INSTALLATION & OPERATION
Equalization Procedure
Standard Equalization Programs
Both automatic and manual equalizations can be performed using the standard
charging programs.
Manual Equalization
The SCC-30AB is shipped with the DIP Switch set for manual equalization only.
This is to avoid an unexpected or unwanted automatic equalization. In the Manual
Mode, the pushbutton is used to both start and stop a manual equalization. Hold
the pushbutton down for 5 seconds to start and 3 seconds to stop an equalization
(depending on whether an equalization is in progress or not).
There are no limits to how many times the pushbutton can be used to start and stop
equalizations. Equalizations will be terminated automatically as per the charging
program selected if the pushbutton is not used to manually stop the equalization.
Automatic Equalization
If the equalization DIP Switch 5 is moved to the ON position, the equalizations will
begin automatically as per the charging program selected. Other than starting, the
automatic and manual equalizations are the same and follow the standard charging
program selected. The push button can be used to start and stop equalizations in both
the manual and automatic mode.
Typical Equalization
The automatic equalizations will occur at the selected charging program from DIP
Switch 2~4. When equalization begins (Auto or Manual), the battery charging voltage
increases up to the Equalization Voltage Veq. The battery will remain at Veq for the
time specied in the selected charging program.
The equalization process will continue until the voltage has been held above the
bulk setting for a cumulative period of one, two or three hours. A second manual
equalization cycle can be started with the pushbutton, if needed.
If the equalization cannot be completed in one day, it will continue the next day
or days until nished. After equalization is completed, charging will return to PWM
Absorption.
