Per cent Oxyg en Anal yz er ercent Oxygen Analyz yzer Operational Theory 2 Operational Theory 2.1 Introduction The analyzer is composed of three subsystems: 1. Micro-Fuel Cell Sensor 2. Sample System 3. Electronic Signal Processing, Display and Control The sample system is designed to accept the sample gas and transport it through the analyzer without contaminating or altering the sample prior to analysis.
2 Operational Theory Model 3000PA analyzed. The Micro-Fuel Cell is therefore a hybrid between a battery and a true fuel cell. (All of the reactants are stored externally in a true fuel cell.) 2.2.2 Anatomy of a Micro-Fuel Cell The Micro-Fuel Cell is a cylinder only 1¼ inches in diameter and 1 inch thick. It is made of extremely inert plastic, which can be placed confidently in practically any environment or sample stream. It is effectively sealed, although one end is permeable to oxygen in the sample gas.
Per cent Oxyg en Anal yz er ercent Oxygen Analyz yzer Operational Theory 2 the oxygen sensing element—the cathode—with a surface area almost 4 cm2. The cathode has many perforations to ensure sufficient wetting of the upper surface with electrolyte, and it is plated with an inert metal. The anode structure is below the cathode. It is made of lead and has a proprietary design which is meant to maximize the amount of metal available for chemical reaction.
2 Operational Theory Model 3000PA (These reactions will hold as long as no gaseous components capable of oxidizing lead—such as iodine, bromine, chlorine and fluorine—are present in the sample.) The output of the fuel cell is limited by (1) the amount of oxygen in the cell at the time and (2) the amount of stored anode material. In the absence of oxygen, no current is generated. 2.2.

A few typical Micro-Fuel Cells are listed below with their typical use and electrical specifications. 2.2.6.
2 Operational Theory Model 3000PA Nominal output in air is 0.19 mA, and 90 % response time is 45 s. Expected life in flue gas is 8 months. 2.2.6.3 Class B-1 Cell The class B-1 cell is for use in applications where it is exposed to less than 0.1 % of carbon dioxide, and where fast response is important. Nominal output in air is 0.50 mA, and 90 % response time is 7 s. Expected life in air is 8 months. 2.2.6.

The sample system for the standard instrument incorporates ¼ inch tube fittings for sample inlet and outlet connections at the rear panel. For metric system installations, 6 mm adapters are supplied with each instrument. The sample or calibration gas flow through the system is monitored by a flowmeter downstream from the cell.

Per cent Oxyg en Anal yz er ercent Oxygen Analyz yzer Operational Theory 2 The signal processing electronics including the microprocessor, analog to digital, and digital to analog converters are located on the motherboard at the bottom of the case. The preamplifier board is mounted on top of the motherboard as shown in the figure. These boards are accessible after removing the back panel. Figure 2-7 is a block diagram of the Analyzer electronics.
2 Operational Theory Model 3000PA In the presence of oxygen the cell generates a current. A current to voltage amplifier converts this current to a voltage, and then the voltage is amplified in the second stage amplifier. The second stage amplifier also supplies temperature compensation for the oxygen sensor output. This amplifier circuit incorporates a thermistor, which is physically located in the cell block.

Percent Oxygen Analyzer Operation 4 Operation 4.1 Introduction Once the analyzer has been installed, it can be configured for your application. To do this you will: • • • • Set system parameters: • Establish a security password, if desired, requiring Operator to log in. • Establish and start an automatic calibration cycle, if desired. Calibrate the instrument. Define the three user selectable analysis ranges. Then choose autoranging or select a fixed range of analysis, as required.
4 Operation Model 3000PA 4.2 Using the Data Entry and Function Buttons Data Entry Buttons: The < > arrow buttons select options from the menu currently displayed on theVFD screen. The selected option blinks. When the selected option includes a modifiable item, the ∆ ∇ arrow buttons can be used to increment or decrement that modifiable item. The Enter button is used to accept any new entries on the VFD screen.
Percent Oxygen Analyzer Operation 4 Contrast Function is DISABLED (Refer to Section 1.6) Figure 4-1: Hierarchy of Functions and Subfunctions Each of these functions is described in greater detail in the following procedures. The VFD screen text that accompanies each operation is reproduced, at the appropriate point in the procedure, in a Monospaced type style. Pushbutton names are printed in Oblique type. 4.3 The System Function The subfuctions of the System function are described below.
4 Operation • • • • Model 3000PA activated, the operator MUST enter the UNIQUE password to gain access to set-up functions which alter the instrument's operation, such as setting the instrument span or zero setting, adjusting the alarm setpoints, or defining analysis ranges. After a password is assigned, the operator must log out to activate it. Until then, anyone can continue to operate the instrument without entering the new password. Only one password can be defined.
Percent Oxygen Analyzer Operation 4 4.3.2 Setting up an Auto-Cal When proper automatic valving is connected (see chapter 3, installation), the Analyzer can cycle itself through a sequence of steps that automatically zero and span the instrument. Note: If you require highly accurate Auto-Cal timing, use external Auto-Cal control where possible. The internal clock in the Model 3000PA is accurate to 2-3 %. Accordingly, internally scheduled calibrations can vary 2-3 % per day.
4 Operation Model 3000PA If you have decided not to employ password security, use the default password TBEAI. This password will be displayed automatically by the microprocessor. The operator just presses the Enter key to be allowed total access to the instrument’s features. NOTE: If you use password security, it is advisable to keep a copy of the password in a separate, safe location. 4.3.3.
Percent Oxygen Analyzer Operation 4 Change Password? =Yes =No Press Escape to move on, or proceed as in Changing the Password, below. 4.3.3.2 Installing or Changing the Password If you want to install a password, or change an existing password, proceed as above in Entering the Password.
4 Operation Model 3000PA AAAAA Retype PWD To Verify Wait a moment for the entry screen. You will be given clearance to proceed. AAAAA TO Proceed Use the arrow keys to retype your password and press Enter when finished. Your password will be stored in the microprocessor and the system will immediately switch to the Analyze screen, and you now have access to all instrument functions. If all alarms are defeated, the Analyze screen appears as: 0.
Percent Oxygen Analyzer Operation 4 4.3.5 System Self-Diagnostic Test The Model 3000PA has a built-in self-diagnostic testing routine. Preprogrammed signals are sent through the power supply, output board and sensor circuit. The return signal is analyzed, and at the end of the test the status of each function is displayed on the screen, either as OK or as a number between 1 and 3. (See System Self Diagnostic Test in chapter 5 for number code.
4 Operation 4.4 Model 3000PA The Span Functions The analyzer is calibrated using span gas. NOTE: Zero is not necessary for Percent (%) level measurements. Additional information on ZERO functions is provided in the Appendix A-6 of this manual. Although the instrument can be spanned using air, a span gas with a known oxygen concentration in the range of 70–90% of full scale of the range of interest is recommended. Since the oxygen concentration in air is 20.
Percent Oxygen Analyzer Operation 4 purchased. Then check Cell Replacement in chapter 5 Maintenance, and do the prescribed calculations. If a weak cell is indicated, replace the cell as described there in chapter 5. 4.4.2 Span Cal The Span button on the front panel is used to span calibrate the analyzer. Span calibration can be performed using the automatic mode, where an internal algorithm compares consecutive readings from the sensor to determine when the output matches the span gas concentration.
4 Operation Model 3000PA 4.4.2.2 Manual Mode Spanning Press Span to start the Span function. The screen that appears allows you to select whether the span calibration is to be performed automatically or manually. Span: Settling:MAN For Next Use the ∆∇ keys to toggle between AUTO and MAN span settling. Stop when MAN appears, blinking, on the display. Press Enter to move to the next screen. Span Val: 20.90 Span Mod # Press ∆ () to permit modification (Mod #) of span value.
Percent Oxygen Analyzer Operation 4 The system failure alarm has a fixed configuration described in chapter 3 Installation. The concentration alarms can be configured from the front panel as either high or low alarms by the operator. The alarm modes can be set as latching or non-latching, and either failsafe or non-failsafe, or, they can be defeated altogether. The setpoints for the alarms are also established using this function. Decide how your alarms should be configured.
4 Operation Model 3000PA If you are using password protection, you will need to enter your password to access the alarm functions. Follow the instructions in section 4.3.3 to enter your password. Once you have clearance to proceed, enter the Alarm function. Press the Alarm button on the front panel to enter the Alarm function. Make sure that AL1 is blinking. AL1 AL2 Choose Alarm Set up alarm 1 by moving the blinking over to AL1 using the < > arrow keys. Then press Enter to move to the next screen.
Percent Oxygen Analyzer 4.6 Operation 4 The Range Function The Range function allows the operator to program up to three concentration ranges to correlate with the DC analog outputs. If no custom ranges are defined by the user, the instrument defaults to: Low = 0–1.00 % Med = 0–5.00 % High = 0–10.00 %. The Model 3000PA is set at the factory to default to autoranging. In this mode, the microprocessor automatically responds to concentration changes by switching ranges for optimum readout sensitivity.
4 Operation Model 3000PA 4.6.2 Autoranging Analysis Set your analysis ranges as in 4.6.1, above. Leave Mode in Auto, or use the arrow buttons to change back to Auto. When operating in autoranging, if the oxygen concentration in your sample goes ABOVE your HIGHEST range setting, the analyzer will go into the special 25 % cal range. However, if one of your range settings is below 0-25 % and another is set above 0-25 %, the special 0-25 % Air Cal range will NOT activate as the oxygen level goes through 25 %.
Percent Oxygen Analyzer Operation 4 Press Escape to re-enter the Analyze mode using the fixed range. NOTE:When performing analysis on a fixed range, if the oxygen concentration rises above the upper limit (or default value) as established by the operator for that particular range, the output saturates at 1 V dc. However, the digital readout and the RS-232 output continue to read the true value of the oxygen concentration regardless of the analog output range. 4.
4 Operation Model 3000PA The analog output signal has a voltage which depends on the oxygen 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. To provide an indication of the range, a second pair of analog output terminals are used.

Percent Oxygen Analyzer A-5 Appendix 3000 SERIES ANALYZERS APPLICATION NOTES ON RESTRICTORS, PRESSURES, AND FLOW RECOMMENDATIONS 3000 series analyzers require reasonably regulated sample pressures. While the 3000 analyzers are not sensitive to variations of incoming pressure (provided they are properly vented to atmospheric pressure) the pressure must be maintained as to provide a useable flow rate trough the analyzer. Any line attached to sample vent should be 1/4 or larger in diameter.
Appendix Model 3000PA RESTRICTOR KIT The current revision of the 3000 series analyzers are supplied with a kit containing two restrictors and a union which are user installed. These parts supplied to give the end user more flexibility when installing the analyzer. The restrictor kit is suitable for high and low positive pressure applications as well as vacuum service ( atmospheric pressure sample) applications ( see manual for installation instructions).
Percent Oxygen Analyzer Appendix customer must supply a control valves (or restrictors) for any SPAN or ZERO gas source which is attached to the Auto-Cal ports. The valve should be adjusted to the same flow rate as the sample gas . When restrictors are used, the gas pressure must be adjusted to achieve the proper flow rate. OPERATION WITHOUT A RESTRICTOR DEVICE: Operation without a restrictor device is not recommend as mentioned above. A 3000PA without any flow restrictor device was tested on 11-19-97.
Appendix A-6 Model 3000PA Zero Cal The Zero button on the front panel is used to enter the zero calibration function. Zero calibration can be performed in either the automatic or manual mode. In the automatic mode, an internal algorithm compares consecutive readings from the sensor to determine when the output is within the acceptable range for zero. In the manual mode, the operator determines when the reading is within the acceptable range for zero.
