SYSTEM OVERVIEW

Scope This Instruction Bulletin is designed to supply details needed to install, start

up, operate, and maintain the Rosemount Analytical Two-Wire In Situ Oxygen Analyzer. The analyzer consists of an oxygen probe and Model 5081 transmitter. The signal conditioning electronics of the Model 5081 transmitter outputs a 4-20 mA signal representing an O control (IRC) allows access to setup, calibration, and diagnostics. This same information, plus additional details, can be accessed with the HART field communicator or Asset Management Solutions (AMS) software.

value. An infrared remote

System Description The Rosemount Analytical Two-Wire In Situ Oxygen Analyzer is designed to

measure the net concentration of oxygen in an industrial process; i.e., the oxygen remaining after all fuels have been oxidized. The oxygen probe is permanently positioned within an exhaust duct or stack and performs its task without the use of a sampling system. The Model 5081 transmitter is mounted remotely and conditions the oxygen probe outputs.

The equipment measures oxygen percentage by reading the voltage developed across a heated electrochemical cell, which consists of a small yttria stabilized, zirconia disc. Both sides of the disc are coated with porous metal electrodes. When operated at the proper temperature, the millivolt output voltage of the cell is given by the following Nernst equation:

EMF = KT log10(P1/P2) + C

Where:

1. P2 is the partial pressure of the oxygen in the measured gas on one side of the cell.

2. P1 is the partial pressure of the oxygen in the reference air on the opposite side of the cell.

3. T is the absolute temperature.

4. C is the cell constant.

5. K is an arithmetic constant.

NOTE

For best results, use clean, dry, instrument air (20.95% oxygen) as the reference air.

NOTE

The probe uses a Type B thermocouple to measure the cell temperature.

When the cell is at operating temperature and there are unequal oxygen concentrations across the cell, oxygen ions will travel from the high oxygen partial pressure side to the low oxygen partial pressure side of the cell. The resulting logarithmic output voltage is approximately 50 mV per decade.

The output is proportional to the inverse logarithm of the oxygen concentration. Therefore, the output signal increases as the oxygen concentration of the sample gas decreases. This characteristic enables the Rosemount Analytical Two-Wire In Situ Oxygen Analyzer to provide exceptional sensitivity at low oxygen concentrations.

Model 5081FG

The oxygen analyzer measures net oxygen concentration in the presence of all the products of combustion, including water vapor. Therefore, it may be considered an analysis on a "wet" basis. In comparison with older methods, such as the portable apparatus, which provides an analysis on a "dry" gas basis, the "wet" analysis will, in general, indicate a lower percentage of oxygen. The difference will be proportional to the water content of the sampled gas stream.

System Configuration The equipment discussed in this manual consists of two major components:

the oxygen probe and the Model 5081 tModel 5081 transmitterransmitter. Oxygen probes are available in three length options, providing in situ penetra-

tion appropriate to the size of the stack or duct. The options on length are 20 in. (508 mm), 26 in. (660 mm), or 38 in. (965 mm).

The Model 5081 transmitter is a two-wire transmitter providing an isolated output, 4-20 mA, that is proportional to the measured oxygen concentration. A customer-supplied 24 VDC power source is required to simultaneously provide power to the electronics and a 4-20 mA signal loop. The transmitter accepts millivolt signals generated by the probe and produces the outputs to be used by other remotely connected devices. The output is an isolated 4-20 mA linearized current.

System Features 1. The cell output voltage and sensitivity increase as the oxygen

concentration decreases.

2. High process temperatures eliminate the need for external cell heating and increase cell accuracy.

3. HART communication is standard. To use the HART capability, you must have either:

(a) Field Communicator (b) Asset Management Solutions (AMS) software for the PC

4. Easy probe replacement due to the light-weight, compact probe design.

5. Remote location of the Model 5081 transmitter removes the electronics from high temperature or corrosive environments.

6. Power is supplied to the electronics through the 4-20 mA line for intrinsic safety (IS) purposes.

7. Infrared remote control (IRC) allows interfacing without exposing the electronics.

a. Infrared Remote Control. The IRC allows access to fault indication

menus on the Model 5081 transmitter LCD display. Calibration can be performed from the IRC keypad.

b. Optional HART Interface (Figure 1-2). The Two-Wire In Situ Oxygen

Analyzer's 4-20 mA output line transmits an analog signal proportional to the oxygen level. The HART output is superimposed on the 4-20 mA output line. This information can be accessed through the following:

• Field Communicator - The field communicator requires Device Description (DD) software specific to the Two-Wire In Situ Oxygen Analyzer. The DD software will be supplied with many field communicators but can also be programmed into existing units at most Fisher-Rosemount Analytical service offices. See Section 4: HART/AMS, for additional HART information.

• Personal Computer (PC) - The use of a personal computer requires AMS software available from Fisher-Rosemount.

9. Selected Distributed Control Systems - The use of distributed control systems requires input/output (I/O) hardware and AMS Security codes are provided to (by infrared remote control) prevent unintended changes to analyzers adjacent to the one being accessed.

10. A calibration check procedure is provided to determine if the Rosemount Analytical Two-Wire In Situ Oxygen Analyzer is correctly measuring the net oxygen concentration in the industrial process.

Handling the Analyzer The probe was specially packaged to prevent breakage due to handling. Do

not remove the padding material from the probe until immediately before installation.

It is important that printed circuit boards and integrated circuits are handled only when adequate antistatic precautions have been taken to prevent possible equipment damage.

The oxygen probe is designed for industrial applications. Treat each component of the system with care to avoid physical damage. Some probe components are made from ceramics, which are susceptible to shock when mishandled.

System Considerations Prior to installing your Rosemount Analytical Two-Wire In Situ Oxygen

Analyzer, make sure you have all the components necessary to make the system installation. Ensure all the components are properly integrated to make the system functional.

After verifying that you have all the components, select mounting locations and determine how each component will be placed in terms of available line voltage, ambient temperatures, environmental considerations, convenience, and serviceability. Figure 1-1 shows a typical system package. A typical system installation is shown in Figure 1-3.

A source of instrument air is optional at the oxygen probe for reference air use. Since the unit is equipped with an in place calibration feature, provisions can be made to permanently connect calibration gas bottles to the oxygen probe.

If the calibration gas bottles will be permanently connected, a check valve is required next to the calibration fittings on the integral electronics.

This check valve is to prevent breathing of the calibration gas line and subsequent flue gas condensation and corrosion. The check valve is in addition to the stop valve in the calibration gas kit.

NOTE:

The electronics is rated NEMA 4X (IP65) and is capable of operation at temperatures up to 65°C (149°F).

Retain the packaging in which the Rosemount Analytical Two-Wire In Situ Oxygen Analyzer arrived from the factory in case any components are to be shipped to another site. This packaging has been designed to protect the product.

PRE-INSTALLATION

Inspect Carefully inspect the shipping container for any evidence of damage. If the

container is damaged, notify the carrier immediately.

Packing List Confirm that all items shown on the packing list are present. Notify

Rosemount Analytical immediately if items are missing.

MECHANICAL INSTALLATION

Avoid installation locations near steam soot blowers.

Locating Oxygen Probe 1. The location of the oxygen probe in the stack or flue is important for

maximum accuracy in the oxygen analyzing process. The probe must be positioned so the gas it measures is representative of the process. Longer ducts may require several analyzers since the O to stratification. A point too near the wall of the duct, or the in-side radius of a bend, may not provide a representative sample because of the very low flow conditions. The sensing point should be selected so the process gas temperature falls within a range of 550° to 1400°C (1022° to 2552°F). Figure 2-1 provides mechanical installation references.

2. Check the flue or stack for holes and air leakage. The presence of this condition will substantially affect the accuracy of the oxygen reading. Therefore, either make the necessary repairs or install the probe upstream of any leakage.

3. Ensure the area is clear of internal and external obstructions that will interfere with installation and maintenance access to the probe. Allow adequate clearance for probe removal (Figure 2-1).

Installing Oxygen Probe

Instruction Manual

The probe was specially packaged to prevent breakage due to handling. Do not remove the padding material from the probe until immediately before installation.

1. Ensure all components are available to install the probe.

NOTE

Leave the probe inner protective cover in place until installation. This is required to protect the ceramic cell during movement.

2. If using an optional adapter plate (Figure 2-2) or an optional mounting flange (Figure 2-3), weld or bolt the component onto the duct. The through hole in the stack or duct wall and refractory material must be 2 in. (50,8 mm) diameter, minimum.

3. If the optional adapter plates are not used, a 2 in. NPT, schedule 40, pipe nipple (Figure 2-4) should be welded to the stack or duct wall. When a 2 in. NPT to 1.25 NPT adapter is threaded to the welded pipe nipple, the adapter provides the pipe threads needed for the probe's process fitting.

4. Where high particulate or slag is in the flue gas stream, it may be desirable to inset the probe in the refractory as shown in Figure 2-5. Use pipe couplings and nipples to adjust the probe insertion depth.

5. Use high temperature material (alumina wool) to seal around the probe during insertion. This prevents hot gases from escaping or cold air from entering the stack or duct.

6. Initially insert the probe to a depth of 3 in. (76,2 mm) or 1/2 the depth of the stack or duct refractory, whichever is greater.

2-4

After initial insertion, do not insert the probe at a rate exceeding 1 in. per minute (25.4 mm per minute) or damage to the probe may result due to thermal shock.

7. After initial insertion, insert the probe at a rate of 1 in. (25,4 mm) per minute until the probe is fully inserted.

8. Install anti-seize compound on the pipe threads and screw the probe into the process flange or adapter.

9. If insulation was removed to access the duct work for probe mounting, make sure the insulation is replaced. See Figure 2-4.

If the ducts will be washed down during outage, MAKE SURE to power down the probes and remove them from the wash area.

ELECTRICAL INSTALLATION

All wiring must conform to local and national codes.

For intrinsically safe applications, refer to the installation drawings in Appendix C of this Instruction Manual.

Disconnect and lock out power before connecting the unit to the power supply.

Install all protective equipment covers and safety ground leads after installation. Failure to install covers and ground leads could result in serious injury or death.

To meet the Safety Requirements of IEC 1010 (EC requirement), and ensure safe operation of this equipment, connection to the main electrical power supply must be made through a circuit breaker (min 10 A) which will disconnect all current-carrying conductors during a fault situation. This circuit breaker should also include a mechanically operated isolating switch. If not, then another external means of disconnecting the supply from the equipment should be located close by. Circuit breakers or switches must comply with a recognized standard such as IEC 947.

General The power supply and signal wiring should be shielded. Also, make sure the

signal wiring is grounded at the Model 5081 transmitter end only. Do not ground the signal loop at more than one point. Twisted pairs are recommended. Ground the transmitter housing to an earth ground to prevent unwanted electromagnetic interference (EMI) or radio frequency interference (RFI).

NOTE

For optimum EMI/RFI immunity, shield the 4-20 mA current loop cable and enclose in an earth grounded metal conduit.

NOTE

Never run signal or sensor wiring in the same conduit, or open tray, with power cables. Keep signal or sensor wiring at least 12 in. (0,3 m) away from other electrical equipment and 6.5 ft (2 m) from heavy electrical equipment.

Verify Mechanical Installation

Ensure the Two-Wire In Situ Oxygen Analyzer is installed correctly. See Mechanical Installation in Section 2: Installation for mechanical installation information.

Verify Terminal Block Wiring

Ensure the wiring of both the oxygen probe terminal block and Model 5081 transmitter terminal block is correct. Refer to Electrical Installation in Section 2: Installation for electrical installation and wiring information.

POWER UP General

The Two-Wire In Situ Oxygen Analyzer displays the current oxygen reading on the LCD face of the Model 5081 transmitter. The O temperature, and 4-20 mA output current are displayed as shown in Figure 3-1. This and other information may also be accessed using HART/AMS.

Startup Display

When the probe is first inserted into the stack, some time is required until the minimum operating temperature [550°C (1022°F)] is reached. Some time is also required for the electronics to reach an operating state. Therefore, when the unit is first powered up, a faulted operation display as shown in Figure 3-2 may be displayed by the transmitter until the probe operating temperature is reached and the electronics are working properly (approximately 5 minutes).

OVERVIEW The HART field communicator is a handheld communications interface

device. It provides a common communications link to all microprocesor-based instruments that are HART compatible. The field communicator has a liquid crystal display (LCD) and keypad. A pocket-sized manual, included with the field communicator, details the specific functions of the keypad keys.

To interface with the Model 5081FG Analyzer, the field communicator requires a termination point along the 4-20 mA current loop and a minimum load resistance of 250 ohms between the field communicator and the power supply.

The field communicator accomplishes its task using a frequency shift keying (FSK) technique. With the use of FSK, high-frequency digital communication signals are superimposed on the analyzer's 4-20 mA current loop. The field communicator does not disturb the 4-20 mA signal, since no net energy is added to the loop.

The field communicator may be interfaced with a personal computer (PC), providing that special software has been installed. To connect the field communicator to a PC, an interface adapter is required. Refer to the proper field communicator documentation regarding the PC interface option.

FIELD COMMUNICATOR PC CONNECTIONS

OFF-LINE AND ON-LINE OPERATIONS

There is an option to interface the field communicator with a personal computer. Refer to the applicable field communicator documentation regarding the PC interface option.

The field communicator can be operated both off-line and on-line. Off-line operations are those in which the communicator is not connected to

the Model 5081FG Analyzer. Off-line operations can include interfacing the field communicator with a PC (refer to applicable HART documentation regarding HART/PC applications.

In the on-line mode, the communicator is connected to the 4-20 mA analog output signal line. The communicator is connected in parallel to the Model 5081FG Analyzer or in parallel to the 250 ohm load resistor.

NOTE

If the field communicator is turned on while connected to the 4-20 mA analog output signal line, an undefined status indication appears while the communicator warms up. Wait until the warm-up period ends to continue.

The opening menu displayed on the LCD is different for on-line and off-line operations. When powering up a disconnected (off-line) communicator, the LCD will display the Main Menu. When powering up a connected (on-line) communicator, the LCD will display the On-line Menu. Refer to the field communicator manual for detailed menu information.

GENERAL This troubleshooting section describes how to identify and isolate faults that

may develop in the Two-Wire In Situ Oxygen Analyzer.

PROBE LIFE The zirconium oxide technology for measuring oxygen is very stable and

should provide accurate service for several years. Life of the probe is negatively impacted by:

• Continued operation at elevated temperatures above 1300°C (2372°F).

• Operation in processes that contain high levels of sulfur, SO acidic compounds.

, or other

Operating conditions with simultaneously high levels of SO O

are particularly damaging.

The health and accuracy of a given cell is closely related to the resistance, or impedance, of the cell. Figure 5-1 illustrates that the amount of output from a cell for a given O point where cell impedance increases to approximately 100 ohms.

Frequently conduct calibration checks to look for the following conditions:

• Continued degradation of cell slope.

• Sluggish response. (Note how long it takes the cell to respond to the application of calibration check gases.) See Figure 5-2.

The slope will be valid only for the process temperature at which the calibration check gases are flowed, so no adjustments to the electronics are made as a result of a calibration check.

Note that cells exposed to temperatures above 1300°C (2372°F) may lose the ability to measure accurately and respond quickly when returned to the lowest end of the operating temperature range [550°C (1022°F)].

OLULINE TEAVE

Juhtmestiku ja seadme paigaldamisega seotud ohutusjuhised Alljärgnevad ohutusjuhised rakenduvad eriti kõigi Euroopa Liidu

liikmesriikide suhtes. Antud juhiseid tuleb täpselt järgida, et kindlustada vastavus madalpinge direktiiviga. Euroopa Liitu mittekuuluvad riigid peavad samuti alljärgnevaid juhiseid järgima, va juhul, kui on olemas vastavad kohalikud riiklikud standardid.

1. Ettenähtud maanduspunktide, nii sisemiste kui väliste jaoks tuleb tagada nõuetekohased maaühendused.

2. Pärast paigaldamist või rikketuvastust tuleb kõik turvaümbrised ja turvamaandused uuesti oma kohale seada. Kõigis olukordades tuleb säilitada kõigi maandusklemmide terviklikkus.

3. Toitejuhtmed peavad vastama IEC227 või IEC245 nõuetele.

4. Kogu juhtmestik peab sobima kasutamiseks üle 75°C õhutemperatuuri juures.

5. Kõik juhtmetihendid peavad sisemõõtmete poolest tagama nõuetekohased kaabliühendused.

6. Seadme ohutu töötamise tagamiseks peab ühendus toiteallikaga toimuma vaid läbi automaatkorgi, mis veaolukorras lülitab välja kõik voolukandjad. Automaatkorgil võib olla ka mehhaaniliselt reguleeritav lahklüliti. Vastasel juhul peab seadme toiteallikast lahtiühendamiseks olema teine ja selgelt osutatud moodus. Automaatkorgid või -lülitid peavad vastama tunnustatud standarditele nagu nt IEC947. Kogu juhtmestik peab vastama kohalikele standarditele.

7. Seadmel või ümbristel asuv paremale osutav sümbol tähistab selle all leiduvat ohtlikku pinget. Selliste sümbolitega ümbriseid võib eemaldada vaid juhul, kui seade on toiteallikast lahti ühendatud ning ka siis ainult vastavate oskustega spetsialisti poolt.

8. Seadmele või ümbristele märgitud paremale osutava sümboli all valitseb kuumadest pindadest tulenev oht. Nimetatud sümbolitega ümbriseid võib eemaldada vaid vastavate oskustega spetsialist, kui seade on toiteallikast lahti ühendatud. Teatud pinnad võivad puudutamise jaoks liiga kuumad olla.

9. Seadmel või ümbristel leiduva paremale osutava sümboli korral vt juhiste jaoks Toimimisjuhendit.

10. Kõik selle toote juures kasutatavad graafilised sümbolid lähtuvad ühest või enamast järgmistest standarditest: EN61010-1, IEC417 ja ISO3864.

11. Kui seadmele või siltidele on kirjutatud "Ärge avage voolutarbimine korral" vms, valitseb plahvatusohtlikus keskkonnas süttimise oht. Seadet võib avada ainult siis, kui toide on lahti ühendatud ning seadmel on võimaldatud sildil või kasutusjuhendis osutatud aja jooksul maha jahtuda -- ning ka sellisel juhul ainult vastavate oskustega spetsialisti poolt.
