    FAQs for SITRANS LR260, or contact your local Siemens Milltronics representative. Specifically: If you try to set a SITRANS LR260 parameter via remote communications, but the parameter remains unchanged: • Some parameters can only be changed when the device is not scanning. Try putting the device in PROGRAM mode using the operating mode function.

    Appendix C: Maintenance SITRANS LR260 requires no maintenance or cleaning under normal operating conditions. Under severe operating conditions, the horn antenna may require periodic cleaning. If cleaning becomes necessary: • Note the antenna material and the process medium, and select a cleaning solution that will not react adversely with either.

  • Page 102: Appendix D: Technical Reference

    Appendix D: Technical Reference Principles of Operation SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of solids . Radar level measurement uses the time of flight principle to determine distance to a material surface. The device transmits a signal and waits for the return echo.

    20 mA 4 mA When SITRANS LR260 is put into PROGRAM mode it stops responding to the process. It stores the most recent measurement, and holds the associated readings and mA signal output. The instrument reverts to the parameter last addressed during the previous program session.

  • Page 106: Damping

    The reading and mA output default to the last measurement taken. The reading and associated outputs migrate to the current process level at a rate controlled by the response rate (2.2.7.1). If SITRANS LR260 is left in PROGRAM mode for 10 minutes without input, it automatically reverts to Measurement mode. Damping A damping filter smooths out the response to a sudden change in level.
