11 5.2 Switch analyzer on/off and Timer Function After switch on, the analyzer shows on the display for a few seconds, a graphical logo (if installed) or the device name. Then the analyzer behaves differently in grid power or battery power supplied mode Switch analyzer on/off in grid power supplied mode When the user connects mains, the analyzer will switch on itself and start the battery charge function. It is not possible to switch off the analyzer as long as grid power supply stays connected. When grid power supply is disconnected while the battery is charging, the analyzer will switch off itself immediately. Pressing the - key will start the Self Test. Pressing the - key will start the Timer Function (chapter 5.2.2). In grid power supplied mode the Self Test will be left automatically, as soon as all components are OK. Pressing the - key will not switch off the analyzer, but the following window will appear: Select the desired function with Arrows and Enter keys. If there is an optional pressure sensor, this menu also offers to zero this sensor. This window will also be closed without any action by pressing the ESC key. Recharge battery means a restart, which will lead to the battery charge function. Save configuration will store eventually changed user settings in a non volatile memory. 11

12 5.2.2 Timer function The Timer Function allows scheduling a certain time, when the analyzer shall be perfectly ready for measurement, without stressing the measurement components in the meanwhile. In grid power supplied mode the Timer Function is accessed by pressing the function. - key during the battery charge Example: You want to measure in the morning at 8:00 am. In the evening before you install the analyzer at the sample point with connected mains, start the Timer Function and set it to 5:00 am. At 5:00 am the analyzer will leave the Timer window, will start Self Test and will leave the Self Test (when all components are OK) without a press on the ON - key. When you arrive at 8:00 am, the analyzer will already be running since 3 hours, therefore it is perfectly ready for measurement. You will just restart a zeroing when you arrive and after few minutes you can start the measurement with the best possible stability. When grid power supply is disconnected, the analyzer will switch off itself, but it will restart with the same timer settings, when grid power supply returns., : change the timer start in steps of 1 hour : go to Self Test => Zeroing => Measurement, Timer will be deactivated, : go to battery charge window, Timer will be deactivated On Power-ON, the timer is deactivated if is found out that the timer lies more than 1 week in the future or more than 2 days in the past (plausibility check). If the device was started by a timer-auto-start without the ON key was pressed, then press ON-key is faded in all 8 seconds in the middle of the LCD, until the user presses the required key Switch analyzer on/off in battery powered mode (RASI 901) The analyzer will be powered on by pressing the - key. It will go to Self Test. In battery powered mode the Self Test will not be left as long the ON key was not pressed. The analyzer will be powered off by pressing the - key. The following window will appear: Select the desired function with arrows and Enter keys. You can also switch off the analyzer by pressing the ON key again. If there is an optional pressure sensor, this menu also offers to zero this sensor. This window will also be closed without any action by pressing the ESC key. 12

13 5.3 Self test After power on, the displays shows the analyzer type and the analyzer status (actual voltage and temperature values). If one value is provided with an exclamation mark, the set to zero can not be started. One parameter can be ignored if no exclamation mark is being displayed and other measuring conditions are ready (all values are displayed with O.K.) The measurement can be started by means of pressing the key. As soon as ON-key for measurement will be displayed and all measurement conditions are satisfied, the measurement / set to zero can be started by pressing the - key (or automatically) The set to zero process will be started now, indicated by a progress bar in the display s right bottom. After a few minutes Esc will be displayed right of the progress bar, this means now the measurement is possible although the warm-up of the NDIR-bench is not finished. By pressing the Esc key the measurement can be started with reduced accuracy. Esc? With the key the sensors which are not ready for measurement with the best accuracy will be displayed. Set to zero is carried out in the background. For a sufficient accuracy according to analyzers specification, the infrared measuring technology requires a warm up period of at least 30 minutes, dependent on the outside ambient temperature! During this period of time, flue gas measurement cannot be started. Still, all other menu items can be selected. 13

14 After finishing set to zero, the analyzer starts automatically the measurement and the main measuring menu will be displayed. Reset to zero ESC is indicated beside the Reset to zero symbol, as soon as a measurement with diminished exactness of the infrared measuring technology is possible. Set to zero is carried out in the background. For a sufficient accuracy according to analyzers specification, the infrared measuring technology requires a warm up period of at least 30 minutes to get stables values. n the first zeroing after power-on, the analyser starts measurement as soon as the other sensors are ready (after about 10 minutes). Then the analyser starts the measurement, but the NDIR values (e.g. CO2, CH4) are hidden with "---". When 30 minutes are over, the analyser will show in the measurement window's bottom line "NDIR bench ready for zeroing". The user should restart zeroing then to get the measured NDIR values on the display. After finished reset to zero, the analyzer starts automatically the measurement and the main measuring window will be displayed. The multi-page (up to 5 windows) measuring display can be set individually and differently for each of the 4 measuring programs., : change the visible page, : toggle between 4 value indication (zoom) and 10 value indication : store momentary measuring values (assigned to currently selected vehicle) /. : change to menu settings.: change to menu data : change to menu Xtras : change to menu info 14

15 5.4 Operation with gas cooler (RASI ( 901) The built-in gas cooler cools the typical sample gas contains humidity of < 60 C dew point with line voltage supply on 5 C down, with battery operation for energy savings reasons on 10 C under device interior temperature. 5.5 Operation with heating line (RASI 901) A used heating line is heated only at line voltage supply. 5.6 Operation with heating probe (RASI ( 901/RASI 900)) A used heating probe is heated only at line voltage supply. 15

A measuring program contains the following facts for the measuring: 1. the fuel type 2. the CO-threshold 3. configuration of the measuring display 4. configuration of the print-out The device memorizes the fuel assigned with the last measurement and uses this setting again with the next measurement., : change the momentary measuring program (program 1 program 4) The program names are individually editable (Chapter 10.1) 16

17 6.2 Measuring program configuration, : select measuring program, : modify CO cut-off of the selected measuring program modify value in 200 ppm steps : modify the name (Chapter 10.1).: print setting of the selected measurement program : display setting of the selected meas. program : default setting (factory setting) set standard name of the measuring program, : return to setting menu CO-limit The CO-threshold is only available if the analyzer has installed an electrochemical CO sensor. The deposit ppm value determines the CO cut-off. If the measuring value reaches this threshold a second pump for fresh air purging switches on and the CO sensor is switches off by means of a solenoid valve of the gas path. If the ppm value falls short off 20 % of the threshold value the CO sensor will be admitted again with the measuring gas., : modify CO cut-off of the selected measuring program modify value in 200 ppm steps Preset of measurement display For every measuring program it is possible to adjust, which values should be visible in the measuring display. Each measuring program has 5 pages with 10 lines. They can be adjusted individually. During measurement, displays can be paged forward and backward., : select the line (in the first and the last line, the page will be turned), : change measuring value to be displayed at the selected position.: default setting (factory setting) : scroll page downwards : scroll page upwards, : return to setting menu Note: There is no problem in displaying one measuring value on several pages. If e.g. T-gas should be always visible, it can be displayed e.g. on every page. 17

18 Note: If a page only consists of blank lines, it will not be visible while paging. If e.g. only 2 pages are needed, the rest of them should be left blanc Preset for print-out It is possible to adjust for each measurement program, which values should be displayed on the print-out., : select the line (in the first and the last line, the page will be turned), : activate/deactivate print of the selected measuring value : activate/deactivate print of the selected measuring value : activate print of all measuring value : deactivate print of all measuring value (empty print-out), : return to setting menu Measuring values to be printed are marked with *. The list of measuring data can contain more than 40 lines (depending on the existing analyser options) and cannot be shown in one display, not even with basic equipment. 6.3 Preset fuel type, : change the actual fuel type (the analyzer stores the changed fuel type to the activated program. Note: Only the activated fuel types will be displayed (Chapter 6.3)! Activated fuel types are marked with *! 18

20 6.5 Flow measurement (option) This option enables the measurement of the gas flow velocity in the flue gas duct or stack. (option differential pressure is necessary!) The flow measurement is not interrupted. If the measurement display is configured corresponded to the flow measurement (Chapter 6.1) the flow rate [m/s], the flow volume [cfm] and the emission e.g.. CO [mg/s] will be displayed. Requires to measure: Dynamic pressure: measured with the Pitot tube Static pressure: measured with the Pitot tube Flue gas temperature measured with the probe Barometric pressure measured with a barometric pressure transmitter connected at the AUX input or preset the barometric pressure value with the keys Setup flow measurement, : move selection cursor, : change unit velocity unit [m/s] or [feet/s] cross-sectional area Quick input of numbers (Chapter 10.2 Cross-sectional area unit: [cm 2 ], [inch 2 ] or [feet 2 ] Volume flow unit: [l/s], [m 3 /h] or [cfm] Note: The input of the cross-sectional area is only for the volume flow necessary there the analyzer calculates the volume flow by means of the values of velocity and cross-sectional area. 20

21 Connection of Pitot tube for flow velocity measurement Analyzer connection: Pressure Pressure Delta p + Delta P If the measurement display is configured corresponded to the flow measurement the flow rate [m/s], the norm flow volume [cfm] (see Chapter 8.3.7) and the emission e.g. CO [mg/s] will be displayed., : change the visible page, : switch to big display ( Zoom function) : store momentary measuring values /. : change to menu settings.: change to menu data : change to menu Xtras : change to menu info 21

22 6.6 Automatic interval measurement By means of the option automatic interval measurement the analyzer is able to record the continuous measuring values itself. The user may vary the settings of the automatic program according to his needs. Once activated, this option generates measurements and other functions over a longer period of time. These functions can print and/or store the measurements. So the waiting phase is the only phase which is really being changed while changing the interval time. The user cannot change purge time, or zeroing time or gas measurement time. Due to a certain limit of the internal memory, there are also limits in the ratio between the duration of the total measurement and the selectable intervals. The analyzer automatically calculates and limits the total time allowance for the measurements respectively the minimal measuring interval depending on the memory space available. This means a shorter measuring interval will also result in a shorter total measuring time (duration). With an activated automatic print out the measuring interval can of course not be shorter than the printout needs to be completed. Hence the analyzer will not accept intervals shorter than 60 seconds. Please make sure that there is always plenty of paper in the printer when the automatic printout function is activated. Should the printer paper have to be changed during the on-going of an automatic measurement the interval should be long enough to allow the completion of this procedure. The analyzer does not monitor when it runs out of paper. Continuous transmission of the measured values over RS 232 is also ensured during activated automatic measurement. It is therefore easily possible to send data to a computer for storing and evaluation purposes, for example with the software Online View. When a measurement is started the automatic measurement is generally inactive. It has to be deliberately activated by the operator in order to avoid unintended print- and storing. We recommend calibrating the analyzer regularly. During long term measurements the sensors may offset drift a little bit which results in a loss of accuracy. The phase of sensor stability depends on the surrounding conditions and the gas concentration. A rule of thumb is that electrochemical sensors (O2, CO, NO) will not drift before 6 hours and the draft sensor not before 1 2 hours. Make sure that the probe and analyzer filters will not clog during long term measurements. 22

23 6.6.1 Setup of auto-measurement, : change value, auto-measurement on/off, : move cursor, change the line : measuring values : minimum value : maximum value : modify values, Quick input of numbers (chap. 10.2) : end, back to settings Available settings: (Auto-measurement deactivated!) Duration: between 1 and 30 minutes Interval: between 1 und seconds Note: The duration time can never be lower as the interval time! Storage: switch on/off storage in the memory defines whether there is supposed to store measuring data after each interval. Print-out: switch on/off print-out defines whether there is supposed to print measuring data after each interval. Note: The lowest interval time is 30 seconds if print-out is activated. Mean values: calculation of the mean values of the past measuring interval. These mean values will be stored/printed-out instead of the actual values Note: only continuous measurement mode is available with mean values ON! Destinat. memory: selection of where data is going to be stored storage internal or storage on card (optional SD card) When mean values are printed, the printout shows e. g. average value 60s. If there is not enough available memory for the desired auto measurement, the analyzer automatically will shorten the duration and / or extends the interval time. 23

24 6.7 Reset to zero In case readings with ambient air are erroneous (for example negative reading drift), the operator can start manual reset to zero. For reset to zero, the analyzer switches automatically from gas sampling to ambient air sampling and after taking a new zero will switch back to sampling gas. 6.8 Selection of temperature unit, : select the temperature measuring unit between [ C] or [ F] 6.9 Selection of pressure unit, : select the pressure unit Selectable pressure units and the calculation factors: unit number of decimal places calculation factor (with reference to mbar) Pa 1 100,0 hpa 2 1,0 kpa 3 0,1 Mbar 2 1,0 mmh2o 1 10,197 cmh2o 2 1,0197 In.H2O 3 0,4015 mmhg 2 0,7501 In.Hg 3 0,02953 PSI 3 0,

25 6.10 Selection of interval auto-zero, : select the interval duration between two auto-zero cycles (Available settings minimal interval 1/2 hour up to maximal interval 24 hours) It is recommended to set an interval time for auto-zero cycle as small as possible: this will increase the accuracy of analyzer. Low auto-zero interval time will also increase the life time of electrochemical cells! Electrochemical cells require ambient air purge from time to time; the moisture of ambient air will recover the electrolyte from inside the cell. Do not expose electrochemical cells to very high concentration of gas! 25

26 7 Main menu data The analyzer has a storage organisation for measurements minimum. Every measurement has to be allocated a site. It is possible to allocate several measurements to one site. The measurements of one site will be stored directly side by side. If the memory is full occupied the analyzer it is not possible to save more measurements, without delete the whole or a part of the memory. A measurement data block consist: Date and clock time of the measurement Number of the site Measuring values Program and fuel Press key = data: 7.1 Structure of a data block A customer data block consists of: Field name Field size Note Input Site no. 15 definite no. necessary Pos.1 15 Description line 1 e.g. name of site not necessary Pos.2 15 Description line 2 not necessary Pos.3 15 Description line 3 not necessary Pos.4 15 Description line 4 not necessary Pos.5 15 Description line 5 not necessary An unlimited number of measuring data blocks (only limited by the size of the storage) can be saved under one site. When saving the measuring data, the corresponding site has to be selected. Hint: If generally, the customer administration is not used, but data should nevertheless be saved, a customer should be created (Chapter 7.2 ), inserting one blank in the corresponding customer number. In the future, the analyser saves all measuring data blocks without visible customer number and co-ordinates them to the pseudo customer. 7.2 New entry of a site data block Press key F1=new in the display Select a site, the analyser demands the input of the site number. The display Input of Text (see Chapter 10.1) will be opened. Please type the site number. If you cancel the input or do not insert digits, the new customer will not be entered. After input of the site number, the site will be stored in the data base. Now it is possible if requested to fill in the description of the site. 26

27 : new entry (Chapter 10.1) : modify data (Chapter 10.1) : delete data (Chapter 10.1) find data (Chapter 10.1) : end 7.3 Delete all sites All sites and all allocated measurements will be deleted 7.4 Site data from PC Via the RS 232 interface the analyser is able to receive customer numbers including addresses from a PC. For this, the necessary PC software (e.g. Online View) has to be installed. The necessary connection between the measuring analyser and the PC or handheld PC has to be carried out before transmission and shall not to be disconnected during transmission. The included transmission cable has to be connected at the RS 232 interface (COM) of the PC and at the RS 232- interface at the analyzer. Transmission software: 32-bit Data Logger or 32-bit data logger Now the analyser asks, if the already saved sites should be deleted or if the received site should be added to the site database: YES: all saved sites and all measurements will be deleted. NO: no erasing, the new data will be added to the site data. If the site number is not available the existing site will be updated with the new description and the potential measuring data remains allocated. The analyzer receives data from PC. If the transmission connection to PC is ok, the analyzer the started and the analyzer displays: waiting for data Transmission can be interrupted at any time with the If the transmission was in spite of correct connection not successful, the analyzer displays: ATTENTION Transmission was not successful! The data flow was interrupted. The transmission has to be started once again, after restarting the PC transmission program. 27 key

29 7.8 Send measuring data to PC Transmission of the analyzer s internal data memory (not on SD) to PC. Note: To transfer the data of the SD card to PC, you have to pull out the SD card of the RASI card reader and insert this card in the PC card reader. The software OnlineView can open the data files from the SD card in the PC card reader. (For further information see manual OnlineView or Online help of the program) 7.9 Copy measuring data to SD card (option) Copy data memory to SD card Note: Only the SD card # (1 GB) can be used! This card is marked with a sticker on the backside. Other types have no guaranty for usable ness with analyzers! The SD-card option allows the storage of continuous measurements as well as the copying of the data memory onto the SD-card. These dates keep on being able to be processed with the software "Online View" at the personal computer. e.g. option SD card with analyzer RASI

30 Example: Use of the SD card with Analyzer: Insert the card up to the lock. For unloading the SD-card press once again seen on the illustration below. The card will unlock and you may pull it out Format SD card (option) All data on SD card will be deleted. 30

31 8 Main menu Xtras (settings) At delivery, the analyzer has a standard pre-adjusted configuration (factory default), which should cover your needs in the most cases. However, this configuration is highly flexible and individually adjustable. If you would like to modify different configurations, we recommend doing this in a reasonable way. The better the configuration modification is planned, the lesser corrective action must be taken and the easier you are able to work with the analyser. Take advantage of the possibility to individually adjust measurement programs, measuring indications, printings and self-selection fuel in a way, that all of your needs in practice are covered. Then less correction regarding the configurations has to be carried out. The modification is at once useable. The new configuration will be stored after switch off the analyzer (battery operated) or by pressing the - key (power supply operated. Press : in all other main menus for selection of main settings menu 8.1 AUX-channel configuration The AUX channel is an input for recording external signals. These will be sent by a transducer (4 20 ma type or 0 10 V type). This transducer can be supplied direct from the AUX input (12 Vdc, max. 400 ma). If the analyzer is potable or mobile, the connection of a thermocouple type K is allowed. It is possible to edit the name of the transducer, to assign a measuring range and measuring unit. The readed signal will be displayed together with the other values, stored and transmitted to a PC., : selection of the different positions (Input type, name unit, : select AUX input, one of following configurations : default values (factory settings = OFF) : modify the values : store the modified settings, back to the analyser settings 31

35 8.3 Analyzer settings, : select item of analyser to be modified (highlighted item), : modify selected item Set clock Allows operator to set time and date., : modify selected item (hours, minutes, seconds, day, month or year), : move selection cursor Setting display contrast Helping hints The display contrast is depending on the ambient temperature of analyzer (default = 0 % / 20 C). The analyzer compensates the temperature s influence, but there might remain a slight affect. Meaning: Display contrast, 0 % is normal with a temperature of about 20 C. Possible setting: -50 % to + 50 %, (in steps of 5 %) switch ON / OFF Possible settings: ON/OFF There are a couple of messages which are generated automatically by the analyzer and which help an initial user, but which may annoy an experienced user. Examples: 35

36 8.3.4 Country This function allows the change of display language. Following languages are pre-programmed in the firmware of the analyzer: Germany, France, England, Italia, Netherlands, Polska, Russia, USA, Japan, Romania, Turkey, Österreich, Belgium, Ceska,.: change country/language ATTENTION! A change of language/country also changes the list of fuel types and there parameters. As losses and efficiency are calculated with fuel parameters, previously stored measurements will be recalculated most probably with other parameters and will therefore result in other/wrong values. In this case you should change the language/country back in order to see correct storage contents Negative gas readings Select T-gas sensor type Switch on / off the negative gas readings with, keys. If the analyzer is operating for long time without a new reset to zero, the measuring values could drift from zero in both directions, negative and positive. HINT: If this function is switched on, it is a good chance, to see that the analyzer requires a new reset to zero! To see negative drift on the display, set Negative gas readings ON To hide negative drift on the display, set Negative gas readings OFF Available settings between thermocouple type K and type S selectable with, keys. T gas sensor type K: NiCrNi thermocouple T-gas-sensor type S: PtRhPt thermocouple Thermocouple type S is necessary for probes with temperature range up to C Reference temperature, : select 0 C, 15 C or 25 C In different countries, there are different local regulatory of standard gas condition. For example in Europe the norm cubic meter of gas is determined at 0 C, other countries require higher temperature for norm cubic meter (or feet)! This setting has influence on the calculation of gas concentrations in mg/m3, e.g. CO [mg/m3] and the norm flow volume [cfm]. Standard setting: 0 C, other settings: 15 C or 25 C Hold delay after purge, : select min. 0 sec. to max. 225 sec in 15 sec. steps In case of automatic reset to zero (or back purge of probe for stationary analyzers), it is possible to hold the last value of analog outputs 4 20 ma and in the measurement menu previous to these functions (see analog output configuration Chapter 8.6?) In addition to hold time during auto-zero (back 36 purge), analyzer can hold these values with a user selectable delay time up to max. 255 seconds.

37 8.4 Service values If an analyser malfunction should occur (e. g. message during calibration: " O 2 sensor not OK"), the malfunction can mostly be localized in the Service menu. The analogous values (= not calculated rough values) of all sensors will be displayed. Please contact our after-sales service in case of an error (see address / phone number on page 3). In order to localize the defective part, our technicians may ask you same service values or ask Eurotron Instruments (UK) ltd., : page turning, : move lines (in the first and the last line, the list will be moved = scroll) : switch between service values analog and infrared module.: tests: only for service department : trends.: only for service department : Internal heating: only for service department : back to the menu Xtras 37

38 8.5 Adjustment The adjustment menu is protected against use of non-authorized persons by a PIN code. For PIN code ask the service department. At wrong input of PIN code, the analyser will return to main settings menu Main adjustment menu Note: The adjustments temperature, pressure, AUX and analog output are factory made, it is generally not necessary to repeat them! Before starting the adjustment of gas measurement, it is advised to carry out a zeroing of this measurement. Connect analyser s inlet port to the gas calibration facility as in the picture below. Observe the flow of bypass calibration gas in the flow meter (4) and adjust regulator (2) for some 3 7 l/h. Cal gas will be sucked by the gas pump and has no pressure! A small excess of cal gas will be vent by the flow meter, insuring that no false air will be sucked by the gas pump. Pressurizing the electrochemical sensors will be damage them! 1 test gas cylinder 2 pressure reducer 3 T-connector 4 Flow-meter 5 Calibration gas inlet of analyser 38

43 8.6 Setup analog output (4 20 ma) Setup analog output allows configuring all 8 analog output channels 4 20 ma. To each of the analog output channels you can assign a measuring value and a measuring range., : move selection cursor, : print-out the current analog-output configuration (for usage at another place),, : change the setting selected by the cursor,, : back to the Xtras menu The example illustration shows the following setting: O2 [%] Channel 1 [ma] Setup analog output During zeroing This setting determines the analog output s behavior during zeroing: hold: The outputs will keep the last measured value before the zeroing. 2mA: The outputs will change to 2mA in order to indicate the zeroing state. This setting is common for all analog outputs; they will behave in the same way Setup analog output Output Channel Select the channel 1 through 8, which you want to configure. Below this line you can check or change this channel s assigned measuring value and range (min and max) Setup analog output Measuring value Here you can assign a measuring value to the selected Output Channel. All values are assignable, directly measured values e.g. CO [ppm] as well as calculated values e.g. Exc.Air Setup analog output Minimal value (lower range end, correspond to 4 ma) This setting determines the lower output range s end value, which corresponds to 4mA. If the assigned measuring value falls below this end value, the output will stay on 4mA Setup analog output Maximal value (upper range end, correspond to 20 ma) This setting determines the upper output range s end value, which corresponds to 20mA. If the assigned measuring value exceeds this end value, the output will stay on 20mA. 43
