6. Entretien
The EARU-1008 is designed for minimal maintenance. However, periodic checks are recommended:
- Gardez l'appareil propre et exempt de poussière et de débris.
- Periodically inspect wiring connections for tightness and signs of wear.
- Assurez une ventilation adéquate autour de l'appareil pour éviter toute surchauffe.
7. Dépannage
Si l'appareil ne fonctionne pas comme prévu, tenez compte des points suivants :
- Pas d'affichage/Pas d'alimentation : Check the main power supply and all wiring connections.
- Protection Trip: 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.
- Lectures incorrectes : If readings appear inaccurate, consider performing a manual error calibration as described in Section 5.3.
