Alarms and Shutoffs
Engine Shutoffs
The shutoffs are electrically operated or mechanically
operated. The electrically operated shutoffs are
controlled by the ECM.
Shutoffs are set at critical levels for the following
items:
•
Operating temperature
•
Operating pressure
•
Operating level
The particular shutoff may need to be reset before
the engine will start.
NOTICE
Always determine the cause of the engine shutdown.
Make necessary repairs before attempting to restart
the engine.
Be familiar with the following items:
•
Types and locations of the shutoff
•
Conditions which cause each shutoff to function
•
The resetting procedure that is required to restart
the engine
Engine Alarms
The alarms are electrically operated. The operation
of the alarms is controlled by the ECM.
The alarm is operated by a sensor or by a switch.
When the sensor or the switch is activated, a signal
is sent to the ECM. An event code is created by
the ECM. The ECM will send a signal in order to
illuminate the lamp.
Your engine may be equipped with the following
sensors or switches:
•
Engine oil temperature sensor
•
Engine oil pressure sensor
•
Engine coolant temperature sensor

Gauges and Indicators
Your engine may not have the same gauges or all of
the gauges that are described. For more information
about the gauge package, see the OEM information.
Gauges provide indications of engine performance.
Ensure that the gauges are in good working order.
Determine the normal operating range by observing
the gauges over a period of time.
Noticeable changes in gauge readings indicate
potential gauge or engine problems. Problems may
also be indicated by gauge readings that change
even if the readings are within speci
fi
cations.
Determine and correct the cause of any signi
fi
cant
change in the readings. Consult your Perkins
distributor for assistance.
NOTICE
If no oil pressure is indicated, STOP the engine. If
maximum coolant temperature is exceeded, STOP
the engine. Engine damage can result.
Engine Oil Pressure –
The engine oil
pressure at idle is 103 kPa (15 psi).
•
The 1600A oil pressure at full load can range
between 340 to 360 kPa (49 to 52 psi)
•
The 1600D oil pressure at full load operates at
370 kPa (53 psi)
Jacket Water Coolant Temperature –
Typical water temperature into the engine
is 88° to 109°C (190° to 228°F). Higher
temperatures may occur under certain conditions.
The water temperature reading may vary according
to load. The reading should never exceed 109° C
(228° F).
1.
A high water temperature switch is installed in the
cooling system.
Tachometer –
This gauge indicates engine
speed (rpm).
Ammeter –
This gauge indicates the
amount of charge or discharge in the
battery charging circuit. Operation of the
indicator should be to the right side of “0” (zero).
