| Common Malfunctions |
Troubleshooting / Method of Exclusion |
| When the connector is inserted, the interface does not show a connection or the message “Please start charging by swiping your card.” |
Verify the connector is fully inserted and the lock is engaged. Ensure a secure connection between the connector and the vehicle. |
| After swiping the card to start charging, the session stops by itself after a while. |
This is usually a communication issue. Note any error message, try another connector, and if it persists report it to the manufacturer. |
| Connector remains locked after charging (locking issue). |
Complete settlement using the same card that started the session. If it remains locked, use that terminal to unlock after settlement or contact service. |
| “Jumping gun” (intermittent disconnection) during charging. |
Ensure the IC card has sufficient balance before starting. If balance becomes insufficient during charging, the session will terminate automatically. |
| After charging, the connector is locked and cannot be removed. |
Try starting a short charging cycle and then stop to trigger release. If it still won’t unplug, contact the manufacturer for maintenance. |
| Ammeter does not display current after starting charge. |
Check the meter wiring for reversed phase/neutral or other miswiring and correct it if necessary. |
| Display does not light up after power on. |
If LEDs show power but the display remains blank, replace the display module. |
| Grounding abnormality / not grounded. |
Verify proper grounding. With correct earth connection: (1) when the connector is absent the 12V auxiliary indicator should be blue; (2) when inserted the 6V auxiliary indicator should be green. |
