Activating input delay
(debounce) Input signals are evaluated by the display system with an input
delay. This enables, for example, the trouble-free evaluation of
switches and pushbutton actuators subject to contact bounce.
In many applications, however, very short input signals have
to be monitored. In this case, the debounce function can be
switched off.
