Engine Electronics
Uncontrolled electrical circuit paths can result in
damage to main bearings, to crankshaft bearing
journal surfaces, and to aluminum components.
Engines that are installed without engine-to-frame
ground straps can be damaged by electrical
discharge.
To ensure that the engine and the engine electrical
systems function properly, an engine-to-frame
ground strap with a direct path to the battery must be
used. This path may be provided by way of a starting
motor ground, a starting motor ground to the frame,
or a direct engine ground to the frame.
All grounds should be tight and free of corrosion. The
engine alternator must be grounded to the negative
"-" battery terminal with a wire that is adequate to
handle the full charging current of the alternator.
Engine Electronics
Tampering with the electronic system installation
or the OEM wiring installation can be dangerous
and could result in personal injury or death and/
or engine damage.
This engine has a comprehensive, programmable
Engine Monitoring System. The Engine Control
Module (ECM) will monitor the engine operating
conditions. If any of the engine parameters extend
outside an allowable range, the ECM will initiate an
immediate action.
The following actions are available for engine
monitoring control: WARNING, DERATE, and
SHUTDOWN. These engine monitoring modes can
limit engine speed and/or the engine power.
Many of the parameters that are monitored by the
ECM can be programmed for the engine monitoring
functions. The following parameters can be
monitored as a part of the Engine Monitoring System:
• Operating Altitude
• Engine Coolant Level
• Engine Coolant Temperature
• Engine Oil Pressure
• Engine Speed
• Fuel Temperature
• Intake Manifold Air Temperature
• System Voltage
The Engine Monitoring package can vary for different
engine models and different engine applications.
However, the monitoring system and the engine
monitoring control will be similar for all engines.
Note: Many of the engine control systems and
display modules that are available for Perkins
Engines will work in unison with the Engine
Monitoring System. Together, the two controls will
provide the engine monitoring function for the specific
engine application. Refer to the Troubleshooting
Manual for more information.
