Troubleshooting
Further procedures:
1. Check the vaporizer setting.
2. Electronically controlled gas mixer:
Use the emergency O
2 delivery, see page 50.
Mechanically controlled gas mixer:
Close the flow control valves for Air and N
2O. Use only O2 as fresh gas.
3. Electronically controlled gas mixer:
Monitor the O
2 flow with the O2 flowmeter.
Mechanically controlled gas mixer with electronic flow measurement:
Monitor the O
2 flow on the total flow tube.
4. Check the setting of the APL valve.
5. Ventilate the patient manually.
6. Ensure corresponding substitute monitoring.
12.2.3 After power supply is restored
1. Restart the device, see page 104.
2. Charge the discharged battery for at least 8 hours.
3. Using the information displayed on the gas mixer unit, check that power is
supplied.
12.3 Failure of the gas supply
12.3.1 Failure of the central gas supply system
A failure of the central supply can result in simultaneous device malfunctions on all
systems connected to it.
Devices that are equipped with gas mixers with electronic flow measurement
generate corresponding alarms in the event of failure of the central supply for the
gases O
2, Air or N2O.
The alarm for N2O is only generated if N2O is configured accordingly.
With devices that are equipped with gas mixers with flow tubes, failure of the central
supply is indicated by the pressure gauges for the gas supply on the gas mixer unit.
If the central supply fails, gas supply for the device can be performed temporarily by
the connected gas cylinders. On devices that are equipped with Advanced Cylinder
Support, this takes place automatically when the gas cylinders are open.
Otherwise, proceed as follows:
● Open the corresponding gas cylinder valve.
● Re-establish the central supply.
