20. CIRCUIT BREAKERS
These circuit breakers provide separate overload current
protection for each 120V circuit at the 240V single phase
receptacle, each 120V single phase receptacle, the 240V three
phase receptacle, the 120VAC in the 14-Pin connector, the
42VAC in the 14-Pin connector and battery circuit overload
protection.
21. 120VAC SINGLE PHASE RECEPTACLES
These two 120VAC (5-20R) receptacles with ground fault circuit
interruption protection provide 120VAC single phase for auxiliary
power. Each receptacle has a 20 amp total rating. They are
designed to protect the user from the hazards of ground faults.
When the GFCI has tripped there will be no voltage available
from the receptacle. Refer to the AUXILIARY POWER
RECEPTACLES section in the installation chapter for further
information about these receptacles. Also refer to the AUXILIARY
POWER OPERATION section later in this chapter.
22. GROUND STUD
Provides a connection point for connecting the machine case to
earth ground. Refer to “MACHINE GROUNDING” in the
Installation chapter for proper machine grounding information.
23. 240VAC THREE PHASE RECEPTACLE
This is a 240VAC (15-50R) receptacle that provides 240VAC
three phase auxiliary power. This receptacle has a 50 amp rating.
AIR COMPRESSOR CONTROLS (24 THRU 26)
24. COMPRESSOR ON/OFF SWITCH
Turns compressor on and off (standby) by opening and closing
the compressor inlet valve.
25. 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 close the compressor inlet valve and put
the system in standby mode until the temperature reaches
allowable limits. Check for proper compressor oil level.
26. AIR DISCHARGE VALVE
Controls flow of compressed air. A 3/4” NPT (National Pipe
Thread) fitting is provided.
BATTERY JUMP START TERMINAL (27-28)
27. POSITIVE BATTERY JUMP START TERMINAL.
28. NEGATIVE BATTERY JUMP START TERMINAL.
12V battery jump start feature is standard. Covered output studs
for convenient access, and protection against accidental impact.
can be used to jump-start a utility truck with up to 800 cold
cranking amps. Can also be used to jump-start the AIR
VANTAGE® 500 Cummins.
29. BATTERY DISCONNECT SWITCH
Battery disconnect switch provides lockout/tagout capability.
Switch is conveniently located inside the engine compartment.
(SEE FIGURE B.2)
30. AIR CLEANER SERVICE INDICATOR
Air cleaner service indicator provides a Go/No-Go visual
indication of useful filter service life. Also located inside the
engine compartment. (SEE FIGURE B.2)
ENGINE OPERATION
STARTING THE ENGINE
1. Open the engine compartment door and check that the fuel
shutoff valve located to the left of the fuel filter housing is in the
open position (lever to be in line with the hose).
2. Make sure battery disconnect switch is in the on position.
3. Check for proper oil level and coolant level. Close engine
compartment door.
4. Remove all plugs connected to the AC power receptacles.
5. Set IDLER switch to “AUTO”.
6. Set the RUN/STOP switch to “RUN”. Observe that the engine
protection and battery charging lights are on. After 10 seconds,
the engine protection light will turn off.
7. Within 30 seconds, press and hold the engine START button
until the engine starts.
8. Release the engine START button when the engine starts.
9. Check that the engine protection and battery charging lights
are off. The engine protection light is on after starting, the
engine will shutdown in a few seconds. Investigate any
indicated problem.
10. Allow the engine to warm up at low idle speed for several
minutes before applying a load and/or switching to high idle.
Allow a longer warm up time in cold weather.
COLD WEATHER STARTING
With a fully charged battery and the proper weight oil, the engine
should start satisfactorily even down to about 0°F(-18°C). If the
engine must be frequently started below 10°(-12°C), it may be
desirable to install the optional ether start kit (K887-1). For
extreme cold conditions it may be desirable to install the Cold
Weather Heater and Tarp Kit (K2359-1). Installation and operating
instructions are included in the kits.
STOPPING THE ENGINE
1. Switch the RUN/STOP switch to “STOP”. This turns off the
voltage supplied to the shutdown solenoid. A backup shutdown
can be accomplished by shutting off the fuel valve located on
the fuel line.
