Fault info
Reason Solution
PE Fault
The PE cable is not connected or
there is a problem with the system
settings.
When the PE cable is not connected,
check whether the TT, IT, TN systems
settings are set to the expected results. If
the settings is successful, check whether
the PE cable is connected.
Over-Voltage Fault
Single phase: input voltage is
detected to be greater than
276VAC
±
3VAC for 5 seconds:
Three phase: input voltage is
detected to be greater than
460VAC
±
3VAC for 5 seconds.
Single phase recovery logic: when the
voltage is lower than 254
±
3VAC, the
state of plugging in will be recovered
；
Three phase recovery logic: when the
voltage is lower than 450
±
3VAC, the
state of plugging in will be recovered.
Under-Voltage Fault
Single phase: input voltage is
lower than 154VAC
±
3VAC for 5
seconds;
Three phase: input voltage is lower
than 340VAC
±
3VAC for 5
seconds.
Single phase recovery logic: if the
voltage is higher than 164
±
3VAC, the
state of plugging in will be recovered;
Three phase recovery logic: if the
voltage is higher than 350
±
3VAC, the
state of plugging in will be recovered.
Metering Communication
Failure
There is a communication problem
between the metering chip and the
main chip.
Restart the charger 3 times in a row to
see if the fault eliminated. If it is not
eliminated, the metering chip is
damaged, return the charger to factory
for repair.
