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.

  • Page 99: Appendix C: Maintenance

    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 100: 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.

    Near Range 2.2.1.12. Near Range programs SITRANS LR260 to ignore the zone in front of the antenna. The default blanking distance is 50 mm (1.97") from end of horn antenna. Near Range allows you to increase the blanking value from its factory default. But 2.2.5.2.

    20 mA 4 mA When SITRANS LR260 is put into P P ROGRAM 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.
