This image illustrates the meter's capabilities, including its function as a three-phase multi-function network analyzer, 100A direct load, compatibility with 3P4W/3P3W/1P2W systems, 4-module width, measurement of various parameters (kWh, kVArh, W, Var, VA, PF, Hz, dmd, V, A, THD), bi-directional measurement for kW and kWh, RS485 Modbus RTU, and two pulsed outputs.

3. אַפּערייטינג ינסטרוקטיאָנס

The SDM630Modbus-V3 features a clear, illuminated display and simple direct operation for viewing various measurement parameters.

3.1 אַרויסווייַזונג און נאַוויגאַציע

The LCD display shows real-time energy consumption and other measured values. Use the navigation buttons (typically 'M' for Menu, 'P' for Page, and arrow keys) to cycle through different display screens and access settings.

3.2 Measurement Options

The meter provides a wide range of measurement data, including:

• Total Active Energy (kWh)
• Total Reactive Energy (kVArh)
• אַקטיוו מאַכט (kW)
• Reactive Power (kVArh)
• Apparent Power (kVA)
• מאַכט פאַקטאָר
• VoltagE (V)
• איצטיקע (א)
• אָפטקייַט (הז)

Active power (kWh) and reactive power (kVArh) are calculated on a net basis, displaying both total counter readings and separate import/export values.

3.3 קאָמוניקאַציע ינטערפייסיז

The meter is equipped with:

• RS485 Modbus-RTU Interface: For remote reading and integration into energy management systems. Supports communication up to 19.2bps.
• 2 Pulse Outputs (S0): For import and/or export, useful for connecting to external data loggers or control systems. P1 is fixed at 400 imp/kWh, while P2 is adjustable.

4. וישאַלט

The Eastron SDM630Modbus-V3 is designed for long-term, reliable operation with minimal maintenance. Regular inspection of connections and the meter's physical condition is recommended.

• רייניקונג: Use a soft, dry cloth to clean the exterior of the meter. Do not use abrasive cleaners or solvents.
• פֿאַרבינדונגען: Periodically check all wiring connections to ensure they remain tight and free from corrosion.
• סילינג: The meter includes a sealing opening for security after installation, protecting against tampering. Ensure this seal remains intact if required for billing or regulatory purposes.

No user-serviceable parts are inside the meter. Refer all internal servicing to qualified personnel.

5. טראָובלעשאָאָטינג

If you encounter issues with your Eastron SDM630Modbus-V3 meter, consider the following common problems and solutions:

• קיין אַרויסווייַז/מאַכט:
  • Check all power connections to ensure they are secure and correctly wired.
  • באַשטעטיקן אַז די אַרייַנשרייַב וואָלtage is within the specified range (100~280V AC L-N, 100~480V AC L-L).
• פאַלש רידינגז:
  • Confirm that the wiring configuration (1-phase, 3-phase 3-wire, 3-phase 4-wire) matches your electrical system.
  • Ensure current transformers (CTs), if used with a different model, are correctly installed and ratio is configured. (Note: This model is direct measuring up to 80A).
  • Check for any external interference or magnetic fields near the meter.
• Communication Issues (RS485):
  • Verify the RS485 wiring polarity (A/B).
  • Check Modbus address and baud rate settings on both the meter and the master device.
  • Ensure proper termination resistors are used on the Modbus network if necessary.
• Pulse Output Not Working:
  • Confirm the pulse output settings (P1 fixed, P2 adjustable) are correct.
  • Check the connection to the receiving device.

If problems persist after attempting these solutions, please contact Eastron technical support or your local distributor for assistance.
