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

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

6
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.

The ECOSMART feeders incorporate a dual communication system with the weaving machine. They can either
operate with the traditional system and with the new Can-Bus protocol, provided that a dedicated Cable - Power
Supply Box equipment is available.
Notably, if the feeder operates with the Can-Bus protocol, it may exchange a greater number of data with the
weaving machine and hence incorporate new features.
The PATTERN PREVIEW, which the feeder can use to improve speed adjustment, is an instance of this improved
feature.
The weaving machine communicates in advance which feeder will be selected and for how long it will operate. Then
the feeder will use this information to optimize its acceleration ramp and set a dedicated winding speed in shorter
time lags.

2.3 INSTALLATION AND START-UP OF THE WEFT ACCUMULATOR
N.B.: 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, oth-
erwise the electronic components could be damaged.
To install and start-up the weft accumulator, follow these steps:
1) Fix the accumulator to its stand using the clamp provided.
N.B.: Make sure that the stand used to hold the weft accumulator is connected to the earth
system.
2) Position the weft accumulator so that the weft is as straight as possible between this and the loom.
3) If necessary (e.g. highly twisted yarns, snarled yarns, etc.), fit the input tensioner to the weft accumulator if not
already fitted on the creel.
4) Connect the weft accumulator to the pneumatic circuit (only if fitted with pneumatic threading).
5) Switch off the power supply box before connecting the weft accumulator.
This is necessary in order not to damage the weft accumulator electronics.
6) MeSwitch off the weft accumulator by turning its 0 - I switch to 0.
7) Connect the weft accumulator cable to a power supply box socket.
N.B.: If the box is fitted for the “Exclusion of broken wefts” function, the power supply
cable must be connected to the socket marked with the same number as the finger of the
loom to be fed by the weft accumulator.
8) Switch on the power supply box.
The green led on the accumulator top panel will flash briefly and then go off (Reset).
9) Set the weft accumulator direction of rotation and adjust the coil separation.
The default settings for the accumulators are Zrotation.
10) Now thread up the weft accumulator using the special weft taker provided or the pneumatic threading system,
if fitted.
11) Having threaded up the accumulator, switch it on by turning switch 0 - I to I and the weft will start to be wound
around the weft spool body.
