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.

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.

Intended use:
LGL TWIN is a yarn accumulator that incorporates an accurate yarn tension and feeding
speed control function. It can be used on knitting machines or textile machines in general to
monitor elastic and non-elastic yarns.
The main feature of TWIN is that it is very compact in size and can be installed in clusters/
batteries with a cascade chain connection, which provides savings in term of and wiring, and
an easier installation.
The operating parameters of the device can only be modified via Can Bus serial
communication, which provides a high degree of reliability and communication speed.
It can optimally work a variety of yarn counts ranging from 800 Den (coarse yarn) to
10 Den (fine yarn).
Warning
The power supply of the electronic board inside the device must range within the limits stated
in the “Technical Information” and, at all events, through the use of boards type-approved by
LGL S.p.A.
