Check whether the output OUT0 „Enable" has switched to HIGH (ready for operation),
1
otherwise there is a fault condition.
Before starting a measurement, all inputs must be LOW for 30 milliseconds.
2
Switch the input IN1 „Measurement Start" to HIGH.
3
After 30 milliseconds the outputs OUT 1-3 have switched to HIGH for the duration of the measurement
4
(system reaction time see chapters 2.2 and 2.3 - depending on material and thickness).
After point 4 or 30 milliseconds after point 3 switch the input IN1 „Measurement Start" to LOW.
5
The measurement result is available (after the system reaction time t
6
frozen until the new action 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.
2
After that switch input IN1 „Measurement Start" to HIGH.
3
Check whether all outputs OUT1-3 switch to HIGH within 30 milliseconds. 5 After that, switch input IN1
4
to LOW.
Continue to interrogate the outputs OUT1-3, until (after system reaction time t
6
is available.
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.
2
After that, switch input IN1 „Measurement Start" to HIGH.
3
After more than 30 milliseconds switch input IN1 „Measurement Start" to LOW.
5
Continue to interrogate the outputs OUT1-3, until (after system reaction time t
6
is available.
