6. Konfiguracja i instalacja
Aby przeprowadzić prawidłową instalację, należy dokładnie wykonać poniższe czynności:
6.1 Wiring Diagram (KWS-AC301L-100A Example)
The following diagram illustrates the wiring for the KWS-AC301L-100A model with a closed sensor (CT coil). Ensure all connections are made correctly before applying power.
Figure 6.1: Wiring connections for the KWS-AC301L-100A model, showing input voltage (IN-AC), load connection, and CT coil placement around the live wire.
- Pobór mocy: Connect the AC 50-300V power supply to terminals L and N (typically labeled 3 and 4 on the meter).
- Załaduj połączenie: Connect the load in series with the live wire (L). The CT coil should be placed around the live wire that feeds the load.
- CT Coil: Connect the CT coil wires to the designated CT terminals on the meter (typically labeled 1 and 2). Ensure the direction of the CT coil is correct as indicated by any arrows on the coil or meter.
- 20A Models: For 20A models without an external CT coil, the current measurement is internal. Connect the AC 50-300V power supply to the meter's input terminals, and the load directly through the meter's designated load terminals.
6.2 485 Communication and Temperature Sensor (KWS-AC301L Models)
For KWS-AC301L models, additional interfaces are available for 485 communication and an external temperature sensor.
Figure 6.2: KWS-AC301L model showing the dedicated interfaces for the temperature sensor and 485 communication (RS485 A+ and B- terminals).
- Czujnik temperatury: Connect the external temperature sensor to the dedicated interface.
- 485 Interfejs: Connect the RS485 A+ and B- terminals to your 485 communication network for data acquisition. PC software may be available for data logging and analysis (refer to product documentation or manufacturer's website for download links).

- Up (Δ) and Down (∇) Buttons (KWS-AC301): Used to navigate menus, increase or decrease values in setting modes.
7.3 Resetting Electrical Energy and Timing
To reset the cumulative electrical energy (Kwh) and timing (H) values, typically a long press on a specific button (often the "M" or "MENU" button) while in the Kwh or Timing display mode will initiate the reset process. Confirm the reset if prompted by the display.
8. Konserwacja
- Utrzymuj miernik w czystości i zapobiegaj jego zakurzeniu. Do czyszczenia używaj miękkiej, suchej ściereczki.
- Unikaj wystawiania urządzenia na działanie ekstremalnych temperatur, bezpośredniego światła słonecznego lub środowiska powodującego korozję.
- Do not attempt to open or repair the meter yourself, as this may void the warranty and pose a safety risk.
- Ensure all wiring connections remain secure over time.
9. Rozwiązywanie Problemów
- Brak wyświetlacza:
- Check if the power supply (AC 50-300V) is connected correctly and active.
- Upewnij się, że głośność wejściowatage mieści się w określonym zakresie.
- Incorrect Current/Power Reading:
- For 100A models, verify the CT coil is correctly installed around the live wire and connected to the meter.
- Ensure the CT coil direction is correct.
- Sprawdź, czy obciążenie jest prawidłowo podłączone.
- Parameters Not Resetting:
- Refer to Section 7.3 for the correct procedure to reset Kwh and Timing. Ensure the button is pressed for the required duration.
- 485 Communication Issues (KWS-AC301L):
- Verify the A+ and B- connections are correct.
- Check communication settings (baud rate, parity, stop bits) on both the meter and the connected device.
