Help with Power Management System

[ro801]

Hi, hope someone can assist, we're fairly new to this and have been somewhat winging it for a few months now. We can't seem to find any instructions on the various components of this PMS, can someone please give us some guidance? Just need some general pointers on how it may function, for example, when connected to electrical hookup does the selected battery get charged or is that the one that's used and the other is charged? Many Thanks

I don't know about your system, but my zig system the charge is only on the les bat not the van. The switch is for the load, when / if you les bat is flat you can change to the van bat.
You can check the charge by putting a volt meter on the bats and move the switches. When they are charging you will see the voltage increase from 12+ volts to 14+ volts on mains hookup
