values.
Note: This will occur if a teaching
procedure is started without the
joystick connected, or if any
joystick button is kept pressed
when a teaching procedure is
started. -Make sure the joystick is connected
properly.
- Restart the teaching procedure.
- If the alarm is issued again, restart the
milking station and make another try. 2 114 Joystick is

Service engineer only:
- Check or, if necessary, replace the
joystick.
- Check that the voltage supply to ALCOM
I/O board is 24V. If the voltage is incorrect
that will affect ALCOM I/O board. Service engineer only:

2 115 Teatcup ...
not detected
in gripper Stop alarm This error can be caused by either
one of the following two events (1
or 2):
1) While attempting to fetch a
teatcup, the gripper on the
multi-purpose arm fails to detect
the cup in its claws. The arm will
attempt to fetch the cup twice, the
magazine release and retract the
cup and the arm make yet another
attempt. The multi-purpose arm
will then attempt to fetch the
remaining teatcups in the same
manner.
In automatic mode, the system will
perform a self-test while the cow
remains in the station: if the test is
successful, the system will
continue operating; if not, the
system will be stopped. A) - If this rarely ever occurs, then try
desired action once again.
B) - If this occurs often, make sure the arm
is in the correct position when fetching the
cups. Follow the steps below.
Warning: Stay out of the arm's operating
range during the calibration and the test
below.
- Put the station in manual mode.
- Carry out an Axis End point Calibration: on
the touch screen, open the Robot Control
window, then press the button "Axis End
point Calibration".
- Verify that the arm can fetch the teatcups
by pressing the button "Test Pickup Cups"
(in the Robot Control Window on the touch
screen). Check that the gripper is tilted to
correct positions. If not call service
engineer; otherwise, continue with the next
step.
For magnetic gripper: the contact surface
between gripper and teat cup might be dirty.
Clean if necessary. 2 115 Teatcup ...

2) The multi-purpose arm detects
that it has dropped the cup while
attempting to locate a teat. The
alarm will in this case be issued as
a Deviation. The cup will be
retracted into the magazine and
the arm make additional attempts
before the system issues “Teat not
found…”, major code 2, minor
code 51 or 52. The system will in
this case continue operating in
automatic mode. - If the arm does not succeed in fetching the
cups or the performance is slow, then
redetermine the cup positions: open the
Robot Teaching window, then press the
"Teach all cup positions" button and follow
the instructions on the screen.
- Carry out the test by pressing the "Test
Pickup Cups" again.
- If the arm still fails or the performance is
slow, contact the service engineer. 2) The multi-purpose arm detects
