Well here we go; the attached schematic (made in Excel) is my interpretation of John’s schematic. For clarity, the ground (copper) wiring on the 120VAC line is not shown. Be easy on me, probably they are a lot of mistakes but my knowledge in electronics is almost zero!
I have also included my three relays data and wiring from the vendor. The markings on the terminals of the relay are my own to identify where each wire will go
I don’t know how to use Relay #3 but I would have liked to energize the spindle cooling water pump and then I could put an on/off switch to run the pump?
Also I don’t like the Homann Estop (SW-06) because on their site it says it is a small switch and for me since this will be the main Estop I would have prefer to use a big red button. Any ideas for a substitute?
