The switch that came with the G0704 is a Kedu KJD17B (note there is a typo in the manual, they list it as a KJD178). The switch has a feature called "Remote Trip" that is the A1 terminal on the back. I have searched to try to understand what that is and how to use it. The G0704 schematic (see below) shows it connected to the spindle direction selection switch. I suspect that what it did was shut off the spindle motor if you try to reverse direction with the switch and the spindle running but it has been years since I had this on my mill I don't recall. Does anyone know what the Remote Trip feature is and how it is used? If it is what I think - some signal on A1 forces the KJD17B to trip - I'd like to cause the switch to trip when the eStop button is pressed.
