7. Connection to the electrical mains supply and checking the direction of
rotation
Work on the electrical components of this
sewing unit should only be conducted by
authorized personnel and with the mains
plug pulled.
The mains voltage and the nominal voltage
(operating voltage) must be identical.
The plate specifying the nominal voltage can be
found at the front on the spar under the table top.
Before starting the unit observe the specified
nominal voltage!
For operation with other mains voltages the
information in the enclosed construction circuit
diagram 9870 744001 B is to be noted and the
appropriate connection alterations made.
Also see 1.2 Technical Specification.
Danger of breakage due to wrong direction
of rotation!
It is essential that the direction of rotation be
checked before operation as follows:
–
Move the machine head out of its upper needle
position by turning the handwheel.
–
Insert plug into mains socket.
–
Switch on main switch while observing the
handwheel.
–
The handwheel must move in the indicated
machine rotation direction to the 2nd needle
position (needle high position).
By wrong needle position see Section 6 of the
Service instructions.
8. Starting operation
After each switching on of the main switch the
display <-----> appears.
After operating the key on the control unit a
reference run is made which defines the exact
initial position of the transport carriage.
Then the display shows the last program status
entered into the control unit.
Switching the individual steps of the feed
procedure and the sewing start occurs by tapping
the pedal.
When starting sewing material must lie under the
material guide rail.
Transport without material damages the coating of
the material guide rail.
Sewing program and feed procedure are to be set
according to work procedure used.
See the enclosed operating card and Section 4.5 of
the Microcontrol summary in the annex to the
instructions.
