- Corrent (A)
- Demand (dmd)
- I més.
Specific measurement modes and their display can be configured using the provided software.
5. Manteniment
The SDM630Modbus V3 is designed for reliable operation with minimal maintenance. However, periodic checks are recommended:
- Neteja: Mantingueu el dispositiu net i lliure de pols. Feu servir un drap suau i sec per netejar-lo. No utilitzeu productes de neteja abrasius ni dissolvents.
- Connexions: Periodically inspect all wiring connections to ensure they remain tight and secure. Loose connections can lead to inaccurate readings or device malfunction.
- Medi ambient: Assegureu-vos que l'entorn de funcionament es mantingui dins dels rangs de temperatura i humitat especificats per evitar danys.
6. Solució De Problemes
If you encounter issues with your SDM630Modbus V3, consider the following troubleshooting steps:
- Sense pantalla/alimentació:
- Check the main power supply to the meter.
- Verify all power connections are correctly wired and secure.
- Lectures inexactes:
- Ensure the wiring configuration matches your electrical system (1P2W, 3P3W, 3P4W).
- Check for loose or incorrect wiring connections.
- Verify that the meter's settings (e.g., CT ratio if applicable, though this model is direct connect up to 100A) are correctly configured.
- Communication Issues (RS485 Modbus):
- Check RS485 A and B connections for correct polarity and secure fit.
- Verify the Modbus address, baud rate, parity, and stop bits settings on both the meter and the master device.
- Ensure the communication cable length does not exceed the maximum recommended distance (1000m).
If problems persist, consult the official datasheet or contact Eastron technical support.
