Operation
14 Owner’s Manual for 50 Hz Air-Cooled Generators
Setting the Exercise Timer
This generator is equipped with a configurable exercise
timer. There are two settings for the exercise timer:
Day/Time: The generator will start and exercise for the
period defined, on the day of the week and at the time of day
specified. During this exercise period, the unit runs for
approximately 12 minutes at 3000 rpm and then shuts down.
NOTE: The exercise timer does not automatically adjust for
Daylight Savings Time.
Exercise frequency: Exercise frequency can be set to
Weekly, Biweekly, or Monthly. If Monthly is selected, the day
of the month must be selected from 1-28. The generator will
exercise on that day each month. Transfer of loads to the
generator output does not occur during the exercise cycle
unless utility power is lost.
NOTE: If the installer tests the generator prior to
installation, press the ENTER button to skip setting up the
exercise timer.
NOTE: The exercise feature will operate only when the
generator is in AUTO mode, and will not work unless this
procedure is performed. The 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.
The exercise timer must be reset if the 7.5 amp fuse is
removed.
Battery Charger
NOTE: The battery charger is integrated into the control
module in all models.
The battery charger operates as a smart charger that
verifies:
•output is continually optimized to promote
maximum battery life.
•charging levels are safe.
NOTE: A warning is displayed on the LCD when the
battery needs service.
Manual Transfer Operation
Prior to automatic operation, manually exercise the
transfer switch to verify that there is no interference with
proper operation of the mechanism. Manual operation of
the transfer switch is required if electronic operation
should fail.
Transfer to Generator Power Source
1. Verify generator is OFF.
2. Set the main line circuit breaker (MLCB) (generator
disconnect) to OFF (OPEN).
3. Turn off the utility power supply to the transfer
switch using the means provided (such as a main
line utility breaker).
4. Use the manual transfer handle (A in Figure 3-8)
inside the transfer switch to move the main
contacts to STANDBY (loads connected to the
standby power source).
5. Press the control panel MANUAL button to crank
and start the engine.
6. Allow the engine to stabilize and warm up for a few
minutes.
7. Set the MLCB (generator disconnect) to ON
(CLOSED). The standby power source now
powers the loads.

(000132)
DANGER
Electrocution. Do not manually transfer under load.
Disconnect transfer switch from all power sources
prior to manual transfer. Failure to do so will result
in death or serious injury, and equipment damage.

Operation
Owner’s Manual for 50 Hz Air-Cooled Generators 15
Transfer to Utility Power Source
When utility power has been restored, transfer to utility
source and shut down the generator. Proceed as follows
to manually transfer to utility power and shut down the
generator:
1. Set the MLCB (generator disconnect) to OFF
(OPEN).
2. Run engine for two minutes at no-load to stabilize
the internal temperature.
3. Press the control panel OFF button. The engine
will shut down.
4. Verify that utility power supply to the transfer switch
is turned off.
5. Move the main contacts to the UTILITY position
(loads connected to the utility power source) using
the manual transfer handle (A in Figure 3-8) inside
the transfer switch.
6. Turn on the utility power supply to the transfer
switch using the means provided.
7. Press the control panel AUTO button.
8. Return the MLCB (generator disconnect) to ON
(CLOSED).
Automatic Transfer Operation
Proceed as follows to select automatic operation:
1. Verify that the transfer switch main contacts are set
to UTILITY (loads connected to the utility power
source).
2. Verify that normal utility power source voltage is
available to transfer switch terminal lugs N1 and
N2.
3. Press the AUTO button on the control panel
interface.
4. Set the MLCB (generator disconnect) to ON
(CLOSED).
The generator will start automatically when utility source
voltage drops below a preset level. Loads are transferred
to the standby power source after the unit starts.
MANUAL
•Will not transfer to generator if utility is present.
•Will transfer to generator if utility fails (below 65% of nominal for five consecutive seconds)
after warm-up.
•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 for five consecutive seconds (factory default).
•Will start an engine warm-up timer (duration varies when Cold Smart Start is enabled).
–Will not transfer if utility subsequently returns.
–Will transfer to generator if utility is not present.
•Will transfer to utility once utility returns (above 80% of nominal) for 15 seconds.
•Will not transfer 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 one minute cool-down time.
EXERCISE
•Will not exercise if generator is already running in either AUTO or MANUAL mode.
•During exercise, the controller will only transfer if utility fails during exercise for 10 seconds
(varies based on Cold Smart Start) and will switch to AUTO.

Operation
16 Owner’s Manual for 50 Hz Air-Cooled Generators
Automatic Sequence of Operation
Utility Failure
If the generator is set to AUTO, when utility fails (below
65% of nominal) a 5 second (dealer programmable) line
interrupt delay time is started. The engine cranks and
starts if the utility is still gone when the timer expires. An
engine warm-up timer will be initiated once started. Timer
duration varies depending on whether or not Cold Smart
Start is enabled. The controller will transfer the load to
the generator when the warm-up time expires. 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
controller completes the start cycle and runs the
generator through its normal cool down cycle. However,
the load will remain on the utility source.
Cranking
The system will go through five cyclic cranking cycles as
follows: 16 seconds cranking, 7 seconds resting, 16
seconds cranking, 7 seconds resting, followed by three
additional cycles of 7 seconds cranking followed by 7
seconds resting.
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.
