USING THE STATUS LED TO
TROUBLESHOOT SYSTEM PROBLEMS
Not all of the POWER WAVE ® R500 errors will be displayed
on the user interface (if it is installed). 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 system, 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 board and input control boardʼs status.
Included in this section is information about the Status
Lights and some basic troubleshooting charts for both
machine and weld performance.
The status light for the main control board and input control
board are dual-color LEDʼs. Normal operation for each is
steady green.
Error conditions are indicated in the following chart Table

Occurs during power up or a system reset, and indicates the POWER WAVE ® R500 is mapping (identify-
ing) 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 combination 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 sep-
arated by a green light. Only active error conditions will be accessible through the Status Light.
Error codes can also be retrieved with the Power Wave Manager Utility 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.
