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.

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.
-Always use proper spare parts and accessories supplied by Roj s.r.l.

1. GENERAL INFORMATION
Super Elf S3 description
SUPER ELF S3 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 Reflective type
optical sensors guarantee robustness and 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 the 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.

Reaction time: 7 ms
Max torque: 11.5 Ncm
Weft pull back length: max 35 mm

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 (Reflective system).
o Storage detection with an integrated photocell (Reflective system).
o Robust and reliable new Reflective sensors system.
o Input Weft breakage control through a photocell integrated in the Super Elf S3, or through
external TFE8 weft Stop Motion device.
o Weft length adjustment, by setting the spool body diameter and the number of coils to be
released 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 means 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.

2. SETTING AND CONTROL ELEMENTS
Front Control elements
1 FUNCTION BUTTON
It activates the Electromagnet and allows the following operations:
a- Weft reserve removal.
b- New weft reserve loading.
c- Release of only one coil when the weft reserve is already on the Spool Body.
d- Photocells calibration
e- Reset of the fatal errors without switching OFF the main power.
A SIGNALING LED
When the weft feeder is powered, the led turns on if no faults are detected. In case of
problems, the led blinks. Slow blinking in case of warnings, fast blinking in case of fatal errors.
B ADJUSTMENT SCREWS FOR THE ELECTROMAGNET

Back panel control elements
1 CONNECTION OF AIR LINE INPUT
2 CONNECTION OF AIR LINE FOR FULL AIR THREADING
Full air threading is possible only in combination with Funnel. If the feeder is fitted with eyelet
holder, or without any balloon control, this connection must be closed with relevant plug that it
is supplied with the feeder.
3 HALF THREADING BUTTON
Insert the yarn into the eyelet and press the half threading button (3), whilst lightly holding the
yarn.
4 FULL THREADING BUTTON
Insert the yarn into the eyelet and press the full threading button (4), whilst lightly holding the
yarn.

3. 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 nozzles.
3. Place the Feeders' cables and the air tubes inside the tunnel of the Stand.
Electrical 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 Box and the 3-phase power supply
network must always be as stated on the following 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).

4. 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 S3, 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 holder or any other machine part
· Yarn inserted 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. To reset the error "Pulsar not calibrated",
switch the loom OFF, make sure that the Pulsar fork is
free to move, then switch the loom back ON.
