Swift Overview
Batteries
Swift can be used under battery power. It is designed with two battery cradles under the
protective battery compartment door, but can be powered by a single battery. Swift uses
Li204SX-7800 lithium-ion rechargeable batteries from Emerging Power, which do not suer
from the memory eect aecting previous generations of batteries. Each battery has an
‘always on’ 5 bar LCD state of change bar graph to indicate estimated remaining battery
life.
WARNING!
When transporting Swift, it is the responsibility of the user to ensure the safety precautions
used are in accordance with the local department of transportation (or equivalent governing
body) rules and regulations.
When carrying or transporting Swift in its transit case, remove the batteries from the
instrument and ensure they cannot come in contact during transport, as this poses a
signicant re and explosion hazard. Swift transit case comes with slots tted to receive
the batteries once removed from the instrument.
Do not replace the batteries for any battery other than Li204X-7800 lithium-ion rechargeable
batteries from Emerging Power
Inserting/Removing Batteries
Inserting Batteries
1. On the left side of Swift, unlatch the battery compartment door, then open.
2. Align your battery with one of the battery cradles.
Note: Battery cradles are marked A and B. If inserting only one battery it does not matter
which cradle is used.
3. Make sure that the battery contacts are facing inward and upward.
4. Slide the battery into the battery cradle until it is fully inserted.
5. Close the battery compartment door and secure the latch.
Removing Batteries
1. On the left side of Swift, unlatch the battery compartment door, then open.
2. Grab the battery tab between thumb and forenger.
3. Pull on the tab to release the battery contacts.
4. Slide the battery out of its cradle.
Hot Swapping Batteries
It is possible to remove one battery from Swift when it is powered on as the instrument can
operate on a single battery. If the power in the remaining battery is insucient to keep
Swift powered on, the instrument shuts down without damaging electronic components.
Any work in progress in Swift software (acquisition, etc.) is lost.
Battery Charging
Swift batteries recharge automatically when they are in the instrument and the AC adaptor
is connected to the power outlet and turned on. The battery indicator on the lower-left
keypad displays information about the battery charge. Swift software also features a
battery charge indicator.
Note: Batteries do not recharge when their internal temperature exceeds 45°C (113°F).
Batteries also do not power Swift when the instrument’s internal temperature exceeds 55°C
(131° F).
9 | www.silverwingndt.com
Page 22
Using the Battery Charger
Note: Swift batteries can also be charged in an external battery charger. This charger
conditions and calibrates the instrument’s batteries, which is important in maximizing
battery life.
Figure 1–8 Optional battery charger
Status window
Calibration buttons
Battery slots
To charge the batteries with the optional charger:
1. Place the charger on a at and level surface, away from heat and moisture sources.
2. Insert the power supply’s DC connector into the back of the external charger.
3. Connect the power supply to an AC supply using the supplied cable.
All the LEDs ash momentarily to let you know that power is present.
Swift Overview
4. Insert the batteries into the battery slots while making sure that the contacts are fully
seated.
The charger automatically begins charging the batteries and the LEDs in the status
window display the following information:
• Flashing green: battery charging
• Green: battery fully charged
• Flashing blue: battery calibrating
• Blue: battery charge gauge calibrated
• Flashing red: battery charge gauge in need of calibration
• Red: error
Calibrating Batteries
To ensure that your batteries perform at their full capacity for the longest possible time, it
is important to calibrate them on a regular basis. Calibration involves a standard battery
charge followed by a deep discharge, and then a complete charge.
It is recommended that batteries are calibrated every six months. This procedure usually
takes 10 to 13 hours, whereas a standard charge only takes approximately 3.5 hours.
To calibrate batteries, place them in the charger and then press the calibration button.
Storing Batteries
Whenever transporting Swift in its case, remove the batteries from the instrument, place
them in plastic bags and ensure they cannot come into contact during transport since they
pose a signicant re and explosion hazard.
Swift transport case is outtted with two slots intended for the batteries. We recommend
that they are taken advantage of.

Batteries
Inserting/Removing Batteries
Scorpion2 uses an NH2054 HD31 14.4V Lithium Ion smart battery from Inspired Energy. Each
battery has an ‘always on’ 5 bar LCD state of change bar graph to indicate estimated
remaining battery life.
WARNING!
When transporting Scorpion2, it is the responsibility of the user to ensure the safety
precautions used are in accordance with the local department of transportation (or
equivalent governing body) rules and regulations.
When transporting Scorpion2 in its transit case, remove the batteries from the crawler and
ensure they cannot come in contact during transport, as this poses a signicant re and
explosion hazard.
Scorpion2 transit case comes with slots, tted to receive the batteries once removed from
the crawler.
Note
Do not replace the batteries for any battery other than NL2054 HD31 Lithium-Ion batteries
from Inspired Energy.
Inserting Batteries
1. On the lid of Scorpion2, unscrew the four thumb screws and remove the battery
compartment lid.
2. Make sure that the battery contacts are facing inwards and downwards.
3. Secure the battery compartment lid using the thumb screws.

Scorpion2 Overview
Battery Charging
Scorpion2 batteries must be charged using the external battery charger. This charger
conditions and calibrates the instrument’s batteries, which is important to maximize their
lives. We recommend calibrating the batteries every six months.
Figure 2–6 Battery charger
Status window
Calibration buttons
Battery slots
To charge the batteries with the charger:
1. Place the charger on a at and level surface, away from heat and moisture sources.
2. Insert the power supply’s DC connector into the back of the external charger.
3. Connect the power supply to an AC supply using the supplied cable.
All the LEDs ash momentarily to let you know that power is present.
4. Insert the batteries into the battery slots while making sure that the contacts are fully
seated.
The charger automatically begins charging the batteries and the LEDs in the status
window display the following information:
• Flashing green: battery charging
• Green: battery fully charged
• Flashing blue: battery calibrating
• Blue: battery charge gauge calibrated
• Flashing red: battery charge gauge in need of calibration
• Red: error
Calibrating Batteries
To ensure that your batteries perform at their full capacity for the longest possible time, it
is important to calibrate them on a regular basis. Calibration involves a standard battery
charge followed by a deep discharge, and then a complete charge.
It is recommended that batteries are calibrated every six months. This procedure usually
takes 10 to 13 hours, whereas a standard charge only takes approximately 3.5 hours.
To calibrate batteries, place them in the charger and then press the calibration button.
Storing Batteries
WARNING
Whenever transporting Scorpion2 in its case, remove the battery from the crawler, place
them in plastic bags and ensure they cannot come into contact during transport since they
pose a signicant re and explosion hazard.
Scorpion2 transport case is outfitted with two slots intended for the batteries. We
recommend that they are taken advantage of.

Introducing Swift Software
Running on Swift is a powerful, easy-to-use data acquisition and analysis software. It is
specically designed for B-Scan ultrasonic inspections and relies on an intuitive wizard to
congure setups.
The software benets from a graphical user interface (GUI) designed to simplify the
inspection process. The multi-touch display is the best way of interacting with Swift,
however a USB mouse can keyboard can be connected, if required.
On the left hand side of the GUI is a sidebar that provides access to the various windows
associated with the setup and progression of an inspection, the inspection setting
preferences and status information regarding Swift. A toolbar menu with window specic
operational buttons is located at the top of the GUI.
Home
Home allows either a new inspection to be created or a saved inspection on Swift to be

Inspecting on Slippery, Damp or Wet Surfaces
Slippery conditions will compromise the performance of the crawler. If the inspection
surface is slippery, then it is recommended to not drive the crawler or perform an inspection
at its maximum speed of travel.
Scan Path
Visually check the scan path of the crawler and identify if any obstructions exist. Driving
over obstructions could cause the crawler to slip or be dislodged from the inspection
surface.
Ensure there are no areas of non-ferrous material along the scan path. Driving across nonferrous material results in a loss of magnetic attraction that could cause the crawler to slip
or be dislodged from the inspection surface.
When operating Scorpion2 at height, cordon o an area of at least 6m, [20ft] in all
directions directly below the intended scan path.

A-Scan Conguration
Capturing accurate and reliable thickness gauge data requires:
1. Correct transducer selection. Scorpion2 scanner is tted with a 5MHz twin crystal
transducer.
2. An accurate reference block of the same material as that being tested. The calibration
or reference block should be made of material with the same sound velocity and
attenuation characteristics as the material to be inspected. It should have parallel
machined surfaces representing the thickness range to be inspected. A minimum of two
thicknesses representing the minimum and maximum values is acceptable for calibration,
however it is recommended that the calibration block has four dierent thickness
sections to cover the expected thickness range to allow for verication of the calibration.
3. Correct ultrasonic calibration on Swift. The aim of the calibration is to set the ultrasonic
parameters to clearly view the echoes and position the gates to read the correct
material thickness.
A-Scan Calibration
It is possible to calibrate using only one known material thickness. However it is recommended
to verify the calibration across a range of known thicknesses.
To conduct a manual A-Scan calibration:
1. Place the transducer onto the calibration block.
2. Tap A-Scan Conguration to access the A-Scan Conguration window.
Figure 5–4 A-Scan conguration
3. Set Crystal so that it matches the transducer connected to Swift.
4. Set Filter so that it matches the transducer connected to Swift.
5. Set Velocit y to the material velocity under test.
Note: The velocity for mild steel is 5960 m/s [0.234 in/us].
6. Adjust Range and Delay so the echoes from the desired thickness range can be viewed.
It is recommended to view no more than three back wall echoes and that the rst back
wall echo is positioned along the time base value that corresponds to the material
thickness.

Acquisition Mode
A suitable acquisition mode must be selected in order for Scorpion2 to perform a scan. The
available modes are:
• Automatic mode
Scorpion2 drives automatically and relies on both encoders to actively steer during the
scan to ensure it travels in a straight line.
Note: Surface condition and scan direction can aect steering accuracy.
When conducting an automatic scan, details of a scan oset, scan length, scan
direction and scan speed must be entered prior to a scan.
• Manual mode
Scorpion2 is driven by either using Swift joystick or by holding the nudge forward and
backward button on Swift, and relies on the right hand encoder to record the distance
travelled. When conducting a manual scan, details of a scan oset must be entered
prior to a scan.
The maximum distance the crawler can travel in one scan is 50m (164 ft).
If the battery level of Scorpion2 is 15% or below the crawler is prevented from performing
an inspection. When attempting to inspect, a warning message is displayed. Scorpion2 can
still be driven using the joystick, but in order to continue the inspection, the battery in
Scorpion2 must be changed.
CAUTION!
If the battery level of Scorpion2 is 15% or below, the system prevents any scanning. To
continue, change the battery in Scorpion2.

Troubleshooting and Maintenance
Maintaining Swift
Because of its design, Swift instrument only requires minimal maintenance. Since Swift has
no moving parts, it also does not require any preventive maintenance. We recommend a
regular inspection of the instrument to ensure that it is properly grounded. We also strongly
recommend that an annual calibration and a factory-performed preventive maintenance
is conducted by an ocially qualied Eddy technician.
Cleaning Swift
It is recommended that the instrument is cleaned after every inspection.
1. Make sure that the instrument is o and that the AC power adaptor is disconnected.
2. To bring the instrument back to its original nish, clean it with a soft cloth.
WARNING!
Do not spray the instrument with chemical cleansers or water. Doing so may lead to short
circuits and damage to the instrument.
Important
To remove stubborn stains, use a cloth moistened with soft, soapy solution. Do not use
abrasives or strong solvents as they could damage the nish. Wait until the instrument is
completely dry before connecting the power cord or cables.

Troubleshooting and Maintenance
Known Issue With System Updates/Upgrades
On some units, a blue Windows error screen may appear when you attempt to enter the
system recovery, which can cause the unit to start normally. Try performing the update
procedure again.
Troubleshooting
Troubleshooting System Updates/Upgrades
• No update le found. This appears in the update list or in the system recovery. Make
sure that you only have one USB mass storage device connected to Swift. Also make
sure that the le is in the root folder of the device.
• Cannot display the options screen. You do not press and hold the nudge forward
button and the change layout button long enough, you do not press and hold the
correct buttons, or you do not press and hold the buttons quickly enough after turning
on Swift. Try holding the power button for two seconds, and then quickly pressing and
holding the nudge forward button and the zoom out button.
• Using the system recovery method. Swift restarted normally or a blue error screen
appeared on the screen. Perform the procedure again.
• Unable to activate Windows. Make sure that your Ethernet cable is sound. Make sure
that you have Internet access. Make sure you are using DHCP. Turn on Swift after
connecting the Ethernet cable and network. If you do not see a message warning you
that Windows is not activated when it starts, Windows is activated.
Scorpion2 Crawler Maintenance
Scorpion2 crawler is designed for minimal maintenance. After each inspection, it is
recommended that, due to its moving parts, some preventative maintenance and cleaning
around critical components is required. We also strongly recommend that an annual
calibration and factory-performed preventive maintenance is conducted by an ocially
qualied Silverwing technician.
WARNING!
Do not attempt to unscrew and remove the lid of Scorpion2 crawler. This can compromise
the integrity of the seal and cause damage to internal components. Damage to the seal or
removal of the lid will void the manufacturer warranty.
Drive Wheels
Clean any build-up of debris in the treads of the four drive wheels. Also clean any build-up
between the wheels and the crawler chassis. During use on wet or dusty surfaces, the
wheels may spin and become polished. If they do become polished, lightly roughen the
surface with 120 grit emery cloth.
Encoders
Clean any build-up of dirt around each encoder wheel. Check there is sucient spring
pressure to keep the encoder wheels in contact with the surface at all times. Ensure the
encoders do not get damaged during use, as it could cause issues with the automatic drive
and steering of the crawler as well as distance measurement inaccuracies.
Cabling
Check all cabling for any damage that could have been caused during use. Do not walk,
stand, trap or place objects on top of the umbilical cable. If a cable is damaged, do not use
until it is repaired.

Troubleshooting and Maintenance
Dry Coupled Wheel Probe
Remove the wheel probe for further maintenance and replace the cleaning pad when there
is a build-up of debris.
Wear Runners
Clean any build-up of dirt around the wear runners. Check the surface for any damage or
deep scoring. Replace when the edge wear marks have worn at.
Dry Coupled Wheel Probe Maintenance
The dry coupled rubber of the wheel probe is most eective when the contact surface is
slightly tacky. As the Wheel Probe picks up dust and debris from the surface, it becomes
less eective. A cleaning pad removes any dust and debris from the wheel probe and
applies a thin lm of oil to help improve coupling. Silicone oil, such as silicone brake uid,
should be manually applied to the cleaning pad to ensure that it remains moist.
Discoloration of the wheel probe tire suggests they need to be cleaned using a cloth
moistened with acetone. This helps to restore the tire to their original ‘tacky’ condition.
The frequency of cleaning depends upon the condition in which the unit is being used, for
example where the paint surface is particularly dusty (or coated with a thick ‘bloom’), it
may be necessary to clean the tires after each scan.
WARNING!
Only use silicone oil to moisten the cleaning pad. Any other form of mineral oil will damage
the wheel probe tires.
The use of any “oil” other than specied by the manufacturer will invalidate the warranty
on the wheel probe tires.
Wheel Probe Removal
To remove the wheel probe from the probe holder:
1. Disconnect the two Lemo00 connectors at the front of the crawler.
2. Unscrew the two screws of the probe housing lid and lift open.
Figure 6–3 Wheel probe removal
3. Remove the wheel probe from the probe housing. Ensure the wheel probe cables and
Lemo00 connectors feed through the probe holder cover.

Troubleshooting and Maintenance
Cleaning Pad Replacement
The cleaning pad is located within the inner probe sleeve, above the wheel probe. To replace,
1. Remove the wheel probe.
2. Remove the old cleaning pad from the probe housing.
3. Slide in a new cleaning pad.
4. Replace the wheel probe.
Wheel Probe Replacement
To replace the wheel probe into the probe holder:
1. Pass the wheel probe cables and Lemo00 connectors through the guides in the probe
holder cover.
2. Ret the wheel probe into the probe housing. Ensure the markings on the axle face
downwards towards the inspection surface.
3. Close the probe housing lid and secure the two screws.
4. Connect the Lemo00 connectors back to the front of Scorpion2.
Wheel Probe Servicing
The wheel probe can be stripped for cleaning and involves removing the tires and the cork
washer.
Wheel Probe Strip Down
1. Using the circlip pliers, remove both circlips on either side of the wheel probe axle.
2. Remove the side plates then carefully slide each of the wheel probe tires away from
the transducer, over the axles and onto the cables.
Inspection and Cleaning
Inspect the tires for any signs of splitting, cracking, excessive abrasion or any evidence of
swelling due to contact with mineral oil. Check the condition of the cork insulating washer
and ensure that it sits snugly and turns freely in the groove. Check that the ball bearings
in the side plates turn freely.
Use acetone to clean all components and surfaces. Take extra care that all traces of lm
and dirt are removed, especially around the outer circumference and perspex plug over the
crystal and the inner face of the wheel probe tires.
Tire Replacement
If new tires are to be tted, it is very important they are rst cleaned with acetone to
remove the protective lm.
Wheel Probe Re-Assembly
1. Using the syringe, draw up a small amount of silicone oil from the source bottle and
apply a small amount of silicone oil to the inner face of the wheel probe tires.
2. Inspect the cork washer for correct t / damage.
3. Re-t the tires, side plates and circlips. Check for a positive ‘click’ when securing the
circlip, to ensure it is seated correctly in the groove.
