Fault code Fault type Possible cause What to do
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. Redistribute
dredge the wind channel or
change the fan
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
S1…S5 external fault input
terminals action
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 wrong.
4. There is strong interference to
the communication.
1. Set proper baud rate
2. Check the communication
connection distribution
3. Set proper communication
address.
4. Change or replace the
connection distribution or
improve the anti-interference
capability.
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 source
disappear
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.
