Setup Instructions
1. Safety Precautions
- Ensure power is OFF before installation to prevent electric shock.
- Installation should be performed by a qualified electrician.
- Verify correct voltage and current ratings before connecting the device.
2. Physical Installation (Din Rail Mounting)
The ATORCH AT2P meter is designed for universal 35mm standard Din Rail mounting. No screws are required for installation.
- Locate a suitable 35mm Din Rail in your electrical panel.
- Align the meter's clip with the Din Rail.
- Press firmly until the meter snaps securely onto the rail.
3. Wiring Instructions
The meter supports two wiring modes due to its screen flip function (top-in/bottom-out or bottom-in/top-out). Always connect the Neutral (N) and Live (L) lines correctly.
Standard Wiring (Top-in, Bottom-out)
- Connect the incoming Neutral (N-IN) to the N-IN terminal and incoming Live (L-IN) to the L-IN terminal at the top of the meter.
- Connect the outgoing Neutral (N-OUT) to the N-OUT terminal and outgoing Live (L-OUT) to the L-OUT terminal at the bottom of the meter.
- If your model includes leakage protection, connect the leakage protection induced current coil around the Live (L) line. The coil connects to terminals 24 and 25.
Alternative Wiring (Bottom-in, Top-out)
The screen flip function allows for flexible wiring. If you prefer bottom-in/top-out wiring, simply rotate the screen 180 degrees after physical installation.
4. Tuya WiFi Connection
- Download the "Smart Life" or "Tuya Smart" app from your mobile app store.
- Register or log in to your account.
- Power on the AT2P meter. The startup screen will show "Internet of Things control monitor" and "Waiting in EZ mode".
- In the app, tap "+" to add a device.
- Follow the in-app instructions to connect the meter to your WiFi network. This typically involves entering your WiFi password.
- Once connected, the meter display will show "Network successfully".
Operation
1. Display Interface
The meter's display shows various real-time electrical parameters. The main measurement display area is movable via a scroll bar.
- Main measurement display area: Shows Voltage (V), Current (A), Power (W), Energy (kWh), Frequency (Hz), Power Factor (PF).
- Power Indicator: Indicates power status.
- WiFi Connect indicator: Shows WiFi connection status.
- "+" Key: Long press to turn ON/OFF. Click to move screen data parameters downward.
- "-" Key: Long press to turn ON/OFF. Click to move screen data parameters upward.
- "M" Key: Short press in the function test interface to set parameter values. Long press to enter the background settings.
2. Remote Control via Mobile App
Once connected to the Tuya WiFi network, you can control and monitor the device remotely using the mobile app.
- Device ON/OFF: Control the power supply remotely.
- Timing Function: Set schedules for automatic power ON/OFF.
- Countdown Function: Set a countdown timer for power ON/OFF.
- Energy Monitoring: View real-time and historical data for voltage, current, power, and energy consumption.
- Power Graph: Visualize power consumption trends over time.
3. Protection Functions
The AT2P meter includes several built-in protection functions to safeguard your electrical system and connected appliances.
- Over-voltage protection (OVP): Automatically cuts off power if voltage exceeds a set threshold.
- Over-current protection (OCP): Automatically cuts off power if current exceeds a set threshold.
- Over-power protection (OPP): Automatically cuts off power if total power consumption exceeds a set threshold.
- Under-voltage protection (UVP): Automatically cuts off power if voltage drops below a set threshold.
- Leakage protection: (For models with leakage protection coil) Detects leakage current and cuts off power.
- Timing/countdown protection: Configurable power ON/OFF schedules and timers.
- Over-voltage and under-voltage delay recovery: Prevents rapid cycling of power after a protection event.
4. Electricity Price Settings
The meter allows for free setting of peak and valley electricity prices, as well as ladder electricity prices, to meet different needs.
- Single Price Mode: Only single-rate electricity price can be set to calculate the electricity charge.
- Step Price Mode: Three kinds of tariff coefficients can be set. For example, ≤200kWh: 1.00, >200kWh: 1.50. When the power reaches the corresponding value, it calculates different electricity charges.
- Peak-Valley Price Mode: The 24-hour system sets different electricity prices in sections. The time section and electricity price parameters can be set via the app.
5. Power Calculation Formula
The active power (P) is calculated using the formula: P = I * U * COS φ
Where:
- P = Active Power (Watts)
- I = Current (Amperes)
- U = Voltage (Volts)
- COS φ = Power Factor (PF Value)
Maintenance
- Keep the device clean and free from dust.
- Do not expose the device to excessive moisture or extreme temperatures.
- Regularly check wiring connections for tightness and signs of wear.
- Firmware updates will be released irregularly for lifetime free upgrade functionality via WiFi. Ensure your device is connected to the internet for updates.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on | No power supply; incorrect wiring. | Check main power supply. Verify N-IN and L-IN connections. |
| No WiFi connection | Incorrect WiFi password; meter too far from router; router issues. | Re-enter WiFi password in app. Move meter closer to router. Restart router. Ensure 2.4GHz WiFi network is used. |
| Readings are incorrect or zero | Incorrect current transformer (CT) connection; wiring error. | Ensure CT is correctly installed around the Live (L) wire and connected to the meter. Verify all wiring connections. |
| Protection function trips frequently | Protection thresholds set too low; actual load exceeds limits. | Review and adjust OVP, OCP, OPP, UVP, or leakage protection thresholds in the app or device settings. Reduce connected load if necessary. |
| Remote control not working | No internet connection; app issues. | Check WiFi connection status on the meter and in the app. Restart the app. |
User Tips
- For accurate energy monitoring, ensure the current transformer (CT) is installed correctly and securely around the live wire.
- Utilize the timing and countdown functions in the mobile app to automate appliance control and save energy.
- Regularly check the power graph in the app to identify peak consumption times and optimize usage.
- If using the RS485 interface, ensure proper configuration of equipment address and baud rate for communication with a computer system.
- Keep the firmware updated via WiFi for the latest features and performance improvements.
