How to fix wrong slope of level on Endress+Hauser Micropilot FMR51?
If the slope of the level is wrong in the entire measuring range on your Endress+Hauser Radar, set the Tank type parameter correctly.
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.
What does error message F941 mean on Endress+Hauser Micropilot FMR51 Radar?
If the Endress+Hauser Radar shows an error message F941 or S941 "Echo lost", it indicates that the level echo is too weak or suppressed. Check the Medium group parameter and select a more detailed setting in the Medium property parameter if necessary. Optimize the alignment of the antenna and consider a better installation position or a larger antenna. If the echo is suppressed, delete the mapping and record it again.
Why does measured value jump downwards on Endress+Hauser Micropilot FMR51 Radar?
If the measured value jumps downwards during filling or emptying with the Endress+Hauser Radar, multiple echoes may be the cause. Check the Tank type parameter. Avoid a central installation position if possible and consider using a stilling well.
What does 'Communication error' mean on Endress+Hauser Radar display?
If the Endress+Hauser Radar shows "Communication error" on the display, check the grounding of the device to rule out electromagnetic interference. If the problem persists, the display cable or plug might be broken, consider exchanging the display.
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.
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.
