With the
Auto-charge
option turned
ON
, the WhisperGen will automatically start whenever the
battery bank charge level falls below a preset level. This “threshold” level is set during the
installation of the WhisperGen according to the needs of your particular application. If you wish to
change it, contact your authorised WhisperGen agent.
The battery bank is typically charged in three stages as described in section entitled Stages of
Charging. Once the battery bank is fully charged, the WhisperGen stops automatically and
returns to the standby mode. Regardless of heat management settings, the WhisperGen will stop
once the battery bank is fully charged if the WhisperGen had been started by the auto-charge
function.
If the WhisperGen was started by the auto-charge function, the
Max Run Hours
setting does not
affect the operating time of the WhisperGen. Regardless of the
Max Run Hours
setting, the
WhisperGen will fully charge the battery bank before stopping.
For a summary on operating options, see section entitled Quick Reference - Operating Options.
Bulk-charging the Battery Bank
While the WhisperGen 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 is running:
Hold down
START
on the control panel until a beep is heard. The control panel will display “Bulk
charge”. As an anti-tamper feature, short presses of the
START
key are ignored.
A new charging cycle, beginning with bulk-charging, as described in section Stages of Charging
will be started.
While the WhisperGen is auto-charging the battery bank, you can stop
it at any time by pressing STOP on the control panel. The WhisperGen
will however immediately start again if the battery bank charge level is
still below the preset level. To prevent the WhisperGen from restarting,
turn the Auto-charge option OFF.
