(interval distance : min. 0.3m) transmission direction should be opposite between 2 sets it may cause interference when installing more than 2 sets of the sensor. in order to avoid the interference of the sensor, please install as following figures and use the interference protection function. it should be installed out of the interference distance malfunction cause troubleshooting non-operation power supply supply rated power. cable incorrect connection or disconnection check the wiring. rated connection failure use it within rated sensing distance. non-operation in sometimes pollution by dirt of sensor cover remove dirt by soft brush or cloth. connector connection failure check the assembled part of the connector. control output is off even though there is not a target object. out of rated sensing distance use within rated sensing distance. there is an obstacle to cut off the light emitted between emitter and receiver remove the obstacle. there is a strong electric wave or noise generated by motor, electric generator, high voltage line etc. put away the strong electric wave or noise generator. led displays for synchronous line malfunction synchronous line incorrect connection or disconnection check the wiring. break of synchronous circuit of emitter or receiver contact our company. led displays for over current control output line is shorten check the wiring. over load check the rated load capacity.
