Operational faults

An operational fault code can be for a notification or for a condition that stops the cutting process. Hypertherm® recommends that you do the steps for all faults that occur. Troubleshooting all faults helps you to get optimal cut quality and consumable life.

A label with descriptions for many common fault codes is included with the system. Put the label on the plasma power supply or near your work area for reference.

Fault code	Fault LEDs	Torch LED	Description
None	Flashes	Yellow	The current from the incoming power line is unstable. Stop power to the system and correct the line resonance problem before continuing. Refer to Troubleshooting for AC input power that is not stable.
None	ON ON	Yellow	The gas pressure is too low. Refer to Troubleshooting for low gas pressure faults.
None	Flashes quickly	Yellow	There is no gas supply input. Refer to Troubleshooting for missing gas input faults.
None	Flashes slowly	Yellow	There is a Torch Stuck Open (TSO) condition. Refer to Troubleshooting for TSO and TSC faults.
None	Flashes quickly		There is a TSC condition. Refer to Troubleshooting for TSO and TSC faults.
None	ON ON	Yellow	The internal temperature of the plasma power supply is too hot or too cold. Refer to Troubleshooting for temperature-related faults.
None	ON	Yellow	The Hypertherm cartridge was off, the torch was disconnected, or the torch was in the yellow lock (X) position during a restart. Refer to Troubleshooting for when the Hypertherm cartridge or torch is not ready to cut.
None	Flash alternately	Yellow	The plasma power supply was receiving a signal to start cutting at the same time that the power switch was set to ON (I). Refer to Troubleshooting for start signal faults.
None	Flashes ON	Yellow	An AC input voltage phase loss occurred. This is applicable only for 3-phase models. Refer to Troubleshooting for input voltage faults.
None	Flashes	Yellow	The AC input voltage is too low (>10% less than the rated voltage for 1-phase models or >15% less than the rated voltage for 3-phase models). The AC input voltage is too high (>10% more than the rated voltage for 1-phase models or >15% more than the rated voltage for 3-phase models). Refer to Troubleshooting for input voltage faults.
0-11-0	ON	Computer Numerical Control (CNC) use only	The remote control operating mode is incorrect or not permitted for the installed Hypertherm cartridge. The permitted operating modes for Hypertherm cutting cartridges is 1 (Cut mode). The permitted operating mode for a Hypertherm gouging cartridge is 2 (Gouge mode). Refer to Troubleshooting for remote controller faults (0-11-n).
0-11-1			The remote control output current (A) is incorrect or not permitted for the installed Hypertherm cartridge. The permitted values relate to the minimum and maximum output current (A) for the plasma power supply and the installed Hypertherm cartridge. Refer to Troubleshooting for remote controller faults (0-11-n).
0-11-2			The remote control gas pressure is incorrect or not permitted. The permitted gas pressure relates to the selected process and operating mode, and to the installed torch, torch lead, and Hypertherm cartridge. Refer to Troubleshooting for remote controller faults (0-11-n).
0-12-1	ON	CNC use only	The output gas pressure is too low. Refer to Troubleshooting for incorrect output gas pressure conditions (0-12-n).
0-12-2			The output gas pressure is too high. Refer to Troubleshooting for incorrect output gas pressure conditions (0-12-n).
0-12-3			The output gas pressure is not stable. Refer to Troubleshooting for incorrect output gas pressure conditions (0-12-n).
0-14-0	ON	Flashes yellow	There is a problem with the Hypertherm cartridge installation. Refer to Troubleshooting for Hypertherm cartridge installation faults (0-14-n).
0-14-1			The Hypertherm cartridge is not recognized. Refer to Troubleshooting for Hypertherm cartridge installation faults (0-14-n).
0-19-9	Only displays on a CNC or when you use the Hypertherm SYNC Cartridge Reader (528083) and app to read data from a Hypertherm cartridge.		The input power stopped. Or, power PCB hardware protection occurred for components in the plasma power supply. Refer to Troubleshooting for PCB hardware protection faults (0-19-9).
0-40-5	ON	Yellow	The duty cycle for the plasma power supply was exceeded. Refer to Troubleshooting for duty cycle faults (0-40-5).
0-50-1	ON	Yellow	The torch-lock switch is set to the yellow lock (X) position. Refer to Troubleshooting for torch-lock switch faults (0-50-n).
0-50-2			The torch-lock switch is set to the green "ready to fire" position, but the torch is not prepared to fire. Refer to Troubleshooting for torch-lock switch faults (0-50-n).
0-50-3	ON		The plasma power supply is reading data from the Hypertherm cartridge. Refer to Troubleshooting for torch-lock switch faults (0-50-n).
0-52-0	ON ON	None	The torch is not connected. Refer to Troubleshooting for torch connection faults (0-52-0).
0-98-1	ON	Yellow	A Radio Frequency (RF) communication failure occurred between the Hypertherm cartridge and the torch. Refer to Troubleshooting for an RF communication fault (0-98-1).
0-98-2	ON	Flashes yellow	A communication failure occurred between the torch and the plasma power supply. Refer to Troubleshooting for a plasma power supply or torch communication fault (0-98-2).
