How do I troubleshoot a residential EV charging station, EV230WS?
Issue:
An EV station is showing a detected fault indicator lamp lit.
Product Line:
PTEVC - Electrical Vehicle
Resolution:
The EVlink charging station detects several different types of faults. For residential (indoor) rated stations, the HMI (human machine interface) has 8 LED segments. Each of these segments, when lit red, indicates a different detected fault. Many conditions can be reset by powering the unit off by turning off the supplying 40 A circuit breaker.
