Switching point
Switching signals
As soon as the trigger points defined in parameters are
reached, the corresponding outputs (pins 15,16) are activated.
You can set up to two trigger points. The switching point
“zero” has a separate output (see “Zero crossover”).
Signals for sorting and tolerance checking
If the sorting limits defined in parameters are exceeded, the
corresponding outputs (pins 17, 18) are activated.
