	Therefore, prior to cycling power to the system,
	check the power source status light for error
	sequences as noted below. This is especially
	important if the user interface displays "Err 006"
	or "Err 100" .

		LIGHT CONDITION		MEANING
	Status LED is solid green (no blinking).			1. System OK. Power source communicating normally
				with wire feeder and its components, if other fea-
				tures and components show they are powered up.
	Status LED is blinking green.			2. Occurs during a reset, and indicates the POWER
				WAVE 355M is mapping (identifying) each compo-
				nent in the system. Normal for first 1-10 seconds
				after power is turned on, or if the system configura-
				tion is changed during operation.
	Status LED is blinking red and green.			3. Non-recoverable system fault. If the PS Status light
				is flashing any combination of red and green, errors
				are present in the POWER WAVE 355M. Read the
				error code 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.
				To clear the error, turn power source off, and back
				on to reset.
	Status LED is solid red (no blinking).			Non recoverable hardware fault. Generally indicates
				nothing is connected to the POWER WAVE 355M wire
				feeder receptacle. See Trouble Shooting Section.
