CAuTION
uSING ThE STATuS LED TOTROubLEShOOT SYSTEM PRObLEMSNot all of the Power Wave  C300 errors will be displayed on
the user interface. There  are three status lights  that contain
error sequences that may not show up on the user interface.
If a  problem occurs  it is  important to note  the condition  of
the status lights. Therefore, prior to cycling power to the sys-
tem, check  the power source  status light for  error
sequences as noted below. 
There are two  externally mounted status  lights located
above the wire drive in the wire feeder compartment. One of
the status lights is  for the main control  board ( labeled “sta-
tus”, and one for the wire drive module. The third status light
is internal and is located  on the input control board  and can
be seen by looking through the left case side louvers. 
There is an audible beeper associated with this input control
board’s status  light. So the  error codes  on the  input board
can be detected through  either the status light  or the status
beeper.
Included in this  section is information  about the Status
Lights and some  basic troubleshooting charts for  both
machine and weld performance.
The status lights  on the  main control  board and the  wire
drive module are  dual-color LED’s.  Normal operation for
each is steady green.  Where as the status light on the input
control board is one color. Normal operation is for the  status
light to be off ( and the buzzer to be off).
Error conditions are indicated in the following Table E.1.

Error Code  interpretation  -
Individual code digits  are flashed
in red with  a long  pause between
digits. These error codes are three
digit codes that all  start with a
number three.
System OK
Meaning
Main control board status light and Wiredrive Status Light
System OK.  Power source is operational, and is communicating normally with all
healthy peripheral equipment connected to its ArcLink network.
Occurs during power up or a system reset, and indicates the POWER
WAVE® C300 is mapping (identifying) each component in the system.
Normal for first 1-10 seconds after power is turned on, or if the system
configuration is changed during operation.
Indicates Auto-mapping has failed
Non-recoverable system fault. If the Status lights are flashing any com-
bination of red and green, errors are present.  Read the error code(s)
before the machine is turned off.
Error Code interpretationthrough the Status light is detailed in the
Service Manual. Individual code digits are flashed in red with a long
pause between digits. If more than one code is present, the codes will
be separated by a green light. Only active error conditions will be
accessible through the Status Light.
Error codes can also be retrieved with the Diagnostics utility(includ-
ed on the Service NavigatorCD or available at www.power-
wavesoftware.com). This is the preferred method, since it can access
historical information contained in the error logs.  
To clear the active error(s), turn power source off, and back on to
reset.
