Característiques principals:

• Restabliment automàtic: Automatically restores power when voltage returns to normal after an anomaly.
• Multifunctional Protection: Combines over-voltage, baix voltage, over-current, three-phase unbalance, phase sequence, and phase-break protection.
• Pantalla LCD: Clear display for real-time voltage and current readings, and easy parameter adjustment.
• Fault Inquiry: Allows users to check fault history.
• Paràmetres ajustables: Customizable protection values and recovery times.

2. Configuració i instal·lació

2.1 Precaucions de seguretat

• Assegureu-vos que tot l'alimentació estigui desconnectada abans de la instal·lació o el manteniment.
• La instal·lació l'ha de fer un electricista qualificat.
• Verify correct wiring according to the provided diagrams and local electrical codes.
• No feu funcionar el dispositiu si sembla que està danyat.

2.2 Instruccions de muntatge

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 Restauració de la configuració de fàbrica

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. Manteniment

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

• Neteja: Keep the device clean and free from dust. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
• Comprovació de la connexió: Inspeccioneu periòdicament les connexions del cablejat per assegurar-vos que estiguin ben fixades i que no presentin corrosió.
• Condicions ambientals: Assegureu-vos que l'entorn de funcionament es mantingui dins dels rangs de temperatura i humitat especificats.

5. Solució De Problemes

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

• Sense alimentació/Pantalla apagada: Check incoming power supply and wiring connections. Ensure the device is correctly installed.
• Sortides freqüents: Review the set protection parameters (overvoltage, minvartage, overcurrent) to ensure they are appropriate for your electrical system. Check for actual power fluctuations or overloads.
• Lectures incorrectes: 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.
