E081
DC Fan Motor Communication Error
There is a communication error between the fan
speed control module and the main board.
Check the wiring and connection
between the fan speed control
module and the main board.
F00
Inverter IPM Overcurrent Shutdown
Inverter IPM input current is too high.
Check the current measurement
and adjust/replace if necessary.
F01
Compressor Start-up Failure
Voltage too low.
Damage to inverter.
Check the voltage measurement.
Check the inverter for damage.
F03
Power Factor Correction (PFC) Error
There is an error with the power factor correction
circuit.
Check the power correction
wiring for a break or short circuit.
F05
DC Bus Overload
The DC bus voltage is higher than the overload
protection limit.
Check the input voltage
measurement.
F06
DC Bus Underload
The DC bus voltage is lower than the underload
protection limit.
Check the input voltage
measurement.
F07
AC Input Underload
The AC input voltage is low causing the input
current to be low.
Check the input voltage
measurement.
F08
AC Input Overload
The AC input voltage is high causing the input
current to be high.
Check the input voltage
measurement.
F09
Input Voltage Read Error
The input voltage reading is incorrect/out of
range.
Check the input voltage
measurement.
F10
DSP and PFC Communication Error
There is a communication error between the
DSP and the PFC.
Check the wiring and connection
between the DSP and the PFC.
F11
DSP Communication Error
There is a communication error between the
DSP and the inverter.
Check the wiring and connection
between the DSP and the
inverter.
F12
Inverter Communication Error
There is a communication error between the
inverter and the main board.
Check the wiring and connection
between the inverter and the
main board.
F13
IPM Over Temperature Protection
There IPM module temperature is too high.
Check the current measurement
and adjust/replace if necessary.
F14
Weak Magnetism Error
The magnetic force of the compressor motor is
too low.
Check the operation of the
refrigeration circuit in terms of
gas pressure and charge.
F15
Input Voltage Lacking Phase
The input voltage has lost a phase.
Check the input voltage
measurement.
F16
IPM Current Read Error
The IPM current reading is incorrect/out of
range.
Check the IPM current
measurement.
F17
Module/Radiator Sensor Error
A transducer has overheated.
Check the current measurement.
