please change this in Function F1.2 (see chapter 6.1) afterwards. Once the selection has been
made, press the MENU key for 3 seconds to nalize the Setup wizard.
If you wish to make any changes to the Main battery type or capacity afterwards, you
can always edit Functions F1.0 and F1.1 (see chapter 6.1).
The Setup wizard does not include any con guration steps for battery banks connected
to the B2 and B3 inputs. If your system does include a second or third battery, please
con gure these manually using Functions F2 and F3 (see chapter 6.2 and 6.3).
After the Setup wizard has been completed, the ePRO Plus will take a few seconds to analyze
your battery and estimate the nominal battery voltage as well as the current State of Charge (%).
The State of Charge readout will show a small animation while it is calculating.
When a lithium battery type is selected, only the nominal battery voltage will be
estimated. A start value for the State of Charge is not given yet and represented by
‘- - %‘. A complete charge cycle is needed to obtain the exact State of Charge value.
For the highest accuracy, it is important that the battery is not being charged or
discharged during this analysis time!
When your battery system has a nominal voltage level other than listed in table 2, you need to
manually change this in Advanced Function A07.
Table 2 shows how the ePRO Plus determines the nominal voltage of your battery bank. This
table is valid for all three battery bank inputs. Please note however, that B2 and +B3 do
not support LiFePO4 batteries. As you can see in table 2, the estimated number of battery cells
are also mentioned. Except for individual 2V lead- or 3V Lithium cells, all batteries contain a
number of internal cells in series. A 12V lead acid battery for example, contains 6 cells internally.
The ePRO Plus needs to know the number of cells, since its calculation algorithms are cell based
for optimal accuracy.
