Hi Jochen, I'm assuming that your X & Y are
swapped?
Yes. Actually I got it right in the file name.
What is your scope probe ground connected to?
AFAIK it should be on signal ground
Ground is connectet through the mains earth.
The trickier parts are the voltage overload and
voltage good detection circuits in my experience.
DCLO and ACLO signals are OK.
just be careful and remember to
allow those large caps to fully discharge before touching
The PSUs run not on mains
voltages. There is a big mains transformer...
