1) Switch off the power supply box and the yarn accumulator before starting any part
connection, maintenance or replacement.
2) During standard machine operation, the yarn accumulator may suddenly start up without
prior warning.
3) Before start-up, inspect the machine for physical damages (flywheel/ bush/moving parts)
4) Strictly avoid touching any moving part during operation.
5) Due to the high accuracy and sensitivity of the tension sensor, mobile or cordless phones
might interfere with it. Operation of the device and the sensor is not affected.
In any case, to avoid interference, we recommend that you keep a minimum distance of
3 metres.
6) Only use original L.G.L. Electronics spare parts and accessories.
7) Any repairs of electronic parts must be performed by appropriately qualified personnel,
duly authorised by L.G.L. Electronics accordingly.
8) Yarn accumulators that are moved from warehouse storage into a warmer weaving
mill environment may develop condensation. Please wait until they are completely dry
before connecting them up. Failure to do so may damage the electronic components.

TIPS TO KEEP THE YARN ACCUMULATOR IN GOOD WORKING ORDER AND
EXTEND ITS SERVICE LIFE.
For you to achieve and maintain a satisfactory performance of the yarn accumulator, we
suggest you should follow some simple steps:
1. Yarn accumulators that are moved from warehouse storage into a warmer weaving mill
environment may develop condensation; please wait until they are completely dry before
connecting them up. Failure to do so may damage the electronic components.
2. Water and moisture are harmful to the yarn accumulator’s electronics. Keeping the yarn
accumulator operating for long periods of time in very humid environ-ments (humidity ≥
80%) or using yarns impregnated with water may quickly result in damages to electronic
cards. Moreover, never clean the yarn accumulator with water or similar liquids.
3. Machines working in very dusty environments require greater maintenance. A clean
workplace clean can prevent residual dust or dirt from negatively affecting machine
performance by stressing its moving parts.
The latter are protected, anyway dust accumulation might result in hindered movement
and, hence, early wear
4. We recommend that you store yarn accumulators that are not used for long periods of time
in the appropriate polystyrene boxes, which guarantee optimum storage conditions.
5. When the yarn accumulator is being threaded, used the appropriate heddle tool. Do not
use other tools, especially metal ones.

1  GENERAL INFORMATION

9
The TWIN device is available in 2 different versions, one featuring a yarn recovery option
(up to 20 cm), and another version which does not feature this option (the yarn feeding wheel
only turns forward).
In the yarn recovery version, the separating pin is not fixed to the accumulator body, but to
a wheel (coaxial with the yarn feeding wheel) and is free to rotate to an angle smaller than
360°. With the accumulator in normal operation mode, the feeding wheel supplies the machine
located further downstream with yarn, turning clockwise. In this case, the separator wheel
remains in an upright position.
When recovery is needed, the yarn must be pulled towards the accumulator, therefore the yarn
feeding wheel turns counter clockwise thus trailing the separator wheel and, consequently, the
separating pin itself.

2.1 INSTALLATION OF YARN ACCUMULATOR
N.B.: Yarn accumulators that are moved from warehouse storage into a
warmer weaving mill environment may develop condensation; please wait
until they are completely dry before connecting them up. Failure to do so may
damage the electronic components.
To install the yarn accumulator onto the machine, proceed as follows:
1. Place the flat cable onto the outer edge of the support ring and fix it by means of straps.
The text “FEEDER CONNECTOR SIDE” on the cable must be read on the correct reading
end, and not reversed; the arrows must be turned downwards.

2.2 CONNECTIONS
Each TWIN device is equipped with an “Receptacle” input connector (A) and a “Header”
output connector (B) having the same “pinout”, which enables a cascade connection of
several devices in a “battery” embodiment.
The device topping each battery must be inserted into the special clamp that enables
connection to a 4-wire flat cable.
Each battery can be composed of a maximum of 4 devices.

2.2.1 Electrical connection
Owing to the lack of a display unit, “Standalone” use is not possible. The device can only
operate in systems with a Can Bus communication line and Master devices for the setup of the
operating parameters.
For each single device, the signal arrangement of both connectors (J1 and J2) is as follows:
No. of pins on J1 Signal description
1CAN L
2CAN H
3+Vdc Alim.
4GND
2.2.2 Connection problems
The TWIN devices are designed to ensure that, in the event of connection errors, they are not
damaged. Of course if voltage ratings applied range within the limits set for the device. The
main connection problems are listed below.
- Inverted power supply: If the “+Vdc Alim.” power supply is connected with inverted
“GND”, the device will not turn on.
- GND failure: If only the GND contact is missing from the device, the latter will not turn
on. However, as it is still connected to the power supply line, it prompts the Can Bus
communication line to rise towards “+Vdc Alim.”. In this condition all the other connected
TWIN units cannot communicate, but detect the high-voltage fault on Can Bus and show it
via the blinking of “Can Bus Fault” (see dedicated chapter).
Please bear in mind that in this condition the termination resistor of the Can Bus line might
be damaged.
- Short circuit between Can Bus and “+Vdc PS.”: If a short circuit occurs between
the Can Bus communication line and the “+Vdc Alim.” power supply, the TWIN devices
cannot communicate but detect the high-voltage fault on Can Bus and show it via the
blinking of “Can Bus Fault” (see dedicated chapter). Please bear in mind that in this
condition the termination resistor of the Can Bus line might be damaged.
- Short circuit between Can Bus and GND: If a short circuit occurs between the Can
Bus communication line and the “GND” contact, the TWIN devices are not in a position
to communicate. Indeed, if the short circuit only occurs between one of the two Can Bus
signals and the GND, then in given conditions communication is still possible, even though
reliability is not guaranteed.
- Short circuit between Can H and Can L: If a short circuit occurs between the two
signals of the Can Bus communication line, the TWIN devices cannot communicate.

2.3 USER INTERFACE ON “BUTTONS AND LEDS
The TWIN device is equipped with 2 buttons and 2 signal lights.
The upper button, blue in colour, is defined as the ON/OFF button and is used for the Turn
ON/Turn OFF functions as well as for the main functions.
The lower button, Black in colour, is defined as the CONFIG button and is used for the
advanced configuration functions.
The signal lights, one on the right and the other on the left, can take two different colours,
Green and orange. They can also take a yellow colour when they are turned on at the same
time. The state of the device is conveyed to the user by means of the above-mentioned LEDS
with fixed lights or various forms of blinking.
See the relevant chapter dealing with LED signals.

3.1 BASIC USE OF THE DEVICE
Once turned on, the TWIN device runs an initialization and diagnostic check. If at this stage
no issues are found, the device sets itself to the RUN mode.
In the RUN mode the following condition will be found:
• Green LED ON;
• Orange LED OFF;
• Motor and Yarn tension sensor enabled;
• Can Bus communication enabled.
3.2 “WYW” START-UP AND THREADING
Once turned on and before starting the threading, you need to set the device to WAIT YARN
WINDING (THREADING) – WYW mode.
To reach this mode, hold the ON/OFF (Blue) button pressed for 1sec and then release it.
In the WYW mode, the following condition will be had:
• Green LED off;
• Orange LED ON;
• Motor enabled at limited speed
3  STARTUP AND WINDING

18
At this point it will be possible to insert the thread into the special eyelets and wind it around
the yarn feeding wheel.
THREADING: Wind the yarn around the feeding wheel as shown in the figures,
taking care that the first coil is run below the separation pin, whereas for the
following coils the yarn shall run above the pin (A). Insert the yarn into the
output yarn guide bush so that the yarn runs on the load cell. (3).
The number of coils to be wound around the feeding wheel varies as a
function of the yarn type. The following values are given as an indication:
− Bare Lycra: 1-2 coils
− coated Lycra, cotton, nylon and polyester: 3-5 coils
Once the threading is over, click on either button to re-enable the device and set it back to
the RUN state.
N.B.: When the device is in WYW mode, the “Stop” string will be read via Can Bus.

from WYW to SLP Hold ON/OFF pressed for 1sec.
N.B.:
The device can be set to the WYW state also through a special command via the
communication can bus by sending the related value to the “Command” parameter (See
dedicated table in chapter 4.11).
3.3 CELL OFFSET CALIBRATION (TENSION SENSOR)
As already known, the Offset Cell calibration procedure envisages that the yarn is removed
from the sensor.
To prevent the motor from being set in motion while the yarn is being removed, you need to
set the device to the WYW mode.
Once in the WYW mode, remove the yarn from the tension sensor.
After that, to perform the calibration, press both buttons for 2 seconds and release them
as soon as the Orange LED starts “flickering”.
During this stage the device will perform the real calibration, therefore it is good rule to
avoid touching the device not to affect the acquisition.
At the end of the flickering of the Orange LED,, if the calibration has been successful the
device will generate an “Approval” signal with a quick double blinking of the green LED

and then will set itself back to WYW mode to allow the yarn to be placed back on the
sensor. If the calibration proves to be Incorrect, the device will set itself to the Fault mode.

N.B.:
The Cell Offset Calibration can also be executed by means of a special command via can
bus communication. To do this, you must first remove the yarn from the cell, after which you
must send the corresponding value to the “Command” parameter (See relevant table in
chapter 4.11).
3.4 DESABLING THE DEVICE. “SLP” SLEEP MODE
When the device is installed but is not in use, it can be disabled to prevent it from actuating
the motor from running or that textile alarms are sent to the machine needlessly. This condition
is defined as SLEEP(SLP) mode.
When the device is in SLEEP mode, the motor and the tension sensor are disabled. If the
device is in the Fault “FLT” state, it will be possible to shift to SLEEP to reset the signal. There
are, however, some serious Fault conditions that do not allow the device to shift to SLEEP, or
others that, upon re-enabling the device, will still show the Fault signal.
As regards the “CBF” Can Bus Fault indication, concerning the detection of a high voltage
along the Can Bus line, the device cannot be set to the SLEEP mode.
