Cold Smart Start
The Cold Smart Start feature is enabled at the factory, but
can be disabled in the EDIT menu. The generator will
monitor ambient temperature when Cold Smart Start is
enabled. The warm-up delay will be adjusted based on
prevailing conditions.
If the ambient temperature is below a fixed temperature
(based on model) upon startup in AUTO mode, the
generator will warm up for 30 seconds. This allows the
engine to warm before a load is applied. The generator
will startup with the normal warm-up delay of 5 seconds if
the ambient temperature is at or above the fixed
temperature.
A check for proper output voltage build up will be
performed when the generator engine is started.
If some condition impedes normal voltage creation, such
as frost crystals or dust/dirt preventing a good electrical
connection, the start sequence will be interrupted so that
a cleaning cycle of the internal electrical connections can
be attempted.
The cleaning cycle is an extended warming up period
which lasts for several minutes while the normal genera-
tor voltage output is determined to be low. During this
cycle, the generator controller will display “Warming Up”
on the display screen.
The generator controller display will show “Under
Voltage” if the cleaning cycle fails to clear the obstruction.
After several minutes, the alarm message can be
cleared, and the generator restarted.
If the problem persists, make no further attempts to start.
Contact an IASD.
Load Transfer
The transfer of load when the generator is running is
dependent upon the operating mode.
Shutting Generator Down While
Under Load Or During An
Extended Outage
Proceed as follows to turn the generator off during utility
outages to perform maintenance or conserve fuel:
To turn the generator OFF (while running in
AUTO and online):
1. Turn the main utility disconnect off.
2. Turn the MLCB (generator disconnect) on the
generator to OFF (OPEN).
3. Allow generator to run approximately 1 minute for
proper cooling.
4. Press the OFF button on the controller.
To turn the generator back ON:
1. Put the generator into AUTO and allow to start and
warm-up for a few minutes.
2. Set the MLCB (generator disconnect) on the
generator to ON (CLOSED).
The system is now in automatic mode. The main utility
disconnect can be turned ON (CLOSED). To shut the unit
off, this complete process must be repeated.
