Compressed Gas Association1235 Jefferson Davis HighwayArlington, Virginia 22202

Used by Permission

1. Never drop cylinders or permit them to strike each other violently.

2. Cylinders may be stored in the open, but in such cases, should be protected against extremes of weatherand, to prevent rusting, from the dampness of the ground. Cylinders should be stored in the shade whenlocated in areas where extreme temperatures are prevalent.

3. The valve protection cap should be left on each cylinder until it has been secured against a wall or bench, orplaced in a cylinder stand, and is ready to be used.

4. Avoid dragging, rolling, or sliding cylinders, even for a short distance; they should be moved by using asuitable hand-truck.

5. Never tamper with safety devices in valves or cylinders.

6. Do not store full and empty cylinders together. Serious suckback can occur when an empty cylinder isattached to a pressurized system.

7. No part of cylinder should be subjected to a temperature higher than 125°F (52°C). A flame should never bepermitted to come in contact with any part of a compressed gas cylinder.

8. Do not place cylinders where they may become part of an electric circuit. When electric arc welding,precautions must be taken to prevent striking an arc against the cylinder.

Model ROX

SECTION 1DESCRIPTION AND SPECIFICATIONS

1-1 OVERVIEW

This manual describes the ROX GT traceoxygen analyzer and the ROX GP percentoxygen analyzer of the ROX Series of oxygenanalysis instruments.

The ROX GT is designed to determinecontinuously the concentration of traceoxygen in a flowing gaseous mixture. Theconcentration is expressed in parts-per-millionby volume. The ROX GP is designed tomeasure continuously the concentration ofpercent oxygen in a flowing gaseous mixture.

The ROX GT / GP is designed for panelmount or 1/2 19” rack mount, with gasconnections made from the rear. All electronicconnections are also made from the rearincluding the AC power input.

1-2 TYPICAL APPLICATIONS

Typical applications for the ROX GT include:

• Monitoring trace oxygen contamination inpure nitrogen or argon streams from airseparation facilities.

• Determination of trace oxygen content ofinerting atmospheres in heat treat fur-naces.

• Monitoring inert atmosphere glove boxesfor oxygen impurity

Typical applications for the ROX GP include:

• Measuring percent impurities in puregases

• Controlling inerting atmospheres in heattreat applications

• Monitoring oxygen enriching or deficientoperations

1-3 THEORY OF TECHNOLOGY

The ROX GT / GP uses an electrochemicalsensor technology to achieve themeasurement of oxygen. See Figure 1-1,page 1-2. The sensor is a self containeddisposable unit which requires nomaintenance. The sensor utilizes theprinciple of electrochemical reaction togenerate a signal proportional to the oxygenconcentration in the sample.

The sensor consists of a cathode and anodewhich are in contact via a suitable electrolyte.The sensor has a gas permeable membranewhich covers the cathode allowing gas topass into the sensor while preventing liquidelectrolyte from leaking out.

As the sample diffuses into the sensor, anyoxygen present will dissolve in the electrolytesolution and migrate to the surface of thecathode. The oxygen is reduced at thecathode. Simultaneously, an oxidationreaction is occurring at the anode generatingfour electrons. These electrons flow to thecathode to reduce the oxygen.

The representative half cell reactions are:

Cathode:

4e- + 2H2O + O2 → 4OH-

Anode:

4OH- + 2Pb → 2PbO + 2H2O + 4e-

The resultant overall cell reaction is:

2Pb + O2 → 2PbO

This flow of electrons constitutes an electriccurrent which is directly proportional to theconcentration of oxygen present in thesample. In the absence of oxygen, nooxidation / reduction reaction occurs andtherefore no current is generated. This allowsthe sensor to have an absolute zero.

2-4 GASES

During normal operation, the analyzerrequires no support gases. Calibration gasesof air or an appropriate mixture of oxygen innitrogen are recommended (ppm level forROX GT, % level for ROX GP).

After initial startup or startup following aprolonged shutdown, the analyzer mayrequire extended time to recover to the rangeof measurement. Commonly, this is caused bythe introduction of ambient air into the sampleand/or vent lines to the sensor. The presenceof higher than normal levels of oxygen at thesensor will cause the sensor electrolyte tobecome saturated with dissolved oxygen.When the instrument is placed in operation,the sensor must now consume all excessdissolved oxygen above the desiredmeasuring level. This recovery period isrequired only for the ROX GT.

All new external gas tubing is stronglyrecommended, preferably pre-cleaned,stainless steel or copper tubing.

NOTEDo not use plastic tubing for trace oxygenmeasurements as it can permeate oxygenfrom the ambient air and cause higher thanexpected oxygen readings.

ROX GT gas line connections arecompression fittings. Do not use pipe threadtape. ROX GP gas line connections arefemale NPT and the use of pipe thread tape isrecommended.

a. Connections

See Figure 2-2 below. Connect sampleinlet and outlet lines to appropriatelylabeled fittings on the rear panel. Allconnections are 1/4-inch ferrule-typecompression fittings on the ROX GT. TheROX GP has 1/8-inch female NPTconnections.

If sample is available at positive pressureand flow between .1 and 2 SCFH werecommend following the sample handlingconfiguration shown in Figure 2-3, page2-4.

If sample is available at ambient pressureor flow is insufficient to meet minimumflow requirements, we recommendfollowing the sample handlingconfiguration shown in Figure 2-4, page2-4. The inclusion of fast loop bypass,particulate filtration and moisture removalare not shown in these drawings and arethe responsibility of the customer toinclude as required.

b. Gas Specifications

Calibration Gases

Calibration method and gases dependson the desired operating range, andspeed of calibration recovery. Due to thecharacteristics of the sensor, no zero gasis required. In the absence of oxygen, thesensor has an absolute zero.

Span gas can be either air or a certifiedblend of known ppm concentration ofoxygen in nitrogen. All calibration gasesare introduced through the sample inlet atthe rear of the module

Sample Gas

Sample gas should be nonflammable(below 100% of the sample's LEL) andinert. Consult factory if sample gascontains CO2, CO, acid gases, or halogen

gases. These samples may not besuitable for use with this analyzer.

Flow Rate

The sample flow rate can set be between.1 SCFH and 2.0 SCFH (50 - 1000cc/min) without effecting the accuracy ofthe sensor. Sample flow should be set ata constant value within these limits whichprovides the desired response time andsample conservation.

Pressure/Filtration

Sample pressure at the inlet should bewithin the range of 0 to 15 psig (1013 to2048 hPa).

The analyzer does not contain anyintegral sample filtration. Sample shouldbe filtered for particulates down to fivemicrons to reduce the risk of internalsample line blockage.

b. Interconnections

The analyzer has two kinds of outputconnections, a signal output and a set ofrelay contacts. The contacts are rated at115 VAC, but with the following provisos:

There is only "basic insulation (within themeaning of IEC 1010-1) providedbetween the contacts and the rest of thecircuitry. This means that in the event ofa single fault, it is possible that 115 VACconnected to the relay contacts would beconnected to the output connections aswell. Any equipment connected to theanalyzer output may potentially see this115 VAC.

WARNING

ELECTRICAL SHOCK HAZARDThe output connection is for use only withequipment which has no live parts whichare accessible.

The connecting cable and the equipmentto which the output is connected musthave insulation rated for at least 150 VAC,since under fault condition the output maybe connected to the relay contacts witchthemselves may be connected to 150 VAC.

The connection used at the remote end ofthe output circuit must be such as to besuitable for 150 VAC and must have no ac-cessible live parts.

The equipment connected to the outputmust either be approved to IEC 1010-1 orequivalent or must be suitable for use withan input that may potentially be connectedto 150 VAC, and must not catch fire in thiscircumstance.

NOTEThe interconnection terminal strip onthe rear of the analyzer is designed tobe unplugged for easier connection. Itis polarized so that you cannot plug itin backwards. Make the connectionswith plenty of service loop and thenplug it in. Double check that you haveused the correct terminals, and do notapply a high voltage (e.g. 115 V) to therelay contacts before you have verifiedthat the output connections are correct- putting AC on the signal output willdestroy the analyzer.

c. Signal Output Connections

The analyzer comes standard with both 4-20 mA DC isolated and 0-1 VDC outputs.For ease of installation, the signal outputconnections are made via a removableterminal strip connector which is sharedwith the alarm connections (Refer toFigure 2-2, page 2-2).

WARNING

POSSIBLE EXPLOSION HAZARDCheck all wiring connections prior to re-connection of the terminal strip. The ap-plication of AC power to the signal outputterminals will damage the analyzer.

d. Concentration Alarms

The analyzer comes standard with twoconcentration alarms both configured highand normally energized. For ease ofinstallation, the alarm connections aremade via a removable terminal stripconnector which is shared with the signaloutput connections (Refer to Figure 2-2,page 2-2). Each set of alarm connectionsare labeled for easy identification to theassociated alarm. The connectionslabeled NO (normally open), NC (normallyclosed), and C (common) refer to relaypositions with the power removed (de-energized) .

Both alarms are configured from thefactory for fail-safe mode (normallyenergized, and loss of power will cause achange in relay status) and high oxygensetpoint (relay status change abovesetpoint). To change the alarmconfiguration, refer to Section 4-5, page4-6.

e. Off Range Contact

Additionally, there is an off range contactavailable. This contact provides the userwith a contact that changes status whenthe range switch is moved out of thedesired range. This contact comes fromthe factory configured normally energizedon the 0-10 ppm range. In the event of aloss of power or the range switch ismoved to a different position, the contactwill open.

2-6 INSTALLATION GUIDELINES

• Is the analyzer’s location clean, weather-protected, non-hazardous, vibration-free,and with a stable ambient temperature?

SECTION 3OPERATION

3-1 STARTUP

After completion of the installation procedurein Section 2, proceed as follows:

1. Set range switch to the 25% position (fullcounterclockwise)

2. Turn on power by placing the switch onthe power entry module to the “-” position.

3-2 CALIBRATION

See Section 2-4b (page 2-3) for a descriptionof the method for choosing calibration zeroand span gases.

To calibrate the ROX GT/GP, introduce air orspan gas into the SAMPLE INLET, and do thefollowing:

1. Set range switch to the 25% range setting(full counterclockwise) or the appropriaterange for the span gas used. It isrecommended to use the highestconcentration span gas which providesyou with the best fit for your requirements.The use of air for calibration provides theleast chance of span gas error, but doesrequire extended recovery time down tolow ppm level measurement.

2. If you have followed the recommendedsample handling diagram in Section 2-4a,page 2-2. open the sensor isolation valvefirst to avoid exposing the sensor toexcessive sample pressure or vacuum.Flow span gas or air at a floweretbetween 0.1 and 1.0 L/min. Be careful tonot obstruct the outlet as this will causean increase in sample pressure and aconsequent increase in oxygen reading.

NOTEAlarm setpoints are not defeated duringcalibration. Take appropriate precautionsduring calibration.

3. Wait for reading to stabilize. This shouldonly take a few minutes.

4. Locate the SPAN ADJUST potentiometeron the front panel and adjustappropriately to make the displaycorrespond with the span gasconcentration. Turning the potentiometerclockwise will increase the display readingwhile counterclockwise will decrease thereading.

5. If you have used air to span theinstrument, switch to zero gas or sampleas soon as possible to avoid prolongedexposure of the sensor to highconcentrations of oxygen. The longer thesensor is exposed to air, the longer it willtake for the sensor to recover to low ppmlevels. When installing a new sensor orstarting the instrument for the first time, itmay take as long as eight hours for theanalyzer to purge down to the lowestoperating range.

6. Allow the unit to stabilize at the finalreading on zero gas or sample. The unitis now ready for operation.

Unit should be calibrated once a week untilfamiliarity is achieved in required calibrationfrequency. Calibration intervals as long asonce a month are possible on stableinstallations. Processes which have largechanges in environmental conditions andsample composition may require morefrequent calibrations.

3-3 OPERATION

After calibration, proceed as follows:

Supply sample gas to the SAMPLE INLET.Adjust external flow controller or throttle valveso that flow discharged from the outlet isbetween 0.1 and 1.0 L/min.

3-2 Operation Rosemount Analytical Inc. A Division of Emerson Process Management

Model ROX

NOTEFlow indication is not provided with the in-strument and must be provided external tothe analyzer. Refer to Section 2 Installa-tion, for proper location.

When shutting down the instrument, alwaysclose the sensor isolation valve last to avoidexposing the sensor to excessive pressure orvacuum.

3-4 ALARM SETPOINTS

The ROX GT/GP come standard with two fullyadjustable alarms with relay contacts. Thesealarm setpoints are designed to operate aspercent of range as opposed to discreteconcentration value. The alarms areconfigured from the factory as high andfailsafe.

To view the alarm setpoints, turn the rangeswitch to the desired measuring range and

press the “SET LO ALARM” or “SET HIALARM” button. The alarm setpoint will bedisplayed in actual concentration units. Sincethe alarms are configured as percent of scale,changing ranges will also change the value ofthe alarm setpoint. For example, if the LOalarm is set for 5 ppm on the 10 ppm range(50% of range), it will read 50 ppm on the 100ppm range (50% of range).

To adjust the alarm setpoint, press theappropriate alarm setpoint button, then locateand adjust the associated alarm setpointadjustment potentiometer as shown in Figure1-2 and Figure 1-3. Turning the potentiometerclockwise will increase the setpoint whileturning the potentiometer counterclockwisewill decrease the setpoint. You must keep thealarm setpoint button depressed during theadjustment procedure to continuously viewthe alarm setpoint value. Always adjust the“LO” alarm for the lowest setpoint value andthe “HI” alarm for the higher value.

6. If sample is inert (e.g., nitrogen) a lowflow of sample (50 cc/min) can beintroduced to the analyzer to purgeout the internal volume of thecellblock prior to installation of thenew sensor. This procedure is notrequired and is recommended as astep to reduce the purge down time ofthe new sensor.

CAUTION

MAXIMUM FLOWDo not flow a volume in excess of 50cc/min. Exceeding this level may producean oxygen deficient breathing environmentto the technician conducting sensor re-placement. Do not flow sample if it isflammable or toxic. Do not use this proce-dure if the sample handling configurationis for insufficient pressure or flow.

7. Inspect the package containing thereplacement sensor. Do not openthe bag. Make sure that it is thecorrect model type and that there isnot visible liquid in the bag. If the bagcontains liquid, do not open andcontact the factory for a replacement.

8. Locate the shorting tab on the back ofthe sensor. The tab is designed tomaintain contact between the twocontact plates of the sensor while it isstored in the bag. This contact allows

the sensor to continuously consumedissolved oxygen inside the sensor.This clip will need to be removed priorto installing the sensor in theanalyzer.

9. Locate the pull-tab portion of thesensor label. When installing thesensor in the cellblock, make surethat this tab faces forward for easysensor removal later.

10. Cut open the bag being careful not todamage the sensing face of thesensor. Quickly remove the sensorfrom the bag, remove the shorting clipand install in the cellblock with thecontact plates on top and the sensingface on the bottom. Make sure thatthe pull-tab is facing forward and thewriting on the label is right side up(see Figure 4-1, page 4-3).

4-6 TROUBLESHOOTING

The following provides a short list of commontroubleshooting tips.

Analyzer does not power upCheck to make sure that the power cord isproperly installed and the voltage is correctlyselected. The voltage configuration of theanalyzer is visible through the window of thepower entry module. Make sure that thepower switch is in the on position (“-”).

If the unit does not power up, turn off powerswitch, remove power cord and open door onpower entry module as described in Section4.4 above. Inspect fuses and replace asrequired.

Analyzer fails to purge down to ppm levelsThe number one problem associated withtrace oxygen analyzer installation is theoccurrence of leaks in the sample lineplumbing. If the oxygen reading will not comedown to ppm levels or is reading higher thanexpected, the sample plumbing prior to theinstrument may have a leak. A quick checkcan be conducted by observing the oxygenreading at two different flow levels; 0.2 and2.0 SCFH. If the oxygen reading dropssignificantly when the flow is increased from0.2 to 2.0 SCFH, this is a good indication thata leak exists.

To check for leaks prior to the sensor,disconnect the analyzer and cap the inlet andoutlet fittings on the analyzer to reduce theamount of oxygen exposure to the sensor.Cap the inlet line and pressurize the inlet lineto 5 - 10 psig and check all connections with asoapy solution to identify leaks.

WARNING

POSSIBLE SENSOR DAMAGEDo not pressure check the sample linewith the sensor/analyzer connected. Over-pressurization of the sensor can result indamage.

If the reading increases with an increase inflow, the vent line may be obstructed causingback pressure on the sensor. Inspect yourvent line and remove any devices which maybe causing backpressure.

If the reading slowly decreases over time, thesensor may have been exposed to high levelsof oxygen for extended periods of time. Thesensor must consume all of the dissolvedoxygen in the sensor electrolyte before it willaccurately measure ppm levels of oxygen. Insome cases it is not possible for the sensor torecover to low ppm levels and the sensormust be replaced.

Analyzer is reading too lowCheck to make sure that the sensor has beencalibrated properly. Flow an appropriate spangas through the instrument and follow thecalibration procedure in Section 3-2 (page 3-1). If you are unable to achieve spancalibration, the sensor has reached the end ofits useful life and needs to be replaced (seeSection 4-2, page 4-1).

If calibration is possible, but the reading stillappears too low, conduct a span check on the25% range with air. Adjust reading asnecessary. If the reading requiresadjustment, your bottled span gas may beincorrect or corrupted.

If sensor life seems too short, you may havecompounds present in your sample which arepoisoning the sensor. Acid gases, CO2, SO2,or H2S can reduce the life of the sensor andshould be removed from the sample prior tomeasuring.

Model ROX

Analyzer always reads zeroCheck to make sure that the sensor has beeninstalled correctly with the contact plates ontop and the gas permeable membrane facingdownward. If the sensor has been installedincorrectly, carefully remove and check tomake sure that the membrane has not beendamaged. If the sensor is leaking, or showssigns of distress to the membrane, replacewith a new sensor. If the sensor is okayquickly reinstall in the correct position.

Verify that the cellblock contact pins aremaking good contact with the metal surfacesof the sensor. If the pins are not makingcontact, carefully bend the wire down toreestablish contact. Check that the contactpins are clean and do not show signs ofdeposits or oxidation. Clean as necessary.

A good sensor will have an output of 150 to500 micro amps in air. You can check this byconnecting a DVM across the contact plates

of the sensor while it is removed from theinstrument and measuring the current. If thesensor does not produce sufficient output,replace the sensor with a new one.

The readings are erratic and drift noisilyThis is normally an indication that the sensorhas reached the end of its useful life. If theanalyzer cannot be spanned on a cal gas orair, the sensor must be replaced. If thesensor spans okay and appears stable at highoxygen concentrations, there may be asample line leak or obstruction of the ventline. Follow the procedure described above in“Analyzer fails to purge down to ppmlevels”.

If no sample line problems are found, openthe cellblock and inspect the sensor for signsof damage or leakage. Follow the procedurein Section 4-2, page 4-1. for correct method ofopening cellblock and precautions forhandling a leaking sensor.
