Abstract: The present invention relates to a vacuum source for providing vacuum to at least a first vacuum drain through conduits, comprising at least a first and a second vacuum pump. The vacuum source comprises a control system adapted to detect the consumed airflow, and to control the operation of each of the first and second vacuum pump based on the detected airflow.

Abstract: An arrangement and a method for indicating an undesired detachment of a milking member from an animal in a milking stall. The arrangement includes a removing device adapted to detach the milking member from the animal and move the detached milking member to a parking position when the milking process has been completed, and a supervision device adapted to supervise when the milking member has been detached from the animal before the milking process has been completed. When the milking member has been detached from the animal before the milking process has been completed, the removing device is adapted to move the undesirably detached milking member to an indicating position located at a distance from the parking position.

Abstract: A fluid application system for automatically applying a fluid to the teats of an animal subsequent to the milking of the animal comprises a fluid delivery arrangement comprising a plurality of applicators, wherein each of the applicators is arranged in connection with a respective teat cup and is provided for applying the fluid to a teat of the animal, to which the respective teat cup is attached during the milking of the animal, in connection with a detachment of the teat cup from the teat. A control arrangement is provided for (i) determining, for a detachment of a teat cup from a teat, whether that detachment is a normal detachment or an abnormal detachment, and (ii) controlling, for the detachment of the teat cup from the teat, the applicator arranged in connection with that teat cup to apply the fluid provided that the detachment is a normal detachment and to not apply the fluid provided that the detachment is an abnormal detachment.
