Hi all,
The Emergency Stop button is connected to the security relay etc and cuts the machine power. My question is not about the safety circuit side of the Emergency Stop but rather the information of its state (pressed or released), so I can display it in the screen. Should I use a Normally Closed (NC) contact or a Normally Open (NO) contact? Is there any rules or norms about that?
Thanks in advance,
Pedro
