S/5 Avance
Error Log Entry Alarm Text
Action/Troubleshooting
REVERSE EXPIRATORY Reverse exp flow.
FLOW Check valves OK?
Check flow sensor connections for "No Flow Sensor" alarm.
Check the breathing circuit.
Perform flow sensor calibration.
Check Insp/Exp check valves.
Replace the flow sensors.
Check for kinked VIB tubing.
Check the VIB cabling.
SCGO Vol and Apnea
monitoring off
No service action required.
STANDBY PATIENT No fresh gas flow!
DETECTION
No service action required.
VENT FLOW VALVE FAIL Vent Fail. Monitoring
DAC Only
Reboot System. If problem continues, in the Service Software / Vent Flow & Pressure Diagnosis,
increase the Flow Valve counts and view the Flow Valve Feedback mV and Counts. Verify the settings
match.
VENT +12.5V FAIL Vent Fail. Monitoring
Only
In the Service Software / Vent Interface Bd Power Diagnosis, view the "Vent Int Bd 10VA Voltage" from
Board Supplies:
If "Vent Int Bd 10VA Voltage" reads "OK, and +12.5 Vdc reads "Fail", replace the VIB.
If "Vent Int Bd 10VA Voltage" reads "Fail" and the "Vent Int Bd 10VA Voltage" from the Anes Cntrl Bd
reads "OK", Check cabling between ACB and VIB.
