To reduce the risk of electric shock, your garage door
opener has a grounding type plug with a third grounding
pin. This plug will only fit into a grounding type outlet.
If the plug doesn't fit into the outlet you have, contact a
qualified electrician to install the proper outlet.

To avoid installation difficulties,
do not run the opener until Step 9 below.

Sensor
Installation
Aligning the Safety Sensors
• Plug in the opener. Green indicator lights in both the
sending and receiving eyes will glow steadily if wiring
connections and alignment are correct.
The sending eye indicator light will glow regardless of
alignment or obstruction. If the indicator light is of£ dim,
or flickering in the lvceiving c3,e (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
vertically and/or horizontally
until it receives the
sender's beam. When the green indicator light glows
steadily, tighten the wing nut.

Trouble Shooting
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 under staples or at screw terminal connections.
• Incorrect wiring between sensors and opener.
• An open wire (wire break).
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 itwisible beam path is' obstructed or
re#aligned
while the door is' closing, the door will
