weft accumulator
L.G.L. Electronics is gratified by your choice
and thanks you for the preference.

CAUTION
1) Switch off the power supply box and the weft accumulator before starting any connections,
maintenance or replacements.
2) Switch the weft accumulator off before carrying out any adjustments.
3) If the weft accumulator is fitted with a kit for pneumatic threading, discharge all the compressed air
before removing the rear cover.
4) The weft accumulator can be started, if enabled by the loom, at any time during normal operation,
without forewarning.
5) Check the feeder to ensure it is intact (flywheel, flywheel bush, moving parts).
6) Never touch any moving parts when the equipment is running.
7) The machine is not fit to operate in work places featuring high explosion risks.
8) Condensation may form on a weft accumulator that has been stored in cold places when this is
brought into a warm area. Wait until this is completely dry before connecting it, otherwise the
electronic components could be damaged.
9) Never take hold of the weft accumulator by the weft spool body or the weft feeler unit.
10) Only use original L.G.L. Electronics spare parts and accessories.
11) Electronic parts must only be repaired by suitably trained personnel authorised by L.G.L. Electronics.

ADVICE TO ALWAYS KEEP THE FEEDER IN PERFECT WORKING ORDER AND EXTEND ITS
SERVICE LIFE.
For an always satisfying performance of the weft 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 weaving environment, Condensation
may form on a weft accumulator 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 weft 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. Upon installation, before injecting voltage to the feeder, ensure that the round wires are all hooked-up.
Any insufficient grounding may damage electronic components.
4. Machines working in environments featuring a lot of dust require increased maintenance.
By prevent the weaving 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 accumula-
tion of dust might result in a more difficult movement and, as consequence, in early wear-and-tear.
CAUTION

5. In the presence of dusty yarns, residual dust or thread may settle on the various parts of the weft feeder.
A weft feeder that is particularly dirty is likely to compromise the fabric quality by leaving deposits on
the threads that is introduced. In order to improve the fabric in quality as well as the machine overall
performance, it is good rule to routinely clean the mechanical moving parts:
• By blowing compressed air from the ceramic of the flywheel, you may clean the shaft channel and
remove any residual dust from the input sensor. Warning: Before using compressed air to clean
the feeder, ensure you remove the thread from the drum. If you use compressed air with the thread
wound up on the drum, you actually risk having the thread get in and accumulate between the
flywheel and the drum.
• The drum and the flywheel can be periodically dismounted to remove any residual thread and dust.
6. We suggest storing feeders that are not used for long time periods in the special polystyrene boxes,
which ensure the best storage.
7. When the weft feeder is being loaded, use the special weft taker.
8. If the weft feeder is equipped with a TWM brake, always open the brake carriage when you introduce
the loading weft taker. Thus, you avoid taking the risk that the weft taker damages the brake unit.

1.1 MAIN PARTS - CONTROLS AND ADJUSTMENT POINTS
Main parts:
CONTROLS/ADJUSTMENTS FUNCTION
A SWITCH 0 - I • Switches the weft accumulator on and off.
B
SWITCH S - 0 - Z
The switch has three positions:
S, 0 (zero) and Z.
•For setting the direction of rotation of the motor.
N.B.: In cases when the “Loom Stop” function is enabled on the loom,
the intermediate position 0 (zero) of the S - 0 - Z switch allows
for switching off the weft accumulator that is not used without
stopping the loom.
CLED • This comes on and stays on if there are no faults when the accumulator is switched on.
• This flashes if there are malfunctions (see paragraph 10 “Trouble-shooting”).
D
PNEUMATIC THREADING
BUTTONS
These control the pneumatic threading.
•Button DPfor partial threading (up to weft spool body).
•Button DFfor total threading.
ECOIL ADJUSTMENT
BUTTON
•This is used to vary the separation of coils (see paragraph 3.5 “Setting the direction
of rotation and adjusting the separation of the coils”).
FRELEASE PUSH-BUTTON • This is for releasing the output tensioner.
GADJUSTMENT KNOB •This is for adjusting the intensity of the output tensioner.
