to activate the setup-mode first. The setup-mode can be activated by
pressing the SETUP key for three seconds. The display will blink to
indicate that the setup-mode is active. By repeatedly pressing the
SETUP key the desired Function can be selected. The selected Function
is represented as
Fxx
where
xx
indicates the Function number. The <
and > keys can be used to alter the value of the selected Function. By
pressing the SETUP key again, the next Function will be selected. To
save the changed settings to the SBM-01 memory, the SETUP key must
be pressed for three seconds until the display stops flashing and the
battery monitor jumps back normal operating mode again. If the SBM-01
operates in the setup-mode and not a single key is pressed for 90
seconds, the monitor will jump back to normal operating mode
automatically, without saving eventually altered settings.
The table below gives an overview of all SBM-01 Functions including a
short description. It is recommended not to change the Functions F04,
F05, F06, F09, F10, F11, F12, F13, F14, F15, F16, F17, F18 and F20
when in doubt. For most battery systems, only adjusting the values of
Functions F01, F02, F03, F07 and F08 should be sufficient.
F01 : Battery capacity in Amphours (Ah). This must be the capacity
at a 20h discharge rate and 20 °C (or 68°F).
Default :
200Ah
Range : 20 – 2000Ah
Stepsize : 1Ah
F02 : Voltage-charged-parameter. The battery voltage must be
above this voltage level to consider the battery as fully
charged. Make sure the voltage-charged-parameter is always
slightly below the voltage at which the charger finishes
charging the battery (usually 0.1V or 0.2V below the ‘float’
stage voltage of the charger).
Default :
13.2V
Range : 8.0 – 33.0V
Stepsize : 0.1V
F03 : Current-charged-parameter. When the charge current value is
below this percentage of the battery capacity (see F01), the
battery can be considered as fully charged. Make sure the
current-charged-parameter is always greater than the
minimum current at which the charger maintains the battery,
