This links covers a remote start setup: http://homemetalshopclub.org/projects/phconv/phconv.html This one is new to me: http://hmin.tripod.com/als/andysm/pages/3phase02.html looks similar to John's schematic. I used this link for mine: http://www.metalwebnews.com/howto/ph-conv/ph-conv.html It seems that if I were clever enough, there might be a way to have a low voltage on the converter output that could sense when a machine is turned on, then start the converter, switch in the high voltage, then shut down when no load is sensed. My converter is close to the machine I use it with, so I just turn it on and off as needed. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
