Help with Circuit (Control Reliable)


So I'm designing a motor circuit that will have E-stops running to a AB safety relay.

What keeps the Contactor that the safety relay will pull in safe? How do I prevent a contactor from becoming welded?

I've went over some historic drawings of other machines I've seen and the safety relay is always force guided and control reliable, but it always seems as if the contactor were welded shut, nothing would ever know.

Thanks in advance!
