Close monitoring for sliver breakage This is 8 beams reflection type sensor which was developed for detecting sliver breakage of drawing frame s. As the sliver is checked one by one, it is possible to check accurately. Also, it is to detect stably against up/down or right direction because of enough for detecting characteristic. |

Operation |
||||||||||||||||
|
When normal sliver |
|||||||||||||||
|
Light-entering lamp on the sensor is lighting up. Sliver breakage lamp is going off. |

|
||||||||||||||||
|
When sliver breakage |
|||||||||||||||
|
Sensor for sliver breakage become s non-light-entering state and light-entering lamp goes off and sliver breakage lamp lights up. |
|||||||||||||||
|
|
|||||||||||||||
|
Note) Sliver breakage lamp and output is self-holding circuit and is keep this state till reset or cutting power source. |
|||||||||||||||
|
Reset(Releasing holding state) |
|
Breakage lamp and output is released by "Close" between 9 & 13. |
