5. Vedligeholdelse

Regular maintenance ensures the longevity and accuracy of your ALT-666 Ultrasonic Digital Level Meter.

  • Rensning: Periodically clean the sensor surface to prevent accumulation of dirt, dust, or residue that could interfere with ultrasonic signal transmission. Use a soft, damp klæde; undgå slibende rengøringsmidler.
  • Inspektion: Regularly inspect the device for any signs of physical damage, loose connections, or corrosion. Ensure the protective cover is securely closed to maintain the IP65 rating.
  • Miljøforhold: Ensure the operating environment remains within the specified temperature range (-20-60°C) and that the device is not exposed to excessive pressure or extreme conditions beyond its IP65 rating.

6. Fejlfinding

If you encounter issues with your ALT-666, consider the following troubleshooting steps:

  • Ingen skærm/strøm: Check the DC24V power supply and ensure all wiring connections are secure. Verify the power source is active.
  • Upræcise læsninger:
    • Ensure the sensor surface is clean and free from obstructions.
    • Verify the installation height and dead zone settings are correct for your application.
    • Check for any physical obstructions in the measurement path.
    • Confirm the liquid surface is not excessively turbulent, which can affect ultrasonic readings.
  • No Analog Output (4-20mA): Check the wiring for the analog output. Verify the receiving control system is correctly configured to read the 4-20mA signal.
  • Interferens: While the device is designed to resist interference, ensure it is not placed too close to strong electrical noise sources. The built-in anti-thunder and anti-short circuit devices provide protection against common electrical disturbances.

If problems persist after following these steps, please contact your supplier for further assistance.
