Description

Operation

TheATS-10providesthemainsvoltagemonitoringandautomatictransferswitching.Intheeventofamains

voltagefailure,theremotestartrelayoutputisenergizedandtheunitautomaticallytransferstheloadfromthe

mainstothegenerator.Microprocessortechnologyallowsexactmeasurement,setpointadjustmentandtiming

functionswiththeparameterstobesimplyprogrammedanddisplayedfromthefrontpanel.

TheATS-10automatictransferswitchcandetectfailureofanyphaseofthemainssupply.Ifatleastoneofthe

mainsphasevoltagesgoesoutsidesetlimits,theunitoperatesasfollows:

-Theledturnsfromgreentored.Themainscontactoroutputisdeenergizedandthe

greenledisextinguished.

-TheremotestartoutputisenergisedaftertheRemoteStartDelayparameterhasexpired.Thegenerator

startmodulereceivesthissignalandinitiatestheenginestart.

-IftheUnitUsageTypeparameter(P00)isselectedas0(Type-1);Whenthegeneratorvoltageiswithinset

limits,theyellowledwillilluminate.Theunitwillallowthegeneratingsettorunwithout

loaduntiltheEngineHeatingPeriodparameterisexpired.Afterthistime,theyellow

ledwillstartblinkingandtheunitwaitfortheGeneratorContactorDelayparameter.

IftheUnitUsageTypeparameter(P00)isselectedas1(Type-2);WhentheEnginerunningsignalis

present,theyellowledwillilluminate.Theunitwillallowthegeneratingsettorun

withoutloaduntiltheLoadgen.signalispresent.Ifthissignalispresent,theyellow

ledwillstartblinkingandtheunitwaitfortheGeneratorContactorDelayparameter.

-Thegeneratorcontactoroutputwillbeenergizedandtheyellowledwill

illuminatesteadilywhentheGeneratorContactorDelayparameterisexpired.

-Ifthemainsvoltagereturntowithinlimits,theledwillturntogreenandtheunitwaits

fortheMainsReturndelayparameterforthemainsvoltagestabilization.

-WhentheMainsReturnDelayparameterisexpired,theyellowledis

extinguishedandthegeneratorcontactoroutputisdeenergized.Thenthegreen

ledwillstartblinkingandthentheunitwillwaitfortheMainscontactorDelayparameter.

-WhentheMainscontactorDelayparameterisexpired,thegreenledwill

illuminatesteadilyandthemainscontactoroutputisenergized.Thentheremotestartoutputisdeenergized.

-Theunitisreadyforanewmainsfailure.

TheATS-10hasgotaTESTmodefeature.Thismodeallowsthegeneratingsettobetestedwithouttakingthe

load.ThismodeisalsocalledEmergencybackupmodewhichkeepsthegeneratingsetrunningandmakesa

quicktransferifamainsfailureoccurs.

Inthismode,Theremotestartoutputwillbeenergizedbutnoloadtransferwilltakeplaceunlesstheoccurrenceof

amainsfailure.Ifamainsfailureoccurs,theloadwillbetransferredtothegeneratingset.Ifthemainsvoltage

returntowithinlimitsandtheMainsReturnDelayparameterisexpired,theloadwillbetransferredtothemains,

butthegeneratingsetwillbekeptrunning.TheremotestartoutputwillonlydeenergizedwhentheTestmodeis

cancelled.
