Fault Shutdowns
Code Description
Frequency Underfrequency
Low shutdown occurs
Shutdown when the
governed
frequency falls
below the default
setting of the
system's
frequency setpoint.
Locked Overcrank (locked
Rotor rotor) shutdown
Shutdwn
Oil Pres Low Low oil pressure
Shutdwn shutdown occurs if
a low oil pressure
condition exists.
Note: The low oil
pressure shutdown
does not protect
against low oil
level. Check the
oil level at the
engine.
Over Crank Overcrank
Shutdwn shutdown occurs
after 3
unsuccessful
starting attempts.
Sea Pressur Low seawater
Low pressure
Shutdwn shutdown occurs
after a loss of
seawater
pressure is
detected.
Volts xx--xx Overvoltage
High shutdown occurs if
Shutdwn the voltage
exceeds the
default setting of
the voltage
regulator setpoint.
Volts xx--xx Undervoltage
Low shutdown occurs
Shutdwn if the voltage falls
below the default
setting of the
voltage regulator
setpoint.
