What to do if upper and lower values for AIFB1 are the same on Siemens Transmitter?
If the upper and lower values for AIFB1 are the same in INPUT SCALING: * Check the configuration for AIFB1. * Ensure that the Upper Value and Lower Value (Input Scaling) are not the same.
What if LOW and HIGH CALIBRATION POINT are the same on Siemens SITRANS LR560?
If the LOW CALIBRATION POINT and HIGH CALIBRATION POINT parameters are the same on your Siemens Transmitter: * Check the calibration settings of the device. * Ensure the settings for the High Calibration Point and Low Calibration Point are different.
Why is the screen blank on my Siemens Transmitter?
If the screen on your Siemens Transmitter is blank: * Check the nameplate rating against the voltage supply. * Check the power wiring or source.
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.
Why can't I change parameters via remote communications on my Siemens SITRANS LR560 Transmitter?
If you cannot change parameters via remote communications on your Siemens Transmitter: * Ensure REMOTE LOCKOUT (6.1.1.) is disabled. * Ensure WRITE PROTECT (6.2.1.) is set to the unlock value.
What to do if internal temperature of Siemens SITRANS LR560 has exceeded specifications?
If the internal temperature of your Siemens Transmitter exceeds specifications, it's operating outside its temperature range. Here’s what to do: * Relocate the device and/or lower the process temperature to cool it down. * The fault code will persist until a manual reset is performed using SIMATIC PDM or the LCD interface.
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.).
Why doesn't the reading change on my Siemens Transmitter when the level changes?
If the reading on your Siemens Transmitter doesn't change even when the level does, the device might be processing the wrong echo, such as from a vessel wall or structural member. Try these solutions: * Relocate the SITRANS LR560. * Check the nozzle for internal burrs or welds. * Rotate the device 90 degrees. * Use AUTO ECHO SUPPRESSION (2.4.8.1.) if necessary.
What to do if my Siemens Transmitter fails to measure within the Fail-safe LOE Timer period?
If your Siemens Transmitter doesn't get a measurement within the Fail-safe LOE Timer period, it could be due to faulty installation, antenna material buildup, adverse process conditions, or an invalid configuration range. Here’s what you can do: * Ensure the installation details are correct. * Make sure there is no material buildup on the antenna; clean it if necessary. * Adjust process conditions to minimize foam or other adverse conditions. * Correct the configuration range.
What to do if Siemens Transmitter calibration interval Reminder 1 has expired?
If the calibration interval as defined in Reminder 1 has expired on your Siemens Transmitter, perform calibration.
