5.1 Wiring Diagram

The SVP-916 is designed for easy integration into your electrical system. Follow the wiring diagram below carefully:

Figure 5.1: Wiring diagram for the SVP-916, showing connections with a power switch and an air circuit breaker.

• Input Connections: Connect the incoming live (L) wire to the 'IN' terminal and the incoming neutral (N) wire to the 'N' terminal on the top of the device.
• Output Connections: Connect the outgoing live (L) wire to the 'L' terminal and the outgoing neutral (N) wire to the 'OUT' terminal on the bottom of the device.
• Integration: The device should be installed in series with the circuit it is protecting, typically after the main power switch or circuit breaker and before the load.
• Secure Connections: Ensure all wire connections are tight and secure to prevent loose contacts and potential hazards.

5.2 Mounting

The SVP-916 is designed for DIN rail mounting, making it suitable for installation inside standard electrical distribution boxes or control panels.

6. Operating Instructions

6.1 Display Readings

Once powered on, the dual LED display will show the real-time voltage (red display) and current (green display) of the circuit. The working indicators (OV, UV, OC) will illuminate if a protection event occurs.

6.2 Adjusting Protection Parameters

The SVP-916 allows you to set custom thresholds for overvoltage, undervoltage, and overcurrent protection. Follow these steps to adjust the parameters:

1. Enter Setting Mode: Press and hold the SET button for approximately 3-5 seconds until the display starts flashing, indicating you are in setting mode.
2. Navigate Parameters: Briefly press the SET button to cycle through the adjustable parameters (e.g., Overvoltage Threshold, Undervoltage Threshold, Overcurrent Threshold, Recovery Delay Time, etc.). Each parameter will flash when selected.
3. Adjust Values: Use the ▲ (Up) and ▼ (Down) buttons to increase or decrease the value of the currently selected parameter.
4. Save Settings: After adjusting a parameter, briefly press the SET button to confirm the value and move to the next parameter. To exit the setting mode and save all changes, press and hold the SET button again for 3-5 seconds, or wait for the device to automatically exit after a period of inactivity.

Refer to the device's specific parameter codes and ranges, which may be printed on the device itself or provided in supplementary documentation, for precise adjustment values.

7. Maintenance

The SINOTIMER SVP-916 is designed for long-term, maintenance-free operation. However, periodic checks can help ensure its continued reliability:

• Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
• Connection Check: Periodically inspect the wiring connections to ensure they remain tight and free from corrosion.
• Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges.
• Functionality Test: If possible and safe to do so, periodically test the protection functions by simulating an overvoltage or overcurrent condition (e.g., using a controlled test setup) to confirm the device trips as expected.

NOTE: Any internal repairs or servicing must be performed by authorized personnel only.
