Re: All Windings Off setting, Camtronics 5A boards

Hi Ray,

Yes! it DOES stay in when pressed, in fact, someone from the List had
to give me a hint how to reset the switch! I did a little lookup on
contactors, and I did come across "overload". Mine seem to be 24 VAC
(there was a transformer in the "box", and three circuits, L1,L2,L3.
also an NC/NO pair, which don't seem to connect to anything else, but do
close another circuit. There is a little lever on the Siemens
contactor, which closes the circuits as well.

Yeah, what we need is a PDA with Vector CAD, and a wireless internet
connection!
