Communication with the PLC
Check whether the output OUT0 "Enable" has been switched to HIGH (ready for operation), otherwise there is a fault
condition.
Before initiating the Teach-in all inputs must be switched to LOW for 30 milliseconds. One sheet of nominal thickness
must be placed in front of the sensor.
Switch the input IN1 "teach-in" to HIGH.
Within 30 milliseconds the outputs OUT1-3 are switched to HIGH.
After point 4 or 30 milliseconds after point 3 switch the input IN1 "teach-in" to LOW.
Now the unit performs a "teach-in" procedure. The teach-in is completed within 7s and the outputs OUT1-3 switch to
LOW.
Example:
Check whether the output OUT0 "Enable" has been switched to HIGH.
One sheet should be in front of the sensor. All inputs should be on LOW for more than 30 milliseconds.
Now switch input IN1 to HIGH.
After 30 milliseconds check whether outputs 1-3 have been switched to HIGH.
Now switch input IN1 "teach-in" to LOW.
After >7 seconds check whether the outputs OUT1-3 have been switched to LOW.
