Figuur 1: Voorkant 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 Ampere gradering.

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. Installasie

The TOVPD1-80-EC device is designed for DIN rail mounting (35mm). Follow these steps for proper installation:

1. Kragontkoppeling: Before starting, ensure the main power supply to the circuit is completely disconnected to prevent electrical shock.
2. Montering: Snap the device onto a standard 35mm DIN rail in your electrical panel.
3. Bedrading:
   • 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.
   • Maak seker dat alle verbindings styf en veilig is.
4. Verifikasie: Dubbelkontroleer alle bedradingsverbindings vir korrektheid en sekuriteit.
5. Kragherstel: Restore power to the circuit. The device will power on and display the current voltage en huidige lesings.

5. Operating Instructions and Settings

The device displays real-time voltage and current. Use the control buttons to adjust protection parameters.

5.1. Knoppie Funksies

• Kragknoppie: Turns the device ON/OFF (if applicable, or for display cycling).
• SET -knoppie: Enters/exits setting mode and cycles through parameters.
• Opwaartse Pyltjie-knoppie (▲): Increases parameter values.
• Down Arrow Button (▼): Decreases parameter values.

5.2. Aanpassing van parameters

To adjust a parameter:

1. Druk die STEL button to enter the setting mode. The first parameter will flash.
2. Druk STEL repeatedly to cycle through the available parameters (e.g., Over-voltage protection threshold, Under-voltage protection threshold, Over-current protection threshold, recovery delays, etc.).
3. When the desired parameter is flashing, use the ▲ (Op) en ▼ (Down) buttons to adjust its value.
4. After setting the value, wait a few seconds for the device to automatically save the setting and exit the setting mode, or press STEL again to move to the next parameter.

5.3. Parameter Ranges and Default Values (for 220V/80A model)

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.

5.4. Fabrieksterugstelling

To restore the device to its factory default settings, press and hold the ▼ (Down) button for more than 12 seconds. The display will indicate a reset.

5.5. Error Inquiry

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. Onderhoud

• Regularly inspect the device for any signs of physical damage or loose connections.
• Hou die toestel skoon en stofvry. Gebruik 'n droë, sagte lap vir skoonmaak.
• Moenie skuur skoonmaakmiddels of oplosmiddels gebruik nie.
• Verseker behoorlike ventilasie rondom die toestel om oorverhitting te voorkom.
