Alarms and Shutoffs
The alarm is a warning to the operator that an
abnormal operating condition has occurred. The
shutoffs are set in order to protect the engine from
damage. A shutoff can be triggered by pressure,
temperature, engine speed, and electronic fault.
The operator should become familiar with the
warning lamps and shutdown lamps on the installed
control panel before operating the application. For
more information refer to this Operation and
Maintenance Manual, “Monitoring System (Table for
the Indicator lamps)”.

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.
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.
Some engine applications are equipped with
Indicator Lamps. Indicator lamps can be used as a
diagnostic aid. There are two lamps. One lamp has
an orange lens and the other lamp has a red lens.
These indicator lamps can be used in two ways:
• The indicator lamps can be used to identify the
current operational status of the engine. The
indicator lamps can also indicate that the engine
has a fault. This system is automatically operated
via the ignition switch.
• The indicator lamps can be used to identify active
diagnostic codes. This system is activated by
pressing the Flash Code button.
Refer to the Troubleshooting Guide, “Indicator
Lamps” for further information.
Jacket Water Coolant Temperature –
Typical temperature range is 79° to 94°C
(174° to 201 °F). This temperature range
will vary according to engine load and the
ambient temperature.
A 100 kPa (14.5 psi) radiator cap must be installed
on the cooling system. The maximum temperature for
the cooling system will depend on engine power. For
engines that are 75kW and lower the maximin cooling
temperature is 110° C (230° F). For engines that are
above 75kW the maximin temperature is 108° C
(226.4° F). The engine coolant temperature is
regulated by the engine sensors and the engine
ECM. This programming cannot be altered. An
engine derate can occur if the maximum engine
coolant temperature is exceeded.
If the engine is operating above the normal range,
reduce the engine load. If high coolant temperatures
are a frequent event, perform the following
procedures:
1. Reduce the load and the engine rpm.
2. Determine if the engine must be shut down
immediately or if the engine can be cooled by
reducing the load.
3. Inspect the cooling system for leaks. If necessary,
consult your Perkins distributor for assistance.
Tachometer – This gauge indicates
engine speed (rpm). When the throttle
control lever is moved to the full throttle
position without load, the engine is running at
high idle. The engine is running at the full load
rpm when the throttle control lever is at the full
throttle position with maximum rated load.
NOTICE
To help prevent engine damage, never exceed the
high idle rpm. Overspeeding can result in serious
damage to the engine. Operation at speeds exceed-
ing high idle rpm should be kept to a minimum.
Ammeter – This gauge indicates the
amount of charge or discharge in the
battery charging circuit. Operation of
the indicator should be to the ““+”” side of ““0””
(zero).
Fuel Level – This gauge indicates the
fuel level in the fuel tank. The fuel level
gauge operates when the ““START/STOP””
switch is in the ““on”” position.
Service Hour Meter – The gauge
indicates total operating hours of the
engine.
