7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 3mmmmmGeneral InformationSITRANS LR 400The 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.

Page 18 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04mmmmmInstallationInstallationMounting Location• Do not mount in direct sunlight without the use of a sun shield. Refer to Appendix III (Ambient/Operating Temperature Specification) on page 88.• Mount the unit more than 1 m away from the vessel walls, pipes and other assemblies as well as the filling stream, because all these influences will become noticeable as reflective interference. Align the antenna so that the radar cone intersects the surface of the measuring medium as vertically as possible Notes:• The SITRANS LR 400 is rated for Type 4X/NEMA 4X, Type 6/NEMA 6, IP67. Follow all installation and operating instructions to meet the requirements of this type of protection. Use only approved, suitable sized hubs for watertight applications.• Observe all maximum permissible ambient and process temperatures. Refer to Appendix III (Ambient/Operating Temperature Specification).Provide a warning sign and/or touch guard if the surface of the measuring instrument can become hotter than 70 °C in use.WARNINGS: • This product is designated as a Pressure Accessory per directive 97/23/EC and is not intended for use as a safety device.• Improper installation may result in loss of process pressure.WARNING: For vessels with conical or parabolic tops, avoid mounting the unit at the center.

7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 24mmmmmOperationOperationGeneral InformationYou can operate the SITRANS LR 400 with:• Hand-held infrared programmer• HART Communicator or PROFIBUS PA• PC/Laptop and SIMATIC PDM software (recommended)Measuring PrincipleThe 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.SITRAN S LR 400ddct⋅2--------=
Page 25 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04mmmmmOperationAs 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 FrequencyExampleThe 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.fd2Bd⋅⋅Tc⋅------------------ d,fdTc⋅⋅2B-------------------==frequencyBfdtTtimetransmission signalreception signalfd2210810⋅⋅ ⋅10 3– 3108⋅⋅----------------------------------13 333kHz,==
7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 26mmmmmOperationOperating the SITRANS LR 400Use 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 ProgrammerSelecting a ParameterAfter 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.

Page 27 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04mmmmmOperationStructure of ParametersOperation is hierarchically structured: the parameters are arranged in groups and assigned a numerical menu identification (see example below).Changing a Parameter ValueSelecting a Parameter Value from a ListIn 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.Operating level 1Operating level 2Operating level 3Function group2 DisplayFunction group3 DiagnosticsFunction group4 Device data2.

7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 28mmmmmOperationEntering a Parameter ValueThe 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 rangeIf 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 pointYou 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 scrollingDisplay 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.
Page 29 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04mmmmmOperationDisabling and Enabling ProgrammingTo 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.

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 = 1.00059Enter 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.Value numerical value, Minimum value = Length of the antennaNote: The dead band should exceed the antenna’s length.Value numerical valueValue numerical valueK11εrGas,1–()+273 p⋅TGas 273+--------------------------⋅-------------------------------------------------------------------------=
7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 44mmmmmParameters (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)This parameter is for Factory Authorized Personnel Only.4.2.2.7: Failsafe Level (F = Hold Continuously)Selects the default measurement in the event that the failsafe timer expires4.2.2.8: Failsafe Timer (F = 10 min)Sets the time delay, in minutes, before entering failsafe levelThe 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)Sets the amount of range extension as measured from the tank height and extending beyond the measurement range. For vessels with conical or parabolic bottoms, you may need to increase this value to ensure an empty vessel reads empty.4.2.3: Sensor ParameterHere you can view and change the sensor parameters which you have selected according to Parameter 4.2.2 (Measuring Conditions).Value100 %0 %Hold ContinuouslyValue 1 min2 min, etc.Value numericalNote: The factory settings for the user vessels are not editable.
Page 45 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04mmmmmParameters (HART)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 echoThe 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 motionDynamic 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 numericalNote: 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 should set the damping of level, volume or mass described in Function 4.2.4.4 (MinLim Level).Value OnOffValue OnOff

The window size is calculated from the set filling speed. Switch off window tracking for applications where the SITRANS LR 400 is unable to keep up to level changes. By using SIMATIC PDM, you can display a list of all echoes in your vessel. It provides the distance between the flange and the measuring medium’s surface, as well as the distances of fixed targets. These may be directly used and transferred to the fix distance list.4.2.3.5: Tank Empty Detect (for qualified personnel only)This parameter is for Factory Authorized Personnel Only.4.2.3.6: Auto Fix Distance (for qualified personnel only)This parameter is for Factory Authorized Personnel Only.4.2.3.7: Fix Distance List (for qualified personnel only)This parameter is for Factory Authorized Personnel Only.4.2.3.7.1 to 4.2.3.7.9: Fix Distance Values (for qualified personnel only)These parameters are for Factory Authorized Personnel Only4.2.3.8: Auto False Echo Suppression (F = Use)Learns and records the current signal up to the suppression distance setting.

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: CalibrateHere 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 tableManual entry of a tableHere you can enter up to 50 reference values provided by the vessel manufacturer in any order. Note: Select the option Calibrate/table or Calculate as required. The selection controls the display of Parameter 4.2.5.8. The possibilities of each 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 PDM software. There, an entered table can be edited simply – an option which is only conditionally possible with the hand programmer.Value numerical value

Enter the level as a distance from the floor of the vessel in the units selected according to Parameter 4.1.1 (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 of the vessel. Use the other reference values for the non-linear section.If you enter a second volume value for the same level, the reference value saved earlier is overwritten.4.2.5.8.3: Show tableDisplay tableHere you can display the entered reference values sorted on levels. In the second line, the level corresponding to the first reference value appears first and then the corresponding volume value when you switch further. Each switching accesses a further reference value.4.2.5.8.4: Clear tableDelete tableIf you choose all in this parameter, the entire saved table is deleted. You can delete individual reference values with the selection 1st, 2nd etc. that were displayed in Parameter 4.2.5.8.3.or4.2.5.8: CalculateAutomatic 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.The 4.2.5.8: Calculate parameter requires the following parameters:Value selectionValue selectionNote: The reference values are sorted in order of filling states and do not necessarily correspond to the order of the value pairs you have entered.

7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 98mmmmmAppendix VIAppendix VIPROFIBUS PA Communications for the SITRANS LR 400PROFIBUS PA is an open industrial protocol. Full details about PROFIBUS PA can be obtained from PROFIBUS International at www.profibus.comThe 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 DescriptorIn 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/milltronicsThe GSD fileThe 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 126Pre-set: 126
Page 99 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04mmmmmAppendix VIPower DemandsThe 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 VThe 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 DataWhen 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 DataWhen 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 100mmmmmAppendix VIThe 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.
