Fault code
Fault type
Possible cause
Remedy action
OH1
Rectifier overheat
1. Air duct jam or fan damage
2. Ambient temperature is too
high.
3. The time of overload running is
too long.
1. Refer to the overcurrent
solution
2. Ensure fan is clean and not
clogged.
3. Low the ambient temperature
4. Check and reconnect
5. Change the power
6. Change the power unit
7. Change the main control panel
OH2
IGBT overheat
EF
External fault
SI external fault trip operated.
Check the external device input
CE
Communication error
1. The baud rate setting is
incorrect.
2. Fault occurs to the
communication wiring.
3. The communication address is
incorrect.
4. RFI noise.
1. Set correct baud rate.
2. Check the communication
connection distribution
3. Set correct communication
address.
4. Check earthing connections
and cable screening.
EEP
EEPROM fault
1. Error of controlling the write
and read of the parameters.
2. Damage to EEPROM
1. Press STOP/RST to reset
2. Change the main control
panel.
PIDE
PID feedback fault
1. PID feedback offline.
2. PID feedback signal lost.
1. Check the PID feedback
signal.
2. Check the PID feedback
source.
END
Time reach of factory
setting
The actual running time of the
inverter is above the internal
setting running time.
Ask for the supplier and adjust
the setting running time.
LL
Electronic underload fault
The inverter will report the
underload pre-alarm according to
the set value.
Check the load and the
underload pre-alarm point.
