Testing with Obstruction
With the sensors properly aligned, place
an obstacle in the path of the beam. The
transmitting sensor's red LED should be on,
the receiving sensor's blue LED should be off.
Remove the obstacle, both LEDs should be on
steadily.
NOTE:
• Be sure to stay out of the beam's path while aligning.
• The LED in the safety beam sensors will flash in every 10 seconds during standby mode.
NOTE:
If the transmitting sensor LED does not glow steadily, check the following:
I. Power to the opener is connected.
II. A short in the white or white/red wires (from wire holders or at the openers terminals).
III. Incorrect wiring between sensors and opener.
IV. A broken wire.
If the transmitting sensor LED glows steadily but the receiving sensor LED doesn't glow:
I. Check alignment.
II. Check for an open wire to the receiving sensor.
III. Check for dirt on lens, or sun shining into lens.
