IS3x/TTS Sensor Features
SMART MATRIX TWIST - 3-6 -
Touch Light Function
Failure Reset : When the sensor is in Failure Status (Red Led blinking) by skimming the touch light you
reset the failure and, after the programmed Delay-Control time, the sensor resumes the
control.
Numbering : When the sensor is in Numbering Status (Green Led blinking) , by skimming the touch
light, you give the sensor the identification number shown in
Config
→
Identify .
Activation/
De-Activation
: When the sensor is either in Control or Delay-Control phase, by skimming the touch
light you will either deactivate or re-activate the sensor itself.
This function can be either enabled or disabled using parameter LOCK-UNLOCK.
Sensor –System Interface
The sensor communicates with the SM-DIN TWIST Board and with the textile machine through the following
signals:
TX-RX: Is the bi-directional communication line between sensor and SM-DIN TWIST Board, used for
sensor operation parameters programming, for sensor’s test and for all the other real-time
communications between sensor and Board.
STOP Output: The STOP signal is an OPEN COLLECTOR Output through which the IS3x/TTS sensor
signals the yarn control status (number of twisting within the minimum-maximum
programmed range or number of twisting higher than the maximum threshold or lower than
the minimum threshold)
.
The STOP Output can be configured as a Normally Open (NO) or Normally Closed (NC)
signal and, in addition, it can be configured either as Continuous signal (CONT) or as a 2
seconds Pulse signal (PULSE 2S) or 10 seconds Pulse signal (PULSE 10S) .
