Wayne-Dalton 3651-372, 3012, 3014, 3750-372 Photoelectric Safety Sensor Alignment

Step 3: Photoelectric Safety Sensor Alignment

IMPORTANT! - This infrared safety sensor sends an invisible beam of light from the sending unit to the receiving unit across IN the door opening. The door opener will not operate until the safety sensor is connected to the power unit and properly aligned. If the invisible beam of light is misaligned or obstructed, an open door cannot be closed by the transmitter or a momentary activation of the wall mounted push button. However, the door OUT may be closed by holding your finger on the wall push button (constant pressure) until the door travels to a fully closed position.

WARNINGFAILURE TO MAKE ADJUSTMENTS COULD RESULT IN SEVERE OR FATAL INJURY.

At this point you will be able to activate the opener; it will open, but will not close the door unless the sensors are aligned and unobstructed. The safety sensors can be aligned by moving the sending and receiving units in or out (see Fig. 5) until the alignment light on the receiving unit comes on. The 1/4-20 carriage bolt can be loosened to move the unit in or out, as required. If you have difficulty aligning beams, check that both brackets are mounted at the same height and remount if necessary. Additional minor adjustments can be made by lightly bending the mounting brackets (see Fig. 6).Once the alignment light comes on, tighten all bolts and mounting screws. Finish securing all wiring. Make sure not to break or pierce any of the wires. Loop and secure any extra wire. Now, using the wall station’s up/down button, activate the opener and check that it will operate through full open and close cycles.

Step 4: Photoelectric Obstruction Sensing Test

Starting with the door in the fully open position, place a 6” high object on the floor progressively one foot from the left side of the door, center of door and one foot from the right side of the door. (Fig. 7) In each position, activation of the opener with the wallstation up/down button should cause the door to move no more than one foot, stop and then reverse to fully open position. The same 6” high object when placed on the floor, while door is closing, should also cause the door to reverse.

WARNING WHEN PERFORMING THIS PART OF THE TEST, DO NOT PLACE YOURSELF UNDER DESCENDING DOOR, OR SEVERE OR FATAL INJURY MAY RESULT.

WARNING IF THE OPENER DOES NOT RESPOND PROPERLY, OR FAILS THESE TEST,

HAVE A QUALIFIED SERVICE PERSON MAKE NECESSARY ADJUSTMENTS/REPAIRS. FAILURE TO MAKE ADJUSTMENTS COULD RESULT IN SEVERE OR FATAL INJURY.
