Information
The following information is available about Equalize.
Parameter
Description
Where to find:
State
Indicates if Equalize is Disabled, Active, Inactive
or Pending.
SC300: Control Processes >
Equalize
Web: Control Processes >
Equalize
Next Start Time
The start time of the next scheduled Equalize.
Time shown on SC300 is UTC. Time on
PC running Web is local time. See
SC300 Internal Clock on page 19.
Remaining Time
The time to the end of the currently active
Equalize.
Voltage Offset
The adjustment to the bus voltage being applied
due to the Equalize.
Configuration
Set the following parameters.
Parameter
Description
Where to find:
First Start Time
The date and time that the first scheduled
Equalize will occur. Subsequent Equalize will
occur at every Equalize Interval after that.

DCTools/Web: Control
Processes > Equalize
Interval
The time between scheduled Equalize. The
interval period begins at the start of an Equalize.
Zero disables scheduled Equalizes.
Duration
The duration of a scheduled Equalize. Use the
value recommended by the battery
manufacturer.
Equalize Voltage
The bus voltage maintained during an Equalize
cycle. Use the value recommended by the battery
manufacturer. The bus voltage is further
adjusted by Temperature Compensation.
Activating Smart
Alarm
If this is set to a number other than zero, this
Smart Alarm number will start an Equalize cycle.
Equalize may also be used to trigger the Generator Control Output. See details on page 78.
Fast Charge
Fast Charge automatically increases the float voltage of the power system to recharge the
batteries as quickly as possible after a prolonged battery discharge.
Fast Charge does
NOT
function during a Battery Test, Equalize or if the battery current sensor
fails.
If Fast Charge is used then Battery Current Limit (BCL) should also be used. See Battery Current
Limit on page 28 for details.
If Fast Charge cannot start at the scheduled time (for example when there is no ac supply) then its
state will be Pending and it will start as soon as conditions allow. Use Stop Fast Charge to cancel a
Pending Fast Charge.
