4 104 Error ... on
gate ...
User
notification
Nonspecific gate-error message.
(Error code to be defined)
In general, errors of this kind
means that a gate has - after
several retries - failed to complete
an operation in a safe way and had
to "commit suicide" (air off) to
obtain a safe state.
Restart the milking station that controls the
gate which caused the error.

4 105 Failed to
release cow.
Cow still in
stall
User
notification
A notification from the cow-traffic
system that a cow has stayed too
long inside the station after the exit
gate has been opened.
The system will continue to wait for
the cow to leave the station, and
the complete its operation.
Most probably, this is due to a cow that
refuses to leave the station. Either ignore
the message and wait until the cow leaves
by herself, or visit the barn to make her
leave the station.
If this message appears several times, the
cow traffic might be blocked for some
reason: a cow outside the milking station, a
broken one way gate, etc. Visit the barn and
remove the obstacle.
If this message appears repeatedly and
there is no cow inside the station, the "cow
inside station" sensor might be defective.
Contact service engineer.

or others sources of disturbing light
reflected on surfaces in the barn.

4 107 Selection
gate …:
Failed to
close gate.
Gate put into
manual mode
User
notification
Several attempts have been made
to close the selection gate, but
without success. The gate was
then simulated to be out of
operation to allow cows to clear
away from the gate. More attempts
to close the gate were made, but
the gate still failed to close and
was opened and put into manual
mode.
Visit the gate and check that no cow or
other object prevents the gate from closing.
If this is not the case, press the AUTO
button on the keypad twice to put the gate
in automatic mode again.
If the alarm is issued frequently, either of
the following two might be the cause:
- Air pressure to gate is insufficient,
- Communication with the ALCOM I/O
board is unstable.
If the alarm is issued constantly, the
gate-closed sensor on the cylinder might be
damaged.

4 108 Separation
gate…:
Failed to
reach
designated
direction.
Gate still in
automatic
mode
User
notification
The separation gate has after
several attempts failed to reach the
end position of the specified
direction. The gate has stopped
trying to reach the end position,
but is still in automatic mode.
If this alarm is issued only occasionally, it is
probably because a cow has not moved
away from the gate. To be on the safe side,
visit the gate to ensure that no cow is
injured or is blocking the gate.
