6. Troubleshooting
The LED display will indicate errors if a problem occurs during charging. Refer to the display for specific error codes or messages.
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not starting | Loose connection, no power, vehicle not ready to charge. | Ensure all connections are secure. Check power outlet. Verify vehicle charging settings. |
| Error message on display | Internal fault, overcurrent, overvoltage, grounding issue, overtemperature. | Note the error code. Disconnect and reconnect the charger. If the error persists, press the button on the control box for 5 seconds to reset the charging cable. If the issue continues, contact support. |
| Slow charging | Low current setting, vehicle limitation, power supply issue. | Adjust the current setting to a higher amperage (e.g., 16A) if your power supply and vehicle support it. Consult your vehicle's manual. |
| Charger feels hot | Normal operation under load, or potential overtemperature. | Some warmth is normal. If the display shows an overtemperature error, disconnect the charger and allow it to cool down in a well-ventilated area before attempting to charge again. |
