tecting device]
1) Connect solenoid valve cable
❽
of the air blower
solenoid valve_SD to the CN4.
2) Connect the 16P connector of the junction cable
❶
of the bobbin-thread remaining amount detect-
ing device and stitch skipping detecting device to
the CN1.
3) Connect encoder junction cable asm.
❷
to the
CN3.
4) Connect encoder extension cable asm.
❼
to the
CN2.
5) Connect the stitch skipping detecting device ca-
ble
❾
to the CN8. Put the excess of the cable in
the control box.
6) After the completion of connection of all connec-
tors, close cover
with screw
.
The connectors cannot be connected un
-
less the correct order is followed.
[Wiring of the electrical box (CTL PCB)]
Connect the connectors in the following order refer-
ring to Figs. 1 and 3.
Connect the connectors in the following order refer-
ring to Figs. 1 and 4.
1) Connect the 22P connector of the junction cable
❶
of bobbin-thread remaining amount detecting
device and stitch skipping detecting device to the
CN51.
2) Pull out the connector (motor encoder connector
coming from the sewing machine) from the CN30.
Connect encoder extension cable
