3.0 Setup
Info:
A ME-BMK/ME-BMK-NS is required in order for the
Absorb
Done SOC
setting to be used. If the
Absorb Done SOC
setting
is selected and there is no ME-BMK/ME-BMK-NS installed in
the system, then the
Absorb Done SOC
setting will be based
on the value selected in the SETUP menu’s
05B AmpHour Size
menu item.
Info:
If the
Absorb Done SOC
setting is used when charging
from a generator source, then it is recommended that a setting
of less than 100% be used (usually around 90% is acceptable).
This lower setting is used because running the generator past
the 90% setting is sometimes considered an inef
fi
cient use of
fuel. If a setting lower than 100% is used, then at least once a
week the batteries should be charged to 100%, to make sure
damage is not done to the batteries by not bringing them to a
full charge state.
03F Max Charge Time:
The
Max Charge Time
setting is the maximum
time the charger will operate in either the Bulk or Absorption mode. Once
the charger reaches the max charge time, it will transition to the
fi
nal
charge stage as set in the SETUP menu’s
03G Final Charge Stage
.
Default setting
-
Max Charge Time = 12.0 Hours
Info:
In order to ensure a complete charge cycle is accomplished,
adjust the
Max Charge Time
setting to a higher value than the
settings in the following SETUP menu items;
03E Absorb Done
Time
,
03E Absorb Done Amps
, and
03E Absorb Done SOC
. The
Max Charge Time
setting has priority over these menus and will
stop the charge cycle once that setting is satis
fi
ed.
Example:
The
Max Charge Time
setting is six hrs, but the
03E Absorb
Done Time
setting is eight hrs. The charge cycle will stop after six hrs as
per the
Max Charge Time
setting, and not
fi
nish the
Absorb Done Time
setting of eight hrs.
03G Final Charge Stage:
The
Final Charge Stage
setting is the stage the
charger will transition to after the Absorption Charge stage is completed
(as set in the
03E Absorb Done
menu item). There are three choices for
the
fi
nal charge stage:
Multi-Stage
,
Float
, and
Silent
.
Info:
The
Final Charge Stage
menu item is only used when
Multi-Stage
is selected in the
02 CHG Control
menu item.
Default setting
-
Set Final Charge Stage = Multi-Stage
Set Final Charge Stage = Multi-Stage
-
The
Multi-Stage
setting
transitions from the Absorption stage to Float. Once in the Float stage
for four hours with no DC load on the batteries, the charger will enter the
Full Charge stage. In the Full Charge mode, the charger automatically
goes into a Standby mode (stops charging but is still on and active)
and monitors the battery voltage. The charger will remain in the Full
Charge stage until the battery voltage drops below 12.7 VDC for 12v
batteries, 25.4 VDC for 24-volt batteries, and 50.8 VDC for 48-volt
batteries – at which time it will return to the Float stage. These battery
voltages are the fully charged voltages of a battery at rest. The charger
will continue to cycle between Float and Full Charge as long as incoming
AC is available.
