WARNING!

• The power supply must be switched off at the mains
before any work is carried out on the feeder, the trans­former/interface or any other electrical components.
The feeder and the transformer cabinet and cable cov­ers must be fully assembled before the power supply is
connected.

• The weft feeder ON/OFF-switch DO NOT cut off the main
power supply. Turn off the main switch before any work
is carried out on the electrical circuit.

• The feeder and transformer contain electrical compo­nents that retain an electric current up to three minutes
after disconnection. DO NOT open or disconnect feeder
or interface, including cables, within this time.

• All work on electrical components must be carried out

by a qualied electrician.

To set the maximum speed rotate the disc to the appropriate position.

NOTE

Normally the switch should be left at posistion 1 since the feeder automatically calculates the speed according to yarn
consumption. However, with very low speeds or wide looms, it could be helpful to reduce the maximum speed in order
to avoid unnecessary acceleration

Switch off the feeder.

On feeders with S-ex, the S-ex must be detached for

making the S/Z adjustment.
See page 31-32 (Flex-brake mounting).

Grip the winding disc and, whilst pressing the orange
button on the front of the spool body, rotate the disc
until the button is felt to locate. Aligning the mark on the
winding disc with the line on the motor house gives the
zero separation position.

To adjust, press in the button and revolve the winding disc
in the appropriate direction. The separation increases from
0 to 4 mm the more the disc is rotated.

The separation must be distinct, but not excessive.

Set the direction of rotation with the switch. (The feeder is
deactivated in the standby position (0))

NOTE

On feeders with brush, choose the correct type of
brush (S, Z or Straight) depending on the direction
of the rotation. See page: 32

The mechanical sensors are placed on the xed part of

the spool body.

The sensor (1) controls MAX reserve level, and the sen­sor (2) controls MIN reserve level.

The force needed to press down the sensors is control­led by a spring, and it is adjustable with screw (3). Turn
the screw (3) anti-clockwise to increase the sensor
strength, turn it clockwise to reduce it.

AUTOMATIC CALIBRATION OF THE SENSORS

NOTE

Before starting the automatic sensors calibration,
check the following:

• Remove all yarn from the feeder

• The spool body must be in correct position.

• The sensors must be free to correctly move up and
down.

• The sensors ring must be correctly xed.

1. Switch OFF the feeder.

2. Disable the TFE9 by moving the switch (4) up­wards. The LED of TFE9 must be steady-ON in
red color.(5)

3. Switch ON the feeder and let it turn without weft for
at least 50 revolutions, until the winding disk stops.
(feeder red light steady ON).

4. Switch OFF the feeder, and enable the TFE9 by
moving the switch down

5. Thread the yarn through the feeder (see page 15)

6. Switch ON the feeder and load a new weft reserve.

LED (5)
When disabled, the LED (5) is steady RED ON.
When enabled, the LED (4) is GREEN only when the
yarn is creating signal, otherwise it is OFF.

When using a brush it is possible to use the whole setting
area of the brush holder ring.

FLEX

When using a ex it is important to keep the settings in the

center of the setting area, to ensure proper tension and

longer life time of the ex. Avoid to set the brush ring in the

outer areas.

BALLOON CONTROL

Balloon control adjustment.

NOTE

Excessive brush tension will cause abnormal wear.
