Plasma Start and Height Control Disable require +24 VDC to activate. If the CNC outputs can supply
+24V it can be used directly if it is referenced to the 24 VDC Common at J4-2.
If the CNC has relays with NO contacts the 24 VDC available from the SC 3000 at J4-1, 3 & 10 may
be routed through those relays to supply the required input signal.
For other CNC outputs such as single ended open collector user supplied relays will need to be added.
