Operation
Managing the Battery Bank
25
The battery bank is typically charged in three stages as described in section
entitled Stages of Charging in the User Manual. Once the battery bank is
fully charged, the WhisperGen
TM
stops automatically and returns to the
standby mode. Regardless of heat management settings, the WhisperGen
TM
will stop once the battery bank is fully charged if the WhisperGen
TM
had
been started by the auto-charge function.
While the WhisperGen
TM
is auto-charging the battery bank, you
can stop it at any time by pressing STOP on the control panel. However, the
WhisperGen
TM
will immediately start again if the battery bank charge level is
still below the preset level. To prevent the WhisperGen
TM
from restarting,
turn the Auto-charge option OFF
If the WhisperGen
TM
was started by the auto-charge function, the Max Run
Hours setting does not affect the operating time of the WhisperGen
TM
.
Regardless of the Max Run Hours setting, the WhisperGen
TM
will fully
charge the battery bank before stopping. For a summary on operating
options, see the Quick Reference in the User Manual.
Bulk-charging the Battery Bank
While the WhisperGen
TM
is running, you can start a new cycle of battery
bank charging, that is, return to bulk-charging the battery bank, see section
Stages of Charging. This can be done regardless of auto-charging and heat
management settings.
To bulk-charge the battery bank while the WhisperGen
TM
is running:
Hold down START on the control panel until you hear a beep. The control
panel displays "Bulk charge". As an anti-tamper feature, short presses of
the
START key are ignored.
Bulk charge
A new charging cycle, beginning with bulk-charging, will be started. See
section Stages of Charging.
