Automatic determining/determination
of all teat positions
Cows returning from calving to a new
lactation have often changed in udder
shape. If this is the case, the position of
each teat must be re-established before the
cow can be successfully milked in the VMS
again.
Note: Automatic determining of teat
positions is not suitable for new cows before
they are thoroughly accustomed to the VMS
and the multi-purpose arm. Even if they
have had enough experience with the stall
to tolerate manual determination with
multi-purpose arm and joystick,
unaccustomed cows will jump and move too
much for a successful automatic
determination.
Note: Automatic determining of teat
positions only works for cows with four teats.
Automatic determination of teat positions is
enabled on a per cow basis in the the
management software. For more
information, see chapter "VMS cow
settings" in the instruction book "VMSMgmt
2007".
Milking station in automatic mode
When a cow with milking permission enters
the stall in automatic mode and automatic
determination of teat positions is enabled for
her, this will be performed without any cup
in the end effector before teat cleaning or
cup attachment. If successful, the new teat
positions are saved in the VMS database
and subsequently used. If less than four
teats are identified within a maximum time
of 3 minutes, no change is made in the VMS
database.
Milking station in manual mode
In manual mode, automatic determining of
teat positions for a cow in the stall can be
commanded from the touch screen. Make
sure the cow is correctly identified.
