SITRANS LR 400
The SITRANS LR 400 is to be used only in the manner outlined in this manual, otherwise
protection provided by the equipment may be impaired.
The SITRANS LR 400 is a long-range FMCW radar level instrument. A liquids version (7ML5421)
is available for use in liquids storage, performing well on low dielectric liquids or sticky
materials requiring a purging unit. A solids version (7ML5420) incorporates the Easy Aimer
design for use in solids, especially conditions of extreme dust.
The SITRANS LR 400 supports HART,1or PROFIBUS PA (optional).

Local Programming
To begin parameter changes, use the hand programmer and press LEFT once. Main
Menu is displayed in the first line of the LCD. Then program the unit beginning with the
Auto-Setup parameters.
Functions of Hand Programmer Keys
•Changes display from RUN mode to PROGRAM mode
•Operates as a CANCEL key when programming input position is at the far left
•Moves input position to the left during PROGRAM mode
•Operates as an ENTER key when input position is at the far right
•Moves input position to the right during PROGRAM mode
•Changes input variable up or down
Auto-Setup
After switching on the SITRANS LR 400, and after a successful self test, press LEFT to
access the parameters. Set the Auto-Setup parameters to make the system operational:
• language of the local user interface
• unit of length of the measured level (cm,m,mm,ft,in)
• nozzle height in the selected unit of length
• vessel height in the selected unit of length
• LRV as a distance from the bottom of the vessel
• URV as a distance from the bottom of the vessel
• damping of the measured level in seconds
• application type
• bus-address by PROFIBUS PA communication (on PROFIBUS models)

SITRANS LR 400 Communications
HART/mA Connections
PROFIBUS PA Connections
HART or PROFIBUS PA
• You will need the full manual to acquire the list of applicable parameters.
• The HART Device Descriptor (DD) may be obtained from the HART Communications
Foundation at www.hartcomm.org
• Many software packages can be used to program the instrument, but we
recommend that you use Simatic Process Device Manager (PDM) to program your
instrument on a network. This software package is designed to permit easy
configuration, monitoring and troubleshooting of HART and PROFIBUS PA devices.
• The GSD file for PROFIBUS PA can be downloaded it from our web site at
www.siemens.com/processautomation
Maintenance
The SITRANS LR 400 requires no maintenance or cleaning under normal operation conditions.
Under severe operating conditions, the antenna may require periodic cleaning using a brush or
high pressure air cleaning.
