- Connect the incoming live (phase) wire to the L-IN terminal.
- Connect the incoming neutral wire to the N-IN terminal.
- Connect the outgoing live (phase) wire to the L-OUT terminal, leading to your load.
- Connect the outgoing neutral wire to the N-OUT terminal, leading to your load.
- Ensure all connections are tight and correct according to the wiring diagram provided with the product.
- Power Restoration: Once all connections are verified, restore the main power supply. The device's LCD screen should illuminate.
- App Setup: Download the designated mobile application (e.g., Tuya Smart or Smart Life, as commonly used for such devices) from your smartphone's app store. Follow the in-app instructions to add and configure the TOMPD-63SW device to your Wi-Fi network. This typically involves putting the device into pairing mode (refer to the device's specific button sequence for pairing).
7. Operation
The TOMPD-63SW offers both local display and remote control/monitoring capabilities.
7.1. LCD Display
The integrated LCD screen provides real-time information:
- Voltage (V): Displays the instantaneous line voltage.
- Current (A): Shows the instantaneous current flowing through the circuit.
- Power (W/kW): Indicates the instantaneous active power consumption.
- Energy (kWh): Accumulates total energy consumption.
- Status Indicators: May show indicators for Wi-Fi connectivity, protection status (e.g., over-voltage, under-voltage, leakage current trip).
7.2. Mobile Application Control
After successful app setup, you can:
- Remote Monitoring: View real-time voltage, current, power, and energy consumption from anywhere.
- Remote Control: Turn the connected circuit ON or OFF remotely (if this feature is enabled for the specific model).
- Protection Settings: Adjust parameters for over-voltage, under-voltage, and leakage current protection thresholds.
- Historical Data: Access and analyze historical energy consumption data and event logs (e.g., protection trips).
- Scheduling: Set schedules or timers for the device to turn ON/OFF automatically.
8. Maintenance
The Tomzn TOMPD-63SW is designed for minimal maintenance. However, regular checks can ensure optimal performance and safety:
- Cleaning: Periodically clean the device's exterior with a dry, soft cloth. Do not use abrasive cleaners or solvents.
- Connection Check: Annually, or as needed, verify that all wiring connections are secure and free from corrosion. Ensure power is disconnected before performing this check.
- Firmware Updates: Check the mobile application periodically for any available firmware updates for the device. Updates can improve performance and add new features.
9. Troubleshooting
If you encounter issues with your TOMPD-63SW, refer to the following common problems and solutions:
- Device Not Powering On:
- Check the main power supply and circuit breaker.
- Verify all wiring connections (L-IN, N-IN) are correct and secure.
- No Wi-Fi Connection:
- Ensure your Wi-Fi network is 2.4GHz (5GHz networks are typically not supported by these devices).
- Check the Wi-Fi signal strength at the device's location.
- Restart your Wi-Fi router.
- Attempt to re-pair the device with the mobile application (refer to app instructions for pairing mode).
- Device Trips Frequently:
- Check the load connected to the device; it might be drawing excessive current or experiencing a fault.
- Review the over-voltage, under-voltage, and leakage current protection settings in the mobile application. They might be set too sensitively.
- Inspect the electrical system for actual faults (e.g., ground fault, short circuit).
- Inaccurate Readings:
- Ensure wiring connections are correct and tight.
- Compare readings with a calibrated multimeter if possible.
If the problem persists, contact customer support or a qualified electrician.
