If the external battery is discharged or if no DC on-board
voltage is available, the device switches over to the internal
battery and displays the message:
!! Int. battery activated
● Acknowledge message = press »Alarm Reset« key.
The following advisory message is displayed:

The operating time with an external battery depends on the
state of charge and type of battery connected:
With a fully charged 24 V battery with 17 Ah, the operating
time is about 7 hours.
Savina detects when the external battery is discharged and
switches over to the internal battery.
When a mains voltage becomes available again, Savina
automatically switches over to mains power supply, charging
the internal battery first and then the external battery.
● Immediately reconnect Savina to mains power supply to
fully recharge the internal and external battery again.
Operation with the internal battery
In the event of a mains power failure, if no external battery is
connected or if the external battery is discharged, Savina
seamlessly switches over to the internal battery.
