20 / 38 page  E3X-NH E3X-NH 20 Threshold Setting and Indicators at Sensitivity Setting Threshold indicators Level 1 2 3 4 5 6 7 8 9 10 11 12 13 Maximum Sensitivity Setting • Use the Through-beam Sensor for detection of opaque objects. • Use the Reflective Sensor for detection of objects with no background objects. The threshold will be set to a level slightly higher than the no-light received by the E3X-NH if the sensitivity is set to maximum for the detection of objects that completely interrupt light or the incident of the Sensor is very low. Reflective Sensor The number of lit indicators of the incident level indicators will depend on the incident. The bottom indicator of the threshold indica- tors is ON. Large Small Light Sensing object Threshold Incident level indicator Threshold indicator Sensing object With/Without-object Teaching • Ideal for the detection of object surface irregularities or minute objects. • Ideal for the detection of objects with background objects reflecting light irregularly. 1. With/Without-object Teaching Reflective Sensor: Small Light Fiber head Sensing object Large Press the SET button with the sensing object in the sensing area. Set the threshold to the middle value between the values obtained with and without the sensing object. Small Light Fiber head Large Press the SET button with- out sensing object in the sensing area. Small Light Large Threshold 2. RUN/ADJ Mode Reflective Sensor: The number of lit indicators of the incident level indicators de- pends on the incident. At the time of manual-tuning, it is pos- sible to adjust the threshold in six levels. The default thresh- old is set to 7.
