If an error occurs, check the nature of the error by referring to the
following “Error Code List” and take appropriate
actions according to instructions by the manufacturer
ERROR
DESCRIPTION
POSSIBLE SOLUTION
ERROR FLAG 0
Lightning protection device failure
Check the SPD and GFCI circuit
ERROR FLAG 1
Insulation detection abnormal
The insulation check on the EV has failed.
Please try to charge different EV.
ERROR FLAG 2
Abnormal communication between
Insulation Monitor and Main Control Board
(CM)
Please check the connection between the IM
and CM boards. Check the LED lights on the
CM and IM
ERROR FLAG 3
Abnormal communication between TR
board and CM board
Please check the connection between the tr
and cm boards. Check the LED lights on the
CM and TR
ERROR FLAG 4
Electronic lock failure
Possible failure of the connector to lock on the
EV or the 24v supply voltage
ERROR FLAG 5
Internal use
Reserved
ERROR FLAG 6
Abnormal communication between DC
meter and main control board (CM)
Please check connection between the DC and
CM boards. Check the LED lights on the CM
and communication lines of the DC meter
FAULT TYPE
SOLUTION
IP address communication failure or Server
Communication Failure
Please check the parameter settings interface IP address
information, such as the corresponding IP address is not correct,
please re-enter the address, restart the charger
AC input over voltage / under voltage
Please check the AC input side if the voltage is too high or too low,
excluding the input exception if there is a fault. Then, check the
parameters, the interface set, and the threshold set to ensure that
are correct
DC output over voltage / over current
Please check whether the output voltage and current are within the
range of parameter settings. If not, please check whether the output
voltage, current is too high, or whether the parameter setting is
reasonable
Card reader failure
The card reader is incorrectly wired, or the card reader is disabled.
Insulation fault
Please check whether the DC bus insulation is normal.
Monitoring board communication failure
Check whether the monitoring board communication line is correct
Charging connector connection failure
Charging connector is disconnected, please check whether the
charging connector is connected properly.
The emergency stop button is pressed
Check whether the emergency stop button is pressed, if it is, inspect
the charger and if everything is normal, release the emergency button
and restore the main breaker
Charging Session shutdown is not successful
MCU board and power module communication failure. Please press
emergency stop button to stop the charging. Check the MCU board
and power module CAN communication bus.
