Senso Alarm Indicators - Invacare Perfecto2 IRC5PO2AW Service Manual

Invacare® Perfecto₂™ Oxygen Concentrator
If the oxygen level is not above 85% ± 2% after the first five minutes, the system will continue to monitor the O
30 minutes from start-up to reach 85% ± 2% before activating an alarm. Environmental factors such as low voltage, high altitude, or age
of the machine will affect the time required to reach 85% ± 2%.
If the oxygen level is not above 85% ± 2% within the first 30 minutes, the oxygen concentration alarm sequence will activate and the unit
will shut down.
When oxygen concentration is above 85% ± 2%, the sensor measures oxygen purity every 10 minutes. If a reading falls below 85% ± 2%, a
YELLOW light will illuminate. If the oxygen purity falls below 73% ± 3% the RED light/Alarm/Shut-Down mode will activate.
