To inquire about past fault conditions, press and hold the UP arrow key for more than 12 seconds.

Manual Switch

To turn off the protection function, press the Power button (circular icon) while in the setting state.

9. Troubleshooting

10. User Tips

• Verify Auto-Recovery Settings: If your device sometimes auto-recovers and sometimes doesn't after a trip, double-check your 'Power-on delay time' and 'Recovery delay time' settings (A1, A4, A8, A11) to ensure they are configured as desired for consistent behavior.
• Regular Checks: Periodically check the real-time voltage and current displays to monitor your electrical system's stability.
• Calibration: If you suspect the voltage or current readings are inaccurate, utilize the calibration functions (A14, A15) for precise measurements.

11. Maintenance

The TOMZN protector is designed for minimal maintenance. However, regular checks can ensure its longevity and optimal performance:

• Cleaning: Keep the device clean and free from dust. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
• Connection Checks: Periodically inspect wiring connections to ensure they remain tight and secure. Loose connections can lead to overheating or intermittent operation.
• Environmental Conditions: Ensure the device is operating within its specified environmental conditions (temperature, humidity) to prevent premature failure.

12. Warranty and Support

For warranty information, technical support, or service inquiries, please refer to the product packaging or contact your retailer. Keep your purchase receipt as proof of purchase.
