– 1 – 1. OUTLINE The infrared gas analyzer (ZSP) can continuously and accurately measure the concentration of gases such as NOx, SO 2 , CO, CO 2 and O 2 contained in the flue gas from a stationary generating source. The analyzer is available in both single-component and multi-component types depending on customer ’ s specification.
– 2 – 4. INSTALLATION Danger • This product is not explosion-proof. Do not use it in explosive gas-rich atmosphere. Otherwise, serious accidents such as explosion and fire may be caused. Caution • Installation, carrying and relocation must be made by a qualified contractor or your dealer.
– 3 – 4.3 Installation work For installation of the analyzer locker and the extractor, follow the piping instructions in Fig. 4-1 and the separately issued approval drawings (outline diagrams, sampling system diagram).
– 4 – Fig. 4-1 Piping procedure Note 1) To prevent aspiration of leaked air Note 2) Install so that pipe end comes to nearly center of flue and is at right angle to the gas flow. Note 3) Peel off heating pipe by about 2m in order to air-cool measured gas.
– 5 – 5. DESCRIPTION OF EACH PART Please refer to Chapter 14 specification attached at the end of the manual. 6. PREPARATION FOR OPERATION 6.1 Injection of clean water Inject clean water through the filter or air aspiration port until it overflows from the gas conditioner.
– 6 – 6.4 Airtightness test (1) Piping inside panel Since airtightness is confirmed during tests before shipment, an Airtightness test during trial run is usually unnecessary. When a long time has passed after shipment, then carry out the following proce- dure.
– 7 – 7.

– 12 – 8.3 Calibration concentration setting (except zirconia O 2 sensor) Set a span value for the calibration concentration setting. (Zero point calibration concentration is fixed at zero.
– 13 – [When adjusting for each range] (Simultaneous calibration of H and L ranges has been factory-set). Perform setting in the following way. By pressing CAL key while the highest digit of the main indication for the 1st component is flickering, then ‘ ’ will appear on the main indication and ‘ ’ will appear on the sub indication.
– 14 – 8.4 Calibration concentration setting (zirconia O 2 sensor) A zirconia O 2 sensor sets the zero (air) point (span point stipulated in the laws for measurement and weighing) of the O 2 analyzer. For the density of calibration gas to be used, refer to “ 8.
– 15 – ✩ Setting of span calibration concentration (zero point stipulated in the laws for measurement and weigh- ing) Press the CAL key in the status where the digit of the O 2 analyzer main indication is flickering via the zero (air) point calibration concentration setting.
– 16 – 8.5 Zero calibration (air point calibration in case of zirconia O 2 sensor) This is used for adjusting the zero point. Flow the zero gas (0.3 N /min.) by adjusting the needle valve of pressure regulator and wait until the indica- tion stabilizes.
– 17 – 8.6 Span calibration (low concentration point calibration in case of zirconia O 2 sensor) Carry out span calibration by flowing calibration gas at the concentration set as a span value. Flow the calibration gas (0.3 N /min.) by adjusting the needle valve of pressure regulator.
– 18 – 8.7 Auto calibration In this analyzer, the signals form the input/output terminals on the upper can be used for driving an external solenoid valve and introducing standard gas, whereby zero point and span can be calibrated automatically. The auto calibration is done according to 8.
– 19 – Auto calibration abnormality: If an abnormality occurs during auto calibration, a contact signal for auto calibration abnormality will be output from the input/output terminals on the upper of the analyzer. The gas which incurred the abnormality will not be calibrated, and instead the next component will be calibrated.
– 20 – 8.7.1 Current time setting Set the current time and day of the week. Press the FUNC key in the measuring status. The AUTO CAL LED of the function indicating lamps will flicker. The main indication shows the hour and minute via a 24-hour indication and the decimal point flickers.
– 21 – 8.7.2 Auto calibration start time setting When FUNC key is pressed at the current time indica- tion, the auto calibration start time and day will appear on the main and sub indications. The AUTO CALLED of the function indicating lamps will flicker.
– 22 – 8.7.3 Auto calibration cycle setting The calibration cycle is settable in either ‘ days ’ s or ‘ hours ’ . Press the FUNC key at the calibration start time indica- tion and ‘ ’ will appear. The AUTO CAL LED of the function indicating lamps will flicker.
– 23 – 8.7.4 Auto calibration ON/OFF setting Select whether or not to carry out auto calibration. Set to ‘ ’ when calibration will not be made. Note) Press the FUNC key at the calibration gas flow mode indication and ‘ ’ will be appear. The AUTO CAL LED of the function indicating lamps will flicker.
– 24 – 8.7.5 Setting of output hold at calibration This is used when calibrating for holding the output sig- nal at the value just be before entering calibration. (The indication is not held.) The hold function is settable for each component. Press the FUNC key in the measuring status and ‘ ’ will be indicated.
– 25 – 9. OPERATION 9.1 Operating procedure (1) Check if all the preparation for operation have been completed.
