Figure 18 Low Battery Voltage Specs
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. The low coolant 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 Engine Oil Level. The fault lamp illuminates 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. This fault 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. The fault lamp 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. The fault lamp 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.
Not in Auto (Generator Master Control Switches). The fault lamp illuminates yellow and the alarm horn sounds when the
generator set button is in the RUN or OFF/RESET mode.
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.
