There are three primary modes of operation, selected by
pressing the respective buttons:
OFF
D
RUN
D
AUTO (Standby Mode)
D
When the OFF button is pressed, the generator set is in
OFF or goes to OFF and will not start. When the RUN
button is pressed, the generator set starts and runs until
the OFF or AUTO button is pressed or until a fault is
received. When the AUTO button is pressed, the
generator set enters
(STANDBY-RUNNING or STANDBY-OFF depending
upon the start signal).
OFF. If the generator set was previously running,
D
pressing the OFF button immediately shuts off the
generator set, with no engine cooldown.
generator set remains off and will not respond to a
remote start signal.
RUN—Local Start. A single generator set starts. No
D
other generator sets in the system will start (or stop).
AUTO—Standby or System Ready. The generator
D
set is waiting for a start signal. The generator set will
start and run when a start signal is received via a
remote start, local auto-start, or communications-
based start.
All generator sets in the system (connected by PGEN
and in Standby Mode by pressing AUTO) will start
when any one of the generator sets receives a start
signal.
Any generator set in the system not in AUTO will not
start.
If Generator Management is on, some generator sets
may shutdown after a period of time.
With removal of the start signal, all generator sets will
shutdown with the appropriate engine cooldown.
AUTO-RUN (Press AUTO and RUN together for a
D
system start signal). All generator sets in the system
start and run, close to bus, synchronize, parallel,
share load, etc. Some generator sets may shut down
after a period of time (indicated by Generator
Management) but they remain in Standby Mode
ready to start and run if needed.
AUTO-OFF (Press AUTO and OFF together to
D
remove a system start signal, if AUTO-RUN is active).
All generator sets in the system open their breakers,
enter engine cooldown, shut down, and enter Standby
Mode. Closing the remote start contacts has no affect.
Generator sets in the system will enter Standby Mode.

Note: Pressing AUTO and OFF together only
stops the generator sets if there are no other
system start signals present.
Start Signal
A start signal includes the following:
Remote start signal via contacts 3 and 4. An ATS
D
(used during a power outage, exercise period, etc.) or
a remote panel used in the vessel take precedence
over all other start signals.
System Start (AUTO-START).
D
RUN simultaneously to send a start signal.
Communications-based
D
SiteTecht or a CAN-based remote panel.
Hardwired contacts (remote start contacts 3 and 4) have
priority over all other start signals. If the remote start
contacts are activated, the generator sets in the system
that are in AUTO, will start and run. If the generator sets
were already running, they will remain running but the
original source of that start signal will be ignored. The
contacts now have control.
Note: The transient start/stop function of the controller
prevents accidental cranking of the rotating engine.
The generator set stops and recranks when the
OFF/RESET button is momentarily pressed and
then the RUN button is pressed.
Note: The controller provides up to 30 seconds of
programmable cyclic cranking and up to
60 seconds rest with up to 6 cycles. The default
setting is 15 seconds cranking and 15 seconds
rest for 3 cycles. Make cyclic cranking
adjustments using SiteTecht software.
