  • Page 21: Operation

    Operating SITRANS LR 400 Use the arrow keys at the bottom of the hand programmer to program SITRANS LR 400. The two-line LCD displays the parameters. You can alter the setting or change to other parameters using the arrows on the hand programmer (see page 20 for information on navigating the menus using the arrow keys).

  • Page 22: Selecting A Parameter

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

  • Page 23: Changing A Parameter Value

    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.

  • Page 96: Measuring Principle

    Appendix IV Measuring Principle SITRANS LR 400 operates according to the FMCW (Frequency Modulated Continuous Wave) method. Its antenna sends microwaves to the surface of the material. The wave frequency is modulated continuously (see Determining the Differential Frequency on page 94).

  • Page 97

    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 94 SITRANS LR 400 (Solids) – INSTRUCTION MANUAL 7ML19985JC02...

  • Page 98: Hart Communications For Sitrans Lr 400

    SITRANS LR 400 should work well with any of the different software packages available. HART Device Description (DD) The SITRANS LR 400 cannot be set up with a Generic DD. To configure a HART device, the configurator must have the HART Device Description for the SITRANS LR 400. All HART DDs are collected by the HART Communication Foundation (HCF) and are placed in the HCF library.

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

  • Page 104

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