Description

Operation

The ATS-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.

The ATS-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

green led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Usage Type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Usage Type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,the led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yellow led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green led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.

The ATS-10hasgotaTEST mode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the Testmodeis

cancelled.
