Description
The Inuktun Minimag™ is a magnetic tracked crawler capable of driving vertically or horizontally inverted
along ferrous (iron based) surfaces. Additionally, the magnet modules allow the vehicle to pull longer
lengths of tether than what could normally be achieved without magnets when travelling in steel pipes or
on steel decks. The crawler has mount points for two Crystal Cam® cameras, a Spectrum 90™and two
101 lights. The vehicle uses two 6000 series Minitracs™for motive power that are mounted underneath
the main chassis plate. The vehicle uses two powerful rare earth magnet modules that can be moved up
and down to accommodate different pipe diameters and strength requirements.
This Minimag is intended to be controlled with a Versatrax™power supply/controller.

•All personnel operating or maintaining this equipment must read and understand the operations
and maintenance manual prior to system operation.
•All personnel operating or maintaining this equipment must be competently trained.
•Appropriate personal protective equipment (PPE) must be worn while operating and maintaining
the equipment.
•Caution:Spark Hazard. Under no circumstances should this equipment be used in a potentially
explosive atmosphere.
•Caution: High Voltage. The tether carries 72VDC and 120VAC to the rear harness block; the
track and camera whips carry 72VDC from the harness block, and the light whips carry 120VAC.
Keep the tether capped at all times when not installed on the vehicle. Follow the guidelines for
preventing tether damage. Do not operate with a damaged tether or device whips.
72VDC/120VAC can cause serious injury or death. Repair damaged wires before operating the
vehicle. A short circuit may damage the controller, cameras, or any attached equipment.
•Disconnect the power source before servicing the product; otherwise, damage or fatal injury may
result.
•Caution: Trip Hazard. Never stand on the tether. The vehicle and winch are strong enough to
pull it out from underneath you and cause you to fall. Standing on the tether may also cause
damage to the internal conductors and decrease the life of the protective jacket.
•Caution: High Temperature. Both the integrated harness block and the Minitracs™ may
become extremely hot during operation. Always wear protective gloves when handling these
parts of the vehicle after they have been in use.
•Caution: Intense Optical Radiation.The 801 lights and Spectrum™ camera lights are
extremely bright. Never look directly at the lights or even from a shallow angle. Always use a
welding filter (shade #8 or higher) when inspecting the LEDs.
•Caution: Pinching Hazard.There is a possibility that one’s fingers could be drawn into the
tracks should they be activated when the vehicle is being handled. To avoid this hazard do not
connect the tether to the portable controller until the vehicle is configured, placed and ready to
use. If the vehicle is being tested, do not connect the tether until handling of the vehicle is
complete. If the vehicle is permanently installed onto a van or trailer and the tether cannot be
disconnected, turn off the power.
•Establish a communication protocol between the person handling the vehicle and the operator at
the computer. It is the operator’s responsibility to check and ask if it is safe to power up the
vehicle or initiate movement.
•Caution: Extreme Magnetic Field. The magnet modules can induce a large enough force to
sever fingers! Always keep vehicle away from ferrous objects and keep hands clear of the
magnets. Also keep any sensitive electronic or magnetic devices away from the vehicle.

The portable controller is to be used in a dry, covered environment only. These components are not
waterproof. Keep all cords and cables away from water. The recommended controller and power supply
operating temperatures are between 0 ˚C – 50 ˚C (32 ˚F –122 ˚F).
The tether and vehicle are depth rated to 60 metres (200 feet) of water. The tether connector is a dry-
mate type which must be dry when connected to the vehicle. Keep the tether connector capped with a
dummy plug when not connected to the vehicle to help keep out dirt. The tracks are tolerant to sandy and
muddy conditions, although this decreases seal life. The vehicle may also be operated in dry or dusty
environments in the recommended operating temperature range of 0 ˚C – 50 ˚C (32 ˚F –122 ˚F).
System storage temperatures are between -20˚C - 60˚C (0˚ F - 140˚ F).
System Power & Line Voltage Set
Power Requirements
Line Voltage: When installing the system in a new location always check the line voltage selection switch
located next to the AC power cord on the controller. This switch may be set for 110VAC or 220VAC
power input and must match the line voltage of the power source. Incorrectly setting this switch will
damage the controller.
If your system includes a powered cable winch refer to the winch manual for instructions on setting its
input voltage. An incorrect voltage at the winch will damage the motor controller.
FIGURE 1: AC LINE VOLTAGE SELECTION
Power Requirement: The following figures are for a 1500-foot system and take component efficiency
and tether power loss into account.
Vehicle and Controller = 800W. Winch = 1000W. Total system = 1800W peak load.
With no winch the system can operate comfortably on a 1000W supply or inverter. With a full system we
recommend a minimum of 2000W supply or inverter. Remember to account for the power used by your
monitors and video recorders.

User Manual
The Versatrax™ controller is designed to support our tracks, cameras, and lights. Powering other
devices or equipment off the Versatrax controller is not recommended.
Generators / Inverters
If powering the system from a generator or inverter, refer to that unit’s operating manual for
recommendations on continuous and peak load ratings. These power sources may apply a reduced
output rating based on electrical load and environmental temperature. Remember to include the power
needs of any other connected devices (external monitors, recording devices, lighting, etc.) when selecting
a generator or inverter.
Video Hook-Up
The external video connectors on your Versatrax system use RCA style video jacks similar to most
monitors and video equipment. An RCA style video cable has been supplied with the controller. Some
industrial monitors may use a BNC style video jack. An RCA to BNC adapter has been supplied for this
purpose.
Video from your Versatrax controller may be connected directly to the video input of a television, or other
recording device. Please refer to your television or recording device owner’s manual.
Winch Installation
If your system includes an AC powered winch, refer to the winch manual for installation instructions.
Auxiliary Device
There is provision in the Versatrax system to allow add-on devices such as a rear facing camera, sonar,
or other vehicle electronics. A twisted pair in the tether is reserved for telemetry from this device. The
controller must be configured by setting a dip switch on the main control PCB (see Figure 4 below). The
standard configuration is to use this twisted pair for the rear camera.
•If the vehicle has a second camera, set the auxiliary dip switch to the position marked “rear
video”. This is the default position shipped from the factory. The switch must be in this position
in order to receive video from a secondary camera.
•If the spare conductors are to be used by other devices, such as sonar or on-board sensors, the
switch must be set to the position marked “spare cond.” This will route the signals to the
“Desktop Controller” connector on the controller.

FIGURE 2: AUXILIARY DIP SWITCH
Vehicle Tether Connection
It is very important to properly connect the tether and strain relief to the vehicle. Improper connection
may result in costly tether damage. See the figures below.
1. The tow cable must be securely attached to the harness block.
2. The other end of the tow cable clips to the Kellems grip strain relief. Ensure the Kellems grip is
adjusted properly to allow some tether slack as shown.
3. Plug the connector all the way in. It is important for the longevity of the connector that it be kept
free of dirt, have good o-rings and be mated carefully.
4. It is important to adjust the Kellems grip to allow slack in the tether connection, no matter what
angle the tether approaches the vehicle.
5. Tether connection to the parallel, and in-line vehicles are identical.
6. When the tether is not plugged in, it should be capped to prevent dirt and moisture from entering
the pins.

Magnet Removal/Installation
The Minimag™comes equipped with two extremely powerful magnet modules. It is recommended that
these modules remain on the vehicle to minimize handling and potential injury. If they must be removed
take the following precautions:
1. Keep any sensitive electronic or magnetic devices away from the magnets
2. Work in an area away from all ferrous materials to minimize the risk of accidental magnetic
adherence
3. Always store magnet modules away from each other and never bring them into contact with each
other.
Warning: Magnet modules pose a serious pinch hazard and may become permanently attached if
allowed to make contact.

User Manual
The Minimag™ vehicle uses two very powerful permanent magnet modules to adhere the vehicle to a
wall or pipe. In order to change the magnetic adhesion force, the spacing of the magnets away from the
driving surface can be changed by using the following procedure:
1. Loosen the magnet height adjustment locking screws (4x M5 SHCS).
2. Tighten (increase height / decrease force) or loosen (decrease height / increase force) the
magnet adjustment screws (4x M8 HEX BOLTS) by a half turn at a time, in a star pattern across
the four corners.
3. Once the desired height is reached, re-tighten the magnet height adjustment locking screws.
FIGURE 4: MAGNET SPACING ADJUSTMENT
If the vehicle is being driven inside a pipe, the magnets should be lowered to account for the specific pipe
diameter. All situations are unique and thorough testing should be done to make sure the vehicle will
remain adhered to the wall in all situations before inspections are undertaken.
Conversely, the magnets should be raised if driving on the exterior of a pipe. Again, thorough testing for
adherence is recommended prior to a full inspection.
The minimum pipe diameters for both internal and external driving is estimated at 3m (120in).

It is recommended to use spring replacement blocks on the Minitracs™ due to reverse tensioning of the
belts during tight pivot maneuvers. See the user manual for the Minitrac for more information regarding
spring replacement blocks.
When the Minimag™ vehicle is operating in a vertical position, the downward force on the chassis due to
the weight of the Minimag may cause the Minitracs to back-drive and creep down the vertical surface.
Loss of power to the system will cause the Minitracs to quickly descend a vertical surface. The Minimag
vehicle can be ‘parked’on a vertical surface by orientating the tracks sideways instead of up/down.
Warning: The Minitracs™ on the vehicle may back-drive and creep downwards while operating on a
vertical surface.
Light/Camera Installation
The vehicle comes with two 101 flood lights and the option for an Spectrum 90™camera mounted into an
integrated mount assembly. There is also a mounting location for a pivoting rear facing Crystal Cam®
and an optional forward-facing Crystal Cam® if the Spectrum 90 is not used. The SP90/light mount can
be located in multiple positions.

To remove the Spectrum™camera, disconnect the connector whip and remove the 3x ¼-20x5/8 SHCS
at the rear of the mount –the camera may then slide forward and away from the mount.
To adjust the position of the mount camera and light mount the Spectrum camera must first be removed.
With no camera installed remove the 4x M5x18 SHCS from the base of the mount and slide the mount
forward or backward to the desired position; re-install with the M5 SHCS.
A camera video adaptor whip is provided to support the optional forward-facing Crystal Cam®. The
connector whip labelled ‘CC Video Adaptor’ must be installed in-line with the camera whip for the forward-
facing Crystal Cam® to work.
FIGURE 7: CRYSTAL CAM® MOUNTS
The main chassis plate has locations on the front and back for optional Crystal Cam®. To mount and
adjust the cameras do the following:
1. Install the camera mount onto the chassis plate using the M5 SHCS.
2. Pivot the bracket into the desired position and tighten the M5 nut.
3. Install the Crystal Cam® using 2x #6-32x5/8 SHCS –make sure camera orientation is correct
(there is a ‘TOP’ label on the camera)

FIGURE 8: PAYLOAD CALCULATION
The maximum payload calculation is based on the magnet’s ability to resist the gravitational moment (or
torque) induced at the driving surface. When payload weight and/or distance from the wall is increased,
the vehicle tries to pivot away from the wall and the magnets resist this moment. When the maximum
payload moment is exceeded, the vehicle may fall off the driving surface during operation. The payload
moment may be calculated as follows:
𝑀 = 𝑊 × 𝐷 ≤ 4.5kgf · m [400lbf · in]
Where W is the weight of the payload, and D is the distance of the centre of gravity of the payload from
the driving surface. Note that the chassis and tether weight has already been accounted for and does not
have to be included in customer payload.
The above calculation is for operation on flat surfaces. Payload calculations are de-rated for operation
on curved surfaces.

Fall Arrest
Due to the weight of the Minimag™ vehicle, the Minitracs™ will back drive and not hold the position of the
vehicle during power loss or power shutdown. A lifeline or fall arrest system should be used at all time
when the vehicle is navigating on a vertical or inverted horizontal position.
A Kellems grip (wire mesh grip) on the tether has been provided to attach a fall arrest system. Another
optional fall arrest attachment point is the top handle of the SP90/light mount.
Warning: Fall arrest system should be used during vertical or inverted horizontal operation.
Tether Handling
The tether should be considered the most important part of the vehicle system. It feeds power and
control signals to the vehicle and returns data from the sensors. If the tether becomes damaged from
improper use, poor handling or an accident, the vehicle may become crippled or inoperable. This is a
serious situation because of the cost for tether repairs, as well as significant downtime and loss of
production. For maximum tether life and reliability, we offer the following tether handling tips:
Never step on the tether. Trampling the tether may crush conductors, leading to premature failure.
Trampling is also abrasive to the tether jacket. Trampling fosters the wrong attitude toward the tether.
Remember, this is an expensive multi-conductor tether, not a common electrical extension cord.
Never allow vehicles, trucks, cars, etc. to drive over the tether. This will do concentrated, immediate and
permanent damage. Set up cones or blockades to keep vehicles away.
Do not bend the tether beyond its minimum bend diameter. If the tether has difficulty bending, you have
bent it too far. If the tether is bent beyond its minimum diameter on pulleys or around corners, wire
fatigue will be accelerated. It is important that any pulleys or tackle support the tether at or beyond its
minimum bend diameter. For an extended fatigue life, the minimum bend diameter should be considered
larger.
Note: For the standard Minimag system, the minimum tether bend diameter is 250mm (10in).
Never kink the tether. A kink will permanently bend a cable and may break a wire or fibre internally. Take
precautions to never allow the tether to kink. Kink situations may occur when there is slack tether with
closing loops, or when coils slip off a full drum.
Do not snap load the tether. Your tether has a maximum safe working load of 200kgf (450lbf) of tension.
Loads may peak at a very high value when the tether snaps taut. Snap loading may easily occur when a
slack tether is reeled onto a motorized spool, or when the vehicle is suspended from a swinging
deployment crane.
Avoid loading the tether unnecessarily. Unnecessary large loads will only shorten the fatigue life of the
tether.
Never fully un-spool the tether. The surface end of the tether is anchored to the spool drum. If the spool
is turned past the anchor point, the tether may be kinked or broken and require re-termination. To help
prevent this, a band of tape is typically wrapped around the last few coils to act as a visible and audible
warning that the tether is fully paid out.

Connector Handling
With regards to system reliability, connectors come next after the tether in terms of importance. Though
not quite as expensive to replace as a whole tether; a damaged connector can still represent significant
cost in downtime and re-termination which could easily have been prevented. To this end, we
recommend the following steps to help prevent damage to connectors.
When plugging in a connector:
•Inspect for dirt in both sides of the connectors. Do not plug in a dirty or damaged connector.
•Inspect for bent or burnt pins.
•Visually align the key-way or locating pin first before plugging in. Do not blindly jam and twist.
•Fully tighten or engage a connector. Never use a connector partly plugged or screwed in.
Contacts left partly open may be subject to leaking, arcing, and burn-out.
•Use locking collars where available. In general, locking collars need only be screwed on finger
tight.
•In general, all connectors on the vehicle are wet pluggable.
•Install dummy plugs on unused connectors.
•Regularly apply silicone grease to the connectors to keep them from seizing.
•Never use WD-40 or similar solvent-based fluids as this can cause serious damage to
connectors.
Shipping
The Minimag™ vehicle uses two very powerful permanent magnet modules to adhere the vehicle to a
wall or pipe. Always use a steel box to shield magnets during shipping.
Warning:Always use a steel box to shield magnets during shipping.

Ensure that all fasteners are in place and secure. In particular, check the fasteners holding on
cameras, lights, tracks, and the harness block.
Visually inspect the vehicle and Minitracs™ to ensure that the moving parts are free of debris and
functional. Make sure the track belt is free of debris and turns freely.
Check the tether and vehicle whips for damage.
Ensure camera, light, and laser ports are clean.
❑Check the reel for the following:
Check that nothing will block movement of the level wind shuttle.
Check that the tether has no loose, dangling coils. Dangling coils can propagate as the drum
rotates and have the potential to jump the drum. Take care of these before deploying the tether.
❑Check fall arrest system.
❑Power up the system and check the following:
Check for sufficient SSD drive space for recording.
Check record directories are set.
Test video recording.
Test laser lines.
Test auxiliary lights.
Test track control.
Test camera control.

Post-Operations Check
A Post-Ops inspection should be carried out after every deployment using the following checklist:
❑Inspect the tether for damage as it is reeled in.
❑Visually inspect vehicle for entrained debris or mechanical damage.
❑Test each function to ensure proper operation.
❑Clean the system by hosing it down with water at regular line pressure. Do not pressure wash. The
tracks may be cleaned off by hosing them down while running. If the system has been used in salt
water, thoroughly rinse the vehicle with fresh water right away.
❑Take time to pack the system properly for transport away from the worksite.
❑Store the system in a dry environment.
Note: Ensuring the Minimag™ system is always stored in good working condition will minimize
deployment time for future inspections.
Caution: Use regular water line pressure to rinse. Do not use a pressure washer. The high-pressure
water jet can push past the seals.
Power-Up Sequence
Make sure all the equipment is properly connected before powering up. Once turned on, the controller
will run through a brief power up cycle. A start-up screen (discussed in the next section) will display
choice of crawler type and tether length. When this screen is cleared, the controller is ready for
operation.
If the system power is cycled off and back on quickly, the video overlay may not initialize properly. If this
occurs, turning the controller off for five to ten (5-10) seconds will allow the display to reset itself.
Always power the system down before connecting or disconnecting any equipment. In particular, never
connect or disconnect the camera with the power on.
