Connectionofpowersupplyandreceiver
TheSkyFireLCUallowstheconnectionof1s/2sLipobatteries,2sLiFePObatteries,3‐6s
NiMHbatteriesoraBECwithavoltagebetween3.2Vand8.5VtosupplytheLCUaswellas
the9lightchannels.ThecorrespondingsupplypinoftheMPXconnectorismarkedwith
“+LCU”.
Theoperationofthelightchannelsismostefficientat1sLipo(lowheatingoftheresistors
andverylowsystemweight).

TheadditionalAUXoutputcanbesuppliedwiththesamevoltage.Forthis,simplyconnect
thesamebatterytotheappropriatesupplypin,markedwith"AUX”.Thenthe9light
channelsandAUXoutputcarrythesamevoltage.
However,itispossibletoconnectaseparatebatteryofhighervoltageupto13.0Vtothe
supplypinoftheAUXoutput(1s/2s/3sLipobatteries,2s/3sLiFePObatteries,3‐9s
NiMhbatteriesoraBECwithavoltagebetween3.2Vand13.0V).Thisallowsoperationof
afterburnerrings,12VLEDstripsorotherexternalconsumerswithhighervoltages,whileit
wouldnotmakesenseforthelightchannels1‐9duetothelowvoltagelevelofindividual
LEDs.


IMPORTANT:Voltagesupto13.0VsupplymustonlybeconnectedtotheAUXoutput
(+AUX)andnottotheLCUitself(+LCU)!
ThemaximumoperatingvoltageoftheLCUitself(+LCU)is8.5V


DonotconnectanyotherbatterytechnologiesthanthoselistedabovetotheSkyFireLCU.


ThebatterytypeusedmustbeabsolutelyprogrammedwheninstallingtheSkyFireLCUto
allowareliabledeepdischargeandbatterytestfunction,see"ProgrammingMode"!After
programming,theSkyFireLCUmonitorsthebatteryandprotectsagainstdeepdischarge.In
additionthebatteryconditioncanbecheckedusingthebatterytestfunction.


Ifthevoltageoftheprogrammedbatteryiscritical,theSkyFireLCUturnsoffafterafast,red
FlashsequenceoftheMODELED(Error)andcanonlybeputbackintooperationbyagain
pressingthepowerbutton

IfdifferentbatterieswithdifferentvoltagelevelsareconnectedtothesupplyoftheLCUand
theAUXoutput,bothbatterieswillbemonitoredaftersuccessfulprogramming!


Thefollowinginstructionsmustbeobservedforsafeoperation.
‐Allconnectingcablesshouldberoutedinsuchawaythattheydonotcomeincontactwith
movingorhotpartsofthemodel(e.g.servos,rodsorsilencers).
‐TheSkyFireLCUmustbeprotectedfromhumidityandmoisture.


Batteryrecommendation
Thefollowingbatterycapacitiesarerecommendedforonehourofcontinuousoperation,
undertheassumptionthatoneLEDisconnectedtoeachoutputincontinuousoperation.If
severalLEDsareusedinflashmodeorhaveashorterbatterylife,asmallercapacitycanbe
chosen.




Connectionofthebattery
ThebatteryisconnectedthroughaMPXhigh‐currentconnectortotheSkyFireLCU.Itshould
benotedthatdifferentbatterieswithdifferentvoltagelevelscanbeconnectedtothe
variousPLUS‐Pins(Seeschematiconpage4).
IfabatterywithMPXhighcurrentsocketandconventionaloccupancyisconnected(all
PLUS‐pinsoftheconnectoraresolderedtothebatteryPLUS),LCUandAUXoutputwill
automaticallyoperateatthesamevoltage.

Payattentiontothecorrectpolarity:PLUS=RED,MINUS=BLACK.TheMPXconnectorsto
beusedarelabelledwith+and‐.Thecorrectpolaritymustbecheckedagainbeforethe
firststartup.
TheSkyFireLCUisnotreversepolarityprotected!


Connectionofthereceiver
FortheoperationoftheLCU,connectthesignalinput1(Master)tothereceiverusingthe
suppliedpatchcable(yellow‐red‐brown)
Ifdesired,alsoconnectthesignalinput2(AUX)tothereceiver.
TogetfamiliarwiththefunctioningoftheSkyFireLCU,youcanconnectittoaservotester,
ofcourse.
Thesignalinputsaregalvanicallycompletelyisolatedfromthereceivercircuitsothat
perturbationsviatheconnectioncabletothereceiverareexcluded.
Ifthereceiversignalisdetectedandhasnoerrors,theblueLEDsofthesignalinputslightup
permanently.
Ifthereisnosignal(noreceiverconnectedorinvalidsignal/faultycable)theBlueLEDsof
theaffectedsignalinputdonotlightup.
IftheblueLEDsofthesignalinputsflash,thequalityofreceptionshouldbechecked(see
page10).

Ifthereisnosignalforabout30min,theSkyFireLCUturnsoffandcanonlybeputbackinto
operationbyvalidsignalatsignalinput2(AUX).

Assignmentofoutputs
TheSkyFireLCUprovidesatotalof9lightchannels(eachPlus/Minus).Theinputvoltage
(oftheusedbattery)islocateddirectlyattheoutputs.Throughthisthemaximumflexibility
inthedesignofthelightingsystemandtheselectionofLED‐typesisensured.

ConnectionofLEDs
TheSkyFireLCUenablestheoperationofallcommontypesofLEDswithmatchingseries
resistorwherebyeachoutputcanbeloadedwithacurrentofupto3A.MultipleLEDscanbe
connectedinparalleltoanoutput,whileeachLED
requiresitsownresistor.

availablehereonlyforstabilityreasons,plusandminusare
eachpresentinduplicate,butmustbeconnectedtothe
powersupplyonce.

IfseveralLEDsareconnectedinparalleltoanoutput,
thePLUSlinescanbecombined.

DuetothelargecurrentcarryingcapacityofSkyFireLCUtheoutputsaredesignedassocket
(female),sothatashortcircuitisnotpossiblethroughaccidentalcontact.Theconnectionof
LEDstakesplaceviatheprovidedpinbar.Foreasysolderingofthelines,insertthebarinto
thesocketoftheSkyFireLCU.
Nevertheless,ifthecontactviaseparateplugsforeachchannellightispreferred,the
optionalavailableconnectorkitcanbeused.


Forchoosingthesupplygenerallyconsider:Thevoltageshouldbeassmallaspossible,
becauseLEDsdonotneedmorethan3,5V(red/yellowonly2,4V).Everythingabovethat

Batterytest
ThebatterytestfunctioncanbestartedatanytimebybrieflypressingtheSetbutton.
Duringthebatterytest(about3seconds)theconnectedmodellightingisdisabled.The
followingbehaviourisseen:

Trafficlightsequence TheMODELEDchangesfor3seconds
betweencoloursgreen‐ Orange‐ red.This
illustratestheactualbatterytest("charging‐


Displayingchargingstatus Usingthe10orangeStatusLEDsthebattery
charge‐statusisdisplayed.Thescaleofstate




Thevoltageofthebatterycanbereadthroughthe10orangeStatusLEDsofSkyFireLCU.If
all10LEDslightup,thebatteryisfullycharged(charge‐statusscale:100%).
TheMODELEDjumpstogreenifthestateofchargeis>40%,toOrangeifthestateof


Ifthebatteryvoltagefallsunderacriticalthresholdvoltageforseveralseconds(depending
ontheconnectedandprogrammedbatterytype),theSkyFireLCUturnsoffcompletely,in
ordertoavoidadeepdischargeofthebatteryandthustopreventdamageandcanonlybe
putbackintooperationbypressingagainthepowerbutton.


Checkreceptionquality
Ifthemonitoringofthereceptionquality(ReceptionQualityObservation,RQO)was
activatedandprogrammed,theSkyFireLCUpermanentlymonitorsthesignalsofthe
receiverandwarnsofreceptionproblems.

PresstheSetbutton.Afterthebatterytestfunction(MODELEDshowstrafficlight

DisplayQuality
Usingthe10orangeStatusLEDs,thequality
ofreceptionisnowdisplayedonascalefrom
1to10.Forillustrationthereception‐quality‐
scaleisused:


Thequalityshouldgenerallybeinthegreen
zone(8to10),otherwisethereceivingsystem
shouldbecheckedandoptimized.Thelimit
value8correspondstoasignalfailureof<1
secovertheentireperiodof(flight)
operation.

Displaysignalfailures Ifdesired,pressthesetbuttonbrieflyagain
duringthedisplayofreceptionquality(see
above).
Againthe10orangeStatusLEDsshowthe
antennasequence,butquicklyflashing,the
MODELEDlightisred.Thisillustrates,that
nowthesignalfailures(errorframes)willbe
displayed.ForillustrationtheError‐Frame
scaleisused:


Thelittlerednumbersinthebottomrow
representthenumberoflostsignal‐frames.
Thenumbershouldgenerallybelessthan50
(afteraflight),otherwisethereceivingsystem
shouldbecheckedandoptimized.

Averyimportantandusefulfeatureistheindicationofsignalinterferenceduringflight.If
themodelisinFailSafe‐modeduetosignalinterference,theSkyFireLCUstepsintothe
emergencylightingmode.AlloutputsoftheSkyFireLCUblinkveryfast,followedbyashort
breakevery2seconds.Thisbehaviorisexactlyofthesamelengthlikethefault(theFailSafe
phase),butatleast2seconds.

IMPORTANT:
Thedisplayofreceptionqualityandsignalfailuresisanindicationforpossibleoptimizations
ofthereceivingsystemorofitsset‐up/orientation.Thenotificationsarenoguaranteefor
anoptimalreceptionandsafeoperationofthereceivingsystem.

CheckreceptionqualitywithDual‐Receiversystems
Ifadual‐receiversystemisusedinthemodel,connectthetwoinputsofSkyFireLCUtoeach
oneofthetworeceivers.TheSkyFireLCUrecognizesthedifferentmeasurementresultsof
thetwoinputsandthendisplaysthequalityofreceptiontwiceinarow.First,forinput1,

Toenablethemonitoringofthereceptionquality(RQO),theFailSafemodeofthelighting
channelofthereceivermustbeactivated!AsasignallevelfortheFailSafeMode,the
“deepest”possible(‐100%)shallbeprogrammedinthetransceiver.Itisimportantthatthe
FailSafelevelissmallerthanthesmallestpointofactivationofthelightchannels,otherwise
thenormaloperationmodecouldnotbedistinguishedfromtheFailsafemode.


Redflashingmeansthattheactualsignalvalueofthereceiverisnotsuitableasafail‐safe


Ifthereceiver‐monitoringmode(RQO)isnotused,terminatetheprogrammingmodeby
turningofftheLCU(ifthereception‐monitoringwasnotpreviouslyactive)ordisablethe
