ELECTRONICTANKPROBE

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.
