I_trip error, PFC over current
1.Checklist :
1) Is the PFC Shunt(A*V18***:R062,R063,A*V24***:R807,R808,R809) 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?
2. Troubleshooting procedure
Is the condiƟon of indoor/outdoor
temperature normal load?
Restart aŌer returning to the normal load
YES
YES
Is the connecƟon cable for the
compressor and power terminal
normal?
YES
Correct the cable connecƟon
Is the I_trip error
occurred again?
NO
NO
Exchange the Outdoor PBA
Is the posiƟon of temperature
sensor and the sensing value
normal?
Correct the sensor posiƟon or exchange the sensor
NO
YES
Restart aŌer power oī.
Terminate the
service
NO
