Introduction Eltex EYE-System
Eltex EYE system detects the movement of the yarns. At the installation and whenever the quantity of
yarns or their positions are changed, a learn command is made. All yarn positions where the yarns are
moving will then be active. Thereafter if any of the active yarn positions does not have a moving yarn
when the machine is operating the EYE system will stop the machine.

Navigating in the operator terminal
This manual refers to “pages”
in the operator terminal.
Page numbers can be found in
the upper left corner on each “page”.
Explanation of Ramp up
Before the machine has reached the normal operating speed, it is possible to start the monitoring of the yarns using
special Ramp up parameters. This is called the Ramp up time.
If this is not necessary set Ramp up time to “0” in the installation procedure. Page 17.
(In the operator terminal page 1:834).
Tachometer function
If the machine is running with different speed it is possible to install a proximity switch as Tachometer.
This can then control the monitoring mode of the yarns.
The EYE system is set so that the detection is off when the machine speed is below “Ramp up start
speed”. When the speed is above this value the detection is on using the “Ramp up parameters”.
When the machine is running at normal speed above the “Normal run start speed” the normal
parameters is used.
Installation procedure for the settings can be found on page 16 in this manual.
(In the operator terminal page 1:824).

TH-0362 EYEsystem for creels Users guide 6 / 26
Sensor parameters:
How to check/set the parameters of the sensors:
Sensitivity and reaction time must be set correctly.
(If different groups have been set up the parameters can be set differently for each group).
Sensitivity (Gain) determines how easy the sensor can detect the yarn movement.
There are two different reaction times, “False Yarn Filter” and “Drop Out Delay”.
“False Yarn Filter” time determines how long time the sensor must sense a yarn movement before it is
considered to be valid. This is used to remove the influence of short false yarn movements.
“Drop Out Delay” time determines how long time the yarn movement signal must disappear before it is
considered as a stop of the movement of the yarn.
To set the sensor parameters:
On the main menu press “Parameters” Choose “Sensor Group Parameters”
Enter values for Sensitivity, False Yarn
Filter and Drop Out.
If the box “Enable copy of this group to
all” is checked the values in all other
groups will be the same.
If you are unsure about how to make the parameter settings, you can start trying with the figures
below.
Sensitivity Ramp up = 30 Normal = 20
False yarn filter Ramp up = 15 Normal = 30
Drop out delay Ramp up = 300 Normal = 100
When any field is selected for update you will be asked to enter password if “Password protection”
was selected during the installation. If so, select user “responsible” and enter “r” as password.
If anything has been changed, press the save button to save the new settings.
Return to main menu by pressing the “Main” button at the bottom.
Logged stop events.
From the main menu it is possible to select:
“Operational status” and then
“Logged stop events”.
Then the positions of the 10 last stop events
will be displayed.
With the optional EYE Analyzer software,
a lot more information can be displayed on
an external PC
.

Service / Fault finding
General for the EYE system
Indicator LEDs on the EYE sensors:
Common LED
on sensor Channel LED on sensor Machine status Description
Green on Off Machine is not
operating Power on, yarn detection off, no stop detected.
Green flashing Off Machine is operating Yarn detection on.
Green on Red flashing on
in one position Machine is stopped The EYE-system has
detected a yarn brake or
end out in this position.
Green on Red steady on in
one position Machine is stopped
The EYE-system has
detected a “False Yarn
position”. A yarn movement
in a position not learned.
Checking the status of the inputs and output on the MCU
·Inside the Master Control Unit just beside each
input and output terminal there is a LED which
indicates the status of each Input/Output(shown here in this photo).
·It is also possible to see the status of each
Input/Output on the Operator Terminal.
From the Main Menu select “Operational status”
then “MCU I/O status”. Page 1:120.
The EYE system stops and shows “Sens-Yarn fault” even if the yarn is correct
·Locate the position where the yarn fault is indicated.
If the yarn is not making any deviation when it is passing
through the sensor eyelet, try to increase the yarn angle.
·Check if the Sensitivity Setting is set too low.*
·Check if the Drop Out Delay is set too low.*
·Check if the “False Yarn Filter” is set too high.*
* See “How to set parameters” on Page 6.

TH-0362 EYEsystem for creels Users guide 8 / 26
The EYE system stops and show “False yarn position”
·Cleaning the Sensors or the machine with compressed air or using air splicers nearby when the
machine is operating can cause this fault indication.
·On the Operator Terminal and on the sensors, it is indicated which eyelet position is causing the
false yarn movement. Try to find the reason. For example, is there a yarn moving in an eyelet
that is not learned?
·Check if the sensitivity setting is set to high.*
·Check if the “False Yarn Filter” is set too low.*
* See “How to set parameters” on Page 6.
·Under “Parameters” it is possible to change the False Yarn Detection function. It can be set to
“ENABLED” at “START UP” then this check is done only once just after start up. It can also be
“DISABLED”, however it is recommended that this function is enabled (at least at start up) to
ensure the correct number of yarns are always in use.
The EYE system learns too many yarns
·Make sure that too many yarns are not actually threaded by mistake.
·The LED for each yarn position can be used to show learned positions. Under the Service Page
press “Show learned sensors”. Select the actual group. The LEDs will then show all learned
positions so you can find the eyelet(s) that is learned but has no yarn moving.
·If possible, try to find a reason that position without moving yarns has been learned.
·Check if the Sensitivity Setting is set to high.*
·Check if the “False Yarn Filter” is set too low.*
* See “How to set parameters” on Page 6.
The EYE system does not change to “Monitoring” after start of the machine
·Run mode signal is missing from the machine. Check the LED for run signal input.
See above “General for the EYE system”.(For run mode signal see Page 13 Hardware installation.)
·Connection settings between the “machine” and inputs have been changed.
See under installation page 16. (In the operator terminal page 1:830).
·There can also be another connection assigned as a running mode input. If there is more than
one running mode input, all of them must be on to turn the system into Monitoring mode.
The EYE system does not learn any yarns or does not relearn
Check the run, enable (synchronization) and learn input:
·If the system does not change to run mode when the machine starts, see the point under the
heading “The EYE system does not change to “Monitoring” after start of the machine” above.
·Press the learn button. Does the mode change to “Learn”?
If not the Learn signal is missing from the push button. Check the LED for this input.
See above “General for the EYE system”.
·Connection settings between the “machine” and input have been changed.
See under installation page 16. (In the operator terminal page 1:830).
Check the sensor addressing:
·Go to installation menu, select “Sensor adr setup”.
Does it show correct number of sensors?
Check that the sensors in the group is connected to the machine:
·Go to installation menu, select “Sensor group-mach”.
On page 1:860, check that “Group 1” is linked with “Machine 1. The box must be checked.
The Operator Terminal show “LIN com error”
If there is a fault with the modular cables connecting the sensors, the LIN com error will appear on the
Operator Terminal. Also, the “ERR” Led on the Master Control Unit will flash. The message on the
Operator Terminal is indicating in which LIN-bus and on which sensor “B pos” it has detected the fault.

TH-0362 EYEsystem for creels Users guide 9 / 26
How to run “Sensor addr setup” command
From the main menu, press “Service”.
You will then be asked to enter a
password.
Enter “s” and press Enter. Note that it
should be a lower-case s. Press the button “ Sensor addr setup.
Make sure all sensors are connected to
the master control unit.
Press “Set sensor addresses”.
The sensors will now be automatically
detected in the system.
Check that the correct number of
sensors are displayed for each LIN-bus.
How to enter the “Learn” command
When all desired yarn has been threaded the EYE system has to learn in which positions yarns will be
moving
If “Learn” push button has been installed on the machine just press that one.
Otherwise enter on the Operator terminal as below:
From the main menu, press
“Operational status”. On page 1:100 Press the button “ Creel op status + learn”.
On page 1:170 Press the button
“Learn sensors”. The text in “Mode” box
will change to “Learning”.
Start the machine.
If the EYE system has been configured to stop after learning, the machine will stop and on the
Operator terminal page 1:170 will appear.
If the number of yarns are correct, then start the
machine again to continue.
If not check if the machine has been threaded up with
wrong number of yarns.
If not check possible faults on page 8 in this manual.

Hardware installation:
1. Mount the Enclosure 10320 containing the Master Control Unit (MCU) 11710 and Operator
Terminal 11797, on a suitable position.
2. Mount the EYE sensors. Be sure that the yarns are touching
the ceramic eyelet and are making a small deviation when
passing the sensor.
3. Connect cables 65300 between the sensors and to the LIN1 – LIN6 connections on the MCU
11710. If EYE sensors are used, maximum 12 sensor can be connected to each LIN-bus.
4. Connect a machine run signal (running mode) to the DI1 input on the MCU 11720. This is to tell
EYE system if the machine is running or not.
The run signal should be a relay signal which changes state when the machine start and stop.
Connect the relay contact between terminals + and 1 on DI1.
The relay contact can either be closed or open when the machine is running.
The function of the DI1 can be set on the Operator Terminal.
For testing this signal can be done with a switch and controlled manually.
5. Connect the stop output to the machine. The relay has two alternating contacts available.
Normally the output is set so that the relay switches 1 second at a stop. This can be set in the
Operator Terminal.
6. Fit the Power Supply in the control box of the machine.
(It is possible to have the power supply also be fitted in the Enclosure 10320, if so, it should be
specified on the order)
7. Connect the 24V DC voltage from the power supply to the ON/OFF switch in the 10320
Enclosure.
8. Turn the power on to the system.

How to configurate Inputs and Outputs
General preferences for the installation.
With this setting a password will be required to
change sensor parameters.
Configuration of the standard inputs. If DI1 is
used for “Run mode” Enter like this.
DI7/PI1 can be used for external learn button.
You can start with the value on Run mode 5000 =
5 sec.
Configuration of the outputs.
DO5 will function as indication for total machine
with the setting “Alarm” and “Alarm delay” = “0”.
DO6 is used for the relay. With this setting the
relay will switch for 2 seconds at a stop signal
from the EYE system
The Tacho fuction is normally not used when the
EYE system is installed on a creel.
Configuration of Tacho input.
Enter at which speed the EYE system should start to monitor the
yarns with “Ramp up” settings* and at which speed with “Normal”
settings.
Select “Next”.
There is the possibility to invert the inputs or
outputs for test proposes or for real needs. In this installation only one machine is used.
At least the boxes as below has to be checked.
If the outputs 1 and 2 should be used for indication lamps, left and
right, then these two boxes must be checked.
If tachometer is used and connected to input PI2, then the box PI2
must be checked.

TH-0362 EYEsystem for creels Users guide 17 / 26
It is possible to have special “Ramp up”
parameter settings during start before the
machine has reached full speed
You can start with the value 10 000 = 10 sec.
(“Ramp up” is explanied on page 5).
If the Tacho input is used this page has no function, you can set to 0
(zero).
The Learn process is here configured to start by
selecting “Learn” on the Operator Terminal (or
pressing the Learn button if this has been
installed). The machine will with this settings stop
when the learn is finished.
It is possible to set the EYE to allow some yarn to
be missing without stopping the machine.
This function is normally not used when the EYE -
system is installed on a creel. Set to zero.
On an EYE-System with more than 72 EYE
sensors, a Slave Contro Unit (SCU) must be
added. Then it is necessary to press the button
“Set Slave Control Unit/ETM addresses”.
Press the “Set Sensor addresses”. The system will
detect all connected sensors and positions
(channels) in each LIN bus.
(The figures will be like this if it is only as few sensors as in the
example on next page)
If any sensor is replaced in the system, it is
needed to run this command again.

TH-0362 EYEsystem for creels Users guide 18 / 26
Setting up Alias
It is possible to give a name (Alias) for each yarn/position. This will be displayed on the Operator
terminal at any kind of yarn fault.
If you wish, you can leave the alias part for now and continue on “Setting up groups” to have the system
started up sooner.
However be sure to make it later because alias name are a big advantage fo the operator.
Depending on the creel configuration and how you like to identify the yarn positions the data to be
entered in Operator terminal will be different.
Below we describe one example which is intended to be a help to enter your specific data.
If a creel has one left and a right side and has 6 vertical levels and has 16 yarns in each level each side,
the EYE sensors can be fitted as in the drawing below.
The alias name can have maximum 6 characters and it can be like this: L5-07. “L” is for left side, 5 is for
the fifth vertical level and 07 is the yarn position in that level.

TH-0362 EYEsystem for creels Users guide 19 / 26
Example: . With this setting the yarn positions in
the upper left level will be numbered from
L6-01 to L6-16.
Please remember: When the Alias has been
entered, then press “enter” on the KEYPAD
and after that press “Apply alias”each
time a new section has been entered.
With this setting the yarn positions in the left 5th
level will be numbered from L5-01 to L5-16.
Do not forget: press “Apply alias” before
entering the next section
With this setting the yarn positions in the upper
right level will be numbered from R6-01 to R6-16.
Press “Apply alias”
Repeat to enter alias like this for each level each
side.
With this setting the yarn positions in the lowest
right level will be numbered from R1-01 to R1-16.
Press “Apply alias”
It is possible to verify the ALIAS by pressing the
“Verify alias” button. When selecting “Verify Alias” this page 1:846 will appear. Use the up/down arrows to shift between
the LIN buses and the sensors (B Pos). Here it is
also possible to edit alias of individual
channels/eyelets.

TH-0362 EYEsystem for creels Users guide 20 / 26
Setting up Groups
It is possible to divide the yarn positions in
different groups. For example if the yarns has
different yarn counts, different parameters can be
set for the groups.
Or if sometimes the whole creel is used and
sometimes only a part of the creel. Then the
yarns which are only sometimes used can be
group 2
During operation it is then very easy to enable or
disable desired groups.
With this setting and by pressing “Apply group” all
sensors will be connected to group 1.
If 2 groups are selected, the “Range” setting has
to be done accordingly.
It is possible to verify the groups by selecting the
“Verify goups” button.
By pressing the “Show group assignment” button
the LEDs on the sensors will turn on when the
corresponing group is selected in the window
“Group no”.
It is necessary to link each group to correct
“machine”. In this case Group 1 to Machine 1.
It is also needed to select the type of sensors on
each group.
In this case the window should read:
“Yarn break sensor”.
Here it is also possible to enter a name of the
group.
If a Group 2 has been created, also this group
has to be linked to machine 1.
