Padlocking mode

3KC3 and 3KC6 transfer switching equipment can be locked with a padlock. This is normally only possible in position 0. However, it is possible to allow padlocking in positions I and II in addition if a deliberate change is made (see section titled Changing the preset padlocking setting - optional).
