Table 6: Setup menu parameter details
a. To enter the SETUP Menu, press and hold the SETUP-button during 3 seconds. The
"Menu" icon will light up and a scrolling text is visible.
b. Press the "-" or "+" button to scroll.
c. Table 6 above lists in order of appearance all parameters which can be adjusted when
pressing the "-" button
d. Press SELECT: the parameter to change will now blink.
e. Use the "-" or "+" button to chose the desired value.
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 (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.
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.
