Warning: • • Installation shall only be performed by qualified personnel and in accordance with local governing regulations The SITRANS LR 400 is to be used only in the manner outlined in this manual or protection provided by equipment may be impaired. Qualified personnel General Information mmmmm Qualified personnel are familiar with the installation, commissioning, and operation of this equipment.
SITRANS LR 400 The SITRANS LR 400 Radar Level Instrument is designed for level measuring of liquids and solids in storage vessels. SITRANS LR 400 operates reliably with its high microwave frequency even with poorly reflecting measuring media. The narrow antenna beam results in a sharp radiation cone, therefore SITRANS LR 400 is quite insensitive to vessel interferences.

sitranslrd3.book Page 11 Tuesday, October 9, 2001 10:09 AM Installation Note: • The SITRANS LR 400 is rated for Type 4X/NEMA 4X, Type 6/NEMA 6, IP 67. Follow all installation and operating instructions to meet the requirements of this type of protection. Use only approved, suitable sized hubs for watertight applications. Observe all maximum permissible ambient and process temperatures. Refer to Appendix III (Ambient/Operating Temperature Specification).
sitranslrd3.book Page 12 Tuesday, October 9, 2001 10:09 AM Correct Installation in Mounting Nozzle Installation mmmmm The bottom edge of the antenna must reach inside the vessel to avoid reflective interference at the wall of the nozzle. Above flange size DN 150/6 inch, the antenna may end in the nozzle unless the radiation cone (the extension of the antenna’s angle) touches the nozzle wall.

chap6.fm Page 16 Tuesday, October 9, 2001 2:26 PM Operation General information You can operate the SITRANS LR 400 with: • • • Local operating and monitoring module HART-Communicator or Profibus PA PC/Laptop and SIMATIC PDM software (recommended) Operation mmmmm Note: The device can be operated and programmed most comfortably with the SIMATIC PDM software.
chap6.fm Page 17 Tuesday, October 9, 2001 2:26 PM Since the transmission signal has changed its frequency until the reception signal arrives, the link gives a differential frequency fd, which is proportional to the distance d from the reflecting surface.
chap6.fm Page 18 Tuesday, October 9, 2001 2:26 PM Warning: The coupling module (shown below) may not be used in areas where there is an explosion hazard and may not be connected to intrinsically safe circuits. The electrical connection of the PC/Laptops and the HART-Communicator to the 4-20-mA signal cable is shown below.
chap6.fm Page 19 Tuesday, October 9, 2001 2:26 PM Operating the SITRANS LR 400 To access parameters, use the optical control elements on the operating and monitoring module (shown below).

Value numerical value, Minimum value = Length of the antenna Specification of a *dead band in the units system selected according to Parameter 4.1.5 defines a minimum distance from the flange which the measuring medium must have for the device to accept the measured values as valid. This suppresses reflective interference generated by e. g.
chap6.fm Page 36 Tuesday, October 9, 2001 2:26 PM If the display does not follow the level height continuously but in abrupt jumps, you should choose a higher filling speed. If multiple echoes are indicated during filling/emptying a vessel, select a lower filling speed. In the case of very low filling speeds (a few mm/min) switch off Parameter 4.2.3.3. If different filling/emptying speeds occur, select the higher speed. 4.2.2.

Value numerical This parameter is not displayed when a user vessel is selected in parameter 4.2.2.1. The sensor damping influences the evaluation of the measuring signal.
chap6.fm Page 38 Tuesday, October 9, 2001 2:26 PM 4.2.3.4: Window Tracking (F = on) Value on off A window follows the measured value which it is forced to track. The window size is calculated from the set filling speed. The parameter “window tracking” would be switched off for applications where the SITRANS LR 400 is unable to keep up to level changes. 4.2.3.
