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

1. Úvod

The SINOTIMER STVP series automatic over-voltage a pod-zvtage 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, pod-voltage, 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, pod-voltage, 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. Bezpečnostní informace

• Instalaci a údržbu by měli provádět pouze kvalifikovaní elektrikáři.
• Před jakoukoli instalací nebo elektroinstalačními pracemi se ujistěte, že je odpojeno napájení.
• 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.
• Před připojením napájení zkontrolujte, zda jsou všechna zapojení bezpečná a správná.
• Do not operate the device in wet or hazardous environments.

5. Instalace

5.1 Fyzické rozměry

5.2 Montáž

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

5.3 Schéma zapojení

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. Nastavení a konfigurace

Chcete-li vstoupit do režimu nastavení, stiskněte a podržte tlačítko SOUBOR button for 3 seconds. Then, continuously press SOUBOR to cycle through the parameters. Use the ▲ a ▼ buttons to adjust the values. When "ENd" appears, press SOUBOR again to save the data and exit the setting mode.

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

6.1 Parameter Settings Table

6.2 Obnovení továrního nastavení

To reset the device to factory settings, press and hold the ▲ a ▼ tlačítka současně po dobu 3 sekund.

7. Provoz

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).

V případě přeobjtage, pod-voltage, 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. Řešení problémů

8.1 Dotazování poruch

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 události.
• "<U" for undervoltage události.

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. Údržba

• Udržujte zařízení čisté a bez prachu a vlhkosti.
• Pravidelně kontrolujte těsnost kabelových spojů a známky opotřebení nebo poškození.
• Do not attempt to repair the device yourself. Refer to qualified personnel for service.
