WARNINGS
1) Power down the yarn feeder’s power supply box mains switch before beginning any
power supply hook-up, maintenance or part replacement operations.
2) During standard machine operation, the yarn feeder may suddenly start up without
prior warning.
CAUTION: the orange lights do not signal that the yarn feeder is ON,
but that the feeder has gone into an alarm mode. Therefore, during
standard operation they should be OFF.
3) Before yarn feeder start-up, inspect it physically for damage (check the flywheel/the
eyelet/all moving parts).
Wear Personal Protective Equipment (gloves, shoes) during transportation and
installation of the feeders and the power supply kit, if any, to avoid crushing hazards in
the event of a fall.
4) Strictly avoid touching any moving part during feeder operation.
Do not wear clothes and clothing accessories that are likely to get caught in the moving
parts. Gather up long hair.
5) Lubricants may be used to make the yarn slide more easily. The user must refer to the
Material Safety Data Sheet of the products used. Keep the feeder clean.
6) Only use the original L.G.L. Electronics spare parts and accessories.
7) Any repairs to the feeder’s electronic parts must be performed by appropriately qualified
personnel, regularly authorised by L.G.L. Electronics accordingly.
8) Yarn feeders that are moved from warehouse storage into a warmer knitting 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.
9) Never pick the yarn feeder up by its yarn spool body or by its tensioning unit.

WARNINGS
ADVICE TO ALWAYS KEEP THE FEEDER IN PERFECT WORKING ORDER AND
EXTEND ITS SERVICE LIFE.
For an always satisfying performance of the yarn feeder over the years, we deem it advisable
to provide you with some simple tricks:
1. At the time of installation, passing from the store to the warm knitting environment,
Condensation may form on a yarn feeder that has been stored in cold places when this is
brought into a warm area.
Wait until this is completely dry before connecting it, otherwisethe electronic components
could be damaged.
2. Water and dampness may harm the electronic parts of the feeder. Operating the yarn
feeder for long time periods in extremely dump environments (dampness exceeding
80%) or using water-impregnated threads might quickly compromise the electronic cards.
Moreover, the feeder shall not be cleaned with water or similar substances.
3. Machines working in environments featuring a lot of dust require increased maintenance. By
prevent the knitting environment clean, you avoid residual dirt and dust from compromising
the performance of the machine by stressing the moving parts. The latter are protected, but
the accumulation of dust might result in a more difficult movement and, as consequence, in
early wear-and-tear.
4. We suggest storing feeders that are not used for long time periods in the special
polystyrene boxes, which ensure the best storage.
5. When the yarn feeder is being loaded, use the special heddle tool. Do not use other
tools, especially if made from metal, as he inlet sensor might be damaged, along with
any outlet brakes.

1  GENERAL FEATURES
Intended Use:
The ECOPOWER2 is a yarn feeder featuring separate coils, suitable for all types of
knitting machines or for textile machines requiring yarn feed-in with constant tension.
Optimised operation is provided with yarn counts ranging from 800 den (the thicker yarn
counts) down to 5 den (fine yarn counts).
IMPROPER uses
Improper uses are all those uses which are not expressly indicated among the design uses, namely:
- Working of yarns other than those specified
- Power supply of the machine not matching the specified value
- Use of the machine in an explosive atmosphere.
Operational features:
•Automatic speed adjustment designed to cover the machine’s yarn quantity requirements.
•Spool body winding reserve control by means of a magnetic feeler system.
•Yarn feeder and machine stop function if no yarn is detected at the feeder’s yarn input
(broken yarn or empty yarn bobbin).
•Kit KLS:
Feeder and machine stop function when no yarn is found on feeder outlet without using
mechanical sensors (yarn broken or out of the needles).
•The option of being able to fit on various tensioning devices based on the type of yarn
actually being used, at both the feeder’s inlet and outlet.
•Either vertical set-up or horizontal set-up assembly option, selectable based on requirements.
•Real-time detection and display function of the yarn consumption related to each machine feed
•ATTIVO electronic tensioner (optional). The operator sets the desired output tension, and
the system will maintain it, to avoid all tension changes depending on the yarn, the bobbin
and the like issues.
Technical specifications:
•Power supply by means of a direct connection with the machine, or through a power
supply box that is supplied separately by L.G.L. Electronics.
Power supply voltage data: V = 42-48 VAC three-phase Hz = 50/60 (AC version)
V = 57 VDC (DC version)
•Automatic yarn input speed control provided up to a maximum of 1000 m/min.
•Coil separation feature fixed at 1 mm (STD); 2 mm (Z1).
•Permanent magnet synchronous motor.
•Motor data:
Maximum power: 35 W
•Equivalent continuous A-weighted sound pressure level at maximum speed: <70 dB (A)
•Operation and storage conditions:
- Room temperature: from +10 to +40 °C
- Maximum humidity: 80%

1  GENERAL FEATURES
Never pick the yarn feeder up by its yarn spool body, by its top panel or by
its tensioning unit.
The yarn feeder is supplied in an appropriate polystyrene casing; please store the casing for
use during any future handling.
The yarn feeder features an input feeler that provides the following function:
•“Machine stop” function:
this function stops both the feeder and
the machine if no yarn is detected at
feeder input (broken yarn or empty
yarn spool).
CAUTION: the machine will not
stop if the feeder comes to a
halt.
The machine stop signal is
operative only if the signal
lamps are ON.

The optical sensor featured by the yarn feeder provides automatic speed adjustment based
on the quantity of yarn needed by the machine. For very fine yarn count processing (lower
than 40 den), the sensor requires DIP SWITCH settings (paragraph 2.4 refers).
The magnetic sensor that the yarn feeder is provided with has the function of monitoring the
yarn winding reserve on the spool body.

N.B.: Yarn feeders that are moved from warehouse storage into a warmer
knitting 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.
For installation of the yarn feeder onto the machine, proceed as follows:
VERTICAL SET-UP VERSION
Fix the feeder onto the appropriate support plate (F) and fit in the power supply flat cable (G)
as well; tighten in grub screw (H) until the flat cable is punctured.
IMPORTANT: To avoid damaging the electronic components, the installation
sequence illustrated in the figures below must absolutely be complied with exactly.
The brown cable (I) must be kept facing the signal lamps (C) (if the flat cable is supplied by LGL,
the brown cable (I) can be identified by the arrows (L) printed on the flat cable).
N.B.: Make sure that the support plate the yarn feeder is fixed onto is
provided with an earth connection, the same goes for the 48V AC threephase
power supply transformer star-connection.
