Use wing nuts to fasten safety reversing sensors to brackets, with lenses pointing toward each other across the door. · Run the wires from both safety reversing sensors to the operator. · Strip 7/16" (11 mm) of insulation from each set of wires. Separate white and white/black wires sufficiently to connect to the operator quick-connect terminals: white to white and white/black to grey (Figure 6). The indicator lights in both the sending and receiving eyes will glow steadily if wiring connections and alignment are correct. The sending eye amber indicator light will glow regardless of alignment or obstruction. If the green 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. · Loosen the receiving eye wing nut and adjust the safety reversing sensor until it receives the sender's beam. When the green indicator light glows steadily, tighten the wing nut. Figure 5 Wing Nut 1/4"-20 Carriage Bolt 1/4"-20x1/2" Lens TROUBLESHOOTING THE SAFETY REVERSING SENSORS 1.
