IMPORTANT INFORMATION
1. Verification and Validation – Your guide to Quality Control
1.1 There is a significant difference between barcode verification and
barcode validation – and it is important to understand the difference.
1.2 The only valid method of assessing barcode quality to the correct
standards is to use an ISO/ANSI grade verifier. (A niche area in which
Axicon is the world-leader)
An ISO/ANSI verifier takes about 20,000 measurements of the barcode
and analyses the print quality in order to provide the use with an overall
print quality grade.
This is the method that all major retailers throughout the world (as well
as many other industries) use in order to measure the barcode quality and
to assess whether or not it meets the correct standards - and indeed this
is the only valid test of print quality.
1.3 Because of the amount of data that needs to be accurately collected
and analysed it is simply not possible to achieve this with an on-line
system at production line speeds and so the standards then specify that
an "appropriate statistical sample" of each and every batch should be
made.
And it is then up to the user to determine what is an "appropriate
statistical sample", and the assessment should be based upon the
potential variability of the print quality during the production run. This
can be affected by such factors as the substrate type, print method,
choice of inks etc etc.
1.4 This sampling inevitably means that a few barcodes in the batch will
be measured to the correct standards BUT it also means that if this is the
- 6 -
only test being performed then only a very limited number of products
are actually being tested – other products may have an unreadable
barcode, no barcode at all, or (worse still) the wrong barcode!
1.5 This is where the use of a "validator" comes in - it does not replace
the use of a verifier but instead supplements it.
If the verifier is there to ensure that an "appropriate statistical sample" of
all products are measured to the correct standard then the validation will
provide an additional (not replacement) check to ensure that every single
product has a barcode on it and that all of those barcode were scannable
with the scanner used (and that all barcodes decoded as the same
number).
1.6 Because the validator does not measure quality in the same way as a
barcode verifier it is simply not possible to calibrate this against a verifier
- the two instruments work in entirely different ways.
1.7 The purpose of an on-line Validator is to improve the Process Control
Program by supplementing the off-line ISO/ANSI verifier - it means that
rather than just a small sample of codes being measured as would be the
case using a verifier, that level of checking can now be supplemented by
ensuring that every product has a scannable barcode (i.e. was capable of
being read by this scanner).

2. Axicon Checkrite 5 Barcode Validator – Product Overview
2.1 The Axicon Checkrite 5 Barcode Validator is a mid-performance
validator – it uses the intelligence that is built into the scanner to decode
a barcode and to check whether this is the same decoded number as
previously read.
It can also check whether a successful read was made during a pre-
determined time span.
2.2 If there is a product with an unreadable or a mis-matched barcode
then the validator can be set to illuminate a light display on the front
panel - it also has a spare relay contact available to the user than can be
used to, for example, activate an ejection arm, or trigger the production
line to stop.
2.3 The speed and efficiency with which the Checkrite 5 can detect and
read the barcode is, of course, directly linked to the print quality of the
barcode as well as the scanning distance; we would therefore recommend
the use of an ISO/ANSI grade verifier as part of the set-up of the
Checkrite 5 to achieve optimum performance.

4. OVERVIEW AND OPERATION OF THE SYSTEM
The hub of the system comprises a PLC based control unit with relay to
which a laser bar code reader is attached.
The purpose of the system is to check that the barcodes on the products
are readable and are the correct code.
Before the production run starts it is necessary to “train” the scanner to
recognize the correct decoded number.
This is done by using a “Show-&-Go” method to record the correct
decoded number into the memory of the scanner. The barcode on each
product seen will then be compared to this and action taken if it differs
from it.
- 10 -
4.1 SETTING-UP FOR A PRODUCTION RUN
Immediately prior to a run the system should be set to “train” mode.
This is done by turning the key-switch on the control box momentarily to
the left and holding it there whilst moving the required barcode past the
scanner and then allowing it to return to the central position.
This will cause the barcode to be loaded into the scanner Master Label
memory. It will remain in the memory even after power-off.
Key switch
LEFT: Hold key against spring in “Learn” position whilst scanner is scanning the barcode. Amber light will illuminate to indicate that a “learn” process is taking place. This is then used as the “Master Label”. Key is retained
CENTRE: Normal operating position Key removable
RIGHT: Reset System OVERIDE if left in this position Key removable
- 11 -
4.2 DURING THE PRODUCTION RUN
4.2.1 As a bar coded item passes the sensor it breaks the reflected beam
which causes the scanner to be automatically triggered and the laser is
switched on for the pre-configured timeout period.
4.2.2 If a new trigger is received (item passing the sensor) before the
timeout has expired the previous read-cycle will end immediately and a
new cycle started.
4.2.3 The output from the scanner is then fed into the PLC in the control
box which interprets them and illuminates the lamps appropriately:
A. If the code is successfully decoded and is the same as the Master
Label, the Green Lamp will illuminate. GOOD READ.
B. If the code does not read because it is unreadable, misapplied or
not present, the Amber Lamp will illuminate. NO READ.
5 consecutive No Reads (default setting) will cause a machine stop with
both Amber and Red Lamps illuminated.
(Note: The number of consecutive no-reads before both amber and red
beacons are illuminated can be modified in the PLC settings and this
should ideally be done at the time of manufacture)
C. If the code is not the same as the Master Label the Red Lamp will
illuminate. MISMATCH. The machine stop will operate*
*Machine Stop :- There is an extra relay output available for connection
to a line stop input. This is a volt-free relay contact (which can carry a
24VDC or 110-240VAC signal) and is configured with both normally-closed
and normally-open contacts on the connector.
- 12 -
At the end of a Good Read or a No Read cycle the relevant lamp will
remain illuminated until the next trigger. This means that the result of
the previous cycle is always visible. A new trigger switches the lamps off
and a new cycle begins.
5 consecutive No Reads (No Read counter) will cause a machine stop
with both Amber and Red lamps illuminated and latched.
A Good Read or a manual Reset from the key-switch will reset the
No Read counter.
The Master Label is always remembered for power-down and will
not need to be reloaded at the start of every batch.
Once the machine Stop has operated it can only be reset by turning
the front panel switch to the right. The switch can be left in this position
and the key removed. Under this condition the system is disabled so this
must be at the discretion of an authorised operator. It is strongly
suggested that they key is not left in the unit during production runs.

5.0 INSTALLING THE SYSTEM
WARNING
The Checkrite 5 Validator requires a mains voltage power supply
(100 – 240v) with the consequent risk of injury.
The Validator should only be installed by suitably qualified personnel.
After installation the key to the front door should be removed and
retained in a safe place away from the validator. (Operators should
not need to open the front door for any reason whatsoever).
Neither Axicon Auto ID Ltd nor the vendor of the validator can accept
any liability arising from the incorrect installation or operation of this
equipment.
- 14 -
The following description assumes that the control unit is suitably
mounted and the stop signal is connected to the machine stop input.
5.1. Mounting the scanner.
5.1.1. Positioning the scanner:-
Guidance Recommendations as to the optimum distance from the scanner to the barcode:- Code Media/Print Magnification % Scan Distance (mm) EAN13 Thermal label 150% 100% 100mm EAN13 Litho on white 100% 100% 100mm GS1 128 Thermal label 60% 100% 220mm ITF14 Thermal label 60% 100% 220mm ITF14 Ink-jet 75% 75% 220mm ITF14 Flexo on white board 100% 100% 220mm ITF14 Flexo brown code on white board 100% 75% 220mm ITF14 Thermal label on green 80% 70% 200mm ITF14 Thermal label on pink 80% 100% 200mm ITF14 Thermal label 80% 100% 200mm ITF14 Flexo on brown board 65% 90% 200mm ITF14 Flexo on brown board 100% 95% 220mm
(These are based upon tests performed by Axicon and may need to be
adjusted for other substrates or codes.

5.1.2 Mounting the Scanner
IMPORTANT:- When mounting the scanner to a bracket screws of M4 x
6mm should be used.
If screws are used which are too long these may damage the scanner.
Mount the scanner at an angle of approximately 10 between the laser
beam and the barcode. This is recommended to avoid specular reflections
from the surface of the code.
Note:- if this is not done then the read rate of the barcode will be
significantly reduced.
Troubleshooting:-
If, having mounted the scanner at the recommended distance and tilt
angle the barcode read-rate is poor, we would recommend that samples
of the barcode be checked off line by an ISO/ANSI verifier to assess print
quality as the most likely cause of the problem is a badly printed
barcode.
Corrective action should then be applied as necessary.
Tests have shown that poor quality barcodes significantly reduce the read
rate of a scanner and also make it mush more sensitive to having the
correct scanner/barcode distance.

5.2 Mounting the Control Box
Preferred option:
The user may purchase the optional “Mounting cradle” in which case
they would fit the cradle to the wall/machine and then “drop” the
validator into the cradle, connect it up and it is ready to go.
Alternative option:-
The control box may be mounted direct to the wall/machine without
the use of a cradle, using the mounting positions as shown in the
diagram below.
(Please note that this would involve opening up the validator in order
to mount the control box.)
Care must be taken by the installer to ensure that no components
inside the validator are damaged during this fitting process, also that
ingress of dust etc is avoided.

5.3 Installing the trigger sensor/setting time-out period
The trigger sensor must be mounted such that it should start the scanning
process just before the bar code moves in front of the scanner and after
the previous barcode has cleared the scanning path.
As standard the Checkrite 5 is supplied with a broken beam sensor
comprising the sensor which is positioned at one side of the production
line and the reflector at the other. When the reflective beam is broken
then the read-cycle begins.
The scanner will have a pre-set time-out period.
The time-out period must be sufficiently long to ensure that the barcode
has completely moved past the scanner before it expires (and
automatically switches off). The amount of time required depends upon
the line speed, position of the barcode on the box etc.
Axicon also offer both short range and long range sensors for special
applications, however the broken beam-sensor is supplied as standard
since this gives consistently the best performance and is the most
reliable.

5.4. Machine Stop output
The connector panel on the underside of the Checkrite 5 looks like this:-
You will see the
“Machine Stop”
connector at
the left hand
side.
The connector contacts are shown here:-
This allows the user to select the
appropriate contacts to meet either a
“normally open” or “normally closed”
requirement
5.5 Maintenance
Once installed the scanner window should be cleaned of any dirt.
Please note that the recommended method is to apply a small quantity of
commercial glass cleaner to a soft lint-free cloth and wipe the window
with this.
Do not soak the scanner with liquid cleaner and do not rub excessively –
as either will adversely affect the operation of the system and could
permanently damage the scanner.
The window should be kept clean for best performance and this should
form part of a regular maintenance routine.

8.0 Checkrite 5 - Quick Start Guide
1. On power-up turn Key 45º to right (“RESET”) to clear all indicators
then return to centre for operation.
2. Load new product or packaging onto the line
3. Turn Key 45º to left (“LEARN”). HOLD in this position whilst
scanning the required “master” barcode – the amber lamp will be
illuminated to indicate a successful “learn”. The user should then allow
the key to spring back.
The key should be removed at this time to prevent the code being
overwritten.
4. Start the line
5. Green lamp = Good,
Amber = NoRead (5 in a row will stop the line with Amber & Red
on).
Red (only) = Mismatch (Stops the line immediately).
6. Red and Amber lamps on = 5 consecutive no-reads which has
triggered a line-stop
7. After a Line Stop remove all incorrect packaging, turn Key 45º to
right (“RESET”) and return to centre; it’s now ready to start again.
7.a) NOTE: System will remember the Master Code on Power-off – there
is no need to re-enter it.
Last Code GOOD
Last Cycle NOREAD
Last Code WRONG CODE (RESET Switch to restart) Note - The Key can be removed while in RESET position – this provides a System
Override which can be useful where a pack design does not include a barcode.
