Setup
*
Hold CV Chg VDC
– This setting holds the battery voltage at the
CV Charge Volts
set-
ting. This is for a system that requires a constant charge voltage to be present at all times
(see Figure 3-11).
◊
Set Battery Type (Custom)
–
This selection allows you to individually adjust the Float,
Absorb, and Equalization charge voltage settings and to set an equalization time for your bat-
teries. The following Custom battery settings display only if
Custom
has been selected from
the
03 Battery Type
menu. Use these settings to determine the battery’s absorption,
fl
oat,
and equalization voltages, and the maximum amount of time spent equalizing.
CAUTION:
To avoid damage during battery charging or equalization, consult the battery
manufacturer to ensure the best charge settings are used for your type of batteries.
Absorb Volts
– Sets the level at which the charging voltage is held constant during an
Absorption cycle.
Default:
14.4V (12v)
,
28.8V (24v), 57.6V (48v)
Range:
12.0-16.0V (12v)
,
24.0-32.0V (24v), 48.0-64.0V (48v)
Float Volts
– Sets the level at which the charging voltage is held constant during a Float
cycle.
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)
EQ Volts
– Sets the level at which the charging voltage is held constant during an Equal-
ization cycle.
Note:
The
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:
15.6V (12v),
31.2V (24v), 62.4V (48v)
Range:
12.0-16.0V (12v)
,
24.0-32.0V, 48.0-64.0V (48v)
EQ Done Time
– Sets the time (duration) the battery will charge at the
EQ Volts
setting
.
Default:
4.0 Hrs
Range:
0.1-25.5 Hrs
Info:
The timer for the
EQ Done Time
setting: a) Counts when EQ is enabled and the
voltage is close to the
EQ Volts
setting (
≤
0.1v/12-volt systems,
≤
0.2v/24-volt systems,
or
≤
0.4v/48-volt systems); b) Pauses when in Charger Standby; c) Clears when EQ is
fi
nished, the battery goes to Bulk/Absorb or Float, or EQ is stopped.
