5.6 Alarms and Shut-Down Conditions – DeepSea
Background
The Light Tower controller monitors variables of engine and machine function. The
Light Tower controller has two types of alarms: warning alarms and shut-down
alarms.
Warning
alarms
Warnings are non-critical alarm
conditions that do not affect the operation
of the generator system. They serve to
draw the operator’s attention to an
undesirable condition. Warning alarms
are self-resetting when the fault condition
is removed.
Warning alarms include:
a.Generator over-frequency
b.Generator under-frequency
c. Time to maintenance-oil
d.Time to maintenance-air filter
e.Time to maintenance-fuel filter
During a warning alarm condition, the
LCD panel displays the type of warning
alarm. The machine is not shut down.
Shut-down
alarms
Shut-down alarms are latching alarms
and stop the generator. Shut-down
alarms include:
f. High coolant temperature
g.Low oil pressure
h.Overspeed
i. Underspeed
j. Generator over-frequency
k. Generator under-frequency
l. Overcrank
m.Low coolant level (if equipped)
n.Emergency stop
During a shut-down alarm condition, the
LCD panel displays the type of alarm that
caused the machine shutdown. Remove
the fault condition, then press “Stop”.
