Page 4: Safety Instructions
METROTEC Safety instructions Please read through this operating manual very carefully before in- & stalling and commissioning the unit. Incorrect utilisation will invalidate the guarantee! Correct functioning and the operating safety of the unit can only be guaranteed if the ambient conditions specified in the Specifications chapter are maintained. -
Page 5: Preface
METROTEC Preface With the aid of an oxygen sensor , the measurement unit serves to measure the oxygen partial pressure in gaseous atmospheres. Such sensors work at high temperatures and so it is neces- sary for measures to be taken to ensure that no flammable gas mixtures contact the sensor or the unit. -
Page 6: Introduction
METROTEC Introduction Measurement principle Oxygen measurement units are designed to process signals transmitted from an ox- ygen sensor constructed of stabilized zirconium oxide. Zirconium oxide, a ceramic material that is also spoken of as a solid-state electrolyte, acts as an excellent oxy- gen-ion conductor when at a high temperature. -
Page 7: Measurement Electronics
METROTEC Measurement electronics The electronic circuit of the measurement unit Type GSM provides the following functions: Measurement of the oxygen partial pressure Maintaining the oxygen content at a preset level Generating alarm signals Option: Calculation of the dew point Option: Calculation of the air factor lambda point The device is operated with the aid of a keypad. -
Page 8: Description Of The Measurement Electronics
METROTEC Description of the measurement electronics The elements at the front of the unit are in three groups Keypad: The keypad has four keys by means of which all the necessary functions can be effected. Display: The graphic display provides for the display of measured values, data, time graphs and mes- sages. - Page 9 METROTEC When the gas inlet is opened and the gas pump is switched on, the unit should indicate 20.9 % O If necessary, a correction can be made as detailed under "Correction" in the oper- ating instructions. The gas who's properties are to be measured is then fed to the sensor. The rate of flow should...

Page 11: Putting The Unit Into Operation
METROTEC Putting the unit into operation Switching the unit on Once all electrical connections have been made and checked, the power plug is plugged in. After waiting for about 15 minutes for the sensor to be heated up, the unit indicates the oxy- gen content of the gas concerned. -
Page 12: Location Of Condensate
METROTEC 5.4.4 Location of condensate collectors When fitting a condensate collection vessel, especially one for water, it should be ensured that it is located at the lowest point in the entire piping system.. It should be borne in mind that the filling of empty space in condensate collectors and filters will result in some delay in effecting measurements 5.4.5 Filter system arrangement:... -
Page 13: Operation
METROTEC Operation A few seconds after switching on, the first page is displayed as follows: Each page has a headline that is separated by a line from the rest of the display. This headline indicates the page number and the title or an outstanding fault message. Beneath the line there is either a graph or a 6-line text. - Page 14 METROTEC Þ The two arrow keys provide for moving the cursor line upwards or downwards or for in- creasing or decreasing values when alterations to entry fields are enabled. Þ The key on the right provides for a) Opening a display page b) Opening an entry field to enable an entry to be made c) Closing an entry field and storing an entry.

Page 17: Configuration
METROTEC Configuration Enablement of Configuration Before parameters can be altered it is first necessary to overcome the disablement code. Only then is access to additional pages possible. Enablement is effected as follows: 1. Select the page entitled CODE in the page selection table. -
Page 18: Displayed Values
METROTEC You then have access to the page selection list once more. Note: Access to parameters and configurations is enabled for only a limited period. (90 seconds) If more time is needed, then it will be necessary to repeat the steps needed t overcome the disa- blement code. -
Page 19: Process Parameters
METROTEC Here you can adjust the measured value with an set point value of a test gas by varying “EMF+” or “EMF*”. The result is displayed under “LOG” and “O2” The value 0.00 for the additive correction and of 1.0 for the multiplicative correction means that no correction is to be applied to the determined EMF value. - Page 20 METROTEC lambda: values for outputs 1 and 2 are thus displayed on one page and those for Output 3 on a separate page.

Page 21: Alarm Output
METROTEC Alarm output The definition of Alarm is self evident. It has also to be defined whether the physical output is to be a relay or a semiconductor. Control output It has also to e defined whether the physical control output is to be a relay or a semiconductor. -
Page 22: Scaling Of The Trend Graphs
METROTEC Scaling of the trend graphs The scaling of the graphs cannot be altered. Alterations to the axes can only be effected by the supplier. Exception: The Y-axis will be enlarged 4 times if „+“will be pressed. Pressing „-„ the origi- nal scale is active again. -
Page 23: Lambda
METROTEC Lambda For some applications it is of importance to know the lambda value of a combustion gas or of a gas/air mixture. In this case, lambda is defined as follows: Lambda = (combustion air supplied)/( combustion air theoretically required) If this feature is required, it is necessary for a characteristic value to be entered in the "Param-... -
Page 24: Interfaces
METROTEC Interfaces Analog interfaces The device has three 0 – 20 mA analogue interfaces all of which can be active at the same time. A change to 4 – 20 mA can be effected by the user. Digital interfaces 9.2.1 Standard interfaces There are two relays, either of which can be defined as either a control output or as an alarm output. -

METROTEC 10.2 Filter factor If there is excessive fluctuation in the measured values, it is possible to apply an attenuation factor of between 0 and 200. This attenuation factor has an integration effect on the oxygen value. The necessary entry is detailed under "Configuration Process parameters". -
