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.
