PHOTO BEAM TEST

1 Check that the opener has power. The green LEDs on

the sender and receiver should be lit.

2 If the receiver’s green LED is on, but the red LED is off,

the receiver has power but is not detecting the infrared

beam from the sender. The red LED might  ash when

the beam is partially detected. This can be caused by

mis-alignment or something blocking the beam. Adjust

the photo beam sender and receiver while watching

the receiver’s red LED (stay out of the beam while aligning it). When the red LED stays on, rotate the

sender towards the ceiling and stop when the red LED on the receiver begins to  icker. Rotate the sender

back towards a horizontal position with the  oor and stop as soon as the red LED on the receiver lights

solid. The beam is now properly aligned.

NOTE: If the receiver’s red LED remains off, check for: 1) Dirt on the

receiver’s lens, 2) Sunlight shining into the receiver’s lens, 3) A short

in the photo beam wiring (from staples or at the opener terminals).

3 With the door closed and the opener disengaged (Fig. A) from the

door, press the wall station’s button to move the traveler (the part

on the belt or chain that the trolley engages with) to the up position

(away from the door).

NOTE: Do not cycle the opener to full travel without the door

connected.

4 Push the wall station’s button again. While the traveler is moving to

the down position (toward the door), block the photo beam. THE

TRAVELER MUST STOP, THEN REVERSE TO THE UP POSITION.

The opener’s light should  ash three times.

5 Place an object in the path of the photo beam. Check that constant

pressure is required on the wall station’s button to cause the traveler

to move toward the down position. Release the button before the

opener stops; check that the traveler returns to the up position.

NOTE: The garage door opener will not respond to a CLOSE

command from a radio transmitter if the photo beam is blocked.

6 To reconnect the opener,  ip the release lever up. Raise the door manually until the opener reconnects.
