Setting the Exercise Timer
This generator is equipped with a configurable exercise
timer. Configuration can be performed directly at the con-
trol panel. There are two settings for the exercise timer:
Day/Time:
Generator will start and exercise for period
defined, on day of week and at time of day specified.
During this exercise period, unit runs for approximately
five minutes and then shuts down.
Exercise frequency:
Exercise frequency can be set to
Weekly, Biweekly, or Monthly. If Monthly is selected, day
of month must be selected from 1–28. Generator will
exercise on that day each month. Transfer of loads to
generator output does not occur during exercise cycle
unless PWRcell inverter initiates a startup.
NOTE:
The exercise feature will operate only when gen-
erator is in AUTO, and will not work unless this procedure
is performed. Current date/time will need to be reset
every time the 12 volt battery is disconnected and then
reconnected, and/or when the fuse is removed.

options for all home standby generators.
Battery Charger
IMPORTANT NOTE: Contact an IASD if controller
screen displays “LOW REBUS VOLTAGE WARNING.”
NOTE:
Battery charger is integrated into the converter
module.
The battery charger operates as a smart charger which
verifies:
•
output is continually optimized to promote maxi-
mum battery life.
•
charging levels are safe.
NOTE:
A warning is displayed on LCD when battery
needs service.
NOTE:
Do not use external battery chargers.
Automatic Sequence of Operation
Cranking
The system will control the cyclic cranking as follows:
•
9 kW Unit:
five cranking cycles as follows: 10 sec-
onds cranking, seven seconds resting, followed by
four additional cycles of 10 seconds cranking fol-
lowed by seven seconds resting.
NOTE:
An alarm will be triggered if generator does not
start after these five attempts.
Cleaning Cycle
If some condition impedes normal voltage creation, such
as frost crystals or dust/dirt preventing a good electrical
connection, start sequence will be interrupted so a clean-
ing cycle of the internal electrical connections can be
attempted.
Cleaning cycle is an extended warm up period which
lasts for several minutes while normal generator voltage
output is determined to be low. During this cycle, genera-
tor controller will display “Warming Up” on the display
screen.
The generator controller display will show “Under Volt-
age” if cleaning cycle fails to clear the obstruction. After
several minutes, alarm message can be cleared, and the
generator restarted.
If the problem persists, make no further attempts to start.
Contact an IASD.
Shutting Generator Down While
Under Load or During a Utility Outage
IMPORTANT NOTE: To avoid equipment damage,
follow these steps, in order, during utility outages.
Shutdowns may be required during utility outages to
perform routine maintenance or to conserve fuel.
To turn generator OFF:
1.
Disable generator in PWRcell Inverter device page
submenu. Generator will enter 60 second cool-
down. Allow cool-down to complete and generator
to shut off.
2.
Set generator MLCB (generator disconnect) to
OFF (OPEN).
3.
Set PWRcell Inverter DC disconnect for PWRgen-
erator to OFF (OPEN).
4.
Press OFF button on generator controller.
5.
Remove 7.5A fuse from controller.

DANGER
Automatic start-up. Disconnect power and render
unit inoperable before working on unit. Failure to do
so will result in death or serious injury.
