MANUAL
•Will not transfer to generator if utility is present.
•Will transfer to generator if utility fails (below 65% of nominal for 10 consecutive seconds).
•Will transfer back when utility returns for 15 consecutive seconds. The engine will continue to
run until removed from the MANUAL mode.
AUTO
•Will start and run if utility fails (below 65% of nominal for 5 consecutive seconds).
•Will start a 6 second engine warm-up timer (or 30 seconds; refer to Cold Smart Start).
–Will not transfer if utility subsequently returns.
–Will transfer to generator if utility is not present.
•Will transfer back to utility once utility returns (above 80% of nominal) for 15 seconds.
•Will not transfer back to utility unless utility returns. The generator will shut down if the OFF
button is pressed or a shutdown alarm is present.
•Once utility power is returned, the generator will shut down after 1 minute cool-down time.
EXERCISE
•Will not exercise if generator is already running in either AUTO or MANUAL mode.
•During exercise, the control panel will only transfer if utility fails during exercise for 6 seconds
(or 30 seconds; refer to Cold Smart Start) and will operate as normal in AUTO mode.

Owner’s Manual for 5.6 kVA PowerPact™ 13
Automatic Sequence of Operation
Utility Failure
With the generator set to AUTO, when utility fails (below
65% of nominal) a 5 second line interrupt delay time is
started. If utility is still gone when the timer expires, the
engine will crank and start. Once started, a 6 second
engine warm-up timer will be initiated (or a 30 second
warm-up timer; refer to Cold Smart Start). When the warm-
up time expires, the control panel will transfer the load to
the generator. If the utility power is restored (above 80%
nominal) at any time from the initiation of the engine start
until the generator is ready to accept load (warm-up time
has not elapsed), the control panel will complete the start
cycle and run the generator through its normal cool down
cycle, however, the load will remain on the utility source.
Cranking
The system will control the cyclic cranking as follows:
•5 cranking cycles as follows: 16 second crank,
seven (7) second rest, 16 second crank, seven (7)
second rest, followed by three (3) additional cycles
of seven (7) second cranks followed by seven (7)
second rests.
Cold Smart Start
The Cold Smart Start feature enables the generator to
monitor ambient temperature. The warm-up delay will be
adjusted based on prevailing conditions.
On a startup in AUTO mode, if the ambient temperature is
below a fixed temperature (based on model) the generator
will warm up for 30 seconds. This allows the engine to
warm before a load is applied. If the ambient temperature
is at or above the fixed temperature, the generator will
start up with the normal warm-up delay of 6 seconds.
Load Transfer
The transfer of load when the generator is running is
dependent upon the operating mode.
Shutting Generator Down While
Under Load
IMPORTANT NOTE: To turn the generator off during
utility outages to perform maintenance, or conserve fuel,
follow these steps:
To turn the generator OFF (while running in
AUTO and online):
1. Turn the main utility disconnect OFF.
2. Turn the main line circuit breaker (MLCB) on the
generator to OFF (OPEN).
3. Turn the generator OFF.
To turn the generator back ON:
1. Put the generator back into AUTO and allow to
start and warm-up for a few minutes.
2. Set the MLCB on the generator to ON.
The system will now be operating in automatic mode.
The main utility disconnect can be turned ON (CLOSED).
To shut the unit OFF, this complete process must be
repeated.

Section 4: Maintenance
Maintenance
Regular maintenance will improve performance and
extend engine/equipment life. Generac Power Systems,
Inc. recommends that all maintenance work be
performed by an Independent Authorized Service Dealer
(IASD). Regular maintenance, replacement or repair of
the emissions control devices and systems may be
performed by any repair shop or person of the owner’s
choosing. However, to obtain emissions control warranty
service free of charge, the work must be performed by an
IASD.
Performing Scheduled
Maintenance
It is important to perform maintenance as specified in the
Service Schedule for proper generator operation and to
verify that the generator complies with the applicable
emission standards for the duration of its useful life.
Service and repairs may be performed by any qualified
service person or repair shop.
Additionally, emissions-critical maintenance must be
performed as scheduled in order for the Emissions
Warranty to be valid. Emissions-critical maintenance
consists of servicing the air filter and spark plugs in
accordance with the Service Schedule. The Control
Panel will prompt for break-in or regular maintenance,
when it is required, to be performed. Break-in
maintenance consists of the oil change, valve clearance
and tune-up. Regular maintenance includes the oil, tune-
up, air cleaner, spark plug and valve clearance.
NOTE: The control panel Maintenance Due light will
flash when the initial 20 hour break-in interval has been
reached. The same light will be lit solid when following
regular maintenance intervals are required (every 1 year/
100 hours).
Clearing a Maintenance Due
Condition
After performing maintenance, the Maintenance Due light
must be cleared. To reset the Maintenance Due light, the
generator must be in OFF mode. Set the Generator to
OFF and press the OFF button to reset Maintenance
Due. If an alarm condition exists, the alarm condition
must be cleared prior to resetting the Maintenance Due
light.
