Troubleshooting
12.1.2 Systematic localization of leakage
To find causes for leakage, isolate individual components from the leakage test.
1. Perform the leakage test, see page 112.
If necessary, perform the manual check for leaks or use the leakage assistant.
2. Contact service personnel if the leakage cannot be localized.
12.2 Power supply failure
12.2.1 Mains power supply failure
If mains power supply fails, the device automatically switches to the internal battery.
A fully charged battery will maintain operation for at least 45 minutes. For further
information see: "Technical data", page 272.
Remaining battery charge is displayed on the status display.
The breathing system warmer is deactivated during battery operation. The peak
inspiratory flow may be limited.
12.2.2 Mains power supply failure and battery discharged
If mains power supply fails and the battery is discharged, a signal tone is emitted.
Manual ventilation and spontaneous breathing are still available. O
2 and anesthetic
agent can still be delivered using the emergency O
2 delivery (with electronically
controlled gas mixer) or the flow control valves (with mechanically controlled gas
mixer) and the vaporizers.
The following components and functions are not available:
– Ventilator
– Electronically controlled gas mixer
– Device monitoring and patient monitoring
WARNING
Risk of patient injury
If all power sources fail, the screen goes dark and mechanical ventilation ends.
► Ventilate the patient manually.
Component Measure
Sample line Remove the sample line and seal the Luer-Lock connector
on the Y-piece.
Breathing hoses Disconnect the breathing hoses. Connect the inspiratory
port and expiratory port with a hose that is known to be with-
out leakage. Connect the breathing bag directly to the
breathing system.
Vaporizers Remove the vaporizers.
O
2 sensor Remove the O2 sensor. Seal the sensor port with the sealing
cap.
