4.2 Operation
Operating conditions
The following operating conditions must be met to take milk samples:
• The SHUTTLE must be in a lower position than the milk jar
• The bleed tube strip must be in the up position and the tube end
must be above the 5-kg level (11 lb) of the milk jar
• The bottle rack must be installed with sufficient empty and clean
bottles
• Sampling must be enabled on the milking robot and in T4C
• The SHUTTLE must be connected to the milking robot (CAN-bus and
milk hose).
Sampling
When the SHUTTLE is connected to the CAN-bus of the milking robot, it
automatically switches on and a dot starts blinking on the display. The
fill head moves to the home position, if necessary.
When milking of a cow starts and the milk flow is detected, the milking
robot sends a signal to the SHUTTLE to move to stand-by on a specific
bottle. The fill head moves to that bottle
.
Halfway through the milking, and also when the milking is finished, the
sampling cylinder opens and air is sucked in to mix the milk. The milk jar
is emptied until there is 5 kg (11 lb) of milk in the milk jar. The sampling
cylinder opens and the milk flows from the elbow through the milk hose
to the fill head
5 seconds after opening, the fill head moves down into
position and the milk will flow into the bottle
. When the milk lev
el has
reached the level measure pins the fill head moves up and the mechanical
valve in the fill head closes. The sampling cylinder closes after 20 s (this
time is adjustable).
If no milk is detected (within 60 s), an attention is generated on the
SHUTTLE. If no milk is detected after three attempts, an alarm is
generated. The SHUTTLE continues to sample milk after an attention.
The sampling stops after all alarms.
The sampling cylinder opens and vacuum is applied to the milk jar and
sucks the remaining milk in the milk hose back into the milk jar. The
sampling cylinder closes and the milk in the milk jar is pumped away.
Fill sequence
The fill head starts to fill the first bottle of the first tray at position 1,
continues with the bottle at position 2, and so on, until the bottles of
the first tray are filled. The fill head then moves to its home position to
calibrate. It then continues with the first bottle of the second tray at
position 11 and so on.
It is possible to let the SHUTTLE start at a different position than
position 1. This is set during the setup of the sampling on the X-Link.
The bottles must be installed in a row in the trays.
