1 Introduction
ThesensorsoftheARCOfamilyareveryrobust,compactand
extremelyreliable.Whendevelopingthesesensorsparticular
considerationhasbeengiventothefulllmentofmeteorolog-
icalrequirements.
Thesystemacquiresthehorizontalairowandprocessesthe
measuringdatatothemeteorologicalparameterswindspeed
andwinddirection.
Thesensorsandfurthersystemcomponentsaremountedin
asplashwaterresistantanddust-proofmetalhousing.
Themeasureddataareoutputviaagalvanicallyisolated
RS485interfaceviaModbusRTUafterswitchingonthe
supplyvoltage.
Duetotheirshockandvibrationproofconstructionthesensors
ARCO-Modbusareparticularlyqualiedforuseundersevere
environmentalconditions.Thehousingandthemeasuring
elementsaremadeofseawaterresistantaluminumalloys.
Thehousing,thecuprotorandthewindvaneareanodized.
Anelectronicallycontrolledsensorheatingdeviceallowsfor
operationofthesensoroverthewiderangeof-30...70°C.
2 Start-Up
Windcanberepresentedbyavectorquantity.Foracomplete
descriptionofthewinditisnecessarytospecifyitsspeed
anddirection.Thetwocomponentsaresubjecttospatialand
temporalvariations;thus,strictlyspeaking,thevaluesareonly
validforthesitewherethemeasuringinstrumentisinstalled.
Wethereforerecommendselectingtheplaceofinstallation
verycarefully.
2.1 Installation Conditions
Forprofessionalwindmeasurementsthelocationandheight
ofthewindsensorareimportantforaccurate,correctresults
andrepresentativewindconditions.Ideally,thesensorshould
beinstalled10mabovethegroundonamast.Thereshould
alsobenothinga󰀨ectingwindowwithinaradiusof150m
aroundthesensor.Thismaybebuildings,trees,talltowers,
liftingcranes,movingvehicles,aircrafts,helicoptersorother
obstructions.Inthecaseofmobilemeasurementsonvehicles
oftentheabovementionedconditionsarenotpracticable.
Thenyouhavetondcompromises.
Generally,windmeasuringinstrumentsshouldnotmeasure
thespecicwindconditionsofalimitedarea,butindicatethe
typicalwindconditionsofawiderarea.Thevaluesmeasured
atdi󰀨erentplacesmustbecomparable.Thus,wheninstalling
thesensoryoushouldmakesuretheplaceofinstallationis
notundertheleeofgreatobstacles.Thedistancebetween
theobstaclesandthesensorshouldbe10timestheheight
oftheobstacles(thiscorrespondstothedenitionofanun-
disturbedterrain).
Ifanundisturbedterrainofthiskinddoesnotexist,thesensor
mustbeputupataheightofatleast5mabovetheobstacle
height.
Ifthesensormustbeinstalledonarooftop,theplaceofinstal-
lationmustbeinthemiddleoftherooftoavoidpredominant
winddirections.Ifyouwanttomeasurebothwinddirection
andwindspeed,ifpossible,thesensorsshouldbemounted
atthesamemeasuringpoint,withanymutualinterferenceof
thesensorsbeingavoided.ThesensorARCO-Modbusmeets
thisrequirement.

2.7 Installation Procedure (Brief Explanation)
Theinstallationofthesensorinvolves3steps:
(1)Mountingthecableonthesensorandifnecessarydrawing
thecablethroughthemast.
(2)Mountingthesensoronthemast,butbeforetighteningthe
screwsyoumustalignthesensortothenorth.
(3)Attachingthecabletothepowersupplyandthesignal
acquisitionsystem.
2.8 Mounting the Sensor
Thesensorcanbeinstalledonastandardpipewithanouter
diameterof50mmandaninnerdiameterofatleast40mm.
Beforeattachingtheunitwiththetwo8mmsocketscrews,
thecablemustbeconnected,bydrawingitthroughthepipe
andthesensoralignedtothenorthorintheforwarddriving
direction.Forthispurposethehousingismarkedaccordingly
(seedrawing).Adjustthesensortothenorthbeforetightening
thescrews.
Pleasemakesurethatthesensorisrmlyattachedtothe
mast!
2.8.1 Alignment of Wind Vane
Forwinddirectionmeasurementsthenorthmarkonthe
sensormustbealignedwiththegeographicalnorthdirection.
Toadjustthewindsensorinarmandcorrectmannerinto
thenorthdirectionthisitemisequippedwithanintegrated
mountingaid.Insidetheinnerbottomofthesensorasmallbolt
pointingtothenorthisintegratedtobesetintoacorrespond-
ingslotofthemountingpipe(ifavailable).Thusthesensoris
safelyattached.Ifneededyoucanscreworunscrewthepin
bymeansofanAllenkey.
Youhavetoturnthemarkingonthewindvanesothatitis
exactlyoverthemarkingonthesensorshaft.Fixtheposition
ofthewindvanewith,forexample,apieceofadhesivetape.
Afteralignmenttheadhesivetapehastoberemoved.
Whenyouhavexedthewindvaneyoucanlocatetherefer-
encepointbyaimingatitovertheaxis.Nowyoumustturnthe
sensorcasingonthemountingtubeuntilthetipofthewind
vanepointstothereferencepointinthenorth.
Tosetupthesensor’snorthorientationselectalandmark
whichisasfaraspossibleupnorthwithregardtothenal
positionofthewinddirectionsensor.

2.8.2 Power and Signal Connection
Ifthesensorismountedinthecorrectmannerandconnected
withtherightcable(accessory),youcanattachthewiresfor
thepowersupplyandsignaloutputstothedataacquisition
equipment(computer).
TheARCOsensorrequiresa4-poleM12plugconnector.
Thecableshieldshouldbeconnectedwithbothendsatthe
groundwire(PE).
Toreducetheriskofinductiveinterferencethesen-
sormustbeproperlygrounded(screeningonboth
sides).
Theexternalconnectioniscarriedoutviaacentralconnec-
torwhichislocatedinthehousingbase.Forfurtherdetails
abouttheelectricalconnectionpleaseseesection"Electrical
connections“.
Thetypicalpowersupplyofthesensorsis24VDCwitha
currentconsumptionofmax.920mA(incl.heating).The
inputvoltagerangecanbe20...28VDC.Theheatingofthe
ARCO-Modbushasaheatingpowerof2·9W.
Undermostclimatologicalconditionstheheatingprevents
blockingofthemovingsensorparts.Neitherthecuprotornor
thewindvaneareheated.Inthecaseoficingorformation
oficeonthemovingsensorelementthefunctionisrestricted
fortheperiodoficing.
TheoutputsignalofthesensorconformstotheModbusRTU
toRS485standard.
2.8.3 Safety Regulations
Becausethewindsensorisoftenmountedinex-
posedlocationsatdangerousheightstheinstallation
personnelhavetopayattentiontotherelevantsafety
regulations.Duringtheelectricalinstallationworkthe
externalcircuitbreakermustbeswitchedo󰀨.
