Universal L-Print (power)
The power PCB (L-Print) is installed in the cover at
the back of the sewing machine.
The circuit components of the L-Print producethe
following direct current voltages:
5 V/DC for the logics on the S-Print
12 V/DC for the sewing light
30 V/DC for the main motor, winder
motor and stepping motors
16 V/DC for the motor control on the
S-Print
In the event of malfunction, the F2 (T-3, 15A
secondary) /F3 (F-4A primary) fuses protect
components against overload. If a fuse blows, this is
always for a reason. The cause must be identified
and removed. An original replacement fuse of the
correct rating must be used. It is essential to test the
functions on replacing the fuse.
The L-Print and S-Print are connected via an 8-pin
ribbon cable.
Fuse F 2 T- 3,15 A Item no. 031 999.50.00
Fuse F 3 F- 4 A Item no. 031 999.50.01
S-Print
The S-Print is manufactured according to S.M.D. (Surface Mounted Device)
technology.
S.M.D. components facilitate very compact circuitry.
S.M.D. printed circuits cannot be repaired with conventional tools!
The sewing computer data is saved on an
EEPROM on the S-Print.
If the S-Print needs to be replaced, that EEPROM
must be moved to the new S-Print.
EEPROM markings must match.
