Anelectronicdeviceswitchesallthe12Vmainsoff,whentheleisurebatteryreachestheminimal
voltagelevelof10V.Itispossibletoswitchonagainallthemainsforabout1minutebyswitching
offandthenonagainthemainswitch.
Theyarealsoautomaticallyswitchedonagainwhenthevoltageis>12V.
Thefridge,theelectricalstepandthemainspowereddirectlyfromB2areexcludedfromthis
device.
TheamperemeterisinsidetheDS-520ANmodule.
-Itmeasuresthecurrentoftheleisurebattery,users’ consumptionandrechargethroughbattery
charger,enginealternatorandsolarpanels.
-Measurerangeis:-40A ÷+40A.
-Measureiscarriedoutasdifferencebetweencharginganddischargingcurrents:apositivevalue
indicatesachargingcurrent,anegativevalueindicatesadischargingcurrent.
Tomeasurethechargingofasolesource(batterycharger,alternatororsolarpanels),turnoffall
usersandotherrechargingsources.
Tomeasuretheconsumptionofasoleuser,disconnectallrechargingsourcesandall
uninterestedusers.
Thisfunctionisusedduringthedrinkwatertankrefillinganditshowsthelevelreachedbythe
water.
Youswitchonthisfunctionbyvisualizingthedrinkwatertankandbykeepingpushedthetank
switchformorethan3seconds.
Whenthisfunctionison,youseegettinglightened,insequence,thehorizontalsegmentsofthe
numberref.18andthepanelemitssoundsinordertowarnthatthetankisgettingfilled:
1shortsoundat75%,2shortsoundsat85%and1longsoundat95%.
Theelectronictankprobemod.“SPE”isacapacitivetankprobe.Itispoweredwith5Vandaback-
signalfrom0to2,5V.
Each8secondsthemicroprocessorgivespowertothetankprobe;itisalsopoweredeachtimeyou
pustthetank-testbutton. Thiswasstudiedinordertoavoiduselessconsumption.
ThetankprobehasbeenalreadyprogrammedbyCBE,butitis stillpossibletocheckthecorrect
workingofthetankprobeanditssettingbyfollowingtheseinstructions:
-activatethefunction
-inthiswaythetankprobegetsacontinuepowersupplyof5V,sothatyoucancontrolwitha
voltmetertheback-signalof2,5Vandyoucanalsoadjust,byusingthetankprobe’strimmer,
possiblesmallvariations.(e.g.:value“0V”=0%,value“2,5V”=100%).
-switchthemainswitchoffandthenonagain.
