代碼 P10-10129: I1 DC Bus Imbal

Type: Resettable Fault Coast Either the lower or upper leg of the capacitor bank is getting too much voltage (based on the bus voltage, measured voltage across the lower leg, and a calculation to find the voltage across the upper leg) or the voltage sensing components are damaged. • Check the value of the bus bleeder resistor and bus balancing resistor and replace as necessary. • Inspect the capacitor bank for leakage or damage and replace as necessary. Replacing the capacitor bank assembly also replaces the bus balancing resistor. • Measure the voltage on each half of the bus to confirm the calculations. If the bus measurements aren’t correct, replace the power interface board and/or inverter power supply board.
