FIGURE 24.2
Oxygen Sensor
Alarm sequence occurs when concentration levels fall below a preset value, typically 73%
± 3% or 85% ± 2%. This failure indicates a catastrophic failure of any component
mechanical or electrical.
Oxygen Sensor Test
1. Turn unit on
. Set output flow at 5 L/min. for 5 Liter models and 9 L/min for 9 Liter
models.
2. Monitor the O
2
level.
3. With the O
2
level greater than 85% after five minutes, the GREEN
panel indicator light
will remain illuminated.
4. Slowly adjust flow beyond maximum rated flow until you can achieve a concentration
level greater than 75% but less than 84%. Within 30 minutes the YELLOW
panel
indicator light will illuminate and the unit will continue to run.
5. Clamp off the 1/8-inch oxygen sensor tubing between the oxygen sensor and the
product tank regulator.
WARNING
Use care not to cut oxygen sensor tubing when clamping the oxygen sensor tubing.
6. Within 30 minutes, the Oxygen Sensor Alarm should activate and the RED panel light
indicator will illuminate. The compressor will shut down with the alarm.
