The system is fail-safe, because breakage of an oil pres-sure line, excessive oil leakage, or a plugged orifice will cause engine shutdown.

● Master Shutdowns must be latched in run position to start engine.
● Engine oil pressure arms the Master Shutdown device.
● Sensors vent oil tripping the spring actuated Mas-ter Shutdown device.
● Loss of engine oil pressure causes shutdown.

VENT TO SHUTDOWN PRINCIPLE

In a typical system, engine lubricating oil is fed through an orifice to High Jacket Water Temperature valve 2230, then to Water Pump Differential Pressure valve 4143, then to Overspeed valve 4110. All sensors except the master shut-down device vent oil back to the crankcase when they are tripped.

If, for example, engine water temperature exceeds the trip setting, the 2230 vents the oil between the 2185 orifice and the 2800 Safety Control back to the sump. The function of the orifice is to restrict the lubricating oil that is feeding the safety system so that the venting device will positively drop pressure at the 2800, causing it to shut down the engine.

As many sensors can be used on an engine as needed.
