1) Press SELECT for 4 seconds to reset to original factory settings. After 4 seconds the
charger will re-boot. (The kWh-counter will not be affected).
2).These values can ONLY be changed for the battery number 8 (USr) (User-defined
battery). The values in the table are for a 48V-battery.
3) When Automatic equalisation is "ON", 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 (70A) 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. 350Ah for a 70A 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.
4) Press the"-" button for 3 seconds to reset to zero. Confirm by pressing SETUP.
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.
