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
SITRANS LR 400 is a long-range FMCW radar level transmitter. A solids version (7ML5420)
incorporates the Easy Aimer design for use in solids, especially conditions of extreme
dust. A liquids version (7ML5421) is available for use in liquids storage, ideal for low
dielectric liquids, and high pressure applications or applications requiring gas safety
approvals. On both versions, the narrow antenna beam results in a sharp emission cone,
which makes 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 antenna end must reach inside the vessel through the vessel nozzle (see page 13).
If the device is rotated, return the orientation of the housing to its previous position with
reference to the enclosure, to ensure similar performance.
Note: This manual applies to the solids version only. Please see Instruction
Manual 7ML19985FH05 for information about the SITRANS LR 400 liquids version.

Installation

Mounting Location
Recommendations
• Position device with easy access for viewing display and programming via handheld
programmer.
• Mount device in an environment suitable to the housing rating and the materials of
construction.
• Mount the unit more than 1 m away from the vessel walls, pipes and other
assemblies as well as the filling stream, because all these influences will become
noticeable as reflective interference. Align the antenna so that the radar cone
intersects the surface of the measuring medium as vertically as possible.
Precautions
• Do not mount in direct sunlight without the use of a sun shield.
• Avoid proximity to high voltage or current wiring, high voltage or current contacts,
and to variable frequency motor speed controllers.
• Avoid interference to emission cone from obstructions or from fill path.
• Avoid central locations on vessel.
Notes:
• SITRANS LR 400 is rated for Type 4X/NEMA 4X, Type 6/NEMA 6, IP67.
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 on page 92.
Provide a warning sign and/or touch guard if the surface of the
measuring instrument can become hotter than 70 °C (158 °F) in use.
WARNING:
• Improper installation may result in loss of process pressure.

Correct Installation in Mounting Nozzle
The bottom edge of the antenna must project into the vessel to avoid reflective
interference at the wall of the nozzle. Above 6" process nozzle diameter, the antenna does
not need to project beyond the nozzle unless the radiation cone (the extension of the
antenna’s angle) touches the nozzle wall.

Installation
Connecting SITRANS LR 400:
1. Release the cover lock on the connection box with a 3 mm Allen key.
2. Unscrew the cover from the connection box.
3. 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. Adjust the cable length so that the earth conductor would be last to
disconnect if cable is pulled.
5. Tighten the cable screw gland and check the strain relief (pull and turn).
6. Screw the cover onto the connection box and tighten it without using a tool. The
sealing ring must be clean and undamaged.
7. Reattach the cover lock on the connection cover.
8. Connect the earth terminal located between the screw-type cable glands to a
ground connection at your vessel by using a cable with a diameter greater than or
equal to 2.5 mm2.
For error-free communication via the HART protocol, a load of at least 230 Ωmust be
available in the signal circuit.
WARNING:
• To avoid short-circuits, do not connect a load resistance with bare wires in
the connection box.
• The housing cover must not be unscrewed in a hazardous area when the
device is under voltage (power supply, digital outputs on external supply).

Start Up
Start Up
Self-test
When power is supplied, the device performs a self-test. Then, when the multi-display
appears, the device is ready for programming.
Multi-display
The multi-display shows on the LCD after a successful self-test with the first line showing
level output and the second line showing signal-to-noise ratio (factory setting):
Local Programming
When the multi-display appears on the LCD, begin local
programming using the hand programmer. To access the
parameter settings, press LEFT once. Main Menu is visible
as the first LCD line. Then, program the unit beginning with the
Auto-Setup parameters.
Auto-Setup
After switching on 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
(see page 27):
• The language of the local user interface
• The unit of length of the measured level
• The nozzle height in the selected unit of length
•Thevessel height in the selected unit of length
• The LRV (lower range value) as a distance from the bottom of the vessel
• The URV (upper range value) as a distance from the bottom of the vessel
• The damping of the measured level in seconds
• The application type
• The bus address by PROFIBUS PA communication (on PROFIBUS models)
Enter the necessary values as described in Parameters starting on page 26.
If the multi-display does not appear or displays incorrect measured values after Auto-
Setup, proceed as described in
Troubleshooting on page 72.
