Outdoor display I_trip error/ PFC over current
1.Checklist :
1) Is the PFC Shunt(R062,R063) resistance value correct? Check the resistor is opened
2) Is the condition of surrounding temperature abnormal overload?
3) Is there any problem as like the temperature sensor separation or measurement value error?
4) Is the interphase resistance of compressor normal?
