5.16 Thread database
All threads you wish the machine to sew with must be recorded and
defined in the thread database.
Fig. 170: Thread database
The thread database allows you to
• create a new needle and/or hook thread,
• change a needle and/or hook thread,
• delete a needle and/or hook thread
5.16.1 Creating a new thread
To create a new needle or hook thread, you must re-assign the ident.
number of the new thread. Every
thread has been assigned a so-called ident. number by the manufacturer.
The ident. number is included on every needle or hook thread reel.
You can, for instance, specify that you wish to read the first 4 digits of
the ident. number ( p. 159). The manufacturer may include such infor-
mation in the first 4 digits as the type or the color of the thread.
The ident. number is stored in the seam record set. A check at the begin-
ning of the sewing process will determine if the needle and hook threads
on the machine match the selected seam record set. If the threads match
the seam record set, the sewing process can be started. If not, an error
message will be displayed, and the sewing process cannot be started.
