SENSORS
Be sure power to the operator is disconnected.
1. Center each sensor in the bracket with the lenses pointing
toward each other across the door.
2. Attach the sensors to the brackets with the provided hardware.
Finger tighten the receiving sensor wing nut. Securely tighten
the sending sensor wing nut.
3. Run the sensor wires to the operator. Fasten the sensor wire
appropriately.
4 Connect the sensor wires to the operator (refer to Wiring
Connections, page 6).

ALIGN THE PHOTOELECTRIC SENSORS
1. Connect power to the operator. The green indicator lights in
both the sending and receiving sensors will glow steadily
if wiring connections and alignment are correct.
2. If the receiving sensor indicator light is not glowing steadily
(and the invisible light beam path is not obstructed),
alignment is required:
• Loosen the receiving sensor wing nut to allow slight
rotation of the sensor. Adjust sensor vertically and/or
horizontally until the green indicator light glows steadily.
• When the indicator lights are glowing in both sensors,
tighten the receiving sensor wing nut.
