1710‐PT060PNERev.0Page8of57
2.2 Transmitter’s functions
InstrumentT060Eisaweighttransmitterwithpotentialthresholdrelaymanagementfunction.
Therefore,itisnotatraditionalweighinginstrument,sinceGross,NetandTaremanagementfunctionsarenot
available.
OnlyZEROcorrectionscanbeexecuted(throughexternalinputs)withthepurposetorecoverzeroderivativesor
deviationsrelativetotheweighingsystem.
Theonboardrelaysaremanagedasalarmrelays,thereforetheyarealwayskeptenergizedandarede‐energizedin
caseofalarm.
2.2.1 Management of the calibration
T060Eforeseestheset‐upofatheoreticalcalibration.However,theoperatorcanexecutepotentialcorrectionsduring
thecalibrationphase.Theadvantageofthistypeofset‐upliesinthefactthatthesystemcarriesoutanautomatic
calibration,byknowingthecells’characteristics.

Thesystemisnotvalidincaseofloadcellsnotsupportingdirectlytheentireweightappliedtothesystem(e.g.incase
ofaweighingpinappliedtoaresultantofareturnsystem).Inthiscase,theoperatormustsettheweightvalueused
attheendofthemeasurementchain.
Forexample,incaseofaweighingpinappliedtothefixedcomponentofaliftingsystem,theoperatormustsetthe
valueactuallyliftedbythebridgecrane;forexample,incaseofpinweighing1tonandthecapacityofthebridge
craneconsistingof300tons.Inthiscase,thesignalwillbesetaccordingtothepin’sdatasheetandthecapacitywill
besetto300(correspondingto300tonsofthesystem'scapacity),whilethesensitivitywillbesetaccordingtothe
accuraciesidentifiedintheapplicationofthesystem(forexample,ifitweights200kg,thesensitivitymustbesetto
0.2).

Theresolution(divisionvalue)issettotheresultofthe60000divisions.Higherset‐upsarediscardedbythesystem.
Thesystem’sresolutionisgivenbytheratiobetweencapacityandresolution.
Asystemwitha100Kgcellandaresolutionof0.01isasystemconsistingof10000divisions.
SE G N 1

T060Eforeseesloadcellswithmaximumsignalof3.5mV/V.
PO R T 1

Thevaluesetinthisparameterconstitutesthefullscaleoftheweighingsystem.Itforeseesamaximumvalueof
100000divisions.
SE N S 1

Thevaluecanbeselectedwithintherangefrom50to0.001divisions.

Thechangeofbothsystemcapacityandloadcellsignal(mV/V)causetheclearanceofcalibrationdata
(linearizationsincluded)alreadycarriedout,ofsetpointsvaluesandtheanalogoutputdata.

2.2.2 Sum value function

TheT060Eithedoublechannelweighingversion(Doption)foreseesthepossibilitytohandlethesumvalueofthetwo
channels.Thevaluecanbedisplayedbothpushingandinassociationwithoneormorethresholdrelays
alarms(seechapter2.5).Incaseofsystemswithcapacityordifferentunitmeasure,theoperatormusrealignthe
valuetothesameunitmeasure,decidingwhichofthetwochannelsmustbetakenasreferencechannel.
I.E.:
Channel1F.S.10.00tandchannel21000kfF.S.consideringchannel1asreferencechannel(parameterPRIOR),we
shouldreturnthechannel2toadisplayint.
InordertogetthistheT060EwithparameterMULTIPallowsdividingormultiplyingthechannelvalue.
Inourexampledividingby1000thechannel2valueisdisplayedasforchannel1int.
Accordingtodifferentsystemscapacities,multiplyingordividing,itispossibletosumvalueswiththesamemeasure
unit.
2.2.3 Management of the zero
Theexternalinputscanbeusedtoresetpotentialzeroderivativesordeviationsrelativetotheweighingsystem.The
AZMlimitisvalidinbothways,thereforetheactualfieldis‐100.0%.+100.0%.
Theinputisactiveontheclosingpanel.
Weightresettingiscarriedoutafterconversionandlinearizationoperationswhicharenotinfluenced,causinga
verticaltranslationofthetransmitter’sresponsecurve.
Zeroingaffectsalltransmitters’functions:display,serialtransmission,analogueoutputandthresholdmanagement
arealllinkedtothecorrectweightvalue.
Theresetvalueislostiftheequipmentisturnedoff.
Thenon‐resettotalweightvaluecanbecheckedlocallybypressingkeyDEC:bykeepingthiskeypressed,the
instrumentdisplaysthetotalweightvalue.

1710‐PT060PNERev.0Page10of57
2.2.4 Signal filtering
Theinstrumentallowsintroducingfilteringmethodsofthesignalcomingfromloadcells(FIRfilters).Thismethodis
basedonDigitalSignalProcessing(DSP)modesandallowshandlingatbest,signalscontainingstrongharmonic
components(e.g.generatedbymixers).
Duringtheconfigurationphase,itispossibletoselectthreetypicalfilters(withmovingaverage)and5DSPfilters.
Theformerallowquickerresponsetimesbutarelesseffectivewithregardstointerferences,thereforetheymustbe
usedwhenextremelyquickweightvariationsmustbedetected.
Thelatterallowmitigatinginterferences(sincetheyboastahigherfilteringeffect)atthedisadvantageoftheresponse
timetoweightvariations.
Inbothcases,thehigheristhefilter’snumber,thegreateristhefilteringeffectandtheresponsetimetoaweight
variation.

Forexample,theresponsetoastepweightvariationisshowninthechartbelow,basedontheselectedfilter.
ThechartshowsthatfilterFIR1boastsaresponsetimeofapprox.0.2seconds,whilefilterFIR5boastsaresponse
timeofapprox.2.5seconds.

andpowersupplyconnections)and,incaseananomalyisdetected,aFAILinternalsignalisgenerated.
ByprogrammingoneormorerelaysasFAIL,inadditiontothemessageappearingonthedisplay,allchannel’srelays
areforcedinalarmstatus(theyarede‐energized).Forexample,byprogrammingFAIL1,allrelayssetwithalarm
thresholdsonchannel1and/orthetotal,areforcedinalarmstatus.
