Engine Shutdown Faults

Description The engine control module (ECM) continuously monitors vital engine functions for
fault conditions. When a fault condition occurs, the engine will shut down and the
LCD panel will display the fault causing the shutdown.
To reset the ECM and resume operation, return the Engine Start Switch manually
to off "O". Also refer to section Warning Light.

Description
Indicates that the emergency stop button has been
depressed. This display will remain on until the
emergency stop button is pulled back out.
Indicates that the engine coolant temperature has
exceeded 115°C (239°F) and the ECM has
automatically shut down the engine. Normal
engine running temperature is 85°C ± 8°C (185°F
± 15°F).
Indicates that the engine speed exceeded
approximately 1980 rpm (110% of its rated speed
of 1800 rpm) and the ECM has automatically shut
the engine down.
An overcrank fault is displayed when the engine
fails to start during three cycles of the normal
cranking cycle. The ECM has automatically shut
down the generator due to an overcrank condition.
A low fuel fault condition will be displayed when
the fuel tank drops to 5% and the ECM has shut
the engine down. This fault condition prevents the
fuel lines from running completely dry and avoids
the need to bleed the lines when the tank is
refilled.
The low fuel fault can be disabled if desired. See
Changing/Disabling Low Fuel Fault.
Indicates that the engine speed dropped below 55
Hz (1650 rpm) for more than 15 seconds and the
ECM has automatically shut the engine down.
Normal operating pressure is between
60–80 psi. If oil pressure drops below 15 psi, the
engine will automatically shut down.
For machines with the Low-Coolant Shutdown
Option only. This fault will be displayed when the
ECM has picked up a signal from the sensor that a
low-coolant level exists. During such a condition,
the ECM shuts the engine down.
