3.2.4.2 Parameter window a: Switch sensor
This parameter window is visible if the option Switch sensor has been selected under the parameter Input
a in Parameter window Enable inputs a…c, p. 170.
The device features several inputs. However, as the functions for all inputs are identical, only the
functions of input a will be described.
Maximum dead time
This parameter is fixed to a preset 250 ms.
The maximum dead time prevents unwanted multiple operations of the input, e.g. due to bouncing of the
contact.
What is the maximum dead time?
An edge change at the input is assessed with a maximum dead time (delay) value of 250 ms. This
time may vary from 0 ms to 250 ms.
No further bouncing is possible.
