1. STATUS LED	FIGURE b.2
The status LED indicates system status.	Normal A. WIRE FEED SPEED/AMMETER DISPLAY
operation is a steady green light.

Note: During normal power-up, the LED may flash red and/or green as the equipment performs self tests.

LED condition	Definition
Steady green	System okay. The power source and
	wire feeder are communicating nor-
	mally.
blinking green	Occurs during a reset and indicates
	the power source is identifying each
	component in the system. This is nor-
	mal for the first 10 seconds after
	power-up, or if the system configura-
	tion is changed during operation.
Alternating	Non-recoverable system fault. If the
green and red	power source or wire feeder status
	LED is flashing any combination of
	red and green, errors are present in
	the system. Read the error code
	before the machine is turned off.
	Instructions for reading the error code
	are 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 the power
	source OFF, and then back ON to
	reset. See troubleshooting section.
Steady red	Non recoverable hardware fault.
	Generally indicates a problem with
	the cables connecting the wire feeder
	to the power source.
blinking red	Not applicable.

2.DIGITAL METERS AND OUTPUT ENCODER KNObS (See Figure B.2)

The primary weld procedure settings are controlled and displayed using digital meters and output encoder knobs located at the top of the Power Feed™ 10M Single Wire Feeder control panel.

WFS AMPS	VOLTS TRIM

This meter displays either the wire feed speed or cur- rent value (Amps) depending upon welding process (Mode) being used and the status of the wire feeder and power source. Written below the display is "WFS" and "Amps". An LED light illuminates which value is being displayed on the meter. The knob below the meter adjusts the value displayed on the meters.

Prior to Welding	Description
CV Welding Processes	Meter displays the preset
	WFS value.
CC Welding Processes	Meter displays the preset
	Amps.
During Welding
An Weld Processes	Meter displays displays the
	actual average welding
	Amps.
After Welding
An Weld Processes	The meter holds the actual
	current value for 5 sec-
	onds. The display blinks to
	indicate the Power Feed™
	10M Single Wire Feeder is
	in the "Hold" period. If the
	output is adjusted while in
	the "Hold" period, the
	Power Feed™ 10M Single
	Wire Feeder will revert to
	the "Prior to welding" dis-
	play described above.

Note: If the output knob for the WFS/AMPS is adjust- ed while the Power Feed™ 10M Single Wire Feeder is in the “Hold” period, the Power Feed™ 10M Single Wire Feeder will immediately revert to the “Prior to Welding” display.

The default wire feed speed units are inches/minute and can be changed to meters/minute by entering the "Set-up Menu" in this Operation Section. The wire feed speed is calibrated to within ±2%. Refer to the power source man- ual for calibration specifications of the ammeter.
