btsr SMART MATRIX TWIST Operating Manual page 77

Mode
It defines the operating mode of the system when a defect is detected:
MONITOR: Signals the error by means of a single or double flash of the red Led, without activating the
Stop output.
CONTROL: Activates the Stop output and signals the error by means of a single or double flash of the red
Led.
1 red flash
2 red flashes
The sensor keeps active the STOP output and the error signalling until the failure is reset
(either manually using the touch light or automatically, depending on Reset parameter setting).
D.filter
The IS3.. sensor features an internal digital filter to reduce the influence of natural yarn hairiness in the
twisting evaluation process (TPX).
(It can be programmed with a value ranging from 1 [no influence] to 8 [max efficiency])
Stop Out
(NO, NC)
Stop Mode
(CONT, PULSE 2S, PULSE 10S)
Characteristics of the Stop output: see the following examples.
Examples:
CONT
PULSE 2S
PULSE 10S
Normal Operation =
Delay Control =
Failure Reset=
Note: When the sensor is de-activated, the STOP Output is always in Normal Operation condition
therefore, in case of NO configuration it will always be an open circuit.
= TPX-L (No twisting insufficient)
= TPX-H (No twisting excessive)
Failure
Failure
2 seconds
Failure
10 seconds
(the yarn runs normally and the number of twisting is within the
programmed range TPX MAX and TPX MIN)
Delay programmable via software
Either Manual through (Touch Light) or Automatic if Reset Manual/Auto
