Protective Diagnostics and
their description
Differential Oil Pressure Overdue
is a latching diagnostic that can
come up while the unit is in pre-
lube.
The differential pressure switch
status is used instead of the Low
Differential Oil Pressure Cutout
setpoint.
Low Differential Pressure Cutout
is a latching diagnostic that can
come up while the unit is
running. Oil pressure is
indicative of oil flow and active
oil pump operation. Significant
fall in oil pressure is indicative of
failure of the oil pump, oil
leakage, or other blockage in the
oil circuit.
Once oil flow has been
established, if the differential
pressure switch indicates there
is not oil pressure for 2 seconds,
this diagnostic will be issued.
Unexpected Differential Oil
Pressure
is a latching diagnostic
that can come up while the unit
is idle and is implemented to
recognize and ensure that the
pressure switch is operational
and that it is open for a period of
five minutes.
