When moving the switch in / out to a different location (eg. Connected –> Test),
the button of the ATS racking in/out mechanism "PUSH BEFORE OPERATING"
must be pressed, and when the button is pressed, the HMI displays the
information "Racking Enabled". For safety reasons, the switch cannot change
position during a move to different locations.
