1.1 Introducon
ThisinstruconmanualreferstotheInterfacemodelWTSTLtensionlinktelemetryopons.Beforeinstalling
oroperanganyInterfacetensionlink,thisandanyreferencedocumentsshouldbereadandunderstood.
IncompliancewiththeMachineryDirecve,Interfacetensionlinkloadcellswillbesuppliedwiththefollowing
documents:InstruconManualandCalibraonCercate.
1.2 Markings CE
Eachtensionlinkwillbemarkedwithanindividualserialnumber,CElabelandtheSWL(safeworkingload)of
the tension link.
1.3 ElectromagnecCompability(EMC)
The electromagnec compability of the load cell device can only be assessed in conjuncon with the enre
installaon, including its control systems. The machine builder who installs this partly completed machinery
into a machine is responsible for compliance with the EMC direcve.
1.4 InstallaonandOperaon
Toensuresafeandtrouble-freeinstallaonofthetensionlinkmeasuringdevice,thetensionlinkmustbe
properlytransportedandstored,professionallyinstalledandplacedinoperaon.
Unpacking
Beforeremovingthetensionlink,inspectthepackagingforsignsofdamageandimmediatelyinformthe
supplierifanydamageisfound.Unpackthetensionlinkcarefully,takingspecialcarewithcablesandbe
awaretothepossibilityofdamaginglow-rangedevicesbymishandling.Ensurethatcalibraonandinstrucon
informaonisnotinadvertentlydiscarded.
ChecksPriortoInstallaon
• Checkthatthetensionlinkhasbeensuitablyselectedfortheenvironmentitisbeingplacedinto.Any
adversetemperature,corrosiveorpotenallyexplosiveenvironmentsmayaecttheoperaonallifeand
thesafetyoftheproduct.
• Ifthetensionlinkisedwithatelemetrymodule,checkthatthe2AAAbaeriesarecorrectlyinstalled,
thatthetwoREDclipsonthetelemetryhousingareclosedandthatthebaerycoverissecure.SeeFigure

Installaon
Tensionlinkloadcellsarenormallyclassiedasportabledevices,andsothecorrectinstallaoniscricalto
ensuringproductlifecycle.Toavoiddamageorlossofaccuracyduringinstallaon,thefollowingpointsshould
befollowed.
• ThedireconoftheloadappliedtoalinkshouldbelinearasshowninFigure2.
• Ensurethetensionlinkloadcelldoesnotexperiencetorqueorbendingforcesduringoperaon.
• ThetensionlinkloadcellshouldonlybeloadedintensionusingtheØCholesasshowninFigure2.See
gure3fortwocommonexamplesofinstallaons.
• ForopmalperformanceaghttolerancewiththeØCloadingholesisrecommended.
• Ifthetensionlinkisedwithatelemetryunitthenensurethataclearline-of–sightbetweenthe
transmierandreceiverismaintainedandthatobjectsorstructuresarekeptatleastonemeteraway
fromantennaewhereverpossible.TheinstallershouldalsorstreadtheWTSTelemetryUserManual

Electrical Checks
Thecorrectconneconofatensionlinktoaninstrumentiscricaltoachievingandmaintainingthe
performanceandreliabilityoftheloadcell.
• Tensionlinkcablingmustbekeptawayfromhighpowercablesandequipment,highoutputRFequipment
andinducveloadsandgenerators.
TensionlinkOutput
Whensengupyourtensionlinkthefollowingpointsshouldbeacknowledged:
• Thezeroloadoutputgivenonthecalibraoncercateistheoutputofthetensionlinkwhennoloadis
applied.Thisincludestheremovaloftheloadcausedbyanyliingaccessories.
• Theloadonaninstalledtensionlinkwillcompriseoftheweightofyourassembly(includingsheaves,
blocks,shackles,ropes,hooksetc.)andtheacveload(loadlied).Therefore,theoutputwithnoacve
loadwillbegreaterthanthezerooutputindicatedonthecalibraoncercate.
ChecksAerInstallaon
• Withthetensionlinkinstalled,checktomakesurethatthedisplayedoutputisnotnegave,asthismay
indicateeitherafaultoracompressiveforceisbeingappliedtothetensionlink.SeeFigure2onprevious
page.
• Whenapplyingloadtothetensionlink,theoutputshouldincreaseintheposivedirecon.Usethe
calibraoncercateforreferenceastotheoutputobservedatcertainloads.
1.5 Calibraon
AllInterfacetensionlinkloadcellsarecalibratedintraceabletestmachinestobestsimulatenormalloading
condions.
Ourgoalistomatchtheloadingcondionsthatwouldbeexperiencedinservicebutitisnotpossibletototally
simulatetheon-sitestructureforeverytensionlinkmanufactured.Itisforthisreasonthatforopmum
systemaccuracy,acalibraoninthenalassemblyisrecommended.On-sitecalibraonshouldbeperformed
withtheinstrumentthatisbeingusedwiththistensionlinkloadcell.
1.6 Warnings / Hazards
Tensionlinksarehighlystresseddevicesandcommonlyhavesafetyfactorsbetweenthreeandvemes
theratedcapacityunderstaccondions.Fagueapplicaonsandenvironmentalfactorscancontributeto
reducingthismargin.Theusershoulddeterminemediaeectsontheexposedtensionlinkmaterials.Wherea
corrosiveenvironmentispresent,tensionlinkscanoenbemanufacturedfromcorrosionresistantmaterials
or,alternavely,isolaonbarrierscanbeemployedbetweenthecorrosiveenvironmentandthetensionlink.

Thefollowingpointsshouldbefollowedtoavoidpotenallyhazardoussituaons:
• Donotweldneartoinstalledtensionlinks,asleakagecurrentsmaydestroythetensionlink'selectric
circuits.
• Tensionlinksaresealedunitswhichmustnotbedismantled.Damagedtensionlinksshouldbereturnedto
Interfaceforrepairandre-calibraon.
• Theaccuracyofthesystemisdependentuponcorrectinstallaonofthetensionlink.
• Tensionlinkloadcellsmustnotbesubjectedtoshockloads,suchasusingahammertoforceanassembly
together(ngclevispinsintothemounngholes).
• Thetensionlinkloadcellshouldneverbeplacedinapotenalexplosiveenvironmentunlesstheproductis
suitablycered(ATEXorIECEx).
1.7 InspeconandRepair
Repair
InterfacereccomendsthatallpreparedandserviceoftensionlinkloadcellsbeperformedbyInterface.
Inspecon
AllInterfacetensionlinkloadcellsshouldbesubjecttoperiodicinspecon,whichshouldinclude,butisnot
exclusivetothefollowingchecks:
• Compleonofthesafetychecksaerinstallaon.
• Checkoutputatzeroload(shiinzerooset).Verifyagainstcalibraoncercate.
• Inspecttoseeifthetensionlinkhasbeendamaged/wornorchemicallyaacked(fromacorrosive
environmentorlubricantsetc.).
• Aeranyseriousoperangincident,repeattherstthreechecksabove.
• Fortensionlinksedwithatelemetrymodule,checkthatthebaeriesarecorrectlyinstalled.The
baeryholdershowspictoriallythecorrectorientaon.
• Fortensionlinksedwithatelemetrymodule,checkforanysignsofwateringresstothebaery
compartmentandforanybaerycorrosion.
• Intheunlikelyeventofthisdevicefailing,tnewbaeries(ifapplicable)andre-test.Onlywhenthishas
