to simulate a light shielding state, meanwhile Green power indicator flicks;
TEST input invalid: emitter TEST input hangs in the air Or connect low level, light curtain works normally
High Level ：10~30VDC，current ＜10mA Low level：0~2VDCRNG input Distance adjustment input, when connected to a high level, it is long distance mode, and when
connected to a low level or suspended, it is short distance mode
High level:10~30VDC, current<10mA
Input low level: 0~2VDCDimensional diagram
