Current readout gives wrong polarity
(current should positive when charging and
negative when discharging the battery)
•
Shunt installed in reverse. Make sure that the
‘Battery –‘ bolt is connected to the battery
negative terminal and the ‘System –‘ bolt to
the battery loads.
No changes can be made in the Function
setup menu (the text ‘Locked’
appears when
trying to change a value
•
The battery monitor is locked by the installer.
Please see chapter 8 for more details.
State of Charge or Time remaining readout
not accurate
•
Check if all current is flowing through the
shunt (the negative terminal of the battery
may only contain the wire going to the
‘battery –‘ side of the shunt!)
•
Shunt installed in reverse. Make sure that the
‘Battery –‘ bolt is connected to the battery
negative terminal and the ‘System –‘ bolt
to
the battery loads.
•
Check if all battery properties (F1.x) are
correctly set
•
Check if the battery monitor is synced with
your battery. Perform full charge cycle.
Display returns ‘
- -.-
‘ in temperature readout
•
Connection with the temperature sensor is
lost. Check sensor cable.
The monitor resets all the time
•
Check wiring for corrosion or bad contacts
•
Battery might be flat or defective
The monitor does not automatically
synchronize
•
The battery is not reaching its fully charged
state. Please check if the charge algorithm
matches the requirements of your battery. Do
not interrupt the charge process before it is
finished.
•
Consider setting Advanced Function A01 to
‘LEGACY’ and tweak Functions A02 –
A05 to
better match it to your system.
The monitor synchronizes too early
•
In some systems (like solar) the charge current
can fluctuate heavily, causing the battery
monitor to consider the battery fully charged
too early. In this case, Function A01 can be set
to ‘LEGACY’ and Function A02 approx. 0.2V
-
0.3V below the absorption voltage.
