US Installations only: Federal Communications Commission (FCC)
rules
Canadian Installations only: Industry Canada (IC) rules
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 instruction manual, may cause harmful

likely to cause harmful interference to radio communications, in which case the user will
be required to correct the interference at his own expense.
Notes:
• This device shall be installed and operated in a completely enclosed container to prevent
RF emission, which otherwise can interfere with aeronautical navigation. Installation
shall be done by trained installers, in strict compliance with the manufacturer’s
instructions.
• The use of this device is on a ’no-protection non-interference’ basis.
- The user shall accept operations of high powered radar in the same frequency band,
which may interfere with or damage this device.
- The user is responsible for removing, at the user’s expense, any device found to
interfere with primary licensing operations.

The Manual
SITRANS LR460 supports HART communication protocol, or PROFIBUS PA, and SIMATIC PDM
software, and this manual is in 3 parts:
•
SITRANS LR460 (HART/PROFIBUS PA) on page 3: information for both HART/
PROFIBUS PA models, including:
• power, approvals, installation, connecting, programming, activating, quick start via
handheld programmer, communications via HART or PROFIBUS PA, quick start via
SIMATIC PDM
•
Hazardous area installations on page 15
• SITRANS LR460 PROFIBUS PA wiring on page 8
SITRANS LR460 (HART/PROFIBUS PA)
The SITRANS LR460 is a 4-wire 24 GHz FMCW radar level transmitter with extremely high
signal-to-noise ratio and advanced signal processing for continuous monitoring of solids up to
100 m (328 ft). It is ideal for measurement in extreme dust. The Easy Aimer design makes it
easy to install the device and orient the signal towards the material angle of repose. The high
frequency signal creates a narrow emission cone, which makes the LR460 quite insensitive to
vessel interferences.

WARNING: SITRANS LR460 is to be used only in the manner outlined in this
manual, otherwise protection provided by the equipment may be impaired.
Installation shall only be performed by qualified personnel and in
accordance with local governing regulations.
Notes:
• For European Union and member countries, installation must be according to ETSI EN
302372.
• Refer to device nameplate for approval information.
• Use appropriate conduit and conduit fittings or cable glands, to maintain IP or NEMA
rating.
• Observe maximum permissible ambient and process temperatures.
• For US and Canadian installations, see FCC and IC Conformity on page 2.
Notes:
• Provide easy access for viewing the display and programming via the handheld
programmer.
• Provide an environment suitable to the housing rating and materials of construction.
• Provide a sun shield if the device is mounted in direct sunlight.

Key considerations
• Nozzle design and nozzle location are critical to a successful application.
• Avoid reflective interference from vessel walls and obstructions by following the
guidelines below.
Nozzle design
Nozzle location
• Locate antenna at least 1 meter away from
side wall.
• Keep emission cone free of interference
from ladders, pipes, I-beams or filling
streams.
• Make allowance for beam spread to avoid
interference with the emission cone.
Device orientation
Align the antenna so that the radar cone is
perpendicular to the surface of the monitored
material, if possible.
Easy Aimer Installation
1. Holding the electronics enclosure firmly,
loosen the Easy Aimer ball locking bolts and
gently reposition the enclosure (see
Nozzle
design
above).
2. Direct SITRANS LR460 so the horn antenna
is pointed at an angle perpendicular to the material surface, if possible. (As a guide, aim
the beam at a point approximately 2/3 of the way across the tank diameter.)
3. When the desired position is reached, re-tighten the 5 bolts to 15-23 N m (11 to 17 Lbf-ft).
Note: When the Easy Aimer ball is loosened,
the device is free to tilt to a maximum of 30°.
min. clearance
10 mm (4")
• Bottom edge of horn must project from nozzle.
• Nozzle must have adequate clearance to allow LR460 to be positioned at an angle (see
Device orientation below).

Wiring
Connecting SITRANS LR460
1. Release the cover lock on the enclosure with a 3 mm Allen key and unscrew the cover.
(Use a screwdriver for extra leverage, if required.)
2. Loosen the cable gland and push the power cable through until it reaches the terminal
strip.
3. Go to
SITRANS LR460 HART wiring on page 7 or SITRANS LR460 PROFIBUS PA wiring
on page 8 for next steps.
WARNINGS:
• Turn off power to the device before removing the cover in a hazardous area.
• All field wiring for AC models must have insulation suitable for at least 250 V.
• The DC input terminals shall be supplied from a source that provides electrical
isolation between the input and the output, in order to meet the applicable safety
requirements of IEC 61010-1.
• The equipment shall be protected by a fuse or circuit breaker of up to 16 A in the
building installation.
• A circuit breaker or switch in the building installation, marked as the disconnect
switch, shall be in close proximity to the equipment and within easy reach of the
operator.
• To avoid short-circuits, do not connect a load resistance with bare wires inside the
connection box.
Notes:
• AC and DC input circuits: min. 14 AWG (2.5 sq. mm) copper wire.
• Lay power cables separately from communication wiring.
• Recommended torque on terminal clamping screws: 0.5 to 0.6 N m (0.37 to 0.44 Lbf-ft).

Connecting HART
4. Connect the earth conductor of the power supply to
the earth terminal on the metal bracket inside
the enclosure. Adjust the cable length so that the
earth conductor would be last to disconnect if cable
is pulled.
5. Tighten the cable gland and check the strain relief
(pull and turn).
Note: LR460 HART requires no power from the 4-20 mA loop.

Power Demands
To determine how many devices can be connected to a bus line, calculate the combined
maximum current consumption of all the connected devices: 10.5 mA for SITRANS LR460.
Allow a current reserve for safety.
Bus Termination
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.
Install in accordance with
PROFIBUS PA User and Installation Guidelines (order number 2.092),
