3.6 Batteries
3.6.1 Internal battery
•
The device is fitted with an internal battery. If the device
is no longer connected to the power supply or there is a
power outage, the battery automatically starts supplying
the device without interruption. This discharges the
battery. This discharges the battery. The battery is
charged automatically again as soon as the device is
connected to the power supply.
In operation via a 12 V or 24 V supply, the battery is
charged only when the device is in the
Standby
or
Off
state.
•
The internal battery is replaced by the manufacturer or
by a specialist dealer.
•
Battery life depends on ventilation settings and ambient
temperature
(see “9 Technical specifications”, page 29)
•
When the
Battery capacity low
alarm appears, only a
minimum of 15 minutes’ life remains. When the
Battery
capacity critical
alarm appears, the device will switch
off in a few minutes’ time (less than 5 minutes’ life
remaining). Have an alternative ventilation option to
hand and connect the device to the power supply.
•
If device and battery have been stored outside the
quoted operating temperatures, the device can only be
started up once it has warmed up or cooled down to the
permitted operating temperature.
3.6.2 External batteries
•
External batteries can be connected to the device as an
additional energy supply. If the device is connected to
the power supply, the batteries are charged; first the
internal battery, then the external batteries. In operation
via a 12 V or 24 V supply, the batteries are charged only
when the device is in the
Standby
or
Off
state.
•
If the device is not connected to the power supply, a
battery powers the device. The external batteries
connected are discharged first, followed by the internal
battery.
3.6.3 Display of remaining device life
Remaining device life in the case of battery and power supply
operation is displayed in the status line and in the
Views
(see “5.2.1 Views menu in the Patient menu”, page
.
Remaining life is a prediction and always relates to the
current mean consumption of the device.
Following the start of ventilation, no more than 3 minutes
will elapse before remaining life is displayed.
3.7 Trolley 2.0
You can use the oxygen cylinder clamp with oxygen cylinders
up to 120 mm in diameter (this corresponds to a cylinder size
of approx. 4 l to 6 l per cylinder). Note total cylinder height
(cylinder including valve and accessories).
