Float Voltage
Float voltage is the standard output voltage of the system. This may be modified by the various
control processes.
Configuration
Set the following parameter.
Parameter Description Where to find:
Float Voltage Set to the voltage required to maintain optimum
battery charge (at the nominal ambient
temperature*) as specified by the battery
manufacturer. The bus voltage may be adjusted
above or below this value by the System Control
Processes.
*This is the same as the Reference
Temperature used by Temperature
Compensation. See details on page 35.

Alternative Float
Voltage
When Alternative Float Smart Alarm is active, the
float voltage is changed to this value.
Alternative Float
Smart Alarm
When Alternative Float Smart Alarm is active, the
float voltage is changed to Alternative Float
Voltage.
The system voltage is limited by maximum and minimum values. The values are viewable in
DCTools/Web at Control Processes > Voltage Control. These values are not configurable by Web
or DCTools. If these must be changed, contact your Eaton representative for access to ICE
software.
Alternative Float Voltage
Alternative Float Voltage is an alternative operating voltage that can be used in particular
circumstances, particularly when a special battery charging regime is used.
When Alternative Float Smart Alarm is active, Alternative Float Voltage will be used instead of
Float Voltage.
Configuration
Set the following parameters.
