Hi Cool Temperature Alarm - Threshold (Deg F). This setting selects the coolant temperature that will trigger
a high coolant temperature alarm. A threshold setting of 100 to 280 degrees Fahrenheit or 38 to 138 degrees
Celsius may be entered. A 60 second activation delay prevents a Hi Coolant Temperature Alarm from
occurring at engine startup.
Hi Cool Temperature Alarm - Arming Delay (Sec). This read-only setting displays the time delay between
when high coolant temperature is detected and an alarm is annunciated and the engine is shut down. The
arming delay is fixed at 60 seconds.
Low Oil Pressure Alarm - Alarm Enable. This setting enables and disables annunciation of a low oil pressure
alarm and engine shutdown. A 10 second activation time delay prevents low oil pressure annunciation during
engine startup.
Low Oil Pressure Alarm - Threshold (PSI). This setting selects the oil pressure level that will trigger a low oil
pressure alarm and engine shutdown. A threshold of 3 to 150 psi or 20 to 1,035 kPa may be entered. A 10
second activation time delay prevents low oil pressure annunciation during engine startup.
Low Oil Pressure Alarm - Arming Delay (Sec). This setting selects the time delay between when low oil
pressure is detected and an alarm is annunciated and the engine is shut down. A time delay of 5 to 15
seconds may be entered. A 10 second activation time delay prevents low oil pressure annunciation during
engine startup.
Low Fuel Level Alarm - Alarm Enable. This setting enables and disables alarm annunciation and engine
shutdown for a low fuel level.
Low Fuel Level Alarm - Threshold (% Full Tank). This setting selects the fuel level that will trigger a low fuel
level alarm. A threshold of zero to 100 percent may be entered.
Overspeed-Sender Fail Tab
The Overspeed-Sender Fail Tab settings are shown in Figure 4-12. Each tab setting is described in the
following paragraphs.
Overspeed Alarm - Alarm Enable. This setting enables and disables alarm annunciation and engine shutdown
for an overspeed condition.
Overspeed Alarm - Threshold (% of Rated). This setting selects the percentage of overspeed that triggers an
overspeed alarm and engine shutdown. The threshold is adjustable from 105 to 140 % of nominal speed.
