5 2 Application The FIDAMAT 5E is an analyzer for measuring the concentration of total hydrocarbons. It operates according to the principle of flame ionization. The analyzer is suitable for the measurement of all gaseous hydrocarbons. The connection of a heated line is provided in order to prevent condensation and adsorption in the gas supply line. Caution! Explosive gas mixtures must not be measured using the FIDAMAT. The analyzer must not be used in potentially explosive atmospheres. Order No. 7MB MB MB Device type FIDAMAT 5E-P rack-mounted device for process measurements, combustion gas H2 FIDAMAT 5E-AP rack-mounted device for car exhaust measurements, combustion gas H2/He FIDAMAT 5E-G rack-mounted or benchtop devices for measurements of gases of highest-grade purity, combustion gas H2/He 5

6 3 Design The device is available for installation in a 9-inch rack or 9-inch cabinet, the FIDAMAT 5E-G also als benchtop unit. The FIDAMAT comprises two main sections, the analyzer section and the electronics with front panel controls. Analyzer section The analyzer section consists of the oven with detector chamber and various restrictors. The oven is accessible from the side to enable modifications or repairs to be carried out in the installed condition without loosening the electric connections or gas piping connections. The analyzer section also contains pressure regulators, solenoid valves, pressure sensors and a flow sensor. Electronics The electronics consist of the input board which is integrated into the front panel, the motherboard with preamplifier board and the control board. The motherboard contains the EPROMs for the software, the EEPROM for the parameter sets and the switch for the write-protected area on the EEPROM. 6

7 4 Mode of Operation Electrons are released when hydrocarbons are combusted in a hydrogen flame. These electrons are collected at an electrode by means of an electric field and measured using a highly sensitive amplifier. The current is proportional to the quantity of organically-bound C atoms in the sample gas. The sample gas is passed into the measuring chamber via an obstruction-resistant fused silica restrictor. The sample gas is mixed in the measuring chamber with hydrogen or hydrogen/helium (4:6) or hydrogen and a specific amount of air and routed via the nozzle into the combustion chamber. The hydrogen pressure is held constant by a pressure regulator. The balanced system of restrictors and pressure regulators ensures that the sample gas pressure is kept constant. The FIDAMAT operates largely automatically. If the parameters (pressures, temperatures) are set, the device starts up automatically when switched on and ignites when the setpoint temperature has been reached. The hydrogen and combustion air pressures are measured when switching on, and the control panel indicates if they are incorrectly set V DC Flame 2 Quartz nozzle 3 Combustion air 4 Sample gas 5 H2/He or H2 6 Measuring electrode 7 Amplifier Fig. 4 Principle of flame ionization detector (FID) 7

11 6 Installation 6. Mounting The FIDAMAT 5E should be installed or mounted in a vibration-free location. Warning! The device must not be used to measure explosive gases. Operation in potentially explosive atmospheres is not permitted. The permissible ambient temperature (Section 5, Technical Data) must be observed during operation. The FIDAMAT 5E must only be mounted on sliding rails or angled rails. See Section 5 for dimensional drawings. 6.2 Gas Supply Warning! When measuring toxic gases, the exhaust gas must be routed such that there is no danger to the environment. Gases which may lead to explosive mixtures must not be measured using the FIDAMAT. A gas-tight hose or steel piping can be used for the sample gas inlet and outlet depending on the appliction, and must be connected leak-free to the gas connection. The sample gas must be supplied with a pressure of 0 psig (5E-AP) or 5 psig (5E-P, -G), the supply gases with a pressure of 30 psig. The exhaust line from the FIDAMAT 5E must always be routed with a downward gradient since water condenses in it. Mains 20 V X H2 - He comb. air X3 sample gas Fig. 6. Rear panel of FIDAMAT 5E-AP

15 7 Startup, Calibration 7. Startup You should be acquainted with the operation of the FIDAMAT 5! (see Section 8) A prerequisite for correct startup is the presence of hydrogen/helium or hydrogen and combustion air with the appropriate inlet pressure of 30 psig and the sample gas with an inlet pressure of 0 psig (5E-AP) or 5 psig (5E-P, -G). The settling time differs depending on the previous use of the device. It should be 2 to 3 hours for devices which have been used normally. The time is longer for the initial startup or with contaminated devices. The device indicates the current software version when the power supply is connected. Start then appears in the display. The device is in the status Not ready. The hydrogen/helium and sample gas/combustion air pressures are checked immediately at the beginning and when the oven temperatures have been reached. If the device has already been used correctly, the startup is usually carried out without readjustment of the pressure regulators (adjustable screws on front panel). If the message H2" appears in the display, the hydrogen pressure must be adjusted to 000 mbar (980 to 020 mbar) by means of function 35 and using the adjustable screw on the front panel. The device automatically returns to Start" at the end of function 35. If the message Air appears in the display, it must first be made sure, that combustion air (30 psig) and sample gas (0 psig with FID 5E-AP, 5 psig with FID 5E-P and -G) are supplied with the correct pressures. Then the sample gas pressure (combustion air pressure) inside the device must be adjusted to 340 mbar by means of function 36 and using the adjustable screw on the front panel. The device then automatically returns to Start. Once the temperatures have been reached, the device automatically ignites the flame. If there is an appropriate sample gas pressure (0 psig with FID 5E-AP, 5 psig with FID 5E-P and -G) the device automatically switches to the measure mode. If there is no pressure at all or insufficient pressure the device switches to the stand-by mode and waits until there is sufficient sample gas pressure. 7.2 Calibration The calibration should be carried out using gases which represent the gas to be measured as closely as possible. Zero will always be calibrated using function 5, span using function FIDAMAT 5E-G without zero and calibration gas connections, FIDAMAT 5E-AP The calibration is carried out via the sample gas line where the calibration gas pressure must be 8 psig (FID 5E-AP) or 5 psig (FID 5E-G). The setpoint for the sensitivity (function 7) must be entered prior to the calibration. This value can be checked using function 6 - one value must always be entered for function 7. Once the contacts have been closed for longer than sec. the calibration is started and finished after approx. 20 sec. The adjustment by floating contacts is only possible in the meas mode. 5

16 7.2.2 FIDAMAT 5E-P without zero and calibration gas connections The sample gas pressure must be lower than the pressures for zero and calibration gas. During calibration the excess zero and calibration gas flows back through the sample gas line. 6

() LED Autoranging lights up when the corresponding function (20) is active. (2) Dot key with the following meaning: Decimal point Change of sign when entering values Start point of code entries 8.2 Input Example You wish to switch over the measuring range Every input - apart from the codes - must be terminated by ENTER. Press the key in the event of a faulty input. The analyzer is in measurement mode. This means: The green LED lights up for MEAS next to MEAS/CAL. Input:. Since the desired function is in function group, it is not necessary to enter any further codes. Input: press the MEAS/CAL key The green LED lights up next to CAL. The calibration status is thus signalled via pins 24/25 on plug X. Input: The appears in the small display and thus confirms the input. Input: ENTER The measured value disappears in the large display, and a line appears on the right. The green LED lights up in field 6 in front of Switch over measuring range. The green LED simultaneously flashes in front of Range No. in field 8 and thus requests the input of the new range number. Input: 3 Measuring range 3 is selected. The input is output in the large display. Input: ENTER The measured value appears in the large display. The LED 3 lights up in field and indicates that range 3 is active. Input: press the MEAS/CAL key The green LED lights up next to MEAS. If a control panel is present, the status Measure is signalled to it. 8

19 8.3 Coding and Organization of Operating Function Groups The functions are combined into groups according to their type: Function groups Types of function Display functions Calibration and adjustment functions Functions for input of application parameters Functions for input of device parameters To prevent important parameters from being deleted or modified by mistake, there are several function levels which can only be accessed using special codes. Note that the decimal point key must be pressed before entering a code. The factory settings for the codes of the three levels are: Level. Level Level The codes can be redefined using function 50. Function 50 also enables the device protection by codes to be switched off for a certain time or permanently. Code can also be set to zero so that it is omitted. The CAL key must be pressed to signal an intervention on the device to the control room if applicable. The device is automatically recoded by pressing the MEAS key. All operations permissible for a level can be carried out if you are in level, 2 or 3. Higher function levels also include the lower function levels. For example, from function level 3 you can execute all operations of levels 0 to 3, and from level 2 all operations of levels 0 to 2. A description of the operation functions is provided in the appendix. 9

20 8.4 Organization of Data Storage The EPROM and the EEPROM contain three parameter sets: Basic factory-set data User-specific data Current data. All parameters required to operate the FIDAMAT 5E are stored in the EPROM and are protected by hardware (basic factory-set data). These data can be loaded into the current parameter memory using function 53. The user-specific data set is overwritten in the process, however. The basic factory-set data can only be overwritten by a hardware intervention. A second parameter set (user-specific data) is present in an area of the EEPROM which can be overwritten. The user can store a standard parameter set for his application here (see functions 55 and 57). The third data set (current data) is the set which is automatically loaded when the analyzer is switched on. This data set is modified according to the inputs. Note therefore when switching off the analyzer and restarting that it is the current data set which was parameterized when the analyzer was switched off which is loaded and not the user-specific data set.

43 A Display and switch over measuring ranges A * Switch over measuring range Measuring range No. There are four measuring ranges. The measuring range which is switched on is indicated to the right of the display. The number of active measuring ranges can be defined using function 5. The start-of-scale and full-scale values of the measuring range can be freely selected. Factory setting: 2 Display measuring range The start-of-scale and full-scale values of the measuring range are output in succession in the display. 2 Display Measuring range No. ** 20 Autoranging on/off 2 0 Autoranging 0 Manual switchover This function only applies to the recorder output (see plug connector X). The current measured value is always output on the display even if it exceeds the current measuring range. The displayed value flashes when the measuring range(s) is exceeded.

44 B Calibration of measuring ranges B * 5 Calibrate zero (FIDAMAT 5E-AP only) 5 Prior to the activation of this function zero gas must be applied via the sample gas input. 20 s. after activation of function 5 the calibration will be carried out automatically. * 5 Calibrate zero (FIDAMAT 5E-P only) 5 Display Zero gas valve opens after pressing 5 and EN- TER. If there is no such valve, zero gas must be feeded via the sample gas line. After having pressed the ENTER key once more the calibration will be carried out and the zero gas valve (if present) will be closed. 6 Display sensitivity setpoint The setpoint is displayed which was used for the last calibration. The measuring range in which the setpoint is present is output to the right of the display. 6 Display Measuring range No. * 7 Adjust sensitivity setpoint The setpoint must be reset when the calibration gas is changed. All four ranges are calibrated using the same calibration gas. 7 n Identifier Setpoint Identifier: = calibration gas for range (to 4) * 8 Calibrate sensitivity to setpoint The sequence is analogous to function 5. A calibration gas is used to calibrate measuring range. The other measuring ranges are also calibrated. A-2

45 D Temperatures, pressures, flow, limits D ** 34 Display, set max. temperature deviation This function defines how far the oven temperatures may deviate upwards or downwards from the setpoint temperature. A warning is output if the temperature deviates by more than this value for one of the four heaters. 3 4 temperature deviation in C 2 to 0 Factory setting: 5 * 35 Display, set H2/He or H2 pressure 3 5 Display The hydrogen/helium pressure is output on the display in mbar and can be adjusted using the top screw on the front panel. The technical data refer to an overpressure of 000 mbar. * 36 Display, set sample gas pressure 3 6 Display The sample gas pressure is output on the display in mbar and can be adjusted using the bottom screw on the front panel. The technical data refer to an overpressure of 340 mbar (FID 5E-AP) or 500 mbar (FID 5E-P and 5E-G). The pressures will be less if there is no sample gas or combustion air. * 37 Enter tolerance for hydrogen pressure 3 7 Pressure deviation in mbar (0-255) The entered pressure deviation, usually 50 to 00 mbar, specifies the maximum permissible deviation from the setpoint which has been set using function 35. A warning is output if the hydrogen pressure exceeds or falls below this value. Factory setting: 50 * 38 Enter tolerance for sample gas pressure 3 8 Pressure deviation in mbar (0-255) The entered pressure deviation, usually 30 to 00 mbar, specifies the maximum permissible deviation from the setpoint which has been set using function 36. A warning is output if the sample gas pressure exceeds or falls below this value. Factory setting: 30 A-3

46 E Time constants E ** 3 Set time constant T90 The time constant T90 (0. to 00 s) is used to reduce the noise. The signal delay increases with increasing T90. Factory setting: T to 00 seconds ** 4 Set dynamic time constant TD (dynamic noise rejection) 4 Identifier (% of f.s.v.)0.0 to Identifier TD (0.0 to 00 s) The time constant TD applies to small changes in signal without a defined range (in % of respective f.s.v.). The time T90 defined in function 3 applies to larger changes in signal. TD must be larger than T90. In this manner, noise is optimally suppressed in the case of small changes; in the case of larger changes (> ), the modified signal is recorded faster by automatic switching over to the time constant T90. Factory setting: 3.0/.0 F Measured-value memory, current output F ** 2 Measured-value memory on/off 2 On 0 Off If the measured-value memory is switched on, the last measured value is stored when the CAL key is pressed. It is then present at the ma output until the analyzer is reset to the measurement status by pressing the MEAS key. The measured value is also stored in the display in the event of an error.
