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.
