1 Mounting and Location of DetectorsCautionThe location of the transmitters and sensors should be made in accordance withany relevant local and national legislation, standards or codes of practice. Alwaysreplace detectors with a detector of the same type. The detector should be mountedwhere the gas is most likely to be present. The following points should be notedwhen locating gas detectors.• Consider the possible damage caused by natural events e.g. rain or floodingwhen locating detectors.• Consider ease of access for functional testing and servicing.• Consider how escaping gas may behave due to natural or forced aircurrents.NoteThe placement of detectors should be determined following the adviceof experts having specialist knowledge of gas dispersion, experts havingknowledge of the process plant system and equipment involved, safety andengineering personnel. The agreement reached on the location of detectorsshould be recorded.1.1 Mounting the XNX Universal TransmitterThe XNX Universal Transmitter can be mounted in a number of different methodsusing the integral mounting tabs.Using the mounting tabs, the XNX can be attached to:• flat wall surface®• UnistrutWith the optional Pipe Mount kit, the XNX can be mounted to pipe of diameter 2 to6 in (50 to 150mm).A ceiling mount bracket kit (1226A0358) is also available.Integral Mounting LugsFigure 1.

Shield should provide 90% coverage.LoadingWiring for DC Power, 4-20mA Signal, remote wiring to sensors must be sizedsufficiently to provide sufficient voltages for the line length and the loads that willbe used.IsolationIsolating power and signal carrying conductors is recommended.Circuit ProtectionSupply circuits must provide over current protection. Class 2 power supplies arerequired for 24 volt DC supply. Consider Inrush current in specifying any DC supply.Power supply range is 16 to 32 VDC for EC and mV versions, 18 to 32 VDC for10XNX Universal Transmitter Quick Start Guide

Searchpoint Optima Plus and Searchline Excel and 16 to 32 VDC dependent onthe limitations of device for the generic 4-20mA input.LoadsThe use of High Inrush or Inductive loads may affect the performance of the XNX.For best reliability use resistive loads only.2.2 Distance Considerations for InstallationTypes of InstallationsThere are three basic types of installation: a single transmitter; multiple transmittersconnected to a single power source; and multiple transmitters connected in a “daisychain”configuration.Power Source SelectionThe power requirements for different transmitter configurations are:• XNX EC (Toxic): 6.2 watts• XNX mV (Catalytic): 6.5 watts• XNX IR with Searchpoint Optima Plus: 9.7 watts• XNX IR with Searchline Excel: 13.2 wattsWire SelectionThe type of wire used for connections has an effect on the distance of theinstallation. This is because some of the voltage is lost in the wire on the way tothe transmitter.Single Transmitter DistancesFor installations that have dedicated wiring between the transmitter and the powersupply, use the following chart. These distances assume stranded wire is used.ORClass 2Power SupplyClass 2Power SupplyXNX mV or ECWith SensorXNX IR withSearchpoint Optima PlusXNX IR withSearchline ExcelSingle Transmitter Distances18 AWG[1.0 mm 2 ]1140 feet[347 meters]660 feet[201 meters]550 feet[168 meters]16 AWG[1.5 mm 2 ]1810 feet[551 meters]1060 feet[323 meters]890 feet[270 meters]14 AWG[2.0 mm 2 ]2890 feet[880 meters]1690 feet[515 meters]1410 feet[430 meters]12 AWG[3.5 mm 2 ]4620 feet[1408 meters]2690 feet[820 meters]2260 feet[690 meters]NoteIf multiple transmitters are using the same power supply, make sure thepower supply wattage rating is high enough to power all transmitterssimultaneously.XNX Universal Transmitter Quick Start Guide 11

1. When mounting the Searchline Excel or Searchpoint Optima Plus, run wiringconnections between each Excel or Optima and the XNX in a dedicatedseparate conduit. Cable length should not exceed 4000 feet.2. Use 16AWG twisted shielded cable for the RS485 connection between Excelor Optima and the XNX. Make sure that the shield of the cable is groundedto earth and XNX ground on one end ONLY.3. Avoid running wiring near mains cables or other high voltage equipment.4. DO NOT APPLY 120 Ohm terminating resistors. These resistors are notrequired due to low data rates.5. HA recommends that Excel or Optima and the XNX be wired to buildingground. The system should be grounded at one point only.Installation Tip:Always issue a soft reset after connecting the Optima and XNX for the first time. The softreset is performed by accessing the XNX calibration menu.XNX Universal Transmitter Quick Start Guide 27

3 Options3.1 Local HART ® HandheldAvailable with any sensor technology or option, this option provides an externalaccess to the HART ® interface in the XNX. An IS barrier inside the XNX allows theuser to attach an external hand-held interrogator for programming and configuration.The external interface is installed in the lower left cable/conduit entry of the XNXand is intrinsically safe (IS).Intrinsically Safe Barrierfor HART InterfaceHART Handheld InterfaceConnector w/Protective CapFigure 22. XNX Universal Transmitter with HART ® Interface IS Barrier installedHART ® devices can operate in one of two configurations - point-to-point ormultidrop.Point-to-Point ModeIn point-to-point mode, the 4–20 mA signal is used to communicate one processvariable, while additional process variables, configuration parameters, and otherdevice data are transferred digitally via HART ® protocol. The 4–20 mA analog signalis not affected by the HART ® signal.Multidrop ModeThe multidrop mode of operation requires only a single pair of wires and, if applicable,safety barriers and an auxiliary power supply for up to 8 field devices.Note:Use multidrop connection for supervisory control installations that arewidely spaced, such as pipelines, custody transfer stations, and tankfarms.The minimum conductor size is 0.51mm diameter (#24 AWG) for cable runs lessthan 1,524m (5,000 ft) and 0.81mm diameter (#20 AWG) for longer distances.Cable LengthMost installations are well within the 3,000m (10,000 ft) theoretical limit for HART ®communication. However, the electrical characteristics of the cable (mostlycapacitance) and the combination of connected devices can affect the maximumallowable cable length of a HART ® network. The table in Figure 23 shows the affectof cable capacitance and the number of network devices on cable length. The tableis based on typical installations of HART ® devices in non-IS environments, i.e. nomiscellaneous series impedance.32XNX Universal Transmitter Quick Start Guide

6.1 CalibrationCautionThe calibration procedure should only be performed by qualified personnel.Note:HA recommends that the maximum calibration interval be 30 days or inaccordance with customer site procedures to assure the highest level ofsafety. Correct operation of each sensor/detector should be confirmed withtest gas of known concentration before each use.See Section 7 - XNX Electrochemical Sensor Data for Calibration Gasspecifications.6.1.1 Calibration ProcedureNote:Follow the specific procedure outlined in the Operating Manual for eachsensing device.1. If using compressed gas cylinder, attach the calibration gas flow housingonto the bottom of the sensor and apply the gas.2. Access the calibration mode.Figure 40. Gas Calibration MenuNOTE:The Gas Calibration menu is for both Zero and Span Calibration.Zero CalibrationSensor Readingat Current SettingsFigure 41. Zero Calibration ScreenFigure 42. Zero Calibrationin ProgressSelect then apply the zero gas. As the sensor detectsthe gas and the concentration increases, the valuesdisplayed will reflect the changing concentration.Selecting will return to the Gas Calibration menu.3. I f t h e Z e r oCalibration is successful, the XNX UniversalTransmitter will display the Zero Passedscreen.Figure 43. ZeroCalibration PassedXNX Universal Transmitter Quick Start Guide 43

When the Zero Calibration is complete or it is skipped, the SpanConcentration screen appears to indicate the concentration value of thegas used for calibration.Figure 44. Span Gas Concentration Screen5. Select to choose the first digit and use the switches to increment ordecrement the values. Select to accept the new value and move to the nextdigit. Continue until all 3 digits have been selected.Sensor Readingat Current SettingsCalibration GasConcentrationFigure 45. Span Calibration Screen6. Select then apply the target gas. As the sensor detects the gas and theconcentration increases, the sensor reading values in the display will changeto reflect the changing concentration.7. When the concentration values stabilize, the gas concentration as read bythe installed sensor is stable. At this time, the gas readings are taken by thesensor. The Span Calibration process also determines whether the sensoris within the proper range to accurately detect the target gas.8. When the sensor has completed the calibration and the span algorithms havedetermined that it is within range, the Span Passed screen will appear.If the calibration is not successful, the Span Failed screen will display. Selecting will return to the Span Concentration screen to begin the span calibration again. will exit Span Calibration and return to the Main Calibrate screen.Arrow indicatesgas values too lowSelecting ‘’ returns tothe Span ConcentrationscreenFigure 46. Span Calibration FailedOnce the Zero and Span calibrations are completed successfully, the XNX will exitthe calibration procedure. Before returning to the Gas Calibration menu however,the user will be prompted to Exit and turn alarm and fault inhibit off. The user canExit and leave the XNX in inhibit mode, or do not exit.44XNX Universal Transmitter Quick Start Guide

WarningWhile XNX is in Inhibit Mode, alarms are silenced. This will prevent an actual gasevent from being reported. Inhibit Mode must be reset after testing or maintenanceactivities.6.1.2 Zero and Span Calibration for XNX EC SensorsCautionBefore initial calibration, allow the detector to stabilize for 30 minutes afterapplying power. When in zero and span calibration mode, the current output fromthe detector is inhibited (default 3mA) to avoid false alarms.It is recommended for most sticky gases (i.e.: HCl, Cl 2) the tubing should be PTFEwith short pieces of rubber tube to make the final connection due to the inflexibilityof PTFE. This minimizes adhesion of the gas to the tube surface and allows formore accurate measurement.Recalibration is recommended if the temperature of local environment has variedby more than +/-15 degrees C from the temperature of calibration.To calibrate the detector, use an appropriate span gas cylinder, flow regulator setto 300-375mL/min, tubing, magnet and calibration gas flow housing. A compressedgas cylinder (20.9%Vol oxygen) should be used to perform the zero calibration if thearea where the detector is located contains any residual amount of the target gas. Ifno residual gas is present then the background air can be used to perform the zerocalibration. Contact your HA representative for details of suitable calibration kits.To calibrate the detector follow the procedure in Section 6.1.1.Note:The Oxygen sensor does not require a zeroing procedure. Background air(20.9%Vol oxygen) can be used to span the oxygen sensor in place of acompressed air cylinder (20.9%Vol oxygen).6.1.3 Zero and Span Calibration of XNX EC Hydrogen Sulfide (H 2S) SensorsCautionBefore initial calibration, allow the detector to stabilize for 30 minutes afterapplying power. When in zero and span calibration mode, the current output fromthe detector is inhibited (default 3mA) to avoid false alarms.Recalibration is recommended if the temperature of local environment has variedby more than +/-15 degrees C from the temperature of calibration.Hydrogen Sulfide sensors can be affected by extreme humidity changes.A sudden increase in ambient humidity can result in a short-term positivedrift in the instrument’s reading. A sudden decrease in ambient humidity canXNX Universal Transmitter Quick Start Guide 45

esult in a short-term negative drift in the instrument’s reading. These aremost likely to be noticed during calibration with dry or cylinder gas.When calibrating Hydrogen Sulfide cartridges the following should be taken intoaccount while following the procedure in Section 6.1.1:1. To zero the sensor, use a compressed gas cylinder of 20.9%Vol oxygen(not Nitrogen). Do not use background air.2. If a span calibration is to be performed, the span calibration gas should be appliedto the sensor immediately after the zeroing procedure. Do not allow the sensor toreturn to ambient air conditions.6.1.4 XNX EC Sensor Operational LifeTypical life of a toxic gas sensor is dependent on the application, frequency and amountof gas exposure. Under normal conditions, with a 3 month visual inspection and 6 monthtest/re-calibration, the toxic sensor has an expected life equal to or greater than thelifetime as listed below:• 18 months for Chlorine and Chlorine Dioxide sensors.• 12 months for Ammonia and Hydrogen Fluoride sensors. (See Ammonia notebelow.)• 24 months for Oxygen and other toxic sensors.CautionOxygen deficient atmospheres (less than 6%V/V) may result in inaccuracy ofreading and performance.Note:Ammonia electrochemical cells are reliable and suitable for applications where nobackground concentration of ammonia exists. Under these conditions the cellsare expected to operate for 12 to 24 months.These ammonia cells are of the consumptive type. Their operating life can beadversely affected by continuous or excessive exposure to ammonia, or byprolonged exposure to high temperatures and moisture.To ensure continued detection availability, it is recommended that the detectors areregularly bump tested and a relevant cell replacement program be implemented.6.1.5 Zero and Span Calibration for MPD SensorsCautionBefore initial calibration allow, the detector to stabilize for 30 minutes afterapplying power. When in zero and span calibration mode, the current output fromthe detector is inhibited (default 3mA) to avoid false alarms.This section describes how to calibrate MPD flammable sensors fitted to the XNX.The calibration adjustments are made on the XNX’s display and gassing is performedat the sensor. This may be locally or remotely located.46XNX Universal Transmitter Quick Start Guide

The following equipment is required:• Flow Housing (Part No: 1226A0411)• Test gas• RegulatorNote:Zero gas and Span gas should be at roughly the same humidity levels toavoid erroneous cell responses.1. At the MPD, remove the Weatherproof Cap if equipped.2. Fit the Flow Adaptor onto the MPD.Figure 47. Flow AdaptorReverse the cap removal procedure. The following diagram shows the Flow Adaptoraccessory fitted to the MPD.Figure 48. MPD with Flow AdaptorNOTEThe Gas Calibration menu is for both Zero and Span Calibration.3. Connect the Flow Adaptor (using either gas pipe) to the regulated cylindercontaining a known concentration of the target gas at approximately thesensor alarm point (e.g. 50% LEL Methane in air).WARNINGAs some test gases may be hazardous, the Flow Housing outlet should exhaustto a safe area.4. Follow the procedure in Section 6.1 for both Zero and Span calibrations.5. Apply the target gas to the sensor. Pass the gas through the flow housingat a rate of between 0.7l/m and 1.0l/m.XNX Universal Transmitter Quick Start Guide 47

Note:Sensors should be calibrated at concentrations representative of those to bemeasured. It is always recommended that the sensor is calibrated with the targetgas it is to detect.CautionWhere the user calibrates any sensor using a different gas, responsibility foridentifying and recording calibration rests with the user. Refer to the localregulations where appropriate.6. Ensure that the sensor and the vicinity around it is clear all traces of thecalibration gas before continuing. This is to avoid triggering spuriousalarms. If calibration fails at any point, discard the cartridge and replace with anew one.7. Remove the test equipment, refit the weatherproof cap to the sensor (ifpreviously removed for the test) and return the system to normal operation.6.1.6 Cross Calibration procedure for MPD-CB1CAUTIONWhere the user calibrates any sensor using a different gas, responsibility foridentifying and recording calibration rests with the user. Refer to the localregulations where appropriate.When the MPD-CB1 Combustible LEL sensor is to be calibrated with a gas which isdifferent to the gas or vapor to be detected, the following cross calibration procedureshould be followed:NOTE• Table 1 lists the gases according to the reaction they produce at a givendetector.• An eight star (8*) gas produces the highest output, while a one star (1*)gas produces the lowest output.

To cross calibrate the MPD-CB1 combustible gas sensor:1. Obtain the star rating for both the test gas and the gas to be detected fromTable 1.2. These values may then be used in Table 2 to obtain the required metersetting when a 50% LEL test gas is applied to the detector.* Rating ofCalibrationGas* Rating of Gas to be Detected8* 7* 6* 5* 4* 3* 2* 1*8* 50 62 76 95 - - -7* 40 50 61 76 96 - -6* 33 41 50 62 78 98 -5* 26 33 40 50 63 79 100 -4* 21 26 32 40 50 63 80 -3* - 21 26 32 40 50 64 812* - - - 25 31 39 50 641* - - - - 25 31 39 50Table 2. Meter SettingsNOTEThese settings must only be used with a calibration gas concentration of 50% LEL.3. If a sensor is to be used to detect a gas other than that for which it wascalibrated, the required correction factor may be obtained from Table 3. Themeter reading should be multiplied by this number in order to obtain thetrue gas concentration.Sensorcalibrated todetectSensor used to detect8* 7* 6* 5* 4* 3* 2* 1*8* 1.00 1.24 1.52 1.89 2.37 2.98 3.78 4.837* 0.81 1.00 1.23 1.53 1.92 2.40 3.05 3.906* 0.66 0.81 1.00 1.24 1.56 1.96 2.49 3.175* 0.53 0.66 0.80 1.00 1.25 1.58 2.00 2.554* 0.42 0.52 0.64 0.80 1.00 1.26 1.60 2.033* 0.34 0.42 0.51 0.64 0.80 1.00 1.27 1.622* 0.26 0.33 0.40 0.50 0.63 0.79 1.00 1.281* 0.21 0.26 0.32 0.39 0.49 0.62 0.78 1.00Table 3. Meter Multiplication FactorsNOTESince combustible sensors require oxygen for correct operation, a mixtureof gas in air should be used for calibration purposes. Assuming averageperformance of the sensor, the sensitivity information in Tables 1 to 3 isnormally accurate to +20%.EXAMPLEIf target gas to be detected is Butane and the calibration gas available is Methane(50% LEL):XNX Universal Transmitter Quick Start Guide 49

1. Look up the star rating for each gas in Table 1: Butane 4* and Methane 6*.2. Check the meter settings for 50% LEL calibration gas in Table 2: 78.3. The meter should therefore be set to 78% to give an accurate reading forButane using 50% LEL Methane as a calibration gas.NOTEIt is important to calibrate the sensor at the approximate alarm levels to allowfor non-linearity of the sensors at gas concentrations above 80% LEL.6.1.7 Calibrating the 705/705HTFor more complete calibration and configuration information, see the Type 705Operating Instructions (p/n:00705M5002).6.1.8 Calibrating the Sensepoint/Sensepoint HTFor more complete calibration and configuration information, see the SiegerSensepoint Technical Handbook (p/n:2106M0502).6.1.9 Calibrating the Searchline Excel and Searchpoint Optima PlusComplete calibration and configuration information can be found in the SearchlineExcel Technical Handbook (p/n:2104M0506) and the Searchpoint Optima PlusOperating Instructions (p/n:2108M0501).6.2 Functional Gas Testing (Bump Test)WARNINGIt is recommended to bump test the sensors frequently to ensure proper operation.It is recommended that the detector is tested frequently to ensure the system isoperating properly. Keep in mind different sensor types may require more frequentmaintenance depending on the environmental conditions and gases present. Theweatherproof cover has a spigot for attaching tubing from a gas cylinder. This maybe used for a simple functional (or bump) test of the sensor. However, this methodmay not be suitable for all gas types and/or applications due to environmentalconditions. It is the responsibility of the user to ensure suitability of this method foreach application.1. When bump gas is applied to the sensor, the bump test screen displaysthe current reading of the sensor and the peak reading that has occurredduring the bump test.Peak ReadingCurrent SensorReadingFull Scale50Alarm LevelsFigure 49. Bump Test Screen2. If the difference between reading and applied gas concentration is outsidethe acceptable limits for the application follow the procedures for zeroing andcalibrating the detector (see Section 6.1).3. If reading is still inaccurate replace the sensor.XNX Universal Transmitter Quick Start Guide
