User Manual: Three-Phase Adjustable Over/Under Voltagе Протецтор

1. Увод

The SINOTIMER STVP series automatic over-voltagе и под-волtage 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, под-волtage, 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, под-волtage, 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. Безбедносне информације

• Инсталацију и одржавање треба да обављају само квалификовани електричари.
• Ensure the power supply is disconnected before any installation or wiring work.
• 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.
• Проверите да ли су сви спојеви ожичења безбедни и исправни пре него што укључите напајање.
• Do not operate the device in wet or hazardous environments.

5. Инсталација

5.1 Физичке димензије

5.2 Монтажа

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

5.3 Дијаграм ожичења

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. Подешавање и конфигурација

Да бисте ушли у режим подешавања, притисните и држите СЕТ button for 3 seconds. Then, continuously press СЕТ to cycle through the parameters. Use the ▲ и ▼ buttons to adjust the values. When "ENd" appears, press СЕТ again to save the data and exit the setting mode.

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

6.1 Parameter Settings Table

6.2 Ресетовање на фабричка подешавања

To reset the device to factory settings, press and hold the ▲ и ▼ тастери истовремено 3 секунде.

7. Операција

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 случају преко-волtagе, под-волtage, 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.

КСНУМКС. Решавање проблема

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 догађаји.
• "<U" for undervoltagе догађаји.

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. Одржавање

• Држите уређај чистим и без прашине и влаге.
• Редовно проверавајте спојеве ожичења да ли постоје затегнутост и знаци хабања или оштећења.
• Do not attempt to repair the device yourself. Refer to qualified personnel for service.
