USING THE STATUS LED TO
TROUBLESHOOT SYSTEM PROBLEMS
Not all of the POWER WAVE® C300 errors will be displayed
on the user interface. There are three status lights that con-
tain error sequences that may not show up on the user inter-
face. If a problem occurs it is important to note the condition
of the status lights. Therefore, prior to cycling power to the
system, 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 sta-
tus lights is for the main control board ( labeled "status", 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.

Non-recoverable system fault. If the Status lights are flashing any
combination of red and green, errors are present. Read the error

Error Code interpretation through 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 (link

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. 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 F.1.
