•Plug in the opener. The indicator lights in both the sending and receiving eyes will glow steadily if wiring connections and alignment are correct.
The sending eye amber indicator light will glow regardless of alignment or obstruction. If the green indicator light in the receiving eye is off, dim, or flickering (and the invisible light beam path is not obstructed), alignment is required.
•Loosen the sending eye wing nut and readjust, aiming directly at the receiving eye. Lock in place.
•Loosen the receiving eye wing nut and adjust sensor until it receives the sender’s beam. When the green indicator light glows steadily, tighten the wing nut.
REVERSING SENSORS
1.If the sending eye indicator light does not glow steadily after installation, check for:
•Electric power to the opener.
•A short in the white or white/black wires. These can occur at staples, or at opener connections.
•Incorrect wiring between sensors and opener.
•A broken wire.
2.If the sending eye indicator light glows steadily but the receiving eye indicator light doesn’t:
•Check alignment.
•Check for an open wire to the receiving eye.
3.If the receiving eye indicator light is dim, realign either sensor.
NOTE: When the invisible beam path is obstructed or misaligned while the door is closing, the door will reverse. If the door is already open, it will not close. The opener lights will blink 10 times. See page 20.
