6. メンテナンス

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

• デバイスを清潔に保ち、ほこりやごみが付かないようにしてください。
• Periodically inspect wiring connections for tightness and signs of wear.
• 過熱を防ぐために、デバイスの周囲に十分な換気を確保してください。

7。 トラブルシューティング

デバイスが期待どおりに機能しない場合は、次の点を考慮してください。

• ディスプレイなし/電源なし: 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.
• 位相障害: The device automatically detects and responds to phase failures, initiating a cut-off and auto-reset once the phase is restored.
• 間違った読み方: If readings appear inaccurate, consider performing a manual error calibration as described in Section 5.3.
