Introduction 1.0 1.0 Introduction The Model 514 Photometric Analyzer measures the concentration of one component in a mixture of liquids or gases continuously by measuring the radiation absorbed in selected bands in the near infrared (NIR) spectral region. Most liquids or gases having a characteristic absorption spectrum in this region can be measured with the analyzer. When we refer to the NIR region we mean that portion of the electromagnetic energy spectrum from 1.0 to 2.8µ.
1.0 Introduction The quantitative measurement of a compound using the 514 is based on Beer’s Law, which states that the intensity of a beam of monochromatic radiation transmitted through a sample decreases exponentially as the concentration of the absorbing sample increases. To approximate monochromatic radiation, a specific wavelength is isolated by the use of the interference-type filters.

Introduction 1.0 1.2.1 Source Module The source module or condulet houses the quartz iodine source lamp, collimating lens/lens holder, and transformer. The 115 VAC power to the source transformer is derived directly from the line voltage regulating transformer installed in the power module. 1.2.2 Sample Module The insulated sample module has sample inlet and outlet lines constructed of 1/8" O.D. 316SS tubing.
1.0 Introduction 1.2.5 Local Meter Readout For analyzer configurations having a remotely located control module, the local meter is used to read the reference and measuring peak heights, or the voltage output from the buffer amplifier before voltage-to-current conversion. When the control module is integral with the analysis section, i. e.
Introduction 1.

Operational Theory 2.0 2.0 Operational Theory The energy source for the analyzer is provided by a high intensity quartz iodine lamp located in the source module. Quartz iodine was chosen because it produces sufficient NIR to operate the system and maintains a nearly constant brightness over its lifetime. (See Figures 2-1 and 2-2).
2.0 Operational Theory At this point the reference signal is fed back to the automatic gain control loop to maintain the desired system gain. In addition, both the measuring and reference levels are fed to selector switches in order to enable direct meter indication, which greatly eases the task of balancing the system during initial system installation and periods of calibration.
Operational Theory 2.0 losses in the sample module due to strong sample absorbance or exceptionally long sample path-lengths. These systems require a focusing lens to gather and collimate the radiation for maximum utilization of source energy. The collimating lens is quartz. Figure 2-1. Optical System 2.1.2 Sample Module The sample cell, generally constructed of 316SS, is located in the path of the NIR radiation, between the source and the detector modules.
2.0 Operational Theory Figure 2-2 2.1.3 Analyzer System - Block Diagram Power Module See Figure 2-3. The power module controls power to the analyzer unit, providing the switching function for the local meter, and providing temperature control for the sample and detector modules. In the case of the explosion-proof configuration, where the control unit is mounted locally, the power module simply routes the AC input power to its destination and allows the control unit to provide the ON/OFF function.
Operational Theory 2.0 From Detector Module NORM/ZERO switch on the power module set to the NORM position, the meter will provide a constant readout of either the reference level or the measuring level. During calibration periods, the ZERO switch control may be used to monitor the signal into the E-to-I converter, and if a known zero sample is applied, then the ZERO potentiometer may be varied to ensure zero output to the control unit.
2.0 Operational Theory ON, the heater is fully turned on; only the duration of the ON interval will vary. As the compartment heats up, the heater-on time interval is shortened. The less heat needed, the shorter the heater-on interval during each cycle. Since TRIAC Q1 is used as the control element for the heater, it is supplied with the full AC line power. The output TRIAC is mounted on a heat sink and can handle the full heater wattage.

2.0 Operational Theory 2.1.4 Detector Module See Figure 2-4. After energy has passed through the sample, it arrives at the filter wheel where it is fed alternately through two filters (measuring and reference) before reaching the detector. These filters are specially selected for each application according to the absorption characteristics of the compounds under analysis.
Operational Theory 2.0 light output and, therefore, the resistance of its shunt resistors. This enables the signal at TP2 to be continually adjusted up or down to hold the reference signal at a constant level (nominally 9 volts) and thus eliminate the effects of turbidity or other foreign substances in the sample, within design limits.
2.0 Operational Theory Power for the detector module is provided by a center-tapped transformer which takes 115 VAC input, reduces it to 40 VAC, then feeds the voltage to the DC power supply. An additional winding on the transformer provides output power to the E-to-I card. The power supply utilizes a fullwave rectifier in order to provide +24 VDC unregulated. The 24 VDC is further filtered, then fed through a voltage regulator to obtain +15 VDC regulated.
Operational Theory 2.0 Power for the control module is provided by a center-tapped transformer which takes the 115 VAC input, reduces it to 40 VAC, and feeds the voltage to a DC power supply identical to the one installed in the detector module. Power supply outputs are +24 VDC unregulated, and +15 VDC regulated.

Installation 3.0 3.0 Installation Before power is supplied to the analyzer, all modules should be opened and inspected for damage or loose components. Also check unit for proper wiring and connections. All plug in circuit cards should be removed and checked individually for correct assembly. 3.1 Location The analysis section should be installed in an area where the ambient temperature does not fall below 32 °F or rise above 110 °F. Steam or electrical enclosure heating may be provided as an option.
3.0 Installation sis. TAI recommends that a bypass filter assembly in the sample loop be installed. Filter installed only when required Bypass Flowmeter Diff. Regulator Sample Flowmeter Ring Manifold Sample Outlet Sample Zero Fluid Analyzer Flow Cell Sample Inlet Span Fluid Regulator Bypass Valve Cell Drain Calibration Fluid Return Sample Return Figuire 3-1. 3.2.
Installation 3.0 The cell with sapphire windows will withstand up to 600 psi pressure. TAI does not recommend high pressure sample handling, but don’t hesitate to slightly pressurize the analyzer for optimum results. 3.2.4 Selector Manifold TAI recommends a three valve selection system that reports into a “ring” manifold for sample and calibration fluid control. Such a system will permit you to conserve calibration fluid. Calibration fluids can be introduced by a simple gravity system.
3.0 Installation WARNING: The light intensity from the quartz iodine lamp is intense and should not be looked at directly without special protective eyewear. Protective goggles with shaded lenses (Fed. Spec. #5) should be worn if it is necessary to look directly at the source. Explosion-Proof Version See dwg. B-16571.

3.0 Installation Signal connections should now be installed from the control unit TS2: -7 (plus), 6 (common) (see dwg. C-15245). 3.5 Optical Alignment The object of optical alignment is to bring the optimum source energy to the detector. Generally the optimum energy will be the maximum amount of energy which can be focused on to the detector. This can be done by adjusting the various elements in the source module (see dwg. C-14628).
Operations 4.0 4.0 Operations Before shipment, TAI calibrates the analyzer for your application when feasible. Calibration data is listed in the Appendix. Prior to calibration, TAI checks the electronics of the analyzer and makes all of the necessary internal printed circuit board adjustments. Calibration is performed to determine the proper zero and span settings, and also to verify that the analyzer response is linear.
4.0 Operations 1. POWER ON/OFF: section. This switch controls power to the analysis 2. NORM/ZERO: NORM setting gives a local meter reading of the peak-to-peak (P-P) voltage of the measuring or reference signal, depending upon the mode setting of the MEAS/REF switch. ZERO setting allows the meter to display the voltage output of the analysis section after comparing the logarithm of the measuring and reference signals.
Operations 4.0 4. ALARM SET (#l and #2): optional controls; position of dial setting determines alarm setpoints. If dual alarms are used, these may be set for high/low, high/high or low/low. Single alarms can be either high or low. Dial settings can be determined from the following formula: X = Unknown dial setting to achieve desired alarm setpoint. A = Analysis scale unit for low end of range. B = Analysis scale unit for high end of range. C = Analysis scale unit desired for alarm setpoint.
4.0 Operations To read output from the control module, the NORM/ZERO, NORM/ REF and NORM/MEAS switches all must be in the NORM position. 4.2 Start-up Information contained in this paragraph is based on the premise that the analyzer has been properly installed as outlined in Chapter 3.0, and that it is in operable condition. If difficulties arise during start-up, it is probable that some form of damage has incurred during shipment or some installation error has inadvertently been made.
Operations 4.0 4. SPAN control preset to the setting noted in Specific Application Data in the Appendix. 4.2.2 Pre-Start-up Electrical Checkout After the preliminary procedures have been accomplished (refer to Preliminary Inspection and Control Settings, above), the integrity of the system interconnection and the power sources must be verified before attempting the analytical start-up procedures.
4.0 Operations should have energized the instant power was established. The device (or devices) should be energized because the mode switch has been preset to the ZERO position. 4. If the test procedure was normal, the devices should have been seen or heard to operate as described by personnel located at the analysis section installation site, and no further check need be made at this time. If operation is not as described, refer to Troubleshooting in Chapter 5.0. 5.
Operations 4.0 control temperature. Make certain that bubbles are not introduced or formed in the cell. (Some back-pressure may help avoid this.) Gas samples can be introduced at about 200 ml/minute. 2. Turn the power module NORM/ZERO switch to NORM. 3. Turn the power module MEAS/REF switch to REF. Verify that the analysis section meter reads 9±0.1 volts. 4. Make adjustment of the measuring peak voltage as follows (zero fluid must be in the sample cell during this adjustment): a.
4.0 Operations balance ring is used, it should be placed over the screen. c. After screening to bring the measuring voltage to within 10% of the reference voltage, adjust R3 as in step a above to make the measuring peak voltage read the same as the reference peak voltage. 5. Turn the NORM/ZERO switch to ZERO. The analysis section meter should be made to read zero by adjusting the coarse ZERO control on the analysis section power module. 6.
Maintenance & Troubleshooting 5.0 5.0 Maintenance & Troubleshooting Under normal operating conditions, little or no maintenance is required. When, after prolonged use, the sample cell builds up an accumulation of dirt or particulate deposits that take the instrument out of range of the ZERO controls, then the sample cell must be removed (see Figure 5-2) and the optics cleaned. The filters should also be checked to see if any deposits have accumulated on their surfaces, requiring cleaning.
5.0 Maintenance & Troubleshooting 5.1 Replacement of Sample Cell Optics If it becomes necessary to remove the sample cell optics for cleaning, proceed as follows (see dwg. C-14631): 1. Loosen the bulkhead nuts on the two Swagelok fittings located on the bottom of the condulet. 2. Remove the four mounting screws that secure the backplate to the condulet interior. 3. Remove the two top mounting screws for sample preheater. 4. Unclip heater assembly from top of the compartment. 5.
Maintenance & Troubleshooting 5.0 4. A total of six spare screens are furnished with the analyzer system. As shown in Figure 5-1, the screens are placed under the filters. Re-screen, as required, then reassemble filter wheel and install by reversing the removal/disassembly procedure. Make sure to reassemble any balance weights or, if balancing facilities are available, re-balance filter wheel if re-screening has resulted in a weight shift. 5. It is extremely important that the filters are not interchanged.
5.0 Maintenance & Troubleshooting 5. Using an oscilloscope, check the AC video signal at TP1 of automatic gain control card (see dwg. B-14564). Maximize the signal output with the adjustment, then tighten all screws in the lens and lamp mounts 6. If an oscilloscope is not available, remove the filter wheel (see Figure 5-1) and place a sheet of white paper in front of the detector. Then adjust the lamp until the brightest, most uniform spot of light is obtained. Avoid dark spots in the middle or sides.
Maintenance & Troubleshooting 5.0 2. Loosen bottom nut on coaxial connector so that connector can be pulled free of the receptacle. 3. Remove mounting screw used to secure subassembly base to detector compartment interior. 4. Release the subassembly box from its mounting flange and carefully remove it from the compartment. The two additional connectors are the slip-on type and can be slipped off of their receptacles as the subassembly is removed. 5.
5.0 Maintenance & Troubleshooting Symptom Cause Corrective Action Calibration voltages near zero on local analysis meter (less than standard 9 VDC). Source lamp burned out. Check lamp and replace, if necessary. After replacement, adjust optics (refer to section ×). Shift in readings at concentration meter. Changes in voltage to source lamp, i.e., changes in line voltage supply to lamp. Check transformer at source lamp module; replace, if necessary.
Maintenance & Troubleshooting 5.0 Symptom Cause Corrective Action Output goes to zero or full scale (either extreme). E-to-I converter defective (check output transistors Q3, Q4 or Q5). Check/replace, if required. If meter sits on zero, also check auto. gain control circuit card; replace, if required. Failure of A1 IC (log amplifier) in log amplifier circuit. Check log amplifier for 0 to 0.4 VDC full scale output. If IC A1 is replaced, make sure that balance potentiometers are adjusted.

Maintenance & Troubleshooting 5.0 given more as an indication of magnitudes to be expected rather than as exact values. The troubleshooting chart cannot possibly identify all malfunctions that may occur. Isolate the malfunction by using the waveform/voltage information, then replace the suspected circuit card. All schematic and and circuit assemblies are given in the Drawing List in the Appendix.
5.0 Maintenance & Troubleshooting Adjustment of R10 and R11 on Chopper-Stabilized Log Amplifier Circuit Card When the log amplifier integrated circuit (A1) is replaced on the chopper-stabilized log amplifier circuit card, it is necessary to readjust potentiometers R10 and R11 in order to balance the circuit. In order to make the necessary adjustments, it is necessary to have an extender card, one 20KΩ resistor, and a high impedance voltmeter. Proceed as follows: 1.
Maintenance & Troubleshooting 5.0 14. The log amplifier integrated circuit (A1) is now balanced. 15. Remove the 20K resistor, the jumper, restore connections, replace ICs, then turn on the instrument power and check control loop by measuring voltage at the output of A2. Voltage should be -3 VDC, nominal. 16. If voltage is positive, R11 is out of balance or a component in the loop has failed.
5.0 Maintenance & Troubleshooting connections should now be installed from the control unit TS2: -7 (plus), 6 (common) (see dwg. C-15245). Power Check 1. Plug in the +15 volt power supply PC card (see dwg. B-14708) but leave all other PC boards out. 2. Turn power ON. 3. With a digital multimeter (DMM), check for +15 volts on the +15 volt power supply. 4. Check for proper starting of the chopper motor and source lamp.
Maintenance & Troubleshooting 5.0 a. Insert an extender card in the switch driver and clamp position. Remove keys as necessary. b. Connect an oscilloscope to pin 6 (video from pre-amp), and pin 3 (ground). c. Remove the lens assembly from the light path. d. Optimize lamp energy by adjusting the lamp position as described in steps 1 and 2 above. e. Replace the lens assembly. f. Focus the lamp as described in step 3 to give the maximum peak heights displayed on the oscilloscope. g.
5.0 Maintenance & Troubleshooting E-to-I Converters Analysis unit E-to-I (see dwg. B-14075): 0-0.5 volts in 10-20 mA out R1 = 50 Ω (TAI P/N R262) Control unit E-to-I (see dwg. B-16631): This is an optional card capable of providing the following outputs with 0-1 volt in and the listed values for R1: 1. 1 to 4 mA, R1 = 250 Ω 2. 4 to 20 mA, R1 = 63.5 Ω 3. 10 to 50 mA, R1 = 25 Ω Alarm Comparator (Optional) See dwg. B-14618. Extended Voltage Amp R3 is installed for outputs greater than 1 VDC (see dwg.
Maintenance & Troubleshooting 5.0 1. Adjust the input square wave at pin 8 to be equal above and below ground. To accomplish this R2 must be raised or lowered in value. This is necessary for proper operation of the rest of the switching circuit. 2. Check the following test points for proper wave forms (refer to Table IV at the end of the chapter): a. TP4 (S). Square wave clamped to ground with +5V P-P. b. TP3 (S). Square wave clamped to ground with +5V P-P 180° out of phase with S. c. TP1 (P).
5.0 Maintenance & Troubleshooting 1. TP1 (Violet): The clamped video should be between -0.4 to – 2V P-P volts. The base line is clamped to ground. Screen the optical beam to achieve -0.4 to -2 volts P-P. 2. At this time set the gain of amplifier A1 to approximately 100. To accomplish this, it is necessary that the peak level detector PCB not be in place due to the fact that it is part of the AGC loop. a. Connect one lead of a dual trace oscilloscope to TP2 (gray), the other to TP3 (green). b.
Maintenance & Troubleshooting 5.0 4. Using a digital multimeter (DMM) at TP4 (orange) adjust P2 on the AGC PCB until 9 volts is obtained. 5. With the meter at TP3 (yellow) adjust R3 of the peak level detector until 9 volts is obtained. 6. Repeat steps 3 and 4 until both TP4 and TP3 read +9.0 VDC. This represents the zero absorbance condition. Log Amplifier PCBs One of three different types of log boards is selected, depending on the application.
5.0 Maintenance & Troubleshooting With the explosion proof units, the power module ZERO, REF, and MEAS levels, and the control unit meter readout for component of interest concentration all are read on the local meter. 1. Set the power module control functions as follows: NORM/REF to REF, NORM/MEAS to NORM and NORM/ZERO to NORM. The REF level is now displayed on the local meter. 2. Adjust the meter trimpot until the meter reads 90% of full scale.
Maintenance & Troubleshooting 5.0 9. Switch NORM/REF to REF. Adjust R36 to give 90% of scale on the analysis section meter. 10. Switch to MEAS. Meter should read 9 VDC. 11. Switch the NORM/ZERO switch to ZERO. Adjust the course ZERO so that the meter reads zero. The ZERO control should end up around 500. 12. The remainder of the adjustments on this PCB must be made in by TAI Photometric personnel. Chopper Stabilized Log Amplifier Refer to dwg. C-14586.
5.0 Maintenance & Troubleshooting 13. Adjust potentiometer R11 until the voltage measured at TP2 is zero. 14. The log amplifier integrated circuit A-1 should now be balanced. 15. Remove the 20K resistor and the jumper. Restore connections, replace IC’s, turn on the instrument power, and check control loop by measuring voltage at the output of A2. Voltage should be -3 VDC, nominal. 16. If voltage is positive, R11 is out of balance or a component in the loop has failed.
Maintenance & Troubleshooting 5.0 2. When the log amplifier integrated circuit A1 is replaced on the chopper stabilized log amplifier circuit card, it is necessary to readjust potentiometers R10 and R11 in order to balance the circuit. You should have on hand an extender card to help make connections accessible, one 20K ohm resistor, and a high impedance voltmeter. a. Temporarily connect a 20K resistor (stable, not composition type) between A1-2 and A1-7, across C2. b. Unplug A2, A3, A5, and A9. c.
5.0 Maintenance & Troubleshooting r. Check pins 8 and 10 on amplifier A3 for presence of +5 volt square wave on scope. s. Switch NORM/REF to REF. Adjust R36 to give 90% of scale (9 VDC) on the analysis section meter. t. Switch to MEAS. Meter should read 9 volts. u. Switch the NORM/ZERO switch to ZERO position. Adjust the coarse ZERO to cause the meter to read zero. The ZERO control should end up around 500. v.
Maintenance & Troubleshooting 5.0 Proportional Heater PCBs See dwg. B-15016. There are three proportional heat PCBs, all of which are located in the power module. 1. There are no adjustments on this card other than the installation of R2 per desired temperature regulation (see section 5.×: Component Selection). The type and value of thermistor used is necessary for proper selection of R2. 2. There are two ways of testing the controlling action of the PCBs. The first is a preliminary test on the board.
5.0 Maintenance & Troubleshooting Extended Voltage Amplifier See dwg. B-16221. To adjust the offset voltage of Q1: 1. Remove the I-to-E converter. 2. With zero volts into pin 2 install a meter at the output of Q1. 3. Adjust R1 for zero offset at the output of Q1. 4. Reinstall the I-to-E board. Meter Trim & Output Voltage Calibration For localized explosion-proof control modules, the trim calibration is done as in the “Meter Trim Circuit Adjustment” section under Log Amplifier PCBs.
Maintenance & Troubleshooting 5.0 2. Change the input voltage to 1 volt. Adjust R12 until the upper current level is achieved. 3. Repeat 1 and 2 until repeatability is achieved. Alarm Comparators, Single and Dual See dwg. B-14718. 1.
5.0 Maintenance & Troubleshooting Photometric Laboratory Calibration Procedure 1. Connect a recorder to the control unit. 2. Remove any screens placed over the sample cell that are in the optical path. 3. Bolt cover on sample compartment. 4. Remove main cover from detector module to gain access to test points. 5. Make certain proper optical filters are in place. 6. Small detector compartment covers must be in place. 7. Turn on analyzer and recorder. 8. With an oscilloscope, check all sync.
Maintenance & Troubleshooting 5.0 to 9.00 volts. When the zero fluid concentration (Cz) is some other value, proceed as follows: Estimate the absorbance change (Afs) expected for full scale changes in concentration. Then from the concentration of the component of interest in the zero fluid (Cz) and the full scale meter reading (Mfs) calculate the voltage setting at TP3 for the zero fluid (Vz).
5.0 Maintenance & Troubleshooting 19. Fill the sample cell with span fluid. Turn unit off, remove chopper stabilized log board and place it on an extender board. Turn the unit back on and adjust R16 on the chopper stabilized log board to give a voltage at TP1 (red) equal to: (Cs - Cz) Vfs Mfs where Vfs is the voltage output from TP1 for full scale deflection, which equals 400 mV.
Maintenance & Troubleshooting 5.0 adjust R16; decrease R17 if you run out of adjustment with R16. The actual limit is 0.5 volts, with 0.4 volts giving some leeway. The log circuit will give accurate results for much higher voltage (as high as 4 volts), but the next stage (E-to-I) will not be accurate above 0.5 volts in. 24. As a check go back to the zero fluid. The meter should read the correct zero fluid concentration. Record the data points as in step 23. 25. Lock zero fluid in the sample cell.
