•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 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.

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 off, dim or flickering in the receiving eye (and the invisible light beamm path is not obstructed), alignment is required.

•Loosen the sending eye wing nut and re-adjust, 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 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 flash 10 times. (If bulbs are not installed, 10 clicks are audible.) See page 17.
