DESCRIPTION AND SPECIFICATIONS

Instruction Manual

760008-A

September 2001

SECTION 1

1-1 OVERVIEW

This manual describes the Trace Oxygen (TO2) Analyzer Module of Rosemount Analytical's NGA 2000 Series of gas analysis components.

The TO2 Analyzer Module is designed to continuously determine the concentration of trace oxygen in a flowing gaseous mixture. The concentration is expressed in parts-permillion.

The TO2 Analyzer Module is configured as a shelf-mount module, designed to be installed external from the platform on an associated shelf capable of holding two modules side-byside, with gas connections made from the rear. All electronics relative to sample detection and conditioning are included in this module.

1-2 TYPICAL APPLICATIONS

The TO2 Analyzer Module has specific applications in the following areas:

The TO2 Analyzer Module uses the coulometric principle of oxygen detection. This technology is based on the fact that oxygen in the sample is reduced by an electrochemical reaction. This reduction occurs at the cathode and results in the generation of hydroxyl ions. These hydroxyl ions migrate to the anode where they are oxidized to reform oxygen. The oxidation reaction generates four electrons which in turn migrate to the anode to participate in the reduction reaction:

(Cathode Reaction)

+ 2 H2O + 4 e- → 4 OH

O

2

(Anode Reaction)

-

4 OH

→ O2 + 2 H2O + 4 e

A polarizing voltage of approximately 1.3 VDC is applied between the anode and cathode to drive the oxidation and reduction reactions. The resulting current flow produced by the flow of electrons is directly proportional to the oxygen content in the sample gas.

1-4 FEATURES

SECTION 2

INSTALLATION

WARNING.

Before starting to install this equipment, read the Safety Summary in the Preface section of this manual. Failure to follow the safety instructions could result in serious injury or death.

2-1 UNPACKING

If the Trace Oxygen (TO2) Analyzer Module is received as a separate unit, carefully examine the shipping carton and contents for signs of damage. Immediately notify the shipping carrier if the carton or contents is damaged. Retain the carton and packing material until all components associated with the TO2 Analyzer Module are operational.

2-2 ELECTROLYTE

Before installation of the TO2 Analyzer Module, electrolyte must be added to the Sensor. Follow the procedure described in Section 22a.

After addition of electrolyte, locate the analyzer module on an appropriate mounting surface and connect the network cable to either the NETWORK 1 or NETWORK 2 connection on the Analyzer Module, and the NETWORK connection on the Platform network I/O port. (See Figure 2-1 and Figure 2-4.)

a. Electrolyte Addition

Before adding electrolyte to the Sensor, it is recommended to check the Sensor for possible leakage caused by damage in shipment. To check the Sensor for leakage, remove the top cover of the Analyzer Module and locate and remove the 5 mounting screws which hold the Sensor Assembly (Sensor, flow meter, plumbing, inlet/outlet fittings) to the module (see

Figure 4-1). Be careful not to lose these screws as they have metric threads. Carefully lift out the Sensor assembly and remove from the analyzer module. Place on a flat surface and remove the black Sensor cover by unscrewing counterclockwise.

Add distilled or deionized water to the Sensor to the maximum level indication on the Sensor reservoir. Let Sensor stand for approximately 15 minutes and check for leaks around the base of the reservoir, and at the seams and corners. If a leak is found, contact the factory before proceeding. Drain the Sensor.

Fill the Sensor with one bottle of electrolyte supplied with the analyzer module. Use the entire contents of the bottle.

NOTE

Do not add water. The volume and concentration of the bottled electrolyte is pre-measured.

Reinstall the black Sensor cover and carefully reinstall the Sensor Assembly inside the Analyzer Module. Do not tilt the Sensor Assembly excessively as electrolyte may leak out.

2-3 LOCATION

(See Figure 2-2) The TO2 Analyzer Module comes standard with mounting ears for easy installation on flat, horizontal surfaces. Install the TO2 Analyzer Module in a clean, weatherproofed, vibration-free location free from extreme temperature variations and moisture. For best results, install the instrument near the sample stream to minimize sample transport time.

Operating ambient temperature is 0 °C to 45 °C (32 °F to 81 °F). Temperature change should not exceed 10 °C (18 °F) per hour.

Rosemount Analytical Inc. A Division of Emerson Process Management Installation 2-1

Instruction Manual

760008-A September 2001

Model NGA 2000 TO2

The same temperature restrictions apply to the location of the zero and span gas cylinders.

2-4 GASES

a. Requirements

The TO2 Analyzer Module requires only a standard of accurately known composition for use as a span gas. The span gas should be supplied from a cylinder equipped with a clean, metallic diaphragm, two-stage regulator. A shutoff valve is recommended.

Calibration Gases

The TO2 module does not require routine zero calibration. The zero is factory set and does not experience routine drift. Over long periods of time, the zero may experience minor drift. For low ppm range analyzers, you may wish to check the zero at one year intervals. Oxygenfree nitrogen is recommended for use as zero gas. This gas is certified to <0.5 ppm oxygen and can be improved by passing the zero gas through an oxygen scrubber such as Millipore™ Waferpure or Semigas Nanochem® resin purifiers. A mixture of trace oxygen in a background of nitrogen is recommended as span gas. For maximum accuracy, the concentration of trace oxygen in the span gas should be as high as possible for the range of measurement.

Module to control flow, the inlet pressure to the needle valve should not exceed 345 hPa (5 psig). A constant sample flow rate between 1.0 to 3.0 SCFH (0.5 to 1.5 l/min) is recommended for best results. The Analyzer Module must vent to atmosphere to avoid back pressure influences on the oxygen reading.

2-5 GAS CONNECTIONS

(See Figure 2-3. ) Connect inlet and outlet lines for sample to appropriately labeled fittings on the rear panel. SAMPLE IN and SAMPLE OUT are 1/4-inch ferrule-type compression fittings. Zero and span gases should be introduced at the SAMPLE IN fitting at normal sample inlet flow rate.

Metallic tubing is recommended for the sample line. The use of plastic, Teflon, or other non-metallic tubing can result in ambient oxygen permeation through the tubing causing higher than expected reading. Exhaust tubing should be 1/4 inch (6.3 mm) or larger, and can be metallic or non-metallic.

CAUTION.

GAS OVERPRESSURE

At no time should sample, zero or span gas inlet pressure exceed 69 hPa - gauge (1.0 psig). Damage to the Sensor may occur if this pressure level is exceeded.

b. Sample

The sample must be clean and dry before entering the Analyzer Module. Sample should be filtered for particulates down to two microns, and should have a dew point at least 5 °C (13 °F) below the coldest expected ambient temperature.

c. Pressure

Constant between 13.8 and 69 hPa gauge (0.2 and 1.0 psig) sample inlet pressure is recommended. If a needle valve is used upstream of the Analyzer

2-2 Installation Rosemount Analytical Inc. A Division of Emerson Process Management

Do not test the sample pressure by blocking the exhaust. When the pressure is released the sudden surge of flow will spin the internal flowmeter off its bearings and destroy it.

CAUTION.

SAMPLE FLOW

Model NGA 2000 TO2

a. Leak Test

The TO2 Analyzer Module is completely tested at the factory for gas leakage. The user is responsible for testing for leakage only at the inlet and outlet fittings on the rear panel.

CAUTION.

SENSOR DAMAGE

Do not expose the Sensor to pressure in excess of 1.0 psig as this may cause damage.

Flow Indicator Method

Supply air or inert gas such as nitrogen, at 1 psig (6.8 hPa), to the analyzer through a flow indicator with a range of 0 to 250 cc/min. Install a shut-off valve at the sample gas outlet. Set the flow rate to 125 cc/min.

Close the outlet shut-off valve and notice that the flow reading drops to zero. If the flow reading does not drop to zero, the system is leaking and must be corrected before the introduction of sample gas or the application of power.

WARNING.

ELECTRICAL SHOCK HAZARD

Operate this equipment only when covers are secured. Servicing requires access to live parts which can cause death or serious injury. Refer servicing to qualified personnel. For safety and proper performance, this module must be connected to a properly grounded three-wire source of electrical power.

Electrical connections must be made in compliance with National Electrical Code (ANSI/NFPA 70) and/or any applicable national or electrical codes.

Two electrical connections are required on the Analyzer Module: POWER and NETWORK (See Figure 2-4). On the Analyzer Module, two NETWORK connectors are available, either of which is appropriate for: 1) interconnection with the Backplane of the Platform or

2) "daisy-chaining" with other NGA 2000 components (A star connection is acceptable for LON lengths under about 10 meters.)

Connect a source of 24 V 5A DC power to the power inlet. Make sure that the ground connection is made, and that this is separate from the power return lead. Failure to ensure a good ground may result in random noise and disturbance in the analyzer readings.

3-3 STARTUP & INITIALIZATION

Establish sample or zero gas flow through the analyzer module at a nominal flow rate of 2 SCFH (1 l/min). Allow gas to flow for 15 to 30 seconds before applying power. Apply power to the TO2 Analyzer Module.

After switching on the TO2, the analyzer will begin its booting procedure which is apparent on the LCD screen. The first part of the initialization procedure is a self check of the software and analyzer components. Various displays will show the status of the initialization including revision notes, “Initializing network interface,” “Searching for nodes,” “Querying Module: TO2, 12% Complete,” and “Calculating bindings.”

Pressing the F1 key during initializing will reset the LCD brightness and contrast to factory settings (See Section 3-4e). Pressing the F3 key will abort the network initializing, aborting any connection to other analyzers. In that case, only the menus of the local analyzer will be available.

At the end of the initializing routine the “measure” screen will display as shown on the next page. This screen is the access to all other channels, menus and submenus. The actual display may differ from that shown depending on any custom configuration as described in Section 3-5e.

a. Quick Start

This analyzer module is equipped with a quick start feature which allows the sensor to begin measuring low ppm oxygen faster. This feature can be used when the analyzer is first turned on to decrease the time required for the sensor to reach equilibrium. This function is most effective for gas sample measurements below 100 ppm. To maintain sensor life, it is recommended that this feature be used no more than two times in any 24 hour period.

A normal start can take from 2 to 72 hours depending on the concentration being measured. The lower the oxygen concen-

To abort the quick start, move the cursor to the “Exit quick start!” line and press the ↵ key. The quick start process will cease but another quick start should not be attempted until the “Next quick start possible after:” timer reaches zero. This timer provides the means to avoid more than two quick starts in any 24 hour period.

The “Quick Start” function can be accessed from the “Measure” display by pressing F5 (BasicCal) or from the Main Menu as follows:

a. Calibration Procedure

The TO2 analyzer module is fully factory calibrated prior to shipment using certified gas standards. If the analyzer is operated within its specified operating conditions, no regular calibration is required. The zero calibration is very stable and does not require checking more than once a year.

Gas Scale Factor

The Gas Scale Factor is used to correct for background gases other than nitrogen. When the background of the sample is

other than nitrogen, the diffusion rate of oxygen into the sensor changes. By correcting for the background difference, the diffusion change can be compensated in software. The GSF can be entered manually or calculated automatically. Calculation of the GSF requires the user to enter the sample gas composition. In most applications, the GSF is not required. However, some backgrounds exhibit significantly different diffusion characteristics versus nitrogen (such as helium or hydrogen) and the GSF may improve performance.

Set the Gas Scale Factor as follows:

The “Stabel” sensor model contains a special electrolyte that is less susceptible to small concentrations of acids in the sample stream.

Clamp low PVA to 0.02:

This parameter is used for very low oxygen concentration levels where the sensor current may be unstable about zero. Normally this would be set to “No.”

ppm to mg/Nm3 conversion factor:

The ppm to mg/Nm the range of 1 to 100000. The conversion factor depends on the sample gas used.

Lower [Upper] explosion limit (LEL) [UEL]:

The parameters are used for the CLD and PMD modules and do not apply to the TO2 They should both be set at 0.00%.

Temperature compensation at span gas:

This parameter is used to set the upper temperature limit for the sensor which can occur at the upper range of oxygen concentration. The range is 10-1000 and the default setting is 100. When the temperature exceeds this level the module goes into sleep mode.

SECTION 4

DANGER.

ELECTRICAL SHOCK HAZARD

Operate this equipment only when covers are secured. Servicing requires access to live parts which can cause death or serious injury. Refer servicing to qualified personnel. For safety and proper performance, this module must be connected to a properly grounded three-wire source of electrical power.

DANGER.

POSSIBLE EXPLOSION HAZARD

This equipment is not designed and should not be used in the analysis of flammable samples. Use of this equipment in this way could result in explosion and death.

WARNING.

The TO2 Analyzer Module requires very little maintenance during normal operation.

The sensor in the TO2 utilizes a liquid electrolyte. When measuring dry gases, it may be necessary to replenish the liquid by adding distilled or deionized water.

The sensor is designed to hold at least 100 cc of electrolyte. Typically, bone dry sample gas can extract approximately 5-10 cc of water per month from the sensor. It is recommended to check the electrolyte level every 3-4 months to assure that the electrolyte level is within the acceptable operating limits as indicated by the label on the reservoir section of the sensor.

The TO2 analyzer module is equipped with a low electrolyte alarm which indicates when replenishment of the sensor is required. Please refer to the Platform manual for details on configuring alarms.

a. Refilling

To add water:

1. Remove the top cover of the analyzer module.

2. Unscrew the black sensor cover.

3. Slide the cover back just enough to allow the neck of the fill bottle to fit into the sensor reservoir.

4. Add distilled or deionized water using the fill bottle provided with the analyzer module. Fill to approximately midway between the min and max level indicators on the sensor

label. Be careful not to spill water, splash electrolyte or overfill sensor.

5. Replace the sensor cover securely.

6. Replace the top cover of the analyzer module.

If the electrolyte alarm is activated but the sensor shows sufficient electrolyte, the electrolyte may have been contaminated by substances present in the sample which are chemically incompatible with the sensor or electrolyte. If this should occur, the electrolyte must be drained and replaced with fresh electrolyte.

Refer to Section 4-2b for the proper procedure for replacing electrolyte.

Several other components may require replacement. These are discussed in the following sections.

TROUBLESHOOTING

Instruction Manual

760008-A

September 2001

SECTION 5

5-1 TROUBLESHOOTING

The following provides a short list of common troubleshooting tips. Additional information is contained in the Platform Manual.

a. Failure to purge down to ppm levels

Prior to conducting any changes to the system, try running a quick start sequence (see section 3.4) to see if the oxygen reading goes lower. If the reading does decrease, the sensor has not been allowed sufficient time to consume the dissolved oxygen in the electrolyte. If the reading continues to read high a leak may exist in the sample lines. The number one problem associated with trace oxygen analyzer installation is the occurrence of leaks in your sample plumbing. If the oxygen reading will not come down to ppm levels or is reading higher than expected, the sample plumbing prior to the instrument may have a leak. A quick check can be conducted by observing the oxygen reading at two different flow levels; 0.5 and 2.0 scfh. If the oxygen reading drops significantly when the flow is increased from 0.5 to 2.0 scfh, this is a good indication that a leak exists.

To check for leaks prior to the sensor, disconnect the Analyzer Module and cap the inlet line. Pressurize the inlet line to 5

- 10 psig and check all connections with a soapy solution (SNOOP leaks.

®

) to identify

WARNING.

SENSOR DAMAGE

Do not pressure check the sample line with the sensor connected. Overpressurization of the sensor can result in damage.

b. Flow sensitivity

Check to make sure that your vent line is not blocked. If you see a rise in reading with an increase in flow, you may be overpressurizing the sensor due to a blocked vent. Since the sensor is a partial pressure measuring device, an increase in sample pressure will cause an increase in reading. If the reading drops with increased flow, conduct the leak check outlined in the troubleshooting tip above.

c. Erratic and very insensitive readings

Check to see that the electrolyte level is within the limits indicated on the reservoir. Add distilled water as required. If the level is within limits, the electrolyte may have been contaminated. Refer to section 4.2 above for proper procedure to replace electrolyte. If replacement of electrolyte does not improve the performance of the sensor, the sensor may have been damaged due to over-pressurization or poisoning. Sensor replacement may be required as described in section 4.3 above.

ROSEMOUNT WARRANTY

Rosemount warrants that the equipment manufactured and sold by it will, upon shipment, be free of defects in workmanship or material. Should any failure to conform to this warranty become apparent during a period of one year after the date of shipment, Rosemount shall, upon prompt written notice from the purchaser, correct such nonconformity by repair or replacement, F.O.B. factory of the defective part or parts. Correction in the manner provided above shall constitute a fulfillment of all liabilities of Rosemount with respect to the quality of the equipment.

THE FOREGOING WARRANTY IS EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES OF QUALITY WHETHER WRITTEN, ORAL, OR IMPLIED (INCLUDING ANY WARRANTY OF MERCHANTABILITY OF FITNESS FOR PURPOSE).

The remedy(ies) provided above shall be purchaser's sole remedy(ies) for any failure of Rosemount to comply with the warranty provisions, whether claims by the purchaser are based in contract or in tort (including negligence).

Rosemount does not warrant equipment against normal deterioration due to environment. Factors such as corrosive gases and solid particulates can be detrimental and can create the need for repair or replacement as part of normal wear and tear during the warranty period.

Equipment supplied by Rosemount Analytical Inc. but not manufactured by it will be subject to the same warranty as is extended to Rosemount by the original manufacturer.

At the time of installation it is important that the required services are supplied to the system and that the electronic controller is set up at least to the point where it is controlling the sensor heater. This will ensure, that should there be a delay between installation and full commissioning that the sensor being supplied with ac power and reference air will not be subjected to component deterioration.
