Lincoln VANTAGE 500 - Manual (Page 20)

6. OIL PRESSURE GAUGE
The gauge displays the engine oil pressure when the engine is
running.
7. ENGINE PROTECTION
The yellow engine protection light remains off with proper oil
pressure and under normal operating temperatures. If the light
turns on, the engine protection system will stop the engine. Check
for proper oil level and add oil if necessary. Check for loose or
disconnected leads at the oil pressure sender located on the
engine. The light will remain on when the engine has been shut
down due to low oil pressure or over-temperature condition.
8. BATTERY CHARGING LIGHT
The yellow engine alternator light is off when battery charging
system is functioning normally. If light turns on the alternator or
the voltage regulator may not be operating correctly. The light will
remain on when the engine is stopped and the run/stop switch is
in the run position.
9. IDLER SWITCH
Has two positions as follows:
A) In the “High” position , the engine runs at the high idle
speed controlled by the governor.
B) In the “Auto” / position, the idler operates as
follows:
a. When switched from “High” to “Auto” or after starting the
engine, the engine will operate at full speed for
approximately 12 seconds and then go to low idle
speed.
b. When the electrode touches the work or power is drawn
for lights or tools (approximately 100 Watts minimum)
the engine accelerates and operates at full speed.
c. When welding ceases and the AC power load is turned
off, a fixed time delay of approximately 12 seconds
starts.
d. If the welding or AC power load is not restarted before
the end of the time delay, the idler reduces the engine
speed to low idle speed.
e. The engine will automatically return to high idle speed
when the welding load or A.C. power load is reapplied.
Idler Operational exceptions
When the WELDING TERMINALS switch is in the “Remotely
Controlled” position the idler will operate as follows:
a. When the triggering device (Amptrol, Arc Start Switch, etc.) is
pressed the engine will accelerate and operate at full speed
provided a welding load is applied within approximately 12
seconds.
• If the triggering device remains pressed but no welding load is
applied within approximately 12 seconds the engine may return
to low idle speed.
• If the triggering device is released or welding ceases the engine
will return to low idle speed after approximately 12 seconds.
