INTRODUCTION
The SCANMAX 25 is a fluoroscopic X-ray cabinet specifically designed for the detection of explosive
devices, hate mail and other contraband material concealed in incoming mail and packages. Items are
placed in the inspection chamber and simply by pressing a push button switch a high resolution image is
displayed on the video monitor. Image reversal, high penetration and 2 different colour palettes are
available. These and the zoom facility will expedite the recognition of the items in the package.
It is ideally suited for use in government and commercial mailrooms, embassies, prisons and courtrooms. It
can also be used in reception areas for the inspection of briefcases and hand-delivered items not passing
through the central mailroom.
The SCANMAX 25 is completely self contained and can be put into operation immediately and can
examine the contents of a parcel 40 x 50 cm (16” x 20”).
A parcel, briefcase or a batch of
envelopes/small packets can be examined in less than 10 seconds.
The SCANMAX is designed to ensure operator protection against radiation hazards through the use of lead
shielding. An interlock system on the door prevents the generation of X-rays when the inspection chamber
door is opened, ensuring maximum protection to personnel. Even so, always be aware that radiation (Xrays) can constitute a distinct hazard if not employed in strict accordance with the instructions provided in
this manual.
Before operating the SCANMAX 25 all personnel designated to operate the unit, or supervise its operation,
must have a full understanding of the contents of this manual.
UNPACKING INSTRUCTIONS
The installation of the SCANMAX 25 is relatively simple and requires no special tools. It is shipped as a
whole in a sturdy ply wood container mounted on a wooden pallet. The shipping crate is designed to
withstand normal handling during overseas shipments.
Despite these safeguards, damage may occur in transit. Therefore, immediately inspect the exterior of the
container for evidence of damage. In the event damage has occurred, immediately notify the carrier at your
location.
UNPACKING THE SCANMAX 25
To remove the SCANMAX from the shipping crate, perform the following:
1.
Undo the binding and open the box with the help of a large screwdriver.
2.
Using extreme care, remove the pallet and lift the equipment into place. For this use a lifting trolley
or fork-lift truck. Care must be taken to avoid scratching the unit.
3.
Inspect the SCANMAX cabinet for evidence of any physical damage.
WARNING:
Physical damage to the SCANMAX cabinet may result in excessive radiation emission
levels. Any damage observed should be thoroughly investigated, prior to operating
the unit and must not be used until authorised.
Fitting of Handles
Handles have been provided for the location of the units at the time of installation, when they require to be
dismounted from their wheeled base or for relocation of the unit.
The handles are universal in that they are designed to fit any of the range of Scanmax units. The outer holes
are for the Scanmax 20 the centre for the Scanmax 25 and the inner holes for the Scanmax 15.
Screws have been provided at the front and rear of the unit to fit the handles.
The only tool required is a screwdriver with a narrow shaft with the head of the screwdriver small enough
to fit through the holes on the handle.
Simply remove the screws from the unit and with the open side of the handle uppermost place the screw in
through the top and through the rear hole. Line up the screw with the unit and tighten.
When the unit is positioned remove the handles and replace the screws into the unit. Do not operate the unit
with the handles fitted. Do not attempt to open the door on the Scanmax 20 with the rear handle fitted.
WARNING
When lifting the unit extreme care must be taken as the units are top heavy.
It is strongly recommended that four people are used to lift the units one at
the end of each handle.
IMPORTANT:
INSTALLATION ADVICE WHEN USING A SUPPORT TROLLEY
TO FIT THE TOP UNIT TO THE BASE THE FOLLOWING PROCEDURE MUST BE USED
1.
Ensure that the feet have been removed from the base of the Scanmax before attempting to place
the unit on its trolley.
2.
The unit can be placed on the trolley in either direction.
3.
Assemble the unit at, or close to, the intended site of operation as the Scanmax 25 is top heavy
when on its base. Care must be taken whilst moving the unit on its base.
4.
Fit the feet up through the trolley to secure the unit. This ensures that the feet are available for use
if the unit is to be operated dismounted and also will ensure that unwanted light does not enter the
cabinet through these holes.
PRE INSTALLATION GUIDE
WARNING:
To ensure operator safety, radiation emission levels must be checked before putting
the SCANMAX into operation (See page 20)
Prior to first time operation, it is essential for the safety of the operator and for the long life of the
equipment that the following instructions are strictly observed.
Ensure that the system voltage is the same as the mains supply voltage available. If in doubt regarding the
mains voltage at hand, perform a measurement. Units will be set at 230V unless otherwise instructed and
should therefore only be operated from a 230V mains supply. Connecting to a different mains voltage will
result in improper operation or even destruction of the unit.
Ensure that a good mains earth is provided. To minimise shock hazard the SCANMAX must be
connected to an electrical ground or earth. The unit is equipped with a three conductor AC mains lead.
The corresponding socket at the installation must be fitted with a reliable protective earth contact.
SCANNA or the supplier cannot be held responsible for incorrect connection.
Do not operate the equipment in the presence of flammable gases or fumes.
protective devices (fuses etc.).
INSTALLATION GUIDE
1.
Take unit out of box (following the instructions in the previous section) and place on a
strong table/base, or the trolley if provided, capable of supporting up to 200 kgs. Take
extreme care when lifting as the unit is very heavy (160 kgs/352 lbs). Use a lifting trolley
or fork lift truck. Ensure that there is unrestricted access to the inspection chamber door.
Ensure that the door is fully closed.
2.
Connect monitor to unit by means of the ‘D’ connector and power cables supplied
3.
Connect the trackball and place on a suitable surface. (Can be hand held during operation)
4.
Plug unit into the mains supply after checking voltage of machine matches local voltage
5.
Ensure that the door is fully closed and insert the key into the key switch on the front
control panel and turn it clockwise to switch on the unit. The green SYSTEM READY
light should illuminate to indicate the interlocks have been operated and that the equipment
is ready for use.
6
Perform interlock check by doing the following:
Activate the red X-RAY ON button on the front control panel. Observe that all X-ray
lights illuminate and that they remain illuminated. Slowly open the loading door and verify
that the X-RAY ON and warning indicators switch off as soon as the door is opened.
7.
Check image quality by placing a sample package into the centre of the inspection cabinet.
8.
Using the Trackball check that the left hand switch rotates through the zoom function and
that the right hand switch rotates through the six image formats.
IMPORTANT
Upon installation and after any relocation a critical examination report should be carried by qualified staff
with the appropriate radiation survey equipment using copy of the report found on page 23 for record
purposes.
If all controls function properly and the radiation tests show the equipment to be safe then the SCANMAX
is ready for operation
WARNING
THIS EQUIPMENT PRODUCES IONISING RADIATION WHEN ENERGISED AND SHOULD BE
OPERATED ONLY BY TRAINED PERSONNEL
IMPORTANT SAFETY PRECAUTIONS
The SCANMAX 25 utilises an X-ray generator that is lead shielded against radiation emissions. The
generation of X-rays stops automatically as soon as the door is opened, accidentally or otherwise. This
high level of safety conforms to the strictest protective measures against radiation.
The SCANMAX 25 is inspected, and the results documented, prior to shipment to ensure that radiation
emission levels are well within the legal requirements.
Modification
No modification of the SCANMAX, particularly the radiation chamber, should be
attempted without written consent from the manufacturer.
Support
If the SCANMAX is moved after initial operation, extreme care should be taken to
ensure proper handling. Use mechanical aids such as forklifts or lifting jacks. Do
not place the unit on an inadequate support or try to lift it unaided. If the unit
is dropped, do not attempt to resume operation before consulting a qualified
service technician. The user must be aware that excessive radiation leakage could
develop due to mishandling.
Relocation
A radiation leakage survey, conducted by highly qualified personnel, must be
conducted and documented (see page 23) after any relocation of this equipment or
after any modification to the equipment. This procedure will prevent radiation
health hazards to operating personnel.
Grounding
To avoid electrical shock, ensure that the grounding is not defeated.
Wiring
All abnormal use or modification of the internal wiring is unacceptable. Scanna
cannot be responsible for any damage or injury caused by such action
Health & Safety
UK radiation control regulations require the registration of radiation Sources with
the local Health and Safety Executive. Registration should be made within 30
days of purchase. Contact your local HSE for further information.

INTRODUCTION TO X-RAYS
Radiation and the inherent dangers of radiation have in recent years received much publicity however since
1972 the use of x-ray systems has become commonplace throughout the world particularly at Airports.
Indeed in these troubled times the public and staff demand the level of security provided by these x-ray
screening systems.
The use of x-rays is no more dangerous than a piece of industrial machinery with moving parts, if you put
your hand in moving machinery, such as a guillotine, you may be seriously injured, fortunately this type of
accident is rare, if common sense and safety procedures are implemented.
The same is true with an x-ray unit. Not interfering with guarding or access panels, NEVER defeating
interlocks and regularly servicing the equipment will provide a high degree of safety.
Contrary to Radioactive Sources the x-rays or Ionising Radiation used in the Scanmax 20 and other
systems supplied by Scanna are non residual. That is the x-rays are produced electrically and as soon as
the power is removed from the x-ray generator there are no x-rays in the system.
The following safety measures and devices are included in the equipment supplied by Scanna MSC.
Low x-ray dose.
X-ray beam limiting.
Interlock system.
X-ray On indicators.
Lead Shielding
In the United Kingdom the requirement is a leakage rate as low as is practicable but in no case to exceed 1
micro Sievert per hour. It is the stated intention of Scanna to provide equipment designed so that irradiation
leakage is zero. The Regulations and the Code of Practice has introduced conditions whereby doses of
radiation can and are maintained considerably below the threshold where the radiation has an detrimental
effect. Indeed it is accepted that by far the largest contribution to population dose is from our natural
background, e.g. radiation from space (300 µ Sv), Gamma radiation from earth (350 µ Sv ), internal
radiation from natural radioneuclides in the body.(380 µ Sv ) and inhaled gases and nuclear fallout (970 µ
Sv). The current safety limit for annual exposure is 5000 µ Sv

It can be seen from the above figures that spending every hour of your working life within 1 inch of the
equipment with the x-rays switched on would still not so much as double your annual dose of radiation
accrued simply from being alive.
OPERATING INSTRUCTIONS
1.
Switch on mains isolating switch on the rear panel. Note that the front panel “POWER ON “
indicator on the front control panel illuminates.
2.
Insert the key into the key switch and turn a quarter turn to the right ensure that the TV
monitor is turned on.
3.
Place objects to be inspected inside the chamber and close the door firmly (take care not to
slam the door). This enables the radiation safety interlocks and the SYSTEM READY light
will illuminate.
4.
Depress the ‘’X-RAY ON’’ switch and release. The ‘’X-RAY ON’’ indicators will illuminate
for 5 seconds.
5.
After 5 seconds an X-ray image of the item will become visible on the monitor screen, adjust
the Brightness and Contrast controls on the monitor to obtain the optimum image on the
screen.
6.
Security Screening can be accomplished quickly and can normally be completed within 5-10
seconds. This is usually sufficient to determine whether a package is harmless or contains a
suspect article however the image is displayed for as long as required
7.
Closer examination can be made by use of the trackball. When the ball is moved a square is
illuminated on the screen, move the square centrally over the area for closer examination and
press the left hand key and the image will be enlarged by a factor of 2 (Zoom x 2 ) If a further
close look is required press the left hand key again for x4 or x8 and then press again for
Normal image. The image will revert to Normal image when a new image is obtained by
pressing the X-ray On switch.
8.
The right hand key of the trackball will give the following image displays:
1
2
3
3
Normal display.
Brightened “high penetration” grey.
“Inverse” (negative ) grey level image
Green / Orange / Grey
“Organics” mode
dense objects show as green, less dense
objects (plastics and narcotics may show as
orange). Other regions show as grey scale
5
Red/Grey “Bomb” mode Very dense objects show as red other regions as grey
scale.
6
Red / Green / Yellow
A “vivid” bright colour display to emphasise
colour capability.
Access is gained to each enhancement by repeatedly pressing the right hand trackball key
until the image required is displayed, repeated pressing will return to the Normal image.
When a new image is obtained the last enhancement used will be the display mode used for
the new image.
9.
Normal letters, express mail etc., can be inspected in batches of 25 or more at a time. This
will expedite the screening process. It also reduces the use of the system. Larger packages or
briefcases should be inspected individually. (See next section for more details).
10.
The SCANMAX 25 should be turned off when not in use and the key removed from the
equipment. The key should be kept by a designated key-holder/supervisor
11.
Operator maintenance involves only the cleanliness of the unit both inside the inspection
chamber and the outside of the unit and regular safety checks to include mains lead etc.
Hints:
•
Tilt or change the orientation of an object to obtain a clearer profile.
•
If photographing, use shutter setting 30 or 60 to allow for the camera to synchronise to the monitor
(Lines will appear across the film if it not synchronised) to ensure good depth of field, black and
white film will tend to give higher apparent contrast.
•
If used for law enforcement or security, obtain appropriate training from a qualified person.
Warning:
If the indicators start flashing on and off a fault condition has occurred. One of the indicators will have
failed, when the indicator has been replaced the unit should be switched off at the mains supply on the rear
of the unit and then switch on again. If an X-ray warning indicator flashes the unit will not be able to
generate x-rays until the fault condition has been corrected.
X-RAY SCREENING PROCEDURES
1.
Envelopes may be processed in batches, or evenly spread out within the inspection chamber.
2.
Larger packages or briefcases should be placed towards the centre of the unit and processed flat
and one at a time.
3.
Any item screened which shows the presence of anything unusual (i.e., wires, electrical switches,
batteries etc), or which contains high density (black) materials which cannot be penetrated should
be treated with extreme caution.
4.
If the item appears suspicious, security staff should be alerted and the appropriate security
procedures implemented.
SCANNA strongly recommend that users of X-ray inspection equipment implement proper security
procedures for dealing with suspect packages.
SCANNA also recommend that operators have appropriate training in the recognition of suspect
packages and X-ray image identification. Contact SCANNA or your local Police/Law Enforcement
Agency for advice on suitable courses.
Be sure to display contacts and appropriate emergency telephone numbers adjacent to the unit.
MAINTENANCE
The SCANMAX 25 contains no user serviceable parts other than lamps and fuses. For reasons of safety
maintenance of the unit should be undertaken by a trained engineer at least once a year during which the
security, integrity and levels of all components should be checked. A radiation leakage check should be
carried out using a calibrated radiation level monitor. Please contact your service representative or
SCANNA MSC. for most maintenance needs. A few common procedures are described below and all
should be referred to your service representative.
Refer any further problems to SCANNA MSC. Procedures listed in this section include:
Line grounding and regulation
Fuse replacement
X-ray source replacement
Door Adjustment
Camera adjustment and cleaning
Testing for radiation leakage
SCANNA MSC does not accept any liability for damages resulting from system modifications
performed by the customer.
Line Grounding and Regulation
Regulation
When the unit is energised, the line voltage should drop no more than 5% at the wall outlet. Any further
drop indicates that your AC power source needs to be upgraded.
Grounding
A three pin plug must be used with a suitable earth or frame ground. If this ground is not at actual earth
potential a shock hazard can exist. For this reason it should be checked and if possible, outlets with ground
fault interruption should be used.
Warning
Always disconnect the power cable when working on the tube head or controller. Line voltage can be
present at the controller when the key switch is not activated.
Fuse Replacement
Below the mains input socket for the power cord at the rear of the unit is a fuse holder. It is covered by a
rectangular piece of black plastic which is part of the holder. Pull outward on this holder until the fuse is
exposed. Replace with a 15 amp, 230V, 2 AG style Slow Blow fuse. An extra location is provided where
a spare fuse can be kept if needed. If the fuse blows repeatedly, call your service representative.
X-ray Generator and Controller Replacement – Trained Service Personnel Only
In the event of failure of either the Generator or the controller the Serial number of both the unit and
the faulty x-ray generator must be given to SCANNA to ensure that the correct replacement will be
supplied.
The Primary voltage and the tube current are pre-set in the controller software, and it insures that
factory pre-sets have been observed. Contact SCANNA if alternate arrangements need to be made.
To replace the x-ray generator and controls follow the procedure below. Read safety precautions
listed elsewhere in this manual before proceeding.
S1.
Warning: disconnect the power. Remove the cover at the top of the unit..
Disengage the wiring connections carefully from the x-ray source.
S2.
Loosen the x-ray generator by unfastening the four screws holding it in place.
S3.
Disconnect the in-line plug / socket to the x-ray source.
S4.
Remove the x-ray generator from the case.
Caution :The x-ray generator is heavy two persons are required for this task.
S5.
Pack the x-ray generator in a shock resistant shipping carton so that the ceramic and glass parts of
the system do not become damaged. Note, any compression or shock to the outside of the tube
head container is transferred directly to the glass envelope of the X-ray tube!
To install a new x-ray generator, repeat the process but in reverse.
S1.
Install the new x-ray generator and bolt down.
S2.
Reattach the connections to the x-ray generator.
S3.
Refit the top panel ensuring the earth lead is re-connected
Controller Removal
S1.
Ensure that the unit is disconnected from the mains supply.
S2.
Open the rear connection panel (Eight screws).
NOTE: The Controller is isolated via a panel interlock switch by this action.
S3.
Note the position of the connections and disconnect.
S4.
Remove the Controller by removing the four mounting nuts taking care not to misplace the
nuts or the insulators.
Fit the new Controller in reverse order
S1.
Fit the Controller module.
S2.
Refit the connectors to the Controller module.
S3.
Refit the rear connection panel and test the unit. Check the panel interlock for correct
operation
Door Adjustment:
This must be carried out by service representative
To re-seat the door in case of mechanical trauma or accidental loosening of screws, use the following
procedure:
S1.
Loosen screws on right side of door and back out the set screws until flush with the
hinge.
S2.
Lift the door and secure the screws. This should eliminate radiation leakage at the door. Be sure
that the plunger interlock on the door is not damaged.
S3.
Re-tighten screws to fix position. Tighten set screws to ensure that setting does not change. Set
screws can also be used to provide a very slight adjustment from left to right if
needed.
S4.
Test for radiation leakage and correct as needed. You must reject the unit at this point if levels
of 1µSv/hr are exceeded.
Final re-seating of the door should be performed in conjunction with radiation testing to ensure that proper
fit has been achieved. Door fit was correct upon shipping of the unit from the factory if proper installation
instructions have been followed.
The attached Maintenance Report Sheet should be completed by the engineer carrying out the maintenance.
Camera Adjustment and Cleaning
Disconnect the unit from the mains supply.
If carrying out adjustments in the bottom of the unit to the camera and its lens whilst the unit is energised
be sure to keep all parts of the body and metallic tools clear of the Isolating transformer and any wiring.
The camera is accessed by removing the front control box.
Three screws on the base of the control box are removed and the box carefully lifted taking care not to put
tension on the connections to the control panel.
The camera lens may after a period of time become dusty. It is recommended that any loose dust on the lens
should be initially orally blown off and then clean the lens using a proprietary lens or spectacle cleaning
cloth ensuring that the lens is not scratched.
The lens is normally kept with the aperture wide open (f1.6). If the unit is to be checked with the rear panel
open, close the lens until the image on the screen is suitable (Remember to return to f1.6 before replacing
the side panel) The camera / lens can be focused on its own image reflected from the lead glass in the base
of the inspection chamber.
Re-fit the access panel after adjustments ensuring that the earth straps are re-fitted to the panel.
Testing for Radiation Leakage
To complete an accurate radiation leakage test, follow the detailed instructions on the enclosed radiation
leakage form see page 24.
WARNING:
This can only be accepted when performed by a qualified technician using an approved radiation
meter.

CCD CAMERA
The VC21 camera has been specifically modified for use with the Scanmax 25 camera system and
care must be taken when handling the camera and the lens mountings to ensure that connection of
the multi way connector is not damaged or broken.
PRECAUTIONS
• Do not aim the camera towards the sun or extremely bright object.
• Do not touch the CCD imager it is very sensitive and not user serviceable.
• Do not attempt to disassemble the camera unnecessarily. There are no user serviceable components
inside.
FEATURES
High sensitivity in a low light level down to 0.02 lux for excellent picture quality.
Picture burn in does not occur
Excellent immunity to vibration and shock.
The camera interface uses solid state components and requires no periodical maintenance work or
replacement of components during normal use.
ADJUSTMENTS
The only adjustment available is the lens aperture and focus.
A live image display mode is provided to allow for easy installation of the camera. In this mode the
camera operates as a standard camera, displaying a live image on the monitor. This mode is used for
setting the camera into its correct position and setting the focus. Live display can be activated by
switching the set-up line and will stay in that mode until the x-rays are energised when the camera
automatically reverts to normal operation.
