SITRANS LR 460
SITRANS LR 460
SITRANS LR 460 is a long-range FMCW radar level transmitter for level measurement of
solids. It can be used in high pressure applications or applications requiring gas safety
approvals. The Easy Aimer design makes it easy to set up the device even in conditions of
extreme dust. The narrow antenna beam creates a sharp emission cone, which makes the
LR 460 quite insensitive to vessel interferences.

• SITRANS LR 460 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.
• Improper installation may result in loss of process pressure
Notes:
• Installation must be according to ETSI EN 302372.
• Refer to device nameplate for approval information.
• For Type 4X/NEMA 4X, Type 6/NEMA 6, IP67 type of protection use only approved,
suitable sized hubs for watertight applications.
• Observe all maximum permissible ambient and process temperatures. Refer to

PA: Remote Operation
Remote operation via PROFIBUS PA
SITRANS LR 460 is a Class B, Profile Version 3.0, PA device. It supports Class 1 Master for
cyclic and acyclic data exchange, and Class 2 for acyclic services. The full range of
SITRANS LR 460 functions is available only over a PROFIBUS PA network.
PROFIBUS PA is an open industrial protocol. Full details about PROFIBUS PA can be
obtained from PROFIBUS International at www.profibus.com.
To use PROFIBUS PA, you will need a PC configuration tool: we recommend
SIMATIC PDM. Please consult the operating instructions or online help for details on
using SIMATIC PDM. (You can find more information at www.fielddevices.com: go to
Products and Solutions > Products and Systems > Process Device Manager.)
SIMATIC PDM
SIMATIC PDM is a software package for designing, parameterizing, commissioning,
diagnosing and maintaining SITRANS LR 460 and other process devices.
SIMATIC PDM contains a simple process monitor of the process values, alarms and
status signals of the device. Using SIMATIC PDM you can
•display
•set
•change
•compare
• check the plausibility of
•manage
• simulate
process device data.
Device Description
In order to use Process Device Manager (PDM) with PROFIBUS PA, you will need the
Device Description for SITRANS LR 200, which will be included with new versions of
PDM. You can locate the Device Description in Device Catalog, under Sensors/Level/
Echo/Siemens Milltronics. If you do not see SITRANS LR 460 under Siemens Milltronics,
you can download it from our web site. Go to the SITRANS LR 460 product page at https:/
/pia.khe.siemens.com/index.asp?Nr=7427 and click Downloads. After downloading the
DD file, you need to execute DeviceInstall.

PA: Remote Operation
Configuration
To configure a PROFIBUS PA Class 1 Master (for example, a PLC), you will need a GSD
file.
The GSD file
The GSD file SIEM810F.gsd is available from the SITRANS LR 460 product page on our
web site. Go to https://pia.khe.siemens.com/index.asp?Nr=7427 and click Downloads.
Download the DeviceInstall, and run it from your computer. This will install the GSD file
into your system (as long as you are using SIMATIC software).
Setting the PROFIBUS address
When your instrument is shipped, the PROFIBUS address is set to 126. You can set it
locally (see
Setting the PROFIBUS address via the handheld programmer
on page 27) or
remotely via the bus, using a parameterization tool such as SIMATIC PDM (see
Address
(default 126)
on page 58).
PROFIBUS address
Bus Termination
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 LR 200.
Allow a current reserve for safety.
Cyclic versus Acyclic Data
When you request data from a device via PROFIBUS PA, you have two choices. Cyclic
data is provided at every bus scan: acyclic data is requested and provided as needed.
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.
Note: If you are not using SIMATIC software, you can download the GSD file
separately, and import it with the software you are using.
Values Range: 0 to 126
Pre-set: 126
Note: 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.

PA: Remote Operation
Cyclic Data
When you configure SITRANS LR 460 on the PROFIBUS PA bus, there are two slots
available for modules.
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, Distance, or
Volume. Within the function blocks, the values are scaled according to the user
requirements (see
Analog Input Function Blocks 1 and 2
on page 55 for details).
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.
Status Byte
Note: Each of the slots has to have a module defined in it.

Diagnostics
All diagnostic information shown below is viewable via PDM.
Diagnosis reply (applies only to cyclic masters)
This is a response to a GET-DIAG message.
During DPV0 data exchange, the PROFIBUS PA slave will notify the Master when a
serious error occurs. The Master will then send a Diagnosis request. The reply to this
request is normally logged in the PLC and is referred to as the "Hex values."
The reply may contain two parts. The first part is 6 bytes long and is defined by the
PROFIBUS standard. If there is a second part, it is called the ’extended diagnostic’ and it
is eight bytes long. The last four bytes of the extended diagnostic message give the error
code shown below. (The same information is also available acyclically via the Diagnosis
Object.
Status Codes for Bad Quality
Values in hex notation Description
0x10 The LOE timer has expired: this could be caused by
LOE or by a sensor malfunction: value is BAD.
0x01 There is an error in the configuration of the function
blocks in PROFIBUS PAa.
0X1F
The function block has been placed out of service.
(You will see this only if you read status word via
acyclic services, after placing the function block out of
service.)
0xC4 Bad configuration: value is BAD.
0XDE AI block out of service: value is BAD.

PROFIBUS PA Profile Structure
PROFIBUS Level Device Design
The device follows the profile block model and is implemented as a Profile 3.0, 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 Physical Block (PB1), one Level Transducer Block
(LTB1), and two Analog Input Function Blocks (AIFB1 and AIFB2).
All data is viewed from the perspective of the DCS or PLC, so information from the sensor
is an input.
Transducer Block (TB)
The Level Transducer Block (LTB) carries out adjustments to the sensor, such as level
calibration and volume calibration. It supplies the outputs utilized by either or both of the
AIFBs.
Analog Input Function Blocks AIFB1 and AIFB2
The two AIFBs are completely independent of each other. They utilize the output from the
Level TB, and apply any required quality checks, scaling, and Failsafe 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.

Description of the blocks
Transducer block function groups
The figure below shows the signal flow of measured values from the sensor through the
Transducer block into the output value (Primary Value/ Level or Volume; Secondary Value
1 / Level; Secondary Value 2 /Distance 1; or Secondary Value 3 / Distance 2). The Level TB
implements all of the basic parameters (see parameter diagram on page 54), including
level to volume calculation, if that option has been selected.
How the LTB works:
1. The sensor technology block selects the proper echo. For an explanation of sensor
technology, please refer to
Appendix B: Technical Reference
, page 82 onwards.
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 changes in the
sensor.

2. Level Calibration is a linear transfer function that converts a sensor value to a level
value. The level value is used for volume calculation, if that function is enabled.1
3. Then linearization can be carried out to accommodate complex tank shapes, or to
provide level to volume conversion.
4. The LTB provides four possible outputs
• Primary Value (PV) / Level or Volume
• Secondary Value 1 (SV1) / Level
• Secondary Value 2 (SV2) / Distance1 (sensor units)
or
• Secondary Value 3 (SV3) / Distance 2 (any level units, except %)

Electronics temperature
The 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
The figure below shows how measured values are processed within the two Analog
Input Function Blocks (AIFB1 and AIFB2) to produce the device outputs, which are
communicated via cyclic transfer to PROFIBUS PA, and displayed on the LCD.

How the AIFBs work
The Analog Input Function Blocks allow you to control modifications to the output value
(PROFIBUS cyclic data).
Output Conversion
Values transmitted by the Level 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.
Failsafe
• 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).
AIFB execution steps:
The AIFBs can provide a linear conversion to any desired units.
1. The input value is normalized (Scaling Input)
Process Variable range applies to any of the four LTB values. (Units of the Process
Variable scale are the same as the units used for the LTB output.) Output units
together with Process Variable range determine how the LTB output is converted to
whatever units the customer wants.
Setting description Output value
AUTO automatic the automatically-recorded measured value
MAN manual a manually-set fixed simulation value
O/S function block disabled the preset safety value.

Profile structure
2. The scaling output is applied.
For example:
3. This value is filtered using a first order filter based on a time constant provided by
the user.
4. The status of the Process Variable (input value) is checked. If the status is Bad, a
Failsafe condition occurs. The output is determined by the Failsafe Mode of the
block.
5. The target mode parameter allows the entire AI block to be overridden by a Manual
Out value.
6. 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.)
7. The OUT VALUE parameter is the value for the cyclic data transfer.

Parameters
2.5.3. Echo Sampling
2.5.3.1. Sampling up1
Once echo is outside the window, a specified number of consecutive
echoes must appear above the echo locked onto, before measurement is
accepted as valid.
2.5.3.2. Sampling down1
Once echo is outside the window, a specified number of consecutive
echoes must appear below the echo locked onto, before measurement is
accepted as valid.
2.5.3.3. Window1
A "distance window" centered on the echo, used to derive the reading.
When a new measurement is in the window, the window is re-centered
and the reading is calculated (see Display before Auto False Echo

Principles of Operation
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. The transmit time is directly proportional to the distance to
the material.
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.
If none of the preset options is satisfactory, the filters can be adjusted individually.

F: Technical Reference
Echo Lock
When the echoes are received, the relevant echo algorithm is applied to determine the
true material echo. If the selected echo is within the window, the window is then
centered about the echo. Otherwise the window widens with each successive shot until
the selected echo is within the window, which then returns to its normal width.
Echo Lock selects the measurement verification process:
• When Echo Lock is Off, SITRANS LR 460 responds immediately to a new
measurement (within the restrictions set by the Maximum Fill / Empty Rate).
However, measurement reliability is affected.
• When Maximum Verification or Material Agitator is selected, a new measurement
outside the Echo Lock Window must meet the sampling criteria.
• When Total Lock is selected, Echo Lock Window is pre-set to 0, and the window is
automatically calculated after each measurement.
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 Failsafe mode is activated. When the LOE timer expires, the material level to be
reported is determined by Failsafe Mode.
Failsafe Mode
Failsafe mode may be triggered by a loss of echo, a bad configuration, or certain device
faults. You can select can select one of three possible values to be reported when a
Failsafe mode occurs:
• Default value (Failsafe value) used as output value.
• Store last valid output value.
• Calculated output value is incorrect.
Failsafe value
Failsafe value is a user-defined value. This allows you to enter the safest output value for
your application.
For example, you may want to select a user-defined high value, to prevent an overfill
(Failsafe Hi). Or you may want to select a low value, to protect a pump from operating dry
(Failsafe Lo).
False Echoes
False echoes can appear during the receive cycle. They are often created by internal
impediments like a ladder rung, and are usually indicated by an incorrect high level
reading.
Near Range (Blanking)
Near Range allows you to set a distance in front of the antenna, within which any echoes
will be ignored. But Auto False-Echo Suppression is generally recommended in
preference to using Near Range.
Auto False-Echo Suppression
The TVT adjustment parameters allow you to set a TVT (Time Varying Threshold) curve, so
that SITRANS LR 460 will ignore false echoes.
The default TVT curve 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 curve. You can use Auto False-Echo Suppression
to filter it out. If possible, rotate the instrument before using Auto False-Echo
Suppression, to lower the amplitude of false echoes.
Page 85 SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01
mmmmm
F: Technical Reference
When you set Auto False-Echo Suppression to Learn, the instrument learns the echo
profile at that moment1. Then it uses the learned profile instead of the default TVT curve,
for the distance set in Auto False Echo Suppression Distance. The learned profile
(learned TVT curve) follows the echo profile, so that no large false echoes rise above the
learned TVT curve. From the end of the Auto False-Echo Suppression Distance, the
default TVT curve is used. The material level echo rises above this, and is selected as the
true echo.
See page 69 for examples of the echo profile before and after using Auto False-Echo
Suppression.
1. Set Auto False-Echo Suppression to Learn when the material level is substantially lower than
process full level (ideally when the tank is empty or almost empty).
