TROUBLESHOOTING
PROBLEM
CAUSE
SOLUTION
Medical gas alarm
The device is not connected to a medical gas
supply
Connect the device to a medical gas supply
The oxygen tank is exhausted
Replace with a new tank and prepare the old one for filling
procedures
The delivered pressure is not sufficient (less than
2,8 bar)
Verify the oxygen supply , or verify the performance of the
pressure reducer by the manufacturer
The patient can’t breath
The patient valve is not correctly positioned or is
damaged
Verify that the patient valve is correctly positioned or replace it
Low Paw (airway pressure)
Non-rebreathing valve is not correctly connected
to the tube or to the mask
Verify the proper assembly
High pressure alarm
The airways are obstructed
Ensure that implants have been removed ; carry out
bronchoaspiration
The corrugated tube is bent
Verify the corrugated tube
Patient is not hyperextended
Hyperextend or use Guedel or Berman cannulas
High pressure limit is set too low
Adjust the high pressure limit 10 mbar over the airway pressure
Low battery
Internal battery with an autonomy less than 20
min
Recharge immediately the internal battery. If the problem
persist, replace the battery.
Apnea
There is not spontaneous breathing
Re-evaluate the patient’s clinical condition. If necessary, select
the CMV or A/CV ventilation mode and verify that the breathing
circuit is free from obstructions
The low battery alarm doesn’t work
The 9V backup battery is discharged
Replace the backup battery
The manovacuometer doesn’t indicate
“0” when the ventilator is not working
The component is damaged
Put the device out of service and contact an authorized service
center
Is not possible to recharge the battery
The electrical power source is not stable
Verify the power source. If anomalies are present, contact an
authorized service center
The battery has reached its life limit
Replace the battery
The fuse is blown
Replace the fuse as described in the manual
The device is not working
Low voltage has caused a microprocessor failure
Verify the voltage of the power supply. Turn off the device and
turn on again. If the problem persists, contact a Service center
Turning on the device it does not start
the controlled ventilation
Failure to electrical or pneumatic supplies or a
failure of the device has occurred
Check for visual or acoustic signals as described in this manual.
If no signal is present, put immediately the device out of service
and contact an authorized service center
The trigger doesn’t work properly
Low voltages have caused improper operation of
components of the device which reads incorrect
pressure values of the patient circuits
Verify the voltage of the power supply. Turn off the device and
turn on again. If the problem persists, contact a Service center.
The quick connector for the input of the
medical gas is not stable
Quick connector damaged or worn
Put the device out of service and contact an authorized service
center
Noises occur caused by vibrations when
driving the medical vehicle
Constant stresses caused a deterioration of the
fasteners or mating surfaces
Ask your installer to check that the conditions for the
installation have been met
The device does not turn on
Anomalies of the internal electronic circuit
Put the device out of service and contact an authorized service
center
Software failure
Internal error o power supply problems
Restart the device. If the problem persist or happens frequently,
put the device out of service, check the electrical power supply
and contact the manufacturer.
Flashing of one or more lights inside the
bar used to monitor breathing phases
Internal component failure
Put the device out of service and contact an authorized service
center
LED LOW BATT flashes every 5 seconds
with short acoustic signal
The main battery is fully discharged or is damaged
Recharge the battery or replace it. If the problem persist, put
the device out of service and contact an authorized service
center.
