Hook thread monitoring
Hook thread monitoring mode of operation:
Hook thread monitoring is carried out by counting the buttonholes.
With the insertion of a full bobbin the hook thread counter is set to a
predetermined value. This value is subtracted by one with each
complete cycle. When the value 0 is reached the operator receives an
information message.
There should be some remaining thread on the bobbin.
Note
This principle only functions when the same amount of bobbin
thread is used per buttonhole or sequence. Changing frequently the
cut length, buttonhole form or buttonhole parameter changes the
amount of bobbin thread used per buttonhole.
