GE EV Charging Station User Manual 51 of 86
The EVSE internally monitors its operating performance. If there is a failure of its performance, the
status indicator on the EVSE will indicate RED and lockout.
Overvoltage/Undervoltage Faults:
The EVSE monitors line voltage and cuts power to the EV if the voltage goes out of range. After 1
minute the EVSE rechecks the voltage and will automatically re-enable charging if the voltage comes
back within acceptable range. The status indicator will turn RED as long as charging is interrupted.
Overload Fault:
The EVSE monitors the current being drawn by the EV. If this current exceeds the capability of the
EVSE fuse, charging will be interrupted and the status indicator will show turn RED. This fault can be
cleared by disconnecting from the EV.
