voltage is held at the float voltage set point.
Equalize
The Equalization function can be manually initiated or can be set up to Auto Equalize. The intent of an
Equalization charge is to bring all battery cells to an equal
voltage by a controller deliberate overcharge.
The goal is to return each battery cell to its optimum condition through a series of voltage controlled
chemical reactions inside the batteries.
Resting
“Resting” will show on the display when the Classic is not charging the batteries, this is typically due to
low light. If the Classic is resting and should not be, make sure Aux2 is
not
set to a logic input that is
forcing it into resting.
Mode is OFF
The Classic has a software “ON” and “OFF” feature. This software “Switch” basically turns the relay off,
effectively disconnecting the input source so the Classic will not charge the battery. If you see “
Mode is
Off
” in the bottom right corner of the display then the Mode may have been turned off. To turn the mode
back “ON” push the Main Menu button several times until “Charge” is highlighted. Scroll to the right
until “Mode” is highlighted and press “Enter”. On this screen “OFF” should be highlighted use the up or
down arrow to change it to “ON” and press “Enter”. Press the Status button once to return to the main
status screen.
Adjusting Absorb, Equalize and Float Voltages
The table below describes the default preset voltages for the different nominal battery voltages. This
means that if you set the Classic from the QUICK START to a different battery voltage the Classic will
take the default voltage set points. Note. If you manually adjust the absorb float or equalize voltage set
points, and then nominal battery voltage is changed to a different nominal voltage, (e.g. from 24v to 12v
or to 48v etc.), manual adjustments may be required.
