2. Bezpečnostní opatření
WARNING: Electrical shock hazard. Installation and maintenance should only be performed by qualified personnel. Disconnect power before installation or servicing.
- Ensure the main power supply is disconnected before attempting any installation or wiring.
- Verify that the protector's current rating matches or exceeds the expected load.
- The neutral line (N) of the protector is directly connected and does not have a disconnection function. Ensure proper wiring according to local electrical codes.
- Nepoužívejte zařízení, pokud se jeví poškozené.
3. Nastavení a instalace
3.1 Rozměry produktu
Before installation, verify the physical dimensions of the protector to ensure it fits within your electrical panel or enclosure.
Obrázek 3.1: Přední a boční view of the SINOTIMER Adjustable Voltage Protector with key dimensions indicated. The device measures 85mm in height, 35mm in width, and 65mm in depth (including the DIN rail clip), designed for compact installation.
3.2 Montáž
The SINOTIMER SVP-916 is designed for surface mounting, typically on a DIN rail within an electrical distribution box. Ensure a secure and stable mounting location.
3.3 Zapojení kabeláže
Follow the wiring diagram carefully. Incorrect wiring can lead to device malfunction or electrical hazards. The protector has clearly marked "IN" (Input) and "OUT" (Output) terminals for Line (L) and Neutral (N).
Obrázek 3.2: Wiring diagram illustrating the connection of the SINOTIMER Adjustable Voltage Protector (SVP-916) within an electrical circuit. It shows the protector connected between a power switch and an air circuit breaker, with clear indications for Line (L) and Neutral (N) inputs and outputs.
- Connect the incoming Line (L) and Neutral (N) wires from your power source to the "IN" terminals of the protector.
- Connect the outgoing Line (L) and Neutral (N) wires from the "OUT" terminals of the protector to your load (e.g., distribution panel, circuit breaker).
- Ujistěte se, že všechna připojení jsou pevná a bezpečná, abyste zabránili uvolnění kontaktů a přehřátí.
3.4 Počáteční zapnutí
After wiring, restore power to the circuit. The protector's LED displays should illuminate, showing the current voltage and current readings. The device will perform a self-check and then enter normal operating mode.
4. Provoz
4.1 LED displeje
The SVP-916 features two LED displays for real-time monitoring:
Obrázek 4.1: The SINOTIMER Adjustable Voltage Protector displaying voltage (red LED) and current (green LED) readings. The control buttons (SET, Up, Down) are visible below the displays.
- Upper (Red) Display: Zobrazuje naměřený objemtage (V).
- Lower (Green) Display: Shows the measured current (A).
- Kontrolky: Small LEDs indicate Overvoltage (OV: fast blink), Undervoltage (UV: slow blink), and Overcurrent (OC: fast blink).
4.2 nastavitelná nastavení
The protector allows adjustment of various parameters to customize protection levels. Use the SOUBOR, ▲ (Up), and ▼ (Down) buttons to navigate and modify settings.
- Přepětítage Protection Value (OV): Sets the maximum allowable voltage.
- Podpětítage Protection Value (UV): Sets the minimum allowable voltage.
- Overcurrent Protection Value (OC): Sets the maximum allowable current.
- Fault Recovery Delay Time (t-on): Sets the delay before the device automatically reconnects after a fault clears.
- Podpětítage Breaking Time (t-off): Sets the delay before the device trips on undervoltage. Note: If this time is greater than 0.3 seconds, the protector may not open immediately after a power failure.
4.3 Setting Adjustment Procedure
- Stiskněte a podržte SOUBOR button for a few seconds to enter the setting mode.
- Použijte SOUBOR button to cycle through the different parameters (OV, UV, OC, t-on, t-off).
- Použijte ▲ (Nahoru a ▼ (Down) buttons to adjust the value of the selected parameter.
- Once all desired settings are configured, wait for a few seconds without pressing any buttons. The device will automatically save the settings and exit the setting mode.
5. Údržba
The SINOTIMER Voltage Protector is designed for long-term, reliable operation with minimal maintenance. However, periodic checks can help ensure optimal performance.
- Čištění: Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Kontrola připojení: Pravidelně kontrolujte elektrické spoje, abyste se ujistili, že jsou pevné a bez koroze.
- Podmínky prostředí: Abyste předešli poškození, zajistěte, aby provozní prostředí zůstalo v rámci specifikovaného rozsahu teploty a vlhkosti.
- Test funkčnosti: If possible and safe to do so, periodically test the protection functions by simulating an over-voltage nebo pod-objtage condition (e.g., using a variable power supply, if available and safe).
6. Řešení problémů
This section addresses common issues you might encounter with the SINOTIMER Voltage Chránič.
| Problém | Možná příčina | Řešení |
|---|---|---|
| No display/No power output. | Žádné vstupní napájení; nesprávné zapojení; vnitřní chyba. | Verify input power supply. Check wiring connections (L and N). If power is present and wiring is correct, the device may be faulty. |
| Zařízení se často vypíná. | svtage/current fluctuations exceeding set limits; incorrect settings; overloaded circuit. | Zkontrolujte skutečný objemtage/current readings. Adjust OV/UV/OC settings if necessary, ensuring they are appropriate for your system. Reduce load if circuit is overloaded. |
| Does not automatically reconnect. | Fault condition still present; t-on delay set too long; internal fault. | Ensure the fault condition (over/under voltage/current) has cleared. Check the t-on (recovery delay) setting. If the fault has cleared and delay is appropriate, device may require manual reset (power cycle) or be faulty. |
| Nepřesný svtage/aktuální hodnoty. | Volné spoje; porucha zařízení. | Check all wiring connections for tightness. Compare readings with a calibrated multimeter. If readings are consistently off, the device may be faulty. |
| Podpětítage trip delay issue. | t-off setting is too high (greater than 0.3 seconds). | Adjust the t-off setting to a value less than or equal to 0.3 seconds if immediate disconnection upon undervoltage je žádoucí. |
