Other factors that may affect the control
DELAY [s]
Is the sensor waiting time before starting the control process, namely the time needed to the machine to
reach the set speed
(Programmable).
TENS [ABS/REL]
It defines the sensor operating mode as regards the calculation of min/max threshold and peak values with
reference to the yarn tension
.
ABS:
ABSOLUTE
mode – all calculations are carried out according to a constant reference value
(TENS) defined by the operator during the article programming phase (NEW or MODIFY)
which applies to all sensors to which that article has been loaded (LOAD) .
The
TENS H
,
TENS L
,
PEAK H
,
PEAK L
and
NOYARN
values too will then be constant values with
respect to the
TENS
reference and will always remain unchanged throughout the entire yarn
processing cycle
REL:
RELATIVE
mode – All calculations are carried out according to a reference value self-learned
by each sensor during the
LEARN
phase, that will remain constant throughout the entire yarn
processing cycle. Even in this case the
TENS H
,
TENS L
,
PEAK H
,
PEAK L
and
NOYARN
values will
be constant values, but referred to a specific value ( relative ) to each sensor.
KEY [LOCK/UNLOCK]
It defines the Touch Light button operating mode:
LOCK: The button is enabled for the Automatic Numbering procedure only.
UNLOCK: The button is enabled not only for the Automatic Numbering procedure, but also for reset in
case of alarm.
MODE [MONITOR-CONTROL]
It defines the operating mode of the system when a defect is detected
MONITOR: No Failure = Green LED lit
TENS H failure = 1 flash, red LED
PEAK H failure = 2 flashes, red LED
TENS L failure = 1 flash, red + green LEDs
PEAK L failure = 2 flashes, red + green LEDs
NOYARN failure = continuous flashing, red LED + STOP output activation
In Monitor mode, as soon as the failure condition disappears, the sensor automatically
resumes the normal operation and turns on the green LED.
CONTROL: No Failure = Green LED lit
TENS H failure = 1 flash, red LED + STOP output activation
PEAK H failure = 2 flashes, red LED + STOP output activation
TENS L failure = 1 flash, red + green LEDs + STOP output activation
PEAK L failure = 2 flashes, red + green LEDs + STOP output activation
NOYARN failure = continuous flashing, red LED + STOP output activation
In Control mode, the failure condition must be reset either through the touch light or through
the ENABLE input (see Note on next page).
