What to do if AuCom MVE Controller displays 'Low Control Volts'?
If the AuCom Controller displays 'Low Control Volts', it means the control voltage to the controller has dropped below the required level. Check that the supply voltage at the power interface board is 24 VAC/VDC (± 20 %).
How to fix 'Battery/clock' error on AuCom MVE?
If the AuCom Controller is showing a 'Battery/clock' error, it indicates a verification error on the real time clock or a low backup battery voltage. Reprogram the date and time. Note that the battery is not removable and the main control PCB must be replaced in order to replace the battery.
Why does my AuCom MVE Controller show a current imbalance?
Current imbalance in the AuCom Controller can stem from issues like an imbalance in the incoming mains voltage, motor winding problems, a light motor load, phase loss during Run mode, or a failed SCR.
