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. On both versions, the narrow antenna beam results in a sharp radiation cone, which makes the SITRANS LR 400 quite insensitive to vessel interferences.

Push the power cable and signal cable through the cable gland on the right of the unit, up to the terminal strip. Lay the cable in a bend before the cable gland so that moisture cannot enter the connection box. 4. Connect the earth conductor of the power supply to the earth terminal in the connection box.
Start Up mmmmm Start Up Self-test The device performs a self-test after power is supplied. Then, the unit is ready for programming when the multi-display appears. Note: Frequent switching off and on of the device causes aging of the electronics (see Parameter 3.1). Multi-display The multi-display shows on the LCD after a successful self-test with the output of the level in the first line and the signal-to-noise ratio in the second line (factory setting): + 1 2 .
Operation General Information You can operate the SITRANS LR 400 with: • • • Hand-held infrared programmer HART Communicator or PROFIBUS PA PC/Laptop and SIMATIC PDM software (recommended) Notes: • 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).
As the transmission signal has changed its frequency until the reception signal arrives, the linked signal gives a differential frequency fd, which is proportional to the distance d from the reflecting surface.
Operating the SITRANS LR 400 Use the arrow keys at the bottom of the hand programmer to program the 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 27 for information on navigating the menus using the arrow keys). Hand Programmer Note: The ARROW buttons shown below are required for programming this product. The additional buttons on the hand programmer do not apply to the SITRANS LR 400.
Structure of Parameters Operation is hierarchically structured: the parameters are arranged in groups and assigned a numerical menu identification (see example below). 2. Display 1 Multi-display 2.

Entering a Parameter Value The ARROW keys operate like a cursor control when entering a parameter value with the input position marked by flashing of a single character. • • • Increase or decrease a character’s value by using UP and DOWN . Press RIGHT to move the input position to the right. At the far right position, press RIGHT again: operates like an ENTER key. The device saves the changed value and closes the parameter unless the value is not within the permissible input range.
Disabling and Enabling Programming To prevent unauthorized personnel causing programming errors through the display module, set a customer code – a personal, freely selectable code number up to 9 digits. A device protected by a customer code still displays all functions and values but it requests input of the code number before allowing a parameter to be reset. Note: The customer code is activated 10 minutes after you have programmed Parameter 5.2 Customer Code.

Appendix VI PROFIBUS PA Communications for the SITRANS LR 400 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).
Power Demands The maximum number of devices that can be connected to a bus line depends on their current consumption and the respective application conditions. When operating in an area where there is no risk of explosion, the couplers/links can feed up to 400 mA into the bus. When operating in explosion risk areas, the intrinsic safety is only guaranteed when the maximum power fed into the bus does not exceed certain voltage and current values.
The 3 function blocks (Level, Volume, Mass) return 5 bytes of data each: Floating Point Status Level byte 1 byte 2 byte 3 byte 4 byte 5 Volume byte 6 byte 7 byte 8 byte 9 byte10 Mass byte 11 byte 12 byte 13 byte 14 byte 15 The 5 bytes must be read consistently, in a contiguous chunk: they cannot be read byte by byte, and cannot suffer an interrupt. If you are using an S7-300/400, you will need to use SFC14 DPRD_DAT: Read Consistent Data of a Standard PD Slave.
