Use the Emergency Stop Button (if equipped) ONLY
in an emergency situation. Do not use the
Emergency Stop Button for normal engine stopping.
After an emergency stop, DO NOT start the engine
until the problem that caused the emergency stop
has been corrected.
Stop the engine if an overspeed condition occurs
during the initial start-up of a new engine or an
engine that has been overhauled. This may be
accomplished by shutting off the fuel supply to the
engine and/or shutting off the air supply to the
engine.
To stop an electronically controlled engine, cut the
power to the engine.

Electrical
System
Never
disconnect
any
charging
unit
circuit
or
battery
circuit
cable
from
the
battery
when
the
charging
unit
is
operating.
A
spark
can
cause
the
combustible
gases
that
are
produced
by
some
batteries
to
ignite.
To
help
prevent
sparks
from
igniting
combustible
gases
that
are
produced
by
some
batteries,
the
negative
“
−
”
jump-start
cable
should
be
connected
last
from
the
external
power
source
to
the
negative
“
−
”
terminal
of
the
starting
motor.
If
the
starting
motor
is
not
equipped
with
a
negative
“
−
”
terminal,
connect
the
jump-start
cable
to
the
engine
block.
Check
the
electrical
wires
daily
for
wires
that
are
loose
or
frayed.
Tighten
all
loose
electrical
wires
before
the
engine
is
started.
Repair
all
frayed
electrical
wires
before
the
engine
is
started.
Refer
to
the
“Engine
Starting”
section
of
this
Operation
and
Maintenance
Manual
for
specific
starting
instructions.
Grounding
Practices
Proper
grounding
for
the
engine
electrical
system
is
necessary
for
optimum
engine
performance
and
reliability.
Improper
grounding
will
result
in
uncontrolled
electrical
circuit
paths
and
in
unreliable
electrical
circuit
paths.
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 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.
