It is particularly suitablefor level measurement in water treatment, in pump stations as well asstorm water overflow tanks, for flow measurement in open flumes andfor gauge measurement.The antenna of the radar sensor emits short radar pulses with aduration of approx. 1 ns. These pulses are reflected by the productand received by the antenna as echoes. The transit time of the radarpulses from emission to reception is proportional to the distance andhence to the level. The determined level is converted into an appropriateoutput signal and outputted as measured value.3.3 Packaging, transport and storageYour instrument was protected by packaging during transport. Itscapacity to handle normal loads during transport is assured by a testaccording to DIN EN 24180.The packaging of standard instruments consists of environmentfriendly,recyclable cardboard. For special versions, PE foam or PEfoil is also used. Dispose of the packaging material via specialisedrecycling companies.Transport must be carried out under consideration of the notes on thetransport packaging. Nonobservance of these instructions can causedamage to the device.The delivery must be checked for completeness and possible transitdamage immediately at receipt. Ascertained transit damage or concealeddefects must be appropriately dealt with.38061-EN-121011StorageVEGAPULS WL 61 • 4 … 20 mA/HART - two-wireUp to the time of installation, the packages must be left closed andstored according to the orientation and storage markings on theoutside.Unless otherwise indicated, the packages must be stored only underthe following conditions:Not in the open• Dry and dust freeNot exposed to corrosive media• Protected against solar radiation• Avoiding mechanical shock and vibration11

These includeabove all the process pressure, process temperature as well as thechemical properties of the medium.You can find the specifications in chapter "Technical data" and on thetype label.4.2 Mounting versionsMost simply mount the instrument via the straining clamp. For thispurpose, the connection cable is provided with a strain relief wire ofKevlar.In order to avoid faulty measured values, make sure that the sensordoes not oscillate.> 200 mm(7.87")Fig. 5: Mounting via a straining clampMounting bracketFor a rigid mounting, a mounting bracket with opening for threadG1½, e.g. from the VEGA product range, is recommended. Themounting of the sensor in the bracket is carried out via a G1½ counternut of plastic. Take note of chapter "Mounting instructions" for thedistance to the wall.38061-EN-121011VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire13

4 Mounting> 200 mm(7.87")Fig. 6: Mounting via a mounting bracketMounting strapThe optional mounting strap enables sensor mounting on e.g. a ceiling,wall or bracket. It is available in the following versions:• Length 300 mm for ceiling mounting• Length 170 mm for wall mountingThe instrument is normally mounted vertically on the ceiling.This ensures swivelling of the sensor up to 180° for optimum orientation.Fig. 7: Vertical mounting on the ceiling via the mounting strap with length300 mmAs an alternative, mounting can be carried out vertically on the wall.14VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire38061-EN-121011

4 Mounting> 200 mm(7.87")Fig. 8: Vertical mounting on the wall via the mounting strap with length 170 mmSome measuring points have only very little space between ceilingand water surface. In such cases, for example in closed stormoverflow basins, horizontal mounting of the sensor is recommended.The radar impulses must be directed via a 45° reflector - for examplea stainless steel sheet - to the water surface.45°> 50 mm(1.97")Fig. 9: Horizontal mounting with a mounting strap of length 170 mm with reflectorprovided by the customerInformation:With this mounting arrangement, the reference plane mentioned inchapter "Technical data" no longer applies. There is an offset thatmust be taken into account for the adjustment. Note the distancemeasured at min. level with the reflector, for example 2.5 m. Enterthis value as min. adjustment/measuring range begin. Determine thedifference between the min. and max. level, for example 1 m. The distancefor the max. adjustment results from 2.5 m - 1 m = 1.5 m. Enterthis value as max. adjustment/measuring range end.38061-EN-121011VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire15

As an alternative,the instrument can be already supplied with a tight, fix-mountedadapter flange from DN 100 (ASME 4" or JIS 100).You can find drawings of these mounting options in chapter "Dimensions".Fig. 11: Mounting by means of an adapter flange, for example, on a manhole lid.164.3 Mounting preparations, mounting strapThe optional mounting strap is supplied unassembled. It must bescrewed to the sensor before setup with the attached screws. Max.torque, see chapter "Technical data". Required tools: Allen wrenchsize 4.There are two different ways of screwing the strap to the sensor.Depending on the selected method, the sensor can be rotated inthe strap infinitely variable through 180° or in three steps 0°, 90° and180°.VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire38061-EN-121011

Use suitable flat seal, e.g. of EPDM with Shore hardness 25 or 502. Make sure the number of flange screws corresponds to the numberof flange holes3. Tighten all screws with the torque stated in the technical dataThe emitted radar impulses of the radar sensor are electromagneticwaves. The polarisation plane is the direction of the electrical wavecomponent. By turning the instrument in the connection flange ormounting strap, the polarisation can be used to reduce the effects offalse echoes.The position of the polarisation level is marked by marking bars on theinstrument.38061-EN-121011VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire17

4 Mounting1Fig. 14: Position of the polarisation level1 Marking barInstallation positionWhen mounting the sensor, keep a distance of at least 200 mm(7.874 in) to the vessel wall. If the sensor is installed in the center ofdished or round vessel tops, multiple echoes can arise. These can,however, be suppressed by an appropriate adjustment (see chapter"Setup").If you cannot keep this distance you should carry out a false echostorage before setup. This applies mainly if buildup on the vessel wallis expected. In this case, we recommend repeating a false echo storagelater with existing buildup.> 200 mm(7.87")Fig. 15: Mounting of the radar sensor on round vessel topsIn vessels with conical bottom it can be advantageous to mount thesensor in the center of the vessel, as measurement is then possibledown to the lowest point of the vessel bottom.18VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire38061-EN-121011

Make surethat you detect the product surface, not the inflowing product.Fig. 17: Mounting of the radar sensor with inflowing mediumSocketApproximate values of the socket heights are shown in the followingillustration. The socket end should be smooth and burr-free, if possiblealso rounded. After mounting, you have to carry out a false signalmemory during the parameter adjustment.38061-EN-121011VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire19

4 MountingFoam generationFlow measurement withrectangular flumeThrough the action of filling, stirring and other processes in the vessel,compact foams that considerably damp the emitted signals may formon the product surface.If foams are causing measurement errors, the biggest possible radarantennas, the electronics with increased sensitivity or low frequencyradar sensors (C band) should be used.As an alternative, sensors with guided microwave can be used. Theseare unaffected by foam generation and are best suited for such applications.The short examples give you introductory information on the flowmeasurement.

5 Connecting to power supply5 Connecting to power supplySafety instructionsVoltage supplyConnection cable5.1 Preparing the connectionAlways keep in mind the following safety instructions:•Connect only in the complete absence of line voltageIf overvoltage surges are expected, overvoltage arresters shouldbe installedPower supply and current signal are carried on the same two-wirecable. The voltage supply range can differ depending on the instrumentversion.The data for power supply are specified in chapter "Technical data".Provide a reliable separation between the supply circuit and themains circuits according to DIN VDE 0106 part 101.Keep in mind the following additional factors that influence the operatingvoltage:• Output voltage of the power supply unit can be lower under nominalload (with a sensor current of 20.5 mA or 22 mA in case of faultmessage)•Influence of additional instruments in the circuit (see load values inchapter "Technical data")The instrument is connected with standard two-wire cable withoutscreen. If electromagnetic interference is expected which is above thetest values of EN 61326-1 for industrial areas, screened cable shouldbe used.For instruments with housing and cable gland, use cable with roundcross-section. A cable outer diameter of 5 … 9 mm (0.2 … 0.35 in)ensures the seal effect of the cable gland. If you are using cable witha different diameter, exchange the seal or use a suitable cable gland.We generally recommend the use of screened cable for HART multidropmode.5.2 Wiring planWire assignment, connectioncable1238061-EN-121011VEGAPULS WL 61 • 4 … 20 mA/HART - two-wireFig. 23: Wire assignment fix-connected connection cable1 brown (+) and blue (-) to power supply or to the processing system2 Shielding5.3 Switch-on phaseAfter connecting the instrument to power supply or after a voltagerecurrence, the instrument carries out a self-check for approx. 30 s:23

7 Setup with PACTwareFig. 27: Example of a DTM viewAdjustmentSince a radar sensor is a distance measuring instrument, the distancefrom the sensor to the product surface is measured. For indication ofthe real level, an allocation of the measured distance to the percentageheight must be carried out. To perform the adjustment, enter thedistance with full and empty vessel, see the following example:0,5 m(19.68")100%25 m(196.85")30Fig. 28: Parameterization example1 Min. level = max. meas. distance2 Max. level = min. meas. distanceVEGAPULS WL 61 • 4 … 20 mA/HART - two-wire0%138061-EN-121011

7 Setup with PACTwareIf these values are not known, an adjustment with the distances of forexample 10 % and 90 % is possible. Starting point for these distancespecifications is always the seal surface of the thread or flange. Bymeans of these settings, the real level will be calculated.The real product level during this adjustment is not important, becausethe min./max. adjustment is always carried out without changingthe product level. These settings can be made ahead of timewithout the instrument having to be installed.Standard/Full versionAll device DTMs are available as a free-of-charge standard versionand as a full version that must be purchased. In the standard version,all functions for complete setup are already included. An assistant forsimple project configuration simplifies the adjustment considerably.Saving/printing the project as well as import/export functions are alsopart of the standard version.In the full version there is also an extended print function for completeproject documentation as well as a save function for measured valueand echo curves. In addition, there is a tank calculation program aswell as a multiviewer for display and analysis of the saved measuredvalue and echo curves.The standard version is available as a download under www.vega.com/downloads and "Software". The full version is available on CDfrom the agency serving you.7.3 Saving the parameter adjustment dataWe recommend documenting or saving the parameter adjustmentdata via PACTware.

The data remain even with voltage interruption.Measured value memoryEvent memoryUp to 60,000 measured values can be stored in the sensor in a ringmemory. Each entry contains date/time as well as the respectivemeasured value. Storable values are for example:• DistanceFilling heightPercentage value• Lin. percent• ScaledCurrent value• Meas. reliability• Electronics temperatureWhen the instrument is shipped, the measured value memory isactive and stores distance, measurement certainty and electronicstemperature every 3 minutes.The requested values and recording conditions are set via a PC withPACTware/DTM or the control system with EDD. Data are thus readout and also reset.Up to 500 events are automatically stored with a time stamp in thesensor (non-deletable). Each entry contains date/time, event type,event description and value. Event types are for example:Modification of a parameter• Switching on and off timesStatus messages (according to NE 107)• Error messages (according to NE 107)The data are read out via a PC with PACTware/DTM or the controlsystem with EDD.38061-EN-121011Echo curve memoryVEGAPULS WL 61 • 4 … 20 mA/HART - two-wireThe echo curves are stored with date and time and the correspondingecho data. The memory is divided into two sections:Echo curve of the setup: This is used as reference echo curve forthe measurement conditions during setup. Changes in the measurementconditions during operation or buildup on the sensor can thusbe recognized. The echo curve of the setup is stored via:• PC with PACTware/DTMControl system with EDD• Indicating and adjustment module33

9 Diagnosis, Asset Management and serviceFurther echo curves: Up to 10 echo curves can be stored in a ringbuffer in this memory section. Further echo curves are stored via:• PC with PACTware/DTM• Control system with EDD9.3 Asset Management functionThe instrument features self-monitoring and diagnostics accordingto NE 107 and VDI/VDE 2650. In addition to the status messages inthe following tables there are more detailed error messages availableunder the menu item "Diagnostics" via the indicating and adjustmentmodule, PACTware/DTM and EDD.Status messagesThe status messages are classified in the following categories:• FailureFunction checkOut of specification• Maintenance requirementand explained by pictographs:1 2 3Fig. 29: Pictograms of the status messages1 Failure - red2 Function check - orange3 Out of specification - yellow4 Maintenance - blue434Failure: Due to a malfunction in the instrument, a failure message isoutputted.This status message is always active. It cannot be deactivated by theuser.Function check: The instrument is in operation, the measured valueis temporarily invalid (for example during simulation).This status message is inactive by default. It can be activated by theuser via PACTware/DTM or EDD.Out of specification: The measured value is unstable because theinstrument specification is exceeded (e.g. electronics temperature).This status message is inactive by default. It can be activated by theuser via PACTware/DTM or EDD.Maintenance: Due to external influences, the instrument functionis limited. The measurement is affected, but the measured value isstill valid.
