Check whether the output OUT0 „Enable" has switched to HIGH (ready for operation),
1
otherwise there is a fault condition.
Before starting measurement, all inputs must be switched to LOW for 30 milliseconds.
2
Switch the input IN1 „Measurement Start" to HIGH.
3
Within 30 milliseconds, the outputs OUT 1-3 have switched to HIGH for the duration of the measurement
4
(system reaction time see chapter 2.2 and chapter 2.3 - depending on material and thickness).
The measurement result is available after the systems reaction time t
5
measurement starts again. An additional recovering time of 0.5 seconds is awaitet (for FE material).
The measurement result of the 2nd measurement is available at the outputs. The measurement
6
starts again.
Switch the input IN1 „Measurement Start" to LOW. The measurement is aborted, the last measurement

result is now available at the outputs OUT1-3. The measurement result is frozen until a new cycle
is initiated.
Example with „fast" PLC/BUS cycle time (smaller 20 milliseconds):
Check whether the output OUT0 „Enable" has switched to HIGH.
1
All inputs must be LOW for more then 30 milliseconds. 3 Then switch input IN1 „Measurement Start"
2
to HIGH.
Check whether all outputs OUT1-3 switch to HIGH within 30 milliseconds. 5 Continue to interrogate
4
the outputs OUT1-3, until (after the systems reaction time t
If required, interrogate several measurements.
6
Then switch input IN1 to LOW. The measurement is aborted, the last measurement result is now

available at the outputs OUT1-3. The measurement result is frozen until a new cycle is initiated.
Example with „slow" PLC/BUS cycle time (larger 20 milliseconds):
Check whether the output OUT0 „Enable" has switched to HIGH.
1
All inputs must be LOW for more then 30 milliseconds. 3 Then switch input IN1 „Measurement Start"

to HIGH.
Continue to interrogate the outputs OUT1-3 until (after the systems reaction time t

result is available.
If required interrogate several measurements.
