Appendix B: Troubleshooting
1.
Check the following:
•
There is power at the instrument.
•
The LCD shows the relevant data you are expecting.
•
Check whether any fault codes are being displayed (see
Diagnostics (General Fault Codes)
•
The device can be programmed using the hand-held programmer.
2.
Verify that the wiring connections are correct.
3.
Check the PROFIBUS address and make sure all devices are at unique PROFIBUS
addresses.
4.
If the device cannot be programmed via the hand-held programmer, make sure Write
Locking (6.1.) on page 90 is disabled.
5.
If you try to set a SITRANS LR260 parameter via remote communications, but the
parameter remains unchanged, check the following parameters:
•
Remote Lockout (5.2.) on page 90 should be disabled
•
Write Locking (6.1.) on page 90 should be disabled
•
Resetting the PROFIBUS address to 126: on page 122 on how to disable an
address lock
6.
If you continue to experience problems, go to our website at:
www.siemens.com/processautomation, and check the FAQs for SITRANS LR260, or
contact your Siemens representative.
7.
If the PLC value equals the display value, but does not correspond to actual material
level, either:
•
scaling in AIFB1 is incorrect, or
•
High Calibration Point is incorrectly entered, or
•
the wrong echo is being selected.
8.
If the PLC value is not equal to the displayed value (regardless of actual material
level), either:
•
you may not be looking at the right spot in the PLC, or
•
you may have programmed scaling into the PLC, instead of leaving all scaling to
be performed in the LR260, or
•
the PLC may not be communicating with the LR260. Check the network to verify
that you are communicating.
