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

1. Įvadas

The SINOTIMER STVP series automatic over-voltage ir pagal ttage 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, pagal ttage, 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, pagal ttage, 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. Saugos informacija

• Montavimą ir techninę priežiūrą turėtų atlikti tik kvalifikuoti elektrikai.
• Prieš bet kokius montavimo ar laidų darbus įsitikinkite, kad maitinimo šaltinis yra atjungtas.
• 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.
• Prieš įjungdami maitinimą, patikrinkite, ar visos laidų jungtys yra tvirtos ir teisingos.
• Do not operate the device in wet or hazardous environments.

5. Montavimas

5.1 Fiziniai matmenys

5.2 Montavimas

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

5.3 Sujungimo schema

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. Sąranka ir konfigūracija

Norėdami įjungti nustatymo režimą, paspauskite ir palaikykite NUSTATYTI button for 3 seconds. Then, continuously press NUSTATYTI to cycle through the parameters. Use the ▲ ir ▼ buttons to adjust the values. When "ENd" appears, press NUSTATYTI again to save the data and exit the setting mode.

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

6.1 Parameter Settings Table

6.2 Gamyklinių parametrų atkūrimas

To reset the device to factory settings, press and hold the ▲ ir ▼ mygtukus vienu metu 3 sekundes.

7. Operacija

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).

Esant per dideliam tūriuitage, pagal ttage, 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. Problemų sprendimas

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 renginiai.
• "<U" for undervoltage renginiai.

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. Priežiūra

• Laikykite prietaisą švarų, be dulkių ir drėgmės.
• 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.
