8 5. Product Description The BLUELYZER is one of the smallest gas analyzer for continuous measurement of flue gases. The instrument measures the values as follows: T.Air Air or ambient temperature in C T.Gas Flue gas temperature in C O 2 Flue oxygen content in Vol.-% Carbon monoxide in ppm Draft Draft or pressure in hpa The values determined are used to calculate and display the following data: Flue gas losses in % 2 Carbon dioxide in Vol.-% u Carbon monoxide, undiluted in ppm Lambda(λ) Excess air value Additional values that can be printed: T.Diff Differential temperature (T.Gas - T.Air) in C Eta Combustion Efficiency in % 3

10 7. General Operating Information 1 Note! In the event of program disturbances please remove batteries! This causes the instrument to return to its initial settings (Reset Function). Attention! In case of repetitive malfunction, replace batteries or connect the instrumentspecific power supply (refer to Technical Data ). Protection of measuring cell In case of overload (-Values exceeding 9999 ppm) the display will alternate between the actual value measured and a warning message " HIGH". Simultaneously, the pump will be switched off! The gas probe must be removed from the flue gas tube immediately! After an initially slow reduction, the concentration at the sensor will fall continuously. The purging of the instrument pump will not start until the excessive gas concentration has fallen below a value of less than 9999 ppm (this is supported by the self-purging function of the instrument). If the display value reaches < 20 ppm, the instrument should be switched OFF and ON again. This initiates a new calibration phase.. Preparing the analyzer for a measurement Sensor connections: Connect the tubings to and from the sensor by means of quick-changes connectors. Connect the temperature plug to the inlet sockets. The connections are colour-coded to prevent any confusion: Yellow = Gas-Temperatur Blue = Air temperature 1 Note! Keep the probe out of the flue during the 60 second calibration phase! 5

11 8. Measurement Principle Temperature measurement: Draft Measurement (Option): K-type Thermocouple (NiCr-Ni) for flue gas temperature K-type Thermocouple (NiCr-Ni) for combustion air temperature Piezo-resistive semiconductor sensor O 2-Measurement: Electrochemical sensor -Measurement: Electrochemical sensor Duration Measurement: Flue Gas Measurement: Max. 60 minutes are possible, followed by a new calibration phase with ambient air. The flue gas is fed to the sensors by means a gas pump via an external water separator and protective filter. Sensor Calibration: Flue gas measurement: Calibration (60 sec) with ambient air. Draft measurement: Calibration (10 sec) to ambient pressure. Flue Gas Sampling: Standard flue gas probe with condensate trap, filter and retainer cone. 6

16 11. System Maintenance & Instrument Care Condensate Trap/Filter: see drawing page 28! 1 Important! Condensate trap or container: Empty completely after each operation. Water in the instrument may have strong or even destructive effects on the pumps and sensors; Damaged or improperly inserted filters will lead to a failure of the filtering function and thus, to a failure of expensive pumps and sensors. Infiltecmicrofilter: Check for contamination and replace if required. NOTE! The microfilter acts as a filter for soot, smoke and dust particles and absorbs water vapor from the condensate contained in the waste gas! In case of strong contamination and/or saturation caused by condensate, the filter must be replaced immediately! After drying and in a clean condition, the filter can be re-used repetitively. Membrane filter (filter disc): Replace in case of decreasing pump flow. Threaded parts must be properly inserted (engaged) and tightened moderately. Proper sealing is ensured by O-rings. U= Batteries must not be disposed of in household waste. Please use proper collection points for disposal. Use specified batteries cells only! Do not mix different types of batteries or new and used cells. Do not charge non- rechargeable batteries. Do not short the terminals!. Keep the instrument dry. 11

26 Functional Description: Draft Measurement during Flue Gas Measurement: O 2 2 T Luft Within the exhaust measurement program the Draft-Measurement can be carried out both continuously and selectively. hpa Continuous (permanent) Draft Measurement Immediately after the calibration phase the pressure sensor is set to zero. If the appropriate presettings have been made, the continuously measured draft and/or pressure value will be indicated in the upper display line. If you wish to hold (lock) the displayed draft value together with all other measurement values press the HOLD key twice. U O 2 2 ppm T Luft Hold-Function hpa 1 Note! The continuous draft measurement is only a measurement that indicates certain tendencies of the pressure pump in operation! Any disturbances, such as pump underpressure, sensor drift, etc., can have a very strong impact on the measuring results. To perform a specified draft measurement the draft must be measured selectively! U ppm 21

27 Selective Draft Measurement O 2 2 T L To precisely determine the draft value a zero-value calibration should be carried out shortly before the draft measurement. Procedure: Preselect Draft Measurement in the upper display line. hpa HOLD Measurement selection (Upper line) Hold measurement values (Pump switches off!) ppm U HOLD-Function Calibrate Draft-Zero-Setting: Remove air tubing before pushing the ENTER-Button! O 2 2 T L hpa Calibration Zero-Setting The pressure sensor will be calibrated.following the zero calibration reconnect the air tube. Wait until the measurement value stabilizes, then HOLD the measured pressure value. HOLD ppm U HOLD-Function 22

28 If a different measurement value is assigned and the HOLD-function is deactivated during a locked Draft-Value in the upper display line, the last measured and locked Draft value will still be maintained! O 2 2 T L C Select Measurement Value (Upper display line) ppm Release measured values (Deactivate HOLD-Function) U After branching back to the draft display, the old draft value re-appears in the upper line of the display. The additional up-arrow indicates that only the pressure value as shown is held. All other measurement values are measured successively and can be shown one by one. O 2 2 T L hpa Repetitive pushing of the HOLD-Button will release the draft-value for new measurements. HOLD ppm Release Draft Measurement Value U 23
