6. Wartung
The EARU-1008 is designed for minimal maintenance. However, periodic checks are recommended:
- Halten Sie das Gerät sauber und frei von Staub und Schmutz.
- Überprüfen Sie die Kabelverbindungen regelmäßig auf festen Sitz und Anzeichen von Verschleiß.
- Sorgen Sie für ausreichende Belüftung rund um das Gerät, um eine Überhitzung zu vermeiden.
7. Fehlerbehebung
Falls das Gerät nicht wie erwartet funktioniert, beachten Sie Folgendes:
- Kein Display/Keine Stromversorgung: Check the main power supply and all wiring connections.
- Schutzauslösung: 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.
- Falsche Messwerte: If readings appear inaccurate, consider performing a manual error calibration as described in Section 5.3.
