General Information
SITRANS LR 400
The SITRANS LR 400 is a long-range FMCW radar level instrument. A liquids version (L) is
available for use in liquids storage, performing well on low dielectric liquids or sticky
materials requiring a purging unit. A solids version (S) incorporates the Easy Aimer design
for use in solids, especially conditions of extreme dust. On both versions, the narrow
antenna beam results in a sharp radiation cone, which makes the SITRANS LR 400 quite
insensitive to vessel interferences.

General Information
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 end of the antenna must reach inside the vessel through the vessel nozzle (see
page 19).
If the device is rotated, return the orientation of the housing to its previous position with
reference to the flange, to ensure similar performance.

**An optional purging system can be installed between the flange and the horn antenna.
The system provides a 1/8” NPT inlet on the flange where cooling air or cleaning fluid
passes through the universal flange and exits the inside of the horn to clean it. The
customer will supply the purging medium by manual or automatic valve system. This
option is only available with universal flanges.

Purging System
For more frequent cleaning, a purging system can be installed between the flange and the
horn antenna. The system provides an inlet on the flange where cooling air or cleaing fluid
passes through the flange and exits the inside of the horn to clean it. The customer will
supply the purging medium by manual or automatic valve system. This option is only
available with universal flanges on the Liquids version of the SITRANS LR 400.

Operation
Operation
General Information
You can operate the SITRANS LR 400 with:
• Hand-held infrared programmer
• HART Communicator or PROFIBUS PA
• PC/Laptop and SIMATIC PDM software (recommended)
Measuring Principle
The SITRANS LR 400 operates according to the FMCW (Frequency Modulated Continuous
Wave) method. Its antenna sends microwaves to the surface of the measuring medium.
The wave frequency is modulated continuously (see Determining the Differential
Frequency on page 25). A receiver registers the reflection at the surface of the measuring
medium and links it with the simultaneously radiated signal.
The propagation speed of microwaves in gases corresponds to the speed of light. The
distance d is proportional to the propagation time t:
d= distance, t = measured time, c = speed of light
Notes:
• The SITRANS LR 400 can be operated and programmed most comfortably
with the SIMATIC PDM software. This software gives you the added
possibility of saving and archiving your application-specific parameters and
copying them back into the device if necessary.
• It is best to perform the operations described in the following sections
directly on the device to familiarize yourself with the operation.

Operation
As the transmission signal has changed its frequency until the reception signal arrives, the
linked signal gives a differential frequency fd, which is proportional to the distance d from
the reflecting surface.
The distance d is given by the ratio of the differential frequency fd to the frequency
deviation B and the duration of a frequency modulation phase T :
B = bandwidth (frequency deviation), d = distance, T = modulation duration,
c = speed of light
Determining the Differential Frequency
Example
The linear frequency deviation is 200 MHz at a modulation duration of 10 ms. The surface
of the measuring medium is 10 m away from the transmitting antenna. The difference
signal then has a frequency of:
Every reflection at a surface generates a different frequency. The reception signal
therefore consists of a frequency mix from which the disturbance frequencies must be
filtered. These can be caused by fixed targets like struts inside the vessel.

Operation
Operating the SITRANS LR 400
Use the arrow keys at the bottom of the hand programmer to program the SITRANS
LR 400. The two-line LCD displays the parameters. You can alter the setting or change to
other parameters using the arrows on the hand programmer (see page 27 for information
on navigating the menus using the arrow keys).
Hand Programmer
Selecting a Parameter
After a successful self-test, the SITRANS LR 400 displays the two-line multi-display.
Press LEFT ARROW to access the parameter menus. The first line of the display tells
you the current parameter menu level. The second line shows one of the parameters you
can access in the current parameter group. Scroll through the parameters in the group by
touching UP and DOWN . RIGHT accesses the parameter displayed on the
second line. LEFT closes this parameter and moves up one level until you return to the
multi-display.
When you select a parameter, its current value is displayed in the second line. When the
value flashes, programming is enabled, (see Disabling and Enabling Programming on
page 29) and you can change the current setting. If the parameter value cannot be
changed or if programming is disabled, the value will not flash.
Note: The ARROW buttons shown below are required for programming
this product. The additional buttons on the hand programmer do not
apply to the SITRANS LR 400.

Operation
Structure of Parameters
Operation is hierarchically structured: the parameters are arranged in groups and
assigned a numerical menu identification (see example below).
Changing a Parameter Value
Selecting a Parameter Value from a List
In many cases, you can assign a parameter a value from a list of options.
You will see a single item of the selection list in the second line of the display.
• Press UP or DOWN to cycle through the list and choose the desired entry.
Press RIGHT to assign the current entry to the parameter. The device accepts
the new setting, closes the input and returns to the next parameter level up.
• LEFT operates like a CANCEL key: When pressed, the device closes the
parameter input but keeps the originally displayed value. It does not save a changed
setting!
For an example of assigning a value from a selection list, see Operating Examples on
page 30.

Operation
Entering a Parameter Value
The ARROW keys operate like a cursor control when entering a parameter value with the
input position marked by flashing of a single character.
• Increase or decrease a character’s value by using UP and DOWN .
• Press RIGHT to move the input position to the right. At the far right position,
press RIGHT again: operates like an ENTER key. The device saves the
changed value and closes the parameter unless the value is not within the
permissible input range. Then an error message is displayed.
• Press LEFT to move the input position to the left. At the farthest left position,
press LEFT again: it now functions as a CANCEL key. The device closes the
parameter input without saving the changed value.
Top or bottom of representable range
If you press UP when the value is at the top of the representable range,
SITRANS LR 400 automatically places the value at the next highest position. If 0.9 is
displayed and you press UP , the value becomes 1.0. So, 9 becomes 10, 90 or 99
become 100 (depending on whether you have set the input position to the second or first
9), etc.
This input system also works in the opposite direction: For example, when 100 is
displayed and you press DOWN on the first or second 0, the numeric value changes
to 90 or 99 and the device cancels the places in front of the decimal point.
Decimal point
You can also set the cursor to the decimal point (unless an integer value is currently
displayed). UP or DOWN then multiply or divide the displayed value by 10. The
necessary additional places in front of the decimal point appear. You cannot change the
number of displayed decimal places.
Display scrolling
Display text assigned to a parameter may sometimes be longer than the field of the
display. An arrow pointing outward on the right or left hand side of the display line
indicates that the text continues outside the display. You can move the text with
RIGHT and LEFT by moving the pointer past the end of the line, to allow you to
read the rest of the text.
See Operating Examples on page 30 for an example of manual input.

Operation
Disabling and Enabling Programming
To prevent unauthorized personnel causing programming errors through the display
module, set a customer code – a personal, freely selectable code number up to 9 digits. A
device protected by a customer code still displays all functions and values but it requests
input of the code number before allowing a parameter to be reset.
Programming is enabled when you:
• enter the requested customer code for the current parameter. (Only the current
parameter is enabled for reprogramming. All the others are still waiting for input of
the customer code.)
or
• release the programming lock for all parameters at once using the Code Input
Parameter (see Parameter 5.1 on page 62).
The programming lock will be released for approximately 10 minutes.
When you return to the multi-display or enter a number in the Code Input parameter
which is different from the customer code, or do not operate the device for 10 minutes,
the programming lock is enabled.
Note: The customer code is activated 10 minutes after you have programmed
Parameter 5.2 Customer Code.
Note: If Customer Code (Parameter 5.2) is 0, programming of parameters is always
enabled. We strongly recommend that a customer code be entered after all
programming is completed to secure the programmed values from change.

Parameters (HART)
4.2.2.3: Dead band (F = 0.4 m)
Area below the flange in which measured values are ignored
Specification of a dead band in the units system selected according to Parameter 4.1.5
defines a minimum distance from the flange which the measuring medium must have for
the device to accept the measured values as valid. This suppresses reflective
interference generated by the nozzle, close obstacles, or the antenna.
For solids applications, a dead band setting of 1 m minimum is recommended
4.2.2.4: Correction Factor (F = 1.0)
Correction factor for physical measuring influences
The propagation time of the microwaves between the antenna and the measuring
medium changes slightly depending on the pressure inside the vessel. If this pressure is
constant, however, it can be included in the evaluation according to the equation:
K = correction factor, p = pressure inside the vessel in bar, Tgas = gas temperature in °C,
εr, G as = dielectric of the overlying gas, e.g. ερ, air = 1.00059
Enter the correction factor K as a dimensionless value.
4.2.2.5: Filling Speed (F = 200 mm/min)
Typical speed of change of the level. Not displayed if user vessel is selected in Parameter
4.2.2.1 (Application Type).
This parameter is not displayed when a user vessel is selected in Parameter 4.2.2.1. When
you determine that the displayed measured value does not follow the change in the
height of the level in the vessel, you can enter a value for the speed with which it
generally changes. This assigns a greater probability to measuring targets which move at
this speed.

Parameters (HART)
If the display does not follow the level height continuously but in abrupt jumps, you should
choose a higher filling speed. If multiple echoes are indicated during filling/emptying a
vessel, select a lower filling speed. In the case of very low filling speeds (a few mm/min)
switch off Parameter 4.2.3.3. If different filling/emptying speeds occur, select the higher
speed.
4.2.2.6: Reflectivity (for qualified personnel only)

The failsafe timer begins when there is a loss of echo condition. This loss of echo
condition will occur when there is no signal available above the Auto False Echo
Suppression threshold as defined in Parameter 4.2.3.9.
4.2.2.9: Range Extension (F = 3 m)

4.2.3.1: Sensor Damping (F = 1 s)
Averaging of measuring signal. Not displayed if a user vessel is selected in Parameter
4.2.2.1 (Application Type).
Enter the damping in seconds.
This parameter is not displayed when a user vessel is selected in Parameter 4.2.2.1
(Application Type). The sensor damping influences the evaluation of the measuring
signal. If the level generally only changes slowly and continuously, a time constant set
here can improve the measuring accuracy and the validity in poorly reflecting measuring
media or those with a restless surface. The sensor damping must always be smaller than
the interval of the time of change of the level (e.g. 1 mm/10 s), because too high a value
would have a negative influence on the measuring result.
4.2.3.2: Multiple Echo (F = on)
Evaluate multiple echo
The multiple echo evaluation suppresses multiple reflections by assigning them a lower
probability than the measuring signal.
4.2.3.3: Echo Motion (F = off)
Evaluate echo motion
Dynamic processes in the vessel are included in the evaluation of the measuring targets.
The typical filling speed can be set in Parameter 4.2.2.5. If the measured value still does
not follow the level height, switching off echo motion may improve the result.
Value numerical
Note: Specification of damping directly influences the evaluation of the measuring
signal. If you only want to dampen the calculated outputs at the analog output, you

Parameters (HART)
4.2.5.8: Calibrate/table
If your vessel deviates from the forms offered, the necessary data is not available or is
unknown, or you need a vessel characteristic with greater accuracy, you will need to use
a level/volume calibration table. You can enter reference values from a table provided by
the vessel manufacturer or do the calibration manually and enter the determined
reference values.
You can only enter pairs of values consisting of level and volume.
The 4.2.5.8 Calibrate/table parameter offers the following selection possibilities:
4.2.5.8.1: Calibrate
Here you can enter up to 50 reference values whose levels SITRANS LR 400 measures.
Enter the appropriate volume (determined by manual calibration).
If you access this parameter, first the currently measured level is displayed. Accept it by
pressing LEFT . Enter the appropriate volume: save it by pressing RIGHT or reject it
by pressing LEFT .
Then the device displays Calibrate. Access again by pressing RIGHT to select a
further reference value. The device automatically offers you the next undefined reference
value.
We recommend entering a maximum of two or three reference values for the linear range
of the vessel and to use the others for the non-linear portion.
If you enter a second volume value for the same level, the reference value saved earlier is
overwritten.
4.2.5.8.2: Enter table
Manual entry of a table
Here you can enter up to 50 reference values provided by the vessel manufacturer in any

parameter are listed below. For the values associated with Parameter 4.2.5.8:
Calculate, go to page 51.
Note: Entering the vessel characteristic with the hand programmer can be a time-
consuming procedure. It can be done more quickly and comfortably with the SIMATIC

conditionally possible with the hand programmer.

(Enter level) and the volume corresponding to the level (Enter volume).
The device then displays Enter table again. Access again to enter a further reference
value. The device automatically offers you the next undefined reference value.
We recommend entering a maximum of two or three reference values for the linear range

4.2.5.8: Calculate
Automatic calculation of a vessel characteristic is faster than manual entry by calibrating
or a table. However, the calculated vessel characteristic is not as accurate as a manually
calibrated characteristic – especially in the non-linear sections of the vessel when errors
of ≤ 1 % may occur. As well, the necessary data which you can get from the design
documents of your vessel must still correspond to the real conditions.

Parameters (HART)
Current limiting
The URV is always at 20 mA. If you set the current limit to a higher value, you can have the
measured values output outside the measuring range (up to approx. 115%).
4.3.5: Error Signal (F = 3.6 mA)
Current value of the error signal
In the event of a fault the device applies the current defined here to the analog output.
You can choose between 3.6 mA, 22 mA, 24 mA, Hold 10 s, Hold 1 min, Hold 2 min, Hold 3
min and Hold continuously.
When the Hold... values are selected, the device outputs the last valid value until the set
time has run out or the fault has been eliminated. If the fault persists after the set time
runs out, the analog output switches to an error signal of 3.6 mA.

4.4.1: Function DO (F = Alarm)
Assignment of the digital output
Here you can select whether the digital output supplies the upper or lower limit value of
level or volume or an alarm (device error, measurement error; see Parameter 3.1) to the
control system. If you select the No function option, the digital output is switched off.
Selection of a limit value enables Parameter 4.4.4. If you select Alarm or No function in
this parameter, Parameter 4.4.4 will not be visible.
4.4.2: Error Level (F = D: Error Signal)

5. Options
5.1: Enter Code
Input of customer code to enable programmability
The device compares a code number which you enter here with the code defined in
Parameter 5.2. If your entry matches the customer code completely, it releases the
programming lock for all parameters. Any other code number locks and disables
programming.
5.2: Customer Code (F = 0)
Determination of customer code
Here you define the customer code (up to nine digits), with which you can protect the
device parameters against programming errors. It is strongly recommended that a
customer code be entered after all programming is completed to secure the programmed
values from changes.
Use of the customer code is explained in Disabling and Enabling Programming on page
29.

Troubleshooting
Troubleshooting
The SITRANS LR 400 is factory-tested. Carefully selected components and compliance
with prescribed quality standards guarantee the high reliability of the SITRANS LR 400.
Please review the instructions below for troubleshooting before contacting the
responsible customer services.
Classification of Faults
Faults occurring in the SITRANS LR 400 can be classified in the following groups:
• faults caused by ambient influences: over- and under-temperature, moisture,
contamination by the measuring medium and other substances, mains faults,
vibration
• faults in the device: display, electronics, mechanics, connections
Please try to determine the fault and localize it as accurately as possible.
If the fault cannot be eliminated with the measures described below, follow the
instructions in Maintenance on page 78.
Self-test
If you get fault messages after the self-test, please proceed according to Fault Messages
on page 76.
If there is a malfunction in the device, you can also activate the self-test manually with
Parameter 3.2.1.
Symptoms, Causes and Their Remedy
Note: The device performs a self-test every time it is switched on. It is ready for
operation when the LCD displays the multi-display.
Symptom Possible causes Remedy
No display on the LCD Defective or missing
power supply
Check that the power supply is connected
correctly.
LCD is defective
Connect a HART Communicator or a PC/Laptop
with SIMATIC PDM software. If the device can be
parameterized from there, the LCD is defective.
Electronics are
defective
Measure the analog current output. If the output
current is not between 3.6 mA < x < 22 mA, the
electronics are defective. Replace the electronics
unit as described in Maintenance on page 78.
A fault message is
displayed Internal fault Call the fault display in Function 3.1.

Fault Messages
The device indicates faults with a flashing letter on the right of the first line of the display.
It has the following meaning:
• W: Warning – device is still ready for operation but faults may occur
• F: Fault – sporadic fault, device conditionally ready for operation
• D: Continuous fault – device is not ready for operation
Under Parameter 3.1.x, you will find a fault log which indicates the type of the fault(s) that
occurred. It indicates the device function status in which the fault occurred and outputs a
fault message in plain text.
An incorrect

Cleaning the Antenna
If the antenna is contaminated, any built-up material can be removed using air or soft
brushes. Be careful not to damage the PTFE emitter cone inside the antenna.
An optional purge kit is available from Siemens Milltronics if required. Contact your local
Siemens Millltronics representative for more details.
Solids Version
If the measured material is prone to build-
up, you may need to clean the antenna at
regular intervals to remove buildup that
may affect the measuring result. To
access the antenna, the flange must be
removed.
1. Disconnect the electronics by
turning off the connector waveguide,
located directly above the Easy
Aimer ball.
2. Remove the flange bolts. (position
label)
3. Lift off the process section (including
antenna).
4. Remove four Hex head M5 screws
holding the antenna. (position label)

WARNINGS:
• 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.
• 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.
• Never attempt to loosen, remove, or disassemble process connection or

HART Communications for the SITRANS LR 400
Highway Addressable Remote Transducer, HART, is an industrial protocol that rides on
top of a 4-20 mA signal. It is an open standard, and full details about HART can be
obtained from the HART Communication Foundation www.hartcomm.org
The SITRANS LR 400 can be configured over the HART network using either the HART
Communicator 275 by Fisher-Rosemount, or a software package. There are a number of
different software packages available, and the SITRANS LR 400 should work well with
any of them. The recommended software package is the SIMATIC® Process Device
Manager (PDM) by Siemens.
HART Device Descriptor (DD)
In order to configure a HART device, the configurator must have the HART Device
Descriptor for the unit in question. HART DDs are controlled by the HART
Communications Foundation. The HART DD for the SITRANS LR 400 is available on the
SITRANS LR 400 page of our website at www.siemens.com/milltronics.
Older versions of the library will have to be updated in order to use all the features in the
SITRANS LR 400. If you do not see SITRANS LR 400 under Siemens Milltronics using the
configurator, you will need to download an update file from our website:
www.siemens.com/milltronics
SIMATIC Process Device Manager (PDM):
This software package is designed to permit easy configuration, monitoring and
troubleshooting of HART and PROFIBUS PA devices. The HART DD for the SITRANS
LR 400 was written with SIMATIC PDM in mind and has been extensively tested with this
software. The HART DD for the SITRANS LR 400 is available on the SITRANS LR 400 page
of our website at www.siemens.com/milltronics.

PROFIBUS PA Communications for the SITRANS
LR 400
PROFIBUS PA is an open industrial protocol. Full details about PROFIBUS PA can be
obtained from PROFIBUS International at www.profibus.com
The SITRANS LR 400 is a Class A, Profile Version 3.0, PA device. It supports Class 1
Master for Cyclic data exchange, and Class 2 for acyclic services: (See below for details).
The SITRANS LR 400 can be configured using a software package. There are a number of
different software packages available and the SITRANS LR 400 should work well with
any one of them. The recommended software package is the Simatic Process Device
Manager (PDM) by Siemens.
Device Descriptor
In order to use Process Device Manager (PDM) with PROFIBUS PA, you will need the
Device Descriptor, which will be included with new versions of PDM. Currently you can
locate the Device Descriptor in Device Catalog, under Level/Echo/Siemens Milltronics.
If you do not see SITRANS LR 400 under Siemens Milltronics, you will need to download
an update file from the SITRANS LR 400 product page on our website:
www.siemens.com/milltronics
The GSD file
The GSD file SM_062A.GSD can be obtained from Siemens Milltronics at our web site:
www.siemens.com/milltronics. (There is an example on page 102, To configure and use
PROFIBUS PA with an S7-300 PLC.)
Bus address (Device Address)
• This value can be set via Bus Address in the Auto-setup parameters, or over the
network. (After changing the value, turn the unit off and back on again in order for
the change to take effect.)
Values Range: 0 to 126
Pre-set: 126
Page 99 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04

Appendix VI
Power Demands
The maximum number of devices that can be connected to a bus line depends on their
current consumption and the respective application conditions. When operating in an
area where there is no risk of explosion, the couplers/links can feed up to 400 mA into the
bus.
When operating in explosion risk areas, the intrinsic safety is only guaranteed when the
maximum power fed into the bus does not exceed certain voltage and current values.
These are normally:
Current IS < 128 mA, voltage U0 < 15 V
The number of devices which can be connected to a bus line is determined by finding
the combined maximum current consumption of all the connected devices (10.5 mA for
the SITRANS LR 400). Plan to 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 and output 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
When you configure the SITRANS LR 400 on the PROFIBUS PA bus, there are two slots
available for modules.
Slot 0 always transmits Level information and slot 1always Volume information. Slot2 is
always Mass information. If you do not wish to have data transmitted, then you must use
a Free Place module in that slot.
When you select a module, for the three values, there are two alternatives: a normal
version and a short version, for example, Level (short) and Level. The difference between
the two is the way each one identifies the function block used. Level uses both the
identifier and the extended identifier byte to determine which function block in the unit to
use. Level (short) uses only the identifier byte. In the current release of PROFIBUS PA
there is no functional difference between the short and normal versions. However, the
longer identifier is the preferred way to identify the function block and you should select
the normal version in each case.
Note: Each of the slots has to have a module defined in it.
WARNING: Only certified supply units (DP/PA couplers or DP/PA
links) may be used to feed the intrinsically safe PROFIBUS. See
the EC Type Examination Certificate for requirements.
7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 100
mmmmm
Appendix VI
The 3 function blocks (Level, Volume, Mass) 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 default setting for the variable level is meters.
The default setting for the variable volume is m3. The default setting for the variable mass
is kg. You can change the settings of the variables by changing the settings of the
function block. This is typically done using PDM.
The 5th byte is the status word and the list of possible values is given in the chart on
page 101.
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.
If you select a Free Place module to fill one of the slots, this will affect the byte number.
