If a selector switch is available, the signals via the bus have to match the
actual selector switch position to enable a release. If there is no selector
switch, the release is only controlled by the signals via bus.

enabled to allow actuator operation via the push buttons.
BUS, AUTO LOCAL II
The selector switch positions LOCAL and OFF are enabled via fieldbus.
This setting is only permissible if the local controls is equipped with a selec-
tor switch.

AUAMTIC selector switch position is always REMOTE, irrespective of the
actual selector switch position. In case of bus failure, the selector switch
positions LOCAL and OFF are enabled to allow actuator operation via the
push buttons.
