  • Page 24: Operation

    Operating SITRANS LR400 Use the arrow keys at the bottom of the hand programmer to program SITRANS LR400. 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 22 for information on navigating the menus using the arrow keys).

  • Page 25: Selecting A Parameter

    Selecting a Parameter After a successful self-test, SITRANS LR400 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 26: Changing A Parameter Value

    If you press UP when the value is at the top of the representable range, SITRANS LR400 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.

    Switch off window tracking for applications where SITRANS LR400 is unable to keep up to level changes. By using SIMATIC PDM, you can display a list of all echoes in your vessel. It provides the distance between the flange and the measuring medium’s surface, as well as the distances of fixed targets.

  • Page 95: Measuring Principle

    Appendix III Measuring Principle SITRANS LR400 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 92). A receiver registers the reflection at the surface of the measuring medium and links it with the simultaneously radiated signal.

  • Page 96

    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 92 SITRANS LR400 (7ML5421) – INSTRUCTION MANUAL 7ML19985FH06...

  • Page 97: Hart Communications For Sitrans Lr400

    SITRANS LR400 should work well with any of the different software packages available. HART Device Description (DD) The SITRANS LR400 cannot be set up using a Generic DD. To configure a HART device, the configurator must have the HART Device Description for the SITRANS LR400. 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 LR400 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 102: Bus Termination

    Configuration information is only needed periodically and is set up as acyclic data. Cyclic Data When you configure SITRANS LR400 on the PROFIBUS PA bus, there are two slots available for modules. Each of the slots has to have a module defined in it.
