Hi everyone, after much searching I cannot seem to find the answer to this one. Does anyone know if a Powermax 380 has an "arc ok" type of signal available in it? I found the manuals, and the maintenance docs on it, but they do not have full schematics that I can tell.
Just wondering if there is easy access to this signal, or if I will need a current transformer to provide this signal for a THC. Seems like it's a good idea to have this, I am just finishing development on my homebuilt PIC-based THC and could leave this feature out of the code, but from what I read, it's a good idea to have the THC able to shutdown the plasma if there are arc problems.....
Thanks. -James
