Learning Cycle
(LEARN)
!
During the Learning cycle (Learn) the system “detects” and stores the number of sensors (nnn) with
yarn running.
"
At the end of the Learning cycle, the system automatically activates the Control phase and continuously
check that the yarn runs regularly inside all the nnn sensors stored during the Learn phase. The nnn
number is shown on the Control screen.
#
Both Learn and Control phases start after a programmable delay time (Delay Control) in order to allow
the machine reaching the rated speed.
$%
To avoid evaluation mistakes (i.e. to consider a yarn running, while it is actually still), the Learn phase
uses a special BTSR algorithm that makes such phase extremely accurate.
&%
In case of unstable sensor reading, an error message is displayed.
In this case, prior to repeat the Learn operation, it is advisable to check, and possibly change, the
detection sensor parameters, in particular the sensitivity.
