Overspeed Alarm - Alarm Activation (MilliSecond). This setting adjusts the time delay from when an overspeed
alarm condition is detected until it is annunciated and the engine is shut down. A time delay of zero to 500
milliseconds may be entered.
Sender Failure Alarm - Cool Temp. Send Fail Alarm. This setting enables and disables alarm annunciation
and engine shutdown for a coolant temperature sender failure.
Sender Failure Alarm - Coolant Temp Alarm Delay. This setting adjusts the time delay from when a coolant
temperature sender failure is detected until it is annunciated and the engine is shut down. A time delay of 5,
10, 15, 20, 25, or 30 minutes may be selected.
Sender Failure Alarm - Oil Press. Sender Fail Alarm. This setting enables and disables alarm annunciation
and engine shutdown for an oil pressure sender failure. An oil pressure sender failure alarm is annunciated
and engine shutdown is initiated when the Global Sender Failure Alarm Time Delay expires.
Sender Failure Alarm - Loss of Gen. Voltage Alarm. This setting enables and disables alarm annunciation and
engine shutdown for a loss of generator voltage. A loss of generator voltage alarm is annunciated when the
generator voltage decreases below 1.5 Vac and the Global Sender Failure Alarm Time Delay expires. This
setting does not disable a Sender Failure Alarm for the speed signal source when generator frequency is
selected as the speed signal source.
Sender Failure Alarm - Global Sender Failure Alarm Time Delay (Sec). This setting selects the time delay
between when an oil pressure sender failure, loss of generator voltage failure, or MPU sender failure is
detected and alarm annunciation and engine shutdown.
