Common Questions
10 totalHow do I initialize and power up an XNX unit for the first time?
After mounting and wiring, the sensor should be fitted (if equipped), and installation visually tested. Apply power to the XNX, which will force the detector output to 2mA (default/inhibit) while going through startup routines displaying initialization and general status screens. This process lasts approximately 45 seconds before entering normal monitoring mode.
What is the procedure for powering up an XNX unit with a Searchline Excel sensor?
First, ensure proper wiring according to the manual and control equipment guide. After applying power to the XNX transmitter, it forces the detector output to 2mA (default/inhibit) during startup routines displayed on initialization screens. Complete the setup by performing a soft reset from the Calibration Menu.
What should I do if my XNX unit shows warning or fault messages after powering it up for the first time?
In final stages of startup, warnings and faults may appear until proper configuration and calibration are performed. These activities include resetting any displayed faults on the General Status screen by following subsequent sections of the guide.
How do I perform calibration for XNX Universal Transmitter sensors?
To perform zero and span calibrations, access the Gas Calibration menu. Apply appropriate calibration gas cylinder with flow regulator tubing to perform a zero calibration first, followed by span calibration if needed. A successful calibration sequence will show Zero and Span Passed screens.
What special precautions are there for calibrating H2S sensors in XNX?
Prior to the initial zeroing, allow the detector to stabilize for 30 minutes after applying power. Use a compressed gas cylinder of 20.9%Vol oxygen (not nitrogen) and immediately proceed with span calibration without letting the sensor return to ambient air.
How do I perform zero only calibration on EtO sensors in XNX?
For zero-only calibration in clean ambient air or clean humidified air (not nitrogen), apply clean dry air for 5 minutes, then follow the detector's instructions to confirm zero calibration. No span calibration is required.

XNX Universal Transmitter Quick Start Guide 8 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.
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 certification 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 configurations (see the XNX Universal Transmitter Technical Manual, section 6.3 XNX Certifications 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 certified 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:Notes:

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 sufficiently to provide sufficient voltages for the line length and the loads that will be used.
XNX Universal Transmitter Quick Start Guide 12 Isolation Isolating power and signal carrying conductors is recommended. Circuit Protection Supply circuits must provide over current protection. 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 configuration.

XNX Universal Transmitter Quick Start Guide 18 The XNX Universal Transmitter power consumption is dependent on the sensor and options for the specific configuration. For proper operation, the input voltage must be maintained etween 16 and 32 volts DC (for EC and mV transmitters) or 18 and 32 volts DC (for IR transmitters). The table below defines the XNX typical and maximum power consumption based on configuration: Configuration Max Power Inrush

Additionally, concentration, status, diagnostics, and configuration are available 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.

XNX Universal Transmitter Quick Start Guide 36 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 configuration. The external interface is installed in the lower left cable/conduit entry of the XNX and is intrinsically safe (IS). Intrinsically Safe Barrier for HART Interface HART Handheld Interface Connector w/Protective Cap Figure 23. XNX Universal Transmitter with HART® interface IS barrier installed 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. Remote reset switch feature 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 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 momentary switch. 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 Local User 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 fit into the terminal connections on TB4.

XNX Universal Transmitter Quick Start Guide 47 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 qualified 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 confirmed using calibration with a certified test gas of known concentration before commissioning. See Section 9 - Sensor Data for calibration gas specifications. 8.1.1 Calibration ProcedureNote:
Follow the specific procedure outlined in the Operating Manual for each sensing device. The Zero Calibration procedure should be performed prior to the Span Calibration procedure.
XNX Universal Transmitter Quick Start Guide 48
Note:
If a Span Calibration is not required, select the ✖ to skip the Span Calibration and return to the Calibration menu.switches to increment or decrement the values. Select ✓ to accept the new value and move to the next digit. Continue until all 3 digits have been selected. Sensor Reading at Current Settings Calibration Gas Concentration Figure 46. Span Calibration screen
XNX Universal Transmitter Quick Start Guide 49 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 with inhibit off, exit with inhibit on, or not exit.
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 of 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 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. 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, 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 representative for details of suitable calibration kits. To calibrate the detector follow the general procedure in Section 8.1.1. Refer to the following sections for special calibration requirements for specific sensors.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).
XNX Universal Transmitter Quick Start Guide 50 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 2mA) 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 8.1.1:
Warning
Long-term exposure (>20 minutes) to concentrations exceediing the full-scale range of the H2S sensor Type 2 can cause it to lose sensitivity. The measured value may then decrease even though high levels of toxic gas are still present. If such conditions can occur, set the control unit to latch at overrange. In standalone operation, set alarms to latching. When resetting the overrange or alarm, verify the correct operation of the transmitter. Before re-calibrating the transmitter, verify the absence of gas. Hydrogen Cyanide (HCN) The span calibration can be performed using HCN from a cylinder at a suitable concentration. Adjust the span calibration set point in the instrument to match that of the concentration actually applied. Pay special attention to the following points:
XNX Universal Transmitter Quick Start Guide 51 Fluorine (F2) The calibration is performed using 2 ppm (nominal) chlorine (Cl2). Honeywell Analytics strongly recommends that a suitable Cl2 generator be used for this operation. Adjust the span calibration set point in the instrument to match that of the concentration actually applied. Pay special attention to the following points:
Note:
Ethylene oxide sensors are supplied on a transportation board in order to keep the cell biased at the correct level. Once removed from the transportation board the sensor should be fitted to the detector as soon as possible. If the sensor is not fitted to the transportation board or a powered detector, its bias will decay and the sensor will take up to 24 hours to recover. During this period the sensor will not function as a gas detector, reporting a gas reading above full scale. When calibrating ethylene oxide sensors, the following should be taken into account:
XNX Universal Transmitter Quick Start Guide 52
XNX Universal Transmitter Quick Start Guide 53 8.1.3 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:
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. 8.1.4 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 2mA) 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:
XNX Universal Transmitter Quick Start Guide 54
Note:
Zero gas and Span gas should be at roughly the same humidity levels to avoid erroneous cell responses.Note
The Gas Calibration menu is for both Zero and Span Calibration.Warning
As some test gases may be hazardous, the Flow Housing outlet should exhaust to a safe area.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.
XNX Universal Transmitter Quick Start Guide 55 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.
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
Mibk
3* Xylene 2*
XNX Universal Transmitter Quick Start Guide 56 To cross calibrate the MPD-CB1 combustible gas sensor:
Note
These settings must only be used with a calibration gas concentration of 50% LEL.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%.
XNX Universal Transmitter Quick Start Guide 57
Example
If target gas to be detected is Butane and the calibration gas available is Methane (50% LEL):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. 8.1.7 Calibrating the 705/705HT For more complete calibration and configuration information, see the Type 705 Operating Instructions (p/n:00705M5002). 8.1.8 Calibrating the Sensepoint/Sensepoint HT For more complete calibration and configuration information, see the Sieger Sensepoint Technical Handbook (p/n:2106M0502). 8.1.9 Calibrating the Searchline Excel and Searchpoint Optima Plus Complete calibration and configuration information can be found in the Searchline Excel Technical Handbook (2104M0506) and the Searchpoint Optima Plus Operating Instructions (2108M0905). If properly installed and maintained, the Searchpoint Optima Plus sensor will not require routine calibration. This is due to the inherent stability of the IR absorption process and the unit’s fully compensated optical configuration.
XNX Universal Transmitter Quick Start Guide 58 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 qualified personnel. Take appropriate precautions with cylinders of flammable 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.
