The power supply connections and the ground
connections for the engine electronics should always
be from the isolator to the battery.

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.
Electrical Shock Hazard. The electronic unit injec-
tors use DC voltage. The ECM sends this voltage
to the electronic unit injectors. Do not come in
contact with the harness connector for the elec-
tronic unit injectors while the engine is operating.
Failure to follow this instruction could result in
personal injury or death.
This engine has a comprehensive, programmable
Engine Monitoring System. The Electronic Control
Module (ECM) has the ability to 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
• Shutdown
The following monitored engine operating conditions
have the ability to limit engine speed and/or the
engine power:
• Engine Coolant Temperature
• Engine Oil Pressure
• Engine Speed
• Intake Manifold Air Temperature
• Engine Intake Throttle Valve Fault
• Wastegate Regulator
• Supply Voltage to Sensors
• Fuel Pressure in Manifold (Rail)
• NOx Reduction System
• Engine Aftertreatment System
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 Troubleshooting for more
information on the Engine Monitoring System.
