What to do if the measured value jumps sporadically on Endress+Hauser Prosonic M FMU41?
If you observe the measured value jumping sporadically to higher levels with an uneven surface, you can: 1. Perform interference echo suppression. 2. Set the process conditions to 'calm surface' or 'add. agitator'. 3. Increase output damping. 4. If necessary, choose a different installation position or a larger sensor.
What to do if there is no change in measured value on filling/emptying with Endress+Hauser Measuring Instruments?
If you notice no change in the measured value during filling or emptying: 1. Perform interference echo suppression. 2. Clean the sensor if needed. 3. If necessary, select a better installation position. 4. If wide interference echoes are present, set the function "detection window" (0A7) to "off".
What to do if measured value is incorrect but measured distance is correct on Endress+Hauser Measuring Instruments?
If the measured value is incorrect, but the measured distance is correct: 1. Check the empty calibration and full calibration. 2. Check linearisation – level/ullage – max. scale – diameter vessel – linearisation table.
How to fix E 641 (echo loss) error on Endress+Hauser Prosonic M FMU41 Measuring Instruments?
To address an E 641 (echo loss) error: 1. Check application parameters. 2. If needed, choose a different installation position or a larger sensor. 3. Align the sensor parallel to the product surface, especially for bulk solids applications.
How to resolve 'no usable echo' on Endress+Hauser Measuring Instruments?
To solve the 'no usable echo' issue, check the basic calibration.
What to do if a download error occurs on Endress+Hauser Prosonic M FMU41 Measuring Instruments?
If you encounter a download error, check the connection and restart the download.
What to do if electronics defect is displayed on Endress+Hauser Prosonic M FMU41?
If an electronics defect is indicated, reset the device. Check the system for EMC and improve it if necessary. If the alarm persists after the reset, replace the electronics.
