When operating with a mains power supply, the internal battery
is automatically charged first. Once this has been charged
(lamp shows green), the external battery is automatically
charged.
Savina automatically detects the voltage of the external
battery (12 V or 24 V).
Once the respective battery is fully charged, trickle charging
takes place:
Savina charges the battery to counteract running-down.
Operation with an external battery or DC on-board network
In the event of a mains power failure, Savina seamlessly
switches over to the external DC power supply connected.
This may take either of two forms:
— Supply from external battery
or
— Supply from DC on-board network
Savina detects whether an external battery or the DC on-board
network is connected. This prevents Savina from charging the
DC on-board network.
