2 DESCRIPTION OF THE MACHINE
General characteristics2.1
The ACRSmart MMV is a panel designed to control all the functions of milking, washing and detachment of
the unit.
Furthermore, with InterPuls Milk Meter, ACRSmart MMV is able to measure the milk production with errors
below 2%.
The panel can work with Milk Meter InterPuls and also with flow sensor HFS InterPuls.
The ACRSmart MMV is able to control the milking frequency and the pulsation ratio in a wide range of values
in order to meet the needs of all system (both in high line and low line) and of all type of animals (cattle –
sheep –goat).
The ACRSmart MMV is able to perform a stimulation that can be forced, automatic (dependent on the flow of
milk) or manual (activated directly by the milker at any time).
The panel is compatible with swing-over systems in which the unit is detached by moving the arm. In fact,
with the ACRSmart MMV you can control the pneumatic cylinder responsible for moving the unit from the
right hand row to the left hand row and vice versa.
It is suitable for milk transport systems thanks to the alarm indicating the end of the milking process and the
possibility to restart the panel from the last active stage.
The ACRSmart MMV can be connected to remote start-up devices (AutoStart) and remote stop devices
(Quick Lift Line).

2.3.3 Choice of CV
It’s possible to set the ACRSmart MMV panel in order to use solenoid valves normally open or normally
closed by setting the following parameters:
- E.S-O : shut-off solenoid valve
- E.DVC : cylinder solenoid valve
- E.dMP. : dump valve solenoid valve
Set these parameters on:
- N.OP. (normally open) if the utility is connected to a VAC channel of the CV (eg. for CV20 or left
channel of CV30 inv)
- N.CL. (normally closed) if the utility is connected to a ATM channel of the CV (eg. for CV30 or
right channel of CV30 inv)
The default settings require the utilization of a CV20 for cylinder (E.DVC = N.OP.) and a CV30 inv for
shut-off and for dump valve (E.S-O = N.OP. , E.dMP. = N.CL.)

4 DESCRIPTION OF THE FUNCTIONS
Upon start-up the panel display indicates the software version installed. Depending on the configured
settings (parameter In.P.), then the panel starts during:
- washing
- detachment (default)
- last active phase
Detachment phase (stand-by)4.1
Depending on the settings (parameter dEF.P.), the panel shows the milking production (point on
symbol) or the milking time (point on symbol) of last animal; at the start, the display shows time and
production equal to zero.
Green led of detachment is on to signal that the cluster is in removal position. The S/O valve stays
closed, while the unit position may switch from release to removal or vice versa by pressing STOP button
or via cluster up/down line; when the unit is released, the green led turns off.

Washing4.2
The wash phase can be operated:
Manually when the system is in detachment position by pressing together + briefly
Automatically if pre-set as the start-up phase on the programming menu (parameters In.P. set on
diS.)
By pressing STOP button during washing, the phase stops and the panel returns to stand-by mode,
the unit is not removed from washing plate.
By pressing again the STOP button the cluster is removed.
CAUTION
At the end of washing phase it’s recommended to power off the ACRSmart MMV panels to
avoid that the coils of control valves stay powered for long time and being damaged. Upon
start-up, the panel may restart in washing phase or detachment phase according to the
parameter In.PH.
4.2.1 Washing with HFS
Washing visualization with HFS
The display features the code diS. And the green washing led starts blinking. The unit is released and
the count relating to the shut-off closure delay starts (parameter c.S.d.). When it is elapsed, the shut-off
valve is opened and the washing stage starts.
It’s possible to change the frequency during washing (parameter diS.F.).
Press the STOP button or the cluster up/down command to stop washing cycle and retract the unit.

MI - 16
4.2.2 Washing with Milk Meter
The panel alternates FILL phase and EMPTY phase; between the two phases, the dump-valve is activated
to allow the emptying of the sensor.
During the FILL phase, the dump-valve stays closed to permit the complete filling of the milk meter to wash it
in each of his part. The FILL phase lasts for the Fill time (parameter FILL).
The display features code “F” and the temperature of the water.
FILL phase with water at 63°C (145.4°F)
During the EMPTY phase, the dump-valve is closed until the floater reaches the second level. Then the shut-
off stays open as setting in the parameter Dump time (parameter dMP.t.) to discharge the water. After that
the milk meter starts again to fill and to discharge until the Empty time elapsed (parameter EMPt).
The display features code “E” and the temperature of the water.
EMPTY phase with water at 51°C (123.8°F)
The washing parameters have to be modified to allow the complete filling and emptying of the sensors.
Depending from the parlour configuration, you may need to set different values of FILL and EMPt
parameters to allow the correct washing of each sensor.
In the milking points far from the water entrance, if there isn’t enough water to completely filling of the sensor
(FILL PHASE), it’s necessary to increase fill time (parameter FILL); equally, to make available more water,
it’s also possible to increase empty time (parameter EMPt).
Milking4.3
4.3.1 Milking with automatic cluster removal
To start the milking process with automatic detachment press the START button during detachment
phase or operate the Auto-start contact.
NOTE
The connectors 5-6 (clean contact) can be connected to a REMOTE BUTTON or an AUTO-
START cylinder to start a milking without using button.
When the milking with automatic detachment starts:
Cylinder releases the unit
After the Vacuum/pulsation delay (parameter PuL.d.), the pulsator is activates and the shut-off valve
is opened.
4.3.2 Milking with HFS
At the beginning of the milking, the display shows the milking time and the panel counts of Initial delay
(parameter In.d.).
When the milking presence signal constantly exceeds the value defined by the position of the jumpers, the
panel detects a presence of milk and the first dot on the right starts blinking.
If the presence of milk lasts more than Continuous flux time (parameter M.d.F.), the panel detects a real milk
flux.

MI - 17
The panel shows the milking time in MM.SS size; the central dot is on clock symbol .
At the end of Initial delay (parameter In.d.) when there’s no longer milk flux, the count of Final delay
(parameter Fin.d.) starts; the detachment operations start when this delay has elapsed.
Milking time (4minutes and 58 seconds) with milk flow
During all milking stages, press the START button to switch from automatic to manual milking and
vice versa.
Press STOP button (or activate the Cluster up/down button) to immediately stop the milking and
start the detachment operations.
4.3.3 Milking with MMV
At the beginning of the milking, the panel starts counting of Initial delay (parameter In.d.).
The display can show:
- Milk yield (if parameter dEF.P = MiLK) –point on symbol
Milk yield (14.8 Kg)
- Milking time (if parameter dEF.P = tiME) –point on symbol
Milking time (2 minutes and 17 seconds) with milk flow
It’s always possible to pass from milk yield to milking time visualization and vice versa by pressing
button.
During milking, the point in the right corner of the display shows if in that moment there’s milk in the sensor. If
the milk flow is higher than the parameter Detachment flow (parameter dEt.F.), the panel detects a
continuous flow.
At the end of Initial delay (parameter In.d.), when there is no longer any milk flow, the panel start counting
final delay (parameter Fin.d.). The detachment operations start when this delay has elapsed.
During all milking stages, press the key to switch from automatic milking to manual milking and vice
versa.
Press the key (or activate the quick-lift button) to immediately stop the milking operations and start
the detachment operations.

the button is pressed to switch to the automatic milking mode
or
the button is pressed to start the detachment operations
Press the key to switch from the manual milking mode to the automatic milking mode and vice versa,
at any time.
4.3.5 Maximum milking time
WARNING
You can envisage a maximum milking time, which can be set or disabled in the programming
menu (parameter M.M.t.)
If this limit is reached, the unit detachment operations start automatically and, in the event of
no flow during the milking process, the anomaly is signaled via an alarm (see chapter 4.7
Alarm)
Detachment operation4.4
When the Initial delay (parameter In.d.) has elapsed, if the panel does not detect a continuous flow (HFS) or
a minimum flow (MMV) of milk, the final delay count starts (parameter Fin.d.) and the green led of
detachment starts flashing .
If the flow of milk is resumed, the delay is reset. The unit removal operations start when the final delay has
elapsed.
The removal procedure can also be started manually by pressing the key o by activating Quick-Lift
button.
When the detachment operation start:
the pulsator stops
the S/O Valve closes the vacuum passage
the detachment delay time count starts (parameter det.d.), in order to wait for a certain amount of air
to leak through the collection unit hole, lowering the vacuum level under the nipples before removing
the unit
when the delay has elapsed, the cylinder gently removes the unit and the green led stays fixed
on.
if the suction function has been activated (parameter SPt.L.), when the suction delay time has
elapsed (parameter SPt.d.) the residue milk in the collection unit and in the milk pipe is aspirated
through the flow meter.

if the automatic unit release function has been activated, when the automatic release delay has
elapsed (parameter A.r.d.) the unit is released automatically to start a new milking session.
At the end of detachment operation the green led of detachment stays fixed on and the display shows
the milking time or the milk yield (only with MMV). The pair of terminals 3-4 is powered at 24VDC; the pair of
terminals can be connected to a flashing light for indicating the end of milking.
Press the key to switch off the flashing light and the cylinder releases the milking unit (you can put it
on washing plates).
Press key to start a new milking session.
Press key to switch the display visualization from milking time to milk yield and vice versa (only with
MMV).
If you press and hold key, the display shows the total milk yield from the last reset (only with MMV).
If you press and hold key and then press also key, the total milk yield is reset.
Reattachment4.5
At the end of detachment operation, if the farmer believes that the animal still has milk, it’s possible to make
a reattachment, that is a new milking but without milking time and milk yield reset (these data restart from
the values of the last detachment).
To make a reattachment, press and hold key and then press also key. The reattachment is like
a normal milking and at the end start the detachment operation.

Stimulation4.6
At the beginning of stimulation, the display features the code St.on. for 3 seconds.
On the programming menu you can define the type of stimulation (parameter St.tY.) which may be:
Forced (Forc)
Automatic (Auto)
OFF (oFF) –can only be activated manually
FORCED STIMULATION
During programming you can set a forced stimulation cycle at the beginning of each milking process.
For a certain period of time (stimulation time, which can be set via parameter St.t.) the frequency
and pulsation ratio are gradually modified in order to reach the set values (stimulation frequency
St.F., stimulation ratio St.r.)
AUTOMATIC STIMULATION
Stimulation starts if the function is enabled and if during milking the sensor does not detect presence
of milk for a certain period of time (called neutral time, which can be set via parameter nEU.t.
Therefore the frequency and pulsation ratio vary gradually until reaching the values set for
stimulation (stimulation frequency St.F., stimulation ratio St.r.)
Stimulation stops when the flow meter starts detecting a presence of milk again or when the
stimulation time elapses (parameter St.t.)
MANUAL STIMULATION
Press and hold the key for 3” during the milking cycle (with any value set for parameter
St.tY.) to start the manual stimulation process: the frequency and pulsation ratio vary gradually until
reaching the values set for stimulation (stimulation frequency St.F., stimulation ratio St.r.).
Stimulation stops when the stimulation time has elapsed (parameter St.t.).
A couple of second before the stop of stimulation, the display features the code St.oF. for 3 seconds, after
that the frequency and pulsation ratio gradually go back to the values set for milking. Then the display
features again the milking time or the milk yield
NOTE
By setting stimulation ratio (parameter St.r.) on value 0, upon start of the stimulation, the
liners stay completely closed and the pulsation stops until the end of stimulation time (St.t.).
