4.20 Engine Shutdown Faults
The Engine Control Module (ECM) continuously monitors vital engine functions for
seven 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.
4.20.1 EMERGENCY STOP
Indicates that the emergency stop button has been depressed. This
display will remain on until the emergency stop button is pulled back
out.
4.20.2 LOW OIL PRESSURE
Indicates that the engine oil pressure dropped below 1 bar (15 psi) and
the ECM has shut the engine down.
4.20.3 HIGH ENGINE TEMPERATURE
Indicates that the engine coolant temperature has exceeded 105°C
(221°F) and the ECM has automatically shut down the engine. Normal
engine running temperature is 85°C±8°C (185°F±15°F ).
4.20.4 OVERSPEED
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.
4.20.5 OVERCRANK
An overcrank fault is displayed when the engine fails to start after three
cycles of the normal cranking cycle, and the ECM has automatically
shut down the generator due to the overcrank condition.
4.20.6 LOW FUEL
A low fuel fault condition will be displayed when the fuel tank drops to
5% and the ECM has shut down the engine. 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.
4.20.7 UNDERSPEED
Indicates that the engine speed dropped below 55Hz (1650 rpm) for
more than 15 seconds and the ECM has automatically shut down the
engine.
