Interlock - 19 White 19 Allows installation of an emergency stop switch (normally closed). Input
Interlock + 37 Black 37 If CNC interlock is not used, install a jumper wire to close. Input
Motion 18 White 18 Verifies to CNC that a pierce delay is complete and notifies CNC to Output 1
Motion 36 Orange 36 start movement of the cutting machine. For multiple plasma systems on Output
the same cutting machine, this signal should be logically ANDed from all
connected plasma systems.
Transfer 17 Green 17 Notifies the CNC that a successful arc transfer has occurred. This signal is Output 1
Transfer 35 Brown 35 similar to motion, but does not include the programmed pierce delay time. Output
Ground 16 Green 16
Ground 34 Yellow 34
Ground 15 Green 15
Machine Cable Installed + 33 Blue 33 Verifies that the CNC machine cable has been installed. Input 3
Machine Cable Installed - 14 Green 14 Input
System Error + 32 White 32 Notifies the CNC motion controls that a plasma system error has occurred Output 2
System Error - 13 Green 13 Actual error can be queried from serial interface. Output

Spare Input 2 - 10 Red 10 Input
Retract Complete + 28 Blue 28 Verifies to the CNC that the torch has retracted. Output 2
Retract Complete - 9 Red 9 Output

Spare Output 2 - 8 Red 8 Output
Spare Output 3 + 26 White 26 Spare output Output 2
Spare Output 3 - 7 Red 7 Output
Ready to Fire + 25 Orange 25 This signal is used in multiple plasma systems. It notifies the CNC that the Output 2
Ready to Fire - 6 Black 6 THC completed the IHS cycle and preflow is complete, indicating that the Output
torch is ready to fire. This signal and the CNC Plasma Sync signal are
used together. For multiple plasma systems on the same cutting machine
this signal should be logically ANDed to indicate that all machines are ready.
Plasma Sync + 24 Brown 24 This signal is used in multiple plasma systems. It delays torch firing, but Input 3
Plasma Sync - 5 Black 5 allows the preflow gases to flow. This signal and the ready-to-fire signal Input
are used together. For multiple plasma systems on the same cutting
machine, this signal should be removed simultaneously to all connected
plasma systems so all torches will fire simultaneously.
Corner Hold + 23 Yellow 23 On systems with a command THC installed, When this signal is active it Input 3
Corner Hold - 4 Black 4 override the arc voltage control and hold the torch height constant. Input
System Start + 22 Blue 22 Initiates the start of a programmed plasma system cut cycle. This signal Input 3
System Start - 3 Black 3 must be maintained for the duration of the cut. For multiple plasma Input
systems on the same cutting machine, this signal should be activated
simultaneously to all machines.
CNC TX + 21 Green 21 RS - 422 serial transmitter. Transmits data from CNC to plasma system. Input 3
CNC TX - 2 Black 2 Used to set up plasma process information and query for plasma status Input
information. See serial command list for full description.
CNC RX + 20 Red 20 RS - 422 serial receiver. Receives data from plasma system to CNC Output
CNC RX - 1 Black 1 controls. Used to report plasma system status and error information in Output
response to commands from the CNC controller. See serial command list
for full description.
