3.4 Attaching the Yarn Stand
The yarn stand is enclosed loose.
For a mains connection from above, the connection cable can be
drawn through the tube 2 of the yarn stand.
The compressed air feed can be guided up through the 2nd drilled hole
in the table top and attached to the yarn stand with cable clamps.
–Insert tube 2 and screw the nut 4 fast under the work plate.
–Align the yarn spool holder 1 and take-off arms 3 parallel to the
rear edge of the table. The yarn spool holder 1 and take-off arms 3
must lie above one another.
3.5 Checking the V-belt Tension
It must be possible to press the V-belt 2 together approx. 10 mm at the
center.
Setting the V-belt tension
–Loosen screw 1.
–The drive 3 is swung until the desired V-belt tension is achieved.
–Tighten screw 1 again.

4. Electrical Connection
ATTENTION !
All work on the electrical equipment of the sewing unit may only be
conducted by electricians or appropriately instructed persons.
The mains plug must be pulled.
4.1 Connecting the Microcontrol Control Unit
–Place the control unit on the mounting plate and fasten with the
stopper nuts.
–Connecting the cables:
Attention!
Carfully insert the plugs into the control unit back plate.
In as far as these exist, observe corresponding designations on
the cables and back plate.
Also observe the differing outfitting of the plugs with contact pins
or contact sockets, as well as their number and arrangement.
–Tighten the screws of the plugs.
4.2 Checking the Nominal Voltage
The nominal voltage listed on the identification plate and the mains
voltage must correspond !
For conversion to another mains voltage the appropriate parts set
must be mounted.
The parts set consists of:
Belt pulley, V-belt, protection switch insert.
Nominal voltage: Order no.:
3 ~ 380 - 415 V + N , 50 Hz 9880 743002
3 ~ 220 - 240 V , 50 Hz 9880 743003
3 ~ 220 - 240 V , 60 Hz 9880 743004
When converting to another mains voltage the wiring must be
changed. The wiring is to be found in the wiring diagram.
The bridges in the motor terminal box are to be switched in " Star " or
" Delta " appropriate to the mains voltage !

4.3 Setting the Motor Protection Switch
The motor protection switch 1 must be set appropriate to the mains
voltage.
220 - 230 V 4.2 A
380 - 400 V 2.5 A
4.4 Checking the Direction of Rotation of the Motor
ATTENTION !
Before commissioning the sewing unit it is essential that the direction
of rotation of the motor be checked.
Turning on the sewing unit with an incorrect direction of rotation can
lead to damage to the unit.
–The correct direction of rotation of the handwheel is shown by the
arrow on the handwheel belt guard 1.
–If the direction of rotation is not correct, then it must be checked if
the power supply generates a clockwise rotary field.
If this is the case, then 2 phases in the connection plug must be
interchanged.

4.5 Checking the Positioning
The sewing unit should position when the handwheel is in position
between Band C.
Checking the positioning
–Turn the sewing unit off.
–By turning the handwheel, bring the thread lever into a middle
position.
–Turn the sewing unit on.
The sewing unit positions.
Setting the position
–Loosen the set screws of the synchronizer.
–Hold the synchronizer collar 1 fast.
–Turning the handwheel in position between Band C.
–Check the positioning again.

5. Pneumatic Connection
ATTENTION !
For a fault-free functioning of the pneumatic control sequences, the
following notes are to be observed.
The compressed air supply must be so conceived that even at the
moment of the greatest air consumption a minimum operating pressure
of 5 bar is not fallen short of.
The connection to the compressed air supply is made with the
accessories available as optional equipment ( 0797 003031 ) or with
in-house connection material.
Operating pressure 2 = 6 bar
The blower pressure 1 must be suitable for the material.
Standard setting: approx. 3 bar
To set the pressure, lift and turn the appropriate knob.
Turn to the left = Decrease pressure
Turn to the right = Increase pressure
