11. START / GLOW PLUG SWITCH - Energizes the starter
motor to crank the engine. With the engine RUN /STOP / IDLE
switch in the "RUN" position, push and release the START
button to start the engine:
• This switch has an amber light (top of switch) to indicate
glow light, this engine will automatically apply power to the
glow circuit and indicator light will turn off when glow is
completed. (Engine will crank but will not start until glow
cycle is completed)
• This switch also has a red light (bottom of switch) it will
light up when there are faults with the engine. (Check
engine light comes on) Field Service Shop will need to
connect to diagnostic plug to read error codes.
12. 12-PIN CONNECTOR - For attaching optional remote
control equipment. The K2909-1 (12-pin to 6-pin) adapter
cable is included for attaching to accessories requiring the
6-pin connector.
13. 14-PIN CONNECTOR - For attaching wire feeder control
cables. Includes contactor closure circuit, work sense lead
remote control circuit, and 120V and 42V power.
14. WELD OUTPUT TERMINALS - These 1/2" - 13 studs
with flange nuts provide welding connection points for the
electrode and work cables. For positive polarity welding the
electrode cable connects to the "+" positive terminal and the
work cable connects to this "-" negative terminal. For nega-tive
polarity welding the work cable connects to the "+" posi-tive
terminal and the electrode cable connects to this "-" neg-ative
terminal.
15. VRD (VOLTAGE REDUCTION DEVICE) INDICA-
TOR LIGHTS - On the front panel of the Vantage
LE500X are two indicator lights. A red light when lit indicates
OCV (Open Circuit Voltage) is equal to or greater than 30V and a
green light when lit indicates OCV is less than 30V.
The VRD must be active for the lights to be enabled. When the
machine is first started with VRD enabled, both lights will
illuminate for 5 seconds.
These lights monitor the OCV and weld voltage at all times.
When not welding the green light will illuminate indicating that
the VRD has reduced the OCV to less than 30V. During welding
the red light will illuminate whenever the arc voltage is equal to
or greater than 30V. This means that the red and green light
may alternate depending on the weld voltage. This is normal
operation.
If the red light remains illuminated or both VRD lights flash when
not welding, the VRD is not functioning properly. Please refer to
your local field service shop for service.
If VRD is turned ON, but no lights are illuminated, refer to the
trouble shooting section.
NOTE: See page A-2 to change the on/off position of the VRD
switch.
16. HIDDEN MENU BUTTON - The hidden setup menu can
be accessed any time the machine is on with the engine run-
ning and not in a welding arc (arc off or OCV). To access,
press the HIDDEN MENU push button (Figure B.3 - functions
are listed in following section) with the appropriate tool
provided with the machine.
NOTE: The menu system will exit automatically if any of the fol-
lowing conditions are met:
•
If no settings are changed for 10 seconds.
•
If the mode selection switch position is changed.
•
If the arc status changes to arc or short.
•
If the entire setup menu sequence is cycled through.
17. LOCAL/REMOTE SWITCH - In the LOCAL position,
machine output control is set by the OUTPUT CONTROL knob
on the front of the machine. In the REMOTE position, the
441X/
®
machine output control is set by the remote inputs. This con-
trol is not active in ArcLink
18. WIRE FEEDER VOLTMETER POLARITY SWITCH
Matches the polarity of the wire feeder voltmeter to the polar-
ity of the electrode.

20. 20A BREAKER FOR 120V RECEPTACLE AND
120V WIRE FEEDER
21. 20A BREAKER FOR 42V WIRE FEEDER
22. 50A BREAKER FOR 120V/240V AND 240V
RECPTACLES
23. 20A BREAKER FOR BATTERY
24. 20A BREAKER FOR 120V RECEPTACLE
25. 120/240 VAC SINGLE PHASE RECEPTACLE
This is a 120/240 VAC (14-50R) receptacle that provides
240 VAC or can be split for 120 VAC single phase auxiliary
power. This receptacle has a 50 amp rating. Refer to the
AUXILIARY POWER RECEPTACLES section in the
INSTALLATION chapter for further information about this
receptacle. Also refer to the AUXILIARY POWER OPERATION
section later in this chapter.
