4. Налаштування та встановлення

The DTS238-7 ZN/S energy meter is designed for Din Rail mounting. Ensure all power is disconnected before proceeding with installation.

4.1 Схема підключення

Refer to the diagram below for correct wiring connections. This meter supports a 3-phase, 4-wire connection.

малюнок 1: Wiring Diagram. This image illustrates the connection points for the three phases (A, B, C), neutral (N), and pulse/RS485 communication terminals. Input connections are at the top, and output connections are at the bottom. The pulse output terminals are labeled 15 (P-) and 16 (P+), while the RS485 communication terminals are labeled 17 (A) and 18 (B).

4.2 Етапи підключення

1. Mount the meter securely onto a standard Din Rail.
2. Connect the incoming three-phase lines (A, B, C) to the corresponding input terminals at the top of the meter.
3. Connect the neutral line (N) to the designated neutral input terminal.
4. Connect the outgoing three-phase lines (A, B, C) from the bottom terminals of the meter to the load.
5. Connect the neutral line (N) from the bottom terminal to the load.
6. For pulse output, connect to terminals 15 (P-) and 16 (P+).
7. For RS485 communication, connect to terminals 17 (A) and 18 (B).
8. Перед поновленням живлення двічі перевірте всі з'єднання на міцність та правильність.

5. Інструкція з експлуатації

Once properly installed and powered, the meter will display energy consumption data on its LCD screen.

5.1 Дисплей та індикатори

• РК-дисплей: Shows the accumulated energy consumption in kWh.
• Impulse Indication (PULSE LED): Flashes to indicate energy consumption. A faster flash rate signifies higher power usage.
• Lose Phase Indication (L1, L2, L3 LEDs): These LEDs illuminate to indicate the presence of each phase. If an LED is off, it suggests a loss of that specific phase.

5.2 Кнопки керування

• Кнопка SET: Використовується для входу в меню налаштувань або підтвердження вибору.
• Up (Triangle) Button: Used to navigate upwards through menu options or increase values.
• Down (Inverted Triangle) Button: Used to navigate downwards through menu options or decrease values.

Specific menu navigation and parameter settings will depend on the meter's firmware version. Refer to the on-screen prompts for detailed configuration.

6. Технічне обслуговування

The RWRAPS DTS238-7 ZN/S energy meter requires minimal maintenance. Follow these guidelines to ensure optimal performance:

• Прибирання: Periodically wipe the meter's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Перевірки підключення: Annually inspect all wiring connections to ensure they remain tight and free from corrosion.
• Умови навколишнього середовища: Ensure the meter operates within its specified temperature and humidity ranges to prevent damage.

7. Вирішення проблем

If you encounter issues with your energy meter, consider the following basic troubleshooting steps:

• Без дисплея/живлення:
  • Verify that the main power supply to the meter is active.
  • Перевірте всі з'єднання проводів на наявність ослабленого кріплення або неправильного розташування.
  • Переконайтеся, що обtage supply is within the meter's specified operating range.
• Неправильні показання:
  • Confirm that the wiring matches the diagram for your specific application (e.g., 3-phase, 4-wire).
  • Ensure the meter's rated current and voltage match your system's requirements.
• Lose Phase Indication (L1, L2, or L3 LED off):
  • Check the corresponding phase line for power supply issues or disconnections.
  • Inspect the terminal connection for that specific phase on the meter.

If problems persist after performing these checks, contact qualified personnel or the manufacturer for assistance.
