3. Electric current flowing through a metal film resistor heats the disk in excess of 300 C Oxygen molecules contact the electrode of the disk and pick up extra electrons to become oxygen ions These oxygen ions are attracted to the electrode on the bottom of the zirconia sensing disk Because of the crystal structure of the zirconia only oxygen ions can pass through When the oxygen ions reach the bottom electrode the extra electrons are released from the oxygen ions and oxygen molecules return to the air The number of electrons is directly related to the oxygen concentration The electrons travel to the P C board where they are counted and the oxygen concentration reading is calculated A microprocessor on the P C board contains software that interprets the signal being received from the sensor It compares the signal to clinically acceptable limits Signals outside of the clinically acceptable limits generate responses in the form of lights audible indicators and or system shut down Operating Sequence Once the power switch has been turned on I the SensO circuit will wait five minutes for the concentrator to begin producing clinically acceptable oxygen and the oxygen sensor to stabilize The GREEN light will illuminate indicating normal system operation while the oxygen sensor is warming up After 5 minutes if the oxygen purity exceeds 85 2 the GREEN light will continue to illuminate Part No 1118396 15 Platinum Oxygen

No 1118396 SECTION 2 INSTALLATION SEQUENCE OF OPERATION The electrical activation of the 4 way Valve is accomplished every 8 to 15 seconds by the pressure sensor and P C Board electronics when the pressure reaches a set point of 144 79 kPa 21 psi for 5 Liter and 172 36 kPa 25 psi for 9 Liter The time between cycles is dependent on altitude flow rate and internal environmental factors A valve opens just prior to the shift of the 4 way valve This allows highly concentrated oxygen to enter the just exhausted bed from the top This additional pressure allows the bed to start its cycle at a higher pressure The P E valve will close just after the shift of the 4 way valve If main power is lost the Battery Free Power Loss Alarm will sound a short with a long pause after All units are equipped with a diagnostic alarm system that signals if the pneumatic pressure or electrical systems malfunction The Troubleshooting Guide in this manual explains the alarm system signals and reasons in detail for your convenience SensO Oxygen Sensor Technology Ceramic Zirconia Sensor Technical Description The oxygen being produced by the concentrator flows out of the product tank and into the flowmeter A small flow of oxygen produced by the unit is sent through a precision orifice to the oxygen sensor mounted on the printed circuit board As the oxygen enters the sensor it passes through a screen and contacts the sensing disk
