Battery Charger
NOTE: The battery charger is integrated into the control
module in all models.
The battery charger operates as a “Smart Charger” that
ensures:
•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 that the generator is in the OFF mode.
2. Set the main circuit breaker (Generator
Disconnect) to OFF or OPEN.
3. Turn off the utility power supply to the transfer
switch using the means provided (such as a utility
main line circuit breaker).
4. Use the manual transfer handle (A in Figure 3-7)
inside the transfer switch to move the main
contacts to the STANDBY position (loads
connected to the standby power source).
5. To crank and start the engine, press the control
panel MANUAL button.
6. Allow the engine to stabilize and warm up for a few
minutes.
7. Set the main circuit breaker (Generator
Disconnect) to ON or CLOSED. The standby
power source now powers the loads.

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).
•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 a 5 second engine warm-up timer (or 30 seconds; refer to Cold Smart Start).
–Will not transfer if utility subsequently returns.
–Will transfer to generator if utility is not present.
•Will transfer back to utility once utility returns (above 80% of nominal) for 15 seconds.
•Will not transfer back 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 five seconds
(or 30 seconds; refer to Cold Smart Start), and will switch to AUTO.

Operation
Owner’s Manual for 50 Hz Air-Cooled Generators 15
Transfer Back to Utility Power Source
When utility power has been restored, transfer back to
utility source and shut down the generator. To manually
transfer back to utility power and shut down the
generator:
1. Set the Main Circuit Breaker (Generator
Disconnect) to OFF or OPEN.
2. Allow the engine to run for two minutes at no-load
to stabilize the internal temperatures.
3. Press the control panel OFF button. The engine
should shut down.
4. Ensure that utility power supply to the transfer
switch is turned off.
5. Use the manual transfer handle (A in Figure 3-7)
inside the transfer switch to move the main
contacts back to the UTILITY position (loads
connected to the utility power source).
6. Turn on the utility power supply to the transfer
switch using the means provided.
7. Press the control panel AUTO button.
Automatic Transfer Operation
To select automatic operation:
1. Make sure the transfer switch main contacts are
set to the UTILITY position (loads connected to the
utility power source).
2. Be sure 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 main circuit breaker (Generator
Disconnect) to the ON (Closed) position.
With these steps complete, the generator will start
automatically when utility source voltage drops below a
preset level. After the unit starts, loads are transferred to
the standby power source.
Automatic Sequence of
Operation
Utility Failure
With the generator set to AUTO, when utility fails (below
65% of nominal) a five second (dealer programmable)
line interrupt delay time is started. If utility is still gone
when the timer expires, the engine will crank and start.
Once started, a five 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 controller 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 (five second warm-up time has not elapsed),
the controller 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:
•Five 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 can be enabled in the EDIT
menu. With Cold Smart Start enabled, the generator will
monitor ambient temperature and 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 startup with the normal warm-up delay of 5
seconds.
When the generator engine is started, a check for proper
output voltage build up will be performed.
If some condition impedes normal voltage creation, such
as frost crystals or dust/dirt prevent 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 the
“Warming Up” on its display screen.
If the cleaning cycle fails to clear the obstruction, the
generator controller display will show the “Under Voltage”
message.
After several minutes, the alarm message can be
cleared, and a restart of the generator attempted.
If the problem persists, make no further attempts to start.
Contact an Independent Authorized Service Dealer.
Load Transfer
The transfer of load when the generator is running is
dependent upon the operating mode.
