Battery Type (Custom)
– This selection allows you to individually adjust the
fl
oat,
absorb, and equalization charge voltage settings and to set an equalization time for your
batteries. This allows the multi-stage charging method (see Figure 12-3) to be customized
speci
fi
cally for your batteries. Use the following Custom battery settings to determine the
battery’s absorption,
fl
oat, and equalization voltages, and the maximum amount of time
spent equalizing.
Custom Chg Settings
Set Absorb Volts
– Sets the level at which the charging voltage is held constant during
the Absorption charge.
Default:
12.0V (12v)
,
24.0V (24v), 48.0V (48v)
Range:
12.0-16.0V (12v)
,
24.0-32.0V (24v), 48.0-64.0V (48v)
Set Float Volts
– Sets the level at which the charging voltage is held constant during
the Float charge.
Default:
13.2V (12v)
,
26.4V (24v), 52.8V (48v)
Range:
12.0-16.0V (12v)
,
24.0-32.0V (24v), 48.0-64.0V (48v)
Set EQ Volts
– Sets the level at which the charging voltage is held constant during the
Equalization charge.
Note:
EQ Volts
setting cannot be set lower than the
Absorb Volts
setting, or more than 2 volts
(12v systems), 4 volts (24v systems), or 8 volts (48v systems) above the
Absorb Volts
setting.
Default:
14.0V (12v),
28.0V (24v), 56.0V (48v)
Range:
12.0-16.0V (12v)
,
24.0-32.0V, 48.0-64.0V (48v)
Set EQ Done Time
– Sets the time (duration) the battery charges at the
EQ Volts
setting.
Default:
4.0 Hrs
Range:
0.1-25.5 Hrs
Info:
The internal timer for the
EQ Done Time
setting counts when the battery voltage
is equal to the
EQ Volts
setting, and clears when the controller status goes to
Float
Charging
. It clears automatically when the EQ charging
fi
nishes, or can be manually
cleared by selecting
Float Start
(under the
CTRL: 05A PT CHG Ctrl
menu).

Volts
– This setting holds the battery voltage at the
CV Charge Volts
setting. This is for a system that requires a constant charge voltage to be present at all
times (see Figure 12-2).
