Shutoffs
The shutoffs are electrically operated or mechanically operated. The electrically operated shutoffs are controlled by the ECM.Shutoffs are set at critical levels for the following items:
Operating temperature
Operating pressure
Operating level
Operating rpmThe particular shutoff may need to be reset before the engine will start.
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 engineAlarms
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 in order to illuminate the lamp.Your engine may be equipped with the following sensors or switches:Coolant temperature - The coolant temperature sensor indicates high jacket water coolant temperature.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 measures the high pressure or low pressure in the fuel rail. The ECM will Check the pressure.Engine oil pressure - The engine oil pressure sensor indicates when oil pressure drops below rated system pressure, at a set engine speed.Engine overspeed - If, the engine rpm exceeds the overspeed setting the alarm will be activated.Air filter restriction - The switch checks the air filter when the engine is operating.User-defined switch - This switch can shut down the engine remotely.Water in fuel switch - This switch checks for water in the primary fuel filter when the engine is operating.Fuel temperature - The fuel temperature sensor monitors the pressurized fuel in the high-pressure fuel pump.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.Note: If installed, the coolant level switch and the oil level switch are indicators. Both switches operate when the application is on level ground and the engine RPM at zero.Clean Emission Module (CEM)
Diesel Oxidation Catalyst ____________________(DOC)
Selective Catalyst Reduction ____________________ (SCR)Soot Sensors - The soot sensors monitor the soot level within the CEMNOx Sensors - Two NOx sensors monitor the NOx concentration within the exhaust gas before and after the selective catalyst reduction module. Temperature Sensors - A temperature sensor after the engine exhaust gas exit, after the DOC and before the SCR module monitor the temperatures within the system.Pump Electronics
