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.

	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.
