Maintenance an calibration
The following points are important to sustain
correct dosing of etergents. Note that
these two tasks should be performed by an
authorised DeLaval service engineer.
• The tubes in the peristaltic pumps should
be replaced at least two times a year.
• The dosing volume (P6-P8) of the
detergent pumps should be checked
every third month. The dosing capacity
(P32-P34) may need to be adjusted.
Starting cleaning or rinsing
from the touch screen
Note: Any ongoing backflush process must
first be finished before cleaning or rinsing
can be started.
1. Ensure that the milking station is in
manual mode.
2. Remove any cow that might be in the
milking station.
After treatment window
Note: Both gates should be closed to
prevent a cow from entering before the
system cleaning has been started. Closing
and opening gates is done in the Stall
control window.
3. Press the tab After Treatment on the
touch screen to display the After treatment
window.
4. In the After treatment window, press the
Cleaning and Rinsing button. This will open
the Cleaning and rinsing window.
3 Herd Navigator 100 sampling
workflow
The Herd Navigator 100 sampling routine is per-
formed in the VMS when the cows are milked.
1. Herd Navigator 100 receives milk from the
VMS controller via the single sample out-
take pump (SSO) (A).
2. The peristaltic milk pump (C) uses the new
milk to clean the tube from milk residues
from the previous sample and saves milk
for the new analysis. The needle (G) is in
the drain position and the first milk goes to
the drain.
3. The peristaltic diluent pump (E) runs at the
same time as the peristaltic milk pump (C).
The speed of the pumps is set by a mixing
ratio.
4. The mixing chamber (F) mix milk and
diluent (D).
5. The pumps stop, and needle (G) and stick
(H) move to the dose position.
6. The pumps start again and a dosage of 45
microliters of mixed milk and diluent is
applied to the stick (H).
7. A chemical reaction takes place in the stick
(H) and it is coloured.
8. The incubation time (around 5.5 min)
begins.
9. The stick (H) moves to the optical reader
which scans the intensity of the stick colour.
The measurement of the progesterone
concentration is then transferred to the bio-
model software.
10.The peristaltic milk pump (C) runs to empty
the tubes from residues and sends it to the
drain (the needle is in drain position).
11.The biomodel processes the analysis
results and communicates them to the Del-
Pro farm manager.
The Herd Navigator 100 is cleaned in the ordi-
nary VMS cleaning/rinse. During cleaning, the
needle is in the drain position throughout the
whole process.
