Troubleshooting

If a fault occurs, the fault symbol on the LED display panel lights up or flashes. The wallbox cannot be used until the fault has been rectified.

If the wallbox has been set up in the KOSTAL Smart Energy Meter, the event messages are displayed in KSEM and in the KOSTAL Solar Portal. Explanations of the event messages can be found on the following pages.

Faults not displayed:

In the event of major interference on the grid side, the wallbox may restart in order to reinitialise all system components. A charging process that had previously been started is then resumed. If the error occurs frequently, check the surroundings of the installation for EMC interference.
Lock Mode cannot be cancelled
If the wallbox is in Lock Mode (only possible with KOSTAL Smart Energy Meter with convenience functions) and this mode can no longer be cancelled via the KOSTAL Smart Energy Meter, the wallbox must be restarted via the line circuit breaker.

Red LED flashing:

The fault can be remedied by the user or the operator.

Potential faults:

Maximum charging current exceeded by electric vehicle
DC residual current
Excess temperature

When troubleshooting, work in the following order:

Stop charging process and disconnect the charging cable.
Wait approx. 20 seconds.
Reconnect charging cable and start charging process.
If necessary, disconnect charging cable and wait until the wallbox has cooled down.

If you are not able to rectify the fault, please contact your service partner or our service hotline.

Red LED lit up:

The fault can only be rectified by an electrician.
