Figur 1: Front view of the Tomzn TOVPD1-80-EC protection device. Note: The image displays model TOVPD1-60-EC, but the instructions apply to the TOVPD1-80-EC model with an 80 Amper rating.
The device includes input terminals (IN) and output terminals (OUT) for electrical connections, along with a power indicator and status LEDs for over-voltage (>V), under-voltage (<V), and over-current (>A).
4. Installasjon
The TOVPD1-80-EC device is designed for DIN rail mounting (35mm). Follow these steps for proper installation:
- Strømfrakobling: Before starting, ensure the main power supply to the circuit is completely disconnected to prevent electrical shock.
- Montering: Snap the device onto a standard 35mm DIN rail in your electrical panel.
- Kabling:
- Connect the incoming live (L) and neutral (N) wires from the power source to the "IN" terminals of the device.
- Connect the outgoing live (L) and neutral (N) wires to the load (appliances/circuit) from the "OUT" terminals of the device.
- Sørg for at alle koblinger er tette og sikre.
- Bekreftelse: Double-check all wiring connections for correctness and security.
- Strømgjenoppretting: Restore power to the circuit. The device will power on and display the current voltage og aktuelle avlesninger.
5. Operating Instructions and Settings
The device displays real-time voltage and current. Use the control buttons to adjust protection parameters.
5.1. Knappefunksjoner
- Strømknapp: Turns the device ON/OFF (if applicable, or for display cycling).
- SET -knapp: Enters/exits setting mode and cycles through parameters.
- Pil opp-knapp (▲): Increases parameter values.
- Pil ned-knapp (▼): Decreases parameter values.
5.2. Justering av parametere
To adjust a parameter:
- Trykk på SETT -knappen for å gå inn i innstillingsmodus. Den første parameteren vil blinke.
- Pressen SETT repeatedly to cycle through the available parameters (e.g., Over-voltage protection threshold, Under-voltage protection threshold, Over-current protection threshold, recovery delays, etc.).
- When the desired parameter is flashing, use the ▲ (Opp og ▼ (Down) buttons to adjust its value.
- After setting the value, wait a few seconds for the device to automatically save the setting and exit the setting mode, or press SETT igjen for å gå til neste parameter.
5.3. Parameter Ranges and Default Values (for 220V/80A model)
| Parameter | Justerbar rekkevidde | Standardverdi |
|---|---|---|
| Over-voltage beskyttelse (UVP) | 230V ~ 300V (OFF) | 270V |
| Over-voltage Recovery (UVR) | 225V ~ 295V | 250V |
| UVP Action Time | 0.1 s ~ 30 s | 0.5 s |
| UVP Recovery Delay | 1 s ~ 500 s | 30 s |
| Under-voltage Protection (LVP) | 140V ~ 210V (OFF) | 170V |
| Under-voltage Recovery (LVR) | 145V ~ 215V | 190V |
| LVP Action Time | 0.1 s ~ 30 s | 0.5 s |
| LVP Recovery Delay | 1 s ~ 500 s | 30 s |
| Over-current Protection (OCP) | 1A ~ 80A (adjustable) | 40A (Note: Default may vary based on specific model variant.) |
| OCP Action Time | 0.1 s ~ 30 s | 0.5 s |
| OCP Recovery Delay | 1 s ~ 500 s | 30 s |
| Power-on Delay Time | 1 s ~ 500 s | 10 s |
Note: The over-current adjustment range is inferred to be up to 80A for the TOVPD1-80-EC model, although the provided description mentions 40A and 63A variants. Always refer to the specific markings on your device.

To inquire about past error events, press and hold the ▲ (Up) button for more than 12 seconds. The device will display error codes or logs if available.
6. Vedlikehold
- Inspiser enheten regelmessig for tegn på fysisk skade eller løse forbindelser.
- Hold enheten ren og fri for støv. Bruk en tørr, myk klut til rengjøring.
- Ikke bruk skurende rengjøringsmidler eller løsemidler.

7. Feilsøking
| Problem | Mulig årsak | Løsning |
|---|---|---|
| Enheten slås ikke på | No power supply; incorrect wiring; internal fault. | Check main power supply. Verify wiring connections. If problem persists, contact support. |
| Device trips frequently | Protection thresholds set too low; actual voltage/current exceeds limits. | Adjust protection parameters (UVP, LVP, OCP) to appropriate levels. Check load for faults. |
| Displayet viser feilkode | Internal error or specific fault detected. | Refer to the error inquiry function (Section 5.5) for details. If unknown, contact support. |
| Device does not recover automatically | Automatic recovery feature disabled or recovery delay too long. | Ensure automatic recovery is enabled in settings. Check recovery delay times. |
