a) Start situation:
Limit comparator „OFF“, as actual value x not in the
switch-on range (grey area).
b) Situation at the time of the setpoint value change:
Limit comparator remains „OFF“, although the actual
value is now in the switch-on range.
c) Actual value has left the switch-on range:
Limit comparator operates according to its function
again, which means it remains „OFF“ until the actual
value has reached the switch-on range again.
