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.
