Advanced Diagnostic Codes for LMWEKITU

More than one problem may exist. A combination of issues may be affecting the performance of the LMWEKITU. Work each issue individually until all LMWEKITU advanced diagnostics stop logging.

Transmitter and Receiver Troubleshooting

• Test programming from transmitters to a receiver, see 6 TEST page 2. Ensure you receive a signal (status LED) when you depress the edge(s). Reprogram transmitters as necessary.
• Test the battery status in all transmitters, see BATTERY STATUS page 3. Replace batteries if necessary. Energizer® Ultimate Lithium AA L91 batteries are REQUIRED as replacements. If incorrect batteries are installed, the transmitter will fail within a few months.
• Check the OPEN/CLOSE DIP switch configuration on transmitters for the correct open or close direction, see 2 INSTALL TRANSMITTER BATTERIES AND SET EDGE DIRECTION page 2. If you change the dip switch configuration unlearn and relearn all safety devices. Refer to your gate operator manual for relearning safety devices.
• If using the I2C interface board, bypass the board to test the receiver:
  1. Unplug the I2C board from the control board.
  2. Connect the receiver to the EXP. BOARD terminal on the control board.
  3. Test for proper operation from the edge sensor(s), see 6 TEST page 2. If edge sensor(s) operate normally then replace I2C board or check for proper installation of I2C board to the expansion board, see 1 WIRE THE RECEIVER page 1.

Edge Sensor Troubleshooting

• Open the edge sensor caps and ensure the contact plug is installed correctly and the pins are not corroded. Make sure that the lower edge cap is installed correctly, the weep holes are open and free of obstruction, and the sense resistor pins are not corroded. 
• Test edge sensor wiring:
  • Remove the wires from the transmitter terminal blocks.
  • Measure the resistance between the two wires to the edge. The resistance should read 8.0kΩ to 8.4kΩ without the edge depressed.
  • If it reads open (infinite ohms), the resistor is missing or incorrectly installed. Make sure the contact plug installed as shown above. Cut 1/4″ – 1/2″ off the edge and reinstall the contact plug as shown. If it still reads open, replace the edge.
  • If it reads below 100Ω, replace the edge.
  • Depress (squeeze) the edge. If it reads more than 100Ω, replace the edge.
  • Replace the parts on the edge when complete.

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 the recommended location, see RECEIVER MOUNTING LOCATION page 5.
    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 3. Replace batteries if necessary.

• The 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 dropouts. See, Edge Sensor Troubleshooting.

• Open the edge sensor, transmitter, and receiver to make sure no moisture is present.

• Test the transmitter and receiver, see 6 TEST page 2. A bad transmitter or receiver is the least likely cause, test all other alternatives first.

I2C Communication Troubleshooting

• Check that the POWER LED on the expansion board. If it is not flashing once a second, an I2C communication problem is likely. NOTE: If the I2C interface board is installed, the POWER LED will be underneath.
• Check the DATA LED on the control board. If it is not flashing, press and release the STOP button on the control board to wake the system.
• Check the wire harness to ensure that the plugs are correctly inserted over the jacks pin for pin.
• Check for a loose pin on one of the wire harnesses:
  • Replace the existing wire harness and check for proper operation.
  • Plug the receiver directly into the control board and check for proper operation.
• Check that the I2C interface board is installed correctly. Make sure the I2C board plug is correctly installed on the expansion board jack. See 1 WIRE THE RECEIVER page 1.
• Check the accessories:
  • Remove all accessories from the expansion board, connect them to the control board, and check for proper operation.
  • If the plug in loop detector model LOOPDETLM is installed, substitute with an external loop detector and check for proper operation.
• A bad control board, expansion board, or I2C interface board can cause failure, but is unlikely. Check other possibilities before replacing boards.
