Why CDI communication does not work with Endress+Hauser Micropilot FMR51 Radar?
If CDI communication is not working with your Endress+Hauser Radar, it could be due to a wrong setting of the COM port on the computer. Check the setting of the COM port on the computer and change it if necessary.
What to do if Endress+Hauser Micropilot FMR51 Radar device does not respond?
If the Endress+Hauser Radar device does not respond, ensure that the supply voltage matches the value indicated on the nameplate by connecting the correct voltage. Also, check and correct the polarity if it's wrong. Finally, ensure proper electrical contact between the cables and terminals.
Why does Endress+Hauser Micropilot FMR51 display a level when the tank is empty?
If the Endress+Hauser Radar displays a level when the tank is empty, it's likely due to an interference echo. Perform a mapping over the entire measuring range when the tank is empty by using the Confirm distance parameter.
Why is the measured value incorrect on my Endress+Hauser Radar?
If the measured value on your Endress+Hauser Radar is incorrect, check and adjust the Empty calibration parameter and the Full calibration parameter. If necessary, check and adjust linearization. For measurements in bypasses or stilling wells, select the correct Tank type (Bypass / pipe) and enter the correct diameter in the Tube diameter parameter. You may also need to enter the correct value in the Level correction parameter.
How to troubleshoot HART communication on Endress+Hauser Micropilot FMR51 Radar?
If the HART communication on your Endress+Hauser Radar does not function, ensure the communication resistor is correctly installed. Connect the Commubox correctly and set the selection switch of the Commubox to the HART position.
Why does the measured value jump sporadically on Endress+Hauser Micropilot FMR51?
If the surface is not calm and the measured value jumps sporadically to a higher level on your Endress+Hauser Radar, the signal is weakened by the rough surface. Perform tank mapping and select the tank type as 'Process vessel with agitator'. Increase the integration time and optimize the antenna orientation. Selecting a better mounting position or a larger antenna may also help.
