Typical System Package 1. Instruction Manual IM-103-400A 2. Model 400A Hydrocarbon Analyzer (analyzer configuration dependent on selected options) 3. Power Cord OVERVIEW The following paragraphs provide the equipment descriptions, operating principles, and specifications for the Model 400A Hydrocarbon Analyzer. System Description The Model 400A Hydrocarbon Analyzer automatically and continuously measures the concentration of hydrocarbons in a gas stream. Typical applications include monitoring atmospheric air for low-level hydrocarbon contaminants and determining the hydrocarbon content of exhaust emissions from internal combustion engines. The analyzer provides readout on a front-panel digital display and a selectable output for an accessory recorder. The Model 400A may be equipped with optional features in addition to or in place of the standard equipment features. PRINCIPLES OF OPERATION The Model 400A Hydrocarbon Analyzer uses the flame ionization method of detection. The sensor is a burner in which a regulated flow of sample gas passes through a flame sustained by regulated flows of air and a fuel gas (hydrogen or a hydrogen/diluent mixture). Within the flame, the hydrocarbon components of the sample stream undergo a complex ionization that produces electrons and positive ions. Polarized electrodes collect these ions, causing current to flow through electronic measuring circuitry. Current flow is proportional to the rate at which carbon atoms enter the burner. To ensure stable, drift-free operation, particularly in high-sensitivity applications, an internal temperature controller maintains the analyzer interior at a constant 50°C. This feature minimizes temperature-dependent variations in: a) electronic current-measuring circuitry, and b) adsorption/desorption equilibrium of background hydrocarbons within the internal flow system. 1-2 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A To minimize system response time, an internal sample-bypass feature provides high-velocity sample flow through the analyzer. Burner Operation Principal components of the burner are the manifold, burner jet, and the collector. Streams of sample, fuel and air delivered by the analyzer flow system (described later) are routed through internal passages in the manifold and into the interior of the burner (Figure 1-2). Here the sample and fuel pass through the burner jet and into the flame; the air stream flows around the periphery of the flame. Figure 1-2. Flame Ionization Detection Diagram The burner jet and collector function as electrodes. The jet is connected to the positive terminal of the +90 VDC polarizing voltage. The collector is connected to the signal amplifier. The two polarized electrodes establish an electrostatic field in the vicinity of the flame. The field causes the charged particles formed during combustion to migrate. Electrons go to the burner jet; positive ions go to the collector. Thus a small ionization current flows between the two electrodes. Magnitude of the current depends on the concentration of the carbon atoms in the sample. The burner current serves as the input signal to the electronic measuring circuitry (described later). Mounted on the burner are 1) an igniter, driven by flame ignition circuit and 2) a thermistor sensor for the flame status indicator circuit. 1-3 Instruction Manual Model 400A Response to Different Hydrocarbons IM-103-400A, Rev. 1.0 December 2008 Both speed and magnitude of analyzer response are affected by the type of hydrocarbon in the sample. Typical curves of response versus time for various hydrocarbons are given in Figure 1-3. Magnitude of the analyzer response to an atom of carbon depends on the chemical environment of this atom in the molecule. The characteristic response of a given type of atom may be expressed approximately by a value designated the "effective carbon number." The effective carbon number of a particular type of carbon atom is defined as the ratio between the instrument response caused by an atom of this type and the instrument response caused by an aliphatic carbon atom. Figure 1-3. Downscale Response vs. Time - Typical Curves for Three Samples Table 1-1 lists approximate effective carbon numbers for several types of carbon atoms. Although the instrument does not respond directly to atoms other than carbon, in some compounds certain other atoms do change instrument sensitivity to carbon. For this reason, values are listed for a few non-carbon atoms. Values in the table were determined experimentally, on a single analyzer. Because of slight variations in characteristics of individual analyzers, these values should be regarded as approximations only. To determine the effective carbon number of a molecule of a given organic compound, algebraically add the individual values for the constituent atoms. Examples of effective carbon numbers of molecules are: Butane (C4H1O), 4; octane (C8H18), 8; and ethyl alcohol (C2H5OH), 1.4. 1-4 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Table 1-1.

Its basic function is to deliver regulated flows of sample, fuel, and air to the burner. In addition, the system routes the burner exhaust gas and sample bypass flow out of the analyzer through the corresponding outlet ports. Pressurized gases are supplied to the sample, fuel, and air inlet ports. Each inlet fitting contains an internal filter and flow restrictor. Each of the three gas streams is routed to the burner via a flow control arrangement consisting of the following elements: 1. An adjustable pressure regulator. The air and fuel pressure regulators provide controlled pressure on the downstream side. The sample pressure regulator is a back-pressure regulator that provides controlled pressure on the upstream side. The sample pressure regulator discharges excess sample gas through a bypass port. This bypass feature provides a high velocity sample flow through the analyzer to minimize the system response time. 2. A flow restrictor designed to flow a desired volume of gas. The required flow rate is achieved when the related pressure regulator is properly adjusted. The air and fuel streams use inlet port fittings with sintered metallic flow restrictor elements. The sample stream uses a calibrated capillary tube. 3. A gauge that indicates the pressure at the inlet end of the related flow restrictor or capillary tube. The pressure gauge ranges are: sample pressure gauge, 0 to 5 psig (0 to 35 kPa); air and fuel pressure gauges, 0 to 30 psig (0 to 207 kPa). 1-5 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A Figure 1-4. Schematic Flow Diagram Preamplifier Board The ionization current generated by the burner is measured by an electrometer preamplifier board located adjacent to the burner assembly. This small current is amplified and transformed into a signal voltage that is then further amplified by a post amplifier before being converted to a digital display suitable for direct data presentation. To cover the required dynamic range the amplifier is provided with two gain ranges that differ by a factor of 100. Output voltage from the preamp board is a precise function of ionization current. In equation form: 1-6 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A The most sensitive gain range includes a trim adjustment so that inter-range correlation can be obtained over the entire signal span. A buffer signal offering unity gain and noise filtration provide a low output impedance to drive the signal cable and post amplifier circuits on the main circuit board. Selection of the low or high range feedback resistors (R13 or R14) is made by relay K1 on the preamplifier board. Refer to the preamplifier board diagram, Figure 1-5. A variable offset current is injected into the summing node of the electrometer amplifier to compensate for background offset current. These currents influence the measurement procedure, and a variable voltage at the front panel allows the user to visually cancel these currents during the calibration procedure. Background current is due to unavoidable traces of carbonaceous material introduced into the burner flame by the fuel gas and air. Figure 1-5.

Analyzer Front Panel Display and Controls Digital Displays The voltage originating from the signal amplifiers is made available to output terminals and directly to an analog to digital (A-D) converter for LED data display in digital form. See the PERCENT OF RANGE display in Figure 1-7. The A-D converter is termed 3-1/2 digits, which implies a maximum reading of 1999. The one bit signifying overrange allows 100% excursion above the normal 99.9% range. Thus the user, depending upon span and zero offset conditions, may select the presentation to read directly in percent of full scale and still have 100% overrange capability remaining. A single digit RANGE display indicates the operator selected range (1 through 7) for the hydrocarbon signal voltage. The RANGE indicated is selected by connecting a conductor wire between the SND teminal and the desired RANGE CONTROL terminal on the rear panel of the analyzer. Two LED indicators (REMOTE and FLAME) can light up to indicate 1) that the range selection is being controlled via a REMOTE customer connection, and 2) that the the analyzer FLAME is burning. One or both of the indicators may be lighted when the the analyzer is operating. Span To compensate for various calibration gases, provision is made to vary the gain with a variable span control. The variable span, accessed on the front panel through a calibrated SPAN potentiometer (Figure 1-7), allows gain variation of 400%. 1-10 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A Optically Isolated Remote Range Control To allow for external range control the main electronics board has seven optically isolated digital inputs and one optically isolated digital output. (The digital output is for external range verification.) The external remote range control requires the use of an external (customer supplied) 24 VDC power supply. The range terminals are not suitable for connection to any TTL or equivalent logic circuit sensing. See Section 2, Installation, Electrical Connections. Heater Temperature Assembly The temperature controller is located in the heated compartment of the instrument. The RTD temperature sensor, in conjunction with a control circuit, maintains the internal temperature to meet performance specifications for the instrument. The temperature is controlled at 122°F (50°C). Refer to Figure 1-8. This temperature is maintained at a constant level to minimize temperature dependent variations in amplifier sensitivity and to prevent changes in absorption/desorption equilibrium of trace hydrocarbons in the internal flow system. A blower fan runs continuously to circulate air and equalize the temperature throughout the analyzer. The temperature control board is a multipurpose board with a control resistor that is factory-selected with jumper settings for the applicable analyzer model. The correct jumper settings for the Model 400A temperature control board are made by installing jumper JP3. NOTE 230 VAC operation requires an accessory transformer mounted external to the instrument. If external 230 VAC power is provided, do not change the switch setting on the temperature control board, which is factory-selected for 115 VAC. Selecting the 230 VAC switch setting will cause the case temperature controller to malfunction. Ignition Circuit The ignition circuit is used to light the burner flame during instrument startup. The principle circuit components are as follows: • Igniter element mounted in the burner cap • Step-down transformer (PN 621049) • IGNITE switch mounted on the preamp board and connected in series with the primary of the transformer 1-11 Instruction Manual Model 400A Figure 1-8.

If there is a flammable component in the sample, a fail-safe solenoid accessory is available for wiring in parallel with the fuel solenoid. The flame-out relay board (Figure 1-8) includes the 115 VAC to 24 VDC power converter needed to operate the main electronics board. The flameout relay board provides the 24 VDC power source and relay needed to signal a flameout condition at the customer’s remote monitor station. EQUIPMENT OPTIONS The following optional equipment and features are available for use with the Model 400A Hydrocarbon Analyzer. Refer to the product matrix at the end of this section and the product order number for your analyzer to determine which of the options are included with your unit. Analyzer Mounting Options The standard analyzer is housed in a case designed for bench-top use. If desired, the analyzer may be mounted in a cabinet or rack using RETMA spaced mounting holes. Analyzer mounting dimensions are shown in Section 2, Installation. For safety, the analyzer should be installed in a non-confined, ventilated space. Fuel Gas Options For burner fuel gas, the standard analyzer requires 40% hydrogen/60% nitrogen or helium. Through installation of the optional 400A hydrogen fuel kit (P/N 622576), the analyzer may be converted to use 100% hydrogen. This kit may be ordered as a factory installed option or supplied as an option for installation by the user. 1-13 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A The preferred type of fuel depends on the particular application and the characteristics of the sample gas: • For measuring low-level hydrocarbons in ambient air, or in other sample gas with relatively constant oxygen content, 100% hydrogen is preferable. It provides the highest obtainable sensitivity and the maximum stability. Zero drift caused by ambient temperature variations of the fuel cylinder is somewhat lower for 100% hydrogen than for mixed fuel. (With either fuel, it is desirable to maintain cylinder temperature constant.) • For monitoring vehicular exhaust emissions, or other sample gas with varying oxygen content, mixed fuel is preferable; and a hydrogen/helium mixture is more desirable than a hydrogen/nitrogen mixture. With this type of sample, the use of mixed fuel gas minimizes the error introduced by oxygen synergism. The preferred way to reduce the effect of internal oxygen is to dilute it with an inert gas. This might be accomplished by a constant dilution of sample and calibration gases ahead of the burner but it is simpler and more accurate to provide that diluent in the form of premixed fuel. Both nitrogen and helium have been used as a diluent, but helium has proven to be most effective in improving the equality of response to the various species of hydrocarbons. As indicated earlier the flame output signal is optimum when the ratio of hydrogen flow to inert flow is about 40/60; therefore, this is the chosen composition for hydrogen/helium premixed fuel. The sample flow is kept low to maximize the dilution effect while still providing adequate sensitivity. The burner air flow is normally about four times the fuel flow, and changes have little effect on signal strength. For a given sample flow, the signal can be optimized by adjusting the fuel flow rate. Typical flow rates with premixed fuel are: Fuel Sample Air 100 cc/min. 7 cc/min. 400 cc/min. With a 40/60 premixed fuel, the above flows amount to 40 cc (8%) hydrogen, 67 cc (13%) inert plus sample and 400 cc (79%) air, which compare closely to the 30 cc (8%) hydrogen, 45 cc (12%) inert/sample and 300 cc (80%) air given earlier for straight hydrogen fuel. Since the sample flow in the case of mixed fuel operation is only about one-sixth of that with straight hydrogen fuel, it is clear that higher sensitivity is obtained with straight hydrogen fuel operation. However, in any application where the sample contains more than one species of hydrocarbon and/or a varying concentration of oxygen, the mixed fuel operation should be used. The mixed fuel is recommended, not only for sample containing variable concentrations of oxygen, but for two specific pure gas applications. The first is the case of pure hydrogen samples. The other is the case of pure oxygen samples. If straight oxygen samples are used with straight hydrogen fuel, the mixture entering the burner is essentially 40% H2/60% O2, which tends to produce an unstable signal. The mixed fuel works better. Note that the choice of fuel determines certain analyzer characteristics, as tabulated in Table 1-4. 1-14 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A Table 1-4.

An isolated output of 4 to 20 mA DC (max. load resistance 700 ohms) is obtainable through use of the optional current output board (P/N 6A00302G01) installed during factory assembly or as a subsequent addition. When this board is installed the Model 400A Analyzer provides a selectable buffered output of 0 to 5.0 VDC, 0 to1 VDC, or 0 to 0.1 VDC. Range ID This option provides the user with a remote range identity loop via a dry contact relay output in the ladder logic. See Figure 1-9. This range ID option allows for: 1) remote range control, 2) remote range identification, and 3) terminals for a flameout indication. The range ID option requires a customer-supplied, external, 24 VDC power supply. Figure 1-9. Remote Range ID Logic Diagram Sample Pump Option To provide the required sample flow, the sample gas must be under adequate pressure when applied to the analyzer inlet. To permit analysis of gases at atmospheric or sub-atmospheric pressure, the analyzer may be shipped with a sample pump accessory, P/N 621062. Refer to Section 2, Installation, Fuel and Air Requirements. 1-15 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A Gas Safety Features The Model 400A is designed to provide a high degree of operational safety. In all analyzers, a front-panel LED indicates that the burner flame is lit. In addition, fuel gas is automatically shut off when a flame-out condition occurs. All tubing ahead of the burner is rigid metallic tubing made up with ferrule/nut type compression fittings. However, should there be an internal fuel leak, an inlet fuel flow limiting restrictor, ventilation holes in the enclosure and an internal circulation fan serve to dilute and dissipate the hydrogen fuel for a worst case leak to a safety factor below 25% of the LEL of hydrogen. The design basis for this system presumes 100% hydrogen fuel at 50 psig inlet pressure. 40% hydrogen fuel and lower inlet pressure serve to further reduce hydrogen concentration in the event of a leak. In reality, an open fitting leak would never occur. As a leak developed the burner would eventually be starved of fuel and flame-out would occur at a leak equivalent of a loss of about 20 psig fuel pressure, thus actuating the fuel shut-off solenoid valve . If the sample is flammable, accessory kit P/N 624080, must be utilized. This kit provides a restrictor to limit sample flow and a solenoid valve to shut-off sample in the event of burner flame-out. The design basis for this kit presumes a maximum sample flow rate of 470 cc/min and a sample with LEL not below that of hydrogen (4% v/v in air). Protection against explosion depends on a special fuel flow restrictor in the fuel inlet fitting. Do not remove the restrictor. Replace the fuel inlet fitting only with a factory supplied fitting.

Immediately notify the shipping carrier if the carton or its contents are damaged. Retain the carton and packing materials until the instrument is operational. LOCATION Install analyzer in a clean area, not subject to excessive vibration or extreme temperature variations. Preferably, the analyzer should be mounted near the sample stream to minimize sample-transport time. The analyzer is equipped for rack mounting. Refer to Figure 2-1 for mounting dimensions. For safety and proper performance this instrument must be connected to a properly grounded three-wire source of power. A thermostatically controlled heating circuit holds internal temperature of the analyzer to the correct operating temperature for ambient temperatures in the range 32°F to 110°F (0°C to 43°C). The cylinders of fuel, air, and calibration gas(es) should be located in an area of relatively constant ambient temperature. VOLTAGE REQUIREMENTS This instrument was shipped from the factory configured to operate at 115 VAC, 50/60 Hz. Verify that the power source conforms to the requirements of the individual instrument, as noted on the name-rating plate. Do not operate without doors and covers secure. Servicing requires access to live parts which can cause death or serious injury. Refer servicing to qualified personnel. For safety and proper performance this instrument must be connected to a properly grounded three-wire source of power. NOTE 230 VAC operation requires an accessory transformer mounted external to the instrument. If external 230 VAC power is provided, do not change the switch setting on the Temperature Control Board, which is factory-selected for 115 VAC. A 230 VAC switch setting will cause the case temperature controller to malfunction. 2-2 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A Figure 2-1. Mounting Dimensions FUEL AND AIR REQUIREMENTS During normal operation, the analyzer uses fuel and air to maintain the burner flame. Criteria for selection of these gases are defined in the pargraphs that follow. In addition, the analyzer requires suitable standard gas(es) for calibration. Refer to Section 3: Startup and Operation. For safety and proper performance this instrument must be connected to a properly grounded three-wire source of power. Each gas used should be supplied from a tank or cylinder equipped with a clean, hydrocarbon-free, two-stage regulator. In addition, a shutoff valve is desirable. Install the gas cylinders in an area of relatively constant ambient temperature. Fuel Gas The standard analyzer is equipped to use only mixed fuel, i.e. 40% hydrogen/60% nitrogen or helium. Such blends are supplied by many gas vendors specifically for this use, with a guaranteed maximum total hydrocarbon content of 0.5 ppm, measured as methane (THC < 0.5 ppm). This specification should be used when buying such mixtures. When the analyzer is equipped with the optional hydrogen fuel kit, P/N 622576, 100% hydrogen fuel is to be used. This is also supplied by many gas vendors specifically for this use, with the same guaranteed total hydrocarbon content (THC < 0.5 ppm) which should be specified when buying the gas. 2-3 Instruction Manual Model 400A IM-103-400A, Rev. 1.0 December 2008 NOTE Always make sure the sample flow is present when using the 100% hydrogen fuel option. Absence of sample flow can result in burning of detector tip when using 100% hydrogen. Air Burner air should be relatively free of hydrocarbons in order to ensure a low background signal. Several grades of air are supplied by gas vendors for this use. A maximum total hydrocarbon content of less than 1 ppm is required. (Less than 1 ppm is the THC zero standard). An alternate source of pure air for burner and zero gas can be provided by a diaphragm pump and heated palladium catalyst which effectively removes moderate amounts of both hydrocarbons and carbon monoxide from ambient air on a continuous basis. SAMPLE HANDLING When applying sample pressures greater than 5 psig insure that the bypass regulator is fully open to protect the bypass gauge. Operating range for the internal sample pressure regulator is 4 to 5 psig (28 to 34 kpa) for an analyzer using 100% hydrogen fuel, and 1.5 to 5 psig (10 to 34 kPa) for an analyzer using mixed fuel. With either fuel, sample and calibration gas(es) must be supplied to the sample inlet at a pressure slightly, but not excessively higher than the desired setting on the internal sample pressure regulator. The criterion for correct supply pressure is that the gas flow discharged from the bypass outlet must be between 0.5 and 3.0 liters/minute to operate within the control range of the sample pressure regulator. The flow should be between 2 and 3 liters/minute to minimize system response time. Using excess bypass flow will cause the sample pressure regulator to operate outside its control range and rapid use of the sample and standard gases. If the analyzer is equipped with the accessory 400A sample pump (P/N 621062) the acceptable pressure range at the pump inlet is approximately -1 to +2.5 psig (-7 to 17 kPa). When used, the sample pump automatically provides a sample bypass flow within the correct range. If the sample pump is not used, the bypass flow adjustment is made by a flow controller or a throttle valve in the customer’s sample line, upstream to the sample inlet. Flow may be measured by connecting a flowmeter to the bypass outlet. In the event that flammable sample is to be introduced into the analyzer it must be equipped with accessory kit P/N 624080, which restricts sample flow and provides automatic sample shutoff in the event of burner flameout. DO NOT OPERATE WITHOUT SAMPLE FLOW RESTRICTOR IN PLACE. The sample containment system should also be thoroughly leak checked. This kit is designed considering application on hydrogen sample (LEL=4% v/v). The instrument must not be used on a sample having a LEL less than 4% in air. 2-4 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 GAS CONNECTION Model 400A For external gas lines, the use of all new tubing throughout is strongly recommended. Copper refrigeration tubing is preferred. Stainless steel tubing is less desirable; it contains hydrocarbon contaminants, necessitating thorough cleaning before installation. NOTE In connecting gas supply lines and associated fittings, use Teflon tape only. Do not use pipe thread compound or other substance with an organic base. Do not apply power to analyzer or ignite burner until all leak checks have been performed and until the environment of the analyzer has been determined to be non-hazardous. Refer to leak check procedure presented later in this section of the manual. This analyzer has been designed for use in environments that do not contain combustible or explosive materials. This analyzer uses a fuel containing hydrogen. Leakage from the fuel containment system can result in an explosion. The fuel supply and containment system, both inside and outside the analyzer, should be carefully checked for leaks upon installation, before initial startup, during routine maintenance or any time the integrity of the system is broken. If hazardous sample is to be introduced into this analyzer the leak check procedure should also be applied to the sample containment system, both inside and outside the analyzer. Proceed as follows: 1. Inspect analyzer to make sure that plugs and caps are removed from all inlet and outlet fittings. 2. If a vent line is to be connected to exhaust outlet, use 1/2-inch 10 tube slanted downward at least 10 degrees from horizontal. NOTE Since water vapor is formed during oxidation of hydrogen, burner exhaust gas always contains moisture, even if air and fuel entering the burner are completely dry. Unless exhaust line slants down, water may accumulate in line, causing back pressure and noisy readings. If exhaust line becomes blocked, water may back up in line and flood burner. 3. If sample is toxic or noxious, or is to be reclaimed, connect bypass outlet to suitable disposal system. Do not use any device causing back pressure on burner. 4. Clean external fuel, air, and sample lines and regulators. If necessary, heat lines with torch to drive out contaminants. 2-5 Instruction Manual Model 400A IM-103-400A, Rev. 1.0 December 2008 Do not perform this operation with the fuel, air and sample lines connected to the analyzer. 5. Recommended method is to attach the tubing to either a nitrogen or helium cylinder through a two-stage regulator and adjust the regulator for a low flow of gas through the tubing. Use a propane or natural gas torch to heat the tubing to at least 300°C, working the heat source slowly from the regulator end to the open end. This will remove contaminants from the inside walls of the tubing, and drive them out the open end. 6. Connect external fuel and air lines to fuel and air inlet fittings on analyzer. Connect external sample line to sample inlet on analyzer (or to inlet fitting on sample pump, if used). 7. Adjust regulators on fuel and air cylinders (or other gas supply sources) for appropriate output pressure. maximum permissible pressure at air and fuel inlets of analyzer is 50 psig (345 kPa). The pressure at the air inlet must be at least 5 psig (34 kpa) higher than the desired setting on the air pressure gauge within the analyzer. Thus if the internal fuel pressure regulators are to be set at a typical value of 25 psig (172 kPa), the pressure at the fuel inlet must be set 15 to 20 psi (103,4 to 137,9 kPa) higher than the operating pressure. 8. Supply sample gas at appropriate pressure, as explained in "Sample Handling". Sample bypass flow must be between 0.5 and 3.0 liters/minute for proper operation. Preferably, it should be between 2.0 and 3.0 liters/minute, to minimize system response time. Flow may be measured by connecting a flowmeter to bypass outlet. LEAK CHECK Be particularly careful in checking for leaks in the fuel lines. Fuel gas leakage can cause an explosion. Check all gas connections to ensure that they are leak free. Use of SNOOP (P/N 837801) or other suitable leak-test liquid is recommended. Do not use soap or other organic substances; they will contaminate the system resulting in excessive noise and background current. To leak check the fuel containment system, it is necessary to have full operating pressure within the system. To accomplish this, hold the momentary IGNITE/PURGE switch in the up or PURGE position. 2-6 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A ELECTRICAL CONNECTIONS Before supplying electrical power to analyzer, complete the gas connections and verify that fuel gas connections are leak free. Do not operate without doors and covers secure. Servicing requires access to live parts which can cause death or serious injury. Refer servicing to qualified personnel. Line Power Connection The Model 400A is manufactured to operate only on 115 VAC power. (Note that the power input box and power selection card display only 115 VAC operation.) The power cable supplied is provided with a North American-style parallel blade grounded plug which must be inserted into a 3-wire grounded receptacle. If 230 VAC operation is desired, an external isolated step-down transformer accessory (not supplied) is required. Voltage Output Selection and Cable Connections for Recorder The standard analyzer provides voltage output only. As shipped from the factory, the analyzer is set up for use with a 100 mV recorder (program header jumper JP4). A selection of three voltage output ranges, 0 to 0.1 VDC, 0 to 1.0 VDC or 0 to 5.0 VDC are available at terminals 3 and 4 of the lower six-position barrier strip labeled OUTPUT. Refer to Figure 2-2. To select 0 to 1.0 VDC range, install jumper JP3 on the main electronics board assembly. For the 0 to 5.0 VDC range, install jumper JP2, and for the 0 to 0.1 VDC range, install jumper JP4. This is a fully buffered signal and can be used with most types of voltage recorders. A 10 VDC output displays 1999 on digital readout, indicating 99.9% overrange. A 5 VDC output displays 1000 on digital readout and indicates 100%, the normal instrument span. Fine adjustments to the output voltage can be made with trim potentiometer R64, shown in Figure 2-2.

Refer to Figure 2-3. This current may be transformed back to a voltage using the appropriate resistor. This fully isolated current board is an instrument option and mounts internally on the Model 400A front panel assembly. The maximum value of load resistor is 700 ohms. The 4 to 20 mA is valid over the range of 0 to 100%; the overrange capability of 99.9% is not usable with this option because maximum output of 20 mA corresponds to 5 VDC out. Auxiliary Contacts A Form A contact closure is available on pins CNT1 and CNT2 of the lower barrier strip at the rear of instrument. Refer to Figure 2-3. These contacts may be used with an existing alarm panel or annunciator system, providing the current and voltage limits are observed. The rating for the contacts is 24 V at 1A DC. Contacts operate in parallel with the internal fuel shutoff solenoid and may be used for an external "flameout" indication. Isolated Remote Range Control The analyzer is equipped with an isolated remote range control feature. To use the feature the analyzer requires an external 24 VDC power supply. Figure 2-3. Range ID I/O Board Upper terminals 1 through 7 on the Range ID I/O Board (Figure 2-3) are used for this function. Select RMT on the front panel RANGE MULTI[PLIER switch. Connect the respective line, 1 through 7, to pin 3 (GND) on the lower barrier strip or to pin 9 (24V RET) on the upper barrier strip. The front panel will indicate the range selected. NOTE If no range is selected, the front panel Range LEDs will display a lower case "r". If no external power supply is connected to the analyzer the front panel Range LEDswill display a dash "-". Terminals 1 through 7 correspond to ranges 1 through 7. Table 2-1 shows a simple range selection arrangement. 2-8 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A Table 2-1.

In addition, the REM Range LED on the front panel will light up to indicate that the analyzer is in the REMOTE condition. Remote Range ID The Remote Range ID terminals are also located on the rear panel of the instrument and are shown in Figure 2-3. Range 1 through 7 can be selected by connecting one of the terminals 1 through 7 on the Range ID I/O Board to the 24V RET terminal on the rear panel. Connections are made to bare wire terminals and which are easily removed to facilitate installation. NOTE Range Identity is accomplished by completing a conductive path from the common (C) pin to one of the remote range terminals on the rear panel. Range changes are achieved by applying 24VDC at about 250 mW to the Remote Range ID terminals. Only one range may be selected at a time. Range indication is achieved by individual 24 VDC (1 amp) relay contacts. Range identity relay contacts are limited to 24 VDC. Use of 115 VAC is unsafe. Common control/sense connections may be made to the range control terminals. Voltage and current output signals are also available on the Range ID board. For a current output with less than 600 ohms, the resistor must be placed between terminals +mA and -mA. Voltage output interconnects should be shielded (use the GND output for shield connection) but current output shielding is less critical. If used, current output shielding should be grounded on the reception end (computer or chart recorder). 2-9 Instruction Manual Model 400A IM-103-400A, Rev. 1.0 December 2008 Figure 2-4. Remote Flameout Relay Board Remote Flameout Indication Terminals for flameout indication (Control 1 and 2) are shown in Figure 2-4. Whenever the process flame is detected there is no conductive path between Control 1 and Control 2. When the process flame goes out there is a conductive path between Control 1 and Control 2. The maximum flameout indicator power provided at the control terminals is 24VDC at 1amp. Sample Pump Accessory If a sample pump is used, 115 VAC, 50/60 Hz power must be provided to the pump accessory independently. A power cord is provided with this option and mates with a standard 3-pin power connector at the rear of the housing. 2-10 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Section 3 Model 400A Startup and Operation Initial Startup and Operation . . . . . . . . . . . . . . . . . . . . . . . page 3-1 Routine Operation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . page 3-8 Recommended Calibration Frequency . . . . . . . . . . . . . . . page 3-8 Shutdown . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . page 3-9 Obtaining Maximum Sensitivity . . . . . . . . . . . . . . . . . . . . page 3-9 INITIAL STARTUP AND OPERATION The following paragraphs discuss initial startup, calibration procedures, use of the range switch, and other operating topics for the Model 400A Hydrocarbon Analyzer. Initial Analyzer Startup After installing analyzer per Section 2: Installation, perform the initial analyzer startup and calibration procedure according to the following instructions: 1. Set the RANGE MULTIPLIER switch (located inside the small door on the analyzer front panel) at 1000. Figure 3-1. Range Multiplier Switch http://www.raihome.com Instruction Manual Model 400A IM-103-400A, Rev. 1.0 December 2008 Figure 3-2. Power Switch 2. Locate the rotary latch on the right-hand side of the front panel. Turn the latch screw counterclockwise to unlatch and open the front panel door. 3. Place the power switch (Figure 3-2) to ON. The front panel display should light up. 4. Set external regulators on air and fuel cylinders (or other gas supply sources) for suitable output pressure. Maximum permissible pressure at air and fuel inlets of analyzer is 50 psig (345 kPa). The pressure at the air inlet must be at least 5 psig (25 kPa) higher than the desired setting on the air pressure gauge within the analyzer. The internal fuel pressure regulator is to be set at a typical value of 25 psig (172 kPa), the pressure at the fuel inlet must be set at least 20 Ibs. higher than the operation pressure. 5. If analyzer uses 100% hydrogen fuel, supply actual sample or other suitable gas to sample inlet port of analyzer (or to inlet fitting on sample pump, if provided). Note pressure and flow requirements explained in Section 2: Installation, Fuel and Air Requirements. If analyzer uses 100% hydrogen fuel, an adequate flow of sample or other gas must sample inlet at all times when flame is burning. Otherwise, burner will overheat and damage burner tip. 6. If analyzer uses mixed fuel, sample flow may be initiated at this time, although it is not necessary. 7. Set internal pressure regulators at values appropriate to the fuel gas used. Refer to Table 3-1. 3-2 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Table 3-1. Internal Pressure Regulator Settings Model 400A Internal Pressure Regulator Air Fuel Sample Fuel Gas 100% H2 Fuel psig (kPa) Mixed Fuel psig (kPa) 5 (34) 25 (172) 5 (34) 5 (34) 30 (207) 0 (0) 8. With PURGE/IGNITE switch in PURGE position, wait about one minute for fuel gas to purge flow system. During purging period, rotate fuel pressure regulator alternately clockwise and counterclockwise several times then return to setting specified in step 5. 9. Briefly hold (2 to 4 sec.) PURGE/IGNITE switch in IGNITE position then release. FLAME indicator should now be ON indicating that flame is burning. If so, proceed with following steps. If FLAME indicator does not stay on the flame is not burning. Again actuate IGNITE switch. If flame does not ignite after several attempts refer to troubleshooting chart, Section 4: Troubleshooting. If difficulty is experienced, allowing gas to flow for 20 or 30 seconds in the PURGE position prior to actuating the IGNITE switch may be helpful. NOTE If ignition indication (FLAME ON) is observed without obtaining proper sensitivity, refer to Section 4: Troubleshooting. NOTE When lighting the burner after extended shutdown, the instrument will require time to allow fuel to reach the burner. Extended operation of the switch may be required. 10. Increase setting on internal air pressure regulator to at least 15 psig (103 kPa). Recommended operating settings for internal pressure regulators are air, 15 psig (103 kPa); fuel, 25 psig (172 kPa). Verify that FLAME indicator is still on. The analyzer is equipped with an automatic fuel shutoff solenoid. If flame goes out during subsequent operation, fuel gas flow will shut off automatically. If analyzer has been in regular use, it is now ready for calibration followed by normal operation. However, during initial startup or startup following a prolonged shutdown, the following steps should first be performed. 11. Check for contamination in air and fuel systems: a. Supply a clean, hydrocarbon-free gas, such as pure nitrogen to the sample inlet. Adjust external flow controller or throttle valve so that flow discharged from bypass outlet is between 0.5 and 3.0 liters/minute (preferably between 2.0 and 3.0 liters/minute). Set internal sample pressure regulator at 5.0 psig (34.5 kPa). 3-3 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A b. Set RANGE switch at 10, SPAN control at 1000 (maximum sensitivity), and ZERO control at 1000 (minimum zero suppression). Approximate full scale sensitivity is now 10 ppm as methane for mixed fuels if the analyzer uses 100% hydrogen fuel, and 40 ppm methane if the analyzer uses mixed fuel. c. Check display. Maximum acceptable reading is 50% of full scale. A higher reading indicates that the contamination level is undesirably high. Excessive noise and baseline drift may result, depending on the desired operating range. If the instrument is to be operated at high sensitivity, the source of the contamination must be determined and the condition corrected. The most probable contamination sources are the fuel and air supplies, external regulators and connecting lines, and the internal flow system of the analyzer. If the instrument is to be operated at a sensitivity low enough so that the noise and drift will not be observable on the display or recorder, removal of the source of contamination is unnecessary. 12. With flame burning, allow system to stabilize for at least two hours, and preferably for a day. After initial startup, or after startup following a prolonged shutdown, the analyzer may display baseline drift for a considerable period of time, particularly on the more-sensitive ranges. Commonly, small amounts of hydrocarbons are present on the inner walls of the tubing in both the internal flow system and the external gas-supply system. Drift results from any factor influencing the equilibrium of these absorbed hydrocarbons. Typical causes are change of fuel cylinders or change in temperature or pressure. This type of drift occurs only when the flame is burning. If drift occurs when the flame is extinguished, the electronic circuitry is at fault. To minimize drift, use clean fuel and air, keep the analyzer clean, and locate the gas cylinders in an area of relatively constant ambient temperature. Selection of Calibration Method and Associated Standard Gas(es) Preparatory to normal operation of the analyzer, it is necessary to select a suitable calibration method and appropriate standard gas(es). Proper choice depends on the type of fuel gas, the intended operating range, and the desired accuracy. In all methods, the objective is to establish both a downscale point and an upscale point on the display or recorder chart. Different methods are described in the following paragraphs. Downscale Calibration Point The downscale calibration point is set with the ZERO control, by the appropriate one of two methods: 1. The generally preferred method is to adjust the ZERO control while a zero standard gas of low, accurately-known, hydrocarbon content is entering the sample inlet port. This method is desirable with all analyzers, and is mandatory if the analyzer utilizes 100% hydrogen fuel. Typically, nitrogen (zero gas grade) is used as the zero gas. If desired, the burner air may be used as zero gas, provided that its hydrocarbon content is sufficiently low and accurately known. Although ideally the zero gas should be completely hydrocarbon-free, even the most carefully prepared bottled gas contains trace hydrocarbons. If the analyzer is to be used at high sensitivity, request that the supplier of the zero gas provide an exact determination of its hydrocarbon content. 3-4 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A 2. If the analyzer utilizes mixed fuel, an alternative method eliminates the requirement for a special zero gas. Instead, the ZERO control is adjusted with no gas entering the sample inlet. This method is not possible with analyzer utilizing 100% hydrogen fuel, because the burner would overheat. Even with mixed fuel, the method is not recommended if the analyzer is to be used at sensitivity less than 100 ppm full scale. Refer to Figure 3-3 for typical curves of downscale response versus time for various hydrocarbons. Upscale Calibration Point In all applications, the upscale calibration point is established by adjustment of the SPAN control, while a standard gas of accurately known hydrocarbon content is flowing into the sample inlet port. Since instrument response is linear, it is not necessary that the hydrocarbon content of the span gas fall within the desired operating range. The instrument may be standardized on one range, and then switched to another range without loss of accuracy. Commonly, a conveniently obtained standard such as 100 ppm methane or 1000 ppm methane is used regardless of range. A span gas consists of a specified concentration of methane or other hydrocarbon in a background gas such as nitrogen. Instrument response is affected by the composition of the background gas. Therefore, it is desirable that the span gas contain the same background gas as the actual sample. If so, the background effect is automatically canceled out. Standard Gas(es) Upscale standard gas (and zero standard gas, if used, should be supplied from a tank or cylinder equipped with a clean, hydrocarbon-free, two-stage pressure regulator. Figure 3-3. Typical Curves of Downscale Response vs. Time for Various Hydrocarbons 3-5 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A Calibration Procedure After completing the startup procedure calibrate the analyzer according to the instructions that follow. 1. Set downscale calibration point as follows: a. Supply zero gas to sample inlet. Adjust external flow controller or throttle valve so that flow discharge from bypass outlet is between 0.5 and 3.0 liters/minute (preferably between 2.0 and 3.0 liters/minute). Set th einternal sample pressure regulator at 5 psig. b. Supply span gas to sample inlet. Adjust external flow controller or throttle valve so that flow discharged from bypass outlet is between 0.5 and 3.0 liters/minute (preferably between 2.0 and 3.0 liters/minute). Verify that reading on internal sample pressure gauge is 5 psig or other desired value; if not, adjust sample pressure regulator as required. c. Adjust SPAN control so that the display or recorder gives the desired indication. Lock SPAN control by pushing lever down. Analyzer calibration is now sufficiently accurate for most applications. However, if instrument is to be used for high sensitivity analysis, recheck zero setting (refer to Obtaining Maximum Sensitivity). If recorder readout and display do not agree, correct display by adjusting R1 on front panel board. d. Supply zero gas to sample inlet as in step 1. a. Set RANGE MULTIPLIER switch at 10. Note reading on indicator or recorder; if incorrect, adjust ZERO control as required. Lock ZERO control by pushing lever down. The analyzer is now ready for routine operation. Table 3-2. Range Switch Settings Approximate Operating Range Span Control at 1000 Range Multiplier Setting 1 2.5 10 25 100 250 1000 100% H2 0 to 1 ppm CH4 0 to 2.5 ppm CH4 0 to 10 ppm CH4 0 to 25 ppm CH4 0 to 100 ppm CH4 0 to 250 ppm CH4 0 to 1000 ppm CH4 40/60 Mixed Fuel 0 to 4 ppm CH4 0 to 10 ppm CH4 0 to 40 ppm CH4 0 to 100 ppm CH4 0 to 40 ppm CH4 0 to 1000 ppm CH4 0 to 4000 ppm CH4 NOTE For best results, calibrate with appropriate span gas every time the range is changed. For a clear understanding of the function of the Range Multiplier, refer to the discussion that follows Range Switch (Multiplier) The operator can choose from seven range multipliers as represented by the settings on the range multiplier: 1, 2.5, 10, 25, 100, 250, and 1000. Range 1 is the most sensitive, range 1000 the least sensitive. Range 1 is 10 times more sensitive than Range 10. The range multiplier settings and the display outputs do not represent hydrocarbon concentrations in percent or ppm. The LED display shows the percent of the full scale range which has been calibrated on the multiplier selected. The display also shows which range multiplier has been selected on the range multiplier (1 = 1, 2 = 2.5, 3 = 10, 4 = 25, 5 = 100, etc.). 3-6 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A NOTE If the Range multiplier switch is faulty, the front panel will display and "E". If no range is selected when in the remote range mode the front panel will display a lower case "r". If no external power supply is connected to the analyzer, the front panel will display a dash "-". Range 1 has a maximum sensitivity of 1 ppm CH4 (as 100% full scale) if 100% H2 fuel is used, or 4 ppm CH4 if mixed fuel is used. Range 2.5 has a maximum sensitivity of 2.5 ppm CH4 with 100% H2 and 10.0 ppm CH4 with mixed fuel. Example 1 With the range multiplier switch set at 2.5, the operator can use a 6 ppm CH4 span gas to calibrate the instrument for 20 ppm full scale (30.0% x 20 ppm CH4 = 6.0 ppm). See Figure 3-4 for the display output and range multiplier switch setting. Figure 3-4. Example 1 Display Example 2 After the calibration in example 1, range 10 is now automatically calibrated for 80 ppm CH4 as 100% full scale. (Note that range 10 is 4 times less sensitive than range 2.5). When the operator switches from range 2.5 to range 10, the display (Figure 3-5) will show 7.5% full scale for ppm CH4 calibration gas since 7.5% x 80 ppm CH4 = 6.0 ppm CH4. Figure 3-5. Example 2 Display 3-7 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A Example 3 Likewise, after the calibration in example 1, range 1 is automatically calibrated for 8 ppm as 100% full scale. When switching from range 2.5 to 1 (which is 2.5 times more sensitive than 2.5), the display will show 75.0% full scale for 6.0 ppm CH4 calibration gas (because 75.0% x 8 ppm CH4 = 6 ppm CH4). See Figure 3-6 for the display output and range multiplier switch setting. Figure 3-6. Example 3 Display NOTE The precision of the analyzer is ±1% full scale of range. Analyzer should be calibrated with a span gas that has a hydrocarbon concentration as close to the full scale concentration as possible. ROUTINE OPERATION After calibrating instrument per "Typical Curves of Downscale Response vs. Time for Various Hydrocarbons", proceed as follows: 1. Supply sample gas to sample inlet. Adjust external flow controller or throttle valve so that flow discharged from bypass outlet is between 0.5 and 3.0 liters/minute (preferably between 2.0 and 3.0 liters/minute). 2. Note reading on bypass pressure gauge. It should be the same as that used during adjustment of the SPAN control; if not, adjust sample pressure regulator as required. 3. Turn RANGE MULTIPLIER switch to appropriate position. Indicator (and recorder, if used) will now automatically and continuously indicate the hydrocarbon content of the sample. Normally, the readout is in terms of CH4, since this is the particular hydrocarbon present in the usual span gas. Readings obtained during operation depend on the type, as well as the concentration, of hydrocarbons in the sample. 4. If maximum accuracy and stability are desired, observe the operating requirements explained in "Obtaining Maximum Sensitivity". RECOMMENDED CALIBRATION FREQUENCY 3-8 After initial startup, or startup following a prolonged shutdown, the analyzer requires about one day for stabilization. For the first few days thereafter, calibrate daily. Subsequently the frequency of calibration can be reduced as experience dictates, consistent with the accuracy requirements of the particular application. Instruction Manual IM-103-400A, Rev. 1.0 December 2008 SHUTDOWN Model 400A Use the following procedure to shut down the Model 400A Hydrocarbon Analyzer. For safety in shutdown, always turn off the fuel gas first, then turn off the air and sample lines. 1. Close the fuel gas supply valve. 2. Close the air and sample line valves. OBTAINING MAXIMUM SENSITIVITY If maximum sensitivity is desired, it is necessary to use an optimum combination of settings on the sample, fuel, and air pressure regulators. Settings must be determined experimentally; however, the curves of Figure 3-7, Figure 3-8, and Figure 3-9 may be used as guides. Figure 3-7.

Do not operate without doors and covers secure. Servicing requires access to live parts which can cause death or serious injury. Refer servicing to qualified personnel. For safety and proper performance this instrument must be connected to a properly grounded three-wire source of power. The power plug must be disconnected from the rear of the instrument before removing any of the boards and/or interconnect plugs. SYSTEM CHECKOUT If analyzer performance is unsatisfactory make the following tests in the sequence given. Amplifier Zero Adjustment Place POWER switch at ON; RANGE MULTIPLIER switch at 1000; ZERO and SPAN potentiometers at 1000. With flame extinguished, note reading on front panel indicator, or on potentiometric recorder if used. Reading should be zero; if not, adjust trimming potentiometer R13 on amplifier circuit board. Potentiometer R13 is adjusted by inserting a screwdriver through the lower hole in the amplifier shield. Signal Voltage Trim Adjustment When the voltage output is noticeably higher than the corresponding Percentage of Range display, adjust R64 on the main electronics board until they are equal. Potentiometer R64 can only be used to reduce the output signal voltage. Electrical Leakage Check Turn RANGE MULTIPLIER switch from position 1000 to position 1; indicator or recorder should still read 0 ±5%. If reading is outside this range, leakage is excessive. To determine the source of the leakage, disconnect the amplifier input cable from burner, and note response of indicator or recorder. If abnormal reading persists, leakage is in either the cable or electronics. If reading drops to zero, leakage is in the burner. Clean burner per Section 5: Maintenance and Service. Reconnect cable to burner. http://www.raihome.com Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A Flame Ignition Start up analyzer per Section 3: Startup and Operation, and attempt to ignite flame. If flame will not ignite refer to Table 4-2, Symptom 2. Noise Check With flame burning, observe indicator or recorder. If noise is greater than 2% of full scale, refer to Table 4-2, Symptom 3. Overall Sensitivity Check With flame burning, supply a suitable span gas to sample inlet. Turn RANGE MULTIPLIER switch to a setting appropriate to the hydrocarbon content of the particular span gas. Adjust SPAN control for reading of 100% on indicator or recorder. If the desired upscale reading is unobtainable by adjustment of the SPAN control, the fault may be in either the flow system (Table 4-2, Symptom 4) or in the electronics. Stability Check Supply zero gas to sample inlet. Turn RANGE MULTIPLIER switch to position 1. Observe indicator or recorder over several hours of operation. Drift greater than the stability specification may be due to malfunctioning of the internal temperature control. For comparison Figure 4-1 shows the typical effect of ambient temperature variations on background reading for a standard analyzer, with internal temperature controller functioning normally. In this example, temperature dependent variations in background signal are very small. However, note that such high stability is obtainable only with exceedingly clean cylinder gases. Background signal, and temperature dependent variations in this signal, increase with level of trace hydrocarbon contaminants. If the internal temperature controller is functioning normally, apparent drift may be due to changes in ambient temperature of the fuel and air cylinders. For further information, refer to Section 3: Startup and Operation, "Obtaining Maximum Sensitivity". Figure 4-1. Effect of Analyzer Temperature on Background Signal - Typical Curve 4-2 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A Thermistor The thermistor sensor for the FLAME OUT indicator circuit is mounted in the burner. See Figure 1-2. Thermistor resistance should be approximately 100K ohms at 77°F (25°C). An alternate method requires that the comparator input signal be measured at the junction of R32 and R33. When the flame is burning normally, the voltage at this point will be 0.1 VDC to 0.3 VDC, indicating that the thermistor circuit is functional and the flame temperature is correct. Fuel and Air Restrictors Fuel and air restrictors are porous, sintered metallic, restrictor elements mounted within fittings. If a restrictor becomes plugged, replace it. Do not attempt to clean restrictors with solvents. Sample Capillary The sample capillary is equipped with fittings, permitting convenient removal and replacement. If necessary, the capillary may be cleaned with acetone or methyl. TROUBLESHOOTING Refer to Table 4-1 for LOI fault indications and related probable causes. Refer to Table 4-2 for Symptoms, Probable Causes, and Recommended Corrective Actions applicable to the Model 400A Hydrocarbon Analyzer.

Fuel and/or air filter clogged. Check filters; replace if necessary. Plugged restrictor or capillary Verify that fuel and air restrictors and sample capillary are open. An abnormally low background signal, together with sensitivity loss, indicates plugged restrictor. Note that flame will not light unless fuel and air restrictors are open, but will not light even though sample capillary is completely closed. Electrical elements of burner partially short circuited by combustion products. Clean burner per Section 5, page 5-4. Check valve in sample pump not functioning. Examine check valve. Obstruction in bypass outlet. Examine bypass outlet, remove obstruction. Flame may be lifting above burner tip (unusual condition). With the front panel door open, connect a voltmeter from ground to TP3. If flame is properly lit, the voltage will be below 0.2 VDC. If voltage is high, readjust air-fuel ratio to obtain proper ignition. Re-light burner with richer fuel and air setting. FUEL: 30 psig AIR: 2 to 5 psig.

Check the fuel supply and containment system for leaks, both inside and outside the analyzer, upon installation, before initial startup, during routine maintenance, or any time the integrity of the fuel containment system is broken, to assure that the system is leak-tight. Refer to Leak Check, Section 2, page 2-6. The enclosure is protected by a continuous dilution air purge system, as recommended in IEC* Publication 79-2 (Third Edition - 1983). Do not operate unless the continuous dilution air purge system is properly installed and functioning. Upon startup or loss of pressurization, purge for fifteen minutes before restoring power unless the internal atmosphere is known to be non-explosive. TOPPLING HAZARD This instrument’s internal pullout chassis is equipped with a safety stop latch located on the left side of the chassis. When extracting the chassis, verify that the safety latch is in its proper (counterclockwise) orientation. If access to the rear of the chassis is required, the safety stop may be overridden by lifting the latch; however, further extraction must be done very carefully to ensure the chassis does not fall out of its enclosure. If the instrument is located on top of a table or bench near the edge, and the chassis is extracted, it must be supported to prevent toppling. Failure to observe these precautions could result in personal injury and/or damage to the product. Disconnect and lock out power before working on any electrical components. For safe and proper performance this instrument must be connected to a properly grounded three-wire source of power. This analyzer requires periodic calibration with known zero and standard gases. See Appendix A: Safety Data, "High Pressure Gas Cylinders". 5-2 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A AMPLIFIER ADJUSTMENTS Use the following procedures to adjust the amplifier zero level indication and to trim the analyzer signal voltage if needed. Amplifier Zero Adjustment Place POWER switch at ON; RANGE switch at 1000; ZERO and SPAN potentiometers at 1000. With flame extinguished, note reading on front panel indicator, or on potentiometric recorder if used. Reading should be zero; if not, adjust trim potentiometer R13 on preamp board (Figure 5-1). Insert a screwdriver through the lower hole in the preamp shield to access potentiometer R13. Figure 5-1. Preamp Board Signal Voltage Trim Adjustment Whenever the voltage output is noticeably higher than the corresponding Percentage of Range display,adjust potentiometer R64 on the main electronics board (Figure 5-2). Adjust potentiometer R64 until the voltage output and the Percentage of Range display are the same. Potentiometer R64 can only be used to lower a high signal voltage. Figure 5-2. Main Electronics Board 5-3 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A SERVICING FLOW SYSTEM AND BURNER In preventive maintenance of the flow system, the most important precautions are: 1) provision for continuous removal of all combustion products, including water vapor, and 2) the use of great care to prevent the contamination of any component with hydrocarbons, even in trace amounts. Never touch burner tip, Teflon skirt, or combustion chamber with bare hands; always use clean gloves or cloth. If this precaution is not observed, oil from skin will contaminate these components. Burner Disassembly and Cleaning Disassemble the burner only if contaminants must be removed or if parts must be replaced. Combustion products or other contaminants which accumulate inside the burner may form electrical leakage paths between the collector and the burner contact, resulting in noisy readings. If the instrument is to be operated at the highest sensitivity, traces of such contaminants can cause erroneous readings. For best performance it is necessary that the burner be kept free of any contamination. This analyzer uses a fuel containing hydrogen. Leakage from the fuel containment system can result in an explosion. The fuel supply and containment system, both inside and outside the analyzer, should be carefully checked for leaks upon installation, before initial startup, during routine maintenance or any time the integrity of the system is broken. When burner requires cleaning, proceed as follows: 1. Place POWER switch at OFF position and disconnect power cord. 2. Shut off fuel gas first, then air and sample gases. 3. See Figure 5-3. Unscrew burner cap nut (1) and remove cap assembly (2). 4. On combustion chamber (5), disconnect polarizing voltage cable and amplifier input cable. 5. Lift chimney (3) from combustion chamber (5). Leave exhaust tubing connected to chimney unless chimney is to be replaced. 6. Loosen clamp (6). Lifting straight up, remove combustion chamber (5) from manifold (12). NOTE If burner tip assembly (7) is to be used again, do not touch it with bare hands or any materials likely to contaminate it with hydrocarbons, salt, etc. 7. Unscrew and remove burner tip assembly (7). 5-4 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A NOTE All items used for cleaning (tweezers, swabs, etc.) must be absolutely free of contamination. 8. Clean combustion chamber (5), burner tip assembly (7), and chimney assembly (3) with alcohol followed by a distilled water wash. Figure 5-3. Burner Assembly - Disassembled View 5-5 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A Burner Reassembly Using care not to touch internal parts, reassemble burner according to the following procedure. See Figure 5-3. 1. Holding burner tip assembly (7) with clean tissue, screw the assembly finger-tight into manifold (12). 2. Push combustion chamber (5) down onto manifold (12), taking care not to hit burner tip (7). Tighten clamp (6) on combustion chamber. 3. Install chimney assembly (3) on combustion chamber (5). 4. Install cap assembly (2) and secure with cap nut (1). Hand tighten cap nut. 5. Reconnect all electrical leads. 5-6 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Section 6 Model 400A Replacement Parts PARTS INTEGRITY Tampering or unauthorized substitution of components may adversely affect safety of this product. Use only factory documented components for repair. CIRCUIT BOARD REPLACEMENT POLICY In most situations involving a malfunction of a circuit board, it is more practical to replace the boar than to attempt isolation and replacement of the individual component. The cost of test and replacement will exceed the cost of a rebuilt assembly. Rebuilt boards are available on an exchange basis. Because of the exchange policy covering circuit boards the following list does not include individual components. If circumstances necessitate replacement of an individual component which can be identified by inspection or from the schematic diagrams, obtain the component from a local source of supply. RECOMMENDED SPARE PARTS Table 6-2 provides a list of recommended spares for the Model 400A Analyzer. See Table 6-3 for the relationship between the original parts and the replacement parts.

Antud juhiseid tuleb täpselt järgida, et kindlustada vastavus madalpinge direktiiviga. Euroopa Liitu mittekuuluvad riigid peavad samuti alljärgnevaid juhiseid järgima, va juhul, kui on olemas vastavad kohalikud riiklikud standardid. 1. Ettenähtud maanduspunktide, nii sisemiste kui väliste jaoks tuleb tagada nõuetekohased maaühendused. 2. Pärast paigaldamist või rikketuvastust tuleb kõik turvaümbrised ja turvamaandused uuesti oma kohale seada. Kõigis olukordades tuleb säilitada kõigi maandusklemmide terviklikkus. 3. Toitejuhtmed peavad vastama IEC227 või IEC245 nõuetele. 4. Kogu juhtmestik peab sobima kasutamiseks üle 75°C õhutemperatuuri juures. 5. Kõik juhtmetihendid peavad sisemõõtmete poolest tagama nõuetekohased kaabliühendused. 6. Seadme ohutu töötamise tagamiseks peab ühendus toiteallikaga toimuma vaid läbi automaatkorgi, mis veaolukorras lülitab välja kõik voolukandjad. Automaatkorgil võib olla ka mehhaaniliselt reguleeritav lahklüliti. Vastasel juhul peab seadme toiteallikast lahtiühendamiseks olema teine ja selgelt osutatud moodus. Automaatkorgid või -lülitid peavad vastama tunnustatud standarditele nagu nt IEC947. Kogu juhtmestik peab vastama kohalikele standarditele. 7. Seadmel või ümbristel asuv paremale osutav sümbol tähistab selle all leiduvat ohtlikku pinget. Selliste sümbolitega ümbriseid võib eemaldada vaid juhul, kui seade on toiteallikast lahti ühendatud ning ka siis ainult vastavate oskustega spetsialisti poolt. 8. Seadmele või ümbristele märgitud paremale osutava sümboli all valitseb kuumadest pindadest tulenev oht. Nimetatud sümbolitega ümbriseid võib eemaldada vaid vastavate oskustega spetsialist, kui seade on toiteallikast lahti ühendatud. Teatud pinnad võivad puudutamise jaoks liiga kuumad olla. 9. Seadmel või ümbristel leiduva paremale osutava sümboli korral vt juhiste jaoks Toimimisjuhendit. 10. Kõik selle toote juures kasutatavad graafilised sümbolid lähtuvad ühest või enamast järgmistest standarditest: EN61010-1, IEC417 ja ISO3864. 11. Kui seadmele või siltidele on kirjutatud "Ärge avage voolutarbimine korral" vms, valitseb plahvatusohtlikus keskkonnas süttimise oht. Seadet võib avada ainult siis, kui toide on lahti ühendatud ning seadmel on võimaldatud sildil või kasutusjuhendis osutatud aja jooksul maha jahtuda -- ning ka sellisel juhul ainult vastavate oskustega spetsialisti poolt.

Equipment supplied by Rosemount Analytical Inc. but not manufactured by it will be subject to the same warranty as is extended to Rosemount Analytical by the original manufacturer. At the time of installation it is important that the required services are supplied to the system and that the electronic controller is set up at least to the point where it is controlling the sensor heater. This will ensure, that should there be a delay between installation and full commissioning that the sensor being supplied with ac power and reference air will not be subjected to component deterioration. 3959 12/08 Instruction Manual IM-103-400A, Rev. 1.0 December 2008 Model 400A Model 400A Hydrocarbon Analyzer Part no.____________ Serial no.____________ Order no.____________ Rosemount Analytical and the Rosemount Analytical logotype are registered trademarks of Rosemount Analytical Inc.
