How to troubleshoot no power to Nice MC800?
- A
  Allen YoungAug 13, 2025
  If the Nice Control Unit has no power, start by checking if the unit is properly connected to a power source. Then, inspect the fuse to see if it has blown. If it has, identify the cause of the blown fuse and replace it with a new one that has the same specifications. If the “BlueBus” LED is also unlit or flashing, it could indicate a serious fault, suggesting that the control unit needs replacement.

What to do if Nice MC800 shows electric circuit anomaly?
- C
  Caitlin BarnesAug 21, 2025
  If the Nice Control Unit has an electric circuit anomaly, wait 30 seconds and try giving a command again, disconnecting the power supply if needed. If the problem persists, check which LED is flashing to understand the issue: L1 (motor protection or disconnection), L2 (limit switch anomaly with learning), L3 (limit switch anomaly without learning), or L4 (generic anomaly). After fixing the anomaly, if the condition continues, the electronic board may need replacement.

How to fix BlueBus system error on Nice MC800?

  Matthew SchwartzAug 26, 2025
  If you are encountering a BlueBus system error with your Nice Control Unit, it means the system isn't detecting the same devices that were memorized during the learning phase. Check for disconnected or faulty devices on the BlueBus system and replace them if necessary. If changes were made to the devices, you will need to rerun the device learning procedure.
