Introduction 5.1 Analyser model The Oxygen analyser type PMA100 is produced by M&C Products Analysentechnik in Ratingen, Germany. 5.
-5- 6. Application The transducer of the PMA100 works at a stable temperature of +55°C. Therefore the analyser is suitable for continuous measurements of oxygen concentrations in particlefree and dry sample gases. Safe operation, reliability and minimized maintenance are the characteristic of the PMA100.

The calibration gases are given to the ‘sample in’ connection, located on the back panel of the PMA100 (see 8.1, fig. 7). In case of autocalibration two respectively three valves are controlled by the analyser menu. The connection of the calibration valves is described in chapter 8.2.

- 29 Example : The residual oxygen percentage should be measured in a closed 100% carbon dioxide (CO2) atmosphere. The „zerocalibration“ is done by means of Nitrogen (N2). According to the list of cross-sensitivities the error for CO2 at 20°C is -0,27%. In order to obtain a higher accuracy this means for the calibration that the reading should be adjusted at +0,27% with N2, in order to compensate the error of CO2. Since the values of cross-sensitivities are based on 100 Vol.
- 30 - 14.Measuring The connections for sample gas inlet and outlet are located on the back panel of the PMA100 oxygen analyser (see 8.1). A detailed description of the menu-driven handling is given in chapter 12. Note! The oxygen analyser PMA100 is suitable for continuous measurements of oxygen concentrations in particle-free and dry sample gases. Therefore it is recommended to use a gas conditioning system downstream the analyser equipped with a cooler and a particle filter. Meas. range 1 0 - 50Vol.
- 31 - 15.Function of in- and output contacts and alarms The following in- and output contacts are available at the Sub-D socket X4 at the back panel of the analyser (specification see 8.2.2): • • • • 4 binary inputs, 4 relay output contacts, 1 common relay alarm contact, and 1 common relay status contact. The binary inputs can be reserved for the following funct– ions (configuration see 12.4.9): • external alarm: an external alarm signal, e.g.
- 32 The following alarm messages are available at the common alarm output: • concentration alarm 1 - 4 (if allocated, see above) Status messages like: • flow alarm, • transducer temperature, • hardware fault, and • fault of the pressure sensor • leaving the current measuring range. are signalised via the alarm LED, the analyser display and the status contact output. Menu point 12.4.6 enables to identify a status fault via a permanent mA-output signal. It is available at the Sub-D socket X3 (see 8.2.1).
- 33 - 17.Maintenance and repair Before carrying out any maintenance or service activities, the engineer concerned must ensure that the analyser is disconnected from the electrical supply of power! • Maintenance of the analyser should be performed by qualified personnel, and the frequency of maintenance may vary as a result of operating experience. • Any used spare parts must be specified as M&C spare parts.
