Product Information
The Trolex RockMonitor XR is an intrinsically safe system primarily designed to monitor the condition of roof-bolted underground roadway strata. It offers a fully networked solution for measuring displacement of tunnel strata, allowing geotechnical engineers and mine operators to continually monitor and assess critical information regarding the safety and effectiveness of roadway support structures.
A typical RockMonitor XR system consists of multiple telltale devices connected to a fixed controller. Power is provided to the controller via a suitable intrinsically safe power supply with the controller communicating to application software installed on a surface PC via an appropriate communications barrier. A portable reader is also available for system diagnostics.
The system is designed to be progressively configurable in an advancing roadway drivage. Telltales can be added and removed from the network seamlessly with the controller dynamically reconfiguring the telltale network as the number and position of devices changes.
Product Usage Instructions
- Ensure that the RockMonitor XR system is connected to a suitable intrinsically safe power supply.
- Connect the fixed controller to a surface PC running the Trolex|Core software using an appropriate communications barrier.
- If necessary, use a portable reader for system diagnostics.
- To monitor the condition of roof-bolted underground roadway strata, install the telltale devices at multiple anchor points.
- For optimal insight, place one telltale device above the bolted height and one within the bolted height.
- For even more data, consider using a four-anchor setup to optimize bolting strategies.
- Monitor the displacement of strata by observing the movement of displacement markers on the telltale devices.
- Interpret the displacement figures represented by the movement of the displacement markers.
- To add or remove telltale devices from the network, ensure that the system is in an advancing roadway drivage and let the controller dynamically reconfigure the telltale network accordingly.

General Description
The Trolex RockMonitor XR is an intrinsically safe system primarily designed
to monitor the condition of roof-bolted underground roadway strata. It offers
a fully networked solution for measuring displacement of tunnel strata,
allowing geotechnical engineers and mine operators to continually monitor and
assess critical information regarding the safety and effectiveness of roadway
support structures.
Electronic extensometers (hereafter referred to as telltales) give local
visual indication combined with electronic displacement measurement to provide
continuous information regarding strata condition. Spring anchors are used to
locate a set of wires at different heights inside a borehole. The wires are
connected to both the visual indicator and electronic measurement mechanism.
Any dilation or bed separation of the strata will appear to pull the
indicators along their axis showing how much each anchor has moved (relative
to roadway roof) with the electronic measurement data being sent back to a
controller that then communicates with application software running on a
surface PC or server. Regular data analysis allows monitoring of strata
condition/dilation and hence the safety and effectiveness of the roof-bolting
arrangement.
A typical RockMonitor XR system consists of multiple telltale devices
connected to a fixed controller. Power is provided to the controller via a
suitable intrinsically safe power supply with the controller communicating to
application software installed on a surface PC via an appropriate
communications barrier. A portable reader is also available for system
diagnostics.
Telltales can be installed at varying intervals in the sides as well as the
roof of a tunnel and are designed to be plug and play with new instruments
automatically configuring themselves once connected to the controller. Up to
150 telltales can be connected via 3-core wire in a daisy chain or spur
configuration allowing for flexible system layouts over distances up to 6km.
Once configured the controller then begins polling the telltales in sequence
to obtain readings, pushing the data via RS485 or Ethernet to application
software installed on a surface PC. The application software can easily export
data to site SCADA systems to facilitate continuous monitoring of the strata
condition.
The system is designed to be progressively configurable in an advancing
roadway drivage. Telltales can be added and removed from the network
seamlessly with the controller dynamically reconfiguring the telltale network
as the number and position of devices changes.

Main features
Continuous monitoring of strata displacement · Strata displacement measurement up to 150mm (without reset) · Resettable height measurement for movement in excess of 150mm · Two or four monitoring points (anchor heights) between 0.6m and 16m · Monitor tunnels over distances of up to 6km with a single system · Connect up to 150 telltale devices per controller · Flexible topology, configurable as either spur or daisy chain · Fully customizable alarm settings including rate of movement and absolute displacement · Automated notifications via software or e-mail · Highly visible display of displacement on-device · Plug and play Installation · Detailed monitoring and display of data using powerful application software · Integration with SCADA systems
Theory of operation
The RockMonitor XR Telltales can be configured with either two or four
measurement channels. Anchor wires are inserted into a borehole drilled either
in the roof or side wall of a roadway and secured into position using spring
anchors connected to the ends of the wires. The tube section of the telltale
is then inserted into the borehole with securing features automatically
gripping the sides of the borehole and keeping the telltale in position in the
tunnel roof or side wall. Any displacement of the strata occurring within the
height of the anchors will cause the body of the RockMonitor XR Telltale to
move relative to the anchor. The anchor wires connect the anchor points to
electro-mechanical measurement units housed within the body of the telltale.
Movements are then shown visually on-device whilst also being communicated
back to the network controller which transmits the data back to a surface
computer.
The use of multiple anchor points allows more detailed insight into where the
strata displacement is occurring. A typical installation would use a minimum
of two anchors, placing one above the bolted height and one within the bolted
height. This can provide valuable insight into the effectiveness of the chosen
support strategy. The four-anchor version provides even more data with which
to optimise bolting strategies.

2.1 RockMonitor XR Telltale TX5001
The electro-mechanical measurement system is housed within a robust stainless- steel enclosure that remains visible after installation in the tunnel roof. Anchor springs fix the anchor wires into the borehole whilst the vertical tube is secured into the borehole by the three borehole grippers, allowing the stainless-steel body of the device to maintain a low profile to the roof or side wall. As displacement occurs, the anchor wires pull a metal tube through a coil of wire causing the inductance to change. The change in inductance is measured and converted into a value for displacement which is then communicated back to the controller. The anchor wires are secured to the measurement mechanism using clamping devices with a spring providing tension on the wires to ensure accurate measurement.
The figure below shows an individual telltale with four anchors (note that the full lengths of the anchor wires are not shown).

Power/data cable Daisy chain or spur
Measurement indicators give easily visible local information regarding displacement of each individual anchor. A 3-core cable provides power to the device and allows communication with the RockMonitor XR Controller.
The telltales operate in low power receive mode to limit the power consumption of the network. The controller polls each telltale individually, cycling through the entire networking until all readings have been taken. Once the telltale receives its wake command it wakes up and sends the displacement data to the controller. It takes between 5 and 10 minutes to cycle through a network of 150 devices.

5 Hardware Installation
The RockMonitor XR has been designed to be as simple to install and commission
as possible. Nevertheless, installation in underground environments can be
challenging and correct set up is critical to the function of the system.
RockMonitor XR Telltales are plug and play such that they can be installed as
a network in advance of connection to a RockMonitor XR Controller or they can
be dynamically added to an existing network without the need to remove power
from the controller. Once connected to the network and power applied, the
controller automatically configures the network. Telltales added to an
existing system will be automatically set up without the need to reconfigure
the entire system. Once configured, the controller will start polling
immediately, communicating with each telltale device to start recording
displacement measurements.
To set up the RockMonitor XR Controller the user must provide power and a
connection to the communications network. Aside from selecting the appropriate
IP/COM port little or no user interaction is required to configure the network
and have the controller send data back to the surface PC
Installation can be considered in two parts:
1. Installation of the RockMonitor XR Telltales and wired connection to the
controller 2. Installation of the RockMonitor XR Controller and its
communications link to the surface PC
The system must be installed as detailed in Section 3. In addition, the
installation work must comply with the conditions of safe use as detailed in
section 3.1.2 and 3.1.3 as well as the appropriate national installation
requirements.
Peripheral components such as the power supply and communications barrier must
be installed according to the manufacturer’s instructions and the mine’s
prevailing statutory regulations.
The installation of the product must only be carried out by competent
personnel. Each installation needs to be considered with reference to the
local safety regulations and authorities. Refer to the following standards for
additional guidance:
· IEC/EN 60079-14 · IEC/EN 60079-25 · EN 50628:2016
Refer to the Certification Section of this User Manual and to the relevant
certificates for any installation parameters and special conditions of safe
use.

RockMonitor XR System User Manual 5.1 Telltale Installation
To install a RockMonitor XR Telltale into a tunnel roof or sidewall, follow
the procedure below: 1. Drill a 35mm-45mm bore hole to the height required for
the top most anchor.
2. Cut a hole in the roof mesh large enough to ensure there is no
interference to the telltale body once installed.
3. Using the integrated installation hook located in the top anchor, hang the
device off the roof mesh as close to the bore hole opening as possible. Ensure
the yellow installation hold-off tab is left in place.
4. Remove the wire reel for anchor 1 and allow to unspool.
www.trolex.com
P5625.1600 Rev E 24
5. Using an installation rod push anchor 1 up the bore hole to the required
height. Repeat these steps for heights 2, 3 and 4.
6. Pull down on each wire placed into the bore hole to ensure the spring
anchors find a lie within the hole.
25 P5625.1600 Rev E

RockMonitor XR System User Manual
7. Unhook the device from the mesh and push the device as far as it will go
into the bore hole taking care to push from the centre of the device body.
8. Pull the slack cable through the device from the back end as you do this.
9. Device orientation will be dependent on local strata conditions and should
be determined on a case by case basis. However, use of the side scale for
viewing at distance requires the telltale to be mounted perpendicular to the
direction of travel.
10. Remove the handle installation hold-off tab (the yellow plastic strip).
www.trolex.com
P5625.1600 Rev E 26
11. Ensure all marker handles sit flush against the device and are not stuck in the down position.
12. Pull on each cable coming out of the device to remove slack in the line.
13. Excess cable can be removed with wire cutters. However, care must be
taken to ensure there is enough cable to allow for potential resetting of
anchors.
14. It is recommended that a suitable amount of cable remains after cutting
to allow for any number of anchor height resets. Each reset requires 150mm of
cable, plus 100m of remaining cable to allow for tensioning and to prevent the
end of the cable being lost inside the device. Please calculate the cable trim
length based on your system requirements.
15. Connect the blue power/data cable to the rest of the network in the
required manner.
Note: the RockMonitor XR Telltale has two configuration options; daisy-chain
or spur. In a daisychain configuration it is possible to connect the blue
power/data cables directly between telltales, connecting the output from one
to the input of the next using crimps or a junction box. In a spur
configuration, the power/data cables are typically connected to the main trunk
line via a junction box.

Telltale Orientation
It is important to consider the appropriate installation orientation of
individual Telltales when fitting or expanding a RockMonitor XR system.
Telltale devices have been designed to allow for various installation options
when mounting into a mine roof or sidewall whilst offering the maximum
protection from unnecessary ingress. Please follow the orientation
installation guide below.
5.1.1 Roof Mounting A device can be mounted directly into the mine roof with
the Telltale body being positioned in any degree of angle about the bore hole
centre. It is recommended to orientate the device so that it is perpendicular
with the walls of the roadway. This will allow for the side scales on the
device and the anchor indicators to be viewable down the roadway from both
sides.
Roof Mounting Orientation
5.1.2 Sidewall Mounting
A device can be mounted directly into a mine sidewall with the Telltale body
being positioned in a fixed orientation about a 180-degree angle around the
bore hole centre. It is recommended to orientate the device so that the scale
label is on or below a horizontal installation position to ensure suitable in-
situ ingress draining takes place.
Sidewall Mounting Orientation
www.trolex.com
P5625.1600 Rev E 28
During sidewall mounting, the device should never be installed with the scale
label positioned above the horizontal installation level.

Controller Installation
The location of the RockMonitor XR Controller is the prerogative of the mine.
The system has been designed to support operation over long distances thus
giving as much flexibility as possible for where to locate the controller. It
is possible to position the controller several kilometres from the first
telltale in the network. Typically, consideration will be given to the
location of a suitable power supply, access to the communication network and
the protection of cabling from damage.
1. Secure the controller to a suitable mounting surface using the mounting
brackets provided. 2. Unlock and open the enclosure door to access the
internals of the controller. 3. Run the required cables through the cable
glands provided in the bottom of the enclosure. 4. Wire the cables into the
relevant terminals on the internal plate. 5. Tighten the cable gland against
the cable to ensure an IP seal. 6. Close and lock the door after use to
maintain IP rating of the enclosure.
Note 1: Only on controller shall be used to power a single telltale network
Note 2: When the door is open the unit is susceptible to ingress so care must
be taken to ensure the location is clean during installation.
5.2.1 Connections The figure below shows the connections available internally
in the controller. The connections can be accessed by opening the front
housing of the controller using the supplied key. The connections are clearly
labelled on the internal metal plate. Wires are inserted into the connector
terminals by first using a small flat head screwdriver inserted into the small
recess above the appropriate terminal. Pushing the screwdriver down into the
mechanism opens the connector terminal allowing the wire to be inserted into
the opening. Before placing the wire into the connector, ensure that the wire
has been stripped back sufficiently to allow a good electrical connection.
Once the wire has been sufficiently pushed into the terminal, remove the
screwdriver to allow the mechanism to clamp the bare wire end. Give a gentle
tug on the wire to make sure it has been clamped sufficiently by the
connector. Details of the connections are given in Tables 1 and 2.

System Commissioning
The RockMonitor XR System is designed to be plug and play. Once the network of RockMonitor XR Telltales is connected to the RockMonitor XR Controller and power applied, the controller will automatically configure the connected devices. On connection to the communications network, the controller will start sending data to the Trolex|Core application software.
First Power On
Prior to commissioning and first use, the product should be inspected for any
visible damages and integrity of the enclosure. Never use the product that has
damaged housing in hazardous locations.
1. Ensure that the telltale network is correctly installed and connected to
the controller.
2. Apply power to the controller.
3. The loading screen will display for several seconds until the user is
presented with boot options.
4. The user will be presented with two options; Discover telltales;
Controller setup only.
Note: If it is not the first time the unit has been powered with the telltale
network connected then the controller will give the option to `Load previous
setup’. Choosing this option will load the previous network configuration. Any
new devices connected to the network will be automatically added and
configured within a few minutes.
5. Controller setup only; selecting this option will ensure that the power to
the telltale network remains off and allows the user to change controller
settings e.g. display brightness. This would typically be used when the
telltale network is not yet installed but the user would like to configure the
controller and check the communications network.
6. Discover telltales; selecting this option will trigger the controller to
search for all connected telltale devices.
7. Once discover telltales has been selected the user is presented with the
option to select the number of expected telltales on the network. This is to
allow the optimisation of the setup time, reducing the amount of time the user
must wait for the network to configure.
· 50 or less · More than 50 · More than 100
Note: if the user selects the incorrect value then the controller will still
configure the network, but it will take longer than if the correct option had
been selected.
8. The screen will then display the number of telltale devices found,
automatically incrementing every time a new device is located on the network.
This may take several minutes.
9. Once the controller has discovered all telltales the screen will display
the number of connected telltales. It will also automatically countdown the
number of telltales waiting to be configured.
www.trolex.com
P5625.1600 Rev E 32
10. Once all telltales have been configured, the telltales network is fully
initialised and will automatically start collecting data.
6.2 Network Connection
1. Once the communications network is connected and power applied to the
controller (and the appropriate serial port opened at the PC or server) the
controller will automatically connect within approximately 10 seconds and
start communicating with the Trolex|Core application software.
2. The controller will repeatedly attempt to connect, so if Trolex|Core has
not yet been installed then the controller will continue to try until the
software becomes available.
3. Once a connection to the Trolex|Core software has been established, the
controller will start transmitting data acquired from the telltale network.
6.3 Application Software
Installation and commissioning of the Trolex|Core application software is
covered in the Trolex|Core user manual.
6.4 Meter Marks
If the user would like to set the metre mark (positioning identifier
indicating distance along a roadway) for each telltale, this can be done via
the menu on the controller.
1. Hold the centre button to access the main menu 2. Select Telltale manager’ 3. SelectTelltale info’ 4. Navigate to the telltale you would like
to edit using the next and previous buttons 5. Select Config’ 6. SelectEdit
metre mark’ 7. Enter the metre mark 8. Select `Set’ 9. Repeat this for all
telltales

7 General Operation
7.1 Telltale
7.1.1 Measuring Displacement The Telltale provides local indication of
displacement by way of linear scales on the device. These are provided as
general indication only and it is recommended that the supporting Trolex|Core
application software is used to obtain accurate measurement readings. There
are two types of visual scale on the device: 1. A fine scale on the underside
of the device which provides measurement of displacement to the
millimetre. The scale should be read from the leading (front) face of the
anchor indicators.
2. A course scale on the sides of the device. These are intended to provide
general indication of displacement from a distance in increments of 10mm.
Viewing of the side scale from any angle other than perpendicular will result
in an inability to judge displacement with any accuracy.
www.trolex.com
P5625.1600 Rev E 34
7.1.2 Extending the Measurement Range The Telltale has a measurement range of
0 to 150mm, however this range can be extended if required. There is facility
to manually reset the anchor indicators back to 0 to allow for further travel
whilst maintaining the current readings. To reset the telltale, follow the
procedure below: 1. On the RockMonitor XR Controller, navigate to Settings
Menu > Telltale Manager > Telltale info. 2. Navigate to the telltale to be
reset using Next /Prev. 3. Select Config, followed by Reset w/ offset. Follow
the instructions on screen to confirm the
reset. Note: Depending on how the alarms have been configured, this action may
trigger an alarm until the telltale is mechanically reset. 4. The telltale
will now use the current readings as an offset for all future readings. 5. On
the telltale itself, pull the reset handle down
6. Whilst holding the handle down, slide the handle back to the zero position
on the scale.
7. Release the handle. Ensure the handle snaps upwards against the device and
is not stuck in the down position.
8. Pull on each cable coming out of the device to remove slack in the line.

7.2 Controller
7.2.1 Auto-Detect Telltale Network
As described in the commissioning section 6.1 First Power On, the controller
will automatically detect and configure any new telltales connector to the
controller whether a single device or multiple devices. Even if newly
installed telltales are connected to an existing network of telltales that has
already been configured and is recording data, the new devices will be
automatically detected and configured by the controller.
7.2.2 Adding New Telltales
· Telltales can be plugged in live no need to disconnect power from the
telltale network. · The controller will automatically discover new devices and
configure them . · The controller can also configure multiple telltales
dropped on to the system simultaneously. · Set metre marks as described in
section 6.4.
7.2.3 Removing Telltales
· Telltales can either be physically removed or remove via the menu system on
the controller Main menu > Telltale manager > Telltale info > Navigate >
Config > Remove.
· If a unit is physically removed having been previously detected and
configured by the controller, the telltale will appear as inactive. It can
then be removed on the controller via the first step above.
Note: If a telltale is incorrectly removed via the controller, the user must
tell the controller to rediscover the whole network in order to reinstate the
incorrectly removed telltale.
7.2.4 View Live Data
· From the default screen press the right arrow to show displacement readings
as well as telltale information such as serial number, metre mark, status.
· Pressing right again will show telltale supply voltage, current consumption
and temperature as well as any error information.
· By default, the system will automatically scroll through the network,
displaying information for each telltale one device at a time.
· The up and down key can be used to quickly navigate to a particular
telltale. Pressing of the up down button will pause the auto-scroll feature
for 30 seconds to allow the user to navigate to the desired telltale.
7.2.5 Power Outages and Recovery
· If power to the controller is disconnected, then the telltale network will
also lose power. · On reconnection of power to the controller, the controller
will boot as normal and default to
`Load previous setup’ if the network has previously been configured. · There
is an automatic time-out to ensure that this option is selected if no user is
present. · If there hasn’t been a previous setup then the controller will
automatically discover the telltale
network.

Portable Reader
Power on and off
The Reader has a rocker switch on the top cap to allow the device to be
powered on and off to save battery life. Switch this to the ON position to use
the Reader and to the OFF position to power down the device when not in use.
Charging
A charging adapter is provided with each reader. The charger connects to the
reader via the charging connector located on the top of the device. Charging
may only take place in a nonhazardous location. Charging the device fully when
the battery is fully discharged can take up to eight hours.
Power Saving Mode
The unit will automatically shut off the screen and turn itself off after five
minutes of inactivity to conserve power. The unit can be woken up with a
button press.
Commission and Debugging Tool
The portable reader is primarily a commissioning and debugging tool to aid
with installation of the telltale network and help fault find if the network
becomes inactive. Using the reader to check individual telltales on
installation ensures that the devices are working correctly prior to
connection to the controller. The reader also provides a convenient way to set
the telltale metre mark when insitu, ensuring accurate set up of the network
and helping to avoid errors. Primary functions:
· Check line voltage · Check network current · Edit metre mark
Display and Buttons
The display and buttons used are common between the controller and reader
allowing familiar navigation and screen layouts. The buttons are large and
designed to be suitable for use with gloves.
Safety Information
The following precautions are necessary to ensure safe use of the device in
hazardous areas and ensure compliance with certification requirements:
· Do not plug the reader into a network with a controller or reader already
connected. · Do not remove from the leather pouch whilst in the hazardous
area. · Do not attempt to charge the reader in the hazardous area · Ensure
that the integrity of the housing is maintained, checking regularly for dents
in the metal
and cracks in the plastics as well as any other visual anomalies.

RockMonitor XR System User Manual
Maintenance
The maintenance of the product must only be carried out by competent
personnel. Maintenance shall to be considered with reference to the local
safety regulations and authorities. Refer to the following standards for
additional guidance:
· IEC/EN 60079-17 The product shall only be serviced and repaired by Trolex
Ltd., or a local Trolex service agent approved by Trolex Ltd. in order to
maintain the certification of the product.
Visual Checks
Periodical visual checks should be carried out to assess if there are any
issues arising with the Telltales. Check for:
1. Labels on the device are still in place and are not peeling or
discolouring. Ensure all labels are clean by following 8.2 below.
2. Check for any damage to the device. Plastic parts should not be cracked or
broken which could affect IP rating of the device. The metal housing should
not be dented or bent which could cause issues with the mechanical mechanism.
3. Check that the device is still fitted tight against the roof and has not
slipped down in the bore hole.
Cleaning Labels
It is recommended to clean the device periodically to ensure linear scales and
indicators are clean and readable. The product should only be cleaned with a
damp cloth.
Check Mechanism for Seizure or Jamming
Periodically check that the spring mechanisms on the displacement indicators
are able to move freely. This can be done by pushing each indicator forward a
little and releasing. The indicator should slide back freely to its original
position and not stick in place.
Inactive Telltales
Inactive instruments can be viewed either via the Trolex|Core application
software or directly on the controller. If an inactive instrument cannot be
recovered, then it should be removed from the network.
Replacing Telltales
The telltale is designed to be a one-time fit into the bore hole, due to the
retention required to hold the device in place. If a faulty instrument does
need to be removed from a bore hole, then this is possible, but it would
require a high degree of force to extract. Take any relevant precautions when
doing this to minimise the risk of injury.
P5625.1600 Rev E 40
System Troubleshooting and Diagnosis
Faulty Telltales
· Telltale devices displaying faults will either appear as inactive on the
controller or not appear at all.
· If a device displays as inactive or cannot be found, try disconnecting and
reconnecting the telltale to the network.
· The portable reader can also be used to connect directly to telltale,
allowing checking of the voltage and input current to ensure they are within
acceptable limits.
· If disconnecting and reconnecting of the telltale does not solve the issue,
then please contact Trolex for technical support.
Short Circuit (Telltale Network)
· If a short circuit is detected by the controller, the screen will display
short circuit detected’ and automatically disconnect power to the telltale network. · Depending on the option selected in main menu > system > short circuit reset, the controller will either displayPower will auto-reset’ and attempt
to automatically recover periodically or display `Power latched off’ and give
the user the option to attempt to recover the network.
· If short circuit detection is set to latching, the controller will turn off
power to the network and remain off until an operator manually power cycles
the controller.
· If the short circuit has been successfully resolved, then the controller
will resume with the previous configuration.
Reset Handle
The reset handle is part of a spring-loaded mechanism designed for releasing
the handle from the anchor wire to allow it to be moved back to zero.
· If the reset handle is difficult to pull down it is not recommended to apply
too much force to pull it. Use one hand to brace against the metal body of the
device and another to pull the handle down.
· If the handle does not snap back into the up position it could also be due
to dust ingress. Do not leave the handles stuck in the down position as this
means the anchor wire may not be clamped and displacement may not be measured.
The handles can be pushed up manually if required, once they are against the
body of the device the anchor wire will be clamped.

RockMonitor XR System User Manual 9.4 Cable Length Too Long / Too Many
Instruments on the Line
The RockMonitor XR system is designed to work over long distances with many
telltale instruments connected in a single system. However, system performance
and the ability to support multiple instruments reduces rapidly over extended
cable runs. The system protects itself via an undervoltage lockout mechanism
implemented in the controller. If the too much current is drawn, and the
voltage drops below the defined threshold then the controller will turn-off
power to the telltale network. The graph and table below show how many
telltales can be supported at a given distance.
If the number of telltales required for the application exceeds the values
shown above, it may be feasible to install a second controller and split the
network to reduce the load on the first.
