Chapter 1 Measuring principle The sensor measures the dierence in oxygen content between a reference and a sample gas. As reference gas normal ambient air is used with a oxygen content of 20,94%. The sensor consist of 4 main parts. Pumpingcel (3), nernstcel (4) heater (5) and diusion-chamber (6). The sample gas enters the diusion chamber. Based on the dierence in oxygen content of the gas in the reference chamber (2) and diusion chamber (6) a voltage is generated. When the oxygen content of both chambers is equal the generated voltage is 450 mv. The output of the dierential amplier (7) is zero in this case. When the oxygen content is not equal oxygen molecules can be added or removed by the pumping cell (3) In this case the output of the dierential amplier is not zero. The dierence is evaluated by the PID controller and sent to the pumping cell (3) The oxygen content is adjusted until the dierence is zero. The current to the pumping cell is a measure for the measured oxygen content and is indicated on the display (9). The reference air for the sensor is supplied through the wiring sleeve on the B4009Sxx sensors, therefore the wiring may not be obstructed. On the B4009Txx sensors the reference air is supplied through the metal casing. Pressure dierence between the sample gas line and the reference air supply will inuence the transport of oxygen molecules and therefore inuence the measurement. The measurement may be compensated for this pressure dierence. Figure 1.1: Schematic display of the oxygen sensor. Manual A4009T-O2 analyser R01-EN 3 / 33

Chapter 2 Safety The analyzer may only be installed and controlled by skilled personnel. Follow the instructions in this manual. Verify the electrical connections before applying power to the unit. The analyzer is only suitable for installation in a safe environment, the analyzer may not be installed in a explosion hazardous area unless sucient protection is in place. The analyzer is intended for the measurement of gas with low oxygen content. Gas with low oxygen content is dangerous to humans. It is necessary to make sure there is sucient ventilation while working with the analyzer. Manual A4009T-O2 analyser R01-EN 4 / 33

Chapter 3 Installation 3.1 Mounting 3.1.1 Analyzer. The analyzer housing is designed to be mounted inside a (control) panel. The control elements and display are easy accessible at the front, the wiring can be connected at the backside inside the panel. The analyzer shall be mounted in a clean place, away from dust, moisture and oil. The analyzer shall be mounted in a by maintenance personnel easy accessible location. The ambient temperature at the mounting location shall not exceed 50 C. 3.1.2 Sensor The sensor shall be mounted in the gas ow that needs to be analyzed. The mounting assembly M4009R01 can be used for mounting the sensor. The sensor shall be placed in a sucient ventilated area as the reference air for the sensor is the surrounding air. The measurement accuracy may be inuenced when sucient ventilation is not available. The sensor will be hot during operation. it may be necessary to provide a heat shield to protect personnel. The sensor must be mounted in a 90 degree angel to the gas ow see gure 3.1. To prevent moisture entering the sensor the sensor shall be mounted straight upwards if possible. If this is not possible the sensor may be mounted in an angle of maximum 80 degrees to the vertical, as shown in gure 3.2. The sensor must be protected from water. The sensor cable shall be mounted stress free as this is the supply for reference air to the sensor. The sensor may not be connected to a power supply other then the analyzer as this may damage the sensor. Manual A4009T-O2 analyser R01-EN 5 / 33

3.2. ELECTRICAL CONNECTIONS 3.2.1 Power supply The power supply shall be connected to terminal 1 (+) and 2 (-). A stabilized DC supply of 24 VDC is required for reliable operation of the analyzer. The power supply shall be capable of delivering at least 1,3 Ampere. 3.2.2 Relays The analyzer consist of 5 relay contacts, 3 changeover contacts and 2 normally open contacts. All relay contacts are fail-safe, this means the relay is energized when there is no failure. In case of a failure the relay will be deenergised. Both normally open contacts serve a double function. When automatic calibration is selected the contacts are used to control the calibration gas valves. When automatic calibration is disabled the contacts are used for the high and low oxygen alarms. More information about calibration can be found in chapter 7 3.2.3 Analog Outputs The analyzer is equipped with 2 independent analog 4-20mA outputs. Figure 3.4: Connection diagram for Analog output 4-20mA Both analog outputs are passive, a power supply shall be attached to operate the outputs. The analog outputs represent the measured oxygen content. The range can be selected through the settings menu. see 4.2.3.2 3.2.4 Digital inputs The analyzer is equipped with 2 digital inputs. The inputs can be activated by connecting a 24VDC power supply. Digital input 1 activates the alarm suppression function. When the input is high the alarms are suppressed. Digital input 2 activates the automatic calibration routine. 3.2.5 Sensor The sensor is connected to the analyzer by means of the connection cable K4009A01. There are 2 types of sensors which shall be connected in dierent ways. The type of sensor is indicated on the sticker on the sensor. Connection of B4009S01 and B4009S02 sensor.

4.2. SETTINGS 4.2.3.2 Analog Output The analog output represents the measured oxygen content as a current from 4 to 20 ma. This current can be evaluated by a display, controller, recorder, PLC or DCS system, in order to monitor the oxygen content in a remote location. The connected equipment shall be congured so the measured oxygen content is equal to the settings in the A4009T oxygen analyzer. Figure 4.3: Analog output characteristic Based on the settings for 4 ma (MIN) and 20 ma (MAX) the A4009T oxygen analyzer will calculate the current supply to the 4-20 ma loop based on the measured oxygen content.

Chapter 5 Maintenance 5.1 Analyzer The analyzer does no require much maintenance. The control panel shall be cleaned regularly with a soft cloth. 5.2 Sensor The sensor does not require a lot of maintenance during it's life span. Check the sensor for contamination and clean if necessary. In case of severe contamination the sensor shall be replaced. Check the wiring to the sensor, check if the protection sleeve to the wiring is not pinched as this is the reference air supply to the sensor. 5.3 Calibration Depending on the usage, the analyzer need to be calibrated regularly. Before calibration is started the sensor need to be heated at a stable temperature. "Zero Calibration" shall be done with a gas mixture with certied composition. "Span gas" shall be instrument air with 20.94% oxygen; (Normal ambient air) The pressure for the "Zero" and "Span" gas shall be equal to the measured gas. 5.3.1 Setting Zero Gas and Span Gas 5.3.1.1 Zero Gas The oxygen concentration in the zero gas shall be set prior to calibration.

Chapter 7 Automatic Calibration The automatic calibration allows for periodic calibration of the analyzer without human interaction. In this way the it is guaranteed the analyzer measures correctly. 7.1 Installation. To use the automatic calibration function 2 extra valves are required to switch on and o the span and zero gas supply to the sensor. Also an electrical 24VDC signal is required to start the automatic calibration procedure.
