ECA 450 IntroductionInstruction 0024-9400 51.4 Operation OverviewThe ECA 450 is microprocessor controlled, allowing it to be easily operatedand configured to suit each operator’s individual needs. Using a system ofmenu selections, the operator is guided through the proper operation and set-up procedures, signaling the appropriate action, and waiting until the correctsteps are taken.The analyzer is powered by either its internal battery pack, or by an ACadapter that operates from any convenient source of 100–240 VAC, 50/60 Hzpower. The analyzer’s control panel consists of a bright and easy-to-read 2¼"× 8" blue vacuum-fluorescent display, sixteen pushbuttons, and one POWERLED. A sampling probe and hose assembly with an integral thermocoupleand water/filter trap provides the means of drawing in gas samples, and formeasuring stack temperature and pressure.A burner’s combustion efficiency is calculated by first entering the fuel beingburned and then allowing the analyzer to measure the burner’s primary airtemperature, stack temperature, and percent Oxygen in the flue gas. Thisinformation is processed by the analyzer, resulting in the display of all themeasured and calculated values that are listed in Section 1.3 Technical Data.For analyzer models that are equipped for environmental monitoring ofcombustion by-products, the gas sample that was drawn into the analyzerthrough its probe is applied to an array of electrochemical gas sensors. Theresults of the analyzer’s gas analyses are shown on the front panel display. |
