1 – Troubleshooting
Troubleshoot power-related issues (generator/alternator)
To troubleshoot possible power-related issues with the generator/alternator, do the following checks in the order listed:
1. Is the engine running, and are the main circuit
breaker (top) and the transformer circuit breaker
(bottom) turned ON (
I )?
 If yes, continue with the next step.
 If no, make sure the main circuit breaker (top)
and the transformer circuit breaker (bottom) are
turned ON (
I ). If the engine is not running, check
the engine to see if it requires maintenance. See
Troubleshoot engine issues on page 28.
2. Are you using the auxiliary outlets to power external
devices?
 If yes, disconnect the devices from the auxiliary
outlets. You can exceed the generator’s output
capacity if you power external devices from the
auxiliary outlets while running the on-board
plasma cutting system at full output.
 If no, continue with the next step.
3. Did the circuit breaker for the 120 V auxiliary outlet
trip?
 If yes, reset the circuit breaker by pressing the
button above the 120 V outlet.
 If no, continue with the next step.

The transformer circuit breaker on the
front panel must be turned ON (
I ) in
order to use the 120 V auxiliary outlet.
4. Did the main circuit breaker or the transformer circuit
breaker trip?
 If yes, turn OFF the on-board plasma cutting
system by turning OFF (
O ) its power switch.
Remove any source of external load from the
generator. Reset the main circuit breaker and
the transformer circuit breaker. Turn the plasma
cutting system back ON (
I ).
 If no, continue with the next step.
5. Is the system controller displaying a generator voltage of 480 V for each phase, AC frequency of 60 Hz, and an
engine speed of 1800 RPM? Use the LCD screen on the system controller to check. See
Check engine and
generator status on page 21.
 If yes, continue with the next step.
 If no, have an Hypertherm Freedom 38 PPA repair facility examine the system.
