Invalid Generator Management Enabled. The fault
lamp illuminates yellow and the alarm horn sounds
when the generator management has been disabled
because the generator management configuration of
this generator does not match the generator
management configuration of another generator that is
connected to the same PGEN network.
display shows Generator Management.
Invalid Genset Voltage Phase Connection. The fault
lamp illuminates yellow and the alarm horn sounds
when another generator in the paralleling system has a
different phase connection than this generator. The
local display shows System Phase.
Keep Battery On (IMO Tier III Models). The fault lamp
illuminates yellow and the alarm horn sounds to inform
the user to keep the battery power on the unit so the
ECM can run the afterrun cycle.
Low Aftertreatment1 Def Concentration (IMO Tier III
Models). The fault lamp illuminates yellow and the
alarm horn sounds to inform the user that the DEF
quality is low.
Low Battery Voltage. The fault lamp illuminates yellow
and the alarm horn sounds when the battery voltage
drops below a preset level for more than 90 seconds.

The low battery voltage feature monitors the battery and
battery charging system in the generator set operating
and off modes. The controller logic inhibits the low
battery voltage warning during the crank cycle.
Low Coolant Temperature. The fault lamp illuminates
yellow and the alarm horn sounds when the engine
coolant temperature is low.
temperature warning does not function during the preset
inhibit time delay period after startup.
Low Cranking Voltage. The fault lamp illuminates
yellow and the alarm horn sounds when the battery
voltage drops below 60% of the nominal voltage
(12 VDC or 24 VDC) for more than 6 seconds during the
crank cycle.
Low DEF Level (IMO Tier III Models). The fault lamp
illuminates yellow and the alarm horn sounds to inform
the user that they need to refill the DEF tank.

Low Engine Oil Level.
yellow and the alarm horn sounds because of low
engine oil level. This fault feature requires an optional
low engine oil level sensor for the lamp to function.
Low Fuel Level. The fault lamp illuminates yellow and
the alarm horn sounds when the fuel tank level on
diesel-fueled models approaches empty.
requires an optional low fuel level switch for the lamp to
function.
Low Fuel Pressure. The fault lamp illuminates yellow
and the alarm horn sounds when low fuel pressure
occurs. This fault requires an optional low fuel pressure
switch for the lamp to function.
Low Genset System Frequency.
illuminates yellow and the alarm horn sounds when
another generator in the paralleling system has a higher
system frequency than this generator. The local display
shows System Frequency, FMI: Low.
Low Genset System Voltage.
illuminates yellow and the alarm horn sounds when
another generator in the paralleling system has a higher
system voltage than this generator. The local display
shows System Voltage, FMI: Low.
Low Oil Pressure. The fault lamp illuminates yellow
and the alarm horn sounds when the engine oil pressure
approaches the shutdown range. The low oil pressure
warning does not function during first the 30 seconds
after startup.
Low Seawater Pressure (Heat Exchanger Model).
The fault lamp illuminates yellow and the alarm horn
sounds after a loss of seawater pressure is detected.
Option Board 2X Communication Loss. The fault
lamp illuminates yellow and the alarm horn sounds
when the communication with option board 2X (A, B, or
C) has been lost.
Reserve Oil Empty. The fault lamp illuminates yellow
and the alarm horn sounds when the oil makeup kit level
has dropped below a threshold.
Speed Sensor Fault. The fault lamp illuminates yellow
and the alarm horn sounds when the speed signal is
absent for one second while the generator set runs.
Total Reactive Power Low. The fault lamp illuminates
yellow and the alarm horn sounds when the generator has
a loss of field condition due to insufficient reactive load
production to support real load. The output breaker trips.
