XNX Universal Transmitter2.1 Mounting and Location of DetectorsCautionThe location of the transmitters and sensors should be made inaccordance with any relevant local and national legislation, standardsor codes of practice. Always replace detectors with a detector of thesame type. The detector should be mounted where the gas is mostlikely to be present. The following points should be noted when locatinggas detectors.• When locating detectors consider the possible damage causedby natural events e.g. rain or flooding.• Consider ease of access for functional testing and servicing.• Consider how escaping gas may behave due to natural or forcedair currents.NoteThe placement of detectors should be determined following theadvice of experts having specialist knowledge of gas dispersion,experts having knowledge of the process plant system andequipment involved, safety and engineering personnel.

XNX Universal Transmitter2.2 Wiring the XNXThe XNX is available in 3 basic personalities (versions) whichsupport a variety of detectors and applications. Each of the availablepersonalities use dedicated interface boards. Pluggable terminal blocksare used for easy connection and service. The personality boards andoptional interfaces are enclosed in the electronics POD (Personality,Options and Display).The Personality circuit board determines the XNX behavior based onthe sensor type attached to the XNX interface (See Figure 2-7).The table below defines the three XNX transmitter configurations andthe sensors each support.Searchline ExcelXNX IR PersonalitySearchpoint Optima Plus Local/RemoteGeneric mA SensorsXNX mV PersonalityXNX EC PersonalityXNX EC SensorXNX EC Sensor Remote Mount Kit705 Local / Remote MPD Local (cat bead and IR) Sensepoint Local / Remote705HT Local / Remote MPD Remote Sensepoint PPM Local/RemoteSensepoint HT RemoteCautionBefore wiring the XNX, confirm the correct personality boards andoptions are installed.2.2.1 General Wiring ConsiderationsFor proper operation of the XNX Universal Transmitter and sensortechnologies, consideration of wiring induced voltage drops, transientelectrical noise and dissimilar earth ground potentials is imperative inthe design and installation of the system.Note:To maintain EMC integrity, wiring must be shielded by eitheran integral shield or run through conduit or pipe. Shield shouldprovide 90% coverage.LoadingWiring for DC power, 4-20mA signal, remote wiring to sensors mustbe sized sufficiently to provide sufficient voltages for the line lengthand the loads that will be used.IsolationIsolating power and signal carrying conductors is recommended.Circuit ProtectionSupply circuits must provide over current protection. Class 2 powersupplies are required for 24 volt DC supply. Consider inrush currentin specifying any DC supply. Power supply range is 16 to 32 VDC forEC and mV versions, 18 to 32 VDC for Searchpoint Optima Plus andSearchline Excel and 16 to 32 VDC dependent on the limitations ofdevice for the generic 4-20mA input.LoadsThe use of high inrush or inductive loads may affect the performanceof the XNX. For best reliability use resistive loads only.2.2.2 Distance Considerations for InstallationProviding power to the transmitter is the factor that will determine themaximum distance of the installation. The 4-20 mA output signal willeasily handle the distance back to the control equipment.Section 2 - Installation and Operation 2-52.2 Wiring the XNX

XNX Universal TransmitterThe primary factors determining distance are: minimum operatingvoltage of the transmitter and/or sensor; maximum current draw of thetransmitter/sensor, resistance of the wire used, power supply voltageand current capacity of power supply.An additional consideration is the type of installation; specifically, howmany transmitters/sensors are drawing power from the same powersupply and whether these transmitters are using the same pair of wires(“daisy-chain”) or have their own connections.Types of InstallationsThere are three basic types of installation: a single transmitter;multiple transmitters connected to a single power source; and multipletransmitters connected in a “daisy-chain” configuration.Single TransmitterThis is the simplest type of installation. It consists of a single XNXtransmitter installation per power source.Advantages:Class 2Power SupplyClass 2Power SupplyClass 2Power SupplyFigure 2-4. Single Transmitter Installation• Maximum distance between power source and transmitter.• Smaller power source.• If a power source fails, only one monitoring point fails.Disadvantages:• Multiple transmitters require multiple power sources.Multiple Transmitters Connected to a Single Power SourceThis is two or more transmitters sharing a single power source with eachtransmitter having its own dedicated wiring to the power source.Class 2Power SupplyFigure 2-5. Multiple Transmitters Powered by a Single Power SupplyAdvantages:• Maximum distance between power source and transmitters.• Fewer power sources.Disadvantages:• Larger power source will be needed.• If a power source fails, several monitoring points fail.Multiple Transmitters Connected in a “Daisy-Chain”ConfigurationThis configuration consists of two or more transmitters installed ina line. The power connections are installed as an extension of theprevious transmitter, with the first transmitter being the only oneactually wired to the power source.Class 2Power SupplyFigure 2-6. “Daisy-Chained” Transmitters from One Power SupplyAdvantages:• Less wire needed for installation.• Fewer power sources.Section 2 - Installation and Operation 2-62.2 Wiring the XNX

XNX Universal TransmitterDisadvantages:• Larger power source will be needed.• Shorter distance between power source and transmitters.• If a power source fails, several monitoring points go out.Power Source SelectionFor each type of installation, selection of power supply is important.Power supplies are rated by voltage and power. The nominal voltagefor all XNX transmitters is 24V and the power required depends onthe number of points using the same power supply.As a general guideline, the power supply should be capable of providingmore power than is required by the installation. A 10 watt power supplyis fine for a single XNX mV with catalytic sensor (6.5 watts required)but is not a good idea for a single XNX IR with Searchpoint OptimaPlus (10 watts required).To determine the wattage required, add the maximum powerrequirements of all the points that will be sharing the power supply.For example, two XNX mV transmitters with catalytic sensors (6.5watts each) and one XNX IR with Searchpoint Optima Plus (10 watts)require a 23 watt power supply (absolute minimum). A 25 watt powersupply will probably handle this installation, but a 30 watt power supplywill be a better choice.The 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 distanceof the installation. This is because some of the voltage is lost in thewire on the way to the transmitter.Thinner wire (i.e. 18 AWG) will lose more voltage than thicker wire (i.e.12 AWG). The amount of voltage lost depends on how much poweris being drawn through the wire; more power means more loss. If toomuch voltage is lost in the wiring, there may not be enough voltageat the distant point to allow the transmitter to operate.Distance Chart for Single Transmitter DistancesFor installations that have dedicated wiring between the transmitterand the power supply, use the following chart.

XNX Universal TransmitterEach of the personalities use a single terminal block for connectionwith the exception of the IR personality, which necessitates the useof a second terminal block.The personality boards also provide a dedicated pair of jumperswitches to define output of the XNX as isolated 4-20mA, Sink 20mAor Source 20mA as well as a service jumper to allow power to theloop to continue if the XNX is being serviced. A separate connectoris used to activate local HART ® (see Section 2.3.1).Local HART ® provides an external access to control the XNX. An ISbarrier inside the XNX allows the user to attach an external handheldinterrogator for programming and configuration. The externalinterface is installed in the lower left cable/conduit entry of the XNXand is intrinsically safe (IS).Note:Open loop faults are not available due to HART and Modbusinterfaces where a 4-20 may not be used. In this case, openloop, 0mA, must be used as the diagnostic.The Option circuit boards vary dependent upon the option selected atorder time. Only one of the 2 available interface options (Modbus ® orRelays) can be attached to the XNX. When installed, connections tothe options are made to connectors at the bottom of the POD.2.2.4 4-20mA Output, Common Connections and PowerSetting 4-20mA operation; S1 & S2The XNX Universal Transmitter allows the user to configure the4-20mA output to Sink, Source or Isolated mode operation via twoprogramming switches on the POD.

The 4–20 mA analog signal is not affected bythe HART ® signal.Multidrop ModeThe multidrop mode of operation requires only a single pair of wiresand, if applicable, safety barriers and an auxiliary power supply forup to 8 field devices (Figure 2-25). All process values are transmitteddigitally. In multidrop mode, all field device polling addresses are >0,and the current through each device is fixed to a minimum value(typically 4 mA).Control System orOther Host ApplicationHandheld TerminalMultiplexerControl Systemor Other Host ApplicationInput/Output (I/O) SystemNote: Instrument power is provided by an interfaceor external power source that is not shown.BarrierField DeviceNote: Instrument power is provided by an interfaceor external power source that is not shown.Handheld TerminalFigure 2-24. Point-to-Point Mode of OperationField DevicesFigure 2-25. Multidrop Mode of OperationNoteUse multidrop connection for supervisory control installationsthat are widely spaced, such as pipelines, custody transferstations, and tank farms.In general, the installation practice for HART ® devices is the same asconventional 4-20mA instrumentation. Individually shielded twisted paircable, either in single-pair or multi-pair varieties, is the recommendedwiring practice. Unshielded cables may be used for short distances ifambient noise and cross-talk will not affect communication.Section 2 - Installation and Operation 2-232.3 Options

XNX Universal Transmitter3.1 Gas Calibration MenuEach of the sensor technologies supported by the XNX UniversalTransmitter uses unique calibration procedures. The descriptionprovided illustrates the XNX interface to the sensor device and doesnot replace the procedures found in each device operating manual.For the XNX EC sensors, the calibration procedure is covered inSection 3.2.2.The Gas Calibration menu is used for Zero and Span calibration aswell as functional gas testing (bump test). The Gas Calibration menuis accessed from the main menu screen.Figure 3-1. Gas Calibration MenuGas CalibrationBump TestCalibrate mA OutputSoft ResetAlign Excel3.2 CalibrationCautionThe calibration procedure should only be performed by qualifiedpersonnel.Note:Honeywell Analytics recommends that the maximum calibrationinterval be 30 days or in accordance with customer siteprocedures to assure the highest level of safety. Correctoperation of each sensor/detector should be confirmed withtest gas of known concentration before each use.See Section 6 - Specifications for Calibration Gas specifications.3.2.1 Calibration ProcedureThe following section outlines the steps for calibrating the XNX attachedsensors. Calibration information for specifc sensors follows.Note:Follow the specific procedure outlined in the Operating Manualfor each sensing device.1. If using compressed gas cylinder, push the calibration gas flowhousing onto the bottom of the sensor and apply the gas.2. Access the calibration mode.Figure 3-2. Gas Calibration MenuNOTE:The Gas Calibration menu is for both Zero and Span Calibration.Section 3 - Calibration 3-2

XNX Universal TransmitterZero CalibrationSensor Readingat Current Settings4. When the Zero Calibration is complete, the Span Concentrationscreen appears to indicate the concentration value of the gasused for calibration. If Span is skipped, the user is returned tothe Gas Calibration Screen.Figure 3-3. Zero Calibration ScreenApply the zero gas. As the sensor detects the gas and theconcentration is increasing, the values displayed will reflect thechanging concentration. When the concentration values arestable select to allow the XNX to calculate the zero adjustment.Selecting will return to the Gas Calibration menu.Figure 3-6. Span Gas Concentration Screen5. Indicate the concentration of the span gas to be used by selecting to choose the first digit and use the switches to incrementor decrement the values; accepts the new value and move tothe next digit. Continue until all 3 digits have been selected.Figure 3-4. Zero Calibration in Progress3. If the Zero Calibration is successful, the XNX UniversalTransmitter will display the Zero Passed screen.Figure 3-5. Zero Calibration PassedSpan CalibrationNOTE:If a Span Calibration is not required, select the to skip theSpan Calibration and return to the Calibration menu.Section 3 - Calibration 3-3Sensor Readingat Current SettingsFigure 3-7. Span Calibration ScreenCalibration GasConcentration6. Apply the span gas. As the sensor detects the gas and theconcentration is increasing, the values displayed will reflectthe changing concentration. When the concentration valuesare stable select to perform the span. The Span Calibrationprocess also determines whether the sensor is within the properrange to accurately detect the target gas.Selecting will return to the Gas Calibration menu.7. When the sensor has completed the calibration and the spanalgorithms have determined that it is within range, the SpanPassed screen will appear.3.2 Calibration

Span Passed ScreenIf the calibration is not successful, the Span Failed screen will display.Selecting will return to the Span Concentration screen to begin thespan calibration again. will exit Span Calibration and return to theMain Calibrate screen.Arrow indicatesgas values too lowFigure 3-9. Span Calibration FailedSelecting ‘’ returns tothe Span ConcentrationscreenOnce the Zero and Span calibrations are completed successfully, theXNX will exit the calibration procedure. Before returning to the GasCalibration menu however, the user will be prompted to Exit and turnalarm and fault inhibit off, Exit and leave the XNX in inhibit mode, ordo not exit.WarningWhile XNX is in Inhibit Mode, alarms are silenced. This will preventan actual gas event from being reported. Inhibit Mode must be resetafter testing or maintenance activities.Section 3 - Calibration 3-43.2.2 Zero and Span Calibration for XNX EC SensorsCautionBefore initial calibration allow the detector to stabilize for 30 minutesafter applying power. When in zero and span calibration mode thecurrent output from the detector is inhibited (default 2mA) to avoidfalse alarms.It is recommended for most sticky gases (i.e.: HCl, Cl 2) the tubingshould be PTFE with short pieces of rubber tube to make thefinal connection due to the inflexibility of PTFE. This minimizesadhesion of the gas to the tube surface and allows for more accuratemeasurement.Recalibration is recommended if the temperature of local environmenthas varied by more than +/-15 degrees C from the temperature ofcalibration.To calibrate the detector, use an appropriate span gas cylinder, flowregulator set to 300-375mL/min, tubing, magnet and calibration gasflow housing. A compressed gas cylinder (20.9%Vol oxygen) shouldbe used to perform the zero calibration if the area where the detectoris located contains any residual amount of the target gas. If no residualgas is present then the background air can be used to perform thezero calibration. Contact your Honeywell Analytics representative fordetails of suitable calibration kits.To calibrate the detector follow the procedure in Section 3.2.1.Note:The Oxygen sensor does not require a zeroing procedure. Backgroundair (20.9%Vol oxygen) can be used to span the oxygen sensor inplace of a compressed air cylinder (20.9%Vol oxygen).3.2 Calibration

XNX Universal Transmitter3.2.3 Zero and Span Calibration of XNX EC HydrogenSulfide (H 2S) SensorsCautionBefore initial calibration allow the detector to stabilize for 30 minutes afterapplying power. When in zero and span calibration mode the current outputfrom the detector is inhibited (default 2mA) to avoid false alarms.Recalibration is recommended if the temperature of local environmenthas varied by more than +/-15 degrees C from the temperature ofcalibration.Hydrogen Sulfide sensors can be affected by extreme humiditychanges. A sudden increase in ambient humidity can result in a shorttermpositive drift in the instrument’s reading. A sudden decreasein ambient humidity can result in a short-term negative drift in theinstrument’s reading. These are most likely to be noticed duringcalibration with dry or cylinder gas.When calibrating Hydrogen Sulfide cartridges the following should betaken into account while following the procedure in Section 3.2.1:1. To zero the sensor, use a compressed gas cylinder of 20.9%Voloxygen (not Nitrogen). Do not use background air.2. If a span calibration is to be performed, the span calibration gas shouldbe applied to the sensor immediately after the zeroing procedure. Donot allow the sensor to return to ambient air conditions.3.2.4 XNX EC Sensor Operational LifeTypical life of a toxic gas sensor is dependent on the application, frequencyand amount of gas exposure. Under normal conditions (3 month visualinspection and 6 month test/re-calibration) the toxic sensor has an expectedlife equal to or greater than the lifetime as listed below:• 18 months for Chlorine and Chlorine Dioxide sensors.• 12 months for Ammonia and Hydrogen Fluoride sensors. (SeeAmmonia note below).• 24 months for oxygen and other toxic sensors.See Section 4 - Maintenance for sensor replacement procedures.CautionOxygen deficient atmospheres (less than 6%V/V) may result ininaccuracy of reading and performance.Note:Ammonia electrochemical cells are reliable and suitable forapplications where no background concentration of ammonia exists.Under these conditions the cells are expected to operate for 12 to24 months.These ammonia cells are of the consumptive type. Their operatinglife can be adversely affected by continuous or excessive exposureto ammonia, or by prolonged exposure to high temperatures andmoisture.To ensure continued detection availability it is recommended that thedetectors are regularly bump tested and a relevant cell replacementprogram be implemented.Section 3 - Calibration 3-53.2 Calibration

XNX Universal Transmittertriggering spurious alarms.If calibration fails at any point discard the cartridge and replacewith a new one (see Section 4.1).7. Remove the test equipment, refit the weatherproof cap to thesensor (if previously removed for the test) and return the systemto normal operation.3.2.6 MPD Flammable Sensor Operational LifeThe pellistors used in the flammable gas sensor can suffer froma loss of sensitivity when in the presence of poisons or inhibitors,e.g. silicones, sulfides, chlorine, lead or halogenated hydrocarbons.The pellistors are poison resistant to maximize the operational lifeof the flammable sensor. A typical operating life of IR sensors is 60months.3.2.7 Calibrating the 705/705HTFor more complete calibration and configuration information, see theType 705 Operating Instructions (p/n:00705M5002).3.2.8 Calibrating the Sensepoint/Sensepoint HTFor more complete calibration and configuration information, see theSieger Sensepoint Technical Handbook (p/n:2106M0502).3.2.9 Calibrating the Searchline Excel andSearchpoint Optima PlusComplete calibration and configuration information can be found inthe Searchline Excel Technical Handbook (p/n:2104M0506) and theSearchpoint Optima Plus Operating Instructions (p/n:2108M0501).3.3 Functional Gas Testing (Bump Test)Figure 3-11. Bump Test MenuWARNINGIt is recommended to bump test the sensors frequently to ensureproper operation.It is recommended that the detector is tested frequently to ensure thesystem is operating properly. Keep in mind different sensor types mayrequire more frequent maintenance depending on the environmentalconditions and gases present. The weatherproof cover has a spigotfor attaching tubing from a gas cylinder. This may be used for a simplefunctional (or bump) test of the sensor. However, this method may notbe suitable for all gas types and/or applications due to environmentalconditions. It is the responsibility of the user to ensure suitability ofthis method for each application.1. When bump gas is applied to the sensor, the bump test screendisplays the current reading of the sensor and the peak readingthat has occurred during the bump test.Current SensorReadingPeak ReadingFull Scale2.Alarm LevelsFigure 3-12.

If reading is still inaccurate replace the sensor (see Section 4.1).Once the Bump Test is completed successfully, the XNX will exit thecalibration procedure. Before returning to the Gas Calibration menuhowever, the user will be prompted to Exit and turn alarm and faultinhibit off, Exit and leave the XNX in inhibit mode, or do not exit.CautionExiting before the gas level has fallen below the level of Alarm 1 willcause the XNX to go into alarm.Figure 3-14.

XNX Universal TransmitterA HART ® ProtocolXNX Universal Transmitter Technical Manual A-1Release 4 (10/09)

XNX Universal TransmitterA.1 HART ® InterfaceEvery XNX gas detector can communicate using the HART protocol.The HART protocol is defined by the HART Communication Foundationat http://www.hartcomm.org. HART is unique among fieldbuses inthat the digital signal is superimposed on top of a traditional 4-20 mAcurrent loop. This provides the solid reliability of analog signaling withthe advanced diagnostic capability of a digital device.HART devices are usually connected as point-to-point networks.Additionally, the analog output of the XNX can be disabled to facilitateconstruction of multidrop all-digital HART networks.Control System orOther Host ApplicationInput/Output (I/O) SystemHandheld TerminalBarrierMultiplexerField DeviceHandheld TerminalControl Systemor Other Host ApplicationNote: Instrument power is provided by an interfaceor external power source that is not shown.Figure A-1. HART ® Point-to-Point ModeAppendix A - HART ® Protocol A-2Note: Instrument power is provided by an interfaceor external power source that is not shown.Figure A-2. HART ® Multi-Point ModeField DevicesIf HART is not needed the XNX may simply be used as a 4-20 mAtransmitter. Since the XNX is a slave, the internal modem will remain silentif no master signal is present. Additionally the HART signal is at too highof a frequency (1200 Hz) to interfere with analog control equipment.Another novel feature of HART networks is that two masters may bepresent. The primary master is generally a distributed control system(DCS), programmable logic controller (PLC), or a personal computer(PC). The secondary master can be a handheld terminal. The XNX hasbeen tested with the handheld Emerson 375 Field Communicator.The XNX device descriptor (DD) file provides HART masters withdata on the capabilities and features of the XNX gas detector. HARTterminals thus have a friendly, intuitive interface when connected tothe XNX. At press time, the XNX DD file was not yet available onthe HART Foundation website. A copy of the file is included on theDocumentation CD. This DD file may be installed in an Emerson 375Field Communicator using the 375 Easy Update Programming Utility.

XNX Universal TransmitterDuring manufacturing, Honeywell configures the 8-digit HART tag tothe XNX serial number. This may be used to confirm correct wiringfrom the XNX to the control system. The HART tag may be modifiedif desired. The fixed XNX serial number can also read over HART.For convenience, the XNX presents the HART signal on two interfaces.The 1200 Hz AC signal is capacitively coupled to the main 20 mAanalog output. This may be monitored at the control system or atany point along the 20 mA loop. Additionally, the optional local HARTinterface (P/N XNX-HIF) permits temporary connection of a HARTterminal to the XNX. This local HART port is transformer-coupledto the main 20 mA output. This port is intrinsically safe and polarityinsensitive. See Section 2.3.1 for more information.The internal HART modem functions as a high-impedance currentsource. Thus transferring the HART signal requires a certain minimumloop resistance between the slave and a low-impedance powersupply.Normally, this resistance is supplied by the control system and so neednot be explicitly added. However, special treatment is needed whenthe 20 mA output is not used and the local HART interface is needed.(An installer might choose to communicate using relays, Modbus, orFoundation Fieldbus instead.) In this case the supplied 510 Ohmresistor must be fitted to create an ‘artificial’ 20 mA loop. The resistorshould be connected between TB-1 terminal 1-3 and terminal 1-6.Additionally, S1 and S2 should be placed in ‘source’ configuration.This is shown schematically in Figure A-3.The digital HART interface provides all of the capabilities of the localuser interface. The XNX has been designed to use the portableEmerson 375 Field Communicator and with DevCom2000 software forMicrosoft Windows ® and Emerson AMS Intellegent Device Manager.Using HART, a service person can display information, test, calibrate,and configure.

XNX Universal TransmitterB Modbus ® ProtocolXNX Universal Transmitter Technical Manual B-1Release 4 (10/09)

XNX Universal TransmitterB.1 Modbus and the XNXThe XNX gas detector may be fitted with the optional Modbus interfacecard (P/N XNX-MB). Authoritative information on the Modbus protocolcan be found at www.modbus.org. The XNX supports Modbus/RTUover an RS-485 physical layer. The interface is isolated and includesa switchable 120 Ohm termination resistor. Baud rates from 1200 to38,400 are supported with 19,200 as the default.Most of the operations that are possible with the HART and local userinterfaces can also be performed using the Modbus interface. Thisincludes test, calibration and configuration operations. However, thisAppendix only describes how to monitor XNX status using Modbus.Information on more advanced operations is contained in technicalpublication 1998-0746.Some of the relevant Modbus holding registers are listed in the tablefollowing. Monitoring the XNX status is simpler than it looks – mostinstallations will read only the first five registers. (This is four data.)Note that the assignment of first eight registers (or six data) is identicalto the Honeywell Analytics XCD gas detector.Building an effective Modbus automatic gas detection system requireschecking for faults (using iFaultWarnNumber or iAlmFltLev) andchecking iMonitoringState to confirm that the XNX is not inhibitedor in calibration. The pseudo code example in Figure B-1 suggestscomputation that should be made in external automation equipment.See Section 2.3.4 for information on installing the optional Modbushardware. See Section 2.5.1 Configure Menu - Fieldbus Settingsfor information on setting the Modbus baud rate and address usingthe local user interface. See Section A.1.1 for information on settingthe Modbus parameters using the HART interface.if(((fCurrentConc < TLV) or (iAlmFltLev & 3 == 0))// low concentrationand((iFaultWarnNumber < 1000) or (iAlmFltLev & 64 == 0))// no faultand((iMonitoringState == 1) or (iMonitoringState == 7))// not inhibitedand((Transport layer SW indicates good Comm.)or(iHeartBeat changes every 5 seconds)) // Modbus link healthy) Then the area is safe.Figure B-1.
