Troubleshooting for PCB hardware protection faults (0-19-9)

A 0-19-9 fault code usually occurs when the input power stops or when power Printed Circuit Board (PCB) hardware protection occurs for components in the plasma power supply.

Fault codes and fault LEDs

Fault code Fault LEDs Torch LED Description Stops the system from operating?
0-19-9 This fault code only shows on a Computer Numerical Control (CNC), or when you use the Hypertherm® cartridge reader (528083) and the Cartridge Reader app to read data from the Hypertherm cartridge. The plasma arc stops. After 10 seconds you can start it again. Fault 0-19-9 can occur up to nine times before it becomes a 2-nn-n or 3-nn-n fault. A 2-nn-n or 3-nn-n fault stops the plasma power supply from operating.

Corrective action for 0-19-9 faults

  1. Decrease electrical noise in the work area as much as you can, and try again to cut when the 0-19-9 fault code goes away.
  2. If you use serial communications, wait for one minute for the fault to go away on its own.

    This fault can occur temporarily on the CNC when you set the plasma power supply to OFF (O).

  3. If the 0-19-9 fault becomes a 2-nn-n fault or a 3-nn-n fault, speak to your distributor or authorized repair facility.
    • A 2-nn-n or 3-nn-n fault identifies a hardware fault with an internal component. A qualified service technician must repair the system.
    • As long as power to the system is not stopped, the 0-19-9 fault can occur up to nine times before it becomes a 2-nn-n or 3-nn-n fault.
    • A cold restart sets the 0-19-9 fault counter back to zero.
