Battery Charger

NOTE: The battery charger is integrated into the control
module in all models.
The battery charger operates as a smart charger that

Automatic Sequence of
Operation

Cranking

The system will control the cyclic cranking 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 monitors the ambient
temperature and adjusts the warm-up delay upon start up
in AUTO mode based on prevailing conditions.
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
generator 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.

Will not transfer to generator if MLCB (generator disconnect) is OFF (OPEN).
Will transfer to generator if MLCB (generator disconnect) is ON (CLOSED).
Will start and run when remote two-wire start is ON (CLOSED).
The generator will shut down if the OFF button is pressed or a shutdown alarm is present.
Once remote two-wire start is OFF (OPEN), the generator will shut down immediately (a
selectable cool down is provided; default is no cool down)

NOTE: A warning is displayed on the LCD when the
battery needs service.
Shutting Generator Down While
Under Load Or During An
Extended Run
Proceed as follows to turn the generator off during an
extended run to perform maintenance or conserve fuel:
To turn the generator OFF (while running in
AUTO and online):
1. Turn the MLCB (generator disconnect) on the gen-
erator to OFF (OPEN).
2. Allow generator to run approximately 1 minute for
proper cooling.
3. 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 connected
loads can be engaged.
