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

i04266770
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 specifications.
Determine and correct the cause of any significant
change in the readings. Consult your Perkins
distributor for assistance.
If no oil pressure is indicated, STOP the engine. If
maximum coolant temperature is exceeded, STOP
the engine. Engine damage can result.
•
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)
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.
indicator should be to the right side of "0" (zero).
