Funnel
Dispenser
Feed from the dispensers is collected in a
funnel, and a tube leads the feed from the
funnel via a tube to the manger. Up to two
feed dispensers can be installed, each with
a different feedstuff.
Like the exit gate, the manger also has a
transponder reader that identifies each cow
carrying a transponder. Cows are identified
when they put their heads down to access
the feed.
Note: Calibration of the feed dispensers is
important to the feeding precision. Calibrate
at regular intervals and each time a new
feedstuff has been delivered and comes
into use. The calibration is done by using
the touch screen.
Service switch
Service mode Working mode
The service switch is a safety device that is
used when you need to enter the working
range of the milking station. When the
service switch is in service mode any
sequence is stopped, the moving parts are
blocked and remote operation is not
possible. The parts can, however, be moved
by manual commands. Turning the switch
back to operation mode will make the
milking station ready for operation again.
Management and supervision
Data communication and the VMS
management software
Data communication is an essential feature
of the VMS system. The core elements of
the VMS system are the milking station and
a management software that runs in the PC.
The computer inside the milking station and
the PC are interconnected and exchange
data during operation.
The data can be classified into two main
categories: data that control the way the
system and the station operate and animal
data such as milk yields and feed
consumption. Data of the first type are
transferred to the station at start-up while
the second are transferred continuously
between the milking station and the PC
