1. Introducció
The SINOTIMER SVP-977 is a three-in-one multi-function device designed for home usage, providing comprehensive protection against over-voltage, baix voltage, and over-current conditions in single-phase AC 230V, 50/60Hz electrical systems. It also features power monitoring capabilities, displaying voltage, current, and energy consumption (kWh) on an LCD screen. This device is primarily used for residential household box entry or for protecting distribution lines of single-phase electrical equipment. Its key function is to instantly cut off the power supply when abnormal voltage or current conditions occur, safeguarding connected electrical equipment from damage. Once the circuit voltage returns to normal, the protector automatically restores power.

7. Solució De Problemes
If you encounter issues with your SVP-977, consider the following:
- El dispositiu no s'encén: Check the main power supply and ensure all wiring connections are correct and secure. Verify the input voltage is within the operational range.
- Frequent Tripping: Review your set protection values (over-voltage, baix voltage, over-current). They might be set too sensitively for your electrical environment. Adjust the delay times (action time, recovery delay) to prevent nuisance tripping.
- Lectures incorrectes: While the device is calibrated, significant discrepancies might indicate a wiring issue or a faulty unit. Ensure proper connections.
- Settings Not Saving: Ensure you press the SET button until "END" appears and then press it one more time to confirm and save the settings.
- No Automatic Recovery: Check the recovery delay time setting. If set to a long duration, the device will wait before restoring power.
If problems persist after checking these points, please consult a qualified electrician or contact customer support.
8. Consells d'usuari
- Placement in Circuit: The SVP-977 can be installed after a Residual Current Device (RCD) or Residual Current Breaker with Overcurrent protection (RCBO) for comprehensive circuit protection.
- Voltage Estabilització: This device is a protector, not a voltage stabilizer. It will cut off power if voltage goes outside the set limits, but it does not actively regulate or stabilize the voltage.
- Settings Retention: All configured settings are retained even after a power outage, so you do not need to reconfigure them every time power is lost.
- KWH Reset: The temporary kWh reading can be reset. Refer to the operation section for detailed instructions on navigating the settings menu.
- Recovery Delay: The device includes an adjustable recovery delay time (from 2 to 600 seconds) which is useful to prevent rapid cycling of power to appliances after a fault, allowing them to stabilize.
