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

1. Giriş

The SINOTIMER STVP series automatic over-voltage ve alt hacimtage 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-voltage, cilt altıtage, 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-voltage, cilt altıtage, 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. Güvenlik Bilgileri

• Kurulum ve bakım sadece kalifiye elektrikçiler tarafından yapılmalıdır.
• Herhangi bir montaj veya kablolama işlemine başlamadan önce güç kaynağının bağlantısının kesildiğinden emin olun.
• 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.
• Gücü vermeden önce tüm kablo bağlantılarının sağlam ve doğru olduğundan emin olun.
• Do not operate the device in wet or hazardous environments.

5. Kurulum

5.1 Fiziksel Boyutlar

5.2 Montaj

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

5.3 Kablolama Şeması

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. Kurulum ve Yapılandırma

Ayar moduna girmek için, tuşuna basın ve basılı tutun. AYARLAMAK button for 3 seconds. Then, continuously press AYARLAMAK to cycle through the parameters. Use the ▲ Ve ▼ buttons to adjust the values. When "ENd" appears, press AYARLAMAK again to save the data and exit the setting mode.

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

6.1 Parameter Settings Table

6.2 Fabrika Ayarlarına Sıfırlama

To reset the device to factory settings, press and hold the ▲ Ve ▼ düğmelerine aynı anda 3 saniye boyunca basın.

7. Operasyon

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).

Aşırı ses durumundatage, cilt altıtage, 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. Sorun Giderme

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 overvoltage olaylar.
• "<U" for undervoltage olaylar.

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. Bakım

• Cihazınızı temiz tutun, toz ve nemden uzak tutun.
• Kablo bağlantılarının sıkılığını ve aşınma veya hasar belirtilerini düzenli olarak kontrol edin.
• Do not attempt to repair the device yourself. Refer to qualified personnel for service.
