1 Introduction Model 5000B Figure 2-3: Interface Panel of the Model 6600 Control Section For safe connections, ensure that no uninsulated wire extends outside of the terminal blocks. Stripped wire ends must insert completely into terminal blocks. No uninsulated wiring should come in contact with fingers, tools or clothing during normal operation. Primary Input Power: The power supply in the Model 6600 will accept a 115 Vac, 50/60 Hz power source. See Figure 2-4 for detailed connections.
Photometric Analyzer Part I: Control Unit Figure 2-4: Primary Input Power Connections 115VAC, Fuse Installation: The fuse holders accept 5 x 20 mm, 4.0 A, T type (slow blow) fuses. Fuses are not installed at the factory. Be sure to install the proper fuse as part of installation (See Fuse Replacement in chapter 4, maintenance.) Analog Outputs: There are eight DC output signal connectors on the ANALOG OUTPUTS terminal block. There are two connectors per output with the polarity noted. See Figure 2-5.
1 Introduction Model 5000B 4–20 mA dc Range ID: 8 mA = Range 1, 12 mA = Range 2, 16 mA = Range 3. Figure 2-5: Analog Output Connections Examples: The analog output signal has a voltage which depends on the sample concentration AND the currently activated analysis range. To relate the signal output to the actual concentration, it is necessary to know what range the instrument is currently on, especially when the analyzer is in the autoranging mode.

Operations/Analysis Unit 4 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 or close proximity zero and span settings, and also to verify that the analyzer response is linear.
4 Operations/Analysis Unit 4.1 Control Functions 4.1.1 Analysis Section, fully explosion proof, Z or X purged Nema enclosure or Cenelec Purged (pending). The control functions for the analysis section are located on the Front of the Enclosure module: 1. POWER ON/OFF: This function is hard wired into the enclosure for power to the control/analysis section. 2.
Operations/Analysis Unit 4 The control unit digital display must handle functions for both the analysis section and the control module. 4.2 Start-p Information contained in this paragraph is based on the premise that the analyzer has been properly installed 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.
4 Operations/Analysis Unit 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. The observations and measurements described in the following paragraphs are vital to the operation of the analyzer.
Operations/Analysis Unit 4 3. If the analyzer section has been equipped with the automatic zero SOL option, the zero solenoid device in the accessory sampling system 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.
4 Operations/Analysis Unit 4.3 Calibration Standardization Fluids Two standardization fluids are necessary to calibrate the analyzer: 1. Zero Fluid: The zero standard fluid must have a composition similar to the sample, and ideally, contains none of the components of interest. The zero fluid should be laboratory analyzed to determine its composition. The exact composition must be known, as the accuracy of the analysis can be no better than the knowledge of the standardization fluid. 2.
Operations/Analysis Unit 4 chemical background has changed. In some cases, TAI is not able to duplicate the background your sample for purposes of optically balancing the analyzer before shipment. In these cases, it is necessary for you to screen for an approximate balance, and to then electronically adjust R3 for precise balance. To do so: 1. Reset R3 to its midpoint. 2. Re-screen the filter wheel, as necessary, to obtain a measuring voltage within 10% of the reference voltage.
4 Operations/Analysis Unit instrument is set up to analyze, then the SPAN control must be adjusted for a full scale reading, i. e., 200 ppm water in EDC. 10. Re-check the ZERO setting with zero fluid. 11. If desired, the linearity of the analyzer can be checked with a fluid intermediate in concentration between the zero and the span fluid. 12. The analyzer is now calibrated.
Operations/Analysis Unit 4 A zero may be established with a reproducible simulated (offset) zero absorbance fluid in the sample cell of the analyzer. When possible this fluid should be stable for H2O content and should approximate the process being measured to minimize the offset zeroing, otherwise, dry air or nitrogen can be used. The analyzer must first be calibrated for sensitivity full scale by using known certified/analyzed samples containing the component (analyte(s) to be measured.
4 Operations/Analysis Unit as the off-line method used to verify the process variables. Below is an example of an on-line calibration when measuring 0-200ppm water in liquid TDI (assumes TDI is a toxic liquid at standard temperature and pressure conditions). The first sample should be taken when the analyte (H20) concentration is known to be low (approximately O-.002 % water).
Operations/Analysis Unit 4 optical filters. These optical filters are stable and are chosen to indicate the measured component at the required instrument wavelengths. Therefore, future, faster, yet much simpler calibration zero and span checks can be made without the unnecessary tedious on-line calibration described above nor the consumption of expensive calibration fluids which may be difficult to handle or obtain, are unstable, or toxic in nature.
4 Operations/Analysis Unit period). In this case, nitrogen or dry air (typically-100OF dewpoint or 2ppm water) can be used. Manually switch in the zero offset check from the control unit to operate the zero solenoid flag (depending upon the application, this may or may not simultaneously insert a zero flag into the light path; indeed, 90% of the time it is not needed).
Operations/Analysis Unit 4 always be corrected using the calibration zero and/or span features. SUMMARY The zero and/or span calibration of 5000 series photometric Teledyne analyzers can be quickly verified manually by using Zero and/or calibration zero offsets and/or span flags.

Operations/Analysis Unit 4 4.4 Operational Theory Cont'd The energy source for the analyzer is most commonly provided by as 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).
4 Operations/Analysis Unit direct meter indication, which greatly eases the task of balancing the system during initial system installation and periods of calibration. The DC voltage levels are fed to a logarithmic ratio amplifier which produces a voltage output that is proportional to the logarithm of the ratio of the two DC input voltages. This output voltage, directly proportional to the concentration of sample, is, within certain limits, a linear function of the concentration.
Operations/Analysis Unit 4 Figure 4-1. Optical System 4.4.2 Sample cell The sample cell, generally constructed of 316SS, is located in the path of the NIR radiation, between the source and the detector modules. Each compound in the sample path exhibits its own characteristic absorption spectrum. Cell spacer thicknesses will vary depending upon the absorbance of the component of interest at the measuring wavelength.

Part II: Maintenance/Analysis Unit Maintenance 5 Maintenance 5.0 Routine Maintenance 5.1 Automatic operation and routine operational duties The system operates continuously without adjustment. Under normal conditions, after you program the system for automatic operation, only routine maintenance procedures are necessary. The most common failure condition is a temporary interruption of the power serving the instrument.

Verify that the recorder has a sufficient supply of chart paper and ink. 5.3 Routine Maintenance Keep the sample lines and components, including the measuring cell within the analyzer sample module, free of deposits and leaks.
Part II: Maintenance/Analysis Unit 5.5 Maintenance 5 Service Procedures and Adjustments 5.5.1 Electronics TAI aligns the system’s electronics. However, you may need to touch up the circuitry, using the following procedure. Equipment Required: Oscilloscope (dual trace is preferred, but not required) To observe oscilloscope test points switch the vertical input selector of the scope to DC. Switch to AC to observe the demodulator switch signals.
5 Maintenance Model 5000B Photometric Analyzer If you open the detector module, keep stray light out by covering the opening with a dense black cloth. If you do not take this precaution, the result is a misinterpretation of the scope patterns. On general-purpose systems, the scope test points are in the bottom of the detector module and are accessible without opening the module. 5.5.
Part II: Maintenance/Analysis Unit Maintenance 5 The procedure is purely mechanical and consists of adjusting the amount of light passing through either the measuring or reference filter, never both. Screens (wire mesh) of varying density are used for this operation and are part of the small took kit accompanying the instrument. 1. Observe the oscilloscope and judge if optical balancing is needed. When the difference is less than 1 volt, balancing is not required.
5 Maintenance Model 5000B Photometric Analyzer 7. After the peaks are balanced, adjust the gain control until the tallest of the two peaks is 8 to 9 volts. The peaks should still be within1 volt of each other. 8. It is always good practice to operate the analyzer with as low a gain as possible. Therefore, with the gain control just barely off its stop, once again remove or add screens in the light path to obtain as high a voltage as possible without exceeding 9 volts for the highest peak.
Part II: Maintenance/Analysis Unit Maintenance 5 5.5.8 Integrated Reference and Measuring Signals You can observe the reference and measuring signal at the first stage of integration by connecting the scope probe to TP6 (reference signal) and TP7 (measuring signal) at the detector unit. A dual trace scope is advantageous but not required for this observation. The test points’ significance is that they reveal proper switch action.
