What does it mean if sensor is nearing its lifetime limit according to REMINDER 2 on Siemens SITRANS LR560?
If the sensor is nearing its lifetime limit according to the value set in REMINDER 2 (DEMANDED) on your Siemens Transmitter, replacement is recommended.
What to do if calibration interval has expired on Siemens SITRANS LR560?
If the calibration interval as defined in REMINDER 2 (DEMANDED) has expired on your Siemens Transmitter, perform calibration.
What to do if Siemens Transmitter nearing lifetime limit Reminder 1?
If your Siemens Transmitter is nearing its lifetime limit according to the value set in Reminder 1, replacement is recommended.
What does it mean when Siemens SITRANS LR560 Transmitter sensor is nearing its lifetime limit according to Maintenance Demanded Limit?
Replacement of the Siemens Transmitter sensor is recommended as it is nearing its lifetime limit according to the value set in Maintenance Demanded Limit.
How to fix Siemens Transmitter AIFB values being the same?
If the INPUT SCALING (2.5.4) (Page 137) upper and lower values for AIFB1 on your Siemens Transmitter are the same, check the configuration for AIFB1 and ensure that the Upper Value and Lower Value (Input Scaling) are not identical.
How to fix invalid user configuration on Siemens SITRANS LR560 Transmitter?
If the user configuration is invalid on your Siemens Transmitter because parameters like Low Calibration Point, High Calibration Point, Volume breakpoints, or Auto False-Echo Suppression are set to invalid values, you should: * Reconfigure the unit. * Ensure that the difference between the High Calibration Point and Low Calibration Point is not less than or equal to zero. Perform a Master Reset if needed.
What does it mean if Siemens SITRANS LR560 display shows level or target is out of range?
If the display shows that the level or target is out of range on your Siemens Transmitter: * Check the specifications. * Check LOW CALIBRATION POINT (2.3.5.1.). * Increase CONFIDENCE (2.4.7.1.).
What to do if the controller value is not equal to the displayed value on my Siemens SITRANS LR560 Transmitter?
If the controller value isn't matching the displayed value, first, make sure you're checking the correct location in the controller. Then, ensure that scaling is only programmed into the LR560, not the controller itself. Finally, verify that the network connection between the controller and the LR560 is working correctly.
What to do if Siemens SITRANS LR560 reading does not change?
If the reading on your Siemens Transmitter does not change even when the level does, the device might be processing the wrong echo, such as from a vessel wall or structural member. Try re-locating the device, checking the nozzle for internal burrs or welds, rotating the device 90°, or using AUTO ECHO SUPPRESSION (2.4.8.1.) (Page 132) if necessary.
How to fix a Siemens SITRANS LR560 Transmitter measurement that is consistently off?
If the measurement from your Siemens Transmitter is consistently off by a constant amount, the issue might be with the calibration settings. Try these solutions: * Check the distance from the sensor reference point to LOW CALIBRATION POINT (2.3.5.1.). * Check the SENSOR OFFSET (2.3.5.3.).
