Safety Guidelines
Warning notices must be observed to ensure personal safety as well as that of others, and to
protect the product and the connected equipment. These warning notices are accompanied by
a clarification of the level of caution to be observed.1
FCC Conformity
US Installations only: Federal Communications Commission (FCC) rules
SITRANS LR260
SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of
solids and liquids in storage vessels including extreme levels of dust and high temperatures, to
a range of 30 m (98.4 ft).
The instrument consists of an electronic component coupled to a horn antenna with an
integral Easy Aimer and flange for quick and easy positioning. A dust cover or air purging are
available as options.
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.
WARNING1: means that failure to observe the necessary precautions can result
in death, serious injury, and/or considerable material damage.
Note: means important information about the product or that part of the operating manual.
1. This symbol is used when there is no corresponding caution symbol on the product.
WARNING: Changes or modifications not expressly approved by Siemens
Milltronics could void the user’s authority to operate the equipment.
Notes:
• 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 Operating Instructions, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is
likely to cause harmful interference to radio communications, in which case the user will
be required to correct the interference at his own expense.
WARNING: SITRANS LR260 is to be used only in the manner outlined in this
manual, otherwise protection provided by the equipment may be impaired.
Note: This product is designated as a Pressure Accessory per Directive 97 / 23 / EC, and is
not intended for use as a safety device.

SITRANS LR260 supports PROFIBUS PA communication protocol, and SIMATIC PDM software.
Signals are processed using Process Intelligence which has been field-proven in over 
1, 000,000 applications worldwide (ultrasonic and radar). This device supports acyclic
communications from both a PROFIBUS Class I and Class II master.

Installation1
Installation guidelines
• Provide easy access for viewing the display and programming via the hand programmer.
• Provide an environment suitable to the housing rating and materials of construction.
• Provide a sunshield if the device will be mounted in direct sunlight.
Nozzle design
• The end of the horn must protrude a minimum of
10 mm (0.4”) to avoid false echoes being reflected
from the nozzle.
• Optional antenna extension: 100 mm (3.93"),
200 mm (70.9"), 500 mm (19.69"), 1000 mm (39.4")2
WARNINGS:
• This product is designated as a Pressure Accessory per Directive 97 / 23 / EC, and
is not intended for use as a safety device.
• Do not attempt to loosen, remove, or disassemble process connection or
instrument housing while vessel contents are under pressure.
• Improper installation may result in loss of process pressure.
WARNINGS:
• Installation shall only be performed by qualified personnel and in
accordance with local governing regulations.
• Materials of construction are chosen based on their chemical compatibility (or
inertness) for general purposes. For exposure to specific environments, check
with chemical compatibility charts before installing.
Notes:
• For European Union and member countries, installation must be according to ETSI EN
302372.
• The Process Device Tag shall remain with the process pressure boundary assembly1. In
the event the instrument package is replaced, the Process Device Tag shall be transferred
to the replacement unit.
• SITRANS LR260 units are hydrostatically tested, meeting or exceeding the requirements
of the ASME Boiler and Pressure Vessel Code and the European Pressure Equipment
Directive.
1. The process pressure boundary assembly comprises the components that act as a barrier against
pressure loss from the process vessel: that is, the combination of process connection body and
emitter, but normally excluding the electrical enclosure.
2. Extensions are not recommended for applications where there may be excessive visible vibration.
Please consult factory for more information.

Nozzle location
• Keep emission cone free of
interference from ladders, pipes,
I-beams or filling streams.
• Avoid central locations on tall,
narrow vessels.
• Align the antenna so that the
radar cone is perpendicular to the
surface of the monitored material,
if possible.

Note: Beam angle depends on horn
size.
WARNING: The user is responsible for the selection of bolting and gasket materials
which will fall within the limits of the flange and its intended use, and which are
suitable for the service conditions.
WARNINGS:
The DC input terminals shall be supplied from a source providing electrical
isolation between the input and output, meeting the applicable safety
requirements of IEC 61010-1.
All field wiring must have insulation suitable for rated voltages.

Connecting SITRANS LR260
1. Use a 2 mm Allen key to loosen the lid-lock set screw then using a screwdriver for
leverage if necessary, unscrew the cover.
2. Strip the cable jacket for approximately 70 mm (2.75") from the end of the cable, and
thread the wires through the gland1.
3. Connect the wires to the terminal as shown (SITRANS LR260 is not polarity sensitive)
4. Ground the device according to local regulations.
5. Tighten the gland to form a good seal.
6. Close the lid and secure the locking ring beforeprogramming and calibration..
WARNINGS:
• Check the device nameplate and process device tag, to verify the approval rating.
• Use appropriate conduit seals to maintain IP or NEMA rating.
•Read
Wiring setup for hazardous area installations on page 7.
Note:
• For detailed wiring instructions refer to the full Operating Instructions.
• Use twisted pair cable: AWG 22 to 14 (0.34 mm² to 2.5 mm²).
• Separate cables and conduits may be required to conform to standard instrumentation
wiring practices, or electrical codes.
1. If cable is routed through conduit, use only approved suitable-size hubs for waterproof applications.
Notes:
• PROFIBUS PA must be terminated at both extreme ends of the cable for it to work
properly.
• Please refer to the
PROFIBUS PA User and Installation Guidelines (order number 2.092),
available from www.profibus.com, for information on installing PROFIBUS devices.
