3.5 Measure menu

The flow chart (Fig 3 below) depicts the instrument measurement options available. Theflow lines are keyed to specific instrument actions.

Your instrument is pre-set with certain default values to anticipate your measurementconditions, such as measurement display units, thermal cutoff temperature, etc. Youmay, however, change these using the Instrument Modify Options Menus described in“Options set up” on page 17.

3.6 Measurement displays

Switching on the indicating instrument first shows the software version and date on theLCD, and then switches to a Configuration Display showing the gas being measured,the purge gas required for the sensor, and the membrane model number for this sensor.In the example shown in Fig 4 the display shows the gas being measured (g) as CO2, thepurge gas (p) as being N2 and the sensor membrane (m) as being model number 29561.

The configuration screen appears for the duration of the measurement cycle (usually 15to 25 seconds), before switching to a continuous gas and temperature MeasurementDisplay.

There will be a delay between successive display updates depending on the length of thepurge/measurement cycle. Depending on the Number of Ranges configured for theinstrument (see “Display units” on page 18), the display resolution changes automaticallyto reflect gas and temperature measurement value changes. To make changes to thedisplayed units of measurement and display resolution, refer to “Display units” onpage 18.

Press the ESC key to exit from the measurement display and move to the Main Menu toaccess additional menus (Measure, Options and Calibrate).

3.7 Measurement hold switch (CO2 and N2 systems only)

Interruptions in the sample flow can cause temporary variations in measurements of CO2or N2 gas concentrations. For this reason, the instrument provides a Hold capability toexclude these measurements from the statistics. To use this capability, you must providean external switch (for example, on a filling machine) that is open while the sample isflowing and closed during the flow interruption. Wire this switch as described in “Holdswitch wiring identification” on page 59.

When the switch is closed, indicating a Hold condition, the instrument holds the last gasmeasurement values on all outputs, though temperature changes continue to occur,flashes a HOLD message between LCD updates, and shows a Hld code in the LCDbottom line at the right of the temperature measurement

Once the switch is reopened (typically, with the restart of sample flow) the instrument willstart to display the new measurement values. However, these values should not beconsidered accurate until after one to four additional measurement cycles have beenperformed (15-60 seconds). You can specify the number of additional cycles using theHold Recovery option in the Options menu, see “Hold recovery (CO2 and N2 systemsonly)” on page 22.

3.8 Accessing measurements from the PC

If you have installed the Data Acquisition Software (as described in “Data acquisitionsoftware” on page 39), you can use this program to download measurement data to yourPC.

a ) Menu overview

The program's main menus appear as follows:

• File includes typical Windows file management and printing functions.• Terminal commences and ends the data acquisition process.• Export sends the information to the Windows Clipboard, for inclusion in other

Windows programs.• Configuration lets you customize the program for your application's

requirements.• About gives information about the current acquisition software version number.

b ) Acquiring data

With the instrument connected to your PC, and the sensor placed in a sample, youshould be able to conduct an initial data acquisition test.

First, make sure the program knows which COM port is used by your PC by choosingCommunications from the Configuration menu. Ensure the correct COM port ischecked (see Fig 6).

The number of samples in the buffer continues to rise until you choose End from theTerminal menu, or when the limit of 2000 samples is reached.

c ) Printing, copying and saving data

The File, Print command places your list of values into a pre-formatted tabular template,and sends it to your printer. The program asks you to enter Title and Author informationas illustrated in Fig 10. The operating system automatically sets the Date.

The resulting printed list includes the Title, Author and Date information on each page.

To save this list as a text (.txt) file, capable of being recalled by the MOCA3610 programor imported as a file into other Windows programs, choose File, Save as. A dialog boxappears, with a space to fill in with an eight-letter name. (The program automaticallyattaches a .txt suffix to these files.)

If you have saved previous files, a grayed-out list of these names appears as well.Typical to Windows programs, Directories and Drives boxes can be used to locateother places to save the file. You may also type the drive and directory yourself whensaving the file.

To copy this list to the Windows Clipboard, so that this information can be pasted into aspreadsheet, word processor or any other kind of Windows program that accepts tabulartext information, choose Export, To Clipboard.

3.9 Shutting down the system

Since the indicating instrument has a non-volatile memory, important parameters remainmemorized even when the instrument power is off.

During a short shutdown period (such as weekends), the sensor can be left in line, withthe instrument operating and the purge gas supplied.

Note :If the model 32605 Purge Backup Unit is installed as described in “Model 32605 purge backup unit” on page 39, the instrument can also be turned off.

If the inactive period is likely to last for a period of longer than 2 days, then to avoid anydamage to the sensor, remove it from the line and dry it off before storing. Refer to theassociated TC Sensors - Maintenance & Installation Manual, provided with yourinstrument, for full instructions on this process.

4.7 Rolling average

The rolling average feature causes the instrument to average measurements oversuccessive measurement cycles. It suppresses sharp peaks and troughs, while retainingreasonably fast response to real concentration changes.

Choose ROLLING AVERAGE from the MODIFY OPTIONS menu. Then selectDISABLED if rolling averages are not required, or select the number of successivemeasurement cycles (each being approximately 22 seconds), over which the averagewill be taken (3,5,7 or 9).

4.8 Language

The instrument can display its menus in English, French, Japanese, Spanish, German,or Italian although the units of measurement remain the same (i.e. parts per million is stillexpressed as ppm regardless of language).

Choose LANGUAGE from the MODIFY OPTIONS menu and select your preference.

4.9 Hold recovery (CO2 and N2 systems only)

This option allows you to choose a longer or shorter recovery time after a Hold conditionhas ended.

Choose HOLD RECOVERY from the MODIFY OPTIONS menu. You are given a choiceof 1, 2, 3 or 4 cycles before normal measurement resumes, each cycle beingapproximately 15 seconds in length. Highlight the desired recovery period, and thenpress ENTER.

4.10 Offset

While Orbisphere analyzers are accurate to within 0.006 V/V of CO2, 0.01 cc/kg of H2, or0.3 ppm of N2, you may wish to apply a specific offset value to the displayed gasmeasurement.

If, for example, 0.1 V/V should be subtracted from CO2 measurements, choose OFFSETfrom the MODIFY OPTIONS menu to bring up the data entry screen.

The measurement display, recorder analog output, and RS-232 output of gasconcentration reflect this offset value. The RS-232 output also lists the offset value in aseparate column.

For this example, you would want a negative offset sohighlight NEG. and press ENTER.

Enter the value to be subtracted and press ENTER.

Use the UP/DOWN ARROWS to move the decimal place tothe correct position in the displayed value, and pressENTER to confirm and save.

4.11 Corrections

Note :This option is reserved for qualified Orbisphere Service Representatives only. As such, if you feel that corrections are required, please contact your local Orbisphere Service Representative to perform this operation for you.

a ) Temperature correction

If the sample temperature varies during the measurement cycle, the temperature changeis translated as an interference signal on the sensor measurements. This option reducesthe influence of temperature variation on the sensor.

When the process temperature is steady or changes very slowly, this correction is notnecessary, thus it should be disabled.

Choose CORRECTIONS in the MODIFY OPTIONS menu followed by TEMPCORRECTION. Select ENABLED to apply a temperature correction to gasmeasurements, or DISABLED if no correction is required.

b ) Humidity correction

This routine only concerns measurements made in 100% humid gases or in traces ofdissolved gas in water.

Choose CORRECTIONS from the MODIFY OPTIONS menu and HUMIDITY. This menuprovides a choice of DISABLED, ENABLED and CALIBRATE.

If you are making trace measurements in dry, or less than 100% saturated gases, thenthe built-in humidity correction would be inappropriate, and should be DISABLED.

If you are measuring gases in the presence of humidity, however, the contribution fromhumidity to the measured thermal conductivity is calculated from built-in formulae, andsubtracted from the net measured result.

Choose ENABLED to apply the correction, using previously stored humidity parameters,for the amplitude and temperature coefficient of the correction. When you enablehumidity correction, this correction is applied to each sensor reading. The amount ofcorrection is listed in the RS-232 diagnostic output (see “Serial output” on page 21).

Choose CALIBRATE from the menu to begin calibration of the humidity effect andperform a recalculation of the amplitude parameter. The temperature coefficient is set bydefault, and cannot be changed.

The next screen then directs you to expose the sensor to a humid gas sample. You mustexpose the sensor to a sample having a known humidity, and no measured or interferinggas. Either the sensor can be exposed to a sample of humid purge gas or it can bedirectly immersed in water and purge gas.

In the case of measurements in humid air, using a dry air purge, the water can be simplyaerated, and it suffices to immerse the sensor in water from a tap.

It is permitted, however, to have the purge gas present in the sample since this gas doesnot interfere. You can either use purge gas saturated with water, or water saturated withthe purge gas.

The act of saturating water with the purge gas (see Fig 13) eliminates all other potentiallyinterfering gases, given enough time. If the water volume is restricted to a few tens ofmilliliters, about 15 minutes is adequate time to ensure complete purging of interferinggases and temperature equilibration.

Watch the signal (Slope value displayed on screen) change until it becomes stable.When the signal is stable, press ENTER to store the new humidity correction.

As an alternative to exposing the sensor to humid gas, expose the sensor to a watersample that is saturated with the purge gas. In this calibration, the purge gas passesthrough water-saturated material (a porous piece of paper) that is in the flow chamber(see Fig 14).

To perform this calibration, wet a piece of paper until it is saturated with water, but notdripping. Use a porous and durable type of paper, such as a piece of coffee filter papercut to fit into the flow chamber. Then, disconnect the flow chamber from the sensor, placethis paper into the flow chamber (as illustrated in Fig 14) and reconnect the sensor.

Next, start the purge gas into the flow chamber, running the gas at a flow rate of aboutone bubble per second into a beaker of water.

Run the gas through the saturated paper, for about 5 minutes, until the signal becomesstable. When the signal is stable, stop the flow of gas to the Flow Chamber. Watch thesignal change again until it is stable at a new level. When no further change occurs,press ENTER to store the new humidity correction.

4.12 Liquid/Gas coefficient

If the liquid sample flow rate is below the minimum required, then the measurement willbe lower than the actual value. If the actual measurement value is known by some othermeasurement system, then a value can be entered here which will be used to computethe correct actual value.

The measured value will be multiplied by the coefficient value entered here to give thecorrect measured value. By default, this value is set to 1.

4.13 Membrane selection

The H2 sensor can be fitted with different membranes, each having individual sensitivityand flow requirements. To select the correct membrane, choose MEMBRANE from theMODIFY OPTIONS menu then choose the membrane model number from the listdisplayed.

Once you select any membrane (even if you reselect the same membrane and pressENTER), you must re-calibrate the sensor, as described in “Calibrations” on page 27. Inaddition, you must re-calibrate any corrections you may be using, as described in“Corrections” on page 23.

Note :For detailed specifications regarding sensors and membranes, please refer to the accompanying TC Sensors - Maintenance & Installation Manual.

Enter the value of the liquid/gas coefficient.

5 Calibrations

5.1 Calibrate menu

Note :Dependant on your instrument configuration, some of the options described in this section may not be available on your system.

As delivered, 3610 systems are pre-calibrated. Check your sensor in measurementmode (see “Operating information” on page 9) before attempting to calibrate.

The flow chart in Fig 15 illustrates the sensor calibration menus.

Note :When you select the Calibration menu, the instrument discontinues all measurement operations.

All of the menus require user input of one form or another. This is carried out using thefour function keys on the Instrument Panel (see “Instrument controls” on page 9). You

should ensure you are familiar with the use of these keys in entering and modifyingnumeric fields (see “Entering numerical values” on page 10), before accessing thesemenus.

Note :When using non-Orbisphere instruments during calibration processes (e.g. pressure gauges), their accuracy should be 10 times more precise than Orbisphere instruments.

5.2 Barometric pressure sensor calibration

You can verify or calibrate the instrument's internal barometric pressure sensor againstyour local atmospheric pressure.

Select CALIBRATE from the main menu followed by BAROM PRESSURE.

5.3 External pressure sensor calibration

The instrument can be fitted with a model 28117 external pressure sensor, capable ofmeasuring up to 3.5 bar (50 psi). An accurate pressure gauge is required to calibrate thissensor.

Select CALIBRATE from the main menu followed by EXTERN. PRESSURE.

There are two methods of calibrating this sensor:

• ONE POINT permits you to calibrate at one pressure value• TWO POINT requires that you calibrate against high and low pressure values

(generally required only for high-pressure applications)

The instrument first displays the current barometricpressure reading. Press ESC if this agrees with yourcurrent atmospheric pressure, or ENTER to modify andbring up the next screen.

Enter the new value and press ENTER to return to theprevious BAROM. PRESSURE display, followed by ESCto accept the value.

The instrument first displays its current external pressuresensor measurement. If this agrees with the pressurecurrently applied to the external pressure sensor, thenpress ESC. If this measurement does not agree, and youwish to re-calibrate, press ENTER to display the menu forselection of pressure measurement units. Choose thedesired units to bring up the calibration Method menu.

Choosing ONE POINT allows you to enter the absolute(gauge plus atmospheric) pressure currently applied tothe external pressure sensor. Press ENTER when thevalue has been entered.

Use the UP/DOWN ARROWS to move the decimal placeto the correct position in the displayed value, and pressENTER to confirm. The instrument then calibrates thesensor and returns to the external pressure display.

The TWO POINT calibration requires that you apply and enter a LOW POINT and aHIGH POINT pressure value. The menus are similar to the ONE POINT menu describedabove.

Enter the atmospheric pressure as the low point value. Then, adjust the forcing gaspressure to between 2.5 and 3 bar (absolute) for the high point. Enter the absolutepressure (gauge plus atmospheric pressure) of the forcing gas for the high point.

After you enter the second value, the instrument calibrates the sensor and returns to theexternal pressure display.

5.4 TC sensor calibration

When calibrating, the TC sensor is exposed to either:

1) A source of 100% pure CO2, H2, or N2 gas at a known elevated pressure (Partial Pressure)

2) A known concentration of CO2, H2, or N2 gas at a known pressure (Fraction)3) A known concentration of dissolved CO2, H2, or N2 (Dissolved)

The Partial Pressure method is generally recommended only when measuring at higherline pressures, and requires a precise in-line pressure gauge to perform.

For calibration in a gaseous sample, the advantage of the Fraction method is that it isindependent of the precision of other devices, and is fairly easy and quick to perform.

WARNINGHandle H2 gas with great care ! It is extremely flammable and explosive.

TC sensor calibration may be performed either in-line, with the sensor left in its mounting(such as a sensor socket or flow chamber), or off-line with the sensor removed, using aseparate flow chamber.

a ) In-Line calibration

Performing an in-line sensor calibration with a gaseous or liquid sample of known gasconcentration can be convenient, since you can leave the sensor in its mounting. Yousimply introduce the reference gas or liquid to the sensor, and enter the expected valuesvia the menus.

For in-line calibration, first you must shut off the sample flow. Then, connect a source ofthe gaseous or liquid reference sample to the sensor in its mounting (sensor socket orflow chamber), and purge all existing gas or liquid out of the system. If you are calibratingin-line, using a gaseous sample, in a model 32001 flow chamber, connect the calibrationgas source to the flow chamber's outer port (as illustrated in Fig 16).

Fig 16 shows how to introduce both calibration gas and normal sample media to the flowchamber, if required. A and B represent 3-way valves. Calibration gas is sent in throughthe sample out port and waste gas is sent out through the sample in port, as shown (left).In normal measurement operation (right), the calibration gas inlets and outlets are shutoff

Note :When your system returns to measurement immediately after a successful in-line calibration, the displayed value may appear slightly lower than expected until two or three measurement cycles have elapsed. This is the sensor's normal response to switching from Calibration to Measurement mode.

b ) Off-line calibration

First shut off the sample flow. Then, extract the sensor from its socket or mounting andclose off the socket with the stainless steel plug provided. (If you are using a model32003 ProAcc insertion/extraction valve, the sample is sealed off automatically as thesensor is withdrawn.) If you are using a flow chamber, shut off the sample flow and thenextract the sensor from the flow chamber. Also, if you are using an external temperaturesensor, disconnect it from the sensor.

Make sure that the grill in the front of the sensor is clean and dry. Insert the sensor in themodel 32001 flow chamber, and tighten with its collar. Connect the gaseous or liquidreference sample to the flow chamber's central sample entry port and purge all air andwater out of the system.

The exit from the flow chamber should be unobstructed, thus making the pressure incontact with the sensor equilibrated with that of the atmosphere. If the exit from the flowchamber is completely free, the gas pressure in contact with the sensor will be that of theatmosphere.

Alternatively, adjust a needle valve on the exit from the calibration unit to raise theapplied pressure to any other desired calibration pressure. This has the advantage thatyou can simulate more closely the actual gas pressure in the sample, so raising theprecision of later measurements - but it has the disadvantage that an accurate pressuregauge must be available.

c ) Partial pressure calibration

With this procedure, you must expose the sensor to a known pressure of pure CO2, H2or N2 gas, in the range of 1 to 5 bar absolute.

The procedure requires a source of pure gas (regulated by a pressure valve) connectedto the central entry port of the flow chamber, an accurate pressure gauge at the exit ofthe flow chamber, a needle valve to control the gas flow on exit, and a beaker of water tomonitor the gas flow (as illustrated in Fig 17).

To carry out the calibration, open the valve on the gas cylinder. Adjust the needle valveuntil gas is flowing through the chamber at a rate of about 1 bubble per second indicatedby the beaker of water. Adjust both the valve on the gas cylinder and the needle valve

until your desired calibration pressure is indicated on the accurate pressure gauge at theexit to the flow chamber and the flow rate is approximately 1 bubble per second.

To expose the sensor to the gas and to stabilize the reading, operate in MeasurementMode for about 30 minutes. After this time, press ESC and select CALIBRATE from themain menu, followed by SENSOR TC and PARTIAL PRESSURE. Select your preferredunit of measurement from the PART PRESS CAL menu, to bring up the menu forspecifying the gas pressure.

Note :If this is the first calibration then the message indicates a percentage of the expected value, rather than the last calibration.

Fig 17 : Partial Pressure Calibration Diagram

Enter the absolute gas pressure, taken from the pressuregauge at the exit of the flow chamber. Press ENTERwhen the value has been entered.

Use the UP/DOWN ARROWS to move the decimal placeto the correct position in the displayed value, and pressENTER to confirm and start the calibration process.

The calibrating... please wait message appears for afew seconds, and then the instrument starts threecalibration cycles.

The partial pressure and temperature measurements aredisplayed. On this display, the current calibration cyclenumber (cal:n) is also displayed in the bottom right-handcorner.

On completion of the three cycles, the instrument thenshows the sensitivity of the sensor as a percentage of thesensit ivity determined when cal ibration was lastperformed.

This percentage must be between 30% and 170% in order to calibrate. If the percentageis outside the limits, you will see the CALIBRATION OUT OF BOUNDS message. Youwill need to press ESC to continue. Check that the membrane does not need to bereplaced and that no leaks are evident.

If the percentage is within the limits press ENTER to accept and complete the calibrationprocess (the message CALIBRATION COMPLETE will appears briefly) or ESC to abort.

d ) Fraction calibration

This method uses a known purity of CO2, H2 or N2 gas at a known pressure, and requireseither the instrument internal barometric pressure sensor or an external pressure sensoras a reference. The pressure sensor is pre-calibrated at the factory. However, to checkor re-calibrate either pressure sensor, see “Barometric pressure sensor calibration” onpage 28 or “External pressure sensor calibration” on page 28.

To expose the sensor to the gas and to stabilize the reading, operate in MeasurementMode for about 30 minutes. After this time, press ESC and select CALIBRATE from themain menu, followed by SENSOR TC and FRACTION. Select your preferred unit ofmeasurement from the FRACTION CAL menu (either %vbar if using the barometricpressure sensor, or %vext if using the external pressure sensor), to bring up the menufor specifying the gas pressure.

Note :If you choose %vbar, the exit port of the flow chamber or sensor mounting must be open to the atmosphere.

Enter the concentration of the calibration gas in volume percent and proceed asdescribed above for Partial Pressure Calibration.

Note :If the sensor voltage slope shifts more than 1%, calibration restarts and the message Recal Err XXX% will appear. Three continuous calibrations with a shift of less than 1% must be performed, before the calibration can be completed.

e ) Dissolved calibration

This method requires a known concentration of CO2, H, or N2 dissolved in liquid as areference sample.

Select CALIBRATE from the main menu, followed by SENSOR TC and DISSOLVED.Select your preferred unit of measurement from the DISSOLVED CAL menu.

Enter the dissolved CO2 concentration of the sample and proceed as described abovefor Partial Pressure Calibration.

6 Accessories and attachments

Certain applications may require the use of one or more of the items described below.

6.1 Model 32605 purge backup unit

Since it is necessary to continuously purge the sensor to prevent the ingress of moisture,normally you would want to leave the instrument switched on at all times even when gasanalysis is not required. If it is more practical to be able to switch off an analyzer forseveral days at a time (without removing the sensor), a purge backup unit isrecommended.

Install the model 32605 Purge Backup Unit directly between the instrument and sensorusing the sensor cable. It is powered by internal batteries which batteries rechargeautomatically (using the sensor cable) when the instrument is switched on. When theinstrument is switched off, the purge backup unit continues to leave the sensor's solenoidin the open position (enabling purge gas entry) for up to four days. A green LEDilluminates when the battery is adequately charged; a red LED illuminates whenrecharging is necessary.

6.2 Model 32557/32559 external temperature sensor

This temperature sensor is ideal for applications where the sampling line or roomtemperatures undergo frequent change. It provides an independent temperature signalto the instrument that is not affected by room temperature. The temperature sensorconnects to an adapter that is factory-mounted to the rear of the model 31260, 31460, or31560 sensor (and available as a retrofit for model 31250, 31450, or 31550 sensors).The temperature sensor connects to this adapter using a 4-pin LEMO connector.

The model 32557 temperature sensor is mounted in-line in a pipe, using a model 29501sensor socket. The on-line temperature sensor, model 32559, is designed for mountingin 6-mm or ¼-inch stainless steel tubing.

6.3 Data acquisition software

The 3610 instrument can be used as an acquisition device through the Windows-compatible MOCA3610 PC program, available as model number 32681.E fromOrbisphere.

The program uses the instrument's RS-232 connection (ENABLED in the OptionsMenu, as described in “Serial output” on page 21) to set up a table of measurementinformation including gas, temperature, and time.

The program interfaces to any available RS-232 serial port on your computer. It may benecessary to run an independent utility on your PC in order to designate such a COMport.

a ) Program setup

This installation procedure will copy the contents of the MOCA3610 source floppy disk(designated here as drive A) onto your hard drive (designated here as drive C). About 80kilobytes of hard disk space will be required.

To setup the program using Windows, first place the floppy disk in its drive. Now, openWindows Explorer and copy the program, as follows:

7 Maintenance and troubleshooting

7.1 General maintenance

While unauthorized opening of the instrument normally voids the Orbisphere warranty, itis necessary to open the process instrument for output wiring connections.

Fuse replacement, AC voltage changes, and conversion from current to voltage outputalso can be performed by the user.

WARNINGDisconnect power before opening the instrument.

• To open a panel/rack mount or portable instrument, remove the front panel key and place the instrument face down. Remove the four 3-mm Allen head screws on the rear, and carefully pull off the rear panel, taking care not to disconnect any wires.

• To open a wall mount instrument, unlock the front panel of the unit with the key provided to expose the electronics inside.

a ) Internal fuse replacement

For panel/rack mount and portable instruments, the power supply is attached to theinside of the rear panel. For wall mount instruments, the power supply is located on therear panel of the instrument housing.

At position F1 on the power supply is a black plastic fuse holder. Remove the fuse coverusing a thin coin or a small flat-bladed screwdriver to push down and turn.

• The 230 VAC power supply uses a T 100 mA fuse.• The 115 VAC power supply uses a T 250 mA fuse.• The 10-30 VDC power supply uses a T 1.25 A fuse.

b ) AC voltage switch

A rotary 115/230 VAC switch is located next to the fuse holder (see “Internal fusereplacement” above). You can change this with a turn from a small flat-bladedscrewdriver. Check to see that the correct fuse for your voltage is installed beforeconnecting the instrument to a power supply.

c ) Alarm output jumper settings

The default factory setting is for Normally Open operation. You can change this toNormally Closed (or vice versa) by changing the J14 jumper settings.

Note :You can alternate between a Current and Voltage output simply by re-setting the appropriate jumpers as outlined in the tables above. However, If you need to change the Current output from 0-20 mA to 4-20 mA (or vice versa), contact your Orbisphere Service Representative first.

7.2 Instrument and sensor maintenance

Under normal operating conditions, your 3610 analyzer requires no maintenance. If theindicating instrument is properly connected, handled with reasonable care and keptclean, it should give you no mechanical or electrical problems.

Periodically, check the TC sensor calibration using a known standard. As long as thereading is ±1% of the expected value, no action needs to be taken. If the calibration haschanged ±1-10%, perform a new calibration. If the deviation is more than 10% of theoriginal values, a change of membrane may be required.

A visual inspection of the sensor face may also reveal any problem like dust deposits oraccumulation of dirt onto the protection grill.

The TC sensor will require regular servicing. For sensor servicing and membranereplacement details, please refer to the associated TC Sensors - Maintenance andInstallation Manual, which should have been delivered with your instrument.

8.1 Mounting

Note :For all mountings, include at least 100mm additional rear clearance for cable protrusion.

a ) Panel instrument installation

The standard panel mount instrument configuration is illustrated in Fig 21.

Use the model 32200 panel mount template as a guide for the necessary panel cuttingand drilling. To use, place the template where you wish to mount the instrument, andmark the drill holes and cut lines. Your mounting hardware includes a drill bit. Use this todrill the 5.4 mm holes required, then cut the 214.5 mm wide by 125.5 mm high panelholes.

Four self-clinching bolts secure the instrument to the panel. It is easiest to attach thebottom two bolts first, guide the instrument into place, and then fix the top two bolts tofinish the procedure. Once tightened, the self-clinching bolts ensure that only one personis required to remove the instrument.

A retrofit panel mount (model 32201) is also available. This enables users of existingOrbisphere analyzers to replace their instruments with the 3610 series, without additionaldrilling or panel cutting, as shown in Fig 22.

The instrument can also be mounted in a 19" rack, either one across (model 32202illustrated in Fig 23) or two across (model 32203 illustrated in Fig 24).

As with the panel mount configuration, four self-clinching bolts secure the instrument tothe rack panel.

8.2 Connections

a ) Power input

WARNINGThe installation of a 3610 instrument should only be performed by personnel specialized and authorized to work on electrical installations, in accordance with relevant European and/or national regulations. In accordance with safety standard EN 61010-1, it must be possible to disconnect the power supply of a 3610 instrument in its immediate vicinity. While the instrument electronics are well shielded, it is still advisable to locate the instrument as far as possible from any source of electromagnetic perturbation.

AC power input

CAUTION :Use a power supply cable type H05VV-F 3 X 0.75 mm2 (supplied with the instrument). The length of the cable should be three meters maximum and it should have a separable plug (with three connectors, L+N+PE), without a locking device, to mate with a socket outlet in the building. The cable and the plug must conform to an appropriate European or national standard.

For wall mount instruments, AC power connections use the right most waterproofcable gland (see illustration in Fig 25). The power cable must be wired according to thelabel inside the housing. Three FAST ON 6.3-mm spade-type connectors are suppliedwith the wall mount instrument for wires measuring from 0.5 - 1 mm2.

1) Remove the exterior insulation of the cable for a length of about 50 mm.2) Insert the cable through the right most cable gland.3) Strip the wires for a length of about 8 mm.4) Put a FAST ON (spade-type) connector on each of the three wires.5) Put the live, neutral, and earth wires on the corresponding spade plugs of the

mains filter, as indicated on the label affixed to the bottom of the wall mount box, opposite the filter.

6) Slide the cable farther through its cable gland until its external insulation penetrates about 6 mm inside the housing, blocking the cable gland.

For panel and portable instruments, AC power connections use a standard detachablepower cable on the rear panel of the instrument (as illustrated in Fig 27 and Fig 31).

10-30 VDC power inputNote :This is only applicable to the 3610/450 and 3610/550 panel mount instruments and the 3610/540 portable instrument.

DC powered instruments have a Male Binder connector on their rearpanel. It accepts 10-30 VDC power as follows:

• Pin 1: DC Return• Pin 2: Earth (Chassis)• Pin 3: Not connected• Pin 4: 10-30 Volts DC

The necessary DC power wiring connections must be made using the Female Binderconnector supplied. User-supplied power cable can have an outer diameter of between5mm and 8mm.

Disassemble the plug by squeezing the two clips located in the middle of the plug(position C in Fig 26). This reveals numbered wiring connections inside, to be matchedone-to-one with the Male Binder connector diagram above.

b ) Electrical signal connections

Connections to the gas sensor and (optional) external pressure sensor use pre-wiredLEMO receptacles on the rear of the panel mount and portable instruments, and on thebottom of the wall mount instrument housing. Fig 27 shows the rear of the panel mountinstrument with AC power input and optional external pressure sensor input. Fig 31shows the rear of the portable instrument and Fig 25 shows the wall mount instrument.

The supplied sensor cables have mating LEMO connectors. The LEMO connector pinassignments are identified in “Wiring identification” on page 57.

Note :Disconnect power to the instrument before removing any panels, and ground each cable shield securely to ensure proper operation.

Panel mount instrumentConnections for RS-232, recorder (analog) output, hold input, and alarm relays usewatertight cable glands on the instrument rear panel. These cables must be wired to aterminal strip inside the instrument. To make any of these connections, remove the rearinstrument panel.

8.6 Cable gland wiring instructions

The nickel-plated, brass cable glands are EMC-types, designed so that the cable shieldsattach directly to the instrument box. Typical cable wiring through one of these glands isillustrated in Fig 39.

1) Unscrew the cable gland nut. You will find a rubber gasket, then a metal washer with an interior diameter of 8.3 mm, and then another metal washer with an interior diameter of 7.5 mm.

2) Pass the cable through the nut, the gasket, and the 8.3-mm washer.3) Strip off 110 mm of external insulation, and 85 mm of shielding (see Fig 40).

4) Pass the cable prepared in this fashion through the 7.5-mm washer.5) Pinch the shield so that its entire circumference is pressed between the two

washers (as shown in Fig 39).6) Pass the cable into the box, blocking the cable gland.7) Reattach and tighten the cable gland nut.8) Strip the wires about 8 mm from their ends.9) Attach the wires to the corresponding terminal block connections, as follows:

For panel mount instrument terminal blocks, use a small-bladed flat screwdriverto gently push back the spring-loaded plastic lever on top of the terminal strip

connector. Insert the wire into the connector opening and release the lever to holdthe wire firmly in place.

For wall mount instrument terminal blocks, use a small-bladed flat screwdriver toloosen the screw at the top of the terminal block connector. Insert the wire into theconnector opening and tighten the screw to hold the wire firmly in place.

8.7 Sensor and sensor purge gas installation

The TC sensor has a threaded collar and storage cap, a screw-on protection capcovering the membrane, and a LEMO 10-pin connector for the sensor cable. The sensorcable has a mating screw-on connector, and a snap-in LEMO plug for connecting to theinstrument. The standard sensor cable length is three meters, but extension cables of upto 100 meters can be provided without any loss in signal sensitivity.

The TC sensor also has entry and exit ports for a purge gas supply. A LEMO 4-pinadapter may be mounted at the rear of the sensor to connect to an external temperaturesensor. When factory-fitted with the external temperature sensor adapter, the H2 sensoris designated model 3126x, the CO2 sensor is model 3146x, and the N2 sensor is model3156x.

For full instructions on sensor and sensor purge gas installation, please refer to the TCSensors - Maintenance & Installation Manual that was provided with your instrument.

8.8 Model 28117 pressure sensor installation

The pressure sensor can be mounted in the model 32002.x flow chamber. It is held inplace by a threaded, blue-colored aluminum collar. The pressure sensor 4-pin LEMOconnector plugs into the socket labeled pressure on the instrument. The maximum cablelength is 50 meters.

8.9 Analog outputs

The 3610 instrument provides a choice of three analog output signals of 0-5 Volts, 0-20mA, or 4-20 mA, which represent the measured CO2, H2, or N2 gas concentration,temperature, and pressure. See “Wiring identification” on page 57 for output wiringconnections and “Analog current/voltage output jumper settings” on page 42 for current/voltage output conversion.

The instrument generates these analog outputs using a 12-bit digital converter. Thus, theminimum increment of any output can be determined by dividing the output range by4096. For example: You could set the gas concentration range to 0-500 ppm for 4-20mA,and your recorder would still pick up changes of 0.122 ppm. The accuracy of eachincrement is 1%.

a ) Gas concentration output

You can scale the analog output signal of CO2, H2, or N2 concentration to vary betweenany two custom gas concentration levels. Instructions for setting these levels are in“Alarm and analog outputs” on page 20.

When ANALOG OUTPUT is DISABLED in these menus, the instrument scales the gasconcentration output to vary linearly with the measured gas concentration, from 0 to 9999(of the measurement units selected). The relation between the gas concentrationmeasurement M and the analog output signal V (voltage V) or I (current, mA) is as shownin Table 17.

When ANALOG OUTPUT is ENABLED, the instrument rescales outputs for each of thethree signals (4-20mA, 0-20mA and 0-5V) between any Low (L) and High (H) limits thatare defined in the Modify Options Menu (See “Alarm and analog outputs” on page 20.).The relationship between the analog output signal V (voltage V) or I (current, mA), andthe measurement M is represented in Table 18.

Using Table 18, the following is an example of the measurement calculation for a 16mAanalog signal (I) (on a 4-20mA configuration) and where the low and high limits aredefined as 10 (L) and 20 (H):

M = L + ((H - L) * ((I - 4) / 16))M = 10 + ((20 - 10) * ((16 - 4) / 16))M = 10 + (10 * 0.75)M = 10 + 7.5M = 17.5

This same calculation can also be represented graphically as illustrated in Fig 41.

The output upper limit is fixed at 20mA or 5V whenever the displayed concentration isequal to or exceeds the defined High limit value. Similarly, the output lower limit is fixed

8.10 Serial outputs

The instrument serial output provides formatted text for an RS-232 compatible printer,monitor, or computer interface (see “Serial (RS-232) wiring identification” on page 58 forserial output wiring connections). The pertinent RS-232 communications parametersare:

• Baud rate = 9600• Stop Bit = 1• Data Bits = 8• Parity = None• Flow Control = None

Instructions for selecting the serial output operating mode are in “Serial output” onpage 21.

EnabledThis output provides a running log of gas concentration plus sample temperature. It alsoincludes information on conditions that affect gas measurement as shown in the sampleoutput in Table 22.

The output generates a new row of headings (see line starting Concentration... in theTable 22 example) every sixteen measurement cycles. Concentration, Temperature,and Alrm values are as seen on the instrument's display. External pressure Pext isdisplayed in bars and barometric pressure Patm is displayed in mbars. If an offset hasbeen entered (see “Offset” on page 22), the Offset column shows the value. A codeappearing in the Status column signifies the following conditions:

• A = Rolling Average enabled• H = Humidity Correction enabled• T = Temperature Correction enabled

When enabled, the serial output also generates a report when you calibrate the sensoras shown in Table 23.

This example reveals an initial recalibration cycle of more than 1% (Recal err = 1.2%)outside normal limits, followed by successful calibration cycles.

DiagnosticsThis output selection provides several lines of hexadecimal codes indicating how yourinstrument is performing. In addition, when you return to Measurement mode afterselecting diagnostics, the serial output subsequently provides a running log of diagnosticresults for every measurement cycle, as shown in Table 24.

The first three columns of the diagnostics output indicate the sensor voltage at thebeginning and end of the purge cycle, and the calculated voltage Slope. Temp is thesample temperature and No is the output line number (1 to 9999). PartPres and StDvtrack deviations from expected conditions. H2O and Tcorr list humidity and temperaturecorrections applied (see “Corrections” on page 23).

If you want to bring this serial output information into your personal computer, it isadvisable to use Orbisphere's Windows data acquisition software described in “Dataacquisition software” on page 39. Otherwise, you may use a third-party communicationsoftware (such as Hyper Terminal).

8.11 Alarm outputs

Note :Alarm outputs are NOT applicable to series 3610/x10 and 3610/X40 instruments.

Two alarm relay outputs are available in most instrument configurations (see also “Alarmoutput wiring identification” on page 59 for alarm output wiring connections). Each alarmrelay can be set for Normally Open (NO) or Normally Closed (NC) operation - the factorydefault setting is Normally Open. If you wish to change the setting on your instrument,please refer to “Alarm output jumper settings” on page 41 for details.

The Alarm Outputs options menu gives you the choice of selecting the alarmconfiguration (Low/High or High/High-High). This configuration determines the mannerin which the alarm relays respond to various system or measurement conditions.

You can set your own alarm limits. If the measured gas concentration is outside of theselimits, the instrument activates the appropriate alarm relay. Instructions for selecting thealarm configuration and setting the alarm limits are in “Alarm and analog outputs” onpage 20.

Table 25 and Table 26 list all alarm conditions and alarm relay responses for youroptions settings.

The indicating instrument is available in 115 VAC, 230 VAC, and 10-30 VDC versions.Make sure that it is correct before connecting to a power supply, and make sure that theground of the AC supply is connected.

Note :While the instrument case is watertight, the detachable power cable connection is not.

b ) Check purge gas supply

It is critical that the TC sensor has a supply of purge gas running before operating thesystem. The TC sensor, when exposed to a liquid sample, could be damaged if the purgegas is not running.

For full details on the correct purge gas to use for your sensor, refer to the accompanyingTC Sensors - Maintenance & Installation Manual.

c ) Maintain instrument power at all times

The TC sensor must be purged continuously. The instrument does this automatically;thus make certain that power is supplied constantly to the instrument. If it is desirable tobe able to shut off the instrument while leaving the sensor installed in a liquid sample,install a model 32605 purge backup unit as described in “Model 32605 purge backupunit” on page 39.

d ) Alarm and recorder output testing

When connecting the alarm or recorder (analog) outputs to user-supplied equipment, itmay be helpful to verify the connections using a test signal from the instrument. For thispurpose, the 3610 instrument provides diagnostic signals for both the alarm output pinsand the recorder current (or voltage) gas concentration output pins.

When you set alarm and analog output limits using the Modify Options menus (see“Alarm and analog outputs” on page 20), an associated alarm or analog output testsignal is provided at the connections.

• The alarm limit selections of this menu set the high and low alarm relays. • The analog output selections of this menu apply a test current (or voltage) output

at the recorder output gas concentration pins.

The diagnostic outputs provided from the Modify Options menu procedures are:

The test alarm relay closure or analog signal remains on the output pins until you returnto the Main Menu.

Table 27 : Alarm and Recorder Diagnostic Outputs

Modify Options Selection Output Provided

Alarm, Low Limit Closure (*) of Low Alarm relay, Low Alarm Pin to Common

Alarm, High Limit Closure (*) of High Alarm Relay, High Alarm Pin to Common

Alarm, High-High Limit Closure (*) of both High Alarm Relay and Low Alarm Relay,High Alarm Pin and Low Alarm Pin to Common

Analog, Low Level 4mA (or 0mA or 0 Volts) applied to Gas Concentration Pins

Analog, High Level 20mA (or 5 Volts) applied to Gas Concentration Pins

(*) These alarm relay outputs are for Normally Open alarm relays. If the relays are set to Normally Closed, these relay outputs are the opposite, Opening instead of Closure (see “Alarm outputs” on page 66)
