Troubleshooting for DSP and I/O faults (1-nn-n)

1-nn-n fault codes identify possible damage to components inside the plasma power supply.

Fault codes and fault LEDs

Fault code Fault LEDs Torch LED Description Stops the system from operating?
1-00-0

ON

ON

Red

A DSP PCB fault occurred. Yes
1-20-0 An input/output (I/O) fault occurred. Yes

Corrective action for 1-00-0 and 1-20-0 faults

  1. Do a cold restart.

    In some conditions, a restart can remove the fault condition.

  2. Replace the power Printed Circuit Board (PCB).

    If restarting the plasma power supply does not remove the fault condition, it is possible that the power PCB must be replaced.
