XNX Universal Transmitter Quick Start Guide6
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.
XNX Universal Transmitter Quick Start Guide10
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.

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.

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.
XNX Universal Transmitter Quick Start Guide42
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.
XNX Universal Transmitter Quick Start Guide 43
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.
XNX Universal Transmitter Quick Start Guide44
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.
XNX Universal Transmitter Quick Start Guide 45
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.
6�1�6 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 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*

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.
XNX Universal Transmitter Quick Start Guide 47
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�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.
