Shutoffs
The shutoffs are electrically operated. The alarms are controlled by the control panel.The particular shutoff may need to be reset before the engine will start.The marine classification society control panel can be configured to override the shutdown or alarm.
Always determine the cause of the engine shutdown. Make necessary repairs before attempting to restart the 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:Coolant level - The low coolant level switch indicates when the coolant level is low.Coolant temperature - The coolant temperature sensor indicates high jacket water coolant temperature.Engine oil temperature - The engine oil temperature sensor indicates when the temperature is too high.Exhaust gas temperature - The exhaust gas sensor indicates when the temperature of the exhaust gas is too high.Filtered fuel delivery pressure - The filtered fuel delivery pressure measures fuel pressure.High-pressure fuel system leak detection - The high-pressure fuel system leak detection sensor detects fuel leaks.Intake manifold air temperature - The intake manifold air temperature sensor indicates high intake air temperature.Intake manifold pressure - The intake manifold pressure sensor checks the rated pressure in the engine manifold. Fuel rail pressure - The fuel rail pressure sensor checks for high pressure or low pressure in the fuel rail.Engine oil pressure - The engine oil pressure sensor indicates when oil pressure drops below rated system pressure, at a set engine speed.Engine overspeed - The primary speed/timing sensor checks the engine speed. Primary fuel filter deferential pressure - The primary fuel filter differential pressure sensor checks for the proper differential pressure.Sea water pressure - The sea water pressure sensor checks for low sea water pressure.Secondary fuel filter deferential pressure - The secondary fuel filter differential pressure sensor checks for the proper differential pressure.User-defined switch - This switch can shut down the engine remotely.Note: The sensing element of the coolant temperature switch must be submerged in coolant in order to operate.Engines may be equipped with alarms in order to alert the operator when undesirable operating conditions occur.
When an alarm is activated, corrective measures must be taken before the situation becomes an emergency in order to avoid possible engine damage.
If corrective measures are not taken within a reasonable time, engine damage could result. The alarm will continue until the condition is corrected. The alarm may need to be reset.Testing Alarms and Shutoffs
Alarms must function properly in order to provide timely warning to the operator. Shutoffs help to prevent damage to the engine. Determine if the engine protective devices are in good working order during normal operation is impossible. Malfunctions must be simulated in order to test the engine protective devices.
