Condition
The LOP switch indicates low oil pressure for more than 5
seconds. Function becomes active 30 seconds after crank
disconnect (30 second inhibit).

recommended in Section 4.
The fuel pressure switch measures low fuel pressure (below
4.5 inches water column). (Optional communications kit
required.)
Engine speed exceeds 115% of the normal running speed for
more than 0.3 seconds.
Exercise not scheduled. No exercise is scheduled on the
controller.
Generator voltage high. Output voltage exceeds 120% of the
system nominal voltage for more than 2 seconds.

more than 6 seconds while the starter is engaged.
No engine rotation is sensed during cranking. Shuts down 3
seconds after the fault is detected.
