SECTION 2—INSTALLATION/SEQUENCE OF OPERATION
After five minutes, if the oxygen purity exceeds 85% ± 2%, the GREEN light will continue
to illuminate.
If the oxygen level is not above 85% ± 2% after the first five minutes, the system will
continue to monitor the O
and wait for a maximum of 30 minutes from start‐up to reach
2
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.
During operation 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.
