4. Konfiguracja i instalacja
The GRV8-05 relay is designed for 1-MODULE DIN rail mounting.
4.1 Montaż
- Upewnij się, że zasilanie jest odłączone.
- Snap the relay onto a standard 35mm DIN rail.
4.2 Okablowanie
Refer to the specific wiring diagram for your model (3-wire or 4-wire system). Ensure all connections are tight and correct.
4.3 Konfiguracja początkowa
The device controls its own supply voltage using True RMS measurement. Set the rated operating voltage using the knob on the front panel. The GRV8-05 allows setting 8-level rated operating voltagt.j.
5. Działanie
The GRV8-05 relay provides protection functions including overvoltage, podobjtage, phase asymmetry, phase sequence, and phase failure, with an adjustable delay time.
5.1 Elementy sterujące i wskaźniki na panelu przednim
The front panel typically features:
- Un Knob: To set the rated operating voltage.
- U> Knob: To set the overvoltage threshold (2% to 20% above Un).
- U< Knob: To set the undervoltage threshold (-20% to -2% below Un).
- Asy Knob: To set the phase asymmetry threshold (8%).
- Tt Knob: To set the delay time (0.1s to 10s).
- LED Un (Green): Indicates the status of the supply voltage.
- LED R (Red): Indicates the relay output status.
5.2 Function Diagrams
The relay operates based on the configured parameters. The following diagrams illustrate the behavior of the relay under different fault conditions:
- Phase Failure and Phase Sequence Function: The relay monitors the presence and correct sequence of all three phases. If a phase is lost or the sequence is incorrect, the relay will trip after the set delay time.
- Przepełnienietage i UndervoltagFunkcja: The relay continuously monitors the voltage levels. If the voltage exceeds the upper threshold (U>) or drops below the lower threshold (U<) for the set delay time (To/Tu), the relay will trip.
- Asymmetry Function: The relay monitors the voltage balance between phases. If the asymmetry exceeds the set threshold (Asy) for the set delay time (Ta), the relay will trip.
6. Konserwacja
The GEYA GRV8-05 Voltage Protection Relay is designed for long-term, maintenance-free operation under normal conditions. However, periodic checks are recommended:
- Kontrola wizualna: Regularly inspect the device for any signs of physical damage, discoloration, or loose connections.
- Szczelność zacisku: Ensure all wiring terminals remain tight to prevent overheating or intermittent operation.
- Warunki środowiskowe: Sprawdź, czy środowisko pracy mieści się w określonym zakresie temperatury i wilgotności.
- Czyszczenie: If necessary, gently clean the exterior of the device with a dry, soft cloth. Do not use solvents or abrasive cleaners.
7. Rozwiązywanie Problemów
If the relay is not functioning as expected, consider the following:
- No Power (LED Un Off): Check the main power supply to the relay. Ensure all phases are present and correctly connected.
- Relay Tripped (LED R Off, or flashing):
- Przepełnienietage/Podobtage: Sprawdź objętość liniitage. Adjust U> or U< settings if necessary.
- Phase Asymmetry: Sprawdź głośnośćtage balance across phases. Ensure loads are balanced. Adjust Asy setting if necessary.
- Phase Sequence/Failure: Verify the phase sequence is correct and all phases are present. Correct any wiring errors.
- Nieprawidłowy czas opóźnienia: Check the Tt knob setting.
- Działanie przerywane: Sprawdź wszystkie połączenia przewodów pod kątem poluzowania i korozji.
If the issue persists after basic troubleshooting, contact qualified technical support.

10. Wskazówki użytkownika
- Ustawienia optymalne: When setting the over/undervoltage and asymmetry thresholds, consider the typical voltage fluctuations in your electrical system to avoid nuisance tripping while ensuring adequate protection.
- Czas opóźnienia: Utilize the adjustable delay time (Tt) to prevent immediate tripping during momentary voltage dips or surges, which can be common in some industrial environments.
- Regularne kontrole: Periodically test the functionality of the relay if your application allows, to ensure it responds correctly to simulated fault conditions.
