Re: E-stop wiring, which way is correct?
In N.A. there are 3 E-stop methods according to regulations under code, all three result in all power removed from motor devices, I use the typical control relay that has the coil of the relay at the end of the E-stop operating devices, E-stop P.B's, L.S.'s, watch dog timer/charge pump etc.
The relay results in removing power from all contactor coils etc. a contact on the control relay can also be used to advise the controller, Mach etc that an E-stop has taken place.
