AIR VANTAGE
®
800 (AU) CUMMINS
ENGINE CONTROLS:
13. RUN/STOP SWITCH -
-RUN position energizes the engine prior to starting. STOP
position stops the engine. The oil pressure interlock switch
prevents battery drain if the switch is left in the RUN position
and the engine is not operating.
14. GLOW PLUG PUSH BUTTON -
When pushed activates the glow plugs. Glow plug
should not be activated for more than 20 seconds
continuously.
15. CIRCUIT BREAKER- For protection of Battery Charging
Circuit.
16. ENGINE STOP BUTTON
Shuts down engine
17. START PUSH BUTTON - Energizes the starter motor to crank
the engine.
18. IDLER SWITCH- Has two positions as follows:
1) In the HIGH position, the engine runs at the high idle speed
controlled by the engine governor.
2) In the AUTO position, the idler operates as follows:
• When switched from HIGH to AUTO or after starting the
engine, the engine will operate at full speed for approx-
imately 12 seconds and then go to low idle speed.
• 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.
• When welding ceases or the AC power load is turned off, a
fixed time delay of approximately 12 seconds starts. 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.
• The engine will automatically return to high idle speed when
there is welding load or AC power load reapplied.
19. Combination Meter Gauge
(4 functions)
1. ENGINE HOUR METER- When the RUN-STOP switch is in
the "ON" position the hour meter displays the total time
that the engine has been running. If the engine is not
started within 60 seconds the hour meter is turned off
automatically. This meter is useful for scheduling
prescribed maintenance.
2. ELECTRIC FUEL GAUGE- When the RUN-STOP switch is in
the "ON" position the electric fuel gauge displays accurate
and reliable indication as to how much fuel is in the fuel
tank. If the engine is not started within 60 seconds the fuel
gauge is turned off automatically.
3. ENGINE PROTECTION LIGHT- A warning indicator light for
Low Oil Pressure and/or Coolant Over Temperature.The
light is off when the systems are functioning properly. The
light will come on and the engine will shutdown when there
is Low Oil Pressure and/or the Coolant is Over
Temperature.
Note: The light remains off when the RUN-STOP switch is in
the "ON" position prior to starting the engine. However if the
engine is not started within 60 seconds the light will come on.
When this happens the RUN-STOP switch must be returned to
the "OFF" position to reset the engine protection system and
light.
4. Battery Charging Light- A warning indicator light for Low/No
battery charge. The light is off when the systems are
functioning properly. The light will come on if there is a
Low/No battery condition but the machine will continue to
run.
Note: The light may or may not come on when the RUN-STOP
switch is in the "ON" position. It will come on during cranking
and stay on until the engine starts. After starting the engine
the light will go off unless a Low/No battery charge condition
exists.
20. COOLANT TEMPERATURE GAUGE- An indicator of engine
coolant temperature.
21. OIL PRESSURE GAUGE- An indicator of engine Oil Pressure.
ENGINE PROTECTION LIGHT- A warning indicator light for Low
Oil Pressure and/or Coolant Over Temperature.The light is off
when the systems are functioning properly. The light will
come on and the engine will shutdown when there is Low Oil
Pressure and/or the Coolant is Over Temperature.
Note: The light remains off when the RUN-STOP switch is in
the "ON" position prior to starting the engine. However if the
engine is not started within 60 seconds the light will come on.
When this happens the RUN-STOP switch must be returned to
the "OFF" position to reset the engine protection system and
light.
AIR COMPRESSOR CONTROLS (22 THRU 24)
22. COMPRESSOR ON/OFF SWITCH
Turns compressor on and off by activating or deactivating the
electromagnetic compressor clutch.
23. combined GAUGE (2 FUNCTIONS)
1. COMPRESSOR PROTECTION LIGHT
The yellow compressor protection light remains off with
proper compressor oil temperatures. If the lights turn on, the
compressor protection system will deactivate the compressor
clutch and put the system in standby mode until the
temperature reaches allowable limits. Check for proper
compressor oil level.
2. COMPRESSOR HOUR METER
The compressor hour meter displays the total time that the
compressor has been running (compressor switch must be
on).
24. AIR DISCHARGE VALVE
Controls flow of compressed air. A 3/4" NPT (National Pipe
Thread) fitting is provided.
25. BATTERY DISCONNECT SWITCH
Battery disconnect switch provides lockout/tagout capability.
Switch is conveniently located on the front bottom of the
machine.
26. THERMAL LIGHT
This status light indicates the Power Source has been driven
into thermal overload. Welding output shuts off to protect the
welding system components and resets when the overload
condition is resolved. The Engine and Air Compressor will
continue to operate.
