Hi Steve
Back again.
I found a ground loop in the system. Fixed that and system
is better. How ever when I leave the system on overnight
(and sometimes during the run) I have a "limit switch triggered.
What is generating the noise???
Do I need to put a metal shield between ? and ?
Do I, could I use ferrite cores to help.
I have isolated the inputs with a relay board.
I don't mind spending some $$$ if I knew what to
spend it on.
Thanks again for any help!!!
