- OVERVIEW
OVERVIEWOVERVIEW
OVERVIEW
System components
The SMART 200 TTS system consists of a control/programming Terminal and a
variable number of IS3W/TTS type sensors (up to 200) connected to the terminal
using specific interface cables.
System’s Operation Principles
The sensors’ detection features: yarn collection speed (SPEED), max number of
twisting per inch (meter)(second) (TPI(M)(S) max), min number of twisting per
inch (meter)(second) (TPI(M)(S) min) sensitivity (SENS) depend on the type of
yarn (article) being processed.
These features must be programmed on each sensor and can be changed according
to the article which is being processed.
The terminal has in fact the function of programming and, as conditions change, it
can vary the sensors’ features, according to the quality control requirements;
furthermore, it has the function of displaying, by means of bars or histograms, the
number of twisting detected by each sensor on the yarns being controlled.
Special Features of SMART 200 TTS system
The SMART 200 TTS system has a set of unique features which make it a true
microcomputer dedicated to the yarn quality control.
SMART 200 TTS is a fully parametric system; this means that for each type of
defect the user can freely define the desired parametric values. When these values
are exceeded, the system signals a fault condition.
The programming (and reprogramming) phase of the sensors is limited to an
extremely quick and easy operation. It consists of communicating the name of the
article to the sensor or to a specific set of sensors on the machine, which the
sensor(s) will have to detect.
The main advantages of this solution can be summarised as follows:
Absolute flexibility:
thanks to the possibility of quickly changing the sensors’ program, according
to the article to be processed.
Maximum simplicity:
concerning the installation as well as system programming and administration.
Maximum accuracy:
the possibility of programming the detection capability of the sensors
according to the type of yarn to be processed guarantees a perfect symbiosis
between sensor and yarn.

OPERATION
SMART 200 TTS Terminal Features
As in all SMART BTSR systems,the operation of SMART 200 TTS 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 hand side of each button there is a red LED, which indicates that the
button is pressed down.
The display screen includes two separate zones used respectively for displaying
operator messages or graphics 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 SMART 200 TTS system.

Operation
- 3.2 - SMART 200 TTS
1. ENTER button
It allows you to activate the function selected from the menu (indicated by the
symbol >), to move to the programming of the displayed function or to confirm the
setting value displayed on the messages screen.
2. RESET button
It allows you to return to the previous level of the menu (upper level), without
continuing with the currently selected function, or without confirming the value of
a setting entered by mistake.
3. NEXT CY button
During navigation within the menus this button allows you to select the next
option within the same menu level; this button has a cyclical function in the
sense that when the last choice from the menu has been selected, it returns to the
first option of the same menu.
When alphanumeric data are entered (for instance the Article Name or Keycode
access), this button allows you to increase the character displayed where the
cursor is located, according to the following cyclic sequence:
When entering numeric data (for example the number of sensors) it allows you

SMART 200 TTS -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 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, it shows all the necessary information to guide the
operator step by step through the programming phase and interactive management
of the system.
When the displayed lines refer to the menu items, the selected one is indicated with
the symbol >.
The presence of a flashing cursor (---) indicates the position where the operator
can enter an alphanumeric character or variable setting which will replace the value
currently displayed.
When you select the GRAPH function from Main Menu, this area is used to
graphically represent the number of twisting detected by a specific sensor, or to
compare by means of a histogram the readings of multiple sensors (8, 12, 16).
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 parameters currently set in the
system. In this phase the message display indicates CONTROL OK.
The ERROR label indicates that an error has been detected during normal
operation of the system. In this case the Message area shows the type of error
detected (for further information please refer to Operations Sequences in this
chapter and to chapter 4 – Troubleshooting and Maintenance).
The labels P1 .. P5 indicate the hierarchic level of the menu in which you are
operating. P1 is the highest level, P5 is the lowest hierarchical level. To move
from an upper to a lower level you must normally press down the ENTER button,
while to do the opposite, i.e. going from a lower to an upper level you must press
the RESET button.

IS3W/TTS Sensor Features
The IS3W/TTS devices are electronic sensors able to detect, due to sophisticated
control technique, the image variation, signalling possible failures detected during
the twisting process of yarns. Thanks to the image variation technique,
ambient/yarn conditions like humidity, conductivity and machine vibrations cannot
influence the IS3W/TTS device, furthermore the image variation technique
requires no contact with the yarn and allows a perfect monitoring without affecting
the characteristics (e.g. tension) of the yarns. IS3W/TTS devices can be used for
yarn quality control (under both static and dynamic conditions) which, thanks to an
innovative patented technique (Smart Scanning Sensor) combined to the advanced
yarn control terminal SMART 200 TTS don't need complex wirings and long
installation times, allowing you to manage up to 200 positions.
The IS3W/TTS devices are very easy to use as they are ready to accommodate a
large variety of accessories that make them suitable to the quality control of any
type of yarn.
Function of the IS3W/TTS Sensors
The function of IS3W/TTS is to control whether the number of twisting applied to
the yarn is within the expected range for the article being processed.
Depending on type of yarn and application, the user can define the minimum and
maximum number of acceptable twisting and, accordingly, program the sensors in
such a way that, when exceeding the defined values, they signal the failure and, if
required, stop the position (STOP output).
In additional the sensor can be configured to perform the control in two different
modes (TT or TB):
1. TT Mode: the sensor analyses the profile of twisted yarns running inside the detection area
and calculates the number of twisting, thanks to the image variation.
In this operating mode, the two yarns, already twisted, run continuously inside the
detection area as shown on figure 1.
2. TB Mode: the sensor analyses the entry/exit movement (balloon) of one of the two yarns
(to be twisted) to/from the detection area, to calculate the number of twisting.
In this operating mode, the internal yarn runs outside the detection area, while the
external yarn enters/exit the detection area, according to the balloon, as shown on
figure 2.
The TT mode is suitable for non hairy yarns (tyrecord) showing a regular profile, while the TB mode is
suitable for hairy yarns that could alter the profile.

Connection cables
The IS3W/TTS are available as standard version without connection cable. In this
case the wiring can be made using a multi-connector cable MA../..CR which
considerably simplifies the installation in most applications.
For particular application, however , the sensor can be delivered with built-in
single connector cable.
Installation of IS3W/TTS sensors using multi-connector cable
Using multi-connector cable you can interconnect up to 40 sensors for each chain
and then connect the chains to PSU 10 A power supply or directly to SMART 200
TTS terminal (in case of single or double chain). To perform the installation
operate as following:
Select the appropriate multi-connector cable.
Open the small cover on the rear side of sensor.
!Insert the cable’s male connector into the sensor’s female connector (the
reference tab on male connector must be faced towards the upper side).
"Close the small cover and secure the sensor using M3 screws.
#Ensure that the yarn runs in the middle of detection area .

Installation of IS3W/TTS sensors with built-in cable
When you use the IS3W/TTS sensor with built-in cable, independently of the type
of connector used, the wire assignment will always be the following:
Sensor – Operator and Sensor – System Interfaces
Sensor – Operator Interface
The interface between sensor and operator consists of the following:
1 optical button (Touch Light) used by the operator to number the sensor
during the first installation or replacement, to activate/deactivate the sensor and
to reset the sensor after a failure.
To switch the touch light, just skim it with a finger.

Operation
- 3.8 - SMART 200 TTS
Sensor –System Interface
The sensor communicates with SMART 200 TTS terminal and with the textile
machine through the following signals:
TX-RX: Is the bi-diretional communication line between sensor and
SMART terminal, used for sensor operation parameters
programming, for sensor’s test and for all the other real-time
communications between sensor and terminal.
STOP Output: The STOP signal is an OPEN COLLECTOR Output through
which the IS3W/TTS sensor signals the yarn control status
(number of twisting within the minimum-maximum programmed
range or number of twisting higher than the maximum threshold
or lower than the minimum threshold).
The STOP Output can be configured as a Normally Open (NO) or
Normally Closed (NC) signal and, in addition, it can be
configured either as Continuous signal (CONT) or as a 2 seconds
Pulse signal (P2s) or 10 seconds Pulse signal (P10s).
Examples:
Normal Operation = (the yarn runs normally and the number of twisting is within the
programmed range TPX MAX and TPX MIN)
Delay Control = Delay programmable via software
Failure Reset= Either Manual through (Touch Light) or Automatic if RES-MA
parameter is set to Auto.
When the sensor is de-activated, the STOP Output is always in Normal
Operation condition therefore, in case of NO configuration it will always be
an open circuit.
