Engine Protection; Idle Shutdown Timer; Cruise Control - Detroit Diesel 60 Operator's Manual

Engine Protection

The DDEC engine protection
system monitors all engine sensors
and electronic components, and
recognizes system malfunctions. If
a critical fault is detected, the AWL
and RSL illuminate. The malfunction
codes are logged into the ECU's
memory.
The standard parameters which are
monitored for engine protection
are: low coolant level, high coolant
temperature, low oil pressure, and
high oil temperature.
This system features a 30-second,
stepped-power shutdown sequence
or an immediate speed reduction
without shutdown in the event a major
engine malfunction occurs, such as
low oil pressure, high oil or coolant
temperature, or low coolant level.
PERSONAL INJURY
To avoid injury from engine
shutdown in an unsafe situation,
ensure the operator knows how
to override the stop engine
condition on a DDEC-equipped
unit.
All information subject to change without notice.

NOTICE:
Engines equipped with the
power-down/shutdown option have
a system override button or switch
to allow engine operation for a
short period of time. Using the
override button so the engine does
not shutdown in 30 seconds but
operates for an extended period
may result in engine damage.

Idle Shutdown Timer

This feature is an optional 1 –
100 minute idle shutdown system.
Its purpose is to conserve fuel by
eliminating excessive idling and
allowing a turbocharger cool-down
period. To activate the shutdown, the
transmission must be in neutral with
the vehicle parking brakes set and the
engine in idle or fast-idle mode.

Cruise Control

Cruise Control is available with any
DDEC engine. Cruise Control will
operate in either Engine or Vehicle
Speed Mode and maintain a targeted
speed (MPH or RPM) by increasing or
decreasing fueling. The targeted speed
can be selected and adjusted with
dash-mounted switches. See Figure 5.
