3.4.4 Equalize
Voltage
The “Equal. Voltage” setting allows the user to adjust the equalize voltage supplied by the charger. Equalize
voltage is adjustable by both the total output voltage and volts per cell. To change the equalize voltage select
“Equal. Voltage” in the “Output Settings” menu. To switch between volts per cell and total output voltage press
the LEFT and RIGHT buttons.
The approximate adjustable range is as follows:
2.15 – 2.50 V/C (LA) (VRLA) and 1.40 – 1.70 V/C (NC)
3.4.5 Equalize Mode Settings
The “Equalize Mode” menu provides access to set the Equalize Timer Hours, Equalize
Timer Mode, and Remote Equalize Settings. The equalize timer modes are discussed
in detail in
Section 2.3.1 Equalize Timer Modes
.
Equalize Timer Hours
The Equalize Timer Hours setting changes the amount of time that the charger remains in the equalize charging
cycle once activated. When an equalize cycle is started the charger will remain in equalize mode until the time
selected by this setting has passed. The equalize timer can be set between 1-144 hours, by default the equalize
timer is set for 8 hours.
Equalize Timer Mode
The Equalize Timer Mode determines when the charger will go into an equalize charging cycle. The timer modes
are “Auto EQ OFF”, “7 Day Auto EQ”, “14 Day Auto EQ”, “30 Day Auto EQ”, and “Auto EQ on LV”. The default
setting for the equalize timer mode is Auto EQ OFF. The Equalize Timer Modes are discussed in further detail in
Section 2.3.1 Equalize Timer Modes
.
Remote Equalize
Remote Equalize enables two chargers connected in parallel to enter equalize simultaneously. In order for
Remote Equalize to function, there must be additional wires connected linking chargers together. To properly
wire chargers for Load Sharing/Remote Equalize see
Section 1.7 Enabling Load Sharing
. To enable Remote
Equalize select “Enbl Remote Eq” in the “Equalize Mode” Menu and select YES.
3.4.6 Current
Limit
The Current Limit adjustment allows the customer to adjust the maximum current
output of the charger. The Current Limit is adjustable between 50% and 115% of
the nameplate rating, and the default setting is 110%. The current limit setting is
adjustable in 0.1A increments.
Ex: A 30A A77 charger has a current limit adjustment of 15-34.5A.
