4-4-15 Comp Vlimit error/Comp current limit error
1.Checklist :
1) Is the PFC Shunt(PF2:R062,R063,PF3: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
Terminate the service
Exchange the Outdoor PBA

Connect the comp wire normally
Terminate the service
Correct the sensor position or exchange the
sensor
Restart after returning to the normal load
Is the connection of compressor wire is
normal?
Is the O.C error occurred again?
Is the condition of indoor/outdoor
temperature normal load?
Is the position of temperature sensor and
sensing value normal?
Is the compressor body and interphase
resistance insulated?
Exchange the Outdoor PBA
Restart after power off.
