4. Setup and Installation
The TOVAE2-100C meter is designed for standard 35mm DIN rail installation. Follow these steps for proper setup:
- Power Disconnection: Before starting any installation, ensure that the main power supply to the circuit is completely disconnected to prevent electric shock.
- Mounting: Attach the meter to a standard 35mm DIN rail. The meter features a clip on the back for easy and secure mounting.
- Wiring: Refer to the wiring diagram below for correct connections.
- Connect the Live (L) input wire to the 'L↑' terminal.
- Connect the Neutral (N) input wire to the 'N' terminal.
- Connect the Live (L) output wire (to the load) to the 'L↓' terminal.
- Ensure all connections are tight and secure.
- Power Connection: Once all wiring is complete and verified, restore power to the circuit. The meter should power on and display readings.
5. Operating Instructions
The TOVAE2-100C meter provides real-time display of voltage, current, and energy consumption.
- Display Readings: The meter simultaneously displays Voltage (V), Current (A), and Energy (kWh) on its multi-color digital screen.
- Energy Display Cycle: The energy consumption (kWh) reading cycles between "energy-low" and "energy-high" digits every five seconds to show the full value (e.g., 00.00 and 99.99 for 99999.9kWh).
- Resetting Energy (kWh) Reading: To reset the accumulated energy (kWh) reading, press and hold the 'CLR' button located on the top front of the meter until the kWh value resets to zero.
6. Maintenance
- Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
- Do not use abrasive cleaners or solvents.
- Ensure the operating environment is within the specified temperature and humidity ranges.
- Regularly check wiring connections for tightness and signs of wear or damage.
- The meter is constructed with high-grade PC flame-retardant material for durability and safety.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Power off | No power supply; Incorrect wiring; Loose connections. | Check power source; Verify wiring according to diagram; Tighten all terminals. |
| Incorrect readings (V, A, kWh) | Incorrect wiring; Device malfunction. | Double-check wiring; Compare readings with another calibrated meter. If persistent, contact support. |
| Energy (kWh) not resetting | CLR button not held long enough; Button malfunction. | Press and hold the 'CLR' button for several seconds until reset. |
8. User Tips
- For optimal readability, ensure the meter is installed at eye level. The BTN wide viewing angle LCD provides clear visibility from various angles.
- Regularly check the energy (kWh) reading to monitor consumption patterns and identify potential energy savings.
- The meter's plug-and-play design with standard connectors helps avoid wrong connections and short circuits, but always double-check wiring.
