Quite interesting browsing thru the control manuals.
This one has an example of using 6 switches in binary code to determine which floor it is at for a 60 floor elevator. 2^6=64
Got the nod to upgrade the Zinc line. They use 6 limit switches in a similar fashion to determine which tank the hoist is over.
You gonna get into the control manuals at some time?
BTW, this has a sex appeal all it's own
