GENERAL PRECAUTIONS FOR HANDLING AND STORING HIGHPRESSURE GAS CYLINDERS

Edited from selected paragraphs of the Compressed Gas Association's "Handbook of CompressedGases" published in 1981

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 when lo-cated 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 a suit-able 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 is at-tached 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, precau-tions must be taken to prevent striking an arc against the cylinder.

Rosemount Analytical Inc. A Division of Emerson Process Management Description and Specifications 1-1

Model 7003M

SECTION 1DESCRIPTION AND SPECIFICATIONS

1-1 OVERVIEW

The Model 7003M Percent Oxygen Analyzercontinuously monitors the concentration ofoxygen in a gaseous sample. It consists of asensor and the analyzer. The sensor ishoused in a chamber assembly and isconnected to the analyzer by a shielded multi-conductor cable.

The Model 7003M Percent Oxygen Analyzerprovides direct digital readout, isolated current

output, automatic temperature compensationcircuitry, and dual relay contact closures foralarms or ON/OFF control devices asstandard features. The alarm ranges can beselected independently from the output range,eliminating the need to readjust alarmsetpoints if the range is changed.

The analyzer has six modes of operation:

MODE FUNCTIONRUN (see Section 3-4 on page 3-10) Normal monitoringSETUP (see Section 3-5 on page 3-11) Changing parametersALARM/CONTROL (see Section 3-6 on page 3-16) Set alarms or ON/OFF controllersCALIBRATION (see Section 4-2 on page 4-1) Gas calibration/pressure inputsHOLD (see Section 4-3 on page 4-5) Retain last output valueDIAGNOSTICS (see Section 4-4 on page 4-8) Electronics checks

The Model 7003M Percent Oxygen Analyzeris housed in a NEMA 4X (CSA enclosure 4),corrosion resistant housing suitable for panel,pipe or wall mounting.

The analyzer has a microprocessor controlledkeyboard for operation. Signals from theremote oxygen and temperature sensors areprocessed to compute real time oxygenconcentration corrected for temperature,constant pressure differences and residualsensor current. The oxygen concentration iscompared with user-set alarm parameters,and also generates an isolated 4 to 20 or 0 to20mA signal. Data is stored in a memorycircuit that retains the data in case power isremoved.

The analyzer is shipped from the factoryconfigured for operation on either 115 VAC or230 VAC, 50/60 Hz as specified by thecustomer when ordered.

1-2 PRINCIPLE OF MEASUREMENT

Measurement is based on the electro-chemical reaction between oxygen and thesensor cathode which produces a low levelelectrical current. The sensor signal isproportional to the partial pressure of oxygenpresent at the membrane. This signal and athermistor signal are received by the analyzerand processed by the electronics to output acalibrated oxygen signal that is compensatedfor temperature.

1-3 SENSORS

Rosemount Analytical offers rechargeable anddisposable oxygen sensors which can beused with the Model 7003M. These sensorsare supplied in kits: Submersion, in-line flow,fast response, and a cell separation kit.Sensors are available constructed ofpolypropylene or Ryton. See Section 7-4REPLACEMENT PARTS - SENSORS onpage 7-3, for additional information.


1-2 Description and Specifications Rosemount Analytical Inc. A Division of Emerson Process Management

Model 7003M

1-4 CONDITIONS AFFECTING MEASUREMENT

Oxygen measurement is affected by thefollowing:

• Composition of the sampled gas

• Sample and calibration gas pressures

• Environment of sensor, cable andanalyzer

Each must be considered when calibratingand operating the analyzer to obtain accuratemeasurements.

a. Gas Composition

Any substance in the sample thatsignificantly interferes or "poisons" thesensor oxygen reading should beremoved by a chemical and/ormechanical sample handling system (seeSection 5-2 on page 5-1). If ambient air isnot used as the span gas, thecomposition of calibration gases shouldalso be representative of the sample.

The sample and calibration gases mustmeet certain specifications (seeSpecifications in Preface) to ensureaccurate measurement. Physicalparameters that affect measurementinclude:

• Pressure

• Humidity

• Temperature

• Gas composition

Also refer to Section 5-2 on page 5-1 foradditional information about how gasconditions affect the oxygenmeasurement.

b. Sample and Cal Gas Pressures

The sample and calibration gases may beat different pressures as long as thepressure of each remains constant. Anyvariation in the pressure of either gas willresult in an incorrect output reading of thesame proportion.

Two methods of sample calibration arerecommended:

1. Calibrate at the sample pressure, or

2. Calibrated at a different pressure, andenter the two pressure in the analyzer(Section 4-2c on page 4-4)

Refer to Section 5-2 on page 5-1 for amore detailed discussion of therelationship between gas pressures andapparent oxygen concentration.

c. Environmental Factors

If radio frequency interference (RFI)normally occurs in the operatingenvironment, the sensor cable should beelectrically shielded during installation.

Suppressed RangesWhen setting the Model 7003M to asuppressed output range (15 to 25%, etc.),note that the absolute accuracy, drift, andnoise of the oxygen measurement will remainthe same for all ranges (see Specifications inPreface).

ALARM ModeALARM Mode is not self-resetting. Operatormust press ACK to bring relays back to theirno-alarm state. Used when immediateoperator action is required.

NOTE:Operator Can Bypass Alarm Relays

When relays are set to ALARM Mode (Sec-tion 3-6a on page 3-16) and an alarm con-dition has occurred, pressing the ACK keywill turn off the relay switch, whether theoxygen level is out of range or not. If youdo not want an operator to be able to by-pass the relay switches in this way, set theinstrument to ON/OFF -CONTROL Mode.

SECTION 3OPERATION

3-1 OVERVIEW

It is recommended that the operator read theentire manual through before first operatingthe instrument.

The operator can generally operate the Model7003M using the flow chart in Figure 3-2 onpage 3-2 after the display symbols and modesof operation are understood.

3-2 KEYPAD OPERATION

During each particular keystroke sequence,the analyzer will recognize only certain keys.If an unrecognized key is pressed, theinstrument will either not respond or willdisplay "SrY" ("Sorry") and return to RUNMode.

Generally, to escape from any routine, pressENTER repeatedly until the instrument returnsto the RUN Mode and the oxygenconcentration is displayed.

Changing Parameters With The KeypadAll operation parameters are set with thekeypad. When the instrument is waiting foroperator input, the display will flash a digit. Atthis point, if the number itself can be changed,the operator can generally increase thenumber (UP arrow) or decrease it (DOWNarrow) at this time. An exception is when theoperator is restricted to pre-selected choices(e.g., output current ranges, see Section 3-5bon page 3-13).

When changing a value, an arrow key can bepressed for a moment, and the display willchange by one digit. If it is held down, thedisplay will change, slowly at first, thenrapidly.

If the display has a digit flashing and will notchange, check the range of that parameter.For example, an alarm setpoint cannot be sethigher than 25%.

When the number desired is displayed, pressENTER. The Model 7003M will accept thatnumber and continue with the next step of thatroutine.

d. Automatic Return to RUN Mode

If no keys are pressed for five minutes,the instrument will automatically return tothe RUN Mode, except when in ZeroOffset, HOLD, or DIAGNOSTICS Modes.

CAUTION

OXYGEN WILL NOT BE MONITOREDThe instrument will remain in HOLD or DI-AGNOSTICS Modes until the operator re-turns it to the RUN Mode or otheroperation.

e. Preventing Unauthorized Access

The Model 7003M is equipped with asecurity feature to prevent unauthorizedtampering with the instrument settings.The instrument is shipped from the factorywith the security feature disabled. It canbe enabled or disabled at any time.

Security access is not required to:

• Display sensor data• Acknowledge alarms• Reveal security code

Security access is required to:

• Calibrate with span gas• Access options and diagnostics• Change operation parameters• Enable or disable alarms and

ON/OFF-Control• Disable or change the security code

After the security code is entered, theoperator can change any instrumentsetting and can go back and forth to theRUN Mode without having to enter thecode again.

If security is enabled, and the instrumentis left in the RUN Mode for five minutes,security will automatically be re-activated.Within this five minute period, anyone canaccess the functions without re-enteringthe security code.

f. Sensor Equilibrium

When a new sensor is installed, power upthe instrument and let the sensor stabilizefor about 5 hours before calibrating it.

If the oxygen sensor is calibrated at arelatively high oxygen concentration, suchas with ambient air (typically 20.95%) andthen is exposed to a low oxygen level, alonger equilibrium time period may berequired for the sensor to equilibrate.This time period depends on themonitoring concentration level and howlong the sensor was operated at thehigher level.



Model 7003M

3-3 START-UP

Before proceeding, the operator should befamiliar with the keypad and indicators(Section 3-2 on page 3-1).

Operational checks and adjustments are notnormally required, provided that the sensor,inter-connection cable and analyzer havebeen properly installed. The analyzercontinually performs self-checking routinesduring operation.

Calibration with ambient air is recommendedafter start-up and at regular intervals (seeSection 4-2 on page 4-1)

The following sections provide instructions forinitial start-up and subsequent standardizationof the analyzer.

a. Initial Power-Up

1. Ensure that the proper sensor andsensor cable are connected to theanalyzer.

2. Apply power to the analyzer.

The following internal tests areperformed:

RAM Read/write test

ROM "Checksum" testEEPROM Read/write test

3. If an error code flashes, refer to theerror code lists in Table 3-10 throughTable 3-13. Press ACK to continuewith the startup procedure.

After internal tests are passed, thesoftware version is displayed for afew seconds, and the analyzer goesdirectly into RUN mode. "RUN" isbriefly displayed, then currentoxygen level.

Error codes E-0 (power failure) andE-5 (not calibrated) typically occurupon power-up.

4. Monitor the oxygen output or displayuntil the level stabilizes (typically 5hours). The alarms and currentoutput levels can be set immediately ifdesired.

5. Once the sensor has stabilized, theanalyzer is operational and is readyfor subsequent operations. Refer toTable 3-14 below for the defaultsettings present upon power-up.

d. Zero Offset Adjustment

Following the last procedure, the currentzero offset value will be flashing.

NOTEWhen flowing zero gas over the sen-sor, ensure that there are no leaks andthe gas actually has zero oxygen con-centration. Otherwise, significant er-rors will result. Zero offset adjustmentis generally not required. Errors aremore often due to incorrect zero gasoxygen concentration than residualcurrent of the oxygen sensor.

The zero offset adjustment allows theoperator to compensate for any residualsensor current. Adjustment range is 0-5%equivalent oxygen.

Sensor Current = Current fromOxygen + Residual Current

NOTEAdjusting the zero offset affects theoutput of the Model 7003M. Therefore,if the zero offset is changed, the sys-tem must be re-calibrated with spangas.

a. Relay Configured as Alarm

Relays are configured as alarms (ALARMMode) when immediate operator action isrequired.

When alarms are selected, "A-1" and "A-2" are displayed in the ALARM mode set-up procedure.

When an alarm condition occurs, thecaret blinks, the relay activates, and thedisplay flashes. Press the ACK key toacknowledge the alarm, de-energize therelay coil and stop the alarm actions.

b. Relay Configured as ON/OFF-Controller

Relays are configured as ON/OFF-Controllers (ON/OFF-Controller mode)when a non-critical, non-hazardousautomated action is desired, or when it isimportant that the relay output not bebypassed by the operator.

When ON/OFF-Controllers are selected,"C-1" and/or "C-2" is displayed in theALARM mode set-up procedure.

When an ON/OFF-Controller alarmcondition occurs, Alarm 1 or 2 caret blinksand the relay coil is energized. However,the display does not flash, and the ACKkey is inactive. Alarm conditions areautomatically reset when the sensorindicates that an alarm condition nolonger exists.

b. Test Current Output

The current output can be tested(increased or decreased using theARROW keys) and the actual output willchange. When the instrument returns tothe RUN mode, the output will return tothe previous value.

1. Press DISPLAY until the minus sign (-) is displayed on left.

2. Use the ARROW keys to increase ordecrease the current output.

c. Linearizing Current Output

For some samples, current output doesnot track the oxygen reading displayed.The operator can linearize output andstore the compensating second-orderpolynomials in EEPROM. This data willremain and function there as long as theEEPROM is not erased. However, if a"cold boot" is performed, the operatormust repeat this linearization routine.


June 2002


Model 7003M

To determine if current outputlinearization is necessary, do thefollowing:

1. Connect a separate current meter tothe output terminals (any device thatwill display an accurate currentmeasurement such as a computerinput will suffice).

NOTEDo not simply connect a currentmeasurement meter in parallel with theusual load because this will lead to in-correct readings.

2. Place the instrument in DIAGNOSTICmode by pressing the UP and DOWNARROWS, followed by the DISPLAYand ACK keys. The display will showconsecutively:

tSt, d-3, d-4, and oxygen inputvoltage

3. Press the DISPLAY key until theminus sign and a number aredisplayed. This reading is the currentoutput (in milliamps) as determined bythe Model 7003M.

4. Use the UP and DOWN ARROWkeys to increase the display reading,and occasionally, compare the currentdisplayed on both meters (theinstrument display and the separatemeter).

5. If the two readings are too disparate(different applications require lesseror greater tolerance), do the following3-point calibration to linearize thecurrent output:

6. Use the UP and DOWN ARROWkeys to set the current output to avalue halfway up its range. Theoperator may prefer to set it at acritical measurement point.

7. Press the CAL key. The instrumentwill flash CCA, illuminate the threeright-hand carets, and continuedisplaying the current output.

8. Use the UP and DOWN ARROWkeys to adjust the actual currentoutput (as noted on the separatemeter) to the correct amount. Notethat the instrument display does notchange.

9. Press ENTER, the instrumentdisplays diA, returns to theDIAGNOSTIC mode, and continues todisplay the current output.

10. Use the UP and DOWN ARROWkeys to adjust the current output to alower value, representing the lowrange (the operator may prefer to use4 mA to represent 0% oxygen).

11. Press CAL (the instrument displaysCCL for lower current output setting),and repeat steps 3 and 4 of thisprocedure.

12. Use the UP and DOWN ARROWkeys to adjust the current output to avalue higher than the initial calibrationvalue (step 1 of this procedure),representing the higher range (theoperator may prefer to set it at16.72mA to represent 20.9% oxygen.

13. Press CAL (the instrument displaysCCH for high current output setting),and repeat steps 3 and 4 of thisprocedure.

To return to the RUN mode, pressENTER twice.

At any time during this procedure, theoperator may press the ACK key to resetall calibration coefficients to defaultvalues. Pressing DISPLAY at any timeduring this procedure will cause theinstrument to display for a moment therelevant calibration efficient.

The operator may escape the currentCALIBRATION and DIAGNOSTIC modealtogether by pressing ENTER twice.Note, all coefficients will return to thedefault values, and the current calibrationprocedure must be started over tolinearize current output.



Model 7003M

NOTEThe low calibration point must be be-tween the initial calibration point (step1 of previous procedure) and zero, andthe high calibration point must be be-tween the initial calibration point and20mA.

If the third point calibrated (step 8,previous procedure) is actually an-other low range (between the initialcalibration point and CCL) it will over-ride the original CCL but won't affectthe initial calibration.

NOTEThe current output linearizing proce-dure uses second order polynomials toadjust the output linearity. The correc-tion effect is maximized at the calibra-tion point, and is smoothly diminishedtowards the endpoints.

d. Test Alarm Relays

1. Disconnect any alarm or ON/OFF-Control devices that are connected tothe analyzer, before testing.

NOTEWhen alarms are tested manually, anyalarm or ON/OFF-Control devices con-nected to the relays will respond asthey would in an alarm condition. Thealarm devices may have to be discon-nected from the relays for this test.

2. Toggle the relays ON and OFF usingthe ALARM 1 and ALARM 2 keys.

A-1 ON or A-2 OFF is displayed.The alarm contacts can be heardopening and closing.

3. Connect any alarm or ON/OFF-Control devices that weredisconnected in step 1.

4. Press ENTER to exit theDIAGNOSTICS mode.

"Hld" flashes alternately with the lastoxygen reading and the analyzerreturns to HOLD mode.

5. Press ENTER again to return to RUNmode.

Rosemount Analytical Inc. A Division of Emerson Process Management Theory 5-1

Model 7003M

SECTION 5 THEORY

5-1 PRINCIPLES OF OPERATION

The Model 7003M Percent Oxygen Analyzerconsists of an amperometric sensor andanalyzer interconnected by a multi-conductorshielded cable. The sensor responds to thepartial pressure of oxygen and produces acurrent signal. The analyzer amplifies andprocesses the signal, providing readout inpercent oxygen and current output.

a. Electrochemical Theory

With the sensor placed in the sample gas,a voltage is applied across the cathodeand anode. Sample gas diffuses throughthe membrane and is reduced at thecathode resulting in a current proportionalto the partial pressure of oxygen in thesample.

When no oxygen is present, a smallresidual sensor current, which can beoffset during instrument setup.

5-2 EFFECTS OF SAMPLE CONDITIONS

a. Barometric Pressure

If ambient air is used to calibrate thesensor, a change in barometric pressurecan be a significant factor. At 76 cm Hg,the partial pressure of oxygen is 15.9 cmHg (20.9% of 76 cm Hg). As atmosphericpressure deviates from 76 cm Hg, thepartial pressure of oxygen will varyproportionally. The highest partialpressure that can be read by the Model7003M is 19 cm Hg (25% oxygen at 76cm Hg).

b. Humidity

If calibrating with humid ambient air, theeffect of the partial pressure due to watervapor content should be taken intoconsideration. High humidity has theeffect of reducing the partial pressure of

oxygen without affecting the totalbarometric pressure.

This relationship can be expressed as :

P atm = Po2 + PH20 = P other,

where:

P atm = total barometric pressure,

Po2 = partial pressure of oxygen,

PH20 = partial pressure of watervapor,

P other = partial pressure of allgases other than oxygen and watervapor

c. Sample Temperature

The rate of oxygen diffusion through thesensor membrane varies withtemperature, with a coefficient of about+3% °C (5% °F), causing a correspondingchange in sensor current. The instrumentcontinuously monitors temperature with athermistor in the sensor body, andcompensates the output for both sampletemperature and membrane permeability.

Because of a slight time lag in theresponse of the temperature sensor, arapid temperature change will cause atemporary change in apparent oxygenlevel, such as might be encountered if thesensor is suddenly exposed to directsunlight from a shadow.

Extended use of the sensor at lowtemperatures will shorten the life of thesensor. As the sensor reaches the end ofits useful life, distinct step changes in theoxygen reading will be evident as theoxygen level changes.


5-2 Routine Servicing and Troubleshooting Rosemount Analytical Inc. A Division of Emerson Process Management

Model 7003M

d. Interfering Gases

Gases that are reduced or oxidized in therange of 0.5 to 0.8VDC contribute tosensor current and can cause a readouterror. Only a few gases have thischaracteristic. Common gases thatshould be avoided include SO2, Cl2, andoxides of nitrogen (NOX). Low-levelconcentrations of hydrogen sulfide tend tocontaminate the sensor, but may notseriously affect oxygen measurement.

If you suspect that any streamcomponents are affecting the operation ofthe sensor, contact Rosemount AnalyticalTechnical Services.

If contaminated, the rechargeable sensormust be rejuvenated and the disposablesensor must be replaced. Refer to theinstructions supplied with the sensor.

5-3 CIRCUIT DESCRIPTIONS

a. Signal Board

The Signal Board is configured to matchthe type of sensor ordered with theanalyzer. If the type of sensor ischanged, or the Signal Board is repairedor replaced, verify the rocker switchposition (SW1):

Rechargeable Sensor: Close positions1,4, and 5

Disposable Sensor: Close positions 2,4,and 6

b. Power Supply Board

The Power Supply Board provides:

• ±12V (non-isolated) for analogsignaling function

• +5V (non-isolated) formicroprocessor and associatedlogic

• +24V (non-isolated) for theisolated current function

• +5V (isolated) for other functionsfor that circuit

There are isolated and non-isolatedgrounds on the Power Supply Board.TP1 is the non-isolated ground andshould be used with TP6 and TP7.

c. Microprocessor Board

The Microprocessor Board is thefunctional center of the instrument. Withthe exception of the program chip, nouser serviceable functions are on thisassembly. If the Microprocessor Board isto be repaired or replaced, note thepositions of the configuration jumpers forsetting jumpers on replacement board.

An instrument timer circuit monitorsinstrument power for a power failure,power surge or other outside conditioninterfering with the microprocessoroperation. When conditions return tonormal, the circuit will attempt a systemrestart. If the microprocessor is stillcapable of operating, both alarm relayswill be put into alarm condition, the screenwill clear, and the output current will dropto 0 mA. Then the instrument will gothrough a normal power-up routine andwill eventually return to routine operationwith alarms and output restored to theirnormal conditions. The appropriate errorcode (E-0, etc.) will be displayed until theACK button is pressed.

d. Alarm Circuits

Each alarm activation setpoint is designedto be at a different level from thedeactivation setpoint:

• To prevent relay contacts fromchattering if the oxygen level staysaround the setpoint.

• To indicate to the microprocessorwhether alarm is HIGH or LOW.

• To allow for a time lag between thetime the alarm is activated and thetime it is deactivated for ON/OFF-Control purposes.

Model 7003M

Error code E-0 displayedPossible causePower interruption, power surge or otheroutside interference has occurred

Corrective ActionPress ACK. If this symptom occursfrequently, surge-protection isrecommended.

Will not read low levels of oxygenPossible causeAmbient air leaking into system

Check/TestIncrease sample flow rate, block offflow of gas in and out of flowchamber, and not analyzer response

Corrective ActionIf signal increases with test, isolateand seal leak.If signal does not increase, replace orrecharge sensor.

Sudden change in output for no ap-parent reasonPossible causeSensor subjected to sudden change inconditions, as when a shadow movesand exposes the sensor to an increasein temperature

Corrective ActionLocate sensor in an area shaded fromsunlight and away from cold or warmdrafts.

Resolution degrading with timePossible causeSensor exposed to low temperatures.

Check/TestPer Section 4-4b on page 4-8, checkcurrent output of sensor.

If the sensor is degrading, the signal willchange in steps as the oxygen levelchanges instead of changingcontinuously.

Corrective ActionRelocate sensor or replace morefrequently.

SECTION 7REPLACEMENT PARTS

7-1 CIRCUIT BOARD REPLACEMENT POLICY

In most situations involving a malfunction of acircuit board, it is more practical to replace theboard than to attempt isolation andreplacement of an individual component. Asstandard policy, rebuilt boards are availableon an exchange basis.

Because of the exchange policy coveringcircuit boards, the following sections onreplacement parts do not include individual,circuit board mounted components. Ifcircumstances necessitate replacement of anindividual component, which can be identifiedby inspection or from the schematic diagrams,obtain the replacement component from alocal source of supply.
