f. Press SELECT to confirm the change, the value will stop blinking, and the change
is made final.
g. Press SETUP to return to the parameters menu. With the "-" or "+" button it is now
possible to scroll to another parameter that needs change.
h. To return to normal mode, press SETUP during 3 seconds.
1) Press SELECT: the text "" will blink, press SELECT again to reset to original
factory settings. The charger will re-boot. The history data will not be affected (kWh-
counter).
2).These values can ONLY be changed for the battery number 8 (User-defined battery).
The values in the table are for a 48V-battery.
3) Automatic equalisation can be set to "OFF" (default) or a number between 1 (every
day) and 250 (once every 250 days). When Automatic equalisation is active, the
absorption charge will be followed by a voltage limited constant current period (see
table 3). The text "equalize" will be on.
The current is limited to 8% of the bulk current for all VRLA (Gel or AGM) batteries and
some flooded batteries, and to 25% of the bulk current for all tubular plate batteries.
The bulk current is the rated charger current (85A) unless a lower maximum current
setting has been chosen.
If, as recommended by most battery manufacturers, the bulk charge current does not
exceed 20A per 100Ah battery capacity (i.e. 425Ah for a 85A charger), the 8% limit
translates to max 1,6A per 100Ah battery capacity, and the 25% limit translates to max
5A per 100Ah capacity.
In case of all VRLA batteries and some flooded batteries (algorithm number 1, 2 or 3)
automatic equalization ends when the voltage limit maxV has been reached, or after
t = (absorption time)/8, whichever comes first.
For all tubular plate batteries automatic equalization ends after t = (absorption time)/2.
When automatic equalisation is not completely finished within one day, it will not resume the
next day, the next equalisation session will take place as determined by the day interval as
programmed in the setup menu.
4) Press SELECT: the text "" will blink, press SELECT again to erase the history data
(kWh-counter, etc). Note that this takes a few seconds to complete.
5) Backlight automatic turn-off has the following options: OFF=backlight remains lit all the
time, ON=the backlight will dim 60s after the last keypress, AUTO=when charging the
backlight is lit, otherwise it will dim.
Warning
Some battery manufacturers do recommend a constant current equalization period,
and others do not. Do not use constant current equalization unless recommend by
the battery supplier.
