Service Code Alarm Name/Mitigation/Resolution
3011 O2 Valve Fault
The signal to the O
compressor is available to provide ventilation, and the operator has acknowledged that ventilation
is being provided using the compressor by setting the FIO
Mitigation/Info: Compressor Operation Only!, Keep FIO
SpO2
**Replace/Service Ventilator**
3012 O2 Valve Fault
Communication between the O
ventilation, and the operator has set the FIO
Mitigation/Info: Operation Switched to Compressor!, Keep FIO
Monitor SpO2
**Replace/Service Ventilator**
3032 Fresh Gas Intake Fault
Communication between the Fresh Gas/Emergency Air Intake pressure sensor is lost. Normal
operation will continue, but if the condition is not cleared by powering off and restarting, the unit
should be send for service. When used during this alarm condition, the operator should be sure to
keep the Fresh Gas/Emergency Air Intake clear and assure that external filters are checked
regularly.
Mitigation/Info: Intake Pressure Sensor Failure, Unable to Detect Filter Obstruction
**Replace/Service Ventilator**
3041 O2 Supply Pressure High
The oxygen supply pressure is
supply pressure drops below 66 psig. Pressures above 80 psig could result in a catastrophic failure,
harm to the patient, and/or damage to the unit.
Mitigation/Info: Decrease O2 Supply Pressure, Replace Regulator, Connect Low Flow O2, Monitor
SpO2
**Monitor O2 Supply Pressure**
3110 RTC Battery Fault
The real-time clock (RTC) battery is < ~2.5 volts.
Mitigation/Info: RTC Battery Low, Schedule Service Immediately
**Replace/Service Ventilator**
3120 Self Check Fault
Start up when the preselected number of days has elapsed from the last calibration. Calibration is
due every 365 days or 1500 hours of service.
Mitigation/Info: Calibration Due, Schedule Service Immediately
**Replace/Service Ventilator**
3130 Ambient Pressure Fault (Excessive Altitude Sensor Failure)
The ambient pressure transducer fails. When this occurs, the unit is no longer able to automatically
compensate for changes in altitude especially in situations where the ambient pressure could
change rapidly as during air transport.
Mitigation/Info: Barometric Pressure Sensor, Altitude Compensation Disable, Maintain Airway
Pressure, Check Patient Chest Rise, Avoid Use At Varying Altitude
**Replace/Service Ventilator**
