Channel settings
In order to select several channels you can enter an ad-
dress area here alternatively to the left mouse button
whilst simultaneously pressing the SHIFT button.
Select here whether the selected channel is to be wired
in a double or single manner.
In the case of safety-oriented circuitry starting from PL d, a two-channel wiring (wir-
ing method = double) will be necessary.
This option is only available in the case of two channel
wired inputs. You can select here between valent (NC /
NC, NO / NO) or exclusive (NC / NO, NO / NC)
combinations.
The channel difference time permits a time delay in the
switching sequence between the individual channels with
two-channel circuitry. The setting range is between 1.0
and 9.9 seconds.
The default of the ‘channel difference time’ is 1.0 seconds. Only change this default
if it can be seen that the sensor used will not be able to observe this time.
