SECTION 2—INSTALLATION/SEQUENCE OF OPERATION
SECTION 2—INSTALLATION/
SEQUENCE OF OPERATION
Installation/Verification of Battery Free Power Loss
Alarm
When your new Platinum concentrator arrives, it should be checked for proper operating
conditions.
1. If the unit has been in below-freezing temperatures, allow it to warm up to room
temperature before operating.
2. The concentrator may need to be turned on for 4 to 5 seconds to charge the Battery Free
Power Loss Alarm. Connect power cord to outlet and turn the concentrator on. Turn
flow control knob counterclockwise and flow will begin IMMEDIATELY. Set flow rate
to five L/min. Let the unit run for 30 minutes, then turn unit off.
3. Unplug the power cord and press on/off (I/O) switch to the On ( ) position. An
intermittent audible alarm will sound. This confirms proper operation of the Battery
Free Power Loss Alarm. Turn On/Off (I/O) switch Off (O).
4. Connect power cord to outlet and turn on concentrator. Unit will beep on start-up.
5. Check the oxygen concentration per specifications after 30-40 minutes running time.
Sequence of Operation
Turning on ( ) the power switch applies 230 VAC to the compressor motor, hour meter,
transformer, cooling fan and the printed circuit (P.C.) board.
Room air enters the compressor via the cabinet filter and the compressor inlet filter. The
air is compressed by the wobble pistons in the compressor to a pressure of 144.79 kPa (21
psi) for 5 Liter model and 172.36 kpa (25 psi) for 9 Liter model.
As increased pressure creates increased temperature, a heat exchanger is used to lower
the temperature before the air enters the 4-way valve. It is then channeled to a sieve bed
containing the adsorption material. Restriction downstream of the sieve bed causes
pressure to build up inside the sieve bed which is necessary for the adsorption process. A
small amount of relatively pure oxygen enters the top of the second bed through a
restrictive leak in the pressure equalization (P.E.) valve with the balance entering a storage
tank. The nitrogen removed is exhausted back from the bed through the 4-way valve into
room air. A muffler is located at the exhaust end of the valve to muffle the sound of the
exhaust as it exits the concentrator.
The oxygen not being used to exhaust is channeled into the storage tank. The pressurized
oxygen is regulated down to 34.5 ± 3.45 kPa (5 ± 0.5 psi) for 5 Liter; 62.05 kPa ± 3.45 kPa (9
± 0.5 psi) for 9 Liter, enters an accurate flow-measuring device, flows through Outlet
HEPA filter and check valve, then out to the patient.
Platinum™Oxygen
14
Part 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 P.E. 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 BEEP, 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.
SensO2 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.
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 ( ) , the SensO2 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
SECTION 2—INSTALLATION/SEQUENCE OF OPERATION
If the oxygen level is not above 85% ± 2% after the first five minutes, the system will
continue to monitor the O2 and wait for a maximum of 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.

CAUTION
Only qualified service technicians should make any changes to this equipment.
Follow these pre-cautions to prevent damage to the P.C. boards:
Before handling any P.C. boards, you need to be properly grounded to prevent
static damage to the components of the board. A Static Cuff MUST be worn and
properly grounded using an alligator clip. Electrical conduit or a water pipe is
normally sufficient when a known good ground is not available. Care should be
taken to ensure that the alligator clip contacts with bare metal surface.
When removing quick disconnects terminals, DO NOT pull on wire itself as damage
to the connection may occur. Hold down the P.C. board with one hand and use an
