CHARGE PARAMETER SETTINGS
The SC30 contains various charge parameter settings all of which are preconfigured at the factory to the default settings shown below. Most
installations require no changes to these settings which are typically suitable for most flooded, GEL and AGM lead-acid chemistry batteries.
¾ WARNING: If charge parameter settings are changed, confirm that the new settings comply with the battery manufacturers
recommendations. DO NOT enable equalization for sealed lead-acid batteries such as GEL and AGM.
As Shipped Factory Default Settings
• Charge mode .............................................. 3-stage • Equalize enable ........................................................ Off (disabled)
• Absorption voltage ..................................... 14.4V • Equalize time ............................................................ 2.0 hours
• Absorption time .......................................... 2.0 hours • Equalize voltage ....................................................... 15.2V
• Float voltage ................................................ 13.2V • Auto equalize days ................................................... 30 days
• Maximum setpoint voltage limit .................. 15.5V • Temperature compensation factor ........................... −30mV/°C
Changing Charge Parameter Settings
SC30 charge parameter settings may be viewed or changed at any time using a combination of the Setup and Display Select push-buttons. There are
two modes of setup operation, Viewing a setting and Changing a setting. Basic operation is to go from Normal Operation to Viewing Mode, Viewing Mode to
Changing Mode, and then from Changing mode back to Viewing mode, and Viewing Mode back to Normal Operation. All settings are stored in Flash memory
and are retained if power is lost.

Parameter Changing Mode
Viewing a setting
To enter the Viewing Mode press Setup 5 seconds and release when AbS appears in the display. The first
parameter to be shown is the Absorption Charge Voltage setting. The display will alternate between AbS and 14.4
to show the present Absorption Charge Voltage setting is 14.4V.
A brief press of Setup within 5 seconds will move to the next setting shown in Table 2, Absorption Charge Time
where the display will now alternate between Abt and 2.0 to show the present Absorption Charge Time setting is
2.0 hours. Remaining settings may be viewed by repeatedly pressing Setup to move to the desired setting. To exit
Viewing Mode and return to normal operation, do not press Setup for 5 seconds.
Changing a setting
To enter the Changing Mode, first enter the Viewing Mode for the setting to be changed. While in Viewing Mode for
that setting, press Setup 5 seconds to enter the Changing Mode for that setting. The present setting value will begin
blink rapidly indicating that you have entered the parameter changing mode for that setting. Use Display Select to
scroll through the available values until the desired value is reached. With the desired new value blinking in the
display press Setup 5 seconds to save the new setting. Once the new setting is saved the display will revert back
to the Viewing Mode showing the new saved value for that setting.
If neither Setup or Display Select is pressed within 5 seconds while in the Changing Mode, the change request is
abandoned and the display reverts back to Viewing Mode without changing the setting.
