3.1 Introduction
The SERVO-s Ventilator System is equipped
with an AC power supply with automatic range
selection. The ventilator will automatically
operate correctly using 100-120V AC or
220 - 240V AC outlets.
See chapter Technical data on page 147.
The ventilator is equipped with battery
modules which automatically supply 12V DC
power in the event of an AC power failure,
ensuring that ventilator settings and stored
data remain intact.
The ventilator also comes equipped with an
inlet for an external 12V DC power supply. This
power supply activates automatically in case
of an AC power failure, and ventilator settings
and stored data remain intact.
Two fixed battery modules are installed,
providing one hour of back-up operation.
When the system is connected to an external
power supply, all connected battery modules
are being recharged. This does not affect
ventilation.
Alarms and Messages
See Alarms and Safety on page 40.
When the ventilator is turned off with the on/off
switch, batteries continue to charge.
3.2 Viewing battery status
When operating from batteries, the estimated
remaining battery time in minutes is displayed
in the upper right corner of the screen on the
Status touchpad.
WARNING! If the remaining battery time on
the Status touch pad is displayed in red,
the battery modules have very little
operational time left and battery modules
must be replaced. If possible, connect the
ventilator to AC power.
Note: The total usable backup time is the
sum of the estimated operation time
displayed for each battery module minus
10 minutes.
Detailed battery status information is available
via the Battery Status Window:
1. Press the Status touchpad at the top-right
of the user interface to display the Status
Window.
