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 the section titled: 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 the section titled: Status and Notice Digital
Displays for more information.
Note:
Text shown in italics in this section of the manual represents digital display messages.
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 SiteTech™ 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.
