must be placed in front of the sensor.
Switch the input IN2 „Teach-In" to HIGH.
3
Within 30 milliseconds the outputs OUT1-3 have switched to LOW.
4

switch to HIGH.
Example:
Check whether the output OUT0 „Enable" has switched to HIGH.
1
One sheet must be in front of the sensor. All inputs must be LOW for more than 30 milliseconds.
2
Switch input IN2 to HIGH. 4 After 30 milliseconds check whether outputs 1-3 have switched to LOW.
3
Switch input IN2 „Teach-In" to LOW.
