What to do if Siemens Transmitter nearing lifetime limit Reminder 1?
- Rray49Sep 23, 2025
If your Siemens Transmitter is nearing its lifetime limit according to the value set in Reminder 1, replacement is recommended.
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 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.
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.).
How to fix Siemens SITRANS LR560 AIFB2 values being the same?
If the INPUT SCALING (2.5.4) (Page 137) upper and lower values for AIFB2 on your Siemens Transmitter are the same, check the configuration for AIFB2 and ensure that the Upper Value and Lower Value (Input Scaling) are not identical.
Why can't I change the SITRANS LR560 parameter on my Siemens Transmitter via remote communications?
If you are unable to change a SITRANS LR560 parameter via remote communications, ensure that Remote Lockout is disabled. Also, verify that Write Protection is set to the unlock value.
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 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.
What to do for Siemens SITRANS LR560 internal error?
If your Siemens Transmitter shows an internal error, reset the power. If the fault persists, contact your local Siemens representative.
What to do if calibration interval defined in REMINDER 1 has expired on Siemens Transmitter?
If the calibration interval as defined in REMINDER 1 (REQUIRED) has expired on your Siemens Transmitter, perform calibration.
