What to do if my Nice MC424L Control Unit has an internal parameter error?
If your Nice Control Unit shows an error in its internal parameters, wait at least 30 seconds before issuing a command. If needed, disconnect the power supply. If the problem persists, it could indicate a severe malfunction, possibly requiring replacement of the electronic board.
What to do if my Nice MC424L Control Unit has no power?
If your Nice Control Unit isn't receiving power, first verify that power is reaching the unit by measuring approximately 30 V DC (or 24 V DC if battery-powered) at terminals 6-7. Then, inspect the two fuses. If the OK LED is not illuminated or flashing, it indicates a significant failure, potentially requiring replacement of the control unit.
What to do if the obstacle detection function is activated in my Nice MC424L Control Unit?
If the obstacle detection function is activated due to the motors encountering too much resistance during gate movement, verify the cause. If necessary, increase the motor force.
Why is my Nice MC424L Control Unit not working and showing a serious anomaly?
A serious anomaly has been detected. Try turning off the Nice Control Unit for a few seconds. If the problem continues, it indicates a fault, and the circuit board may need to be replaced.
What to do if my Nice Control Unit has fault on the electrical circuits?
If your Nice Control Unit has a fault on the electrical circuits, wait at least 30 seconds and then try again to give a command and if necessary also turn off the power supply; if the status remains there could be a serious failure and the electronic circuit board may need to be replaced.
What to do if my Nice Control Unit exceeded the maximum number of consecutive maneuvers?
If your Nice Control Unit has exceeded the maximum number of consecutive maneuvers or maneuvers per hour, you need to wait a few minutes for the maneuver limiter to reset below the maximum limit.
Why is my Nice MC424L Control Unit stopping due to STOP input intervention?
If your Nice Control Unit is stopping due to the STOP input, it indicates that the devices connected to the STOP input have been activated either at the start of the operation or during movement. You should check the cause of this intervention.
Why is my Nice Control Unit stopping due to photocell intervention?
If your Nice Control Unit is stopping due to photocell intervention, it means one or more photocells are blocking the movement or have reversed it while in progress. Check for any obstructions that may be triggering the photocells.
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 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.
