Features and Controls
Alarms and Shutoffs
Shutoffs
The shutoffs are electrically operated or mechanically
operated. The electrically operated shutoffs are
controlled by the Electronic Control Module (ECM).
Shutoffs are set at critical levels for the following
items:
• Coolant operating temperature
• Oil operating pressure
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 shutoff
• Conditions which cause each shutoff to function
• The resetting procedure that is required to restart
the engine
Alarms
NOTICE
When an alarm is activated, corrective measures
must be taken before the situation becomes an emer-
gency in order to avoid possible engine damage.
The alarms are electrically operated. The operations
of the alarms are 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 to illuminate the
lamp.
Your engine may be equipped with the following
sensors or switches:
Fuel rail pressure – The fuel rail pressure sensor
measures the high pressure or low pressure in the
fuel rail. The ECM will Check the pressure.
Engine oil pressure – The engine oil pressure
switch indicates when oil pressure drops below rated
system pressure, at a set engine speed.

Coolant temperature – The coolant temperature
sensor indicates high jacket water coolant
temperature.
Gauges and Indicators
Your engine may not have the same gauges or all 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 dealer
or 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.
with SAE10W30 is 207 kPa to 413 kPa
(30 psi to 60 psi) at rated rpm.
A lower oil pressure is normal at low idle. If the load is
stable and the gauge reading changes, perform the
following procedure:
1. Remove the load.
2. Reduce engine speed to low idle.
3. Check and maintain the oil level.
allowable temperature with the pressurized
cooling system at 90 kPa (13 psi) is 112° C
(233.6° F). Higher temperatures may occur under
certain conditions. The water temperature
reading may vary according to load. The reading
should never exceed the boiling point for the
pressurized system that is being used.
NOTICE
Engine Oil Pressure – The oil pressure
should be greatest after a cold engine is
started. The typical engine oil pressure
Jacket Water Coolant Temperature –
Typical temperature range is 82° to 96°C
(147.6° to 172.8°F). The maximum
