After adjusting, you can open the door then close the door and observe whether the door has successfully
reached the opened and closed positions. If the door does not reach the opened or closed position, fine adjust
the limit cam wheel to suit the desired distance. The process is the same as the adjusting as above.
