Hi GTJim. I have been looking at the very nice wiring diagrams you have made for your router. I have actually based my diagrams on your drawings, since we have very similar setups, and I did not know so much about safety relays.
I noticed that you use a separate time delay relay for the power supply (1 to 10s). But this is not really required. The Pilz PNOZ X9 safety relay has an on-delay of approx. 200ms (manual reset) which is fine for this use. 1 to 10 s is way too long time and only results in heating up the resistor.
