•Center each sensor unit in a "C" wrap with lenses pointing toward each other across the door (see Figure 7).

•Secure sensors with the hardware shown. Finger tighten the wing nut on the receiving eye to allow for final adjustment. Securely tighten the sending eye wing nut.

•Run the wires from both sensors to the opener. Use insulated staples to secure the wire to wall and ceiling.

•Strip 1/4" of insulation from each set of wires. Separate white and white/black wires sufficiently to connect to the opener terminal screws:

white to 2 and white/black to 3.

•Plug in the opener. Make sure the Lock Feature is off. Green indicator lights in both the sending and receiving eyes will glow steadily if wiring connections and alignment are correct.

If the indicator light is off in the receiving eye (and the invisible light beam path is not obstructed), alignment is required.

•Loosen the receiving eye wing nut to allow slight rotation of unit. Adjust sensor vertically and/or horizontally until the green indicator light glows with a steady light.

•When indicator lights are glowing steadily in both units, tighten the wing nut in the receiving eye unit.

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).

•Lock switch on Multi-Function Door Control Panel is on. Turn it off.

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.
