LiftMaster Monitored Wireless Edge Kit

Introduction

The LiftMaster Wireless Edge Kit provides a Bluetooth® connection between a LiftMaster monitored resistive edge (not included) and the LiftMaster commercial door operator. The maximum range is 130 ft. (39.6 m.) (for best results, install with a clear line of sight between the transmitter and receiver; objects in the path may reduce range). The kit works with LiftMaster monitored resistive edge sensors ONLY. Contact closure edge sensors are NOT supported.

Refer to your LiftMaster operator manual to ensure compatibility (LMWEKITU and LMWETXU are listed under Monitored Entrapment Protection devices of the Accessories section). The transmitter and receiver are UL Recognized Components and meet UL 325 requirements. A monitored entrapment protection device MUST be installed in each entrapment zone.

Compatible LiftMaster® Commercial Door Operators:

• HPH1
• JDC
• JHDC
• TDC

Wire the Receiver

IMPORTANT: Disconnect ALL power to the operator.

1. Open the receiver housing.
2. Route the wire harness from the receiver to the operator's controller. Utilize one of the 1/2 in. conduit holes or knockouts on the enclosure.
3. For HPH1: Connect the wire harness to the EXPANSION BOARD connector labeled "MAIN / W. EDGE" (marked J7 on PCB board).
4. For JDC, JHDC, and TDC: Connect to the "EXP PORT" on the control board.
5. Tighten the Heyco connector with 25 in. lbs. of torque to make the receiver watertight.
6. Reconnect power to the operator. The receiver's blue power LED will illuminate.

Diagram Description: The wiring diagrams show the internal layout of the operator control boards for JDC, JHDC, TDC, and HPH1 models. They highlight the specific connection points (EXP PORT or MAIN/W. EDGE on expansion board) where the receiver wire harness should be connected.

Install Transmitter Batteries and Set Edge Direction

1. Open the transmitter housing.
2. Install the batteries. DO NOT let the bottom housing hang by the wires. Energizer® Ultimate Lithium AA L91 batteries are REQUIRED as replacements.
3. The Open/Close dip switch should be set to CLOSE for door applications.

Diagram Description: This section shows the transmitter housing opened to reveal the battery compartment and the DIP switches. The DIP switches are labeled for OPEN/CLOSE functionality, with the instruction to set them to CLOSE for door applications.

Programming

1. Press the learn button on the RECEIVER board. The red LED will illuminate to indicate programming mode. NOTE: To exit programming mode, press the learn button again.
2. Press the learn button on the TRANSMITTER to be learned. The red LED on the RECEIVER will blink 4 times. NOTE: Learn mode times out after 60 seconds.

Diagram Description: An illustration points to the 'Learn Button' on the receiver board, indicating the primary interface for programming the transmitter.

Wire and Mount the Transmitter(s)

For best results, install with a clear line of sight between transmitter and operator.

1. Route the wires from the edge sensor into the transmitter. Connect the wires to either terminal block (polarity is NOT important). The operator will beep once to indicate the edge sensor has been learned. Apply pressure to the edge. The red LED will flash if the transmitter is wired correctly. Tighten the Heyco connector with 25 in. lbs. of torque to make the transmitter watertight. Use the double hole Heyco connector when connecting 2 edge sensors (for gate operations only).
2. Attach the mounting bracket to the door with the screws provided (8-32 3/8" or 10-16 3/4") at least 3.28 ft. (1 m) above the ground. If installing on a round surface, use zip ties (not provided).
3. Attach the transmitter housing with the screws provided.
4. Place the transmitter onto the mounting bracket and secure with the 1/4" screw provided.

Test

Apply pressure to the edge. The red LED on the TRANSMITTER will flash. The controller LCD should state "WLESS BLOCKED". If the TRANSMITTER LED does not flash, check the transmitter for proper installation and wiring. See the Transmitter and Receiver Troubleshooting page and check the edge sensor for proper installation and wiring.

To Unlearn Device

To unlearn devices, press and hold the learn button on the RECEIVER. Continue to hold the learn button while the red LED flashes. Once the LED stops flashing, device reset is complete, and you can release the learn button.

Mount the Receiver

IMPORTANT: Disconnect ALL power to the operator.

1. Attach the mounting bracket to the operator or wall with the screws provided (8-32 3/8" or 10-16 3/4").
2. Attach the receiver housing with screws provided.
3. Place the receiver onto the mounting bracket and secure with the 1/4" screw provided.
4. Reconnect power to the operator.

Battery Status

When the edge is activated, the red status LEDs on the transmitter(s) and receiver flash to indicate the battery status. NOTE: The receiver LED corresponds to the lowest battery level of all transmitters.

• 1 Flash: Battery is fine.
• 2 Flashes: Battery is low; the operator will beep twice.
• 3 Flashes: Battery is critically low; the operator will not function until the battery is replaced. The operator will either open automatically (fail-safe) or latch at close (fail-secure) based on the operator setting (see the operator's manual for more information).

Diagram Description: An image shows a receiver unit with a flashing red status LED, illustrating the visual indicator for battery status.

Bluetooth® Communication Troubleshooting

• Check for electromagnetic interference from nearby electronics which could be broadcasting at the frequencies used by the transmitter.
• LED and fluorescent lighting systems: Turn off the lights and see if performance improves.
• Wi-Fi®, security systems, radio, cellular, and other wireless equipment: Disable if possible or shorten the distance between the transmitter and receiver.
• Motor magnetic fields, possibly including the operator motor: Make sure the receiver is installed in line of sight to the transmitter or as best as possible.

NOTE: If a Bluetooth® headset used by a technician has interference problems, there is likely interference between the transmitter and receiver.

• Test the battery status in the transmitter; see BATTERY STATUS page. Replace batteries if necessary.
• Distance between transmitter and receiver may be too far. Shorten the distance between the transmitter and receiver.
• Check for loose wiring connections between the edge sensor and transmitter which can cause intermittent drop outs.
• Open the edge sensor, transmitter, and receiver to make sure no moisture is present.
• Test the transmitter and receiver; see TEST page. A bad transmitter or receiver is the least likely cause; test all other alternatives first.

Troubleshooting

The diagnostic display on the gate operator control board shows a code to indicate a problem. See operator manual for diagnostic codes.

• F63 BLE MISS. Open Edge: See Bluetooth Communication Troubleshooting section. Cycling the door or testing the edge may clear this fault code.
• F64 BLE MISS. Close Edge: See the Bluetooth Communication Troubleshooting section. Cycling the door or testing the edge may clear this fault code.
• F68 CRITBATT: Check batteries.
