What to do if my Lumiax MC4010 Controller shows a short circuit?
If your Lumiax Controller indicates a short circuit, switch off all loads and remove the short circuit. The load will automatically reconnect after 1 minute.
What to do if my Lumiax MC4010 displays an over current?
If the Lumiax Controller is showing an over current, reduce the load. The controller will resume working after 1 minute, and the load will be reconnected when the battery is recharged.
Why is the battery voltage too high on my Lumiax Controller?
If the battery voltage is too high on your Lumiax Controller, check if other sources are overcharging the battery or if the battery parameter is set correctly. If neither of these is the cause, the controller might be damaged.
What to do if my Lumiax MC4010 is over temperature?
If your Lumiax Controller is experiencing over temperature, it will return to normal operation after the temperature decreases.
What to do if the Lumiax MC4010 Controller shows abnormal battery voltage at start-up?
If the Lumiax Controller displays an abnormal battery voltage at start-up, charge or discharge the battery so that the battery voltage is within the normal operating range (8.5~15.5V or 20~30V).
