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 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 does it mean if my Siemens SITRANS LR560 Transmitter display shows antenna malfunction?
If the display on your Siemens Transmitter shows an antenna malfunction, it could be due to high temperature or physical damage. To address this: * Check the temperature in MAXIMUM VALUE (3.4.2.). * Relocate the device.
What to do if Siemens SITRANS LR560 display shows location or aiming issues?
If the display on your Siemens Transmitter shows location or aiming issues, it may be due to poor installation, a non-level flange, or incorrect application of Auto False Echo Suppression. Here’s how to address it: * Ensure the nozzle is vertical. * Ensure the end of the antenna protrudes from the end of the nozzle. * Review AUTO ECHO SUPPRESSION (2.4.8.1.). * Ensure the Auto False Echo Suppression Range is set correctly.
What to do if Siemens SITRANS LR560 Transmitter service interval Reminder 2 has expired?
If the service interval as defined in Reminder 2 has expired on your Siemens Transmitter, perform service.
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.
What causes Siemens SITRANS LR560 Transmitter to fail to get a measurement?
If your Siemens Transmitter is unable to get a measurement within the Fail-safe LOE Timer period, possible causes include faulty installation, antenna material buildup, foaming or other adverse process conditions, or an invalid configuration range. To resolve this: * Ensure installation details are correct. * Ensure no antenna material buildup and clean if necessary. * Adjust process conditions to minimize foam or other adverse conditions. * Correct the configuration range. If the fault persists, contact your local Siemens representative.
What to do when calibration interval as defined in Maintenance Required Limit has expired on Siemens SITRANS LR560?
Perform calibration on your Siemens Transmitter as the calibration interval defined in Maintenance Required Limit has expired.
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 PLC value equals display value but does not correspond to actual material level on Siemens Transmitter?
If the PLC value equals the display value but doesn't correspond to the actual material level on your Siemens Transmitter: * Ensure Scaling in AIFB1 is correctly entered. * Ensure the High Calibration Point is correctly entered. * View the echo profile to see if the wrong echo is being selected.
