9. Maintenance
- Cleaning: Keep the module clean and free from dust. Use a soft, dry cloth for cleaning. Avoid using liquids or abrasive cleaners.
- Ventilation: Ensure the cooling fans and heatsink remain unobstructed to maintain proper airflow. Periodically check for dust buildup in the fans and clean if necessary.
- Connections: Periodically inspect all wiring connections to ensure they are secure and free from corrosion.
- Storage: When not in use for extended periods, store the module in a dry, cool environment away from direct sunlight and extreme temperatures.
10. Troubleshooting
- No Power/Display:
- Check input power connections and ensure the DC voltage is within the 12.00V-90.0V range.
- Verify the power switch on the main board is in the 'ON' position. - No Output:
- Ensure the output is enabled via the ON/OFF button on the control panel.
- Check output load connections.
- Verify that the set output voltage is lower than the input voltage (considering the 0.945 factor). - Overheating:
- Check for obstructions around the cooling fans and heatsink.
- Ensure adequate ventilation in the operating environment.
- Reduce the load or input power if the module consistently overheats. - Inaccurate Readings:
- Ensure all connections are tight and free from resistance.
- If persistent, consider recalibration if supported by firmware or contact support. - Remote Control Not Responding:
- Check the remote control's battery.
- Ensure the IR or 433M receiver module is correctly connected and within range.
