Operation
• Circuit breakers interrupt the circuit when an overload or
short occurs. Manual circuit breakers (Type III) can be reset
by depressing the reset button on the breaker. Headlamp
and wiper circuits are protected by the Body Controller.
Type II circuit breakers will reset automatically if the short is
removed from the circuit.
• The various electrical units in the cab and engine
compartments are protected by either fuses or circuit
breakers. The power distribution center is located within the
instrument panel (glove box area) on the passenger side of
the vehicle.
Electrical Load Control and Shedding (ELCS)
Electrical Load Control and Shedding (ELCS) is an optional
feature (standard with sleepers) intended to provide a convenient
means of automatically shutting down electrical loads overnight
in order to conserve energy and deliver sufficient power to start
the engine. The system is active when the engine is not running,
regardless of key state. The ELCS system does not include
provisions for shutting down 120VAC circuits.
The ELCS will begin a sequence of events when the measured
battery voltage is at or below 12.1VDC for a period of 30
seconds. The sequence of events will first start with providing
the visual alert “Load Shedding” to the vehicle operator for
at least 30 seconds.
An audible alert, which consists of a
continuous tone, greater than 3 seconds and less than 6
seconds in duration, will coincide with the start of the visual
alert.
The audible alert can be disabled by a vehicle maintainer if
desired. The sequence will then disable a predefined group
of features/electrical loads. These will remain disabled until
the vehicle’s key switch transitions to the Accessory or ON
positions, and the measured voltage is above 12.1VDC.
Engine
The engine for this vehicle is an electronically controlled diesel
engine. A separate ECM (electronic control module) monitors
and controls all engine functions. This ECM also communicates
with the body electrical system which will generate or activate the
necessary warning indicators to alert the driver of out-of-range
operating conditions.
For complete information on the engine in this vehicle and it’s
optional features, refer to the Engine Operation and Maintenance
Manual supplied with this vehicle.
NOTE: For information pertaining to fuel and requirements refer
to the Engine Operation and Maintenance Manual provided with
the vehicle.
Charge Air Cooler
All MaxxForce® engines are equipped with a charge air cooling
system. The function of the charge air cooler is to cool the hot
compressed air before it enters the engine’s intake manifold.
This system uses ambient air as the cooling medium by allowing
the intake air to pass through a network of heat exchanging
fins and tubes prior to entering the combustion chamber. The
resulting cooler intake air is denser than uncooled air and will
allow additional fuel to be injected for greater power while helping
to reduce emissions.
