The device features a digital display for voltage and current, indicator lights for protection status, and control buttons for settings adjustment.
ຮູບທີ 1: ດ້ານໜ້າ 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 Ampການຈັດອັນດັບ.
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. ການຕິດຕັ້ງ
The TOVPD1-80-EC device is designed for DIN rail mounting (35mm). Follow these steps for proper installation:
- ການຕັດການເຊື່ອມຕໍ່ໄຟຟ້າ: Before starting, ensure the main power supply to the circuit is completely disconnected to prevent electrical shock.
- ການຕິດຕັ້ງ: Snap the device onto a standard 35mm DIN rail in your electrical panel.
- ສາຍໄຟ:
- 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.
- ໃຫ້ແນ່ໃຈວ່າການເຊື່ອມຕໍ່ທັງຫມົດແຫນ້ນແຫນ້ນແລະປອດໄພ.

5.1. ການທໍາງານຂອງປຸ່ມ
- ປຸ່ມເປີດປິດ: Turns the device ON/OFF (if applicable, or for display cycling).
- ປຸ່ມ SET: Enters/exits setting mode and cycles through parameters.
- ປຸ່ມລູກສອນຂຶ້ນ (▲): Increases parameter values.
- ປຸ່ມລູກສອນລົງ (▼): Decreases parameter values.
5.2. ການປັບຕົວກໍານົດການ
To adjust a parameter:
- ກົດ SET button to enter the setting mode. The first parameter will flash.
- ກົດ SET 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 ▲ (ຂຶ້ນ) ແລະ ▼ (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 SET again to move to the next parameter.
