Operation
5. Use the manual transfer handle (A in
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 5 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
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 (5 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

Figure 3-8)
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
five 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, dust, or 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 the
"Warming Up" on the 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:
