Outdoor Unit Trouble Shooting - Haier AC35S2SG1FA Mode D'emploi

Troubleshooting
When failure happens,the fan of indoor unit stop running.The method of check failure code as follow.
For outdoor failure,the failure code is outdoor failure LED flash times + 20.
For example,the failure code of outdoor unit is 2. the wired controller of indoor unit will display 16(using hexadecimal method).

OUTDOOR UNIT TROUBLE SHOOTING

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
9Q°C or been detected as short circuit or open circuit..
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°C after compressor
started 10 minutes.Error status lock if it occurs 3 times in 1 hour.
Indoor pipe & indoor ambient temperature
Tm-Tai ≥ 5°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.
