Emergency Push Button Pin Wiring

SANJR

Hi I am planning to install a Emergency Push Button to the IO Connector of Duet 3D Mainboard 6HC.

The Push Button has three wires 1. NO (Normally Open) Wire 2. NC Wire 3. C Wire

To what Pins should these wires be connected to Duet 3 IO Pin's?

I am attaching the Specification Sheet and Wiring Photo of this Emergency Push Button for Reference

@SANJR normally closed and ground connected to groun and iox.in on the io connector

@jay_s_uk Hi Thanks for the reply
Inference that NC Wire should be Connected to the GND Pin on the IO Connector. And the C and NO to which on the IO Connector to be connected?

@SANJR C is common so it need to connect to Gnd, and NC pin to iox.in pin on duet board...the NO wire is left alone without connection

Since the next question will likely be 'what do I put into my config.g file?', this is my section for the emergency switch that I just installed after having procrastinated waay too long and having killed some expensive hardware. I am connected to the io7 port between ground and io7.in. It doesn't matter which wire goes to which of those two pins:

; Set up EMERGENCY STOP button
M950 J1 C"IO7.in" ;creat input pin number 1 (J1) which is connected to the input of io7 connector
M581 P1 T0 C0 S0 ; configure input pin number 1 (P1) .... T0 = emergency stop on trigger, C0 = allow trigger at any time (not just during print), S0 triggers on falling edge (NC)

My emergency switch/button locks in the activated position. I have to twist it to let it pop back out to the 'run' position. Note that DWC gives you a message saying something about resetting the machine. You have to click on that message after the emergency stop is released in order to restart things.
