Set Absorb Done (SOC) – This setting can be used if a battery moni-
tor kit is installed, and you want to use the SOC (State of Charge) of
the battery bank to determine when the batteries are fully charged. The
SOC is the best way to determine when the batteries are fully charged.
The SOC also is helpful because any DC loads or other charge sources
connected to the battery bank will not affect the SOC reading, and the
batteries will always receive a full charge.
Default setting: Absorb Done SOC = 100%
Range: 50-100%
Info: A ME-BMK is required in order to use the Absorb Done SOC
setting. If the Absorb Done SOC setting is selected and there is no
ME-BMK installed in the system, or if a valid SOC number is not
displayed under the METER/04 BMK Meters/04B SOC menu (i.e.,
Think'n, No Comm, Pwr-up Fault are not valid SOC numbers), then
the charger will immediately go to the Float Charge stage once the
Bulk Charge stage is fi nished.
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% set-
ting is sometimes considered an ineffi 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 a safety fea-
ture that ensures abnormal conditions will 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 or
Absorption Charge mode. If the charger reaches the maximum charge
time setting, it will transition to the fi nal charge stage as set in the SETUP
button's 03G Final Charge Stage.
Default setting: Max Charge Time = 12.0 Hrs
Range: 0.0-25.5 Hrs
Where should I set my Max Charge Time? In order to ensure a complete
charge cycle is accomplished, adjust the Max Charge Time setting to a time
period that will normally be longer 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 satisfi ed.
Example: The Max Charge Time setting is six hours, but the Absorb Done
Time setting is eight hours. The charge cycle will stop after six hours as per
the Max Charge Time setting, and not fi nish the Absorb Done Time setting
of eight hours.
