XNX Universal Transmitter Warning: When the transmitter is equipped with the optional Remote Mount Kit, the remote sensor must be securely mounted in a fixed position. The Remote Sensor kit is not intended to be used as a hand-held sensor. Integral Mounting Lugs The transmitter is configured with five cable/conduit ports built into the housing for wiring and mounting sensors. Figure 25 provides the guidelines to proper installation of the XNX.
XNX Universal Transmitter 2.2 Wiring the XNX Transmitter Caution: Before wiring the transmitter, confirm that the correct personality and communication boards are installed. The XNX transmitter is available in sensor technologies, or personality options, which support a variety of sensors and applications. Each of the personalities use dedicated interface boards. Pluggable terminal blocks are used for easy connection and service.
XNX Universal Transmitter Single Transmitter 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 depending on the limitations of the device for the generic 4-20mA input. This is the simplest type of installation. It consists of a single XNX transmitter installation per power source. Loads The use of high inrush or inductive loads may affect the performance of the transmitter. For best reliability use resistive loads only.
XNX Universal Transmitter • Fewer power sources. important. Power supplies are rated by voltage and power. The nominal voltage for all XNX transmitters is 24V with the power required depending on the number of points using the same power supply. Disadvantages: • Larger power source will be needed • If a power source fails, several monitoring points fail.
XNX Universal Transmitter Searchpoint Optima Plus (10 watts). A 25 watt power supply would probably handle this installation, but a 30 watt power supply would be a better choice. Single Transmitter Distances 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. Thinner wire (i.e., 18 AWG) will lose more voltage than thicker wire (i.e., 12 AWG).
XNX Universal Transmitter Daisy-Chained Transmitter Distances 3 Transmitters - Distance “d” It is difficult to calculate distances for this configuration. There are many factors to be considered: distance from control room to first transmitter, distance between transmitters, sensor types, etc. A few scenarios are presented here to provide a base to work from.

XNX Universal Transmitter 3 Calibration XNX Universal Transmitter Technical Manual 89
XNX Universal Transmitter 3.1 3.2 Calibration Gas Calibration Menu Each of the sensor technologies supported by the XNX® Universal Transmitter uses unique calibration procedures. The description provided illustrates the XNX interface with the sensor. The description does not replace the procedures found in each sensor’s operating manual. Warning: Do not use the XNX Universal Transmitter in oxygen-enriched atmospheres. Concentrations displayed will be adversely affected by oxygen depletion.
XNX Universal Transmitter 3.2.1 Zero and Span Calibration for XNX EC Sensors, mV Sensors, and Searchpoint Optima 3.2.2 Calibration Procedure This section outlines the steps for calibrating the transmitter’s attached sensors. Caution: Before initial calibration, allow the sensor to stabilize for 30 minutes after applying power. When in Zero and Span Calibration modes, the current output from the sensor is inhibited (default 2mA) to avoid false alarms.
XNX Universal Transmitter As the sensor detects the gas and the concentration increases, the values displayed will reflect the changing concentration. When the concentration values are stable, 3 minutes, select ✓ to allow the transmitter to calculate the zero adjustment. Selecting ✖ will return to the Gas Calibration menu. Figure 198. Span Gas Concentration Screen 5. Enter the concentration of the span gas by selecting ✓ to choose the first digit. Use the switches to increment or decrement the values.
XNX Universal Transmitter 3.2.3 Using the Calibration Cup Refer to Figure 203 to attach the calibration cup: 1. Snap the calibration cup into the weather protector. The two protrusions on the cup fit into recesses in the weather protector. Figure 200. Span Passed Screen 2. Attach the hose from the gas cylinder to the calibration cup. Note that the cup’s flow is unidirectional.
XNX Universal Transmitter 3.2.4 Zero and Span Calibration of XNX EC Hydrogen Sulfide (H2S) Sensors Caution: Before initial calibration, allow the sensor to stabilize for 30 minutes after applying power. When in zero and span calibration modes, the current output from the sensor is inhibited (default 2mA) to avoid false alarms. Warning: Long-term exposure (> 20 minutes) to concentrations exceediing the full-scale range of the sensor can cause it to lose sensitivity.
XNX Universal Transmitter 4. Begin the span calibration by entering the concentration value of the calibration gas: Select ✓ ✓ to choose the first digit. Use +/- to increment/decrement values. Select ✓ ✓ to accept the value and move to the next digit. Use calibration cover P/N 2108B0272 to perform span calibration at a flow regulator of 1 LPM. (If a span calibration is not required, select ✖ to return to the calibration menu.) z Figure 205. Gas Calibration menu 2. Perform a zero calibration.

If the calibration is not successful, the Span Failed screen will be displayed.
XNX Universal Transmitter 3.2.8 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. Figure 214. Flow Housing 3. Reverse the cap removal procedure. Figure 215 shows the flow housing accessory fitted to the MPD. Caution: Before initial calibration allow the sensor to stabilize for 30 minutes after applying power.
XNX Universal Transmitter 3.2.10 XNX EC Sensor Operational Life Sensors should be calibrated at concentrations representative of those to be measured. It is always recommended that the sensor be calibrated with the target gas it is to detect. The typical life of a toxic gas sensor dependst on the application, frequency, and amount of gas exposure.
XNX Universal Transmitter 3.3 Functional Gas Testing (Bump Testing) 2. If the difference between the reading and the applied gas concentration is outside the acceptable limits for the application, follow the procedures for zeroing and calibrating the sensor (see Section 3.2.1). 3. If the reading is still inaccurate, replace the sensor (see Section 4.1). Figure 216.
XNX Universal Transmitter 3.4 Calibrate mA Output Note: Calibrated mA output is required for proper operation of internal diagnostics. Use Calibrate mA Output to adjust the milliamp output to provide the correct output levels at peripheral devices connected to the transmitter. An F165 fault will be reported if the 4-20 mA calibration fails. 3.5 Align Excel (Searchline Excel) Figure 219.

XNX Universal Transmitter 4 Maintenance XNX Universal Transmitter Technical Manual 103
XNX Universal Transmitter Warning: When servicing or replacing sensors, reduce the risk of ignition of hazardous atmosphere by declassifying the area or disconnecting the equipment from the supply circuit before opening the sensor enclosure. Keep the assembly tightly closed during operation. 4.1 MPD Sensor Cartridge Replacement Using Figure 226 as a guide, follow this procedure: 1. Verify that the label on the new sensor is the correct gas type. 2. Remove power from the transmitter. 3.
XNX Universal Transmitter 4.2 XNX® EC Sensor Cartridge Replacement Caution: For toxic sensors, remove the shorting clip from the bottom of the sensor prior to installation. No shorting clip is provided with oxygen sensors. The serviceable sensor allows replacement of the cell inside the sensor. The sensor cell can be replaced with a cell of the same type or changed to detect a different target gas. Both procedures follow. Figure 227. Sensor screens during warmup 9.
XNX Universal Transmitter 4.2.2 Replacing with a Different Cartridge Type and the original cell is no longer recognized. This fault condition will clear after the transmitter has been properly reconfigured. To replace the cell with a cell for a different gas, follow this procedure: 1. Unscrew the weatherproof cover, loosen the sensor retainer locking screw, and unscrew the sensor retainer. 2. Remove the old sensor by pulling without twisting. 3. Unscrew the sensor cap. 4.

XNX Universal Transmitter A.1.2 DevComm PC-based HART Interface Overview The XNX-HART interface facilitates remote access to all features of the local user interface including displaying status, testing, calibrating, and configuring. A device descriptor (DD) file is available to adapt standard tools for use with the transmitter. Warning: After changing parameters with a handheld device, verify that the parameter settings are correct at the transmitter.
XNX Universal Transmitter Functions in the Configure Menu and the security levels required to change them are explained in this table.
XNX Universal Transmitter Information Screens All of the information in the Configuration Summary can be viewed live on various informational displays. For example, alarm settings are shown in Figure 242. Figure 243. HART Event History Display Test The test menu provides methods for inhibiting the output, exercising the analog output, or simulating alarms or faults. These methods simplify common tasks by providing a simple user interface. Figure 242.
XNX Universal Transmitter Calibration The calibration menu permits calibrating zero or span and bump testing. Additionally, when fitted with a Searchline EXCEL sensor, the Calibrate menu displays the optical signal strength for mechanical alignment. The gas calibrate operation is shown below. Figure 246.
