Displaying the service screen
You can view system information that aids troubleshooting by accessing the service screen. This screen displays recent
fault codes, arc hours, the software version on your system, and several additional details. You can also run a gas test
from this screen.
For example, if a fault code displays on the status screen (in the format
N-nn
) while you are operating the system, you can
check the service screen for an additional 4-digit fault code (in the format
N-nn-n
). This 4-digit fault code will help a
qualified service technician to diagnose the problem and service the system.
To display the service screen (
on page 129), simultaneously press the automatic/manual and current/gas
mode selectors for approximately 2 seconds.
