General Information
General Information
The Manual
Refer to this manual for proper installation, operation and maintenance of the SITRANS
LR 400 Radar Level Instrument.
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 contents of the manual shall not become part of or modify any prior or existing
agreement, commitment or relationship. The Sales Contract contains the entire
obligation of Siemens Milltronics. The warranty contained in the contract between
the parties is the sole warranty of Siemens Milltronics.
WARNING means that failure to observe the necessary precautions can result in
death, serious injury, and/or considerable material damage.
Notemeans important information about the actual product or that part of the
operating manual.
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.
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.
IMPORTANT: All specifications are subject to change without notice.
Please ensure that any safety-related information is confirmed with a
qualified Siemens Milltronics representative.

General Information
Qualified personnel
Qualified personnel are familiar with the installation, commissioning, and operation of
this equipment. In addition the person must be:
• trained and authorized to operate and service equipment/systems in accordance
with established safety procedures relating to electrical circuits, high pressures and
aggressive media.
• trained in the proper care and use of protective equipment in accordance with
established safety practices.
• trained in rendering first aid.
WARNINGS:
• 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, otherwise protection provided by equipment may be impaired.
IMPORTANT: The information in Appendix IV of this manual is not
applicableto theflangesmarkedwithserialnumbersfrom 020102-001 to
020102-128. These flanges are intended for non-pressure applications in
North America only.

General Information
SITRANS LR 400
The SITRANS LR 400 Radar Level Instrument is designed for medium to long range level-
measuring of solids and liquids in storage vessels. SITRANS LR 400 uses a high
microwave frequency and operates reliably even with poorly reflecting measuring media.
The narrow antenna beam results in a sharp radiation cone, which makes the SITRANS
LR 400 quite insensitive to vessel interferences.
Structure
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 device can be separated into electronic and mechanical sections at the threaded ring.
An optional temperature extension is positioned between the threaded ring and the
process flange.
The end of the antenna must reach inside the vessel through the vessel nozzle (see
page 17).
After servicing, return the orientation of the housing to its previous position with
reference to the flange, to ensure similar performance.
