All settings are for 12 Volt nominal systems. Multiply the charge voltage settings by 2 for 24 Volt
systems or by 4 for 48 Volt systems. A description of each setting is provided below. See sec-
tion 4.3 for full details on battery charging and a description of each of the settings in the battery
charging table.
Battery Type-Themostcommonbatterytypeassociatedwiththespeciedchargingsettings.
Absorption Stage - This stage limits input current so that theAbsorption voltage is maintained.
As the battery becomes more charged, the charging current continues to taper down until the
battery is fully charged.
Float Stage - When the battery is fully charged, the charging voltage will be reduced to the Float
voltage setting.
Equalize Stage - During an equalization cycle, the charging voltage will be held constant at the
speciedvoltagesetting.
Equalize Interval - The number of days between equalization charges when the controller is con-
guredforautomaticequalizations(settingsswitch7).
Switch 7: Battery Equalization
Choose between manual and automatic battery equalization charging. In the manual equaliza-
tion setting, an equalization will only occur when manually started with the push-button or when
requested from the equalize menu on the TriStar meter. Automatic equalization will occur accord-
ingtothebatteryprogramspeciedbysettingsswitches4,5,&6inthepreviousstep.

20 Installation
In both settings (auto and manual), the push-button can be used to start and stop battery equal-
ization. If the selected battery charging setting does not have an equalization stage an equaliza-
tion will never occur, even if requested manually.

activé par les connexions RS-232 et EIA-485. Le contacteur de sécurité Ethernet n’active/
désactive que la conguration à distance par TCP/IP.
PRUDENCE : Risque de tentative d’altération
Le contacteur des paramètres de sécurité Ethernet ne bloque pas les commandes d’écriture sur
les dispositifs reliés par EIA-485.
