CAUTION
USING THE STATUS LED TO
TROUBLESHOOT SYSTEM PROBLEMS
There are two status lights that display error codes. 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 is one externally mounted status light located on the
case front of the machine. This status light corresponds to
the main control boardʼs status. A second 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 boardʼs
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 for the main control board is a dual-color
LEDʼs. 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
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® R350 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 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 (includ-
ed on the Service Navigator CD 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.
