USER MANUAL 41K4629 LIFT-MASTER

• Entrapment protection devices MUST be installed per the operator owner's manual for each entrapment zone.

• Be sure to DISCONNECT POWER to the operator BEFORE installing the photoelectric sensor.

• The door MUST be in the fully opened or closed position BEFORE installing the LiftMaster Monitored Entrapment Protection device.

• Correctly connect and align the photoelectric sensor.

• For entrapment protection, install the photoelectric sensor BEAM NO HIGHER than 6" (15 cm) above the fl oor.

IMPORTANT INFORMATION ABOUT THE

PHOTOELECTRIC SENSOR Be sure power to the operator is disconnected. When properly connected and aligned, the photoelectric sensor will detect an obstruction in the path of its invisible light beam. If an obstruction breaks the light beam while the door is closing, the operator will stop and typically reverse to the full open position. The sensors must be installed so that the emitter and receiver sensors face each other across the entrapment zone and the beam is no more than 6" (15 cm) above the fl oor for a commercial door for entrapment protection. Either can be installed on the left or right of the entrapment zone as long as the sun never shines directly into the receiver eye lens. The brackets must be securely fastened to a solid surface such as the wall framing. If installing in masonry construction, add a piece of wood at each location to avoid drilling extra holes in masonry if repositioning is necessary. The invisible light beam path must be unobstructed. No part of the door (or door tracks, springs, hinges, rollers or other hardware) may interrupt the beam while the door is closing. If it does, use a piece of wood to build out each sensor mounting location to the minimum depth required for light beam clearance. Additional photoelectric sensors may be added at heights greater than 6" (15 cm) above the fl oor for vehicle/property detection.

ASSEMBLE AND MOUNT THE BRACKETS

The following instructions show recommended assembly of the bracket(s) and “C” wrap based on the wall installation of the photoelectric sensors on each side of the door or on the door tracks themselves. There are also alternate mounting methods which may fi t your installation requirements better. Make sure the wraps and brackets are aligned so the photoelectric sensors will face each other across the door. Mount sensors no more than 6" (15 cm) above the fl oor and at a width between 7'-30' (2.1 m - 9.1 m). 1/4"x1-1/2" Lag Screws 1/4"-20x1/2" Carriage Bolts (with square shoulders) 1/4"-20 Lock Nuts Inside Wall Mounting Bracket with Slot Mounting Bracket with Square Holes “C” Wrap Mounting Bracket with Slot Mounting Bracket with Square Holes “C” Wrap Sensor with Wire Indicator Light Floor Inside Wall Sensor with Wire Inside Wall Indicator Light Mounting Bracket with Square Holes Mounting Bracket with Slot “C” Wrap Floor Attach with Concrete Anchors (Not Provided) Inside Wall “C” Wrap Mounting Bracket with Square Holes 1/4" Lock Nuts Door Track Drill 3/8" Holes 1/4"-20x1/2" Carriage Bolts WALL INSTALLATION

1. Connect each assembly to a slotted bracket, using the hardware

shown. Note alignment of brackets for left and right sides of the door.

2. Finger tighten the lock nuts.

3. Use bracket mounting holes as a template to locate and drill (2)

3/16" diameter pilot holes on both sides of the door, 4-6" (10-15 cm) above the fl oor. Do not exceed 6" (15 cm).

4. Attach bracket assemblies with 1/4"x1-1/2" lag screws.

5. Adjust right and left side bracket assemblies to the same distance

out from mounting surface. Make sure all door hardware obstructions are cleared. Tighten the nuts securely.

6. Center each sensor in the bracket with the lenses pointing toward

each other across the door.

7. Attach the sensors to the brackets with the provided hardware.

Finger tighten the receiving sensor wing nut. Securely tighten the sending sensor wing nut.

DOOR TRACK INSTALLATION

Discard slotted bracket. Drill 3/8" holes in each track and fasten securely with hardware . Do not exceed 6" (15 cm). NOTE: Ensure the door track does not vibrate when the door is in motion. Excessive vibration can create nuisance reversals. Mounting Bracket with Square Holes “C” Wrap #10-32x3/8" Screws #10-32 Lock Nuts Fasten the “C” wraps to the mounting brackets having square holes, using hardware shown.

1. Center each sensor in the bracket with the lenses pointing toward each other across the door.

2. Attach the sensors to the brackets with the provided hardware (as shown). Finger tighten the receiver sensor wing nut. Securely tighten the emitter sensor wing nut.

3. Disconnect power to the operator.

4. Run the sensor wires to the operator. Fasten the sensor wire appropriately.

5. Connect the sensor wires to the operator (refer to WIRING section below).

LOGIC BOARD White White/Black Rubber Washer NOTE: Trolley example is shown.TROUBLESHOOTING If the emitter sensor and receiver sensor indicator lights do not glow steadily after installation, check for:

• Power to the operator

• A short or broken wire

• Incorrect wiring between photoelectric sensors and the operator If the receiver sensor indicator light is off or fl ashing (and the invisible light beam path is not obstructed), check alignment of the sensors and/or for an open wire to the receiver sensor. If the emitter sensor and receiver sensor indicator lights are both glowing steadily but interrupting the photoelectric sensors does not cause the door to reverse when closing, check both sensors to make sure one sensor is the emitter and the other is a receiver sensor as indicated on the sensor housing. NOTES:

• Direct sunlight to the receiver sensor may prevent the operator from closing even when both the emitter and receiver indicator lights are illuminated. Swapping the position of the emitter and receiver sensors will resolve this issue.

• Professional service is required if the operator closes the door when the photoelectric sensors are obstructed. FOR SERVICE OR TO ORDER REPAIR PARTS DIAL: 1-800-528-2806 LiftMaster.com WARRANTY LiftMaster

1. Connect power to the operator.

2. Align the photoelectric sensors so the green LED on the emitter sensor and the green LED on the receiver sensor glow steadily. If both green LEDs blink (and the invisible light beam path is not obstructed), alignment is required:

• Loosen the receiver sensor wing nut to allow slight rotation of the sensor. Adjust sensor vertically and/or horizontally until both green indicator lights glow steadily.

• When the indicator lights are glowing in both sensors, tighten the receiver sensor wing nut.

3. Press the OPEN button to fully open the door.

4. Press the CLOSE button to close the door.

5. Obstruct the light beam while the door is closing. The door should stop and reverse.

The operator will not close if the indicator lights are blinking, alerting you to the fact that the sensor is misaligned or obstructed. Indicator Light 6" (15 cm) max. above fl oor Indicator Light 6" (15 cm) max. above fl oor1
