    SITRANS LR 400 The SITRANS LR 400 is a long-range FMCW radar level instrument. A liquids version (L) is available for use in liquids storage, performing well on low dielectric liquids or sticky materials requiring a purging unit. A solids version (S) incorporates the Easy Aimer design for use in solids, especially conditions of extreme dust.

  • Page 27: Operation

    Measuring Principle The SITRANS LR 400 operates according to the FMCW (Frequency Modulated Continuous Wave) method. Its antenna sends microwaves to the surface of the measuring medium. The wave frequency is modulated continuously (see Determining the Differential Frequency on page 25).
  • Page 28 Every reflection at a surface generates a different frequency. The reception signal therefore consists of a frequency mix from which the disturbance frequencies must be filtered. These can be caused by fixed targets like struts inside the vessel. Page 25 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04...

    SITRANS LR 400 buttons Selecting a Parameter After a successful self-test, the SITRANS LR 400 displays the two-line multi-display. Press LEFT ARROW to access the parameter menus. The first line of the display tells you the current parameter menu level. The second line shows one of the parameters you can access in the current parameter group.

  • Page 31 If you press UP when the value is at the top of the representable range, SITRANS LR 400 automatically places the value at the next highest position. If 0.9 is displayed and you press UP , the value becomes 1.0. So, 9 becomes 10, 90 or 99 become 100 (depending on whether you have set the input position to the second or first 9), etc.

    PROFIBUS PA is an open industrial protocol. Full details about PROFIBUS PA can be obtained from PROFIBUS International at www.profibus.com The SITRANS LR 400 is a Class A, Profile Version 3.0, PA device. It supports Class 1 Master for Cyclic data exchange, and Class 2 for acyclic services: (See below for details).

  • Page 100: Power Demands

    Input and output information is always requested at every bus scan and is set up as cyclic data. Configuration information is only needed periodically and is set up as acyclic data. Cyclic Data When you configure the SITRANS LR 400 on the PROFIBUS PA bus, there are two slots available for modules. Note: Each of the slots has to have a module defined in it.
