Milking arrangement, and a method of operating a milking arrangement

A method of operating milking arrangement comprising at least one robot milking station (1) comprising a set of teatcups (2), a milk receiving unit (3), and a milk pump (4),

• a milk conduit (6) to which the at least one robot milking station (1) is connected and which comprises an outlet end (7),
• a connection conduit (8) which is connected to the outlet end (7) of the milk conduit (6) and comprises a outlet member (9),
• a cleaning device (10) configured for cleaning of at least the milk conduit (6) and the at least one milking station (1), the cleaning device (10) comprising a cleaning conduit (11) having a first connection member (12), and
• at least one milk tank (20) comprising a second connection member (22), and
• a sensor arrangement (30-32),
• a user interface (41), and a controller (40) communicating with the at least one robot milking station (1), the cleaning device (10), the sensor arrangement (30-32), and the user interface (41),
• wherein the outlet member (9) of the connection conduit (8) is movable between different states, including a primary state in which the outlet member (9) is connected to the first connection member (12), and a secondary state in which the outlet member (9) is connected to the second connection member (22), and the sensor arrangement (30-32) is configured to sense when the outlet member (9) is in the primary state and when the outlet member (9) is in the secondary state,
• the method comprising the steps of:
• the controller (40) determining, via an order, that the state of the milking arrangement is to be changed, the change of the state of the milking arrangement including a change of state of the outlet member (9) of the connection conduit (8);
• the controller (40), upon determining that the state of the milking arrangement is to be changed, automatically performing measures for preparing the milking arrangement for the change of the state of the outlet member (9) of the connection conduit (8);
• and
• the controller (40) indicating via the user interface (41) to an operator that the measures have been performed and that the milking arrangement is ready for the change of the state of the outlet member (9) of the connection conduit (8).
