CX- PRECAUTIONS FOR PROPER USE Retroreflective type sensor with polarizing filters If a shiny object is covered or wrapped with a transparent film, such as those described below, the retroreflective type sensor with polarizing filters may not be able to detect it. In that case, follow the steps given below. Example of objects Can wrapped by clear film Aluminum sheet covered by plastic film Gold or silver color (glossy) label or wrapping paper Steps Tilt the sensor with respect to the object while fitting. Reduce the sensitivity. Increase the distance between the sensor and the object. Self-diagnosis function (Self-diagnosis output type only) The sensor diagnoses the incident light intensity, and if it is reduced due to dirt or dust, or beam misalignment, an output is generated. Sensing condition Sensing output (operation indicator) (in the Light-ON mode) Stability indicator Self-diagnosis output Insufficient beam intensity Insufficient beam interruption Stable light received level Sensing output threshold level Stable dark level ON (Lights up) OFF (Lights off) Lights up Lights off ON OFF Retroreflective type sensor for transparent objects Optimum is possible when the position of the transparent object is set at the center of the sensor and the reflector. If the position is set near the sensor or the reflector, the may be unstable. In this case, set the position at the center of the sensor and the reflector. Transparent object When the sensor detects an uneven plastic receptacle or glass bin, the received light intensity may differ with the position or. Adjust the sensitivity after confirming the stable condition by turning the object, etc. If the object is a transparent cylinder, feed it in a position as shown in Figure A. The sensor may fail to detect an object fed in a position as shown in Figure B. The self-diagnosis output transistor stays in the OFF state during stable. When the output changes, if the incident light intensity does not reach the stable light received level or the stable dark level, the selfdiagnosis output becomes ON. Further, the self-diagnosis output changes state when the output changes from Light to Dark state. (It is not affected by the operation mode switch.) In case of insufficient beam interruption, there will be a time lag before the self-diagnosis output turns ON.
