6. Manutenção

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

• Mantenha o dispositivo limpo e livre de poeira e detritos.
• Periodically inspect wiring connections for tightness and signs of wear.
• Garanta ventilação adequada ao redor do dispositivo para evitar superaquecimento.

7. Solução De Problemas

Se o dispositivo não estiver funcionando como esperado, considere o seguinte:

• Sem imagem/Sem energia: 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.
• Leituras incorretas: If readings appear inaccurate, consider performing a manual error calibration as described in Section 5.3.
