The operating time with the internal battery depends on the
state of charge:
With a new, fully charged battery the operating time for typical
ventilation is about 60 minutes.
After about 25 minutes’ operating time, a caution message
is displayed:
!! Int. battery low
● Immediately reconnect to mains power supply
or
● connect to a charged external battery or the DC on-board
network.
At the end of the operating time, a warning message is
displayed:
!!! Int. batt. almost discharged
● Immediately reconnect to a power supply from the mains or
a charged external battery or from the DC on-board network
to prevent any interruption to ventilation.
After operating the Savina with an internal battery:
● Reconnect Savina to the mains voltage in order to charge
the internal battery and, if applicable, the external battery
again immediately.
When the power source is an external battery, the internal
battery is not charged. Only trickle charging takes place.
When the power source is the DC on-board network,
the internal battery is charged.
The charging time is around 5 hours.
● Always ensure the internal battery is charged from the
mains or from the DC on-board network. The internal
battery supplies the two O
2 sensors with current even when
Savina is switched off. This enables Savina to supply valid
O
2 measured values as soon as it is switched on. If the
internal battery is discharged, Savina does not supply any
O2 measured values for the first 20 minutes after switching
on, and the O
2 mix operates at reduced accuracy during
this time.
