User Manual: Three-Phase Adjustable Over/Under Voltage Пратэктар

1. Уводзіны

The SINOTIMER STVP series automatic over-voltagе і пад-вtage protector is designed for three-phase 3*127V/220VAC power systems with a rated working current of 80A. This device provides essential protection for electrical equipment by instantaneously cutting off the power supply when over-voltagе, пад-абtage, or over-current conditions are detected. Once the circuit voltage returns to normal, the protector automatically restores power, ensuring continuous operation and safeguarding your appliances from damage.

This protector integrates multiple protection functions including over-voltagе, пад-абtage, over-current, three-phase current (voltage) imbalance, phase sequence (reverse phase), zero-break, and phase-break protection. It also features voltmeter and ammeter functions, and the ability to restore factory settings. The device offers comprehensive features, stable performance, and ease of operation.

4. Інфармацыя па бяспецы

• Ўстаноўку і тэхнічнае абслугоўванне павінны выконваць толькі кваліфікаваныя электрыкі.
• Перад любымі мантажнымі або электрамантажнымі работамі пераканайцеся, што электрасілкаванне адключана.
• The device does not provide overload or short-circuit protection. It must be used in conjunction with appropriate external circuit breakers (e.g., C45, C65 mini circuit breakers) for comprehensive protection.
• Перад падачай харчавання пераканайцеся, што ўсе злучэнні правадоў надзейныя і правільныя.
• Do not operate the device in wet or hazardous environments.

5. Ўстаноўка

5.1 Фізічныя памеры

5.2 Мантаж

The protector is designed for 35mm DIN rail installation. Snap the device onto the DIN rail securely.

5.3 Электрычная схема

Connect the input and output terminals as shown in the diagram below. Ensure correct phase (L1, L2, L3) and neutral (N) connections. The input terminals are located at the top, and output terminals at the bottom.

6. Налада і канфігурацыя

Каб увайсці ў рэжым налад, націсніце і ўтрымлівайце НАБОР button for 3 seconds. Then, continuously press НАБОР to cycle through the parameters. Use the ▲ і ▼ buttons to adjust the values. When "ENd" appears, press НАБОР again to save the data and exit the setting mode.

If no operation is performed within 10 seconds after pressing НАБОР, the device will automatically exit the setting mode, and any unsaved changes will be lost.

6.1 Parameter Settings Table

6.2 Скід да заводскіх налад

To reset the device to factory settings, press and hold the ▲ і ▼ кнопкі адначасова на працягу 3 секунд.

7. Аперацыя

Once installed and configured, the device will continuously monitor the three-phase power supply. The LCD screen will automatically rotate to display the real-time voltage and current for each phase (L1, L2, L3).

У выпадку завышэння аб'ёмуtagе, пад-абtage, or over-current event, the protector will automatically trip and cut off the power supply to protect connected equipment. After the fault condition clears and the recovery delay time has passed, the device will automatically restore power.

8. Выпраўленне непаладак

8.1 Fault Inquiry

If a fault occurs, the device will display an error code (E0). You can press the ▲ button to query the last 5 fault records (E1-E5). The display will indicate:

• ">U" for overvoltagе падзеі.
• "<U" for undervoltagе падзеі.

8.2 Phase Sequence Error

If the LCD displays "ABC" character, it indicates a phase sequence error. To correct this, arbitrarily reverse any two of the three phase lines (L1, L2, L3) at the input.

9. Тэхнічнае абслугоўванне

• Трымайце прыладу ў чысціні і без пылу і вільгаці.
• Regularly check wiring connections for tightness and signs of wear or damage.
• Do not attempt to repair the device yourself. Refer to qualified personnel for service.
