Safety Markings and Symbols
STRONG MAGNETIC FIELD - The wheels of the scanner contain magnets that produce an extremely
strong magnetic field which may cause failure or permanent damage to items such as watches,
memory devices, CRT monitors, and medical or other electronics devices.
Strong magnetic fields pose a variety of risks, especially to people who wear implanted cardiac devices
like pacemakers and defibrillators.
RISK OF FINGER TRAP - Tools, magnets, and metal objects can cut, pinch, or entrap hands and fingers.
HANDLE WITH CARE.

1. On Board Controls
Use this button for Pause / Resume or Increment / Encoder Reset functionality (depending on hardware
setup). See LYNCS WI and LYNCS CM overviews for hardware setups.
2. Scanner Frame / End Caps
Scanner frame: Used to mount the tractor units, tool posts and corrosion mapping mount.
End Caps: Remove end caps via two captive thumbscrews to insert / remove the tractor units, tool posts or
corrosion mapping mount.
3. Electronic Tractor unit
Electronic tractor unit assembly. Houses the button and the encoder.
4. Encoder Umbilical Socket
Connect the encoder cable to this socket to provide communication back to the instrument.
5. Encoder Cable Strain Relief Point
Used to provide strain relief on the encoder cable.
Prior to use, ensure the encoder strain relief is applied. Failure to do so could result in encoder cable or
tractor unit damage. Do not use strain relief points to tether unit.
6. Tractor unit clamping mechanism
Used to hold tractor unit in place on scanner frame.
Loosen off thumbscrew to adjust tractor unit position.
Tighten thumbscrew to lock tractor unit in place.
7. Mechanical Tractor unit
Mechanical tractor unit assembly. Contains no electronics.
8. Umbilical Assembly Strain Relief Points
Used to provide strain relief on the umbilical cable assembly. Do not use strain relief points to tether
unit.
Ensure the strain relief is applied correctly to the umbilical assembly as shown below. Strain relief chain
must be applied to the scanner centrally and allow for sufficient relief on the cables:

7
Prior to use, ensure the umbilical strain relief is correctly applied as described above. Failure to do so
could result in damage to the assembly.
9. Encoder
Records the distance travelled.
10. Handles / Tether points
Handles: Used to deploy, move and remove the scanner.
Ensure the handles are used at all times when handling or operating the scanner.
Tether Points: Ensure the unit is tethered centrally to each attachment point at all times to prevent the
scanner from falling. Prior to use, ensure the end caps and each tractor unit are securely fastened on the
scanner rail.
11. Wheel Brakes
Used to hold the scanner in position.
To engage brakes: Turn levers up, facing away from the inspection surface.
To disengage brakes: Turn levers down, facing towards the inspection surface.
Ensure brakes are disengaged (levers down) prior to moving the scanner. Failure to do so will result in
accelerated wear of the brake teeth.

1. Outer Tool Posts
Wedge tool posts that mount to the outside of the scanner frame. Outer tool posts have a single rail
mounting point.
2. On Board Controls
Use this button for Pause / Resume functionality.
To use Pause / Resume functionality, ensure encoder cable is plugged directly into the instrument and
scanner. Do not connect the adapter cable. Connecting the adapter cable will enable Increment / Encoder
Reset functionality. *Adapter supplied with LYNCS-FULL, LYNCS-CM.
3. Tool Post Clamp
Used to hold the tool post in place.
To engage tool post clamp, turn lever up to vertical position:
To disengage tool post clamp, turn lever down to horizontal position:
Ensure tool post clamps are disengaged (levers down) prior to moving the tool post.

11
4. Inner Tool Posts
Wedge tool posts that mount to the inside of the scanner frame. Inner tool posts have a rail mount on
either side of the tool post.
5. Tool Post Tilt Adjustment
Used to tilt outer tool posts forwards for lower diameter pipework.
To tilt the tool post forwards, loosen thumbscrew and move to desired position:
Tighten thumbscrew to lock tool post in place.
During setup, ensure outer tool posts are in vertical position (un-tilted) to ensure ease of wedge setup.
Tilt tool posts forwards when on the inspection surface.
6. Removable central handle
Accessory which can be mounted to scanner rail to aid stability and maneuverability.
Do not remove scanner from the inspection surface using the removable handle. Removable handle is not
intended for this purpose. Please use the scanner handles to remove scanner from the inspection surface.
7. Cable guides
Accessory which can be mounted to scanner rail to aid cable and water hose management. There are two
different types of guides; C-Type & D-Type. C-Type are typically for larger diameter probe leads and D-Type
are typically for water hose and smaller diameter probe leads.

12
8. Tool Post Arms / Wedge Mounting Points
Used to mount varying wedge widths.
To adjust the width of the tool post arms, loosen thumbscrew at rear of tool post and move arm to desired
position, tighten thumbscrew to lock tool post arm in place:
Threaded holes are used to receive 5mm and 8mm diameter wedge mounts (1 & 3).
Non threaded holes are used to receive wedge sets with a 5mm diameter pin (2).
