Bridgeport S2I2 Head Control

[Jay Kyle]

Hi Everyone,
I'm doing an Ajax conversion on my Bridgeport, and want to add a few buttons to the head like in some of the photos on the Ajax site. What I don't know is should I buy NC or NO buttons for:

-Cycle Start
-Cycle Stop
-Tool Check
-Feed Hold

Does anybody have any ideas? I'll be hiring out the PLC as I just don't have time to learn it all.

Thanks

Jay

Fail-safe design generally indicates that "go" buttons be normally-open, and "stop" buttons be normally-closed.

So you should use NO for your remote Cycle Start and Tool Check buttons, and NC for your Cycle Cancel and Feed Hold buttons.

Thanks the design concept was exactly what I needed!
