I'm studying how to design safety circuit and connections in X11 connector when having door, light curtain and external e-stop. There willl be also external programmable safety relay.
Should I connect light curtains via safety relay to external e-stop or to safety gate pins?
If connecting to external e-stop and acknowledging e-stop by resetting safety relay is it also needed to confirm e-stop message with smartpad?
Or is it simplier to use safety gate and acknowledge for that?
Other question is how to wire internal 24 VDC to external devices via X11? One drawing showed that pins 101 (24V) and 102 (0V) was used. How about using looped back pins 105-108?
Electrician will implement this task but I need to know some basic thing about KRC4 safety circuit.
