Two important questions:
1. Do you want the machine to pause if you lose pressure mid-run?
(almost certainly so)
2. Do you want the machine to be able to auto-resume if pressure drops
but comes back?

If the air pressure is related to movement of an axis (or you want to
say it is...) you can use axis.N.amp-fault-in as a place to input an
your error condition. The machine won't be forced to e-stop, but will
not allow the power button to be pressed/stay on.
Same thing should be possible with motion.enable in bit.
For the spindle, maybe motion.spindle-inhibit in bit is what you're
looking for.
If you want the machine to be totally useless then perhaps wiring it
into the e-stop circuit is the way to go. Personally I'm not on board
with that. But about half of the standard conventions in linuxcnc seem
to rub me the wrong way, so it might be just fine with you.

I have air pressure switch to control if there is enough air
pressure. Now I would like that this is also condition for enabling
machine to run.
I would need a little help how to correctly add this to hal.
