If battery modules without communication are used, the adjustment of general charging pa-
rameters must be tested and ensured for the specific battery module used.
Illustration 7: Compensation charging characteristic
Automatic temperature compensation can be disabled at any time via the configuration soft-
ware. A customized defined value can be saved for the maintenance charging end voltage.
Factory default charging setting
After the battery modules are detected with “Battery Control”, the following factory default
charging settings are assumed. Battery modules without “Battery Control” are charged in
factory default settings with a voltage of 27.4 V / 13.7 V in 24 V / 12 V operation and a
charging current of 0.8 A.
