High TC readings at the end of TC
phase, even though the TC time has
been automatically extended to its
maximum time of 300s. See Section

Reaction Check
Air pressure supply has been more
than 2.0 bar for longer than 5 seconds.
When the oxygen concentrator is
running, the pressure typically cycles
from 1.5 bar to 0.9 bar.
If system does not detect the air
pressure drop to normal levels, the air
supply is isolated from the system and
oxygen is not generated.
Air pressure supply has been more
than 1.8 bar for longer than 60
seconds.
When the oxygen concentrator is
running, the pressure typically cycles
from 1.5 bar to 0.9 bar.
Air pressure supply has been less than
0.6 bar for longer than 5 seconds.
When the oxygen concentrator is
running, the pressure typically cycles
from 1.5 bar to 0.9 bar.
If system does not detect the air
pressure increase to normal levels, the
air supply is isolated from the system
and oxygen is not generated.
