Low Oil Pressure. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down because of low oil pressure.
The shutdown occurs 5 seconds after the low pressure condition is detected. The low oil pressure shutdown does not function
during first the 30 seconds after startup.
Low Seawater Pressure. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down after a loss of seawater
pressure is detected.
Max. Alternator Current Low. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down when Alternator
Protection Configuration in the personality profile is not correct. If the settings are correct for the application, the controller may
need a new or updated personality profile. Consult your local authorized distributor.
Oil Pressure Open Circuit. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down when the engine oil
pressure sender circuit is open for more than 5 seconds.
Overcrank. The fault lamp illuminates red, the alarm horn sounds, and cranking stops when the unit does not start within the
defined cranking period. See the Controller Operation section for cyclic crank specifications.
Note:
The controller is equipped with an automatic restart function. When speed drops below 25 Hz (750 rpm) while the engine is
running, the unit attempts to recrank. The unit then follows the cyclic cranking cycle and, when the engine fails to start, will shut
down on an overcrank fault condition.
Run Relay Coil Overload. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down when the current
draw on the 70 wire from the controller has exceeded 40 amps or has exceeded 10 amps for at least 10 ms.
Starter Relay Coil Overload. The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down when the current
draw on the 71 wire from the controller has exceeded 40 amps or has exceeded 10 amps for at least 10 ms.
Trip to Shutdown Delay The fault lamp illuminates red, the alarm horn sounds, and the unit shuts down when the generator is
stopped if the circuit breaker has tripped for a Protective Relay function, and the trip to shutdown time delay has expired. This
delay allows mitigation of problem conditions without engine shutdown. If the delay expires, it is presumed no successful action
was taken in the allotted time.
2.14.5 Status and Notice Digital Displays
Warnings and shutdown faults appear on the digital display under the Active Events menu and become part of the event history.
Beyond the warnings and shutdowns there are several events which also appear on the digital display under the Active Events
menu. Status is an event that is not an alert but is part of the event history. Notice is an alert that is not part of the event history.
The controller allows a selected number of changes by the user for setting up the controller application which are covered in this
section.
Alarm Horn Silence. This status message indicates whether the alarm horn can be silenced in any button mode (OFF/RESET-
AUTO-RUN) or requires the AUTO button be pressed first compliant per NFPA 110. Use SiteTech™ software to change this
setting. See the Controller Resetting (Following System Shutdown or Warning) section, Controller Resetting procedure, for
information on resetting the system.
The local display shows Alarm Silence: Always when the alarm horn can be silenced with the master control buttons in any
position (default setting).
The local display shows Alarm Silence: Auto Only when the alarm horn can be silenced only when in the AUTO mode. The
correct reset sequence requires pressing the OFF/RESET button, then pressing the AUTO button, and then pressing the ALARM
SILENCE button.
Close Breaker. This notice message indicates that the controller is attempting to close the circuit breaker (a close command is
being sent to the circuit breaker). This notice only appears in paralleling applications (where the bus sensing is connected to the
bus side of the paralleling breaker).
Contactor. This notice message indicates that the controller wants to be connected to the paralleling bus. If a contactor is used
for paralleling, this output controls it. This notice only appears in paralleling applications (where the bus sensing is connected to
the bus side of the paralleling breaker).
Emergency Power System (EPS) Supplying Load. This notice message indicates when the generator set supplies more than
1% of the rated standby output current.
