Setting Limit Switches
1. Turn OFF electrical power.
2. Locate limit switches at end of motor.
3. Refer to Fig. 2. The OPEN position and CLOSE position of the door curtain have to be
set. This is where the curtain will automatically stop.
4. Remove the protective cap from the motor head. Depress fully both limit switch push
buttons (if not already pushed). They will automatically lock in the down position.
5. Turn ON the electrical power switch and check that the drive pipe rotates correctly. If not,
put the electrical switch in the OFF position, disconnect all power sources, and reverse
the black and red motor connection wires at the terminal block.
6. OPEN Limit. Bring motor rotation into desired open position. Turn OFF power switch
when position is reached. Unlock the OPEN limit switch push button by depressing and
releasing it. This sets the OPEN limit.
CLOSE Limit. Repeat the above procedure to set the CLOSE limit.
7. Allow the motor to run in both directions, until it shuts off in the stop positions.
Note: Because of the built in thermal protection feature, the motor may shut off
automatically after running without interruption for an extended period of time. Please
wait until the motor has cooled off and is ready for operation again, (approximately 10-15
minutes).
8. Changing the Set Stop Position
Press the limit switch adjustment button that lies in the direction of rotation. Bring the
curtain into the desired stop position. Release the limit switch adjustment button by
pressing it down again.
