2 Warnings

High off-scale readings may indicate an explosive concentration of gas.

Installation must be in accordance with the recognized standards of the appropriate authority in the country concerned.

Any work on the interior of the detector must be conducted only by trained personnel.

Ensure that local regulations and site procedures are followed when carrying out any work. Appropriate standards must be followed to maintain the overall certiication of the detector.

To reduce the risk of ignition of hazardous atmosphere, disconnect the equipment

from the supply circuit before opening the detector enclosure. Conduit runs must have a seal itting connected within 18 inches (45 cm) of the enclosures. Keep the assembly tightly closed during operation.

Never open the XNX enclosure under power unless the area is known to be non -hazardous.

The detector must be earthed/grounded for Intrinsic Safety, electrical safety, and to limit the effects of radio frequency interference. Earth/ground points are provided inside and outside the unit. EMI note for applications using shielded cable: Cable shield terminations must be made at the cable glands with suitable EMI type glands. Avoid terminating cable shields at the Earth ground lug inside the XNX enclosure. In cases where wiring is in pipe, a shielded cable is not required. The external terminal is only a supplemental bonding connection where local authorities permit or require such a connection.

Take care when handling EC sensor cells as they may contain corrosive solutions.

Do not tamper with or in any way disassemble the sensor cells.

Do not expose the transmitter or sensor cells to temperatures outside the recommended range.

Do not expose the sensor to organic solvents or lammable liquids.

At the end of their working lives, sensors must be disposed of in an environmentally safe manner. Disposal should be according to local waste management requirements and environmental legislation.

Alternatively, sensors may be securely packaged, clearly marked for environmental disposal, and returned to Honeywell Analytics.

Do NOT incinerate electrochemical cells as they may emit toxic fumes.

Verify all outputs, including display, after installation, after service events, and periodically to ensure the safety and integrity of the system.

Delays resulting from transmission errors between sensor and transmitter extend response times T90 by more than one-third. The period until fault indication is 10 seconds.

As some test gases are hazardous, exhaust the low housing outlet to a safe area. Do not use the XNX Universal Transmitter in oxygen-enriched atmospheres. (In oxygen-enriched atmospheres, the electrical safety is not given.)

XNX Universal Transmitter Quick Start Guide

Hazardous Locations instaLLation requirements (uL/csa/Fm)

To reduce the risk of ignition of hazardous atmospheres, conduit runs must have a pour gland installed within 18 inches (457mm) of enclosure.

All ¾ inch NPT conduit, stopping plugs and adapters must be installed with 5 ¼ threads (minimum) engaged to Maintain Explosion Proof rating.

The XNX Cover Assembly must be fully seated to enclosure 9 threads (minimum) to maintain Explosion Proof rating.

Stopping Plugs supplied (Honeywell Part Number 1226-0258) are approved for use ONLY with the XNX Universal Transmitter.

For units itted with the optional relay module: Relay contact ratings are 250 VAC 5A, 24 VDC 5A Resistive Loads Only.

Use copper conductors only, 60/75°C. Terminal block screws should be tightened to 4.5 lb/in maximum.

For models XNX-UT**-*****, refer to XNX control drawing 1226E0402 or, for models

XNX-BT**-*****, refer to control drawing 1226E0454 for additional information regarding IS function (local HART and EC personalities).

XNX Universal Transmitters carrying UL/CSA/FM approvals that are conigured

for devices measuring %LEL will not allow adjustments to the full scale value. The range is ixed at 100%.

Hazardous Locations instaLLation requirements (ateX)

Read and understand Technical Manual 1998M0738 before installation and use.

Use only Certiied M25 cable glands for installation.

Shielded armoured cable is required for CE compliance.

special conditions for safe use

The following applies to the HART Barrier intrinsically safe circuits: For

installations in which both the Ci and Li of the intrinsically safe apparatus exceeds 1% of the Co and Lo parameters of the associated apparatus (excluding the cable), then 50% of Co and Lo parameters are applicable and

shall not be exceeded, i.e. the Ci of the device plus the C of the cable must be less than or equal to 50% of the Co of the associated apparatus, and the Li of the device plus the L of the cable must be less than or equal to 50% of the Lo of the associated apparatus.

For circuits connected to the EC barrier in which the capacitance and inductance exceed 1% of the permitted values, then the maximum permitted capacitance is limited to 600nF for group IIC and 1uF for group IIIC.

The connection to the HART circuit shall be rated a minimum of IP 6X.

3 Mounting and Location of Detectors

caution

The location of the transmitters and sensors should be made in accordance with any relevant local and national legislation, standards or codes of practice. Always replace detectors with a detector of the same type. The detector should be mounted where the gas is most likely to be present. The following points should be noted when locating gas detectors.

Consider the possible damage caused by natural events e.g. rain or looding when locating detectors.

Consider ease of access for functional testing and servicing.

Consider how escaping gas may behave due to natural or forced air currents.

notes:

The placement of detectors should be determined following the advice of experts having specialist knowledge of gas dispersion, experts having knowledge of the process plant system and equipment involved, safety and engineering personnel. The agreement reached on the location of detectors should be recorded.

CSA certiication does not cover XNX EC cartridges or XNX EC cartridge remote mounting kit, daisy-chained XNX combustible gas transmitters or the

use of HART®, Modbus, or Foundation Fieldbus used for combustible gas performance. HART®, Modbus, or Foundation Fieldbus may be used only for

data collection or record keeping with regards to combustible gas detection.

FM approved conigurations (see the XNX Universal Transmitter Technical Manual, section 6.3 XNX Certiications by Part Number Series) also limit the

use of HART®, Modbus, or Foundation Fieldbus to use for diagnostics, data collection, or record keeping.

The XNX Universal Transmitter is certiied and designed for installation and use worldwide in hazardous areas.

3.1 Mounting the XNX Universal Transmitter

The XNX Universal Transmitter can be mounted in a number of different methods using the integral mounting tabs.

Using the mounting tabs, the XNX can be attached to:

Flat wall surface

Unistrut®

With the optional Pipe Mount kit, the XNX can be mounted to pipe of diameter 2 to 6 in (50 to 150mm).

A ceiling mount bracket kit (1226A0358) is also available.

notes:

Agency certiications require that EC and mV sensors face down. Optima sensors must be mounted horizontally.

4.1 General Wiring Considerations

For proper operation of the XNX Universal Transmitter and Sensor Technologies, consideration of wiring induced voltage drops, transient electrical noise and dissimilar Earth ground potentials is imperative in the design and installation of the system.

note:

EMI note for applications using shielded cable: Cable shield must provide 90% coverage of the wiring. Cable shield terminations must be made at the cable glands with suitable EMI-type glands. Avoid terminating cable shields at the Earth ground lug inside the XNX enclosure. Where wiring is in pipe, a shielded cable is not required.

Loading

Wiring for DC Power, 4-20mA Signal, remote wiring to sensors must be sized suficiently to provide suficient voltages for the line length and the loads that will

be used.

XNX Universal Transmitter Quick Start Guide

11

Isolation

Isolating power and signal carrying conductors is recommended.

Circuit Protection

Supply circuits must provide over current protection. Class 2 power supplies are required 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 for Searchpoint Optima Plus and Searchline Excel and 16 to 32 VDC dependent on the limitations of device for the generic 4-20mA input.

Loads

The use of High Inrush or Inductive loads may affect the performance of the XNX. For best reliability use resistive loads only.

4.2 Distance Considerations for Installation

Types of Installations

There are three basic types of installation: a single transmitter; multiple

transmitters connected to a single power source; and multiple transmitters connected in a daisy-chain coniguration.

Power and 4-20mA connections are made at TB-1 and are identical for the EC, IR, and mV personality boards. The minimum loop impedence is 200 ohms; the maximum is 500 ohms when the transmitter is supplied with an input of

16 volts. Failure to perform “Calibrate mA Output” or with loads outside the recommended values may result in diagnostic warning or fault messages.

The total load resistance recommended for the 4-20mA output should be kept lower than 500 ohms, including the resistance of the properly selected 4-20mA cable and input impedance of the equipment to be connected.

The XNX Universal Transmitter power consumption is dependent on the sensor and options for the speciic coniguration. For proper operation, the input

voltage must be maintained at 16 to 32 volts DC (for EC and mV transmitters) or 18 to 32 volts DC (for IR transmitters).

The table below deines the XNX typical and maximum power consumption based on coniguration:

HART® devices can operate in one of two conigurations: point-to-point or multi- drop.

HART® Communications

Point-to-Point Mode

In point-to-point mode, the 4–20 mA analog output is used to report concentration and the status of the transmitter to a dedicated channel of

the control system. Additionally, concentration, status, diagnostics, and coniguration are available digitally using the HART® protocol.

Multi-drop Mode

Multi-drop mode allows up to eight transmitters to interface with a single channel of a control system for non-safety-critical applications.

note:

Use a multi-drop connection for supervisory control installations that are widely spaced such as pipelines, custody transfer stations, and tank farms.

The minimum conductor size is 0.51mm diameter (#24 AWG) for cable runs less than 1,524m (5,000 ft) and 0.81mm diameter (#20 AWG) for longer runs.

Cable Length

Most installations are within the 3,000m (10,000 ft) theoretical limit for HART® communication. However, the electrical characteristics of the cable (mostly capacitance) and the combination of connected devices can affect the maximum allowable cable length of a HART® network. The following table shows the effect of cable capacitance and the number of network devices on cable length. The table is based on typical installations of HART® devices in non-IS environments, i.e. no miscellaneous series impedance.

note:

See Appendix A of the XNX Technical Manual for more information about the Local HART® Handheld.

4.5 Terminal Block Connections

Customer connections to the XNX are made via pluggable terminal blocks

secured to the back of the POD. The terminal blocks are keyed and polarized. A color coded label is afixed to assist in wiring when the block is removed from

the POD.

The terminals are suitable for use with 12 to 28 AWG or 0.8 to 2.5mm wire. Wire insulation must be stripped 5/16 (0.312) inches or 8mm. Tighten each terminal to a maximum of 4.5 in/lbs. Up to four terminal blocks will be supplied; each will be conigured with 2, 6, 9, or 10 positions.

Two terminal block jumpers are provided to provide an electrical connection without connecting to the Personality Board. Install the jumpers between pins 1 and 2 and between pins 3 and 4 to support multi-node wiring.

For user convenience, a second set of terminals has been provided to eliminate the need for a secondary junction box in multi-node systems. Two terminal block jumpers are provided which enable an electrical connection without connecting to the Personality Board. Install the jumpers between pins 1 and 2 and between pins 3 and 4 to support multi-node wiring.

note:

Pins 2 and 4 of terminal block TB1 have no internal connection on the

personality board. When used in conjunction with the terminal block jumpers, pins 2 and 4 can provide additional 4-20mA connections or

power feed for daisy-chained units.

caution

For biased sensors (e.g. Nitrogen Dioxide) remove the sensor stabilizer from the bottom of the sensor prior to installation.

Using Figure 11 as a guide, follow the procedure below:

1.Check that the label on the new sensor is the correct gas type.

2.Unscrew the weatherproof cover, loosen the retainer locking screw with the supplied hex key and unscrew the sensor retainer.

3.Plug in the new sensor taking care to align the sensor pins with the connector.

4.Reit the sensor retainer, tighten the locking screw with the supplied hex key and reit the weatherproof cover.

5.Countdown time of up to 180 seconds (dependent on sensor type) is displayed.

6.Acknowledgement of the gas type will be required before proceeding. For more information on setting gas type, see the XNX Technical Manual Section 2.51 Gas Selection.

7.After the sensor is installed and the gas type is conirmed, the Range, alarm levels and other important settings must be set; see appropriate section in Section 6 - Powering the XNX for the First Time.

8.Once the XNX has been conigured, calibrate the detector following the procedures in Section 8.1 - Calibration.

caution

Take care not to cut the cable too short. Once cut, additional lengths of cable cannot be added as this will invalidate the intrinsically safe certification. HA also recommends that a loop of cable is made at the junction box to allow slack for any future re-termination.

The enclosure of the remotely mounted sensor contains aluminum. Care must be taken to avoid ignition hazards due to impact or friction when installed in the Zone 1 location.

All cable entry devices and blanking elements shall be certified in type of explosion protection flameproof enclosure “Ex e”, suitable for the conditions of use and correctly installed.

4.7 mV Personality Wiring

XNX Universal Transmitter with the mV personality Board allows interface to a number of Honeywell Analytics’ Multi Purpose Detector (MPD) and ield proven

705 and Sensepoint devices.

caution

Check to ensure the XNX and mV Sensor has the appropriate approvals for your installation prior to commissioning.

Check the mV Sensor you are installing has compatible threads - 3/4 NPT or M25.

Connections from the mV sensor to the XNX are made via a single pluggable terminal block allowing ease of installation and service. HA recommends an 8” (203mm) service length for wiring be maintained. The wire colors for the connections for each sensor type are shown in the table on the following page. Be sure wires for 4-20mA outputs are routed away from sources of noise such as relay wires.

24

XNX Universal Transmitter Quick Start Guide

note

The black and red wires f.rom the MPD are not used with the XNX mV Personality Board. Ensure that they are properly isolated from live connections. DO NOT CUT.

caution

Be certain to dress the wires properly to ensure cabling does not contact switches 1-2 on the back of the POD. Do not force the POD into the enclosure as it may indicate an interference condition resulting in damage to the wiring, POD or switch settings.

To remotely mount the sensor, follow this procedure:

1.Install a junction box in the desired location. Allow suficient room for installation and calibration of the sensor. (MPD sensors must be installed with the sinter pointing down.)

2.Loosen the retainer locking screw on the transmitter with the supplied hex key.

3.Unscrew the transmitter’s weatherproof cover.

4.Run conduit or cable from one of the transmitter’s available conduit entries to the location of the remote junction box in accordance with local requirements. UL and CSA require a conduit pour itting within 45 cm (18 in.) of each enclosure.

5.Mount the remote sensor junction box. Allow enough room below it to it the sensor and the weatherproof cover.

6.Attach the conduit or cable to the remote junction box. The junction box provides a mounting base for the sensor and contains the associated electronic circuit.

28

XNX Universal Transmitter Quick Start Guide

note

The black and red wires from the MPD are not used with the XNX mV personality board. Ensure that they are properly isolated from live connections. DO NOT CUT.

caution

The enclosure of the remotely mounted 705 HT sensor contains aluminum. Care must be taken to avoid ignition hazards due to impact or friction when installed in the Zone 1 location.

All cable entry devices and blanking elements of the Junction Box shall be certiied in type of

explosion protection “Ex d” or “Ex e”, suitable for the conditions of use and correctly installed.

14.Attach and wire the sensor into the terminal box.

15.Fit the terminal box lid.

16.Fit the sensor retainer, tighten the locking screw and it the weatherproof cover (if required).

17.Calibrate the detector following the procedure in Section 8.1 - Calibration.

Ensure that wiring is adequately protected from mechanical failure in installation. Speciic shorted or open circuit conditions of wiring to the

MPD **I** sensors may result in full scale concentration readings prior to, or preventing the internal diagnostic routines from identifying the external installation fault.

4.8 IR Personality Wiring

The RS-485 digital communication is the primary interface in which the XNX transmitter reads gas concentration and sensor status from the Optima Plus/ Searchline Excel. If RS-485 communication fails, the Optima Plus/Searchline

Excel 4-20mA output becomes the primary source to read gas concentration.

Connections from the Searchpoint Optima Plus or Searchline Excel to the XNX are made via two pluggable terminal blocks allowing ease of installation and service (see Figure 20). HA recommends an 8” (203mm) service length for wiring be maintained.

Be sure wires for 4-20mA outputs are routed away from sources of noise such as relay wires The Searchpoint Optima Plus or Searchline Excel can be supplied in either Sink or Source mode operation and is typically labeled on the white wire exiting the Searchpoint Optima Plus or Searchline Excel. Use the table in Figure 20 to set S3 and S4 to the complimentary operating state of the equipment.

For more information see the Searchpoint Optima Plus Operating Instructions (2104M0508) or the Searchline Excel Technical Manual (2104M0506).

caution

Be certain to dress the wires properly to ensure cabling does not contact switches 1-4 on the back of the POD.

Do not force the POD into the enclosure as it may indicate an interference condition resulting in damage to the wiring, POD or switch settings.

XNX Universal Transmitter Quick Start Guide

29

Warning

Setting of S3 and S4 while power is applied or improperly set prior to applying power WILL PERMANENTLY DAMAGE the XNX. Both switches must be set in either Source or Sink prior to applying power.

Do not adjust switch settings while power is applied to the XNX; permanent damage WILL occur.

4.8.1Connecting a Searchpoint Optima Plus or Searchline Excel

Connections from the Searchpoint Optima Plus or Searchline Excel to the XNX are made via two pluggable terminal blocks allowing ease of installation and service (see Figure 18). HA recommends an 8” (203mm) service length for wiring be maintained.

The Searchpoint Optima Plus or Searchline Excel can be supplied in either Sink or Source mode operation and is typically labeled on the white wire exiting the Searchpoint Optima Plus or Searchline Excel. Use the table in Figure 18 to set S3 and S4 to the SAME output type that appears on the wire tag of the IR device.

note:

A second, black-handled screwdriver is included for use on terminal blocks 2 and 4. This tool is smaller than the magnetic wand and is designed to it into the terminal connections on TB2 and TB4.

For more information see the Searchpoint Optima Plus Operating Instructions (2104M0508) or the Searchline Excel Technical Manual (2104M0506).

Attaching the Searchpoint Optima Plus to the XNX Universal Transmitter

For M25 entries, insert the seal (P/N 1226-0410) into the proper cable/conduit opening then thread the lock nut (P/N 1226-0409) onto the Optima to the end

of the threads. Thread the Optima body into the XNX until the seal compresses and/or Optima bottoms out. Reverse until the semi-circular pattern of holes on

the front of the weather protection are on the bottom (see Figure 17) then tighten the lock nut to the XNX body.

Figure 17. Optima body orientation

The 3/4” NPT entries do not require the seal and locknut, the form of the threads

provide positive locking and sealing.

note:

When attaching the Searchpoint Optima Plus, be sure to coat the threads with an anti-seize compound to prevent corrosion.

XNX Universal Transmitter Quick Start Guide

Searchline Excel and Searchpoint Optima Plus Remote Installation

Junction Boxes are available for the Searchline Excel and Searchpoint Optima

Plus to facilitate remote mounting from the XNX Universal Transmitter. Junction boxes are available for installations requiring UL/CSA or ATEX approvals.

Consult the Searchline Excel Technical Handbook (2104M0506) or Searchpoint Optima Plus Operating Instructions (2104M0508) for speciics on remote

installations or contact your Honeywell Analytics representative for more information.

For remote mount installations, the maximum distance between the XNX Universal Transmitter and the Searchpoint Optima Plus unit is 33m (100 ft.), using 18 gauge wire.

Searchpoint Optima Plus or Searchline Excel Wiring Recommendations

When wiring the XNX and the Searchpoint Optima Plus or Searchline Excel for remote applications, the General Recommendations of the ANSI/TIA/EIA-485-A

standard must be adhered to with the following additions:

1.When mounting the Searchline Excel or Searchpoint Optima Plus, run wiring connections between each Excel or Optima and the XNX in a dedicated separate conduit.

2.Use 18 AWG twisted shielded cable for the RS485 connection between Excel or Optima and the XNX. Make sure that the shield of the cable is grounded to earth and XNX ground on one end ONLY.

3.Avoid running wiring near main cables or other high voltage equipment.

4.DO NOT APPLY 120 Ohm terminating resistors. These resistors are not required due to low data rates.

5.HA recommends that Excel or Optima and the XNX be wired to building ground. The system should be grounded at one point only.

instaLLation tip:

Always issue a soft reset after connecting the Optima and XNX for the irst time. The

soft reset is performed by accessing the XNX calibration menu.

note:

When the soft reset is initiated for the Optima IR Sensor, the RS-485 communication will be interrupted temporarily and faults F120 and/or F161 may be observed. RS-485 communication will be re-established

in a few minutes and the faults will be reset automatically in the Non- Latching Mode. The faults must be reset manually in the Latching Mode.

5 Options

5.1 Local HART® Interface

Available with any sensor technology or option, this option provides an external access to the HART® interface in the XNX. An IS barrier inside the XNX allows

the user to attach an external hand-held interrogator for programming and coniguration. The external interface is installed in the lower left cable/conduit

entry of the XNX and is intrinsically safe (IS).

5.2 Relays

The relay option (XNX-Relay) provides 3 form “C” (SPDT) normally/ open/ normally closed (NO/NC) contacts for alarm and fault indication. A remote reset

is provided to silence alarms. TB4 is provided as a connection to a user installed momentary switch to silence alarms remotely.

Exploring the functionality of the relay option board’s remote reset switch

The remote reset switch (designated TB-4 and labeled “Remote Reset SW”) is located on the relay option board. It provides a remote hardware-based reset of faults and alarms to the transmitter. In the event that direct access to the Local User (LUI) and HART® interfaces is not possible, alarms and faults from an XNX transmitter may be reset remotely using a switch.

The transmitter can be reset by activating a switch (Off-Mom). This will momentarily close the circuit between the two pins of TB4, providing the same functionality as a Reset Alarms & Faults command performed from the main screen of the LUI or the HART® interface.

note:

Relays are not available when the Modbus® or Foundation Fieldbus options are installed.

Wiring for the relays is through an available cable/conduit entry to a pluggable terminal block. See Figure 24 for the terminal block legend.

note:

A second, black-handled screwdriver is included for use on terminal blocks 2 and 4. This tool is smaller than the magnetic wand and is designed to it into the terminal connections on TB4.

6 Powering the XNX for the First Time

6.1XNX Units Configured for EC, mV, and IR (except Searchline Excel)

After mounting and wiring the XNX, the plug in sensor should be itted (if equipped) and the installation visually and electrically tested as below.

Warning

Prior to carrying out any work, ensure local and site procedures are followed. Ensure that the associated control panel is inhibited so as to prevent false alarms. Minimum and maximum controller alarm levels should not be set at less than 10% or greater than 90% of the full scale range of the detector. CSA and FM agency limits are 60% LEL or 0.6mg/m3.

caution

The following procedure should be followed carefully and only performed by suitably trained personnel.

1.Check that the transmitter is wired correctly according to this manual and the associated control equipment manual.

2.If equipped, unscrew the weatherproof cover, loosen the sensor retainer locking screw and unscrew the retainer.

3.Plug in the sensor cartridge taking care to align the sensor pins with the connector holes in the PCB.

caution

For toxic sensors, remove the shorting clip from the bottom of the sensor prior to installation. For O2 sensors, there is no shorting clip provided.

4.Reit the sensor retainer, tighten the locking screw and reit the weatherproof cover.

note:

Before replacing the cover on the transmitter housing, coat the threads with anti-seize compound to prevent corrosion buildup.

Also inspect the cover o-ring for cracking or any other defect that might compromise the integrity of the seal. If it is damaged, replace with the o-ring supplied in the accessory kit.

5.Apply power to the XNX which will in turn provide power to the detector.

6.The detector output will be forced to 3mA (default fault/inhibit).

7.The XNX display will enter a start up routine displaying the initialization screen, then the transmitter loads its operating system, data from the sensor and checks if it is the same type transmitter and sensor software version numbers, gas type, the detection range and span calibration gas level, estimated time to next calibration due, and self test result. The boot-up procedure takes approximately 45 seconds. The LCD and LED test is performed in the initialization after powering on. All LCD pixels and LEDs (red,

XNX Universal Transmitter Quick Start Guide

39

green, and yellow) are turned on for 1.5 seconds. The LCD then goes blank and the LEDs turn off.

Figure 27. XNX Initialization and General Status screens

note:

In the inal stages of boot-up, warnings and faults may be observed until the user performs the proper coniguration, calibration, and reset activities described in the following sections. See Sections 11 and 12 for

descriptions of warnings and faults.

8.Once the General Status screen appears, the transmitter and detector are in normal ‘monitoring’ mode.

note:

Calibration of sensors attached to the XNX is mandatory before the detector can be used for gas monitoring. Refer to Section 6.1 -

Calibration for the proper procedure. For EC and mV personalities, perform Accept New Sensor Type before calibrating the sensor.

6.2 XNX IR Units Configured for Searchline Excel

When powering the XNX itted to the Searchline Excel, the following procedure

must be followed to assure proper installation.

caution

The following procedure should be followed carefully and only performed by suitably trained personnel

1.Check that the transmitter is wired correctly according to this manual and the associated control equipment manual.

2.Apply power to the XNX which will in turn provide power to the detector.

3.The detector output will be forced to 3mA (default fault/inhibit).

4.The XNX display will enter a start up routine as described in Section 6.1.7

Figure 28. XNX Initialization and General Status screens

XNX Universal Transmitter Quick Start Guide

note:

In the inal stages of boot-up, warnings and faults may be observed until the user performs the proper coniguration, calibration, and reset activities described in the following sections. See Sections 11 and 12 for

descriptions of warnings and faults.

5.When the XNX completes boot-up, perform a soft reset on the Excel from the Calibration Menu.

6.Set the Path Length for the application, then align the transmitter and receiver with Align Excel.

7.Once the alignment is complete, a Zero Calibration must be performed on the Excel to complete the commissioning process. (See the Searchline Excel Technical Manual for calibration information P/N 2104M0506).

8.Reset any faults displayed on the XNX display. The XNX and Excel are now ready to monitor.

XNX Remote Calibration for MPD Sensors

In addition to functional gas testing to ensure the system is operating properly, remote calibration for the MPD CB1catalytic combustible sensor and MPD IV1 and MPD IF1 infrared combustible sensors can be performed provided the fol- lowing requirements are met:

Remote sensor is installed in an indoor environment

Internal air velocity does not exceed 0.5 m/s

Weather housing part number 0200-A-1640 is installed on the sensor housing

A 1 LPM regulator is used for calibration gas delivery

The remote calibration procedure should be performed in accordance with

Section 6.1 with the exception of the weather guard, part number 0200-A- 1640, which should be used instead of the regular low housing, part number

1226A0411.

Honeywell Analytics recommends MPD sensor calibration at a maximum interval of 180 days (the XNX default value). This value can be reprogrammed in accord-

ance with site procedures to assure the highest level of safety. Correct opera- tion of each sensor should be conirmed before each use by calibration with a certiied test gas of known concentration. In addition, the pellistors used in lammable gas sensors can suffer from a loss of sensitivity when in the presence of poisons or inhibitors, e.g., silicones, sulides, chlorine, lead, or halogenated

hydrocarbons.

1Special states that inhibit the transmitter from detecting gas are indicated as 2 mA on analog outputs.

8.1 Calibration

Warning

Do not use the XNX Universal Transmitter in oxygen-enriched atmospheres. Concentrations displayed will be adversely affected by oxygen depletion.

caution

The calibration procedure should only be performed by qualiied personnel.

note:

The default calibration values for the “Calibration Required” diagnostic

vary based on sensor type. This value can be reprogrammed in

accordance with site requirements to ensure the highest level of safety. Correct operation of each sensor/detector should be conirmed using calibration with a certiied test gas of known concentration before

commissioning. See Section 9 - Sensor Data for calibration gas speciications.

8.1.1 Calibration Procedure

note:

Follow the speciic procedure outlined in the Operating Manual for each

sensing device. The Zero Calibration procedure should be performed prior to the Span Calibration procedure.

1.If using compressed gas cylinder, attach the calibration gas low housing onto the bottom of the sensor and apply the gas.

2.Access the calibration mode. The Gas Calibration menu is for both Zero and Span Calibration.

6.Select then apply the target gas. As the sensor detects the gas and the concentration increases, the sensor reading values in the display will change to relect the changing concentration.

7.When the concentration values stabilize, the gas concentration as read by the installed sensor is stable. At this time, the gas readings are taken by the sensor. The Span Calibration process also determines whether the sensor is within the proper range to accurately detect the target gas.

8.When the sensor has completed the calibration and the span algorithms have determined 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.

XNX Universal Transmitter Quick Start Guide

Figure 48. Exiting options

Warning

While XNX is in Inhibit Mode, alarms are silenced. This will prevent an actual gas event from being reported. Inhibit Mode must be reset after testing or maintenance activities.

8.1.2 Zero and Span Calibration for XNX EC Sensors

caution

Before initial calibration, allow the detector to stabilize for 30 minutes after applying power. When in zero and span calibration mode, the current output from the detector is inhibited (default 3mA) to avoid false alarms.

It is recommended for most sticky gases (i.e.: HCl, Cl2) the tubing should be PTFE with short pieces

of rubber tube to make the inal connection due to the inlexibility of PTFE. This minimizes adhesion

of the gas to the tube surface and allows for more accurate measurement.

Recalibration is recommended if the temperature of local environment has varied by more than +/-15 degrees C from the temperature of calibration.

EN performance standards require 10 minutes stabilization time for application of zero and span gas for performance-approved EC, mV, and IR sensors prior to calibration..

To calibrate the detector, use an appropriate span gas cylinder, low regulator set to 300-375mL/min, tubing, magnet and calibration gas low housing. A

compressed gas cylinder (20.9%Vol oxygen) should be used to perform the zero calibration if the area where the detector is located contains any residual amount of the target gas. If no residual gas is present then the background air can be used to perform the zero calibration. Contact your HA representative for details of suitable calibration kits.

To calibrate the detector follow the procedure in Section 8.1.1.

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 a compressed air cylinder (20.9%Vol oxygen).

See section 6.3.2 of the XNX Technical Manual for other EC sensors.

8.1.3 Zero and Span Calibration of XNX EC Hydrogen Sulfide (H2S) Sensors

caution

Before initial calibration, allow the detector to stabilize for 30 minutes after applying power. When in zero and span calibration mode, the current output from the detector is inhibited (default 3mA) to avoid false alarms.

Recalibration is recommended if the temperature of local environment has varied by more than +/-15 degrees C from the temperature of calibration.

Hydrogen Sulide sensors can be affected by extreme humidity changes. A

XNX Universal Transmitter Quick Start Guide

49

sudden increase in ambient humidity can result in a short-term positive drift in the instrument’s reading. A sudden decrease in ambient humidity can result in a short- term negative drift in the instrument’s reading. These are most likely to be noticed during calibration with dry or cylinder gas.

When calibrating Hydrogen Sulide cartridges the following should be taken into account while following the procedure in Section 8.1.1:

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 applied to the sensor immediately after the zeroing procedure. Do not allow the sensor to return to ambient air conditions.

8.1.4 XNX EC Sensor Operational Life

Typical life of a toxic gas sensor is dependent on the application, frequency

and amount of gas exposure. Under normal conditions, with a 3 month visual inspection and 6 month test/re-calibration, the toxic sensor has an expected life

equal to or greater than the lifetime as listed below:

12 months for Ammonia and Hydrogen Fluoride sensors. (See Ammonia note below.)

24 months for Chlorine Dioxide, Oxygen, and other toxic sensors.

caution

Oxygen deicient atmospheres (less than 6%V/V) may result in inaccuracy of reading and

performance.

note:

Ammonia electrochemical cells are reliable and suitable for applications where

no background concentration of ammonia exists. Under these conditions the cells are expected to operate for 12 to 24 months.

These ammonia cells are of the consumptive type. Their operating life can be adversely affected by continuous or excessive exposure to ammonia, or by prolonged exposure to high temperatures and moisture.

To ensure continued detection availability, it is recommended that the detectors are regularly bump tested and a relevant cell replacement program be implemented.

8.1.5 Zero and Span Calibration for MPD Sensors

caution

Extended or frequent exposure to elevated concentrations of combustible gases may affect sensor sensitivity. Verify sensor performance by frequent calibration.

caution

Before initial calibration, allow the detector to stabilize for 30 minutes after applying power. When in zero and span calibration mode, the current output from the detector is inhibited (default 3mA) to avoid false alarms.

50

XNX Universal Transmitter Quick Start Guide

This section describes how to calibrate MPD lammable sensors itted to the

XNX. The calibration adjustments are made on the XNX’s display and gassing is performed at the sensor. This may be locally or remotely located.

The following equipment is required:

Flow Housing (Part No: 1226A0411)

Test gas

Regulator

note:

Zero gas and Span gas should be at roughly the same humidity levels to avoid erroneous cell responses.

1.At the MPD, remove the Weatherproof Cap if equipped.

2.Fit the Flow Adaptor onto the MPD.

Figure 49. Flow adaptor

Reverse the cap removal procedure. The following diagram shows the Flow Adaptor accessory itted to the MPD.

Figure 50. MPD with low adaptor

note

The Gas Calibration menu is for both Zero and Span Calibration.

3.Connect the Flow Adaptor (using either gas pipe) to the regulated cylinder containing a known concentration of the target gas at approximately the sensor alarm point (e.g. 50% LEL Methane in air).

Warning

As some test gases may be hazardous, the Flow Housing outlet should exhaust to a safe area.

4.Follow the procedure in Section 8.1 for both Zero and Span calibrations.

XNX Universal Transmitter Quick Start Guide

51

5.Apply the target gas to the sensor. Pass the gas through the Flow Adaptor at a rate of 0.5 l/m ±0.2 l/m.

note:

Sensors should be calibrated at concentrations representative of those to be measured. It is always recommended that the sensor is calibrated with the target gas it is to detect.

caution

Where the user calibrates any sensor using a different gas, responsibility for identifying and recording calibration rests with the user. Refer to the local regulations where appropriate.

6.Ensure that the sensor and the vicinity around it is clear all traces of the calibration gas before continuing. This is to avoid triggering spurious alarms. If calibration fails at any point, discard the cartridge and replace with a new one.

7.Remove the test equipment, reit the weatherproof cap to the sensor (if previously removed for the test) and return the system to normal operation.

8.1.6MPD Flammable Sensor

The pellistors used in the lammable gas sensor can suffer from a loss of sensitivity when in the presence of poisons or inhibitors, e.g., siliconse, sulides,

chlorine, lead, or halogenated hydrocarbons. The pellistors are poison resistant to maximixe the operational llife of the lammable sensor.

8.1.7 Cross Calibration procedure for MPD-CB1

caution

Where the user calibrates any sensor using a different gas, responsibility for identifying and recording calibration rests with the user. Refer to the local regulations where appropriate.

When the MPD-CB1 Combustible LEL sensor is to be calibrated with a gas which is different from the gas or vapor to be detected, the following cross calibration procedure should be followed:

note

The irst table on page 49 lists the gases according to the reaction they produce at a given detector.

An eight star (8*) gas produces the highest output, while a one star (1*) gas produces the lowest output. (These are not applicable at ppm levels.)

note

Since combustible sensors require oxygen for correct operation, a

mixture of gas in air should be used for calibration purposes. Assuming average performance of the sensor, the sensitivity information in Tables 1 to 3 is normally accurate to +20%.

EXAMPLE

If target gas to be detected is Butane and the calibration gas available is Methane (50% LEL):

1.Look up the star rating for each gas in the irst table on page 51: Butane 4* and Methane 6*.

2.Check the meter settings for 50% LEL calibration gas in the second table: 78.

3.The meter should therefore be set to 78% to give an accurate reading for Butane using 50% LEL Methane as a calibration gas.

note

It is important to calibrate the sensor at the approximate alarm levels to allow for non-linearity of the sensors at gas concentrations above 80% LEL.

8.2 Functional Gas Testing (Bump Test)

Warning

Honeywell recommends periodic bump tests (every 30 days or in accordance with customer site procedures) to the sensor to insure proper operation and compliance with the Functional Safety rating of the installation.

Warning

Exposure to desensitizing or contaminating substances or concentrations causing operation of any alarm may affect sensor sensitivity. Following such events, it is recommended to verify sensor performance by performing a functional gas test (bump test).

caution

The calibration procedure should be performed only by qualiied personnel. The appropriate precautions with cylinders of lammable and toxic gases.

It is recommended that the detector is tested frequently to ensure the system is operating properly. Keep in mind different sensor types may require more frequent maintenance depending on the environmental conditions and gases present. The weatherproof cover has a spigot for attaching tubing from a gas

cylinder. This may be used for a simple functional (or bump) test of the sensor. However, this method may not be suitable for all gas types and/or applications

due to environmental conditions. It is the responsibility of the user to ensure suitability of this method for each application.

1.When bump gas is applied to the sensor, the bump test screen displays the current reading of the sensor and the peak reading that has occurred during the bump test.

Footnotes:

1.1. XNXXSC1FM accuracy over temperature <±10% of reading 20°C/68°F to 55°C/131°F, <±20% of reading 20°C/68°F to -10°C/14°F, <±30% of reading -10°C/14F to -20°C/-4°F. Recalibration is recommended if the temperature of the local environment has varied by more than -30°C.

Notes:

Performance igures are measured by test units calibrated at 50% of full scale, at ambient conditions of 20°C, 50% RH, with the EC weatherproof cover attached

IP rating of FM Cartridges is IP63.

Barometric pressure effects on the O2 sensor: The output from the O2 sensor has pressure effects of <0.1% change of output per % change in pressure. When the barometric pressure changes by ±20% the output from the O2 sensor changes <±0.4%Vol. However, the oxygen sensor shows transient behavior when subjected to a rapid change in ambient pressure due to either weather or altitude. For example, a 10KPa instantaneous positive pressure step change may cause an overscale alarm condition for a period of about 12

seconds.

Operating the XNX EC sensor at extended temperature ranges for a prolonged time period exceeding 12 hours my cause deterioration in the sensor performance and shorten sensor life. Extended temperature range for XNX EC sensors is -40°C ot -20°C.

Response times may increase at lower temperatures.

Footnote:

1. Accuracy of reading at default Alarm 1 concentration (typically 10% FS or defined minimum alarm level setting, whichever is greater) when operated at default full scale.

Note:

Sensor drift between LDL and negative drift fault limits (typcially > negative zero variation) appear as 0 on the display and outputs of the device.

Long-term drift: XNXXSC1SS <5%/year, XNXXSO1SS <4%/year, XNXXSH1SS and XNXXSH2SS <2%/month. Performance igures are measured by test units calibrated at 50% of full scale, at ambient conditions of 20°C, 50% RH, with the EC weatherproof cover attached.

Operating the XNX EC sensor at extended temperature ranges for a prolonged time period exceeding 12 hours may cause deterioration in sensor performance and shorten sensor life. Extended temperature ranges for XNX EC sensor cartridges are -40°C to -20°C.

Barometric pressure effects on the O2 sensor: The output from the O2 sensor has pressure effects of <0.1% change of output per % change in pressure. When the barometric pressure changes by ±20%, the output from the O2 sensor changes <±0.4%Vol. However, the oxygen sensor shows transient behavior when subjected to a rapid change in ambient pressure due to either weather or altitude. For example, a 10KPa instantaneous positive pressure step change may cause an overscale alarm condition for a period of about 12 seconds.

Footnotes (see table on previous page):

1.Accuracy of reading at default Alarm 1 concentration (typically 10%FS or defined minimum alarm level setting, whichever greater) when operated at default full scale.

2.System conditioning may be required to achieve stated results. Contact Honeywell Analytics for details.

3.Measured using calibration flow housing at calibration flow rate (300-375 ml/min) with dry gas.

Notes (see table on previous page):

Data taken at ambient conditions of 20°C, 50% RH.

Data represents typical values of freshly calibrated sensors without optional accessories attached.

Performance igures are measured by test units calibrated at 50% of full scale.

Standard temperature range for XNX EC Sensors is -20°C to +55°C; ATEX, IECEx.

Extended temperature ranges for the XNX EC Sensors are -40°C to -20°C

Accuracy between the temperatures of -40°C and -20°C is ±30% at the applied gas concentration.

Operating the XNX EC Sensors at extended temperature ranges for a prolonged time period exceeding 12 hours may cause deterioration in sensor performance and shorter sensor life.

Barometric pressure effects on the O2 sensor: The output from the O2 sensor has pressure effects of <0.1% change of output per % change in pressure. When the barometric pressure changes by ±20% the output from the O2 sensor changes <±0.4%Vol. However, the oxygen sensor shows transient behavior when subjected to a rapid change in ambient pressure due to either weather or altitude. For example, a 10KPa instantaneous positive pressure step change may cause an overscale alarm condition for a period of about 12

seconds.

Recalibration is recommended if the temperature of local environment has varied by more than ±15°C from the temperature of calibration.

Response times may increase at lower temperatures.

Contact Honeywell Analytics for any additional data or details.
