Alarms and shutoffs are electronically controlled. The operation of all alarms and shutoffs utilizes components which are actuated by a sensing unit. The alarms and shutoffs are set at critical operating temperatures, pressures, or speed to protect the engine from damage.
The alarms function to warn the operator when an abnormal operating condition occurs. The shutoffs function to shut down the engine when a more critical abnormal operating condition occurs. The shutoffs help to prevent damage to the equipment.
If an engine protective device shuts off the engine, always determine the cause of the shutoff. Make the necessary repairs before attempting to start the engine.
Become familiar with the following information:
- Types of the alarm and shutoff controls
- Locations of the alarm and shutoff controls
- Conditions which cause each control to function
- Resetting procedure that is required before starting the engine
For information about the specific alarms and shutoffs for the engine, refer to the Troubleshooting Guide .
