Troubleshooting for start signal faults

The Temperature fault Light Emitting Diode (LED) and the System Fault LED flash alternately when the system receives a Start signal from the torch at the same time that the power switch is set to ON (I). This fault can prevent the torch from firing a plasma arc.
