5‐1TemperatureSensor

Thetemperaturesensor(pleaseseefigure12)measuresthetemperatureofbatteryorthe
environmentaroundthebatteryandtransfersthedatatothecharger.Withdeviatingtemperature,
thechargingvoltageincreasesanddecreasesaccordingly.

5‐1‐1Functions

zThetemperaturesensortransmitsthebatterytemperaturetothecharger.
zThechargingvoltageisadjustedaccordingtothetemperaturemeasured.

5‐1‐2Installation

zLaythecablesfromthebatteriestothecharger.
zConnecttemperaturesensortotheTEMPsocketofthecharger.
zConnecttemperaturesensortothenegativepoleofthebattery,oruseadouble‐sided
adhesivetapetoattachthesensortothetopofthebatteryorinthevicinityofthebattery.

5‐2RemoteController

Theremotecontroller(pleaseseefigure13)canswitchthechargerON/OFF,halfpowermodeON
/OFF,andequalizationON.


Attachtheremotecontrollerasawellaccessibleplacetoensureeasyaccessofthe


Becarefulwhenattachingtheremotecontroller,forwiringharnesses,cablesandother
componentsthatareintheassemblyrangecouldbedamagedintheprocess..

5‐2‐1Installation

zEnsureapproximately49mmwidth,49mmheightand23mmdepthforthetake‐upofthe

zConnecttheremotecontrollertothecharger.Theconnectioncableisequippedwithtwo
equivalentmodularplugs.
zPlacetheremotecontrollerintotheopeningcreated.Securetheremotecontrollerwithscrews
ontheupperandbottommarginofthefaceplate–usetheavailabledrills.



8‐1ChargingCharacteristic

ThechargercharacteristicisgenerallydesignatedasamodifiedIUoUcharacteristic.



8‐1‐1IPhase(Bulk)

TheSTATUSLEDconstantlylightsred.Inthefirststageofthechargingprocess,thedepleted
batteryischargedwithaconstantcurrentuntilthebatteryvoltagereachedIphasesettingvoltage
(13.5V/13.8Vor27.0V/27.6V).Whenthebatteryreachesthisvoltagelevel,thechargingcurrent
graduallydrops.Whenthecurrentdropsdownto80%,thechargerswitchesovertoUophase
settingvoltage(14.0V/28.0Vor14.4V/14.8Vor28.8V/29.6V).Typicallythebatteryischargedto
70%~80%ofitscapacity.

8‐1‐2UoPhase(Absorption)

TheSTATUSLEDconstantlylightsorange.Thismainchargingphasecouldbesettothemaximumof
4/6/8hoursorunlimited,andthecurrentrisesagaintoitsmaximumvalue.Thecurrentremains
constantaslongasthebatteryvoltageisbelowUophasesettingvoltage(14.0V/28.0Vor14.4V/
14.8Vor28.8V/29.6V).Afterreachingthesettingvoltage,itremainsconstant.However,the
currentdropsagain.Withinthismainchargingphase,thebatteryischargedto95%ofitscapacity.


Thechargingvoltageandtheperiodforthemainchargingphase(Uophase)canbe
selectedusingthedipswitch(S1).

8‐1‐3UPhase(Float)

TheSTATUSLEDconstantlylightsGreen.Ifthecurrentdecreasesto10%orundertheratedcurrent
orifthetimelimitof4/6/8hoursisexceeded,thenthechargerswitchesovertoeconomy
charging(13.5V/13.8Vor27.0V/27.6V).
12


Batteriesmaybechargedseparatelyfromeachotherifthechargershavedouble
chargingorthree‐foldchargingconnections.Theoutputsareseparatedinternallyby
diodes,thustheweakerbatterywillbealwaysfirstchargedtothecharginglevelofthe
strongerbattery.


ThemaximumbatterycapacityshouldNOTexceedthespecifiedcapacity,otherwisethe
functionsoftheindividualchargingphasescouldbeinfluenced.

8‐1‐48‐DayConditioning

IfthebatterychargerstaysatUphasefor8days,itwillswitchbackto3‐stagechargingIUoU,and
stayatUophasefor60minutestorevivethebattery.


8‐dayconditioningwillbeterminatedwheneverequalizationfunctionorhalfpower
modeisactivated.


Whenthechargerisintheequalizationstageorhalfpowermode,8‐dayconditioning
willnotbetriggered.

8‐1‐5Equalization

Thefunctionofequalizationcouldbeactivatedaslongasthebatterychargerisnotinthehalf
powermodeorpowersupplymode.Thefunctionofequalizationwillbeactivatedonlywhenthe
batteryischargedandstaysinUophasewith<25%ofFullloadcurrent.Thebatterychargerwill
chargethebattery3hourswithequalizationsettingvoltage(15.5VorUophasesettingvoltage)
andhalfofratedcurrent.


Oncetheequalizationfunctionisactivated,itcanonlybecancelledbyturningoffthe
batterycharger.


ThebatterychargersLCH‐1215AandLCH‐1230Ahaveanoptiontohavea2Acharging
outputforthestarterbattery.Theoutputvoltageis13.8Vandcanrechargethestarter
