Engine Electronics - Perkins 4008-30 Operation And Maintenance Manual

SEBU9077-02
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.
The engine is controlled by a digital Pandoras
governor. The control system includes the following
components.
• Control unit
• Actuator
• Setpoint adjusters (if equipped)
• Sensors
• Wiring Harness
System Description for Engines
with Electronic Control Unit
The system is controlled by an Electronic control Unit
(ECU). The ECU contains a microprocessor that has
an Electronic Programmable Read Only Memory
(EPROM). The operating parameters for the
governor are stored in the EPROM. The actuator is
connected to the fuel injectors via a mechanical
linkage.
A laptop computer is used to set the operating
parameters of the governor. The laptop computer is
connected to the governor via an interface cable. The
operating parameters for the governor should only be
modified by a trained Perkins representative. Refer to
the Special Instruction, "Pandoras Digital Governor"
for more information.
System Description for Engines
with Electronic Control Modules
The engine has a comprehensive, programmable
i07198825
Engine Monitoring System. The Electronic 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.
