Percent Oxygen Analyzer Operational Theory 2 Operational Theory 2.1 Introduction The analyzer is composed of three subsystems: 1. Paramagnetic 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 3000MA bell to the zero position in the presence of zero gas (i.e. no O2 present) or of sample gas is proportional to the partial pressure of oxygen in the sample gas. The sensor enclosure is temperature controlled to 55 degrees centigrade to insure that the magnetic susceptibility of oxygen in the sample is not affected by the ambient temperature.

Depending on the mode of operation either sample or calibration gas is delivered. The Model 3000MA sample system is designed and fabricated to ensure that the oxygen concentration of the gas is not altered as it travels through the sample system.
2 Operational Theory 2.5 Model 3000MA Electronics and Signal Processing The Model 3000MAPercent Oxygen Analyzer uses an 8031 microcontroller with 32 kB of RAM and 128 kB of ROM to control all signal processing, input/output, and display functions for the analyzer. System power is supplied from a universal power supply module designed to be compatible with any international power source. Figure 2-6 shows the location of the power supply and the main electronic PC boards.

Percent Oxygen Analyzer Installation 3 Installation Installation of the Model 3000MA Analyzer includes: 1. Unpacking 2. Mounting 3. Gas connections 4. Electrical connections 5. Testing the system. 3.1 Unpacking the Analyzer The analyzer is shipped with all the materials you need to install and prepare the system for operation. Carefully unpack the analyzer and inspect it for damage. Immediately report any damage to the shipping agent. 3.
3 Installation Model 3000MA Latch Analyze System Span Zero Alarms Range 2.0 1.0 Hinge Enter Escape 6.7” 3000MA OXYGEN ANALYZER 10” Figure 3-1: Front Panel of the Model 3000MA All operator controls are mounted on the control panel, which is hinged on the left edge and doubles as the door that provides access to the sensor inside the instrument.
Percent Oxygen Analyzer Installation 3 Figure 3-3: Rear Panel of the Model 3000MA 3.3.1 Gas Connections It is recommended that a gas filter be located upstream of the 3000MA to prevent sensor or restrictor contamination. A 0.5 micron filter should be suitable. Before using this instrument, it should be determined if the unit will be used for pressurized service or vacuum service and low pressure applications. Inspect the restrictor kit that came with the unit.
3 Installation Model 3000MA The unit is manufactured with 1/4 inch tube fittings. Six millimeter adapters are available for metric system installations. For a safe connection: 1. Insert the tube into the tube fitting, and finger-tighten the nut until the tubing cannot be rotated freely, by hand, in the fitting. (This may require an additional 1/8 turn beyond finger-tight.) 2. Hold the fitting body steady with a backup wrench, and with another wrench rotate the nut another 1 1/4 turns.
Percent Oxygen Analyzer Installation 3 Primary Input Power: The power cord receptacle and fuse block are located in the same assembly. Insert the female plug end of the power cord into the power cord receptacle. CAUTION: Power is applied to the instrument's circuitry as long as the instrument is connected to the power source. The switch on the front panel is for switching power on or off to the displays and outputs only. The universal power supply requires a 100-240 VAC, 50/60 Hz power source.
3 Installation Model 3000MA Figure 3-4: Analog Output Connections Alarm Relays: The three alarm-circuit connectors are spring terminals for making connections to internal alarm relay contacts. Each provides a set of Form C contacts for each type of alarm. Each has both normally open and normally closed contact connections. The contact connections are indicated by diagrams on the rear panel. They are capable of switching up to 3 amperes at 250 V ac into a resistive load. See Figure 3-5.
Percent Oxygen Analyzer Installation 3 Digital Remote Cal Inputs: Accept 0 V (off) or 24 V dc (on) inputs for remote control of calibration. (See Remote Calibration Protocol below.) Zero: Floating input. A 5 to 24 V pulse input across the + and – terminals puts the analyzer into the Zero mode. Either side may be grounded at the source of the signal. A synchronous signal must open and close the external zero valve appropriately. See 3.3.3 Remote Probe Connector.
3 Installation Model 3000MA Note: The Remote Probe connector (paragraph 3.3.3) provides signals to ensure that the zero and span gas valves will be controlled synchronously. If you have the –C Internal valve option—which includes additional zero and span gas inputs— the 3000MA automatically regulates the zero, span and sample gas flow. Range ID Relays: Four dedicated Range ID relay contacts.
Percent Oxygen Analyzer st Installation 3 Toggling input. Stops/Starts any status message output from the RS-232, until st is sent again. The RS-232 protocol allows some flexibility in its implementation. Table 3-2 lists certain RS-232 values that are required by the 3000MA implementation.

3 Installation Model 3000MA Figure 3-7: FET Series Resistance 3.4 Testing the System Before plugging the instrument into the power source: • Check the integrity and accuracy of the gas connections. Make sure there are no leaks. • Check the integrity and accuracy of the electrical connections. Make sure there are no exposed conductors. • Check that sample pressure is between 3 and 15 psig, according to the requirements of your process.
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 3000MA 4.2 Using the Data Entry and Function Buttons Data Entry Buttons: The < > arrow buttons select options from the menu currently 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.
Percent Oxygen Analyzer Operation 4 Contrast Function is DISABLED (Refer to Section 1.6) Figure 4-1: Hierarchy of Functions and Subfunctions duced, 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. Specific procedures for their use follow the descriptions: • • Auto-Cal: Used to define an automatic calibration sequence and/or start an Auto-Cal.
4 Operation • • • • Model 3000MA 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. Before a unique password is assigned, the system assigns TBEAI by default. This allows access to anyone.
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 3000MA is accurate to 2-3 %. Accordingly, internally scheduled calibrations can vary 2-3 % per day.
4 Operation Model 3000MA 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 3000MA A A A A A 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 3000MA 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 3000MA 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.
Percent Oxygen Analyzer Operation 4 Press Enter to move to the next screen. Span Val: 20.90 Span Mod # Use the ∆ ∇ arrow keys to enter the oxygen-concentration mode. Use the < > arrow keys to blink the digit you are going to modify. Use the ∆ ∇ arrow keys again to change the value of the selected digit. When you have finished typing in the concentration of the span gas you are using (20.90 if you are using air), press Enter to begin the Span calibration.
4 Operation Model 3000MA for the first Slope value to display. Slope indicates rate of change of the Span reading. It is a sensitive indicator of stability. #### % Span Slope=#### ppm/s When the Span value displayed on the screen is sufficiently stable, press Enter. (Generally, when the Span reading changes by 1 % or less of the full scale of the range being calibrated for a period of five minutes it is sufficiently stable.) Once Enter is pressed, the Span reading changes to the correct value.
Percent Oxygen Analyzer Operation 4 In failsafe mode, the alarm relay de-energizes in an alarm condition. For non-failsafe operation, the relay is energized in an alarm condition. You can set either or both of the concentration alarms to operate in failsafe or non-failsafe mode. 3. Are either of the alarms to be latching? In latching mode, once the alarm or alarms trigger, they will remain in the alarm mode even if process conditions revert to non-alarm conditions.
4 Operation • • • • Model 3000MA To define the setpoint, use the < > arrow keys to move the blinking over to AL–1 ####. Then use the ∆∇ arrow keys to change the number. Holding down the key speeds up the incrementing or decrementing. (Remember, the setpoint units are percent-of-oxygen.) To set the other parameters use the < > arrow keys to move the blinking over to the desired parameter. Then use the ∆∇ arrow keys to change the parameter.
Percent Oxygen Analyzer Operation 4 4.6.1 Setting the Analog Output Ranges To set the ranges, enter the range function mode by pressing the Range button on the front panel. L1.00 M5.00 H10.00 ModeAUTO Use the < > arrow keys to blink the range to be set: low (L), medium (M), or high (H). 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.
4 Operation Model 3000MA To switch from autoranging to fixed range analysis, enter the range function by pressing the Range button on the front panel. Use the < > arrow keys to move the blinking over AUTO. Use the ∆∇ arrow keys to switch from AUTO to FX/LO, FX/MED, or FX/HI to set the instrument on the desired fixed range (low, medium, or high). L1.00 M5.00 H10.00 ModeFX/LO or L1.00 M5.00 H10.00 ModeFX/MED or L1.00 M5.00 H10.
Percent Oxygen Analyzer Operation 4 The signal output for concentration is linear over the currently selected analysis range. For example, if the analyzer is set on range that was defined as 0–10 % O2, then the output would be: % O2 Voltage Signal Output (V dc) 0 1 2 3 4 5 6 7 8 9 10 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 Current Signal Output (mA dc) 4.0 5.6 7.2 8.8 10.4 12.0 13.6 15.2 16.8 18.4 20.
