Operation
1 About collecting milk samples
A sampling sequence normally takes 24 hours
and is to be stopped after performing a system
cleaning. This way, the sampler will be cleaned
after the sampling.
Before starting a system cleaning, putting the
milking station into manual mode is recommen-
ded. This makes it possible to disconnect the
sampler before milking restarts. Consequently,
milk residues in the milk sampler during storage
or transportation will be avoided. When a system
cleaning is inconvenient or impractical, see the
section "Manual cleaning" in the Operators main-
tenance.
Reports about sampling sequences can be
accessed in the management software. Sam-
pling reports are located in Default Reports >
Milking > Milk Sampling. For more information
about reports, see the help file in the DelPro soft-
ware.
2 Collecting milk samples
There are three main steps when collecting milk
samples:
nConnecting the milk sampler
nStarting a sampling sequence
nStopping a sampling sequence

2.1 Connecting the milk sampler
1. Stop the cow traffic through the milking sta-
tion. Milking must not take place when the
steps below are in progress.
2. Place the milk sampler in front of the milk-
ing station on an even surface.
3. Shut off the vacuum to the receiver by pull-
ing off the hose to VV401.
4. Attach the milk hose to the milk pump con-
nection on the milk pump.
5. Connect the electrical cable to the ALCOM
bus connector (B) on the control box (A).

6. Remove the air-purge valve and mount the
return line connection (D).
7. Connect the return line (E) to the return line
connection.
8. Turn on the vacuum to the receiver using
the manual valve.
2.2 Starting a sampling sequence
When the milk sampler has not been used more
than three days it may need to be cleaned before
being used again. That is why the sampling
sequence is normally started just before a system
cleaning.

The ordering of the sample tubes can be
changed in Sample tube deposit ordering in the
management software (VC configuration). Four
different options are available (A, B, C, and D).
Note! Make sure to check the settings for milk
sampling in the management software (VC con-
figuration) before starting a sampling sequence.
For further information, see the DeLaval DelPro
software, VMS (Help file).
Sampling is performed by using the touch screen.

1. Press the VMS Menu button in the top right
corner to display the VMS menu.
2. Press the Milk Sampler button.
3. Press the Start button to display the Milk
sampler window.
4. Select a sample bottle by typing the bottle's
number on the keypad. The illustration
shows the first bottle for configuration (A) in
the VC configuration.
Note! The first bottle is located differently
depending on the configuration in the VC
configuration.
nFor normal sampling type one (1) for
the first bottle.
The first bottle (1) is located differently
depending on the configuration in the
management software (VC configura-
tion), see above.
nFor continuous sampling, when the
sampling sequence will continue with a
new rack, use the coming number after
the last bottle number of the previous
rack. In other words, if the sample tray
has contained 130 bottles in the first
place, it is possible to continue the
sampling sequence by typing the bottle
number “131”.
Use the Cancel button when typing the
wrong number.
5. Press Ok
6. Press the Start button to start the sampling.

2.3 Stopping a sampling sequence
A sampling sequence is stopped manually from
the touch screen, after a system cleaning.
1. Put the milking station into manual mode
and start a system cleaning. The runner
then goes to the 0 (zero) point.
2. After the system cleaning, press the Stop
Milk Sampling button on the Milk sampler
window.
3. With the runner still in the 0 (zero) point
position, disconnect the milk sampler from
the milking station.
Note! The sampler must be disconnected
before milking restarts to avoid milk resi-
dues in the sampler during storage or trans-
portation.
4. Remove the sample tray (B) and flush the
sample compartment (C). To prevent water
from damaging the electrical parts, close
the control box cover (A). Make sure that
the runner is clean.
5. Check the silicone tubes for damage.

Operators maintenance
Note! This chapter is intended for the customer.
1 About carrying out maintenance
In normal circumstances, the milking station will
carry out the cleaning process on the milk sam-
pler during a system cleaning. Manual cleaning
will only be performed when the milk sampler has
not been cleaned by the VMS.
If any parts such as a silicone hose has been
damaged or deteriorated, additional mainte-
nance will be needed.
1.1 Manual cleaning
Tools: Syringe without needle.

1. Open the control box cover (A) and the
main cover (B).
2. Disconnect all hoses (B) from the milk con-
tainer (A), then remove the container.
3. Use a syringe without a needle to clean the
disconnected hoses.
3.1 Fill the syringe with lukewarm water,
press the tip of the syringe into one of
the hoses and then inject the water
through the hose. Repeat the same
procedure for all hoses.
3.2 If there are any dirt or milk residues left
in the hoses, remove the hoses and
rinse them with lukewarm water, then
wash them using a mild detergent,
then rinse again with water to remove
detergent.
3.3 If the milk sampler has not been
cleaned for a long time, milk residues
may be impossible to remove, in which
case the tubes is to be replaced. For
more information, see Ä Chapter 2
"Additional mainte-
nance" on page 13.
4. First disassemble the container, then rinse
it with lukewarm water and clean with
appropriate detergents. Finally, rinse again
with water to remove detergent.
5. Reconnect the hoses onto the container.
Note! It is important not to shorten the
hoses too much if they have been deterio-
rated.

6. Reassemble the container. Note that the
cylindrical cones (B) must face each other
and be properly inserted in the clip (A).

The three hoses (A and B) must be changed if
they have been deteriorated or if they not can be
cleaned properly. Due to the complicated opera-
tion, only the hose changing on the tube wheel

3. Remove the silicone hose (A) from the hole
by slowly rewinding the silicone hose onto
the tube wheel using a finger.
4. Pull the silicone hose and remove it from
the hole.
Note! Keep a finger on the tube wheel to
prevent it from revolving too fast. If the tube
wheel rotates freely, the spring will be dam-
aged and must then be replaced.
5. Return the wheel slowly to the start posi-
tion.
6. To fit a new silicone hose onto the tube
wheel, turn the tube wheel 8 times clock-
wise.
7. Push the silicone hose through the hole in
the wheel.
8. Allow the spring to rewind the silicone hose
on to the wheel.
9. Reinsert the sample tube into the silicone
hose.
