•Center each sensor unit in a “C” wrap with lenses pointing toward each other across the door (see Figure 6).
•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 (see Figure 7). Use insulated staples to secure the wire to wall and ceiling.

•Strip 1/4" (6 mm) 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. The 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 in the receiving eye is off, dim, or flickering (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 until it receives the sender’s beam. When the green indicator light glows steadily, tighten the wing nut.
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 at staples, or at opener connections.
•Incorrect wiring between sensors and opener.
•A broken wire.
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 blink 10 times. (If bulbs are not installed, 10 clicks can be heard.) See page 15.
