Battery Charger

NOTE: The battery charger is integrated into the control
panel module.
The battery charger ensures:
•
Output is continually
maximum battery life.
•
Charging levels are safe.
NOTE: A warning message is displayed on the LCD
screen when the battery requires service.
Transfer Switch Automatic
Operation
In AUTO, the generator starts automatically when utility
source voltage drops below the preset level. Once the
unit starts, loads are transferred to the standby power
source.
To select automatic operation:
1. Verify that the transfer switch main contacts are set
to the UTILITY position (loads connected to the
utility power source).
2. Verify that normal UTILITY power source voltage is
available to transfer switch terminal lugs N1, N2
and N3 (if three phase).
3. Move the Main Circuit Breaker switch on the
control panel up to the ON (Closed) position.
4. Press AUTO on the control pad. A green LED
illuminates to confirm that the system is in the
AUTO mode.

Automatic Sequence of Operation

Utility Failure
If the control pad is set to AUTO when the utility power
fails (falls below 65% of nominal, dealer programmable),
a ten second Start-Up Delay timer is started (user
programmable). If utility power is still absent when the
time expires, the engine cranks and starts.
Once started, a five second engine Warm-Up Delay
timer starts (user programmable). When the time has
elapsed, the load is transferred to the generator. If utility
power is restored (above 80% of nominal, dealer
programmable) between the time the engine is first
started and expiration of the warm-up time, the controller
completes the start cycle and then runs through its
normal cool-down cycle (while the load remains on the
utility source throughout the episode).

Cranking
The cyclic cranking is controlled as follows:
Fifteen (15) seconds crank, seven (7) seconds rest,
seven (7) seconds crank, seven (7) seconds rest; this
sequence is repeated for a total of six (6) crank cycles.
