1 Introduction
ThesensorsoftheARCOseriesareveryrobust,compact
andextremelyreliable.Duringtheirdevelopment,specialcare
wastakentoensurecompliancewithmeteorologicalrequire-
ments.Thesensorsrepresenttheexperienceofmorethan
150yearsofdevelopmentandproductionofwindsensorsat
Lambrechtmeteo.
Thesystemrecordsthehorizontalairowandprocessesthe
measuredvaluesintothemeteorologicalparameterswind
speedandwinddirection.
Thesensorsandothersystemcomponentsaremountedina
splash-proofanddustproofmetalhousing.
Thehousingandthemeasuringelementsaremadeofcor-
rosion-resistantaluminiumalloys.Sensorhousing,cuprotor
andwindvaneareanodized.
2 Start-up · General
Windcanberepresentedbyavectorsize.Foracomplete
description,windspeedandwinddirectionmustbespecied.
Bothcomponentsaresubjecttospatialandtemporalvaria-
tions,sothatstrictlyspeakingtheyapplyonlytothelocation
wherethemeasuringinstrumentisinstalled.Therefore,
specialattentionshouldbepaidtothechoiceofinstallation
location.
Forwindmeasurementsaccordingtothemeteorologicalstan-
dards(forexampleVDI3786,Part2),themeasuringheight
andmeasuringlocationaredecisivecriteriaforrepresentative
anderror-freemeasurements.Ideally,ameasuringheight
of10mabovethegroundisrecommendedforprofessional
measurements.Furthermore,thereshouldbenoobstacles
suchasbuildings,vehicles,airplanesoranythingsimilar
withinaradiusof150mofthestation.Incasesofmobile
measurementsonvehiclesoronmeasuringcontainers,the
aboveconditionsarenotalwaysachievable.Therefore,ac-
ceptablecompromiseshavetobefoundand,ifnecessary,
documented.
Ingeneral,windmeasuringinstrumentsshouldnotmeasure
thespecicwindconditionsofalimitedarea,butindicatethe
typicalwindconditionsinawiderarea.Thevaluesmeasured
atdifferentplacesmustbecomparable.Therefore,when
mountingthesensor,makesurethattheinstallationsiteis
notlocatedintheslipstreamoflargerobstacles.Thedistance
betweentheobstaclesandthesensorshouldbeatleast10
timestheheightoftheobstacles(correspondstothedenition
ofanundisturbedterrain).Ifthereisnoundisturbedterrain,
thesensormustbepositionedataheightthatisatleast5m
higherthantheobstacleheight.
Ifthesensorisinstalledonaroof,theinstallationlocation
shouldbeinthemiddleoftheroofsothatpreferentialdirec-
tionsareavoided.Ifbothwinddirectionandwindspeedare
measured,thesensorsshould,ifpossible,bemountedat
thesamemeasuringpoint,wherebyanymutualinuenceof
thesensorsshouldbeavoided.Theserequirementscanbe
advantageouslyachievedwiththeARCO-SERIAL,ARCO
SDI-12andARCO-NAVsensors.
The sensor must not be mounted on or near transmit-
ters or antennas. A minimum distance of 2 m must be
kept for interference-free signal transmission.

2.7 Installation procedure (brief description)
Thesensorisinstalledinthreesteps:
(1)Attachthecableplugtothesensorandpullthecable
throughthemastifnecessary.
(2)Installthesensoronthemast,butbeforetighteningthe
screwsyoumustalignthesensortotheNorth.
(3)Connectthesensorconnectionsforpowersupplyand
signaloutput.
2.7.1 Mounting the sensor
Thesensorismountedonamastpiece(tube)withanoutside
diameterof50mmandaninsidediameterofatleast40mm.
Beforeattachingtheinstrumentwiththetwogrubscrews
M8x12,connectthecable,leaditthroughthepipeandalign
thesensortothenorth.
Forthispurpose,anappropriatemarkingisattachedtothe
instrumenthousing(seedimensioneddrawing).Alignthesen-
sortotheNorthbeforetighteningthescrews.
Pleasemakesurethatthesensorisrmlyattachedtothe
mast!
Alignment of wind vane
Tomeasurethewinddirection,thesensormustbealigned
tothegeographicalNorthdirection.Inordertoalignthewind
sensorperfectlyandrmlytotheNorth,thedevicehasan
integratedmountingaid.Inthelowerpartofthesensorshaft
thereisagrubscrewwithpinwhichcanbeturnedinwards,
pointstotheNorthandiscountersunkintothecorrespond-
ingslotofthemast(ifpresent),sothatthesensorisaligned
correctlyandinanon-rotatingmanner.Ifnecessary,thegrub
screwcanbeturnedinoroutusinganAllenkey(seedimen-
sioneddrawing).
Turnthemarkonthewindvaneexactlyoverthemarkonthe
sensorhousingshaft.Fixthispositionofthewindvane,e.g.
withanadhesivestrip.Afteralignment,removetheadhesive
stripsagain.
Nowyoucantargetthereferencepointviatheaxisofthe
windvane.Thehousingofthesensormustbeturnedonthe
mountingtubesothatthetipofthewindvanepointstothe
Northernreferencepoint.
Forthealignment,apointintheterrainisdenedwhichis
asfarNorthaspossibleinrelationtothenalpositionofthe
winddirectionsensor.
Thepositionofthereferencepointcanrstbeselectedus-
ingatopographicmap(1:25000).Theexactpositionofthe
referencepointisdeterminedwithacompass,whichcanbe
adjustedhorizontallyonatripod.
Pay attention to compass misalignments!

Whenthetipofthevanepointstothereferencepoint,the
sensorcannallybeattachedwiththetwogrubscrews.
Afunctionaltestinthreedirectionsshiftedeach90°isrecom-
mended.
Observeallrelevantsafetyinstructionswhenmount-
ingasensoronamast.
2.7.2 Power supply and signal cables
Assoonasthesensoriscorrectlymountedandconnectedto
thepre-assembledcable(accessory),thewiresforthepower
supplyandthesignaloutputcanbeconnected.
A4-pinM12cableconnectorisrequiredfortheelectrical
connectionofthesensor.Theshieldingofthecablemustbe
clampedatbothendstotheprotectiveconductor(PE).
Toreducetheriskofinductiveirradiation,thesensor
mustbegroundedcorrectly.
Theexternalconnectionismadebymeansofacentralplug
connector,whichisprotectedinthedevicesocket.Furtherde-
tailsontheelectricalconnectionofthesensorareshowninthe
sections"Dimensioneddrawing"and"Electricalconnection".
Thetypicalpowersupplyofthesensorsis12VDCwitha
currentconsumptionof4mA.Theinputvoltagerangecan
be9...15VDC.
Incaseofpossibleicingoriceformationonthemovingsensor
element,thefunctionislimitedforthedurationoftheicing.
TheoutputsignalofthesensorcorrespondstotheSDI-12
standard.
Thesensorisreadyforuse5secondsafterconnectiontothe
powersupply.
2.7.3 Safety regulations
Since the sensor is often mounted at great heights,
the relevant safety regulations must be followed dur-
ing installation. During the electrical installation work,
the relevant circuits must be disconnected from the
power supply.
The housing must only be opened by authorized
persons!
3 Maintenance
3.1 Regular maintenance and calibration
Thesensorsaredesignedtobeverylow-maintenanceandfor
alongservicelife.Itisrecommendedthatyoucarryoutregu-
larvisualinspectionsforweather-relatedsurfacecontamina-
tionandcleaningifnecessary.Aregularvisualandfunctional
checkofthewindsensorsisrecommended.
If reference measurements are required, it is essen-
tial to ensure that the measured values can only be
compared if the measurements are carried out under
the same conditions. This means that the reference
instrument must be used close to the sensor!
Thesensorisameasuringinstrumentandisthereforesubject
totheuser'sownrecalibrationcycle.
Manufacturerrecommendation:2years.
Wearepleasedtoo󰀨eryouourqualiedmaintenanceand
calibrationservicestoensurethelong-termfunctionandpreci-
sionoftheo󰀨eredcomponents.
3.2 Visual inspections and cleaning
Theuseofthesensorundertherespectiveenvironmental
conditionsrequiresappropriateactions.Itisadvisableto
cleanthehousingandtheshelteratregularintervals.The
intervalsdependontheambientconditionsandthedegree
ofcontamination.Aregularvisualinspectionandfunctional
testisrecommended.
Ifproblemsariseduringthetestswhichyoucannotsolve,

The"ConcurrentMeasurement"enablesthedataloggertomeasuresimultaneouslywithmultiplesensorsonthe
samebus.
The"aC!"commandrequeststhesensortoprocesstheavailablemeasurementdataandwritethemtoanoutput
string.UnlikethestandardsensorsdescribedintheSDI-12documentation,theARCOSDI-12measurescontinu-
ously.ThisiswhytheARCOSDI-12alwaysrespondswith"a000".Thedataisthereforeimmediatelyavailable.
ThisisalsothereasonwhytheARCOSDI-12doesnotsenda"servicerequest"andignoresmeasurementinter-
ruptioncommands.Thedatacanberetrievedwiththecommand"aD0!"(seebelowunder"Senddata").Thedata
isnotoverwrittenuntilthenext"C"or"M"commandandcanberetrievedseveraltimes.
