WARNING!
-
Condensation could form on the Weft Feeder when it
is moved from the cold environment of
the warehouse to
the warmer environment of the weaving room. Make sure
that it is
completely dry before connecting to power.
-
Provide proper information to the people operating the
weft Feeders.
-
The installation, connection, adjustment, and maintenance of the Weft Feeder has to be
performed by
technically qualified
personnel.
-
The Loom's main power switch MUST be switched
OFF before any replacing
or
connecting
operation.
-
Caution must be taken on the close vicinity of the
Feeder. In normal working condition, it can
start running
without prior warning and the moving parts might
cause
injuries.
-
Repairing any electrical part of the unit has to be carried
out by
Roj
s.r.l
.
authorized personnel.

GENERAL INFORMATION
Super Elf X3 description
SUPER ELF X3
is a Weft Feeder with
yarn separation
and direct
CAN
-
bus
communication
with the Loom
Control. The new Permanent Magnet motor and the
Reserve sensor allow very
fast reaction and accurate yarn storage control on the spool
body. The new and innovative
barrier optical sensors
guarantee best performances in
dust environments and with very
fine
yarns.

Pulsar HP brake description
The Pulsar HP device, performs the
following two functions:
Breaking function:
to reduce the tension pick to the weft when the same is
stopped by the
Electromagnet pin. This is to avoid the following problems:
a. weft breakage at the end of the insertion
b. weft loops or slack picks in th
e fabric.
Pull back function:
after the yarn cutting, yarn is pulled back into the nozzle.
This is to avoid that the weft gets tangled in the next weft to be inserted by the
contiguous nozzle.

Features and
Characteristics
o The Weft Feeder can be set for rotation S or Z depending on the yarn
twist.
o Yarn separation is adjustable from 0.7 mm to 2.2 mm.
o Coils detection by means of photocells (Barrier system).
o Storage detection with an integrated
photocell (barrier system).
o Input Weft breakage control through a photocell integrated in the Super
Elf X3, or through
external TFE6 weft Stop Motion device.
o Weft length adjustment, by setting the spool body diameter and the
number of coils to be
rel
eased at each insertion.
o Range of weft lengths: from 64 to 672 cm.
Note
: Weft lengths ranging from 87 to 96 cm CANNOT BE MEASURED.
o CAN BUS communication protocol with the loom Control.
o Pulsar HP brake control.
o Full and half weft threading by me
ans of a pneumatic system.
o New Electromagnet design.
o Reserve Storage position Photocell reliable also in dust environments.
o Permanent Magnet motor for more accurate speed control, faster
acceleration, full torque at
all speeds and lower energy
consumption.
o Sealed motor, photocells housing and cable connections are IP63 Water
Proof standard
o New anti
-
balloon design with reclining Funnel simplifies maintenance and
optimizes space requirements for multi
-
color applications.

INSTALLATION AND CONNECTION
Voltage Supply Box and Weft Feeder installation
1.
Fix the Voltage Supply Box to the Stand by means
of the proper
brackets.
Note
:
Minimum distance from the Box to the floor must
be 20 cm. (see fig.
1
)
2.
Install the Weft Feeders on the Stand by means of
the existing clamps.
Note
:
The feeders must be positioned on the stand according to the type of installation. It
is
important that
yarn path is as straight as possible between the Feeders
and the loom
nozzle
s
.
3.
Place the Feeders' cables and the air tubes inside the tunnel of the Stand.
Electric
al
connections
1.
Connect the Feeder's cables to the Voltage Supply Box
by
following the numeric
correspondence to the loom nozzles (Feeder working with the weft threaded in
nozzle 1 must
be connected to the position 1 of the Voltage Supply Box; etc.).
2.
Connect the CAN
BUS cable to the loom (see fig.
2
page 8
).
3.
Feeder's Stand and Creel must be connected to the earth of the loom.
4.
Connect the plug of the 3
-
phase power cord to the socket on the loom main
control cabinet
(MCC). See fig.
2
page 8
.
Warning!
The
connection between the Voltage Supply B
ox and the 3
-
phase power supply
network must always be as stated on the follow
ing page. In this way, the loom
main switch
performs also as main switch
for the Weft Feeders (see fig.
2
page 8
).
Note:
The Voltage
values supplied to the Weft Feeders can be checked on the Voltage
Supply
Box connectors (see fig. 3
page 8
).

SETTINGS AND OPERATION
How to set working parameters
1.
Turn the loom main switch ON. The feeders are now supplied with power and
receive
the
setup data from the loom Control (wait for about one minute).
2.
The pulsar calibration cycle is then automatically performed. If no faults occur,
the signaling
led, on the front side of the feeder, remains ON. In case of faults,
the led blinks and a
fault
message is shown on
the loom Dialog panel display.
3.
According to the woven article, adjust the functioning parameters of Super Elf X3
, which
can be set on DORNIER loom Dialog panel (see picture
below).
4
.
Press the icon
to enter the feeder pages.
Note
:
Before switching the loom power ON, always
verify that the pulsar fork
(F)
is free
to move and
therefore avoid:
· Yarn tied to eyelet h
older or any other machine part
· Yarn inser
ted into
the fabric and not cut
The yarn can be kept firmly by loom controlled devices
as these are synchronized
with the Pulsar calibration
function.
T
o
reset the error
"Pulsar not calibrated",
switch the loom OFF, make
sure that the Pulsar fork is
free to move
,
th
e
n switch the
loom
back ON.
