Read the manual., at 7.3 you find all you need

when do you use filter , water , current pump , maintenance , general alarm mean ?

That depends on your needs - see what you need for a socket and set the function that fits that needs.

and is there a detail menu of explaining of everything in the PCL ?

As said: There is a manual ... read it!
