Diagnosis and Analysis
EEPROM chip damaged or data wrong or related circuit
damaged
Input over current occured been detected by PIM's hardware
Over current occured during compressor deceleration period
Control board can not communicating with compressor driver
module over 4 minutes
Compressor over current been detected by control board
AC power supply of the driver module get voltage over 280VAC
or driver module get high DC-BUS voltage over 390VDC
The driver module's Compressor current sampling
circuit damaged
Compressor discharge temperature over 115°C,error clear within
3 minutes if temperature goes down and lower than 115°C. Error
status lock if it occurs 3 times in 1 hour.
DC fan motor damage or not connected or related circuit broken.
Error status confirm and lock if occurs 3 times within 30 minutes
Sensor temperature been detected below -55°C or higher
than 90 °C
Sensor temperature been detected below -40°C or higher than
90 °C
or been detected short circuit or open circuit
Sensor temperature been detected below -40°C or higher
than 150 °C or been detected short circuit or open circuit .
Overvoltage been detected in driver module's power factor
correction circuit loop.
Outdoor unit control board can not communicating with intdoor
unit control board over 4 minutes
Discharge & suction temperatureTd-Ts≥80°Cafter compressor
started 10 minutes.Error status lock if it occurs 3 times in 1 hour.
Indoor pipe & indoor ambient temperatureTm-Tai≥-2°C after
compress-or started 10 minutes.Error status lock if it occurs 3
times in 1 hour.
Rotor desynchronizing occured ,caused by overload or load
sharply fluctuating or compressor current sensor cicuit
abnormal or one of the inverter's gate drive signal missing
