First Time Operation
Air intake compensation
Milking clusters are manufactured with orifices allowing admission of air for improving
milk flow inside milking system tubing. Air intake of these orifices varies from 6 to 12
liters per minute.
Afimilk MPC calibration neutralizes air intake influence. Calibration is
required whenever clusters are changed. Calibration procedure adjusts the value of
parameters "G" (
Air admission Adjustment
) and "H" according to the air admission of the
claws' orifice.
Checks before Calibration
A thorough visual check of the milking parlor is necessary before calibrating. Complete
the following procedure:
1. Check the milking equipment and pipe connections between the milk clusters and the
milk lines. At this point, unless all milking tubing is new, AfiMilk recommends replacing
rubber liners, as well as rubber gaskets and cracked (usually plastic transparent) parts of
used milking clusters.
2. Ensure an open air orifice in each cluster.
3. Check the vacuum lines. Clean and drain.
4. Check the milk meter power supply voltage at the last milking point of each parlor side.
A minimum of 23Vac is required while operating at full capacity.
5. Replace all milk-meter rubber parts if not new.
6. Use a spirit level to check the levelness of the length and width of the top rim of the Milk
meter body mid-section.
7. Remove the body's solenoid diaphragm and ensure that it is complete and flawless
(Replace it if there is any minor difference or flaw). Check for moisture on the underside
of the diaphragm. If moist, dry it.
8. Blow pressurized air into the solenoid from its diaphragm end. Check for clean and free
airflow to the bottom opening of the solenoid.
9. Check all parts of the Milk Meter body, hoses, and connectors.
Steps 5 through 9 below are maintenance steps and may be skipped at initial
calibration (new milk meters).
