SmartBank SmartBank Automotive owners installation manual General Description SmartBank and SmartBank Automotive are auto battery combine controllers that monitor two battery banks and by making accurate measurements decide when to parallel them to allow simultaneous charging and when to separate them to prevent cross discharging The two units SmartBank and SmartBank Automotive are identical in features functions and physical form The only differences are the options of the remote panel switch for each unit and the power saving feature which is not incorporated in the Automotive version Unlike conventional split charge systems using diodes or relays SmartBank is not affected by where the charge is coming from nor does it have to be separately controlled by alternator signals manual switches etc There is nothing for you to forget Neither does it suffer from the voltage drop problems of split charge diodes SmartBank automatically controls charging of 2 battery banks no matter which battery bank is being charged Whether it is an alternator solar panel wind generator or AC powered charger SmartBank will take care of it automatically You make sure your charge source is connected to one battery bank SmartBank will take care of the other one totally automatically No more flat engine batteries because you forgot to switch the battery selector over No more uncharged house bank Not only is SmartBank better than a standard split charge

11. s section Reduced power consumption In a power critical application it may be desirable to reduce even the very small power consumption of SmartBank by installing an on off switch This can be achieved by fitting a SPST switch in series with R33 on the PCB This will kill all power to the control circuitry and reduce the current consumption of SmartBank from 700uA to around 100uA This switch could be replaced with a relay controlled by other equipment Defeating the power save feature At the time SmartBank connects it send a 350mS full power pulse to the relay coil This ensures that the relay closes fully and quickly SmartBank then reduces the power delivered to the relay coil by pulsed switch mode techniques This has several advantages A It drastically reduces the connected current draw of SmartBank B It vastly increases the operating life of the relay due to reduced coil dissipation most relay failures are due to the coil failing not the contacts C It enables the use of relays which are not continuously rated to be utilised in continuous duty D It enables a 12 volt relay to be used in a 24 volt installation provided that 12 volt relay is rated for continuous duty In some installations it may be advantageous to defeat the power save feature One example being an installation in which it is desired that some external equipment can override SmartBank and disconnect or connect the relay in an AND OR type scenario Disconnec

13. ting the feed from SmartBank to the relay coil will disconnect the relay ok but will not always ensure it can be reconnected due to the relay requiring the full power pulse to close correctly For this reason the power save feature can be disabled by soldering across the solder contacts on the PCB as shown in the diagram Note that the power save feature is disabled by default in SmartBank Automotive Battery compartment venting Wet cell batteries give off explosive gases when being charged In many installations natural ventilation is sufficient to vent these gases to the outside world but in others it may be necessary to force vent these using a fan SmartBank is ideal for this additional use by simply using another relay energised by SmartBank to control the fan Obviously a fan and relay suitable for explosive atmospheres must be used 11 Additional relays SmartBank can safely provide power to relays with a total normal coil current consumption of 3 amps note that this will not be the actual current draw due to the power save feature so additional relays can easily be added to parallel say a bow thruster or windlass battery If there is any doubt as to the total coil current consumption then use a small relay energised by SmartBank to control the coil current to the larger relays Component identification aaa Connect Disconn Hold Powersave Cc_ a po ETA E ep R33 FOO REY F SmartBank 12 24
