INTRODUCTIONINTRODUCTION
INTRODUCTION
Congratulations for choosing a BTSR product.
With our SMART 3000TW yarn control system, you get an innovative, unique
solution, able to offer you multiple advantages concerning quality control of your
production.
SMART 3000TW has been designed for applications on large warping machines
that use in continuous mode a large number of yarns (up to 1920) during the entire
working cycle.
The system is able to self-learn the yarn sequence picked-up by the textile machine
during a sample cycle and to indicate any type of error detected during the
subsequent production cycles (broken or missing yarns, uncut or wrong sliding
yarns, wrong threading or wrong picking-up errors, etc.).
This allows to eliminate up to 80% of waste and seconds quality that would
normally occur during production; in addition it dramatically reduces needle
breakages and machine stops, thus allowing a rapid pay-back of your investment.
SMART 3000TW, combined with IS3.. yarn smart control sensors, represents a
full and effective machine control system.
How to use this Manual
This Operating Manual is divided into 4 Chapters and 1 Appendix.
Chapter 1 – Overview describes the main features, components and how the
system works.
Chapter 2 – Technical Data and Installation gives the necessary instructions to
install the system correctly.
Chapter 3 – Operation gives a detailed description of the necessary operations to
setup and program the system according to the application needs.
Chapter 4 – Troubleshooting and Maintenance provides a quick guide to solve
the main technical faults of the system.

1 - OVERVIEW
System Components
The SMART 3000TW system includes a control/programming terminal and a
variable number of IS3.. type sensors connected to the terminal by means of 1 to 8
SMART 200 INT-TW 485 Interface Boards.
Each Interface Board can handle up to 240 IS3.. Sensors. The maximum number of
sensors the system may handle is therefore (8 x 240) = 1920.
System’s Operating Principles
The sensors’ detection features (Start Frequency !F_START, Stop Frequency !
F_STOP, Sensitivity !SENS, Reaction Time !DELAY)can be programmed
according to the type of yarn being processed.
These features must be programmed on each sensor and can be changed according
to the application.
The terminal has in fact the function of programming and, changing (if needed) the
sensors’ features, according to the production requirements.
The main task of SMART 3000TW is to provide a continuous production
monitoring and an automatic computation of the yarns used (CONTROL function),
by comparing each production cycle with a sample cycle previously self-learnt
(LEARN function) under “ideal” conditions, thus detecting possible deviations with
respect to the above mentioned sample cycle and stopping the textile machine
when the detected errors exceed the set tolerance.
Special Features of SMART 3000TW System
The SMART 3000TW system has a set of unique features which make it a true
microcomputer dedicated to programming/control of production and statistical
analysis of technical faults.
During the production monitoring phase the system stores all the technical faults
each sensor founds, allowing the machine operator to analyse which and how many
technical faults have been detected by each individual sensor.
The main advantages of this solution can be summarised as follows:
!Absolute flexibility:
thanks to the possibility to quickly change the sensors’ program, according to
the application.
!Maximum simplicity:
concerning the installation as well as programming and administration of the
system.
!Maximum precision:
the possibility of programming the technical features of sensors according to the
type of yarn to be processed, guarantees a perfect symbiosis between sensor and
yarn.

The system automatically learns the sequence of yarns used by the textile
machine.
!IS3.. Sensors (Image Smart Scanning Sensor) (BTSR Patents)
The sensors of the IS3.. series are connected to the SMART control terminal by
means of simple multi-connector cables, thus making quite easy the system
installation task.
!Automatically assigned numbers (BTSR Patents)
The identification of sensors is performed by the system by means of an
automatic numbering procedure resulting in a simple and fast system
configuration.
!Programmable Functions
The systems allows programming the sensor detection features (Sensor Image
Variation Frequency, Sensitivity, Reaction Time, Tolerance, etc.).
!Production Data
The system records, during production, the machine stops detected by each
sensor and by error type.
!Easy Monitoring
Besides the information provided on the graphical display of SMART 3000TW
terminal, each IS3.. series sensor has a red LED that, when flashing, indicates
the location of the yarn technical fault, making the operator intervention easier.

SMART 3000TW Terminal Features
As in all SMART BTSR systems,the operation of SMART 3000TW system is
controlled by just 5 membrane buttons and it is monitored by a LCD graphic
display, which guides the operator through all programming and administration
phases of the system, by means of straight-forward messages which can be
understood clearly and immediately.
On the top left side of each button there is a red LED, which indicates particular
conditions.
The display screen includes two separate zones used respectively for displaying
messages to the operator !during the system programming and administration
phases and for signalling the operating status and levels in which the system is
working ".
The following picture shows the location of the buttons and display zones that
constitute the control panel of the system.
1. ENTER button
Pressing and holding for 3 seconds the ENTER button when the system is in
control condition (CONTROL nnnn displayed), gives access to P1 programming
level.
Pressing and holding for 3 seconds the ENTER button while the system is at
beginning of P1 menu (**P1** displayed), gives access to PX programming level.
When the system is running any of the programming menus, pressing the ENTER
button confirms the current parameter and selects the next parameter within the
current menu. When pressed on the last item of the menu, causes the return to the
beginning of the same menu (cyclic function).
2. RESET button
When the system is running any of the programming menus, pressing the RESET
button causes the return to the beginning of the same menu; pressing it again
causes the return to control condition (CONTROL nnnn displayed).

Operating
- 3.2 - SMART 3000TW
3. NEXT CY button
During the parameters setting phase, within a programming menu, it allows you to
increase the numeric value of current filed. If it is kept continuously pressed, the
numeric field increases more quickly.
When the system is in control condition (CONTROL nnnn displayed and red Led
on, inside the CONTROL button), pressing the NEXT CY button activates the
NEXT CYCLE function:
-The system is disabled for a complete control cycle
-The red Led inside CONTROL button turns OFF
-The red Led inside NEXT CY button turns ON.
When alphanumeric data are entered (for instance the Key_cod or K_learn), this
button allows the increase of characters pointed by the cursor, according to the
following cyclic sequence:
4. CONTROL button
During the programming phases requiring the entry of 2 or more parameters within
the same screen shot, pressing the CONTROL button switches from the current
parameter (indicated by blinking cursor), to the next parameter (cyclic function).
5. REPEAT button
During the parameters setting phase, within a programming menu, it allows you to
decrease the numeric value of current field. If it is kept continuously pressed, the
numeric field decreases more quickly.
When alphanumeric data are entered (for instance the Key_cod or K_learn), this
button allows the decrease of characters pointed by the cursor, according to the
following cyclic sequence:
Meaning of Red Leds inside the SMART 3000TW Terminal
During normal operation, the SMART 3000TW terminal signals the current
working condition through the status of Leds embedded in the five function
buttons. The meaning of Leds is the following:
ENTER LED If switches on and off alternatively, each time the system
receives a synchronism signal (PRX).
NEXT CYCLE LED It switches on when the NEXT CYCLE function is activated
(next cycle).
CONTROL LED It is On when the system runs the Control phase.
It is Off when the system runs the Learn phase.
REPEAT LED It switches on when the RESET signal is active (ON).
RESET LED It is On when the machine is stationary.
It is Off when the machine is running.

SMART 3000TW - 3.3 -
6. Operator’s message Area:
The menu choices, or settings for the selected function during programming or
setup phase of the system as well as service messages are displayed here with large
size fonts (1,5 x 0,8 cm), easy to read even from a distance, when the system is
running normally. In other words, this area shows all the necessary information to
guide the operator step by step through the programming phase and interactive
management of the system.
The presence of a flashing cursor (---) indicates the position where the operator
can enter a numeric value or variable setting which will replace the value currently
displayed.
7. Operating Status Signalling Area
To enable a more direct and evident interpretation of the operating context in
which you are working, on the right hand side and bottom side of the operator
message area, 16 rectangular boxes (labels) are implemented. They display the
operating status of the system, and the hierarchic level of the menu at which you
are operating.
More specifically, the PROGRAM label indicates that you are operating in one of
the following modes: configuration, programming or data transmission to the
sensors. The CONTROL label indicates that the system is operating normally with
all monitor functions enabled, and according to the settings currently set in the
system. In this phase the message display indicates CONTROL nnnn. The
ERROR label indicates that an error has been detected during normal operation of
the system. In this case the message display shows the type of error detected (for
further information please refer to Operating Sequences).
The labels P1 .. P5 indicate the hierarchic level of the menu in which you are
operating.
The WAIT label indicates that the button you are pressing has a timed function, for
instance if you press ENTER while the system is in Control condition, the WAIT
label indicates that, if you keep the button pressed for 3 seconds you will access the
P1 menu.

SMART 200 INT-TW 485 Interface Board Features
The Interface Boards work basically like the SMART
3000TW Terminal, i.e. they act as Slave CPUs with respect
to the Terminal (master CPU) and, in turn, they control the
connected IS3.. Sensors, using a microprocessor and a
software similar to those of master terminal.
The main difference is that all programming / setup
functions of the entire system can only be carried out on
master terminal, while the communication functions
towards the sensor are individually carried out by each
Interface Board.
The Interface Board status is signalled by 8 red LEDs, which light to indicate respectively:
Board in STOP/ALARM condition (Error message displayed on terminal screen).
Next Cycle function active, i.e. NEXT CY and RESET push button pressed on main
terminal. (The system remains disabled for an entire control cycle, during which the
CONTROL LED stays off both on Boards and on main terminal).
RS485 communication port inactive.
System running in Control mode (CONTROL nnnn displayed and Red LED of
Control button On).
System running in Learn mode (LEARN nnnn displayed and Red LED of Control
button Off).
Board running the automatic sensor numbering function (once all the sensors
connected to the Board have been numbered, this LED turn off).

IS3.. Sensor Features
The IS3.. electronic sensors are capable of detecting, thanks to a patented and
advanced control technology, the image variation of a moving yarn under control;
it can show with absolute certainty the actual movement or stop condition of the
yarn. The technique based on image variation makes the IS3.. sensor exempt from
the influence of environment/yarn conditions: i.e. humidity, conductivity and
machine vibrations. It does not require any physical contact with the yarn under
control and therefore allows perfect monitoring without affecting the tension
features of the yarn itself in any way. The IS3.. devices are the most reliable and
advanced solution for yarn control in textile machines. IS3.. is an unique electronic
sensor for yarn control; when combined with the SMART series controllers, thanks
to a patented innovating technique (Image Smart Scanning Sensor), it does not
require complex cabling and long installation time; the new multi-connector cable
allows in fact to control multiple sensors. IS3.. is full programmable for an easy
fitting to the control of any type of yarn/application.
Types of IS3.. sensors for SMART 3000TW
The IS3.. Sensors are available in two typologies (W and N) to satisfy the specific
requirements of each installation/application.
Example: IS3NW485 means: New generation high sensitivity Narrow sensor.
Function of the IS3.. Sensors
The IS3.. sensors of the new generation have two signalling lights (upper green
LED, lower red LED) and a “Touch Light” button.
During the automatic numbering of the sensors (flashing green LED) it assigns the
displayed number (shown in the devices configuration screen) to the sensor.

Installation of the IS3.. Sensors
The installation of IS3.. Sensors is an extremely simple operation thanks the use of
multi-connector cables, which allows the chained interconnection of all sensors,
and their connection to the PSU 10A power supplies. To install the sensors operate
as follows:
!Prepare the adequate multi-connector cable.
"Open the rear cover of the sensor.
#Plug the male connector of the cable into the female connector of the sensor
(the reference key on the male connector must be positioned on the upper side
of the connector).
$Close the rear cover and secure the sensor using a M3 screw.
%Check that the yarn runs in the centre of the area #shown in the following
pictures.
