SITRANS LR 460 – INSTRUCTION MANUAL

7ML19985JM01

SITRANS LR 460
SITRANS LR 460 is a 4-wire 24 GHz FMCW (Frequency Modulated/Continuous Wave) radar
level transmitter with advanced signal processing for continuous monitoring of solids up
to 100 meters. It is ideal for extreme dust and difficult applications. 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
LR 460 quite insensitive to vessel interferences.

Programming
SITRANS LR 460 carries out its level measurement function according to the set of built-in
parameter tables. You can make parameter changes via the Siemens Milltronics
handheld programmer, a PC running SIMATIC PDM or a HART handheld communicator.

Approvals and Certificates
SITRANS LR 460 is available with General Purpose approval, or approval for hazardous
areas containing dust. For details see Approvals on page 10.

System Implementation
SITRANS LR 460 supports HART communication protocol, or PROFIBUS PA (optional), and
SIMATIC PDM software.

Key considerations
•
•

Correct location is critical to a successful application.
Avoid reflective interference from vessel walls and obstructions by following the
guidelines below.

Nozzle design
•

Bottom edge of horn must project
from nozzle.

•

Nozzle must allow adequate
clearance to allow positioning if LR
460 has to be at an angle so that
emission cone perpendicular to
material surface.
Min. clearance:
10 mm (0.4")

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.

Installation in vessel with obstructions
Polarization Reference Point
Obstructions such as ladders, pipes, or the fill path, can cause false reflections. To avoid
this, use the Polarization Reference Point to orient the device.
•
•

A small center punch mark provides a polarization reference point.
To get the best signal, rotate the device till the Polarization Reference Point either
faces towards the obstruction, or faces away from the obstruction (at 180 degrees).

Note: the device can be rotated through 360
degrees without damage to the unit.

Air Purging System (Optional)
For more frequent cleaning, a purging system can be installed between the flange and the
horn antenna. The system provides an 1/8" inlet (female thread) on the flange where
cooling air or cleaning fluid passes through the flange and exits the inside of the horn to
clean it. The customer will supply the purging medium by a manual or automatic valve
system.
This option is only available with the universal flange for purging shown on page 17. 1

Notes:
• The Air Purge feature should not be activated with a dust cap in place.
• Purge duration, pressure, and interval, will vary with each application. It is the user’s
responsibility to determine the requirements depending on the application and
cleaning required.
• Short duration bursts of high pressure provide more effective cleaning than
continuous low pressure air.
• Some dust particles are highly abrasive and can be drawn into the inside of the horn
during purge cleaning, damaging the internal PTFE emitter of the antenna. A
replacement kit is available from your local Siemens Milltronics representative.
• It is the customer’s responsibility to ensure that any vacuum or pressure in the
measured vessel is maintained, considering the hole that passes through the
process connection and SITRANS LR 460 antenna system.

It is particularly useful for applications in areas of high humidity, or with bulk solids
with a high moisture content.
Two sizes are available, to fit the standard 3" and 4" horns.

Level application example
The application is a steel silo containing flour that takes an average 3 hours to fill and 3
weeks to empty.
Using the Easy Aimer, the LR 460 is oriented so that the emission cone is approximately
perpendicular to the material surface.
Fill rate = 0.09 m/minute (15.5 / 180). Response rate has been set to slow: 0.1 m/minute, or
slightly faster than the fill rate.

3.5.6. TVT (Auto False Echo Suppression) setup

Note: If the Reform parameter has been used to reshape the echo profile, Auto
False Echo Suppression must be re-enabled, to relearn the TVT curve
SITRANS LR 460 first learns the echo profile. Then the learned profile, or part of it,
is used to screen out false echoes. (See Auto False-Echo Suppression on page 73
for a more detailed explanation.)
To use Auto False Echo Suppression via SIMATIC PDM:
a. Determine Range (the distance within which the learned TVT will
replace the default TVT). Measure the actual distance from the
antenna reference point to the material surface using a rope or tape
measure, and make allowances for the actual location of the LR 460.
Subtract 2 m (6.56 ft) from this distance, and use the resulting value.
b. Open the menu Device – Auto False Echo Suppression.
c. Enter the value for Range and click Set Range.
d. Click Learn. The On and Off buttons disappear while the new curve
is being learned.
e. When the buttons reappear, click Close. Auto TVT is now on, and the
learned TVT curve will be used.
f. To turn Auto False Echo Suppression off or on, reopen menu Device
– Auto TVT and click On or Off.

SITRANS LR 460 – INSTRUCTION MANUAL

7ML19985JM01

SITRANS LR 460 is a long range FMCW (Frequency Modulated Continuous Wave) radar
transmitter. Radar level measurement uses the time of flight principle to determine
distance to a material surface.
FMCW radar transmits a continuous wave. The frequency of the wave is constantly
increasing: this is known as the sweep. By the time the first part of the wave has been
reflected off the target and returned to the device, the part of the wave that is just being
emitted is at a higher frequency. The difference in frequency between the transmitted and
received signals is proportional to time of flight.
Electromagnetic wave propagation is virtually unaffected by temperature or pressure
changes, or by changes in the vapor or dust levels inside a vessel.
SITRANS LR 460 consists of an enclosed electronic component coupled to an antenna
and process connection. The electronic component generates an electromagnetic signal
from 24.2 GHz to 25.2 GHz that is directed to the antenna.
The signal is emitted from the antenna, and the reflected echoes are digitally converted
to an echo profile. The profile is analyzed to determine the distance from the material
surface to the reference point on the instrument. This distance is used as a basis for the
display of material level and output.

Measurement Response
The measurement response (response rate) limits the maximum rate at which the
display and output respond to changes in the measurement. Once the real process fill/
empty rate (m/s) is established, a response rate can be selected that is slightly higher
than the application rate. The response rate automatically adjusts the filters that affect
the output response rate.
There are three preset options: slow, medium, and fast.

Echo Processing
Profile monitoring via SIMATIC PDM
To view an echo profile open the menu View – Profile.

echo profile
TVT curve

echo distance

You will see the echo profile, the Time Varying Threshold (TVT), and a vertical line
indicating the distance from the sensor to the echo selected.
Echo strength is indicated on the Profile (dB) vertical axis. The distance shown on the
horizontal axis is the distance from the sensor to the target.

Time Varying Threshold (TVT)
The TVT is a threshold curve used to detect the presence of significant echoes. See Auto

False-Echo Suppression on page 73 for more detail.

Echo selection
The device considers all peaks that are above the TVT as a potential good echo.
Each peak gets a rating based on its strength, area, height above the TVT, and other
parameters. The true echo is selected based on the setting for Echo Algorithm on page 54.

Page A-72

SITRANS LR 460 – INSTRUCTION MANUAL

7ML19985JM01

False echoes can appear during the receive cycle. They can be caused by interference
with the emission cone, or by internal impediments like a ladder rung, and are usually
indicated by an incorrect high level reading.

Make allowance for the beam
spreading, to avoid interference
with the emission cone.

Polarization reference point
You can rotate the device to minimize false echoes. See Polarization Reference Point on
page 14 for details.

Auto False-Echo Suppression
Note: If possible, rotate the instrument before using Auto False-Echo Suppression, to
lower the amplitude of false echoes.
The TVT adjustment parameters allow you to manipulate the TVT (Time Varying
Threshold), so that SITRANS LR 460 will ignore false echoes.
The default TVT hovers above the echo profile, and effectively screens out small false
echoes. But if an obstruction is causing a large echo before the material level echo, that
echo will rise above the default TVT.
1.
2.

Set Auto False-Echo Suppression to Learn. The instrument learns the echo profile at
that moment1. The new TVT follows the echo profile, so that nothing rises above it.
Set Auto False Echo Suppression Distance so that the learned TVT will be used in
the area of the false echoes, which will not rise above it. From that point on the
default TVT will be used. The material level echo rises above this, and is selected as
the true echo.

See page 58 for examples of the echo profile before and after using Auto False-Echo
Suppression.

Set Auto False-Echo Suppression to Learn when the material level is substantially lower than

Near Range (Blanking)
Note: Auto False-Echo Suppression is generally recommended in preference to using
Near Range.
Near Range allows you to set a distance in front of the antenna, within which any echoes
will be ignored.

Echo confidence
Echo confidence is an internally generated numeric rating given to an echo based on its
relative strength, area, and height.

Loss of Echo (LOE)
A loss of echo (LOE) occurs when the calculated measurement is judged to be unreliable
because the echo confidence value has dropped below the echo confidence threshold.
The LOE timer starts running, and if the LOE condition persists beyond ten minutes (the
time limit set by the LOE timer) the Unreliable Echo indicator replaces the Reliable Echo
indicator.
Reliable Echo indicator

Unreliable Echo indicator

While LOE is pending the x flashes, alternating with the two horizontal bars. When LOE
becomes active, the x becomes solid and the auxiliary display shows fault code S: 0.
Upon receiving a reliable echo, the loss of echo condition is aborted, the Reliable Echo
indicator reappears, and the reading returns to the current level.

LOE Timer
The LOE timer determines the time (in minutes) to elapse after the last valid reading
before Fail-safe mode is activated. When the LOE timer expires, the material level to be
reported is determined by Fail-safe Mode.

Fail-safe Mode
Fail-safe mode defines the reaction of the device if a Fail-safe condition is detected, so
that the process will be put into a safe state in the event of a fault or failure. The
particular application determines whether a high or low level is safe.

Appendix F: HART Information Structure
SITRANS LR 460 detects a material level via the sensor, and then processes that
information to provide a measured value. The measured value is conveyed as a digital
signal.
The LR 460 device design enables it to provide outputs to two different channels:
• a 4-20 mA channel
• a digital channel

Block Model for recording and processing measured values
The LR 460 follows a profile block model similar to a PROFIBUS Profile 3.01, Class B,
PA device. The functions of the device are divided into blocks.
Information is recorded by the sensor, then passed through the Level Transducer Block to
two independent Analog Input Function Blocks (AIFB1 and AIFB2).
The parameters used to configure the Function Blocks are standard profile parameters,
following a convention similar to that used in the PROFIBUS Profile Structure. They can
be modified by HART communications via PDM.

Page F-90

SITRANS LR 460 (HART) – INSTRUCTION MANUAL

7ML19985JM01

The two AIFBs are identical, but completely independent of each other. They utilize the
output from the Level Transducer Block.

AIFB1
The output of Analog Input Function Block 1 supplies the measured value and associated
status information as a digital signal to two communication channels:
•
•

via the mA Output Block to a 4 to 20 mA channel
to the HART digital channel, as the HART Primary Variable. This can only be
viewed via the HART digital channel.

AIFB2
The output of Analog Input Function Block 2 supplies the measured value and associated
status information as a digital signal to the HART digital channel, as the HART Secondary
Variable. This can only be viewed via the HART digital channel.

Input information is always requested at every bus scan and is set up as cyclic data.
Configuration information is only needed periodically and is set up as acyclic data.

Cyclic Data

Slot 0 always transmits AIFB1 information1; slot 1 defaults to Free Place, but can be
changed to AIFB2 information. If you do not wish to have data transmitted, then you must
use a Free Place module in that slot.
Each of the two Analog Input Function Blocks can be set up to return Level, or Distance.
Within the function blocks, the values are scaled according to the user requirements (see
Analog Input Function Blocks 1 and 2 on page 102 for details).

See Analog Input Function Blocks 1 and 2 on page 102 for more information.

When you configure SITRANS LR 460 on the PROFIBUS PA bus, there are two slots
available for modules.

AIFB1 and AIFB2 return 5 bytes of data each:

The first 4 bytes are the floating point representation (IEEE) of the variable. The variables
are the outputs of the function block. The 5th byte is the status word and the list of
possible values is given in the chart below.
The 5 bytes must be read consistently, in a contiguous chunk: they cannot be read byte by
byte, and cannot suffer an interrupt. If you are using an S7-300 / 400, you will need to use
SFC14 DPRD_DAT: Read Consistent Data of a Standard PD Slave.

PROFIBUS Level Device Design
The device follows the profile block model and is implemented as a Profile 3.01, Class B,
PA device. Standard profile parameters are used to program the Level Transducer Block.

Block Model for recording and processing measured values
The functions of the device are divided into blocks for different areas of responsibility.
They can be parameterized by acyclic data transfer via PDM.

The device is implemented with one Level Transducer Block (LTB), and two Analog Input
Function Blocks (AIFB1 and AIFB2).

Level Transducer Block (LTB)

Analog Input Function Blocks AIFB1 and AIFB2
The two AIFBs are completely independent of each other. They utilize the output from the
TB, and apply any required quality checks, scaling, and Fail-safe operation selections.
The output of an Analog Input Function Block supplies the measured value and
associated status information to PROFIBUS PA, via cyclic data transfer.

7ML19985JM01

SITRANS LR 460 (PROFIBUS PA) – INSTRUCTION MANUAL

Page J-99

mmmmm

The Level Transducer Block (LTB) carries out adjustments to the sensor, such as level
calibration. It supplies the outputs utilized by either or both of the AIFBs.

J: Profile structure PA

All data is viewed from the perspective of the DCS or PLC, so information from the sensor
is an input.

Description of the blocks
Level Transducer Block function groups
Note: Primary Value (PV) is the default measured value; Secondary Value 1 (SV1) is an
equivalent value.
The figure below shows the signal flow of measured values from the sensor through the
Level Transducer Block into the output value (Primary Value/ Level; Secondary Value 1 /
Level; or Secondary Value 2 /Distance. The LTB implements all of the basic parameters

How the Level Transducer Block works:
1.

The sensor technology block selects the proper echo. See Echo selection on page
72 for more detail.
The sensor value (in sensor units) is checked to see if it is within its measuring limits.
If the limit is exceeded, this results in a Bad status and the error message Failure in
measurement. The sensor value is stored in Sensor Value.
The analog signal from the sensor is transformed into a digital signal.
A Sensor Offset (default 0) provides compensation if necessary for differences
between the vessel reference point and the sensor reference point.

A Linearization module is required by the PROFIBUS PA specifications. The
Linearization block is turned off in SITRANS LR 460.

Electronics temperature
The Level Transducer Block also monitors the internal temperature of the device
electronics. If the temperature exceeds permitted limits, it does not change the sensor
value, but it does change the status.The permitted limits correspond to those of the
permitted ambient temperature.
If a temperature limit is exceeded, the status changes. Peak indicators1 allow you to
check the maximum and minimum temperatures that have occurred.

Analog Input Function Blocks 1 and 2
There are two identical Analog Input Function Blocks which operate independently. The
figure below shows how measured values are processed within the Analog Input
Function Block (AIFB1 or AIFB2) to produce the device output, which is communicated via
cyclic transfer to PROFIBUS PA, and displayed on the LCD.

The output from the Level Transducer Block can be called the Primary Value (or
Secondary Value). When it becomes the input to the AIFB, it is called the Process
Variable.
Page J-102

SITRANS LR 460 (PROFIBUS PA) – INSTRUCTION MANUAL

7ML19985JM01

Output Conversion
Values transmitted by the TB have a status attached. The decision on what to do with
each value is made by the Analog Input Function Block.

Device/ Input Simulation
The input can be a simulated value instead of a TB OUT value. This allows the AI block to
be tested independently of the characteristics of the environment.

Fail-safe
•

If the status of the Primary Value or Simulation Value is bad, the fault logic can
output either the last usable measured value, or a given substitute value.

Device / Output Simulation
One of three settings can be selected. The result is the output parameter (OUT).

This value is filtered using a first order filter based on a time constant provided by
the user.
The status of the Process Variable (input value) is checked. If the status is Bad, a
Fail-safe condition occurs. The output is determined by the Fail-safe Mode of the
block.
The target mode parameter allows the entire AI block to be overridden by a Manual
Out value.
The value is checked against the user parameterized warning and alarm limits.
(There is an upper and lower warning limit and an upper and lower alarm limit. The
unit of the limits corresponds to the unit of the output range. A hysteresis parameter
prevents toggling in the Status field of the OUT value.)
The OUT VALUE parameter is the value for the cyclic data transfer.

finite number of steps.
ambient temperature: the temperature of the surrounding air that comes in contact with the
enclosure of the device.
antenna: an aerial which sends out and receives a signal in a specific direction. There are four
basic types of antenna in radar level measurement, horn, parabolic, rod, and waveguide.

reading of false echoes. (See TVT.)
Auto False-Echo Suppression Distance: defines the endpoint of the TVT distance. (See TVT.)
This is used in conjunction with auto false echo suppression.
beam angle: the angle diametrically subtended by the one-half power limits (-3 dB) of the
sound beam.
beam spreading: the divergence of a beam as it travels through a medium.
blanking: see Near Range.
capacitance: the property of a system of conductors and dielectrics that permits the storage of
electricity when potential differences exist between the conductors. Its value is
expressed as the ratio of a quantity of electricity to a potential difference, and the unit is a
Farad.
confidence: describes the quality of an echo. HIgher values represent higher quality.
Confidence threshold defines the minimum value.
damping: term applied to the performance of an instrument to denote the manner in which the
