  1. 송신기 활성화시 결합된 수신기가 응답하는 지를 제1채널에서 체크하고 활성화 되지 않는 송신기에 대해 결합된 수신기가 응답하는지를 제2채널에서 체크하는 평가회로를 갖추고 송신기/수신기 쌍을 활성화하는 제어회로를 갖추고, 이들 회로와 개별적으로 결합된 여러개의 (광) 송신기 및 (광) 수신기를 갖춘 광 배리어로써,
    제3채널이 공급되어 수신기의 출력신호중 다이내믹 부분에 응답하고 장애 발생시 제1 및 제2채널의 응답감도를 증가시키는 것을 특징으로 하는 광 배리어.
  2. 제1항에 있어서, 평가회로가 주기적으로 및 교대로 측정 및 테스트를 하므로써, 송신기와 수신기가 측정동안에 활성화되는 반면에, 테스트 동안에 송신기가 비활성화되고 수신기가 활성화됨을 특징으로 하는 광 배리어.
  3. 제1항 또는 제2항에 있어서, 광 배리어에 의해 제어된 장치 또는 기계의 개개의 부품(예를들어, 모우터보호, 계전기)이 평가회로 내에서 기능적으로 합동됨을 특징으로 하는 광 배리어.
