2.14.2 System Status Lamps
The (OFF/RESET-AUTO-RUN) buttons indicate the status condition with an integrated lamp at the button.
The lamp illuminates on the AUTO (automatic start) button indicating the system senses no faults and the unit is ready to start
by remote command.
The lamp illuminates on the OFF/RESET button indicating the generator set is stopped.
The lamp illuminates on the RUN button indicating the generator set is cranking or running from a local command or is
commanded to run from a local command.
Only one of the three button lamps will illuminate at any given time.
2.14.3 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. See the Controller Resetting (Following
System Shutdown or Warning) section, for instructions on resetting a system warning.
When the system warning lamp is on and no message displays, rotate the dial to the Active Events menu. Press the dial to view
messages. Rotate the dial to view additional messages. Press the OFF button to return to the main menu. 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 button is in the AUTO mode. See Status and Notice Digital Displays section for more information.
AC Sensing Lost (controller in RUN or AUTO and voltage was never present). 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.
Auxiliary Input. 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 the first 30 seconds after startup. Use SiteTech™ software to define
inputs as shutdowns or warnings.
Average Current High. The fault lamp illuminates yellow and the alarm horn sounds when the generator encounters excessive
load or a downstream fault. The output breaker trips. The available sustained fault current of the generator can be obtained from
the per-unit transient reactance of the generator and the system voltage and power.
Average Generator Voltage High. The fault lamp illuminates yellow and the alarm horn sounds when the generator encounters
an over voltage condition. This condition can be caused by a loss of sensing wire, a winding failure, voltage regulator failure,
etc. The output breaker trips. The generator may continue to produce excessive voltage until it is shut down.
Average Generator Voltage Low. The fault lamp illuminates yellow and the alarm horn sounds when the generator encounters
an under voltage condition. This condition can be caused by a loss of a diode on the rectifier bridge, sensing problem, a winding
failure, voltage regulator failure, etc. The output breaker trips. The generator may continue to produce insufficient voltage until it
is shut down.
Battery Charger Fault. The fault lamp illuminates yellow and the alarm horn sounds when the battery charger malfunctions.
This fault feature requires an optional battery charger with a malfunction output for the lamp to function.
Cabinet Intrusion. The fault lamp illuminates yellow and the alarm horn sounds when the door to the unit was opened.
Common Warning. The fault lamp illuminates yellow and the alarm horn sounds when the controller is signaled by a common
warning. Use SiteTech™ software to activate the common warning. The common warning comprises all of the warnings under
a single alert.
Critically High Fuel Level (diesel-powered models only). The fault lamp illuminates yellow and the alarm horn sounds when
the fuel tank level on diesel models approaches full. This fault requires an optional critical high fuel switch and fuel tank for the
lamp to function.
ECM Diagnostics (Multiple Engine Inputs). The fault lamp illuminates yellow and the alarm horn sounds when ECM
diagnostics signals the controller. The specific display (xxxxx) will be a brief message or fault code that is engine manufacturer
dependant. The engine literature provides the fault code description and further information.
