What to do if my Nice MC424L has a fault?
If your Nice Control Unit indicates a fault, begin by checking the power supply and ensuring the fuses are intact. If the fuses have tripped, identify and rectify the cause of the fault before replacing them with new fuses of the same rating.
What to do if my Nice MC424L gives an error in internal parameters?
If your Nice Control Unit reports an error in its internal parameters, wait for at least 30 seconds before attempting to send another command. If the issue persists, try turning off the main power supply and then turning it back on. If the error continues, it may indicate a serious malfunction, possibly requiring replacement of the electronic circuit board.
What to do if my Nice MC424L has a serious fault?
If the Nice Control Unit indicates a serious fault, try turning it off for a few seconds and then turning it back on. If the fault persists, the electronic circuit board likely needs to be replaced.
What does it mean if my Nice Control Unit indicates that a command preventing other commands is already present?
Check the type of the “always present” command. For example, it could be a command from a clock on the AUX input.
