8. Connecting the electric elements on the
machine head
The connection of the electric elements (electromagnets,
backtacking, presser foot lifting, thread trimming, loosening
of the tensioner and push-buttons) is made by means of a
switchboard (1) fixed with its supporting plate (2) on the rear
side of the head by means of two distance screws (3) (In the
Fig., these electric elements are disconnected).
Connecting spots :
4 - backtacking electromagnet
5 - trimming electromagnet
6 - tensioner loosening electromagnet
7 - presser foot lifting electromagnet
8 - connector of push-button connecting
9 - connector of coupling the head with the stopmotor
10 - connecting cable of the head and stopmotor

machine head.
9. Drive, control panel, position sensor
For machines provided with an oblique trimming device and
with the EFKA stop motor DA82GA, 6F82FA and DA320, the
connector outlet A28 (used for needle cooling as a standard)
for controlling the trimming device motor is being used, which
is being switched on only when sewing. After having ended
the sewing operation, it is switched off with an adjustable
delay of 0-5 s (parameter 183).
The detailed information concerning the drive, the control
panel and the setting of the position sensor is given in the
manual of the drive and of the control panel.
10. Lighting
10.1 Mounting on the machine head
Caution! Danger of injury!
Switch off the main switch! Before starting the
setting operation, wait until the motor stops!
- Mount the lamp on the machine head using the screws (3).
- The lighting (5) conductor is to be led through the guard (1)
into the channel of the head on its rear side.
10.2 Lamp replacement
Caution! Danger of injury!
Switch off the main switch! Before starting the
setting operation, wait until the motor stops!
- Remove the guard (1) by unscrewing the screw (2).
- Remove the lamp from the machine head by unscrewing two
screws (3).
- Shift the glass (4).
- Loosen two screws of the lamp holder.
- Replace the lamp.
Use only 12 V, 10 W lamps. With higher values of
the lamp power, there is a danger of overheating.
