6. Орнотуу жана орнотуу

Туура орнотуу үчүн бул кадамдарды кылдаттык менен аткарыңыз:

6.1 Wiring Diagram (KWS-AC301L-100A Exampле)

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.

• Кубат киргизүү: Connect the AC 50-300V power supply to terminals L and N (typically labeled 3 and 4 on the meter).
• Туташуу жүктөө: 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).

• Температура сенсору: Connect the external temperature sensor to the dedicated interface.
• 485 Интерфейс: 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).

7. Операция

The meter features a clear digital display and intuitive buttons for navigation and settings.

7.1 Дисплейview

Figure 7.1: Top display shows KWS-AC300 with Voltage, Current, Power, Timing, and Kwh. Bottom display shows KWS-AC301 with Voltage, Current, Power, Timing, Kwh, Power Factor, and Frequency.

The display shows various parameters simultaneously. The KWS-AC300 typically displays Voltage, Current, Power, Timing, and Kwh. The KWS-AC301 models additionally display Frequency and Power Factor.

7.2 Баскыч функциялары

The meters typically feature one or more buttons for interaction:

• KWS-AC300: Features a "MENU" button. Pressing this button allows cycling through display modes or accessing settings.
• KWS-AC301: Features three buttons: Up (Δ), Middle (M), and Down (∇).

Figure 7.2: KWS-AC301 button interaction. Pressing the 'M' button for 3 seconds allows entry into setting or alarm value adjustment modes.

• "M" Button (KWS-AC301):
  • Кыска басуу: Cycles through different display parameters (e.g., Voltage, Current, Power, Kwh, Timing, Temperature).
  • Узак басуу (3 секунд): Enters the setting mode or alarm value adjustment mode. Use the Up (Δ) and Down (∇) buttons to navigate and adjust values.
• 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. Техникалык тейлөө

• Keep the meter clean and free from dust. Use a soft, dry cloth for cleaning.
• Аппаратты экстремалдык температурага, тике күн нуруна же коррозиялык чөйрөлөргө тийгизүүдөн сактаңыз.
• 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. Кыйынчылыктарды

• Дисплей жок:
  • Check if the power supply (AC 50-300V) is connected correctly and active.
  • Киргизүү көлөмүн камсыз кылыңызtage белгиленген диапазондо.
• 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.
  • Check if the load is properly connected.
• 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.
