Pulsation Control
Afimilk MPC may be set to control pulsation by means of pulsation rate and ratio. Seven
parameters are used to control pulsation; four parameters for pulsation during milking,
and three optional stimulation parameters.
Pulsator Installation
Pulsators are wired as illustrated in wiring diagram above:
o
The pulsator front is connected to the white/pink wire.
o
The pulsator rear is connected to the white/green wire.
Pulsation Parameters (Milking)
The value of each parameter is selected from a list of options:
o
Pulsation Rate
– the number of pulses per minute.
o
Pulsation Ratio - the ratio between vacuum to atmospheric pressure in the liner at
the milking cup, in each pulsation cycle.
o
FCP – Flow controlled pulsation. This option enables an algorithm to automatically
adjust pulsation rate and ratio during milking according to milk letdown.
Pulsation rate and ratio are set according to the milking machine parameters (Vacuum
level, size of liners, milk letdown…). Use the advice of local extension service expert to
determine the desired pulsation parameters.
Pulsation Rates
Pulsation rates of 0 (no pulsation) 50, 51, 53, 54, 55, 56, 58, 60, 62, 65, 67, 69, 71, 73, 75,
78 pulses per minute are available. (Parameter )
Pulsation Ratios
If the pulsation ratio is the default ratio of 60:40, then the timing illustrated in the
following figure applies:
