5. Electrical connection

The machine drive is supplied from the low voltage network.

Caution!

All work on the electrical equipment of this special sewing
machine may only be carried out by qualified electricians or
other appropriately trained persons.

The mains plug must be removed.

5.1 Electric connection of machine to low voltage network

According to the selected type the machine drive has a one-phase or
three-phase supply. If the drive has the three-phase supply, it has an
asynchronous motor. In that case it is necessary to adjust the
connection of the coils in the motor terminal board (star or triangle) to
the voltage of the local electric network.

Caution!

The mains voltage must agree with the rated voltage specified
on the model-identification plate.

The low voltage circuit includes the following items:
–

Supply plug

–

Main switch (with the drive on the machine head the main switch is
incorporated in the drive)

–

Drive

–

Sewing lamp transformer (option)

–

Cables

Part of these items is included in the drive package. The other part is
included in the package of the set of parts for motor obligatorily
supplied with the machine head. The division of the items can be seen
in the catalog of spare parts. The low voltage circuit connection will be
made according to the wiring schedule, which is included in the
package of the set of parts for motor.

Caution! Risk of electric current injury!

The drives may be operated only with a safety conductor connected
to the functional protective system in accordance with the regulations
and rules to avoid personal injuries by electric current or fire.

The drive operation will become dangerous if the safety conductor
inside or outside the drive is disrupted. The protection must not be
disrupted with e. g. an extension cord without the protective conductor.

6. Setting of positioning motor (drive)

The function of the positioning motor (drive) is defined by its program,
drive parameter setting, and the machine stopping positions. If the
machine is supplied in the disassembled condition, the drive setting
must be carried out by the purchaser. If the sewing machine is supplied
in assembled condition, the drive is already set by the sewing machine
manufacturer.

6.1 Setting of positioning motor (drive) parameters

The setting of the drive parameters is carried out in two steps. In the
first step, the parameters for the family of sewing machine class
groups are set by the function “autoselect“. In the second step, some
of the set parameters are changed to match the particular class.

6.1.1 Autoselect

The drive control system is equipped with the “autoselect“ device,
which is able to identify what sort of the sewing machine was
connected to the drive (with a connection cable). At the drive switching
on, the value of the resistance of the resistor located inside the sewing
machine head for this purpose is measured automatically. As a result
of this, the required parameter values are set automatically. If the
control system is not able to identify the valid resistance, the drive
control will run with so-called safety operation functions only to avoid
the sewing machine damage.

6.1.2 Setting of parameters

Caution!

Change of the parameter value must be performed with consideration
and in a responsible way. A false setting of the control may cause the
machine damage!

Warning!

By the so-called master-reset (see chapter 6.3) it is possible to
reset all parameter values back to the preset values again.

Parameter selection and value change:
–

By the keys “+” and “-” the following or previous parameter is
selected.

–

By the keys "+" and “-” it is possible to enter the parameter number
directly.

–

Press the key “E”. The value of the selected parameter is
displayed.

–

By the keys “+” and “-” the parameter value is changed.

–

Press the key “E”. The value of the following parameter is
displayed, or
press the key “P” - the same parameter is displayed.

The 1A and 2A positions are important only for the internal functions of
the DA82GA and DA321G controls.

6.2.2 Setting the machine positioning for DC1600/DA82GA motor drive and DC1550/DA321G

For the needle and other elements positioning the incremental sensor
located on the hand wheel is applied which gives 512 impulses
(increments) and one additional impulse per rotation. In general, the
particular position is defined by the number of increments between this
position and the reference position. The increment number is set by
the corresponding parameter value (it is not, however, identical with
the parameter value). The position parameter values have already
been set - see chapter 6.1.3.1. The reference position still remains to
be set.

The reference position is defined by the angle 105° on the hand wheel
scale.

After dismantling, mounting, or replacement of the synchronizer a new
reference position must be set.

See the “Efka DA82GA” or “Efka DA321G” operating manual.

6.2.4 Setting of machine positioning with VD552/6F82FA drive

The synchronizer contains one internal disc with increments
(generator) for the speed regulation, one central adjustable
diaphragm (1) to set the 1st needle position, and one marginal
adjustable diaphragm (2) to set the 2nd needle position.

Caution!

At the position setting it is necessary to proceed with extreme caution!
Danger of injury!

At handling be sure that the diaphragms and generator disc are not
damaged.

Caution!

At the setting of the positioning diaphragms the network switch must
be switched off unconditionally!

–

The direction of the drive rotation is already set c orrectly.

–

After loosening the screw remove the speed sensor cover.

–

By the key S5 (on the control box) select the needle lower position
(LED 7 illuminates).

–

Tread the pedal forwards shortly.

–

Check the 1st position of the needle.

–

If the needle is not in the 1st position, the central diaphragm for the
1st position (with the main switch switched off) must be turned in
the required direction.

–

Repeat the procedure until the 1st position is set correctly.

–

Switch on the network switch.

–

By the key S5 (on the control box) select the needle upper position
(LED 8 illuminates).

–

Tread the pedal forwards shortly.

–

Check the 2nd position of the needle.

–

If the needle is not in the 2nd position, the marginal diaphragm for
the 2nd position (with the main switch switched off) must be turned
in the required direction.

–

Repeat the procedure until the 2nd position is set correctly.

–

Put the speed sensor cover back again and screw.

6.2.5 Checking of set positions

6.3 Master reset

1st position

–

Switch on the network switch.

–

Tread the pedal forwards shortly and release. The machine is
stopped in the 1

–

Check the angle on the hand wheel scale (225° ± 5°).

2nd position

–

Tread the pedal forwards shortly at first and then entirely
backwards with the heel until the machine stops. The machine
stops in the 2

–

Check the angle on the hand wheel scale (55° ± 5° or 35° ± 5°).

By means of the so-called master-reset all changed values are set
back to the preset ones again.

7. Lubrication

8. Sewing test

Before start, the machine must be lubricated properly with oil
according to chapter 11.2 in the first part (operating instructions).

This test can be carried out only after the machine is set completely.
–

Thread in the bobbin-winder thread (see operating instructions).

–

Turn on the main switch.

–

Lock the sewing foot in the lifted position (see operating
instructions).

–

Fill the bobbin at low speed.

–

Turn off the main switch.

–

Thread in needle thread and bobbin thread (see operating
instructions).

–

Select the material to be sewn.

–

Carry out the sewing test first at low speed and then gradually
increase the speed.

–

Check whether the seams are of the desired quality.

–

If the quality requirements are not met change the thread tensions
(see operating instructions).
