Good find Matt.

I checked out several of our prints to see what all the cycle start contacts go to. Nothing present that I could find on the schematics or connector pinouts. Other than an optional remote start button input. There are only board interconnect block groupings that show front panel and keyboard with very little details for connections specific to the keyboard encoder. The E-stop and Reset buttons are shown, but no cycle start contacts. Must be another rediculous OEM trade secret leaving external contacts and/or full wiring details off the prints. It could be that it is part of the keyboard encoder data package matrix, but at least show the dang contacts and a description of all errors associated, if in fact this turns out to be a simple switch R&R repair!
