END
LL Electronic underload fault
Fault type
1. Air duct jam or fan damage
2. Ambient temperature is too
high.
3. The time of overload running is
too long.
SI external fault trip operated.
1. The baud rate setting is
incorrect.
2.
communication wiring.
3. The communication address is
incorrect.
4. RFI noise.
1. Error of controlling the write
and read of the parameters.
2. Damage to EEPROM
1. PID feedback offline.
2. PID feedback signal lost.
The actual running time of the
inverter is above the internal
setting
setting running time.
The inverter will report the
underload pre-alarm according to
the set value.
Possible cause
Fault occurs to
70
Remedy action
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
Check the external device input
1. Set correct baud rate.
2. Check the communication
the
connection distribution
3. Set correct communication
address.
4. Check earthing connections
and cable screening.
1. Press STOP/RST to reset
2. Change the main control
panel.
1. Check the PID feedback
signal.
2. Check the PID feedback
source.
Ask for the supplier and adjust
the setting running time.
Check the load and the
underload pre-alarm point.
