The robot received information that The robot received information that
there was no vacuum in the there was no vacuum in the
teatcup during an attempt to attach teatcup during an attempt to attach
the cup to a teat. The message the cup to a teat. The message
includes the cow number, cup includes the cow number, cup
number, and which teat the number, and which teat the
attempt concerned. attempt concerned.
The alarm is issued after three The alarm is issued after three
attempts to locate the teat. attempts to locate the teat.
After these attempts, the cup will After these attempts, the cup will
be retracted into the magazine and be retracted into the magazine and
the arm make one more attempt to the arm make one more attempt to
attach the cup. If this attempt also attach the cup. If this attempt also
fails the milking session will be fails the milking session will be
classified as incomplete. classified as incomplete.
In automatic mode, a self-test will In automatic mode, a self-test will

If this error occurs for several If this error occurs for several
consecutive milking sessions, the consecutive milking sessions, the
systems will issue the alarm systems will issue the alarm
"Several milkings failed" (major "Several milkings failed" (major
code 1, minor code 107). code 1, minor code 107).
The position of the rear plate, read The position of the rear plate, read
by the rear sensor, is invalid. For by the rear sensor, is invalid. For
safety reasons, the robot will be safety reasons, the robot will be
