The EWPS includes the following features:
EWPS mode – This parameter indicates to the on-board electronics the desired mode of operation for the engine warning and protection feature.
Standard warning (rpm, ECT) – Engine overspeed and overheat are provided as the default operating mode. No engine shutdown is available.
2–way warning (rpm, ECT, EOP) – Engine overspeed, overheat, and low oil pressure are monitored in the engine warning operating mode. No engine shutdown is available.
3–way warning (rpm, ECT, EOP, ECL) – Engine overspeed, overheat, low oil pressure, and low coolant level are monitored in the engine warning operating mode. No engine shutdown is available.
3-way Protection (rpm, ECT, EOP, ECL) – Engine overspeed, overheat, low oil pressure, and low coolant level are monitored in the engine protection operating mode. Engine shutdown is available when a critical engine condition is detected. Critical engine conditions include overheat, low oil pressure and low coolant level.
ECT Warning Temperature – This parameter indicates when an engine overheat condition warrants the red ENGINE lamp to be illuminated and the warning buzzer to be activated.
ECT Critical Temperature – This parameter indicates when an engine overheat condition warrants an engine shutdown. The event logging feature will log when this event has occurred in both engine hours and odometer readings.
EOP RPM Boundary 1 – This parameter indicates the rpm range that engine oil pressure level 1 is used for
the loss of engine oil pressure detection.
EOP RPM Boundary 2 – This parameter indicates the rpm range that engine oil pressure level 2 is used for
the loss of engine oil pressure detection.
EOP RPM Boundary 3 – This parameter indicates the rpm range that engine oil pressure level 3 is used for
the loss of engine oil pressure detection.
EOP Warning Level 1 – This parameter indicates when a loss of engine oil pressure warrants the red ENGINE lamp to be illuminated and the warning buzzer to be activated.
EOP Warning Level 2 – This parameter indicates when a loss of engine oil pressure condition warrants the red ENGINE lamp to be illuminated and the warning buzzer to be activated.
EOP Warning Level 3 – This parameter indicates when a loss of engine oil pressure condition warrants the red ENGINE lamp to be illuminated and the warning buzzer to be activated.
EOP Critical Level 1 – This parameter indicates when a loss of engine oil pressure condition warrants an
engine shutdown. The event logging feature will log when this event has occurred in both engine hours and
odometer readings.
EOP Critical Level 2 – This parameter indicates when a loss of engine oil pressure condition warrants an
engine shutdown. The event logging feature will log when this event has occurred in both engine hours and odometer readings.
EOP Critical Level 3 – This parameter indicates when a loss of engine oil pressure condition warrants an engine shutdown. The event logging feature will log when this event has occurred in both engine hours and odometer readings.
