Overlapping of blocking zones
If blocking zones overlap, the lowest and highest value of the overlapping zones form a new zone.
In this case, the status display (wState output) will also just display one zone (the lower one of the

two original zones).

Abutting blocking zones
If two blocking zones abut (e.g. 20 ... 30 % and 30 ... 40 %), the limit value between the two zones (in

this example 30 %) is also passed through.
The same applies to a limit range of 0 ... xx %. At the zero crossing of the nIn_a input signal, a value

of "0" is also output at the nOut_a output. Value "0" cannot be excluded. If the nIn_a input signal

drops back to "0", the nOut_a output will retain the upper limit value.
