5 117 Temperature
teat cleaner... User
notification If teat cleaning water is above 42
degrees Celsius. @@The current
teat cleaning will be aborted. If the sensor indicates a rise in temperature
above the limit:
- Check the water temperature.
- Check the temperature sensor.
(A teat cleaning can be started manually
from the touch screen).
Temporary solutions:
The teat cleaning function can be disabled
for each cow in (PC setting). Note,
however, that this might affect the milk
quality. In addition, this measure is not fool
proof. The cause of the high water
temperature must be investigated and the
problem resolved.
The sensor can also be removed. The
system will then generate the message
"Teatcleaner temp sensor malfunction"
(major code 5, minor code 119). See below. 5 117 Temperature

5 118 Teatcleaner
too hot... User
notification The temperature of the water for
the teat cleaner has exceeded
42deg. System will stop
immidiately.
Note: There is a risk
for milk contamination if teat
cleaning is not used.

malfunction User
notification The system receives information
that the teat cleaning water is
below zero degrees Celsius. The
temperature sensor is damaged or
not installed. Check the water temprature.

cleaning
NOT done Deviation The system was in manual mode
when a scheduled cleaning was
set to take place. (Scheduled
cleanings take place only in
automatic mode.) Start the cleaning. 5 120 Scheduled

5 121 Communicat-
ion lost with
milkroom
controller Stop alarm The milking station has lost
communication with the milk room
controller (node E50 on the
ALCOM bus). Possible cause may
be that the bus is drawn incorrectly. - Check that the ALCOM bus is not broken
or disconnected.
- Check that the bus drawn correctly
between the two units. 5 121 Communicat-

5 122 Teatcup not
tight to jetter Deviation There is air leakage between one
or several of the liners’ mouthpiece
lips and the sealing collars,
impairing the system’s ability to
draw water from the cleaning unit.
The vacuum level/air flow is
detected by the shut-off valves.
If leakage is detected, the system
makes three attempts to reposition
the teatcups. If this fails, the alarm
message will be issued.
This alarm message will not stop
the cleaning process, but there is a
risk that the air leakage will cause
the cleaning unit to issue a timeout
alarm (major code 7, minor code
4). The timeout alarm will halt the
system. - Check the length and condition of the milk
tubes. Make sure that the teatcups can be
released onto the jetters and their sealing
collars easily. 5 122 Teatcup not
