2.7.2 Starting the Generator Set
The following procedures describe starting the
generator set.
Local Starting. Move the generator set to the RUN
position to immediately start the generator set.
Auto (Automatic) Starting. Move the generator set
master switch to the AUTO position to allow startup by
the automatic transfer switch or the remote start/stop
switch (connected to controller terminals TB1-3 and
TB1-4).
Note: The controller provides up to 30 seconds of
continuous cranking before overcrank shutdown
occurs.
2.7.3 Stopping the Generator Set
The following procedure describe how to stop the
generator set.
Normal Stopping
1. Cooldown. Run the generator set at no load for
5 minutes to ensure adequate engine cooldown.
2. Stopping. Move the generator set master switch
to the OFF/RESET position. The engine stops.

2.7.4 Fault Shutdowns
The generator set shuts down automatically under the
following fault conditions and cannot be restarted until
the fault condition is corrected. The system automatically
resets when the problem is corrected or the generator
set cools (if high engine temperature was the fault).
The fault lamp does not stay lit after the generator set
shuts down on a fault condition.
Fault Description
High engine
temperature
Shutdown occurs 5 seconds after the
fault. The high engine temperature
shutdown does not function during the
first 5 seconds after startup.
Note: The high t emperature
shutdown functions only when the
coolant level is in the operating range.
High exhaust
temperature
Shutdown occurs 5 seconds after the
fault. The high exhaust temperature
shutdown does not function during the
first 5 seconds after startup.
Low coolant level Shutdown occurs 5 seconds after the
fault. The low coolant level shutdown
does not function during the first
5 seconds after startup.
Low oil pressure Shutdown occurs 5 seconds after the
fault. The low oil pressure shutdown
does not function during the first
5 seconds after startup.
Note: The low oil pressure shutdown
does not protect against low oil level.
Check the oil level at the engine.
Overcrank Shutdown occurs after 30 seconds of
continuous cranking. Shutdown
occurs after 30 seconds if the engine
or starter does not turn (locked rotor).
Overspeed Shutdown occurs immediately when
the governed frequency on the 50 and
60 Hz models exceeds 70 Hz.

2.7.5 Controller Resetting Procedure
(Following Fault Shutdown)
Use the following procedure to restart the generator set
after a fault shutdown.
1. Disconnect the generator set from the load using
the line circuit breaker or automatic transfer switch.
See the Safety Precautions at the beginning of this
section before proceeding.
2. Correct the cause of the fault shutdown. See the
Safety Precautions at the beginning of this section
before proceeding.
3. Start the generator set by moving the generator set
master switch to RESET/OFF and then to RUN.
4. Verify that the cause of the shutdown has been
corrected by test operating the generator set.
5. Reconnect the generator set to the load using the
line circuit breaker or automatic transfer switch.
6. Move the generator set master switch to the AUTO
position for startup by remote transfer switch or
remote start/stop switch.
