OCPP status notification error messages
info
Error activation message is the message that is sent when the error occurred. Error resolution message (if any) is sent when the error is corrected. Some errors may be corrected by external events during operation (e.g. temperature is normal again), while some may be resolved after a reset, power cycle or replacement of a faulty part.
| OCPP Error code | Error activation message | Error resolution message | Transaction and charging is stopped | Notes | Corrective actions |
|---|---|---|---|---|---|
| groundFailure | Residual current detected via sensor | Residual current situation resolved | Yes | Internal RCMB device (yellow coil). This detects also DC residual current. | The safety mechanism is reset to its original state every time the cable is unplugged from the chargepoint. Otherwise the error is automatically reset after a delay of 10 seconds if the EV was unplugged. In case the RCMB version is older than or equal to D0469, the delay is 15 minutes. If the problem persists, please check the yellow current transformer (coil) and its connection. |
