Description
Lost J1939 CAN bus
communications with MotorTech
Throttle Module.
The user can enable shutdown
bypass if the generator is
required to provide critical
support through a generator
alarm. This warning indicates the
generator is currently running
with or ready to run with the
shutdown bypass feature
enabled.
To provide critical support, a real
alarm or warning occurred but
was bypassed while shutdown
bypass was active. The Display
will log the alarm sensed by the
generator, but the generator will
not shut down because of the
alarm.
Transfer switch open during a
baseload operation.
No Baseload communications
within designated time.
The "Dual Fuel" option is selected
as Fuel Type, but the Dual Fuel
settings have not been
configured. When Dual Fuel is
selected as the Fuel Type, the
following items must be
configured: the type of dual fuel
sensor, alarm settings for the
sensor, and the input channels for
the sensor.

communications
between the Main
Controller and the

shutdown alarm using
the Display.
To clear the alarm,
disable the shutdown

the Display.
Record the alarm noted
by the Display. Take
appropriate action to
resolve the alarm. Clear
the alarm using the
Display.
Baseload switch still
open can be cleared by
acknowledging or by the
generator synching and
closing its switch.
Baseload Comms loss
can be cleared by either

setting under Air Fuel
Setup in the Display and
correct the setting to the
appropriate fuel type. If it
is dual fuel, go to the
Dual Fuel Setup screen
on the Display and
complete the setup for
the dual fuel sensor.
