Corrective action
1. Use the CNC or XPR web interface to make sure that the status of the cutting system is correct and
to make sure that a cutting sequence is not active.
2. Remove the power from the cutting system.
3. Remove the control-side panel from the plasma power supply.
4. Supply power to the cutting system.
5. If the code continues after you supply power to the cutting system, examine the D50 LED on the
control PCB (PCB 1) in the plasma power supply to find if it is illuminated.
If you see this condition... Do these steps...
D50 is not illuminated. There is a problem with the CNC. Refer to the instruction manual for your CNC
for troubleshooting recommendations.
D50 is illuminated. 1. Remove the power from the cutting system.
2. Remove the connector from J14 on the rear of the plasma power supply.
3. Supply power to the cutting system.
4. Continue with the next step.
6. Examine D50 on PCB 1 again to find if it stays illuminated:
