8. Fejlfinding
Hvis enheden ikke fungerer som forventet, skal du overveje følgende:
- Ingen skærm/strøm: Kontroller hovedstrømforsyningen, og sørg for, at alle ledningsforbindelser er sikre.
- Hyppig tripping: Verify that the set overvoltage/undervoltage thresholds are appropriate for your electrical system. Excessive voltage fluctuations in your area might require consultation with an electrician.
- Enheden nulstilles ikke: Check the 'Reset Time Setting' parameter. If the fault condition persists, the device will not reset until the condition is cleared.
- Forkert bindtage læsning: Ensure proper wiring and that the device is correctly rated for your supply voltage.
For issues not resolved by these steps, contact qualified technical support.
