1 Mounting and Location of Detectors

cAutIoNThe 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.

When locating detectors consider the possible damage caused by 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 forced air •currents.

NoteThe 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.

1�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.Integral Mounting Lugs

cAutIoNBefore wiring the XNX, confirm the correct personality boards and options are installed.

2�1 General Wiring ConsiderationsFor 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.

Loading

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

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.

2�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” configuration.

Power Source Selection

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 watts•

Wire Selection

The type of wire used for connections has an effect on the distance of the installation. This is because some of the voltage is lost in the wire on the way to the transmitter.

Distance Chart for Single Transmitter Distances

For installations that have dedicated wiring between the transmitter and the power supply, use the following chart. These distances assume stranded wire is used.

NoteIf multiple transmitters are using the same power supply, make sure the power supply wattage rating is high enough to power all transmitters simultaneously.

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 14. 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 below 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).

cAutIoNBe 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.

WARNINGSetting 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.


2�8�1 Connecting a Searchpoint Optima Plus or Searchline ExcelConnections 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 14). HA recommends an 8” 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 14 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 fit 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 then 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 below) then tighten the lock nut to the XNX body.

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.

2�8�2 Connecting Generic mA DeviceIR personality type provides for a Generic mA input under sensor type configuration. The XNX can be used to convert the mA input to be read over HART protocol or optional Modbus and set optional relays (if equipped). Additional configuration of gas type and unit ID for reporting is required (see Gas Selection). For Generic mA devices, input values below 3mA will generate Fault 155.

Use the following schematics to set S3 and S4 to the same output type that appears on the wire tag of the mA device.

3 Options

3�1 Local HART® Handheld

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 configuration. The external interface is installed in the lower left cable/conduit entry of the XNX and is intrinsically safe (IS).

Intrinsically Safe Barrierfor HART Interface

HART Handheld InterfaceConnector w/Protective Cap

Figure 21. XNX Universal Transmitter with HART® Interface IS Barrier installed

HART® devices can operate in one of two configurations - point-to-point or multidrop.

Point-to-Point Mode

In point-to-point mode, the 4–20 mA signal is used to communicate one process variable, while additional process variables, configuration parameters, and other device data are transferred digitally via HART® protocol. The 4–20 mA analog signal is not affected by the HART® signal.

Multidrop Mode

The 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 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 distances.

Cable Length

Most installations are well 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 table in Figure 22 shows the affect 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.

3�2 Relays

The relay option (XNX-Relay) provides 3 form “C” SPCO contacts for alarm and fault indication. TB4 is provided as a connection to a user installed momentary switch to silence alarms remotely.

Note:This option is not available with the Modbus® option.

Wiring for the relays is through an available cable/conduit entry to a pluggable terminal block. See Figure 4 for the terminal block legend.

6�1 Calibration

cAutIoNThe calibration procedure should only be performed by qualified personnel.

Note:Honeywell Analytics recommends that the maximum calibration interval be 30 days or in accordance with customer site procedures to assure the highest level of safety. Correct operation of each sensor/detector should be confirmed with test gas of known concentration before each use.

See Section 7 - XNX Electrochemical Sensor Data for Calibration Gas specifications.

6�1�1 Calibration ProcedureNote:

Follow the specific procedure outlined in the Operating Manual for each sensing device.

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

Access the calibration mode. 2.

Once the Zero and Span calibrations are completed successfully, the XNX will exit the calibration procedure. Before returning to the Gas Calibration menu however, the user will be prompted to Exit and turn alarm and fault inhibit off, Exit and leave the XNX in inhibit mode, or do not exit.

WARNINGWhile 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.


6�1�2 Zero and Span Calibration for XNX EC Sensors

cAutIoNBefore 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 final connection due to the inflexibility 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.

To calibrate the detector, use an appropriate span gas cylinder, flow regulator set to 300-375mL/min, tubing, magnet and calibration gas flow 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 Honeywell Analytics representative for details of suitable calibration kits.

To calibrate the detector follow the procedure in Section 6.

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).

6�1�3 Zero and Span Calibration of XNX EC Hydrogen Sulfide (H2S) Sensors

cAutIoNBefore 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 Sulfide sensors can be affected by extreme humidity changes. A 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 Sulfide cartridges the following should be taken into account while following the procedure in Section 6.1.1:

To zero the sensor, use a compressed gas cylinder of 20.9%Vol oxygen 1. (not Nitrogen). Do not use background air.

If a span calibration is to be performed, the span calibration gas should be applied 2. to the sensor immediately after the zeroing procedure. Do not allow the sensor to return to ambient air conditions.


6�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 (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:

18 months for Chlorine and Chlorine Dioxide sensors.•

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

24 months for Oxygen and other toxic sensors.•

cAutIoNOxygen deficient 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.

6�1�5 Zero and Span Calibration for MPD Sensors

cAutIoNBefore 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.

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 performed at the sensor (this may be locally or remotely located).

The following equipment is required:

Flow Housing (Part No: 02000-A-3120)•

Test gas•

Regulator •

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

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

Fit the Flow Adaptor onto the MPD.2.


Figure 45. Flow Adaptor

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

Figure 46. MPD with Flow AdaptorNote

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

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

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

Follow the procedure in Section 7.1 for both Zero and Span calibrations.4.

Apply the target gas to the sensor. Pass the gas through the flow housing 5. at a rate of between 0.7l/m and 1.0l/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.

cAutIoNWhere 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.


Ensure that the sensor and the vicinity around it is clear all traces of the 6. 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.

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

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 to the gas or vapor to be detected, the following cross calibration procedure should be followed:

Note Table 1 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.)

Gas Star Rating Gas Star Rating

Acetone 4* Hexane 3*

Ammonia 7* Hydrogen 6*

Benzene 3* Methane 6*

Butanone 3* Methanol 5*

Butane 4* MIBK 3*

Butyl acetate 1* Octane 3*

Butyl acrylate 1* Pentane 3*

Cyclohexane 3* Propane 5*

Cyclohexanone <1* Propan-2-ol 4*

Diethyl ether 4* Styrene 2*

Ethane 6* Tetra hydrafuran 4*

Ethanol 5* Toluene 3*

Ethyl acetate 3* Triethylamine 3*

Ethylene 5* Xylene 2*

Heptane 3* Table 1. Star Rating of Gases

To cross calibrate the MPD-CB1 combustible gas sensor:

Obtain the star rating for both the test gas and the gas to be detected from 1. Table 1.

These values may then be used in Table 2 to obtain the required meter 2. setting when a 50% LEL test gas is applied to the detector.

NoteThese settings must only be used with a calibration gas concentration of 50% LEL.

If a sensor is to be used to detect a gas other than that for which it was 3. calibrated, the required correction factor may be obtained from Table 3. The meter reading should be multiplied by this number in order to obtain the true gas concentration.

1* 0.21 0.26 0.32 0.39 0.49 0.62 0.78 1.00Table 3. Meter Multiplication Factors

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):

Look up the star rating for each gas in Table 1: 1. Butane 4* and Methane 6*Check the meter settings for 50% LEL calibration gas in Table 2: 2. 78The meter should therefore be set to 78% to give an accurate reading for 3. 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.

6�1�7 Calibrating the 705/705HT

For more complete calibration and configuration information, see the Type 705 Operating Instructions (p/n:00705M5002).

6�1�8 Calibrating the Sensepoint/Sensepoint HT

For more complete calibration and configuration information, see the Sieger Sensepoint Technical Handbook (p/n:2106M0502).

6�1�9 Calibrating the Searchline Excel and Searchpoint Optima Plus

Complete calibration and configuration information can be found in the Searchline Excel Technical Handbook (p/n:2104M0506) and the Searchpoint Optima Plus Operating 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 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.

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

Alarm Levels

Current SensorReading

Figure 47. Bump Test Screen

If the difference between reading and applied gas concentration is outside 2. the acceptable limits for the application follow the procedures for zeroing and calibrating the detector (see Section 7.1).

If reading is still inaccurate replace the sensor.3.
