* If a mains power pack located outside of the power pack compartment (treated as an external power supply) is disconnected,
this will trigger the external power supply alarm, not the mains power alarm.
WARNING
In the event of a complete loss of power, or if the ventilator is shut down intentionally,
alarms will automatically stop after 120 seconds. You should check that this occurs by
performing the Power Supply alarm test (see page 74).
NOT013281-8
Priority Cause
High The pressure in the circuit is
higher than the High Pressure
alarm threshold
Low The patient's minute volume is
higher than the Maximum
Minute Volume alarm threshold.
High The patient's minute volume is
lower than the Minimum
Minute Volume alarm threshold
High The tidal volume is higher than
the upper threshold for the Tidal
Volume alarm
High The tidal volume is below the
lower threshold for the Tidal
Volume alarm
Priority Cause
Low The external battery pack is
disconnected
Low Loss of external DC power
supply
Low Abnormal expiratory resistance
in the patient circuit
Low Abnormal inspiratory resistance
in the patient circuit
Low No mains power pack in the
compartment under the device
or at the external power socket
Solution
Check the alarm threshold is correctly set and
the patient's airway is clear, and check the
integrity of the patient circuit
Check the alarm threshold is correctly set and
check the integrity of the patient circuit and
the expiratory valve function

the expiratory valve function
Check the alarm threshold is correctly set and
check the integrity of the patient circuit and
the expiratory valve function
Check the alarm threshold is correctly set and
check the integrity of the patient circuit and
the expiratory valve function
Solution
Reinstall the external battery pack or confirm
the disconnection by pressing the Alarm
Silence button
Check the external DC supply connection or
confirm disconnection by pressing the Alarm
Silence button
Change the patient circuit and perform the
manual test
