Why Endress+Hauser Radar device does not respond?
If your Endress+Hauser Radar device isn't responding, it could be due to the following reasons: * The supply voltage is not connected. In this case, connect the correct voltage. * The cables do not contact the terminals properly. Ensure electrical contact between the cable and the terminal.
What to do if Endress+Hauser Micropilot FMR51 measured value is incorrect?
If the measured value of your Endress+Hauser Radar is incorrect, here are a few things you can check: * If the measured distance matches the real distance, there may be a calibration error. Check and adjust the Empty calibration parameter, Full calibration parameter and linearization if necessary. * For measurements in bypasses or stilling well, ensure the correct tank type is selected and the tube diameter parameter is correct. Select 'Bypass / pipe' for the tank type and enter the correct diameter in the Tube diameter parameter. * Enter the correct value in the Level correction parameter. * If the measured distance does not match the real distance, there may be an interference echo. Carry out tank mapping.
Why there is no change of measured value on filling / emptying with Endress+Hauser Radar?
If there's no change in the measured value during filling or emptying with your Endress+Hauser Radar, it's likely due to: * Interference echo from installations, nozzle, or build-up on the antenna. To resolve this: * Carry out tank mapping. * Clean the antenna if necessary. * Select a better mounting position if needed.
What to do if Endress+Hauser Radar measured value jumps sporadically to a higher level?
If the measured value jumps sporadically to a higher level when the surface is not calm (e.g., during filling, emptying, or when an agitator is running) with your Endress+Hauser Radar, it's likely because the signal is weakened by the rough surface, making interference echoes stronger. Here are some steps to take: * Carry out tank mapping. * Select 'Process vessel with agitator' for the Tank type. * Increase the integration time. * Optimize the antenna orientation. * Select a better mounting position and/or larger antenna if necessary.
How to fix error message F941 or S941 "Echo lost" on Endress+Hauser Micropilot FMR51 Radar?
The error message F941 or S941 "Echo lost" on your Endress+Hauser Radar indicates that the level echo is too weak or suppressed. To resolve this: * Check the Medium group parameter. If necessary, select a more detailed setting in the Medium property parameter. * Optimize the alignment of the antenna. If necessary, select a better installation position and/or larger antenna. * If the level echo is suppressed, delete the mapping and record it again.
Why Endress+Hauser Micropilot FMR51 device measures incorrectly?
If your Endress+Hauser Radar device is measuring incorrectly, it may be due to a parametrization error. Check and adjust the parameterization.
What to do if Endress+Hauser Radar displays a level when the tank is empty?
If your Endress+Hauser Radar displays a level when the tank is empty, it is likely due to an interference echo. Carry out mapping over the entire measuring range when the tank is empty.
How to fix invisible values on Endress+Hauser Micropilot FMR51 Radar display?
If the values on your Endress+Hauser Radar display are invisible, here are some things to try: * The contrast setting may be too weak or too strong. Increase contrast by pressing the appropriate buttons simultaneously or decrease contrast by pressing the appropriate buttons simultaneously. * The plug of the display cable may not be connected correctly. Connect the plug correctly. * The display may be defective. Replace the display.
Why during filling/emptying the measured value jumps downwards on Endress+Hauser Micropilot FMR51?
If, during filling or emptying, the measured value jumps downwards on your Endress+Hauser Radar, it could be caused by multiple echoes. To address this: * Check the Tank type parameter. * If possible, avoid a central installation position. * If appropriate, consider using a stilling well.
What to do if "Communication error" is indicated on the Endress+Hauser Micropilot FMR51 display?
If a "Communication error" is indicated on the display of your Endress+Hauser Radar when starting the device or connecting the display, it could be due to: * Electromagnetic interference. Check the grounding of the device. * A broken display cable or display plug. Exchange the display.
