High Inlet Manifold Air Temperature - While this
feature is part of the monitoring system it will
not affect operation of the engine other than the
normal power loss you would experience without
a monitoring system. The driver will simply be
alerted and a fault logged as it is when any one
of the monitored conditions exceeds acceptable
limits.
Available:
All electronically controlled on-highway engines
covered in this handbook
Range:
Range Cat Default
*Warning
Derate
Shutdown
Derate
*Warning is for emergency vehicles only
Advantages:
If a monitored engine fault should occur, such as low oil
pressure, high coolant temperature, low coolant level,
and the engine monitoring system is in one of its active
modes, the engine electronics can warn the driver,
derate or even shutdown the engine, depending upon
how the system has been programmed. The additional
expense of “add-on” systems can be avoided by using
the Caterpillar system.
Disadvantages:
None
Recommendations:
✔ Use the setting which best matches your
requirements, however, Caterpillar recommends
using the Shutdown mode for most applications.
✔ If another monitoring system is used, set the
Caterpillar system to Off to avoid interaction with
the installed system.
✔ When specing your truck ask that the coolant level
sensor be installed and activated. This may be an
additional cost option, but less than the cost of
another monitoring system.
