• Sliding Gate Opener Troubleshooting: 
     
    Scenario 1:  
    No Power Is Going into the Opener: 
     
    If the unit runs off of 120V AC have the customer confirm the following: 

  • Approximately 120V AC is going into ports L (load/white) and N (neutral/black) terminals (use multimeter). 

  • Check fuse. 

  • Remove all accessories and jumper photocell ports (16 and 17) with a spare 18GA wire. If the gate operates normally, add accessories one at a time until the problem is located. 

  • Replace the circuit board if all areas are fine. 
     

  • If the unit runs off of 230V AC have the customer confirm the following: 

  • Approximately 230V AC going into the L and N terminals (use multimeter). 

  • Check fuse. 

  • Remove all accessories and jumper photocell ports (16 and 17) with a spare 18GA wire. If gate operates normally, add accessories one at a time until a fault is found.  

  • Replace the circuit board if all areas are fine. 
     
     
    Scenario 2:  
    The Gate Opener is Only Opening OR Closing: 
     

  • Have the customer remove the limit switch wires from the following ports (OP, CO, CL) on the circuit board.  

  • Jumper those same ports with (2) spare 18GA wires. The first wire connects ports OP and CO while the second wire connects ports CO and CL. This will allow the unit to work successfully in both directions if the limit switch is the issue. 

  • However, the jumper test will cause the unit to not respect the magnet stop points, so ensure that you manually stop the unit before those points. 

  • If the test works as intended, replace the limit switch. 

  • If the unit is still operational, the circuit board needs to be replaced. 

  • Please note that you can find the limit switch tests in Freshdesk canned responses. 
     
     
    Scenario 3:  
    The Gate Opener is Going Past the Limit Switch: 
     

  • Replace the limit switch as the sensor is faulty. 
     
     
    Scenario 4:  
    Manual Release Key Malfunction: 
     

  • Replace transmission as this is a physical defect. 
     
     
    Scenario 5:  
    Gate Operator Starts and Stops During Cycle Travel: 
     

  • Replace the transmission as this indicates that the internal gear is stripping. 
     
     
    Scenario 6:  
    The Gate Opener is Emitting a Grinding Noise: 
     

  • Replace the transmission as this indicates that the internal gear is stripping. 
     
     
    Scenario 7:  
    Wireless Devices Suddenly Disconnect from the Unit: 
     

  • Press and hold the learn button for a minimum of 10 seconds to unlearn all wireless devices. 

  • Initiate the learn process for the wireless device. 

  • If the device relearns, the transmitter was receiving interference. 

  • If the device does not relearn, replace the circuit board as the receiver is defective. 
     
    Scenario 8A: 
    To Learn Remotes (LM123) 
     

  • Press the AN button on the circuit board. 

  • LED2 light will turn on and off 

  • The beeper will beep for roughly 1 second 

  • Press your chosen button on your remote 

  • The beeper will ring for roughly 2 seconds 

  • LED2 light will turn on for about 2 seconds 

  • Up to 100 remotes can be learned and used 

  • Please note that the LM123 can only be used with the AC/AR1400/2000 series gate openers/circuit boards. 
     

    Scenario 8B: 
    To Learn Remotes (LM122/124) 
     
     

  • Press and release the learn button on the circuit board. 

  • The LED Light on the circuit board will turn on. 

  • Press either the A button or the B button on the remote 2 times in 2 seconds. 

  • The LED light will flash for 4 seconds. 

  • The remote has been learnt. 

  • Please note that to erase all the remote codes, press and hold the learn button on the circuit board until the LED light turns off.  

  • Up to 6 LM124 remotes can be paired to the circuit board/gate opener at a time. 
     
     
    Scenario 9A: 
    Using the LM123 
     

  • The LM123 operates in a single channel mode. 

  • All 4 buttons have the same function. 

  • With each press of the programmed/learned remote button, the gate will open, stop, close, or go through the stop cycle. 

  • Buttons 1, 2, and 3 are used to open or close the gate. 

  • Button 4 can be used to set pedestrian mode. 

  • Please note that if you cancelled pedestrian mode, button 4 can be used the same as the other 3 buttons. 
     
     
    Scenario 9B: 
    Using the LM124 
     

  • The A button allows the gate opener to work in regular function (open-stop-close-stop-open) 

  • When the Midway Mode function is enabled, the B button is used to open the gate for the pre-set amount of time. 

  • When the Midway Mode function is disabled, the B button allows the gate opener to work in regular function (open-stop-close-stop-open). 
     
     
    Scenario 10: 
    Setting Up the Control Board 
     

  • 1. DIP Switches 
    The DIP Switches set the running time of the motor in Midway Mode, the auto close time, and fast change of the open/close direction. 

  • DIP Switches #1-#2: Running time of the motor in Midway Mode –  
    This mode enables the user to drive the vehicle through the gate when the gate opens to a specific point. 

  • If Dip Switch #1 is on, the running time of the opener in Midway Mode is 2 seconds. 

  • If Dip Switch #2 is on, the running time of the opener in Midway Mode is 4 seconds. 

  • If Dip Switches #1 and #2 are both on, you add the running time for both together, so the running time in Midway Mode would be 6 seconds. 

  • Please note that the Midway Mode function is disabled if both DIP Switches are off. The factory default setting is disabled, so the first two DIP Switches are off. 

  • DIP Switches #3-#4: Auto close time of the gate opener. 

  • If DIP Switch #3 is on, the auto close time will be set for 30 seconds. 

  • If DIP Switch #4 is on, the auto close time will be set for 60 seconds. 

  • If DIP Switches #3 and #4 are both on, you add the auto close time for both together, so the auto close time would be 90 seconds. 

  • Please note that if DIP Switches #3 and #4 are off, the auto close function will be disabled. This is the factory default setting. 

  • DIP Switch #5: Left/Right Open. 

  • If DIP Switch #5 is on, it will be a right opening gate. 

  • If DIP Switch #5 is off, it will be a left opening gate. 

  • You can turn the switch to off to change the opening direction. 

  • The DIP Switches are now set. Please continue to step #2 for potentiometers. 
     

  • 2. Potentiometers – Adjusting the Open and Close Stall Force. 

  • Potentiometer A is used to adjust the open stall force. 

  • Potentiometer B is used to adjust the close stall force. 

  • To increase the stall force, turn the potentiometer clockwise. 

  • To decrease the stall force, turn the potentiometer counterclockwise. 

  • The potentiometers are now set. 
     

  • The circuit board is now set up. 
     
     
    Scenario 11: Testing the Reverse Sensitivity 
     

  • The reverse sensitivity adjustment is in opposite correlation with the stall force adjustment. As such, the stall force level is higher and the reverse sensitivity level is lower. 

  • Place an immobile object along the gate’s path. 

  • Operate the gate and allow it to strike the object during the open and close cycles. 

  • The gate must reverse as soon as the object has been struck. 

  • If the gate doesn’t reverse, please increase the reversing sensitivity by turning the potentiometer counterclockwise – turn the potentiometer towards the min position. 

  • Please note that if the sensitivity setting is too high, the gate will stop or reverse too easily by itself, especially if there is some type of obstruction or resistance such as a strong wind or heavy snow. Always check the reverse sensitivity every time you reset the circuit board or restart it after shutting the power off. 
     
     
    Quick Troubleshooting: 
     

  • Scenario 1: Motor Only Runs in One Direction (Open or Close) 

  • A: The limit switches have failed. Disconnect the limit switches to see if the motor begins running in both directions. 

  • B: The motor’s start capacitor has failed. Replace the capacitor. 

  • C: There may be a problem with the electrical component on the circuit board. Replace the circuit board. 
     

  • Scenario 2: The Gate Will Neither Open or Close 

  • A: Check to make sure the power switch is on. 

  • B: The limit switches have failed. Disconnect the limit switches to see if the gate will begin operating normally. 

  • C: The connecting wires or terminal blocks on the circuit board are loose. Check that everything is connected properly. 

  • D: The gate opener may be overheating. Please let it cool for at least 20 minutes before trying to use it again. 

  • E: There may be a problem with the electrical component on the circuit board. Replace the circuit board. 

  • F: There may be a problem with the motor. Replace the motor if all else fails. 
     

  • Scenario 3: The Remote Control Does Not Work 

  • A: You might be too far away from the gate opener. Try moving closer. 

  • B: The codes may have become corrupt. Erase the remote and relearn the remotes to the circuit board. 

  • C: If there is no indicator light on the remote, replace the battery. 

  • D: If all else fails, replace the circuit board as the receiver on the board may have become corrupt. 
     

  • Scenario 4: Gate Stops in Mid-Travel or Mid-Reverse (usually when the user is using the remote): 

  • A: Check to make sure the gate is not obstructed. 

  • B: The opening or closing stall force may be too low. Turn Potentiometer A or B clockwise to increase the force. 
     

  • Scenario 5: The Gate Won’t Close 

  • A: Check if there is any sort of obstruction around the photocell area (if you have photocells). 

  • B: The start capacitor of the motor is no longer working. Replace the capacitor. 

  • C: The electrical component on the circuit board is compromised. Replace the circuit board. 

  • D: There are 2 magnet brackets – one is higher and the other is lower. Try to switch the bracket positions. 

  • E: Try to switch the CL (close) and OP (open) limit switch wires. 

  • F: There are two switches inside the actual limit switch. One is positioned higher and the other is positioned lower. Adjust the positions of the switches. 
     

  • Scenario 6: The Motor Runs but the Gate Won’t Move 

  • A: The clutch for the emergency release is not adjusted properly and is slipping. Readjust the clutch. 

  • B: The start capacitor of the motor is no longer working. Replace the capacitor. 

  • C: The circuit board may be compromised. If all else fails, replace the circuit board.
