2.19 ELECTRICAL SYSTEM,
FUNCTIONAL DESCRIPTION
Refer to Section 2.19. The electrical system is
comprised of not only the necessary equipment
required to operate the compressor, but also a
system to shut it down in the event of a malfunction.
The components of the electrical system are an
engine starter (with an integral solenoid), battery, a
breaker protected alternator with a built-in voltage
regulator, a compressor discharge temperature
sensor and receiver tank temperature switch (both
will shut down the
compressor temperature exceed 250°F [121°C]), an
ambient temperature sensor, and a fuel level sensor.
This compressor also incorporates an engine coolant
level sensor. This device is located in the bottom of
the deaeration tank. It will shut the compressor down
or prevent it from being started if the engine coolant

level drops too low. In addition, there is a starter
protection relay which prevents accidental starter
engagement after the engine is running or whenever
there is pressure in the receiver tank. Also, should
fuel supply level drop near the bottom of the fuel
tank, the controller will shut down the machine before
the engine runs out of fuel. There are also several
connectors in the main harness that are designed to
receive wiring for factory options such as remote
start, engine air stop valve, and ether start system.
The electrical system also incorporates a lockable
battery disconnect to be utilized for extended periods
of non use and during machine maintenance. In case
of emergency, an emergency stop switch is located
adjacent to the controller on the canopy of the
machine. Section 2.21, and Section 2.22 show the
wiring diagrams for the controller and CEM unit.
