1.1 Function

Radio detection and ranging: Radar.VEGAPULS radar sensors are used for con-tinuous and non-contact distance measure-ment. The measured distance corresponds toa filling height and is provided as level.

emission – reflection – receipt

Smallest 5,8 GHz radar signals are emittedfrom the antenna of the radar sensor as shortpulses. The radar impulses reflected by thesensor environment and the product are re-ceived by the antenna as radar echoes. Therunning period of the radar impulses fromemission to receipt is proportional to the dis-tance and hence to the level.

VEGAPULS radar sensors can reach this in aspecial procedure of the time transformationwhich spreads more than 3,6 million echopictures per second in a slow-motion picture,then freezes and evaluates them.

The radar pulses are emitted by the antennasystem as impulse packets with a pulse dura-tion of 1 ns and impulse breaks of 278 ns; thiscorresponds to a pulse package frequency of3,6 MHz. In the pulse breaks the antennasystem operates as receiver. Hence signalrunning periods of less than one millionth of asecond must be processed and the echopictures must be evaluated in a fraction of asecond.

Hence it is possible for the VEGAPULS radarsensors to evaluate the slow-motion pictures ofthe sensor environment precisely and in detailin cycles of 0,1 seconds without using verytime consuming frequency analysis necessaryfor other radar principles.

Virtually all products can be measured

Radar signals physically react similar to visiblelight. According to the quantum theory theypenetrate empty space. Hence they are notbound such as e.g. sound to a conductiveproduct (air) and spread like light with lightvelocity. The radar signals react to two electri-cal primary quantities:- the electrical conductivity of a substance.- the dielectric constant of a substance.

1.3 Adjustment

Each application is unique, hence each radarsensor requires some basic information onapplication and environment.

Operation and parameter adjustment on theradar sensors is carried out with- PC or- signal conditioning instrument.

Adjustment with PC

The set-up and adjustment of VEGAPULSradar sensors is generally made on the PCwith the adjustment program VVO (VEGAVisual Operating) under Windows®. The pro-gram is menu-guided by pictures, graphicsand process visualizations for quick operationand parameter adjustment.

Product description: Adjustment

On the sensor, on the branch of signal lines orin the process control system you will haveaccess to the sensors. The adjustment soft-ware allows a glance into each vessel.

The adjustment and parameter data can bestored on PC and transferred to other sensors.

The adjustment program VVO divides theadjustment in three stages:- operator (adjustment and indication of

measured values)- maintenance (parameter adjustment)- planning (service and system parameters).

The adjustment stages are protected by ac-cess hierarchies so that important parameteradjustments or service adjustments are sepa-rated from the standard adjustment. By usinga password, the adjustment values, param-eters and service adjustments are protectedagainst manipulation.

Sensor with digital signal output (VBUS), foradjustment the PC is either plugged to thetwo-wire signal line (e.g. on a terminal socket)or directly to the VEGALOG 571 Processingsystem or to the VEGAMET signal conditioninginstrument

Adjustment with signal conditioninginstrument

Beside the PC, sensors with digital transmis-sion of measured data (VBUS) can also bedirectly adjusted with the connected signalconditioning instrument.

In addition VEGAMET 514 V and 515 V signalconditioning instruments have and adjustmentmodule by which you can carry the parameteradjustment in text dialogue.


1.4 Antennas

The antenna is the eye of the radar sensors.The antenna shape does not lead to assumehow precise the geometrical form of an an-tenna must be adapted to the physical fea-tures of the electromagnetic fields. A shape,deciding on the sensitivity, similar to the sensi-tivity of a directional microphone.

Four antenna systems are available for differ-ent applications and process requirements.Each system is featured out beside the focus-ing characteristics by special chemical andphysical features.

Horn antenna

Horn antennas are best suitedfor most applications. Theyfocus the radar signals verywell. Manufactured out of1.4571 (stst), alloy C4, alloyC22 or Tantalum are very rug-ged and physically as well aschemically resistant. They aresuitable for pressures up to64 bar and with appropriate

cooling for product temperatures of more than1000°C.

Product description

Rod antenna

Rod antennas with high chemi-cal resistance require smallerflange diameters (DN 50). Theantenna rod and the wettedflange parts are completelymanufactured from PTFE sothat the rod antenna can beeasily cleaned and is henceinsensitive to condensation.The rod antenna is suitable forpressures up to 16 bar andtemperatures up to 200°C.

Pipe antenna

Pipe antennas on surge orbypass pipes only form acomplete antenna system inconjunction with a measuringpipe which can be also bent.Pipe antennas are best suitedfor products with strong prod-uct movements or productswith low dielectric constant.

The measuring pipe means aconductor for the radar sig-nals. The running period of theradar signals changes in the

pipe and depends on the pipe diameter. Theelectronics must be programmed against thepipe inner diameter so that the running periodcan be adapted.

Classification

Classification EEx i intrinsically safe

With classification “i“ (intrinsically safe) electri-cal circuits are produced which cannot ignitean explosive mixture or explosive substanceneither during operation or in case of failure.Hence it is ensured that the electrical energyused (short-circuit) is lower than the ignitionenergy required to ignite the substance.

In addition the capacitive and inductive en-ergy storage is restricted such that they can-not store sufficient energy to ignite an explo-sive mixture.

With the classification “e“ (increased safety)measures taken which avoid that a connected,non-intrinsically safe circuit can ignite an ex-plosive mixture or explosive substance.

Selected materials, increased contact andtrack distances as well as lowest componenttemperatures exclude sparks and heating.

Classification EEx d

With the classification “d“ (pressure tight en-capsulation) instruments are constructed suchthat even in case a mixture inside the instru-ment ignites, no ignition energy escape to theexplosive atmosphere.

Classification EEx e increased safety


Types and versions: Configuration of measuring systems

Measuring system with one VEGAPULS 64 sensor (compact instrument)

• Analogue, standardized 0 … 20 mA-current signal as signal output. For adjustment, a digitaladjustment signal is superimposed to the 0 … 20 mA-sensor signal.

• Adjustment and parameter adjustment via a PC and the adjustment program VVO. For adjust-ment the PC is connected via the adapter VEGACONNECT to the 0 … 20 mA-signal line.

• Optionally an external digital/analogue indication. The indication can be separated from thesensor up to 25 m.

• The max. permissible resistance (load) of the 0 … 20 mA-signal output is 500 Ω.

In case the input resistors of the processing systems connected to the 0 … 20 mA-signal outputare less than 100 Ω, a resistor of more than 100 Ω must be switched into the 0 ... 20 mA signalline for the adjustment period.

The digital adjustment signal is short-circuited or damped via too small input resistors so that thedigital communication with the PC would no more be ensured.

2.3 Configuration of measuring systems

A measuring system of sensors with a 0 … 20 mA signal output (compact instrument) consistsonly of one sensor. For sensors with digital signal output, the measuring system consists of onesensor and one VEGAMET signal conditioning instrument or the VEGALOG Processing system.

On this page and the following ones you will see measuring systems with sensors providing alevel proportional 0 ... 20 mA current (compact instruments) as output signal.

On the following pages you will see measuring systems with sensors delivering a digital signal aVEGAMET signal conditioning instrument or to the VEGALOG Processing system. Signal condi-tioning instrument or Processing system deliver with these sensors various level proportionaloutput signals such as 0 … 20 mA currents, 0 … 10 V voltage or switching signals (relay) .


Measuring system with one VEGAPULS 81 sensor (compact instru-ment type D or E)

• Analogue, standardized 0 … 20 mA-current signal as signal output. For adjustment, a digitaladjustment signal is superimposed to the 0 … 20 mA-signal output.

Measuring range

The reference pane for the measur-ing range of the radar sensors isalways the lower part of the sensor.The measuring range of both instru-ment series (VEGAPULS 64 andVEGAPULS 81) is generally0 … 20 m. Optionally sensors with ameasuring range of 0 … 35 m canbe supplied. For measurements insurge or bypass pipes (pipe an-tenna) the max. measuring distanceis reduced by appr. 20%. Pleasenote for measurements where theproducts are filled up to the sensorflange, that build-up on the antennacan cause faulty measurements.

Emission cone and false reflections

The radar signals are focused by the antennasystem. The signals leave the antenna, similarto a light beam of a headlight, in the form of acone. This emission cone depends on theantenna used.

Each object in this emission cone causes areflection of the radar signals. Especially dur-ing the first meters of the emission cones,pipes, struts etc. cause strong false reflec-tions. E.g. in a distance of 6 m the false signalof a pipe is 9 time more than in a distance of18 m.

The energy of the radar signal spreads in caseof interfering surfaces which are further awaythan a larger surface, so that reflected falsesignals are weaker and hence more uncriticalthan in the narrow range.


Note the sensor axis is directed vertically tothe product surface, avoid installations withinthe 100%-cone such as e.g. pipes and struts.

If possible provide a “clear view“ inside theemission cone to the product and avoid instal-lations in the first third of the emission cone.

Optimum measuring conditions are availablewhen the emission cone is free from installa-tions.

False reflection

Flat installations and struts cause large falsereflections. They reflect the radar signal withhigh energy density.

Mounting and installation: General installation instructions

Profiles with smooth interfering surfaces causelarge interfering signals

Round profiles diffusely spread the radarsignals

Cover flat profiles with scatting screens

Smoothed interfering surfaces have a diffusereflection of the radar signals and cause falsereflections with low energy density. Hence theyare more uncritical than reflections on flatsurfaces.

If flat installations in the range of the radarsignals cannot be avoided, it is recommendedto reflect the interfering signals with a scatter-ing screen. Due to this scattering the interfer-ing signals will be less energetic and diffuseso that they can be filtered by the sensor.



4.2 Measurement of liquids

Horn antenna

Horn antenna on DIN-socket pieceMost of the time the mounting of radar sensorsis made on very short DIN-socket pieces. Theinstrument flange is the reference pane for themeasuring range. The antenna should alwaysprotrude out of the flange pipe.

When the DIN-socket piece is longer, pleasenote that the horn antenna must protrude atleast 10 mm out of the socket.

When mounting on dished boiler or basketarch vessel ceilings also on the long socketside, the antenna has to protrude at least10 mm.

Do not mount the instrument on arched vesselceilings in the middle of the tank or close tothe outer wall of the vessel, but appr. 1/2 vesselradius from the middle or from the outer vesselwall. Arched tank ceilings act for the radarsignals like a paraboloidal reflector. If theradar sensor is placed in the “focus“ of aparabolic tank cover, the sensor receivesamplified false echoes. Note that the radarsensor is mounted outside the “focus”, henceparabolic amplified false echoes are avoided.

Horn antenna directly on the vessel ceilingDependent on the stability of the vessel (sen-sor weight), the flat mounting directly on thevessel ceiling would be a good and favourablesolution. The top side of the vessel is the refer-ence pane.

Rod antenna

Rod antenna on DIN-socket pieceThe PTFE (Teflon) rod antenna is especiallyused in aggressive products such as lyes andacids. Applications in the food processingindustry with aseptic vessels require reactionneutral measuring systems often with smallervessel openings. The teflon rod antenna is notonly reaction neutral but can be also mountedto very small vessel openings with 50 mmaccess.

For measurements of liquids with the Teflonrod antenna, the mounting is made on astraight DIN-socket piece. The socket howevermust not be longer than 150 mm (when usinga longer antenna, not longer than 250 mm).The rod antenna is available in flange sizes ofDN 50, DN 80, DN 100 and DN 150.

Rod antenna directly on vessel openingAlternatively to the socket mounting, the rodantenna can also mounted directly to thecircular vessel opening (holes).

Note that the mechanical load of the PTFE-rodantenna is restricted. If the antenna is sub-jected to lateral power, their will be danger ofdeformation or break.



Pipe antenna(surge or bypass pipe)

Pipe antennas are preferably used on vesselswith many installations such as e.g. calorifiers,heat exchangers or quick stirrers. The meas-urement of products with strong turbulences,and installations in the vessel do not causefalse reflections.

By focusing of the radar signal within themeasuring pipe, also products with smalldielectric constants (ε

r 1,5 … 3) can be meas-

ured.

The surge pipes which open at the bottommust reach the requested min. level as ameasurement is only possible in the pipe.

Note the upper required ventilation hole in thesurge pipe. These ventilation and surge holesmust be in one axis with the type plate(VEGAPULS 64) or the casting nose(VEGAPULS 81).

As an alternative to the surge pipe in the ves-sel, a pipe antenna outside the vessel is possi-ble as a bypass pipe.

Note that with the measurement in a pipe, themax. measuring range is slightly reduced (seeTechnical Data).



Adhesive productsWhen measuring adhesive products, the innerdiameter of the surge pipe must be larger. Forslightly adhesive products or products neutralto adhesions, a measuring pipe of 50 mm isgood and cheap. For adhesive products thesurge pipe must have a larger nominal width(e.g. 100 mm) so that build-up does not causeMeasuring errors. Surge pipe diameters of DN50 to DN 150 can be selected.

Inhomogeneous productsIf you want to measure inhomogeneous orlaminated products in a surge pipe, the surgepipe must be provided with holes, long holesor slots. These openings ensure that the liquidin the pipe is mixed and corresponds to therest of the vessel liquid.

The more inhomogeneous the measured prod-uct, the tighter the openings should be.

For reasons of the radar signal polarization theholes and slots must be positioned in two rowsdisplaced by 180°.

The mounting of the radar sensor is then suchthat the type plate of VEGAPULS 64 or thecasting nose of VEGAPULS 81 is in one axiswith the rows of holes.

Surge pipe with stop valveWhen using a stop valve in the surge pipe, it ispossible to carry out maintenance and servicework without opening the vessel (e.g. withliquid gas or toxic products).

Requirement for an interference free operationis a ball valve outlet corresponding to the pipediameter. The ball valve must not have anycoarse edges or throats in the outlet againstthe measuring pipe.

4.3 Measurement of solids

As with liquids, the instrument for solid vesselsis most of the time mounted on a short DIN-socket piece.

Differing from the liquid measurement forwhich the sensor must be in rectangular posi-tion and hence vertical to the product surface,the angle of repose must be considered forsolids. Optimum measurements are achievedeven when the sensor axis point is vertically tothe solid surface.

DIN-flange directed in the inclination angle onthe angle of repose of the solid

Alternatively to the inclined welded DIN-flangeyou can either use on a large DIN-flange aconical adapter with an adapter flange plate oryou use a flange pipe adapter. Please notethat due to the inclined position of the sensor alarger flange must be selected than normallyrequired for the horn antenna.

4.4 Measurement through thevessel wall

Radar signals can penetrate very non-conduc-tive products such as glass or plastic. Thisfeature is very important for some applications.In processes where high-purity is requiredsuch as for semi-conductor production orsubstances which are very aggressive it isfavourable that the system remains closed andthe measurement can be carried out throughthe walls of plastic vessels.

A completely non-contact level measurementis possible for products with good reflectingfeatures. Products with good electrical con-ductivity or with an ε

r of more than 10 can be

measured through closed plastic vessels.

Reflection lawsPhysically the fundamental laws of reflectionshould be noted. The radar signal is partlyreflected when penetrating plastic. Anotherpart of the radar signal reaches the product inthe vessel, to reach from the radar sensor asthe real useful reflection.

Gating out of vessel interfering reflections

Emitting power, vessel reflection and radarsignal power reaching the product

The part of the radar signals reflected on thevessel ceiling is detected by the sensor asfalse echo.

When the vessel ceiling or the penetratedplastic window is inclined in an angle of 35° to45° to the sensor axis and the sensor with theantenna keeps a distance to the vessel orwindow of more than 400 mm the false echo isreflected laterally and can no more be re-ceived.

Optimization of the penetrated substanceIf it is not possible to gate out the interferingreflection when penetrating a vessel or a win-dow, the interfering reflection can be nearlydeleted by the optimized thickness of thepenetrated medium.

The interfering reflections are composed oftwo single reflections. One reflection whenpenetrating the substance and one reflectionwhen the waves leave the penetrated sub-stance.

It is a special feature of the reflection on theincoming surface, that it is reflected with aphase jump of half wavelength. The signalsreflected on the outgoing surface are reflectedwithout phase jump.

Mounting and installation: Measurement through the vessel wall

Sensor too close to the outer vessel wall

Wrong

If you want to measure through the wall of aplastic vessel, make sure that the sensor is nottoo close to the outer wall of the vessel. Theemission cone of the sensor must detect theproduct well and must not detect the vesselambient or the vessel wall.


It is hence possible to optimize the thicknessof the penetrated substance so that the tworeflection waves eliminate or compensate eachother.

The following table shows the optimum sub-stance thickness for the most important plas-tics and glasses which are suitable for pen-etration with radar sensors.

Note:The optimum thickness or an integral multipleof the optimum thickness can be also providedby addition of several substance plate of iden-tical materials. The plants must fit flush, with-out gaps.

4.5 False echoes

The installation place of the radar sensorshould be selected so, that no struts or mate-rial inflow cross the radar signals. The follow-ing examples and instructions show the mostfrequent measuring problems and how theycan be avoided.

Vessels with shoulders

Vessel forms with flat shoulders to the antennacan considerably influence the measurementdue to their hard false echoes. Screens abovethese flat shoulders spread the false echoesand ensure a reliable measurement.

Inlet gates, e.g for material mixing with flatupper side pointing to the radar sensor shouldbe covered by an angle screen. Hence thefalse echo is gated out.

Vessels with shoulders (flat shoulders)

Vessel installations

Vessel installations such as e.g. a ladder oftencause false echoes. Provide free access of theradar signals to the measured product whenplanning your measuring point.

Struts

Struts as well as vessel installations can causestrong fale echoes and superimpose the usefulecho. Small screens avoid effectively a directfalse echo reflection. The false echoes arediffusely gated out and filtered out by themeasuring electronics as “echo noise“.

Heavy product movements

Heavy turbulences in the vessel, e.g. bystrong stirrers or strong chemical reactionsaggravate the measurement. A bypass pipe ofsufficient size, provided that there is not build-up in the measuring pipe, always ensures areliable measurement even with heavyturbulences in the vessel.

Products which cause slight build-up can bemeasured by using a bypass pipe with 100mm nominal width or more. In a bypass pipe ofthis size, slight build-up does not cause prob-lems.

Build-up

If the radar sensor is mounted too close to thevessel wall, build-up on the vessel walls willcause false echoes. Position the radar sensorat a sufficient distance to the vessel wall.

4.6 Installation fault

Socket piece too long

When mounting the antenna in a too longsocket piece, strong false reflections arecaused, aggravating a measurement. Notethat the horn antenna protrudes at least 10 mmout of the socket piece. When using a rodantenna, the socket piece must have a lengthof max. 150 mm (with a rod length of 485 mmthe length of the socket piece must be max.250 mm).


In some cases the lower flange antenna isused. Even here it is important that the socketpiece is as short as possible (< 15 mm).

Wrong directing to the product surface

A directing of the sensor which does not pointto the product surface will cause a weakmeasuring signal. If possible direct the sensoraxis vertically to the product surface, to reachoptimum measuring results.

Mounting and installation: Installation fault

Sensor too close to the vessel wall

If the radar sensor is mounted too close to thevessel wall, strong interfering signals can becaused. Build-up, rivets, screws or weld jointssuperimpose their echoes to the useful signalor useful echo. Hence note a sufficient dis-tance of the sensor to the vessel wall.

In case of good reflection conditions (liquidswithout vessel installations) we recommendyou select the sensor distance so that there isno vessel wall within the inner emission cone.For liquids with worse reflection conditions it isuseful that there are also no interefering instal-lations within the outer emission cone. Notechapter “2.1 General installation instructions“.

Foam generation

Strong, dense and creamy foam on the prod-uct can cause faulty measurements. Providemeasures to avoid foam or measure in a by-pass pipe. Check if necessary the use ofanother measuring principle e.g. capacitiveelectrodes or hydrostatic pressure transmit-ters.

5.1 Connection and connectioncable

Safety information

Ensure that the instrument is unpressurizedbefore you start work. Always switch off thepower supply before you carry out clampingwork on the radar sensors. Protect yourselfand the instruments.

Skilled staffInstruments which are not operated with aprotective low voltage must only be connectedby skilled staff.

Connection

A standard two-wire cable can be used asconnection for the output signal. Very often the“electromagnetic pollution“ by electronic ac-tuators, energy transmission and transmittingstations is so considerable that the two-wirecable for the output signals (digital or ana-logue) should be screened.

We recommend to use a screening. Thisscreening prevents against future interfer-ences. Earth the screen of the signal line al-ways at one sensor side and use a low imped-ance earth connection (foundation, plate ormains earth).

Ex-protection

If an instrument is used in hazardous areas,the appropriate regulations, conformity certifi-cates and type approvals for systems in Ex-areas must be noted (e.g. DIN 0165).

Intrinsically safe circuits with more than oneactive facility (instrument delivering electricalenergy) must not be connected. Note thespecial installation regulations (DIN 0165).

Connection cable

Note that the connection cable must be speci-fied for the expected operating temperaturesin your systems.

Cables with intrinsically safe circuits must bemarked (blue) and must not be used for othercircuits.

Set-up

6 Set-up

6.1 Adjustment structure

The radar sensors of VEGAPULS 64 andVEGAPULS 81 series have no direct adjust-ment elements.

All radar sensors are generally adjusted withthe PC and the adjustment software VVO(VEGA Visual Operating). The signal line of theradar sensors is hence superimposed with adigital adjustment signal.

Sensors with digital measuring data transmis-sion (VBUS) can be adjusted beside the PCalso directly with the connected signal condi-tioning instrument VEGAMET 514 V or 515 V.

Note:Always note the following sequence for theset-up of a sensor:- first create new measurement loop.- then carry out the configuration and

parameter adjustment.

By creating a new measurement loop, thesensor is activated. The sensor is set to theparameter to be measured (level, distance)and a measurement loop name can be pro-vided. For sensors with digital output signal,the sensor must be additionally co-ordinatedto an input of the signal conditioning instru-ment or an input of the processing system.

Adjustment with PC

Requirements:- PC; IBM-compatible, with a free standard

interface, operating memory ≥ 4 MB.- Program surface Windows® (up from version

3.0)- Adjustment software VVO (VEGA Visual

Operating)- Interface converter VEGACONNECT or a

standard RS 232-interface cable (for meas-uring systems in conjunction with process-ing system VEGALOG 571).

For adjustment, the PC is connected with thestandard RS 232-connection via the interfaceconverter VEGACONNECT to the measuringsystem. VEGACONNECT is either connectedwith the two-wire output to the sensor signalline (e.g. on a connection socket), pluggedinto the CONNECT-sockets at the front side ofthe signal conditioning instrument or con-nected with the measuring signal terminals ofthe sensor (VBUS-terminals).

Work with the processing system VEGALOG571, connect the PC with the CPU of theprocessing system directly to a RS 232-inter-face cable (standard cable).

Adjust with the signal conditioning in-strument

The signal conditioning instruments are pro-vided with a 6-key adjustment module with textdisplay. The adjustment module ensures likethe adjustment software VVO, the adjustmentof the signal conditioning instrument itself andthe adjustment of the radar sensor.

Before you start the set-up:Do not be frightened by the many pictures,adjustment steps and menus on the followingpages. Carry out the set-up step-by-step viaPC or signal conditioning instrument.


NoteA digital adjustment signal is superimposed tothe 0 … 20 mA signal output. Is the innerresistor of the connected signal conditioninginstrument is less than 100 Ω (e.g. with anindicating instrument), the digital adjustmentsignal is considerably damped. In this caseloop a load resistor R ≥ 100 Ω into the signalline to avoid the low impedance dampingduring the adjustment.

Adjustment

The PC with the adjustment software VVO isconnected to the measuring system.

The individual adjustment and input steps aredescribed in the following (e.g. • choose…; •Start…).• Switch on the power supply of the con-

nected radar sensor.• Switch on the power supply of the con-

nected signal conditioning instrument.• Start your PC and the adjustment software

VVO.• In the entrance screen choose with the shift

keys or with the mouse the point “Planning“and push “OK“. The identification is en-quired.

Set-up

6.3 Save and copy adjustment data

The configuration of the sensors and signalconditioning instruments or the processingsystem can be:- saved “Backup“- administrated (deleted, shifted and com-

ments can be added to the backup) “Editbackup“

- copied (transfer adjustments to other instru-ments) “Restore configuration“

The saving of the instrument adjustments inthe menu “Backup“ corresponds to a databackup. In the menu “Restore configuration“such a data backup can be re-written into theinstruments or transferred to other instruments.

In the menus for saving, copying and adminis-trating of the data you can choose whetheryou want to save, copy or administrate thesensor data to the data set of the signal condi-tioning instrument or the processing system.

If you save e.g. in the menu “Backup/ Sen-sors“ the sensor data, all adjustments andinputs will be saved which you have carriedout in the menu “Sensor optimization“.

Save in the menu “Backup / Signal condition-ing instruments“ the data set of the signalconditioning instrument or the processingsystem, all parameters and configuration dataof a measurement loop except the pure sensordata are saved.

When you have set-up your measurementloop, you can now save the adjustment data.

Adjustment steps with the signal con-ditioning instrument

You adjust the signal conditioning instrumentand the sensor with the six keys on the signalconditioning instrument (–; +; ←; →; ESC; OK).

The basic set-up steps:- First create a new measurement loop with

the menu “Configuration / Configurationmeasurement loop“

- Then co-ordinate the sensor to an input ofthe signal conditioning instrument in themenu “Configuration / Configuration inputs /Input no.…“

- In the submenu “Sensor optimization“ out ofthe menu “Configuration / Configurationinputs“ you then carry out the configurationand parameter adjustment of the sensor.

Hence the set-up of the radar sensor is carriedout. In the main menu “Parameter adjustment“and in the menu “Configuration / Configurationoutputs“ you choose how the sensor valuesshould be processed and provided. E.g. youcarry out the adjustment, the scaling, theparameter adjustment, the current outputs orthe adjustment of the relay functions.

First set-up with the signal condition-ing instrument

After you have connected the radar sensor (s)with a screened two-wire cable to the signalconditioning instrument VEGAMET 514 V or515 V switch on the power supply for the sig-nal conditioning instrument. The signal condi-tioning instrument powers then the sensor (s)with energy.

Types C, D and E of VEGAPULS 81 series arepowered separately. Connect the sensors likethe signal conditioning instrument to the powersupply.

Fault signalsNormally you get fault signals. This is normalfor the first set-up. Hence carry out an instru-ment reset first before you create a measure-ment loop and you carry out the parameteradjustment.


ResetCarry out a reset first to provide a definedinstrument condition. Proceed acc. to thefollowing steps: Push the left key until in thedisplay (right) the appropriate indication ap-pears. “OK…OK“ means that you have to push“OK“ until the requested indication appears inthe display.

Key: Display:OK…OK The fault signal disappears. First the

measurement loop (TAG) withoutmeasured value is indicated.

OK Then parameter TAG1…3 appears.

Note:If no adjustment is made for appr. 15 seconds,the indication jumps back to the stage of themeasured value indication or to the fault sig-nal. Then push again “OK“ until the fault signalextinguishes.
