Whenthebatterychargerischarging,anelectronicdeviceallowsarecharging(max2A)ofthecar
battery(B1),thesystemgivesprioritytotheleisurebattery(B2).
byalternator:throughtheseparatingrelais,whentheengineisstarted.
by230Vnet:buffersystemthroughbatterycharger
bysolarpanel:throughsolarregulator.
Anelectronicdevicecontrolledbytheignitionswitchesonthebatteriesparallelwhenthecarbattery
voltageisover13.5Vandswitchesoffwhenengineisofforvoltageislowerthan12.5V.Thisdevice
operatesonlyiftheB2leisurebatteryisconnected.
Thisdevicecontrolstherelaysoftheusersdependingfromexitsimulating+OUT D+(3wayfunction
fridge,awninglight,antennamotion,etc.).
inthecaseofinstallationofequipmentthatneedspermanentexclusionofthebatteryparallelrelay
(ref.1),youmustremovetheR37resistor(ref.2). Theresistorcanberemovedusingawirecutter,
beingcarefulnottodamagethePCBtracesbelow.
