4.3 Connecting the Sewing Drive
ATTENTION !
All work on the electrical equipment of the special sewing
machine may only be conducted by electricians or
appropriately trained persons.
The mains plug must be pulled!
It is essential to follow the operating instructions of
the manufacturer enclosed with the sewing drive!
With all sewing drives (FIR and EFKA):
–Connect the electrical connection lead from the main switch on the sewing drive.
Sewing drive EFKA VD552/4P720V:
–Connect the set value initiator (pedal) and coupling/brake (see Illus. pg.12)
Sewing drive EFKA DC1600/DA820V:
–Connect the commutation initiator and set value initiator (pedal) (see Illus. pg.12).

5Control panel Control panel
Not identified connection jacks are not active with this machine class!
4.4 Checking the Nominal Voltage
ATTENTION !
The nominal voltage given on the identification plate and
the mains voltage must be in agreement.
An adaption to the local mains voltage occurs via the connection terminals on the
transformer of the sewing drive.
–Check the arrangement of the connections on the transformer of the sewing drive.
–If necessary, alter the connections according to the existing mains voltage (see
Wiring Diagram).
The direct current sewing drive used is operated with a "single-phase alternating
current". In order that there be no overloading of individual phases with the connection
of multiple sewing machines on a 3-phase supply, the following is to be observed:
The connections of the individual sewing machines must be spread equally over the
phases of the 3-phase supply (Wiring see Wiring Diagram).

6.3 Checking the Direction of Turn
ATTENTION !
Before commissioning the special sewing machine it is
essential to check the direction of turn of the sewing drive.
Turning on the special sewing machine with an incorrect
direction of turn can lead to damage.
The arrow in the illustration shows the correct direction of turn (counterclockwise run).
3-phase drives
The direction of turn is determined by the rotary field of the current supply.
–Insert the mains plug.
–Check the direction of turn of the motor ventilator wheel by briefly turning on the
main switch.
–With an incorrect direction of turn check if the current supply generates a clockwise
rotary field.
Is this the case, then two phases in the mains plug must be interchanged.
Direct current drives
The direction of turn is set to counterclockwise run at the factory.
If the special sewing machine was delivered in individual components, then the
direction of turn is to be checked.
The direction of turn is set at the control panel.
With counterclockwise run the parameter F-161 must be set to the value "0"
(see instructions of the motor manufacturer).
ATTENTION !
After a change in the direction of turn the positions must be
programmed again.

6.4 Checking the Positioning
Reference position
The reference position is the starting point for all positions set at the factory. In the
reference position the lowering needle point lies at the height of the top of the needle
plate.
Position 1
By sewing machines with thread trimmer the trimming sequence is initiated in the 1st
position. The trimming must occur before the needle low position because the
thread-pull knife would otherwise collide with the bobbin case opener finger.
In the 1st position the lower edge of the needle eye of the lowering needle must lie at
one level with the hook covering ring 1.
Position 2
In the 2nd position the thread lever lies in the high position.

18

Checking the positioning
–Turn the main switch on.
–Briefly step forward on the pedal.
The sewing machine positions in position 1.
Check the position of the needle.
–Step the pedal completely back and hold.
The thread is trimmed.
The sewing machine positions in position 2 (thread lever high position).
–Check if the thread lever lies at its upper dead center.
For this, turn the handwheel back and forth slightly.
–This normally completes the check.
Should a correction of the factory settings be necessary, proceed as follows for the
programming of the positions.
6.5 Setting the Positions
The synchronizor must be reset after the following work:
–Mounting of the synchronizor during installation of the special sewing machine
–Screwing off of the synchronizor
–Replacement of the synchronizor
–Replacement of the microprocessor of the dirve controls
–Replacement of the whole drive controls
No mechanical settings are necessary on the digital synchronizor.
Before commissioning only the reference position must be set.
The machine positions are registered by the synchronizor in steps (increments) and
shown in the display.
One rotation of the handwheel corresponds to 512 steps.
The change in the display occurs in steps of 2. A change from one to the next display
value thus corresponds to a rotation angle of approx. 1.4°.
The angle setting of positions 1 and 2 to the reference position is each defined by a
specific number of increments.
