RESOLVING ERRORS

Error messages during operation with the vehicle
In some circumstances, malfunctions and disruptions may occur that prevent the
proper charging of the vehicle according to IEC 61851.1, Mode 3. The wallbox detects
possible errors on the part of the vehicle independently and shows them using the
indicator LEDs.
To represent certain errors, the indicator LEDs will flash in a specific, repeating pattern.
The following error codes are displayed:
LED-SEQUENCE
(FLASHING)
ERROR DESCRIPTION
The vehicle makes an unauthorized demand on the
charging procedure
Communication with the vehicle is disrupted
A DC fault current has been detected
The EVSE 803/813 reinitiates the charging procedure every 30 seconds, checking com-
munications with the vehicle. If the error recurs, the indicator LEDs continue to show
the error code: No charging occurs in this operating state.
CAUTION!
If the wallbox continues to show error messages during operation with the
vehicle, please always contact your service partner for the vehicle. It is pos-
sible that maintenance must be carried out before the vehicle can be charged
again using the EVSE 803/813.
Operational disruptions and solutions
For safe operation, the eMH1 is equipped with DC fault current detection and a resid-
ual current circuit breaker (RCCB), which detect residual currents that may occur and
disconnect the entire wallbox from the electricity supply for your personal protection.
The RCCB is located under the lockable cover shield: This ensures that it can only be
operated by authorized users.
To take suitable measures and restore operation in case of malfunction, you must first
clearly identify the type of error.
