(The sample system and Micro-Fuel Cell sensor are covered in Part II, Analysis Unit, in this manual.
2 Operational Theory Model 3010PAC Figure 2-1: Block Diagram of the 3010PAC CU Electronics 2-2: Part I Teledyne Analytical Instruments
Oxygen Analyzer Part I: Control Unit The digital concentration signal—along with input from the control panel—is processed by the microprocessor, and appropriate control signals are directed to the display, alarms and communications port as well as to the optional gas control valves in the Analysis Unit.
2 Operational Theory 2-4: Part I Teledyne Analytical Instruments Model 3010PAC
Oxygen Analyzer Part I: Control Unit Installation Installation of Model 3010PAC Analyzers includes: 1. Unpacking, mounting, and interconnecting the Control Unit and the Analysis Unit 2. Making gas connections to the system 3. Making electrical connections to the system 4. Testing the system. This chapter covers installation of the Control Unit. (Installation of the Analysis Unit is covered in Part II of this manual.) 3.
3 Installation Model 3010PAC Figure 3-1: Front Panel of the Model 3010 Control Unit Figure 3-2: Single and Dual 19" Rack Mounts All operator controls are mounted on the control panel, which is hinged on the left edge and doubles as a door to provide access to the internal components of the instrument.
Oxygen Analyzer Part I: Control Unit is pressed all the way in with a narrow gauge tool (less than 0.18 inch wide), such as a small hex wrench or screwdriver Allow clearance for the door to open in a 90-degree arc of radius 7.625 inches. See Figure 3-3. Figure 3-3: Required Front Door Clearance 3.3 Electrical Connections Figure 3-4 shows the Control Unit rear panel. Connections for power, communications, and both digital and analog signal outputs are described in the following paragraphs.
3 Installation Model 3010PAC CAUTION: Use Shielded Cables. Also, use plugs that provide excellent EMI/RFI protection. The plug case must be connected to the cable shield, and it must be tightly fastened to the analyzer with its fastening screws. Ultimately, it is the installer who ensures that the connections provide adequate EMI/RFI sielding. 3.3.1 Primary Input Power The universal power supply requires a 85–250 V ac, 47-63 Hz power source.
Oxygen Analyzer Part I: Control Unit Analog Outputs: There are four DC output signal pins—two pins per output. For polarity, see Table 3-1. The outputs are: 0–1 V dc % of Range: Voltage rises linearly with increasing oxygen, from 0 V at 0 ppm to 1 V at full scale ppm. (Full scale = 100% of programmable range.) 0–1 V dc Range ID: 0.25 V = Low Range, 0.5 V = Medium Range, 0.75 V = High Range, 1 V = Air Cal Range.
3 Installation Model 3010PAC • Can be configured as failsafe or nonfailsafe. • Can be configured as latching or nonlatching. • Can be configured out (defeated). Actuates when DC power supplied to circuits is unacceptable in one or more parameters. Permanently configured as failsafe and latching. Cannot be defeated. Actuates if self test fails. System Alarm: (Reset by pressing button to remove power. Then press again and any other button EXCEPT System to resume.
Oxygen Analyzer Part I: Control Unit synchronous signal must open and close external span valve appropriately. See Figure 3-5 Remote Probe Connector. (The –C option internal valves operate automatically.) Cal Contact: This relay contact is closed while analyzer is spanning and/or zeroing. (See Remote Calibration Protocol below.
3 Installation Model 3010PAC option—which includes additional zero and span gas inputs— the 3000PAC automatically regulates the zero, span and sample gas flow. Range ID Relays: Four dedicated Range ID relay contacts. The first three ranges are assigned to relays in ascending order— Low range is assigned to Range 1 ID, Medium range is assigned to Range 2 ID, and High range is assigned to Range 3 ID. The fourth range is reserved for the Air Cal Range (25%). Table 3-4 lists the pin connections.
Oxygen Analyzer Part I: Control Unit The voltage from these outputs is nominally 0 V for the OFF and 15 V dc for the ON conditions. The maximum combined current that can be pulled from these output lines is 100 mA. (If two lines are ON at the same time, each must be limited to 50 mA, etc.) If more current and/or a different voltage is required, use a relay, power amplifier, or other matching circuitry to provide the actual driving current.

3 Installation 3-12: Part I Model 3010PAC Teledyne Analytical Instruments
Oxygen Analyzer Part I: Control Unit Operation 4.1 Introduction Once the analyzer has been installed, configure it for your process. To do this you can: • • • • Set system parameters— • Specify a 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 3010PAC 4.2 Using the Data Entry and Function Buttons Data Entry Buttons: The < > arrow buttons select options from the menu currently being displayed on the VFD 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.
Oxygen Analyzer Part I: Control Unit Contrast Function is DISABLED (Refer to Section 1.3) 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 subfunctions of the System function are described below.
4 Operation • • • • Model 3010PAC 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.
Oxygen Analyzer Part I: Control Unit 4.3.2 Setting up an Auto-Cal When the proper calibration gases are 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 3010PAC is accurate to 2-3 %. Accordingly, internally scheduled calibrations can vary 2-3 % per day.
4 Operation Model 3010PAC 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.
Oxygen Analyzer Part I: Control Unit 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 3010PAC When you have finished typing the new password, press Enter. A verification screen appears. The screen will prompt you to retype your password for verification. AAAAA Retype PWD To Verify Wait a moment. The entry screen will give you clearance to proceed. AAAAA TO Proceed Use the arrow keys to retype your password and press Enter when finished.
Oxygen Analyzer Part I: Control Unit 4.3.5 System Self-Diagnostic Test The Model 3010PAC 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 Model 3010PAC 4.3.6 Version Screen Move the < > arrow key to More and press Enter. With Version blinking, press Enter. The screen displays the manufacturer, model, and software version information. 4.4 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-5 of this manual.
Oxygen Analyzer Part I: Control Unit Version Self—Test Cell Output: ### µA The “good” reading depends on the class of cell your analyzer is using. Although the B-1 cell is standard in the 3010PAC, check Specific Model Information in the Front Matter in this manual for the class of cell you purchased. Then check Cell Replacement in Part II Analysis Units, 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.
4 Operation Model 3010PAC tion on Slope. Spanning automatically ends when the span output corresponds, within tolerance, to the value of the span gas concentration. Then the instrument automatically returns to the analyze mode. 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.
Oxygen Analyzer 4.5 Part I: Control Unit The Alarms Function The Model 3010PAC is equipped with 2 fully adjustable concentration alarms and a system failure alarm. Each alarm has a relay with a set of form C contacts rated for 3 amperes resistive load at 250 V ac. See figure in chapter 3, Installation and/or the Interconnection Diagram included at the back of this manual for relay terminal connections. The system failure alarm has a fixed configuration described in chapter 3 Installation.
4 Operation Model 3010PAC The defeat alarm mode is incorporated into the alarm circuit so that maintenance can be performed under conditions which would normally activate the alarms. The defeat function can also be used to reset a latched alarm. (See procedures, below.) 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.
Oxygen Analyzer Part I: Control Unit Go to Ltch– and then press either ∆ two times or ∇ two times. (Toggle it to N and back to Y.) 4.6 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 ranges are defined by the user, the instrument defaults to: Range Limits Low Med High 0–1 % 0–5 % 0–10 %. The Model 3010PAC is set at the factory to default to autoranging.
4 Operation Model 3010PAC Use the ∆∇ arrow keys to enter the upper value of the range (all ranges begin at 0 %). Repeat for each range you want to set. Press Enter to accept the values and return to Analyze mode. (See note below.) Note: The ranges must be increasing from low to high, for example, if range 1 is set for 0–10 % and range 2 is set for 0–100 %, range 3 cannot be set for 0–50 % since it is lower than range 2. 4.6.
Oxygen Analyzer 4.7 Part I: Control Unit The Analyze Function When the Analyze function is active, the 3010PAC is monitoring the sample gas currently flowing in the Analysis Unit cell block. All undefeated alarms are ready to activate should their respective setpoints be crossed. Press the Analyze button to put the analyzer in the Analyze mode. Normally, all of the functions automatically switch back to the Analyze function when they have completed their assigned operations.
4 Operation Model 3010PAC Interpretation of the analog output signal depends on the voltage (or current) 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.
Part I: Control Unit Maintenance 5 Maintenance Aside from normal cleaning and checking for leaks at the gas connections, routine maintenance is limited to replacing Micro-Fuel cells and fuses, and recalibration. Checking for leaks, replacing Micro-Fuel cells, and replacing fuses in the Analysis Unit are covered in Part II, Chapter 5. For recalibration, see Part I, section 4.4 Calibration.

Oxygen Analyzer Part II: Analysis Unit Introduction 1.1 Overview The Analytical Instruments Model 3010PAC Remote Probe is a versatile remotely controlled instrument for detecting percent amounts of oxygen (0-1% to 0-100%) in a variety of background gases. Details are recorded in Specifications in the Appendix to this manual. The analyzer is designed to meet the CENELEC operation standards for European use.
1 Introduction Model 3010PAC CAUTION: Bypassing the barriers in any way nullifies their effect, and conditions which prompted their use will prevail. If the instrument is used under any conditions contrary to the intrinsic safety design, the user assumes all risk. 1.3 Area Classification The control unit and barrier box are general purpose units and must be located in a non-hazardous location.
Oxygen Analyzers Part II: Analysis Units Operational Theory 2.1 Introduction The Analysis Unit is composed of two subsystems: the Micro-Fuel Cell sensor and the sample system. The Micro-Fuel Cell is an electrochemical galvanic device that translates the amount of oxygen present in the sample into an electrical current.
2 Operational Theory Model 3010PAC being 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 A Micro-Fuel Cell (MFC) is a cylinder only 1¼ inches in diameter and 1¼ inches thick. It is made of an extremely inert plastic, which can be placed confidently in practically any environment or sample stream.
Oxygen Analyzers Part II: Analysis Units At the top end of the cell is a diffusion membrane of Teflon, whose thickness is very accurately controlled. Beneath the diffusion membrane lies 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.
2 Operational Theory Model 3010PAC The overall reaction for the fuel cell is the SUM of the half reactions above, or: 2Pb + O2 → 2PbO (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.
Oxygen Analyzers Part II: Analysis Units Figure 2-3. Characteristic Input/Output Curve for a Micro-Fuel Cell 2.2.6 Micro-Fuel Cell “Class” TAI manufactures Micro-Fuel Cells with a variety of characteristics to give the best possible performance for any given sample conditions. A few typical Micro-Fuel Cells are listed below with their typical use and electrical specifications. 2.2.6.
2 Operational Theory Model 3010PAC 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. 2.2.6.4 Class B-3 Cell The class B-3 cell is for use in applications where a slightly longer response time is acceptable in order to have a longer cell life. Nominal output in air is 0.
Oxygen Analyzer Part II: Analysis Unit Installation Installation of the Model 3010PAC Analyzer includes: 1. Unpacking, mounting, and interconnecting the Control Unit and the Analysis Unit 2. Making gas connections to the system 3. Making electrical connections to the system 4. Testing the system. 3.1 Unpacking the Analysis Unit The analyzer is shipped with all materials needed to install and prepare the system for operation.

4 Maintenance Model 3010PAC Check Specific Model Information in the Front Matter in this manual for the class of cell you purchased. Then check Table 5-1, the cell index table below, and do the simple calculation. If the resulting value is below the Cell Output reading, replace the cell. To find out if your cell is too weak: 1. Flow span gas through the analyzer, and allow time to purge. 2. With span gas flowing, read the raw output of the cell from the System function display. 3.
Oxygen Analyzer Part II: Analysis Unit If a cell was working satisfactorily, but ceases to function before the warranty period expires, the customer will receive credit toward the purchase of a new cell. If you have a warranty claim, you must return the cell in question to the factory for evaluation. If it is determined that failure is due to faulty workmanship or material, the cell will be replaced at no cost to you.
