Roller presser lifting with the knee lever

–

The roller presser is lifted by pressing the lever 3; the roller presser
is lowered at the lever release.

Caution!

At the roller presser lifting higher than 6 mm over the throat plate the
machine may not operate, otherwise the needle bar with the needle
holder hits the roller presser, or the needle guides of the double
needle machines.

Roller presser lifting with a pedal - automatically

–

The roller presser lifting in the machines equipped with a
positioning motor (drive) can be controlled by the pedal 4 treading
in the position -1 (see chapter 6.16.1). The roller presser is lifted
to the upper dead point by means of an integrated electric
magnet. After the pedal is released, the roller presser is lowered.

–

It is possible to pre-select the automatic roller presser lifting at
each machine stop without the necessity to tread the pedal in the
position to the position -1.
In this case, the roller presser is lowered at the pedal treading in
the position +1. After the finishing of the seam, the roller presser
remains lifted permanently (see chapter 8).

–

The required sewing-foot (roller) pressure is set with the setting
wheel 1.

–

To increase the roller pressure = turn the setting wheel 1

clockwise.

To decrease the roller pressure = turn the setting wheel 1

anti-clockwise.

–

The roller pressure is to be as small as possible, but strong
enough so that the roller presser is not lifted by the needle friction
in the material during the upward movement and that the feeding
is reliable.

–

The maximum roller presser pressure is 100 N.

In the machines equipped w ith the positioning motor it is possible
to pre-select the backtacking by a pre-selected backstitches
number both at the beginning and at the seam end. At the seam
beginning (after the preceding thread trimming) after the pedal
treading forwards the machine sews the pre-selected bartack
entirely automatically. The same at the seam end after the pedal
treading in the position –2 the machine sews the pre-selected end
bartack and then trims the threads (see chapter 8).

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:

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 motor part set obligatorily supplied
with the machine head. The division of the items can be seen in the
parts list.

The low voltage circuit connection will be made according to the
wiring diagram, which is included in the package of the motor part set.

Danger! Risk of injury!

The control unit is intended to be connected to an earthed alternating
current network only.

It must only be connected using a multi-pin plug with a protective
contact.

6 Adjustment of Efka positioning motor (drive)

The function of the positioning motor (drive) is defined by its program,
drive parameter setting, and the machine stopping positions. If t he
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 be adjusted to the particular
class.

6.1.1 Setting of parameters by the “autoselect” function

The drive control system is equipped with the “autoselect“ device,
which is able to identify what sort of t he 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 Efka drive parameters specific for class 884

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.

For a detailed description of the various parameters of the control
unit, please consult the enclosed current issue of the instructions of
the motor manufacturer (see also www.efka.net).

19

6.1.3 Values of parameters specific for this class 884

Parameter change for machines with gear rate of 28/28 teeth

Parameter Original value New value Parameter description

290* 0 3 Class of the machine

111 - - Max. sewing speed

* The parameter must be entered first.

Attention: to set up parameters higher as 200, it is necessary to enter
the control with a programmer’s level (via code 3112).

6.2 Setting of machine positioning

6.2.1 Position definition

Position 1

The needle is down at the stopping in the seam. The angle 225° is on
the hand wheel scale.

Position 2

The needle is up after trimming. The angle 35° is on the hand wheel
scale.

6.2.2 Setting the machine positioning for DC1550/DA321G drive

For the needle and other elements positioning the incremental sensor
located on the hand wheel is applied which gives 512 impulses
(increments) /value in ° is displayed on the display/ and one additional
impulse per rotation. In general, the particular position is defined by
the angle between this position and the reference position. The angle
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. The reference position s till
remain s to b e set.

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

After dismantling, mounting, or replacement of the motor drive the
reference position must be set again.

A reference position setting is described in the operating manual of
the motor manufacturer Efka.

20

6.2.3 Checking of set positions

6.3 Master reset

Position 1

–

Switch on the network switch.

–

Tread the pedal forwards shortly and release. The machine is
stopped in the position 1 (see 6.2.1).

–

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

Position 2

–

Tread the pedal forwards shortly at first and then entirely
backwards with the heel until the machine stops. The machine
stops in the position 2 (see 6.2.1).

–

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

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

How to proceed with the master reset is described in the instructions
of the motor manufacturer Efka.
