ABL Wallbox eMH3 - Error Codes for RFID Module Operation; Disruptions to the Operation of the Charging Station and Solutions

resolvIng errors
20
For most error states, the wallbox reinitiates the charging procedure, checking com-
munications with the vehicle. However, in practice, it is, in case of an error, advis-
able to manually reinitiate the charging procedure by unplugging and reconnecting the
cable as not all errors can be resolved by the automatic restart.
WARNING!
If the wallbox continues to show error messages while charging the ve-
hicle, please always contact the service partner for your vehicle. It is pos-
sible that your vehicle must be repaired or the wallbox needs to be re-
placed before the vehicle can be charged again using the wallbox.
Error codes for RFID module operation
Under some circumstances, malfunctions and disruptions may occur during login at
the RFID module that prevent the proper charging of the vehicle according to IEC
61851.1 Mode 3. The eMH3 recognizes potential errors during user login and displays
error codes via the indicator LEDs at the front of the RFID module.
The RFID module does not recognize the ID tag card: Charg-
ing is refused.
Green LED flashes once,
blue LED is ON
The ID tag card is rejected by the RFID module: Charging is
refused.
Green LED is OFF,
blue LED flashes once.
• Should the ID tag card not have been registered with the RFID module previously,
proceed as described from page 15 onwards to register it with the RFID module.
• You may first need to reset the RFID module in order to re-register the ID tag cards.
This is described in detail in section page 15 and following.
Disruptions to the operation of the charging station and solutions
For safe operation, the eMH3 has integrated DC fault current detection and two resid-
ual current circuit breakers (RCCB), which detect residual currents that may occur and
disconnect the entire wallbox from the electricity supply for your personal protection.
The RCCBs are mounted flush with the internal electronic components cover and can
be operated after opening the housing cover.
To take suitable measures and restore operation in case of malfunction, you must first
clearly identify the type of error.
