What to do if my FAAC Gate Opener does not respond to the activating signal?

  William KnappJul 26, 2025
  If your FAAC Gate Opener doesn't respond when you try to activate it, here are a few things you can check: * First, ensure that the main power switch is turned on. * Inspect the control panel terminal strip for any broken or wires that may have become disconnected. * If you're using a radio signal, verify that the code sets on both the transmitter and receiver match. * Try momentarily shorting across terminals 1 and 7 on the control panel. If this works, the problem is likely with the activation device itself.

  If your FAAC Gate Opener is closed and won't open, check the following: 1. Make sure the clutch adjustment isn't too weak. 2. If the motor runs but the gate doesn't move, increase the torque, especially for heavy gates. 3. Check that the closed limit switch is working. The FC status light should be off. 4. Ensure the limit switch plate isn't too far from the limit switch (the distance should be about 3/16 inch). 5. Check fuse F1 and replace it if needed.

  If your FAAC Gate Opener opens but won't close, ensure the closing safety devices are working correctly and aren't activated. An activated reversing device will prevent the gate from closing. Also, check that the FSW-CL light is on, indicating the closing safety isn't active. Finally, make sure the display doesn't show 05, which indicates the Fails Safe Check didn't pass.

  If your FAAC Gate Opener is closed and won't open, try these steps: 1. Ensure the clutch adjustment isn't too weak. 2. If the motor runs but the gate doesn't move, increase the torque, especially for heavy gates. 3. Check the closed limit switch. The FCC status light (or Open LED) should be off, and the limit switch plate should be about 3/16 in. (5 mm) from the switch. 4. Inspect fuse F1 and replace if necessary.

  If your FAAC Gate Opener opens but refuses to close, consider the following: * If no optional reversing devices are connected, ensure a jumper is installed between terminals 4 and 5 on the MPS control panel or 6 and 7 on the B/C control panel. * If you have reversing devices, check if they're working correctly. An activated device will stop the gate from closing. To check, temporarily short across the relevant terminals to bypass the reversing devices. If the gate then closes, the problem lies within the reversing device(s).

Why FAAC Gate Opener opens, but the operator continues to run?
- L
  Larry PriceAug 16, 2025
  If your FAAC Gate Opener opens but then continues to run, check the FC light on the control panel. It should be OFF. If it's ON, inspect the alignment of the limit switch plate. If the FCC light is ON and the limit switch plate is correctly adjusted, replace the limit switch. Note that if the limit switch plates are not detected by the limit switch on the operator, the motor will run for 120 seconds and then the control panel will be in alarm status.

  If your FAAC Gate Opener opens and the operator keeps running, check these: * Look at the FCC light (or Close LED) on the control panel; it should be off. If it's not, check the alignment of the limit switch plate. * If the FCC light remains on and the limit switch plate is correctly adjusted, you may need to replace the limit switch.
