Internal component faults (1-nn-n, 2-nn-n, 3-nn-n)
Fault codes in the 1-nn-n, 2-nn-n, and 3-nn-n formats identify possible damage to components
inside the plasma power supply. These faults show on the Power Supply Log screen.
Troubleshoot power-related problems with generators
If a fault occurs while you are using a generator, it is possible that doing a quick restart does
not remove the fault condition. Instead, set the power switch on the plasma power supply to
OFF (O) and wait approximately 1 minute before setting the power switch to ON (I).
Problems with input line voltage (fault codes 0-13-0, 0-60-n, and 0-61-0) can occur more
frequently with some generators. If you consistently see these fault codes, you can
temporarily set the GEN setting to on. This setting is on the Feature Configuration screen
(FEATURE CONFIG). Hypertherm recommends that only experienced operators
change this setting. This setting decreases the system’s sensitivity to changes in current
and voltage from incoming power. Refer to page 149.
Make sure that you set the GEN field to off when you are not using a generator.
If you continue to have problems with input line voltage, disconnect the plasma power
supply from the generator, and connect it to a power receptacle with sufficient power.
Refer to page 51 for generator specifications.

A major fault occurred. These fault codes stop the system from
operating. Do the following.
• Do a cold restart. In some conditions, a
restart can remove the fault condition.
• If restarting the plasma power supply does
not remove the fault condition, a qualified
service technician must repair the system.
Speak to your distributor or authorized
repair facility.
