Safety Notes
Special attention must be paid to warnings and notices highlighted from the rest of the
text by grey boxes.
• These instructions do not claim to cover all details or variations in equipment, or to
provide for every possible contingency that may arise during installation, operation,
or maintenance.
• For further information or to resolve issues not covered in the manual, consult your
Siemens Milltronics representative.
The Manual
WARNING: relates to a caution symbol on the product, and means
that failure to observe the necessary precautions can result in
death, serious injury, and/or considerable material damage.
WARNING: means that failure to observe the necessary
precautions can result in death, serious injury, and/or considerable
material damage.
CAUTION: means that failure to observe the necessary precautions can
result in considerable material damage.
Note: means important information about the product or that part of the operating
manual.
IMPORTANT: All specifications are subject to change without notice.
Please ensure that any safety-related information is confirmed with a
qualified Siemens Milltronics representative.
WARNINGS:
• Changes or modifications not expressly approved by Siemens Milltronics
could void the user’s authority to operate the equipment.
• This equipment is intended to be used only in fully enclosed metal and
concrete containers.
Note: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his
own expense.

General Information
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.

General Information
The terminals for the power cable and the signal cable are behind the connection cover
on the left side of the housing. The signal cable must be fed in from the right through the
cable glands.
The end of the antenna must reach inside the vessel through the vessel nozzle (see
page 19).
If the device is rotated, return the orientation of the housing to its previous position with
reference to the flange, to ensure similar performance.

**An optional purging system can be installed between the flange and the horn antenna.
The system provides a 1/8” NPT inlet on the flange where cooling air or cleaning fluid
passes through the universal flange and exits the inside of the horn to clean it. The
customer will supply the purging medium by manual or automatic valve system. This
option is only available with universal flanges.
