4 Technical DescriptionMeasurement accuracy:Temperature - better than 2KEfficiency / exhaust gas losses - better than 0.2%Electric connections:depending on configuration / componentsMeasurement card:3 42221201926252423Y2 - PT 100measuring elementX2 - no connectIn the 657 R 0896 version, the intake air is specified as a constant. The intake air temperature is not measured. Only recommended where the intake temperatureremains nearly constant over the whole year.You can set the average temperature of the intake air in Parameter 1450.4.5.4 Calculation of CO2 ConcentrationCalculated by referring to the fuel from the measured O 2 value and the CO 2 maximumvalue type 657 R 0910The calculation follows the formula:CO 2 = CO 2 max – (21% -O 2 / 21%)The calculation is based on the following max. CO 2 -contents at = 1 O 2 = 0 Vol.% referenced to dry exhaust gas.Heating oilNatural gas Natural gasELHL15.4 Vol.%12.0 Vol.%11.7 Vol.%Individual specification of CO 2 max. is possible via the parameters 846, 862, 878 and 894.4.5.5 Load-dependent and Fuel-specific Limit Values/Limit CurvesThe burner firing-rate value or some other measured quantity is supplied via analogue input 4or via LAMTEC SYSTEM BUS. Instead of fixed limit values you can enter fuel-specific curveswith 2 up to a maximum of 8 checkpoints.25
