GENERAL DESCRIPTION

The Trolex AIR XD particulate monitor is designed to provide detailed, accurate, real-time data on airborne particulates so that users can take appropriate actions to stay safe and ensure personnel are fully protected from particulate-related health hazards. The AIR XD allows users to simultaneously monitor multiple Particulate Matter (PM) sizes (PM1.0, PM2.5, PM4.25, PM10, as well as custom sizes) and can report on Total Suspended Particulates (TSP). Precise data is collected for measurable particulates, enabling detailed size profiling and analysis using the application software.
The AIR XD uses an innovative optical particle counter (OPC) that combines adaptive particle flowrate with advanced sensing technology to ensure a high level of measurement accuracy.
The size of each particle is instantaneously measured and classified at up to 10,000 samples per second to allow detailed real-time reporting in high dust environments.
As the AIR XD records data on all particulates between 0.35 μm and 40 μ m, users can easily access and view detailed information about a wide range of PM sizes. Measurement information can be viewed via the instrument display or as live or historical readings using the application software.

supply

5.1 TX8005 AIR XD Dust Monitor
The AIR XD Dust Monitor uses an OPC that is located inside a robust stainless steel housing. This provides isolation and ingress protection between the particle flow path and the main control circuits. Control circuits are housed in a lockable, IP66-rated coated steel enclosure. Information and settings can be accessed using the keypad and display located on the front of the instrument.
The AIR XD can be configured to report on PM size concentrations or TSP based on user requirement, with the option of two configurable setpoint relay outputs. Detailed information can be transmitted via an RS485 or ethernet connection to a computer running the Trolex Breathe software or downloaded directly from the internal memory module using a USB storage device.
The figure below shows the location of the navigation buttons, display screen and status LEDs. Power and network connections enter the main housing via cable entry glands located on the bottom of the instrument. The AIR XD can be wall or stand mounted via mounting brackets.

5.2 Particle flow path
The AIR XD has been designed with the ability to restrict ingress through the particulate flow path during routine maintenance and cleaning periods. A rotational top cap is used to ‘open’ or ‘close’ the particle flow path to provide increased ingress protection during cleaning. It is recommended that the top cap is set to the ‘closed’ position during instrument maintenance and cleaning to ensure the dust sensor is not exposed to unnecessary ingress. When the top cap is rotated into the ‘closed’ position, the AIR XD conforms to IPX6. The AIR XD can detect whether the flow path is ‘open’ or ‘closed’ and will record top cap positions to aid with instrument maintenance schedules. Note: Rotate the top cap to move between ‘open’ and ‘closed’ positions.

11.45 Data download
The AIR XD allows users to download collected data sets via the “Data Download” menu. Data is stored on the instrument internal memory and can be locally downloaded onto a removable USB device when connected via the external USB connector positioned at the base of the instrument.
Note: It is recommended that a USB with at least 8 GB of storage capacity is used for local data download. The AIR XD only supports FAT32 file formatted USB devices. Trolex recommends the use of a dedicated USB device formatting tool, such as AOMEI Partition Assistant or similar when converting large storage sizes to FAT32 file format.

  • Collected data can be retrieved from the AIR XD instrument by either selecting the “Download All” or “Download New” data sets.
  • Selecting the “Download All” tab will notify users of the number and total size of the files to be downloaded.
  • Selecting the “Download New” tab will notify users of the number and total size of the files to be downloaded.*

*This function works based on reading the last file name downloaded to the connected USB device and only downloading the data set recorded after the last download.

11.46 Memory module
The AIR XD contains an internal memory module that is used to locally store collected data sets on the instrument. The module can be configured from the settings menu to allow local data collection to take place or to stop the AIR XD from writing to the internal memory.
For the majority of applications, the internal memory module will be used and configured to allow the AIR XD instrument to locally store data as well as push data to the Air X software via selected communications channels.
For applications that may require power saving functionality, the internal memory module can be de -selected.
Note: The current selection is highlighted by the ‘selection tick’.

Trolex TX8005 AIR XD Dust Monitor - menu4

The internal memory module contains 8 GB of storage capacity, which, depending on the frequency of data collected and written, may require clearing. To clear the data set stored on the instrument, follow the on-screen functions detailed below.

Trolex TX8005 AIR XD Dust Monitor - menu5

11.47 Firmware update
On notification of a firmware update and release, the AIR XD and internal memory module can be updated via the firmware update menu below. The instrument requires the update to take place via the connection of an external USB device loaded with the latest firmware. See section 13 for full details on how to update for full details on how to update the firmware of the device.

Trolex TX8005 AIR XD Dust Monitor - menu6

11.48 Relay override
If the alarms are enabled, in normal operation the relays will switch over if the assigned alarm threshold is exceeded. In some applications it may be necessary to override the relays to switch on a piece of equipment manually even if the alarm threshold has not been exceeded. To allow this functionality, coil registers (13 and 14) are provided for overriding the relays.
To move a relay to the normally open position, write ‘1’ to the corresponding relay. To place the relays back under the control of the alarms by writing ‘O’ to the relay.
The relays can also be overridden even when the alarms are disabled.
11.49 Watchdog
The AIR XD contains an electronic watchdog to detect and recover from malfunctions without requiring input from the user. Once a device anomaly or malfunction has been detected, the unit will automatically implement a restart sequence.
The instrument will take up to 10 seconds to initiate a soft reset. On recovery from a soft reset, the time based averages are restored and the instrument will continue to log data from the point recorded before the watchdog reset.
Note: In the event of a hard reset, time based averages are reset to factor default (removal of power, then re-application).

12.4 Reading floating point registers
MODBUS itself does not define a floating point data type but it is industry standard to use the IEEE-754 standard for defining floating point numbers. There is, however, there is no clear-cut definition of the byte order of the data payload.
By default, the Trolex AIR XD XD uses a little-endian format for the floating point numbers split across two 16-bit MODBUS registers. If this is not compatible with your system and a big endian format or byte swapping is required, the byte ordering can be switched using the on-device menus as shown below.

Trolex TX8005 AIR XD Dust Monitor - menu7

The order of the byte forming the floating-point registers can also be configured remotely through writing to the coil registers.
Coil registers 16 and 17 enact this functionality with the logic table outlined below.

Coil register 16| Coil register 17| Floating point register
---|---|---
0| 0| Big endian
0| 1| Big endian byte swap
1| 0| Little endian
1| 1| Little endian byte swap

Function code “1” read.
Function code “5” write.
This is a read/write register containing the instrument binary settings, including alarm status, PM units and 4 – 20 mA output “Enable”/“Disable” status.
Writing to this register will result in the setting being changed permanently. However, if an alarm is activated, writing to the alarm status coil will dismiss the active alarm until the alarm threshold parameters have been re- exceeded.

12.6 Holding register
Function code “3” read.
Function code “6” write.
This is a read/write register containing the instrument settings and parameters, including instrument date, time, PM assignment and MODBUS settings. Writing to this register will result in the setting being changed permanently.
Note: Writing to the MODBUS settings will result in communication errors until the user has changed their local instrument MODBUS parameters to match the new setting selected on the AIR XD.

12.7 Instrument self-test
On initial power on, the AIR XD is programmed to perform a set of initialisation tests, which are listed and described below. Throughout general function, the AIR XD will periodically perform these tests to ensure correct operation.

  • OPC sensor communications check
    Ensures commiunications and correct functionality of the OPC sensor.

  • OPC temperature sensor test
    Ensures the OPC sensor is operating within the specified safe temperature limits.

  • 4 – 20 mA self-test
    During instrument start up and initialisiation, each 4 – 20 mA output will perform a calibration routine which involves sweeping the output from 0 – 20 mA before returning to 4 mA. After this has been completed, the output will return to configured functionality.

  • Data logging comms test
    Ensures communications and correct functionality of the AIR XD memory module.

  • EEPROM memory test
    Ensures communications and functionality of the EEPROM is correct and that custom defined user settings are not lost.

UPDATING FIRMWARE

To perform a firmware update, the instrument requires a connection to an external USB drive, formatted to the FAT32 file system, which has been loaded with the latest firmware release.
Connection to the USB drive is made via the USB interface port located on the underside side of the AIR XD as shown in the figure below (remove the IP-rated cover cap to access the USB interface).
Firmware updates should only take place on notification and release from Trolex or an approved distribution partner.

Trolex TX8005 AIR XD Dust Monitor - UPDATING FIRMWARE

13.1 Units with controller v1.2.3 or earlier and/or memory module v1.4 or earlier
Updating the firmware will result in loss of data download. Ensure that all data is downloaded from the unit before an update is undertaken.
After the memory module has been updated, data logging will only commence after the memory module has been cleared using the on-device menus, the steps for which are outlined in section 11.46.
13.2 Preparation
The following steps should be taken prior to updating the instrument:

  1. Format a memory stick to FAT32 file system.
  2. Copy the firmware files provided by Trolex or an approved distributor onto the formatted memory stick. The controller files have the format “P5628.704_xx_cont.hex” and the memory module files have the format “P5628.705_xx_mm.hex” (where “xx” is the firmware revision).
  3. Insert the USB drive into the AIR XD USB interface connector, the display background will turn green on successful paring with the device.

13.3 Steps to update the controller

  1. Navigate to the firmware update menu as shown below and then select the “Controller” on the select device menu.
    Trolex TX8005 AIR XD Dust Monitor - Confirm update

  2. Press “YES” to confirm the update, and the controller will then clear the memory in anticipation for the update and a screen will display “Receiving Packet x of x”. Once this is underway, it can take up to 30 minutes to receive all data packets.

  3. Once all packets have been received, the unit will restart and perform the update. During this time the screen will go blank for up to 60 seconds. Do not remove power during this time.

  4. When the update is complete, the unit will reboot, and the new version number will be displayed on the start-up screen and in the “System info” screen.

13.4 Steps to update the memory module

  1.  Navigate to the firmware update menu as per controller update. Selecting the Memory Module on the select device screen.
  2.  Press “YES” to confirm the update, the memory module will then begin receiving data from the USB device. The display will show a message reading “Receiving Data…”
  3. The firmware update should take no longer than 60 seconds. If the update is a success, a confirmation screen is shown and the user is presented with a “Confirm unit restart” message.
  4. Press “Confirm” on unit restart and the instrument will reboot. To view the new memory module firmware version, navigate to the system info screen as shown below.
    Trolex TX8005 AIR XD Dust Monitor - Confirm update1

Note: When updating the memory module firmware, all saved data log files will be lost and overwritten. Please ensure all data has been locally downloaded from the unit before proceeding.
After the firmware update, ensure that the ‘Wipe data’ function has been performed before resuming normal operation.

MAINTENANCE

The maintenance of the AIR XD must only be carried out by competent personnel.
Maintenance should be considered with reference to the local safety regulations, authorities, and guidelines.

14.1 Visual checks
Periodic visual checks should be carried out to assess if there are any issues arising with the AIR XD instrument. Check for:

  1. External damage to the instrument. Plastic parts should not be cracked or broken, which could affect the IP rating of the instrument.
  2.  Internal or external damage to wiring that is connected to the AIR XD instrument.
  3. Labels on the instrument are still in place and are not peeling or discolouring.

14.2 Cleaning labels
It is recommended to periodically clean the instrument with a damp cloth, to ensure the display, keypad and rating labels are clean and legible.
14.3 Air entry/exit apertures
The AIR XD has been designed to allow for infrequent pressure washing during maintenance schedules.
Note: Ensure inlet cap is closed before pressure washing the AIR XD instrument.
It is important that an appropriate distance is kept between a pressure washer and all AIR XD surfaces when cleaning to avoid any damage to the surface being cleaned. Care should also be taken to ensure that the underside of the instrument is not subject to the direct water jet to ensure that water does not enter the air flow path.
The air exit aperture is protected by a stainless steel grille to minimise the ingress of debris into the instrument. It is recommended that the grille is checked and cleaned during maintenance periods.
14.4 Filter replacement
It is recommended that the AIR XD is installed with location and proximity consideration to atomising dust suppression systems.
Instrument readings will include atomised or misted sizes that pass through the AIR XD sensorwithin the particle detection range.
14.5 Preventative maintenance

---|---|---
Low| Up to 5 mg/m| 6 to 12 months
Medium| Up to 10 mg/m| 3 to 6 months
High| 10 mg/m or above| 1 to 3 months

Particulate types and operating environments vary, therefore the maintenance schedules above should be used as a guide only.
An assessment of site environmental and operating conditions should be carried out periodically to assess the required maintenance.
14.6 Sensor cleaning
As part of the routine maintenance schedule, it is recommended that the sensor is cleaned from time to time following the steps below.

  1. Wipe down the AIR XD inlet surfaces with a damp cloth in both ‘open’ and ‘closed’ positions.
  2.  Using canned compressed clean air, spray the device inlet for 10 to 15 seconds to clean the dust path.

14.7 Compliance audit check
The AIR XD has been designed with an inbuilt compliance audit routine/test to allow for the infrequent checking of device functionality against a selection of sized reference particulates.
The on-device compliance audit routine must be carried out using the Trolex Compliance Audit Kit, which contains the accessories required to conduct the procedure, including:

  • Particle dispersion hood
  • Reference particle sizes (reference material)
  • Dosing bottle
  • Carry case

The following on-device compliance audit check menu sequence will be presented.

check

  1. “Navigate to the “Settings” > “Maintenance” > “Compliance Test” on the AIR XD device.

  2. Follow the on-device instructions and select the reference material size required from the “Choose PM Size” menu.

  3. The AIR XD will reset the memory module in preparation to perform the test. An on-device message will be displayed “Resetting Memory Module – Please Wait…”

  4. Following the reset, the AIR XD will prompt a clean down. It is important to ensure that the AIR XD particulate inlet has been cleaned following the steps outlined in section 14.5 before selecting “Yes” and proceeding with the test.

  5.  Ensure that the AIR XD top cap is open and select “Yes” to proceed.

  6.  Once it is confirmed that the top cap is open, the AIR XD will prompt the fitting of the  articulate dispersion hood that is supplied with the Trolex Compliance Audit Kit. It is important to ensure that the particulate dispersion hood is fitted to the AIR XD as shown below and thatthe dosing opening is accessible.

  7. Before selecting “Yes” to continue, ensure that the particulate dosing bottle is filled with the required reference material and ready to be presented to the AIR XD.

  8. “After selecting “Yes” from the “Fit Particulate Hood” screen, use the particulate dosing bottle containing the required size reference material to dose the particulate dispersion hood for the first 10 seconds of the compliance audit check.
    Note: It is important to dose the AIR XD unit with several measures of the reference particulate material during the first 10 seconds of the compliance audit check.

  9. The AIR XD will continue to count down and analyse the sample particulate dose for the remain test time frame.

  10. On sampling completion, the AIR XD will return an on-screen “Pass” or “Fail” result based on the test results and sampled reference particulate. Please see section 14.7 for detailed test information.

  11. On return of a test result, and completion of the compliance audit test, the AIR XD will restart the memory module and revert to sampling function/data logging mode.

Note: Users may be required to clean the particle dispersion hood between compliance audit tests.
14.8 Compliance audit check – results
The AIR XD is designed to return an on-device “Pass”/“Fail” result based on the compliance audit check results and operational threshold for the applicable particulate sizes.
Return of a “Pass” result
On return of a “Pass” result, the particulate sensor is functioning as expected and normal monitoring operations can resume.
Return of a “Fail” result
Run a sensor cleaning operation as highlighted in section 14.5.

  1.  Repeat the compliance audit check sequence and note the test result.
  2.  On return of a “Pass” result, the particulate sensor is functioning as expected and normal monitoring operations can can resume.
  3. On return of a repeat “Fail” result, please contact Trolex to discuss support or servicing options of the AIR XD unit.

Device logged test data
As the AIR XD test procedure is completed for each particle size, the unit automatically exports specific ‘TRX’ files for the logged test period only. These are saved with a specific file name prefix (‘QA’) to identify them from normal operational data logging file sets, which can be imported into Trolex Breathe software and analysed as required.

TROUBLESHOOTING

The following sections detail and contain information to assist with the troubleshooting of instrument functionality if required. If an issue is non- resolvable based on the information below, please contact the Trolex product support team.
15.1 High temperature operating
The AIR XD operates a protective thermal cut-out sequence when the temperature inside the instrument exceeds the maximum operating temperature specification detailed in section 7. This protective measure is in place to maintain the lifespan and operating functionality of the optical sensor assembly when the AIR XD is installed in environments with high ambient temperatures.
15.2 Low temperature start-up
If the internal temperature of the instrument is suspected to be below -10°C, for example, if it has been left powered off for a period of time in a very cold environment, damage to the optical assembly may occur when power is applied. Allow the instrument to reach safe operating temperature before applying power.
15.3 Fault codes
The following codes relate to on-screen warnings that the AIR XD will display when a fault is encountered during normal operations.

Code Fault name Fault description Fault check
0x0009 Failed to load settings Failed to load and apply user-configured
settings. As standard, the AIR XD default settings will be applied. Re-apply

custom settings and check if unit saves and restores files. Contact Trolex or an approved distributor if this fails.
