8 – Troubleshooting and System Tests
Fault codes
Fault codes displayed on the LCD screen in “service mode” are in the format N- nn-n. Fault codes displayed on the LCD
screen in “operator mode” appear in the format N- nn. The tables in this section show all digits.
The fault priority is assigned based on the fault code value: the higher the number, the higher the fault priority. If more than
one fault occurs at the same time, only the fault with the highest priority is shown.
Important fault icons
One of the following fault icons may appear on the LCD display in operator mode:
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 ( Figure 17 on page 129), simultaneously press the automatic/manual and current/gas
mode selectors for approximately 2 seconds.
