4.2 Basic Operation

  1. Power On: Once correctly wired, the device will power on and the LCD will illuminate.
  2. Monitoring Readings: The LCD will display the current liquid level or spatial distance.
  3. Configuration: Use the 'SET' button to enter the configuration menu. Navigate through options using the 'UP' and 'DOWN' arrows, and confirm selections with 'OK'. Specific parameters such as measurement units or calibration offsets can be adjusted here. Refer to the detailed programming guide for advanced settings.
  4. Analog Output: The device continuously outputs a 4-20mA signal corresponding to the measured level, which can be integrated with industrial control systems.

5. Maintenance

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

  • Cleaning: Periodically clean the sensor surface to prevent accumulation of dirt, dust, or residue that could interfere with ultrasonic signal transmission. Use a soft, damp cloth; avoid abrasive cleaners.
  • Inspection: 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.
  • Environmental Conditions: 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. Troubleshooting

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

  • No Display/Power: Check the DC24V power supply and ensure all wiring connections are secure. Verify the power source is active.
  • Inaccurate Readings:
    • 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.
  • Interference: 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.
