This means that terminal 5 will be “no function” when S8 is made ON. So if you want to
use the terminal 5 with a specific function under the switch S8 is turned ON, you need
to assign manually. Additionally the terminal 3 will also change to no function when the
switch S8 is made OFF again.
Please pay attention not to change the switch S8 needlessly. Otherwise there will be an
unexpected performance of your system.
