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. The additional buttons on the hand programmer do not apply to the SITRANS LR 400.Key Programming ModeParameter scroll UPParameter scroll DOWNLEFT Arrow (or CANCEL)RIGHT Arrow (or Enter)Note: The background illumination of the LCD switches on as soon as you use a button.

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 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.

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

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 92mmmmmAppendix VAppendix VHART Communications for the SITRANS LR 400Highway 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.orgThe 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/milltronicsSIMATIC 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.
