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

1. Ievads

The SINOTIMER STVP series automatic over-voltage un zem-sējtage 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, zem stage, 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, zem stage, 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. Drošības informācija

• Uzstādīšanu un apkopi drīkst veikt tikai kvalificēti elektriķi.
• Pirms jebkādu uzstādīšanas vai elektroinstalācijas darbu pārliecinieties, vai strāvas padeve ir atvienota.
• 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.
• Pirms strāvas pieslēgšanas pārliecinieties, vai visi vadu savienojumi ir droši un pareizi.
• Do not operate the device in wet or hazardous environments.

5. Uzstādīšana

5.1. Fiziskie izmēri

5.2 Montāža

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

5.3 Elektroinstalācijas shēma

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. Iestatīšana un konfigurēšana

Lai pārietu uz iestatīšanas režīmu, nospiediet un turiet IESTATĪT button for 3 seconds. Then, continuously press IESTATĪT to cycle through the parameters. Use the ▲ un ▼ buttons to adjust the values. When "ENd" appears, press IESTATĪT again to save the data and exit the setting mode.

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

6.1 Parameter Settings Table

6.2 Rūpnīcas atiestatīšana

To reset the device to factory settings, press and hold the ▲ un ▼ pogas vienlaicīgi 3 sekundes.

7. Darbība

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).

Pārsnieguma gadījumātage, zem stage, 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. Traucējummeklēšana

8.1 Kļūmes izmeklēšana

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 notikumi.
• "<U" for undervoltage notikumi.

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. Apkope

• Turiet ierīci tīru un bez putekļiem un mitruma.
• 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.
