Caratteristiche principali:

• Ripristino automatico: Ripristina automaticamente l'alimentazione quando il volumetage returns to normal after an anomaly.
• Protezione multifunzionale: Combines over-voltage, sotto-volumetage, over-current, three-phase unbalance, phase sequence, and phase-break protection.
• Schermo LCD: Clear display for real-time voltage and current readings, and easy parameter adjustment.
• Richiesta di guasti: Allows users to check fault history.
• Parametri regolabili: Customizable protection values and recovery times.

2. Configurazione e installazione

2.1 Precauzioni di sicurezza

• Prima dell'installazione o della manutenzione, assicurarsi che tutta l'alimentazione sia scollegata.
• L'installazione deve essere eseguita da un elettricista qualificato.
• Verify correct wiring according to the provided diagrams and local electrical codes.
• Non utilizzare il dispositivo se appare danneggiato.

2.2 Istruzioni di montaggio

The STVP-936 is designed for rail vertical installation. Ensure adequate space for ventilation and wiring connections. Mount the device securely on a standard DIN rail within an electrical enclosure.

3.3 Ripristino delle impostazioni di fabbrica

The device has a function to restore factory default settings. Refer to the specific instructions in the full product manual or contact support for the exact procedure.

4. Manutenzione

The STVP-936 is designed for minimal maintenance. However, periodic checks are recommended to ensure optimal performance and safety:

• Pulizia: Mantenere il dispositivo pulito e privo di polvere. Utilizzare un panno asciutto e morbido per la pulizia. Non utilizzare detergenti liquidi.
• Verifica della connessione: Controllare periodicamente i collegamenti elettrici per assicurarsi che siano saldi e privi di corrosione.
• Condizioni ambientali: Assicurarsi che l'ambiente operativo rimanga entro gli intervalli di temperatura e umidità specificati.

5. Risoluzione Dei Problemi

If the device is not functioning as expected, consider the following common issues:

• Nessuna alimentazione/Display spento: Check incoming power supply and wiring connections. Ensure the device is correctly installed.
• Frequenti inciampi: Review the set protection parameters (overvoltage, sottovoltage, overcurrent) to ensure they are appropriate for your electrical system. Check for actual power fluctuations or overloads.
• Letture errate: Verify wiring. If readings are consistently inaccurate, the device may require professional inspection.
• Device Not Resetting: Check the failure recovery delay time setting. Ensure the fault condition has cleared.

The device also features a fault inquiry function. Consult the full product manual for details on how to access and interpret fault codes.
