Hello! Is here anybody who can help me with morbidelli 503 author?

We bought used machine and set it up but i have a list of faults and i dont know where to start of what to do.
One of the faults is battery voltage insuff. We ordered new battery and replaced it, but still it doesent go away.

I have 2 floppy discs with the machine, one is plc and other parameters. Is there possible and how to do it, if i can get the stuff from floppies to computer and then to the flashdrive and insert to the machine?
