Intercepting device: the machine surface level discharge port, and then increasing the polarity fiber identification, when the reverse polarity is detected, the machine shutdown alarm
Interceptor: paste the outlet of the machine table, and then increase the polarity recognition fiber, when the anti-polarity is detected, the machine stop alarm
Interceptor: stick flat the discharge port of the machine, and add polarity identification optical fiber. When reverse polarity is detected, the machine will stop alarming<br>
