System Status Lamps; System Fault Warning Lamp With Digital Displays - Kohler Industrial Generator Set Operation Manual

2.4.4

System Status Lamps

The (OFF/RESET--AUTO--RUN) master control buttons
indicate the status condition with an integrated lamp at
the button.
The green lamp illuminates on the master control AUTO
(automatic start) button indicating the system senses no
faults and the unit is ready to start by remote command.
The red lamp illuminates on the master control
OFF/RESET button indicating the generator set is
stopped.
The yellow lamp illuminates on the master control RUN
button indicating the generator set is cranking or running
from a local command.
Only one of the three master control button lamps will
illuminate at any given time.
2.4.5 System Fault Warning Lamp with
Digital Displays
The system FAULT lamp glows yellow and the alarm
horn sounds indicating a warning fault but does not shut
down the generator set. 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. The local display shows Fuel Level
Low Warning. See Section 2.4.8, Controller Resetting
procedure, for instructions on resetting a system
warning.
When the system warning lamp is on and no message
displays, rotate the selector dial to view messages.
When the system warning continues, it may lead to a
fault and cause a system shutdown.
Use the Silence Alarm button to silence the alarm horn
at the operator's discretion.
If the controller is setup for an NFPA 110 application,
press the AUTO button before silencing the alarm horn.
The alarm horn cannot be silenced unless the master
control button is in the AUTO mode. See 2.4.7 Status
and Notice Digital Displays for more information.
Note: Text shown in italics in this section of the manual
represents digital display messages.
38 Section 2 Operation
AC Sensing Loss. The fault lamp illuminates yellow
and the alarm horn sounds when the controller does not
detect the nominal generator set AC output voltage after
crank disconnect. The controller displays AC Sens Loss
Warning.
Auxiliary Input (Warning). The fault lamp illuminates
yellow and the alarm horn sounds when an auxiliary
digital or analog input signals the controller. The digital
inputs do not function during first the 30 seconds after
startup. Use SiteTecht software to define inputs as
shutdowns or warnings. The local display shows Aux
Input Warning.
Battery Charger Communication Loss. The warning
fault lamp on the controller illuminates yellow and the
alarm horn sounds when CAN communication with the
battery charger has been lost. Local display shows
either bat1CommLoss or bat2CommLoss.
Note: bat2CommLoss indicates communication loss
for battery charger number 2. bat2CommLoss is
only relevant for generator sets with more than
one battery charger.
Battery Charger Fault. The warning lamp on controller
illuminates yellow and the alarm horn sounds when the
battery charger malfunctions. Local display shows Batt
Chg Flt.
Battery Charger Identity Conflict. The warning lamp
on the controller illuminates yellow and the alarm horn
sounds when there is a CAN address communication
error. The battery charger has the same CAN address
as another generator set component. To correct a CAN
address error, verify the address identification in the
harness and power cycle the controller. Local display
shows BatIdErr.
Battery Charger Parameter Mismatch. The warning
lamp on controller illuminates yellow and the alarm horn
sounds when the battery charger metering is not in
range of the specified parameters. Local display shows
ParMisatch.
Battery Fault. The warning lamp on controller
illuminates yellow and the alarm horn sounds when
there is an issue with the battery such as a connection
problem or a dead battery. When the temperature
compensation sensor is connected, whether active or
inactive, and the temperature rises above 60_C (140_F)
or below --20_C (--4_F), the battery failure warning will
also be displayed indicating that the battery is unable to
take charge due to temperature. Absorption timeout will
also cause a failure since the battery was unable to
accept the expected charge in the time frame given
which indicates a potential battery issue. Local display
shows Battery Flt.
