6. Vedligeholdelse

The EARU-1008 is designed for minimal maintenance. However, periodic checks are recommended:

• Hold enheden ren og fri for støv og snavs.
• Periodically inspect wiring connections for tightness and signs of wear.
• Sørg for tilstrækkelig ventilation omkring enheden for at forhindre overophedning.

7. Fejlfinding

Hvis enheden ikke fungerer som forventet, skal du overveje følgende:

• Intet display/Ingen strøm: Check the main power supply and all wiring connections.
• Beskyttelsestur: Identify the active protection indicator (>V, <V, >I). Check the corresponding voltage or current levels. The device will automatically reset once conditions return to normal, based on configured recovery delays.
• Phase Failure: The device automatically detects and responds to phase failures, initiating a cut-off and auto-reset once the phase is restored.
• Forkerte aflæsninger: If readings appear inaccurate, consider performing a manual error calibration as described in Section 5.3.
