Ascend Single Phase Charger Operation Manual
6.6.2. Float/Equalize Modes
Float mode is used to maintain stationary batteries in a fully charged state. When the charger is in Float
mode the output voltage is maintained at the float voltage setting.
Equalize mode is used to help remove built-up sulphate and balance the voltage of each cell. An Equalize
Timer is used to limit the time of the Equalize charge on the batteries to prevent damage. Before
adjusting equalize settings, consult your battery datasheets.
The Equalize Time is 24 hours default from the factory. To change the time, go to the Setup ->
Adjustments -> Equalize Time Menu. The range is 1 minute to 99 Hours (5,940 minutes).
To reduce the risks of applying an Equalize charge to batteries that do not require a equalize charge, the
Equalize mode function can be disabled. To disable go to the Setup -> Adjustments -> Equalize Enable
Menu.
An Automatic Equalize function is available to automatically place the Charger in Equalize mode after an
AC power failure greater than 5 minutes. See 7.4.8. Charger Auto−Equalize.
The Battery Control Button on the Mimic screen displays the status of the Charger output to the battery.
Charge is in Float Mode.
Charge is in Equalize mode.
Battery is discharging. All modules failed or Battery discharging alarm when Battery
Voltage & Current option is provided, reference 7.7.2. Battery Voltage & Current
Monitoring.
There is no communication with the Charger modules when the Battery current metering
is not included.
