The O2-CTRL STATUS (Oxygen Controller Status) menu displays the system air supply, oxygen supply, gas
flow, pressure and temperature related parameters. In BioTector, when the user enters the Oxygen Controller
Status menu or any menu, where the oxygen gas flow will be required, the oxygen concentrator starts to
operate automatically.
1. Identification. Identification is the specific identification number for the Oxygen Controller Board.
2. Version. This menu item specifies the software version of the Oxygen Controller Board.
3. Mode. This menu item allows the Oxygen Controller Board to operate the Mass Flow Controller (MFC)
only, the Oxygen Concentrator only, or both.
4. Temperature Sensor. This is the BioTector temperature sensor, located on the Oxygen Controller Board,
which displays the system temperature. The voltage (V) readings as obtained from the temperature
sensor are displayed in real time.
5. Air Pressure Sensor. This menu item displays the air inlet pressure for the oxygen concentrator. The
pressure (mbar) and the voltage (V) readings as obtained from the Air Pressure Sensor are displayed in
real time.
6. O2 Pressure Sensor. This menu item displays the oxygen inlet pressure for the Mass Flow Controller.
The pressure (mbar) and the voltage (V) readings as obtained from the Oxygen Pressure Sensor are
displayed in real time.
7. Valve 1, 2, 3. This item displays the Oxygen Controller valve outputs for valves 1, 2 and 3. Valve 1 is the
Air Isolation Valve. See figure 6 in Section
and 3 are reserved. When Valve 1 is activated, the displayed value is "1". When Valve 1 is deactivated,
the displayed value is "0".
8. Rotary Valve. This menu item displays the operation (Forward, Reverse and Stop) of the Rotary Valve.
9. Rotary Valve Sensor. This menu item shows the sensor position of the Rotary Valve. If the Rotary Valve
is on the sensor, the displayed value is "1". If the valve is not on the sensor, the displayed value is "0".
10. MFC Setpoint. This menu item allows the user to test the Mass Flow Controller. Use this function to set
the MFC setpoint. Press the ENTER key, set the required setpoint (e.g. 60 l/h), and press the ENTER key
again. The actual flow is shown at the top of the screen. An "*" is shown when the MFC has been
activated. If the flow is 0.0 l/h, then the MFC is switched off.
11. MFC Flow. When MFC Setpoint is programmed above, this menu item displays the actual flow and the
corresponding voltage on the MFC. When BioTector is not running, that is, when it is powered up and
stopped, or when it is in standby state, as the MFC Setpoint is 1 l/h, the MFC Flow displays the 1 l/h flow.
