Instructions for use Fabius plus SW 3.n
Power supply failure
Mains power supply failure
If mains power fails, Fabius automatically switches
to the internal battery. With a fully charged battery
the supply of the ventilator and the internal monitor
functions are maintained for up to 2 hours.
The remaining battery charge is displayed in the
status bar.
The operating time of the battery depends on the
ventilation settings and the condition of the battery
(age and battery charge). A completely charged
battery can ensure supply for at least 45 minutes.
In battery operation and in case of decreasing
battery charge, the following information is
displayed:
– The battery symbol
is displayed in the
status bar and the LED indicator for mains
power supply goes out.
– The note
POWER FAIL !
is displayed in the
alarm window.
– When the remaining battery charge drops
below 20%, the note
BATTERY LOW !
is
displayed in the alarm window.
– When the remaining battery charge drops
below 10%, the note in the alarm window is
replaced by the alarm
BATTERY LOW !!
.
– Shortly before the battery is empty, the
ventilator is switched off and the alarm
VENTILATOR FAIL !!!
is displayed in the
alarm window.
– If no manual ventilation follows, the following
alarm messages are displayed:
–
APNOEA PRESSURE !!!
–
APNOEA FLOW !!!
–
MINUTE VOLUME LOW !!
The monitoring functions remain in operation until
the battery is completely discharged and all
electronic components are switched off.
CAUTION
Risk of device malfunction
If mains power fails, devices connected to the
auxiliary power sockets are not supplied from the
internal battery.
Ensure an alternative power supply for
connected devices.
WARNING
Insufficient ventilation of the patient
If the alarm message
BATTERY LOW !!
(remaining battery charge 10%) is displayed
for the first time, the ventilator still remains in
operation for up to 10 minutes.
Restore mains power supply. Afterwards, the
automatic ventilation is available again.
WARNING
Risk of patient injury
When the battery is empty, Fabius switches
off automatically.
Never completely discharge the battery.
However, if there is a complete discharge of
the battery, charge the battery immediately.
The device must not be used until the battery
is completely charged again.
