The L2 error in Voltas AC indicates a Drive Bus Voltage Over Low Protection issue. This error occurs when the system detects that the drive bus voltage has dropped below the required threshold, triggering the over-low protection mechanism. The drive bus voltage is critical for the operation of the compressor and other motor-driven components within the air conditioning system. If the voltage falls too low, it can affect the performance of the unit and potentially damage internal components. When the L2 error is triggered, it typically points to an issue with the power supply, such as low voltage from the main power source, problems with the inverter, or a faulty connection within the drive bus circuit. A sudden drop in voltage can lead to the compressor or other parts of the system not receiving adequate power to function correctly. To resolve the L2 error, begin by inspecting the main power supply and ensuring it provides the correct voltage levels. Check the drive bus circuit and connections for any signs of damage, loose wires, or faults that could cause a drop in voltage. Additionally, the inverter and control board should be checked for any malfunctions affecting the voltage supply. Once the underlying cause is identified and the faulty components are repaired or replaced, the system should reset, and normal operation will resume. Regular maintenance, including monitoring voltage levels and checking electrical components, can help prevent the L2 error from occurring and ensure the reliable performance of your Voltas AC system.
