MOUNTING AND WIRING THE SAFETY SENSORS

•Slide a 1/4"-20x1/2" carriage bolt head into the slot on each sensor. Use wing nuts to fasten sensors to brackets, with lenses pointing toward each other across the door. Be sure the lens is not obstructed by a bracket extension. See Figure 5.

•Finger tighten the wing nuts.

Recommended Wire Routing

1. Using insulated staples, run the wires from both

sensors to the rail at the door header

(see Figure 6).

2. Cross and twist the two wires where they meet

the rail (see Figure 6, Illustration A). Run the wires

inside the channels at the top of the rail, along

each side, to the motor unit. Do not use the lower

(trolley) channels. Use a screwdriver tip to tuck

the wires snugly into the channels.

NOTE: If your access door is near the garage

door, you may choose to install the door control at

this time and run the door control wire along the

rail with the sensor wires. Use one rail channel for

the door control wire and the other channel for

both sensor wires. If you choose this option, follow

instructions 1-3 on page 20 now.

3. Pull wires taut across the top of the chassis and
