PHOTOCELL INSTALLATION PROCEDURE
NOTE:
Overhead Door Corporation Photocell System is a safety device which operates by transmitting an invisible beam
near the floor of the garage door opening. When the beam is uninterrupted, the automatic garage door opener
will function normally. However, an obstruction in the path of the beam will cause the door to open fully when
closing, or prevent an open door from closing.
The Photocell system must be operating properly and be
unobstructed for the door to close.
1.
The Photocell mounting brackets included were designed to replace the bottom door track brackets. Mount the photocell
.,
brackets to the wall and the door track centered 5 inches above the floor such that the photocell transmitter and receiver will
face each other. The invisible beam must not be obstructed by moving door parts and must be broken by a 6" tall obstruction.
Some installations may require this bracket to be mounted to the floor.
..
2.
Route a pair of wires from the photocell receiver (the one with the LED) up to the powerhead. Connect one wire to the "photo"
terminal on the receiver and the "photo" terminal on the powerhead. Connect the other wire to the "common" terminals.
See wiring diagram below. NOTE: Polarity must be maintained. Overhead Door two conductor wire is P/N 108763-0001.
3.
Secure the photocell receiver to bracket using the #8 screws provided.
4.
Connect the photocell transmitter to the powerhead following the same procedure as in step 2 above.
5.
Mount the photocell transmitter to the bracket using the #8 screws provided.
6.
Apply power to the photocell system by reconnecting the operator to AC power. The LED on the photocell receiver should
be illuminated.
If not illuminated, realign the units until the LED is constant.
The photocell is adjustable in all planes.
Adjustment is made by tightening the #8 screws holding the photocell to the bracket. The photocell will move in the direction
of the screw being tightened.
