Pinouts for the discrete interface cables
Use these tables to identify the signals, pin numbers, and wire colors in interface cables with discrete
connectors.

Remote on/off -
When the input is open, the power to the plasma
power supply, the consoles, and the contactors is dis-
abled.

3 Plasma start + White
4
Input
3
Plasma start -
The CNC starts preflow. If the hold input is not active,
the CNC continues with the plasma arc. The plasma
power supply stays in preflow as long as the hold
input stays active.

Motion -
Tells the CNC that an arc transfer has occurred and
to begin machine motion after the CNC pierce delay
time.

Hold -
The CNC delays plasma arc start. This signal is usually
used in combination with the Start signals to synchro-
nize multiple torches. Start this signal at the same time
as the Plasma Start signal. Stop this signal to fire the
torch.

Input
1
Shield pierceflow -
The CNC tells the plasma system to continue the
shield preflow until after the pierce-delay time. Start
this signal at the same time as the Plasma Start signal.
Stop this signal when the pierce time is complete.
