Set Battery Type ( CC/CV) –
The
CC/CV
selection provides a 2-stage (Constant Current/
Constant Voltage) charging cycle with an adjustable charge voltage and output current.
Note
:
CC/CV settings only display if CC/CV has been selected from the 03 Battery Type menu.
Info:
If
CV/CC
has been selected from the
03C Battery Type
menu, the following
menus are no longer accessible and display “
CC/CV Controlled
” when selected:
01H
Max System Charge Amps,
03D Absorb Done
,
03E Max Charge
,
03F Final Charge, 07B
Absorb Done
. This prevents charging con
fl
icts occurring while in the CC/CV pro
fi
le.
CAUTION:
Whenever the CC/CV battery type is selected, some settings—within menus
that are no longer accessible—are internally linked to the CC/CV settings and can be
automatically changed. Because settings can be automatically changed once CC/CV has
been selected, if a different battery type is selected, then all charge settings must be
reviewed to ensure they are correct for the new battery type selection.
CC/CV Chg Settings
□
Max Chg Rate
–
A safety feature that ensures abnormal conditions do not cause the
charger to hold batteries at a high voltage for a prolonged period of time. This menu
sets a maximum time the charger is allowed to operate in either the Bulk, Absorption, or
Equalization charge modes. If the charger reaches the maximum charge time setting, it
transitions to the
fi
nal charge stage as set in the SETUP button’s
03F Final Charge Stage
.
Default:
Rate = 100%
Range:
0-100%
□
CV Chg Volts
– Sets the voltage level at which the charger holds the batteries during
the Constant Voltage cycle.
Default:
CV Chg Volts = 13.8 VDC (12v), 27.6 VDC (24v), 55.2 VDC (48v)
Range:
OFF, 12.0-16.0 VDC (12v), 24.0-32.0 VDC (24v), 48.0-64.0 VDC (48v)
CV Chg Done Time, CV Chg Done Amps, or Hold CV Chg Volts selections:
These selections
determine when the second stage of charging (Constant Voltage) is
fi
nished. If using the
CV
Charge Done Time
or
CV Charge Done Amps
selections, once the constant voltage charge cycle
is
fi
nished, it transitions to a Silent charge stage. During the Silent charge mode, charging is
automatically stopped, but battery voltage is still monitored. The charger remains “Silent” until
the battery voltage drops to the
Set DC Volts to Recharge
setting, at which time the charger
starts another Constant Current/Constant Voltage charge cycle (Figure 3-12).
The
Hold CV Chg Volts
selection holds the battery in the constant voltage charge cycle voltage
at the
CV Chg Volts
setting inde
fi
nitely (see Figure 3-13).
□
CV Chg Done Time
(default) – The
CV Charge Done Time
selection is used when a
speci
fi
c time is selected to be the best solution for determining when the batteries are fully
charged and the Constant Voltage stage needs to end.
*
Set CV Charge Done Time
– This setting determines how long the charger holds
the battery voltage at the
CV Chg Volts
setting—per a set time period. When using time,
the battery bank size typically determines the length of the
CV Charge Done Time
setting.
The larger the battery bank, the longer the time needed to ensure a full battery charge.
The charger transitions to Silent charge mode after the battery voltage has been at the
CV
Chg Volts
setting for the selected time. Refer to Table 3-2 to assist you in selecting the
CV
Charge Done Time
setting based on the AHr capacity of your battery bank.
Note:
After choosing the Set CV Charge Done Time, the Set Max CC/CV Charge Time and
Set DC Volts to Recharge settings must be determined.
Default:
Time = 2.0 Hrs
Range:
0.1-25.5 Hrs
□
CV Chg Done Amps
– The
CV Charge Done Amps
setting is used when the DC amperage
supplied to the batteries (i.e., done amps) determines when the batteries are fully charged
and the Constant Voltage stage needs to end.
