2 DESCRIPTION OF THE MACHINE

General characteristics 2.1

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.

5760006_02.17_EN

Washing 4.2

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.

5760006_02.17_EN

ACR Smart MMV - Instruction Manual, Operation and

Maintenance original instructions

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 shut­off 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).

Milking 4.3

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 AUTO­START 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 - 16

ACR Smart MMV - Instruction Manual, Operation and

Maintenance original instructions

5760006_02.17_EN

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.

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 operation 4.4

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.

Reattachment 4.5

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.

Stimulation 4.6

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.).

Alarm 4.7

If a continuous flow is not detected during the milking process, when the Initial delay has elapsed and during

the subsequent final delay time count, the red alarm LED starts flashing and the unit removal
procedures start automatically.

Press the to reset the alarm and switch to the detachment mode (stand-by), the alarm lamp and the

alarm LED stop flashing and detachment led stays fixed on.

Press the to start a new milking session.

Quick-Lift 4.8

The quick-lift button corresponds to pressing the key on the panel.
If terminals 7-8 on all the panels are connected to an external button, by pressing this key you can lift or
release all the units at the same time. This way, at the beginning of the milking process, you can release all
the units at the same time.

WARNING

Do not activate the quick-lift button during washing or during milking; milking units would be
all removed from animals or from washing dishes.

Swing-over (only with detachment made by pneumatic cylinder) 4.9

By activating the Swing-Over mode (type of detachment dEt.t = S.OVE. parameter) the ACRSmart MMV
panel can manage systems in which the unit is detached via a pneumatic piston that moves the Swing-Over
arm from one side to the other.
By connecting this piston to the CV output, normally dedicated to the DVC, and setting Type of System
parameter (det.t.) on value S.OVE., at the end of the milking process the panel will automatically move the
arm in order to start milking again on the other side.

Therefore, via the button or via the remote Quick-Lift button, you can move arms from one side of
the milking parlour to the other.

Calibration (with MMV) 4.10

The parameter CAL.M. is used to calibrate the MMV sensor for each ACRSmart MMV of the parlour. Each
installation requires different settings due to the different vacuum level, tube length, air input and milk
ascent/rising.

It’s recommended to calibrate the system once a year.
Use pure water without acid or salts. The calibration must be done on clean sensors.
Each parameter CAL.M. corresponds to ±1%.

WARNINGS

- We suggest calibrating the system after one week of system operation because the parts
must adapt to function properly. On average, the calibration parameter fluctuates by 2 points
after the parts have settled.

- We suggest calibrating the system at least once a year for best operation.

4.10.1 Equipment

A SUCTION SET composed by:

- Plastic pipe with a sucking hole of Ø 3.5mm

- Plastic pipe with an air inlet 1 mm

Connect the two parts with a piece of rubber hose and prepare a second tube to connect the set to the
sensor.

4.10.2 Testing proceeding

1. Remove the cluster from the milk hose and connect the suction device with a rubber chunk

2. Fill the bucket with 10l (0.35 ft3) of water (=10Kg – 22.04 lb). The temperature of the water should be

approximately 25°C ±10°C (77°F ± 50°F) without salt or acid.

3. From stand-by mode, start a new automatic milking with button

4. Put the suction device in the bucket taking care that the 3.5mm (0.14 in) hole remains always under

the water level until the container is completely empty and the air inlet hole remains above the water
level.

5. Completely suck the 10l (0.35 ft3) of water, waiting the automatic detachment of the panel

6. At the end of detachment operation, the panel shows the milk yield (if the display features the milking

time, press key to show milk yield).
With a properly calibration, the display should show 9.6±0.1 kg (21.16±0.22 lb) (You may have slight
variations in the specific weight depending on the animal milked and the type of alimentation)

7. Take note of the measured value

8. If the measurement is different from the reference value (9.6 kg - 21.16 lb) of ±0.1kg (0.22 lb), then

the calibration is correct and no further check is necessary.

9. If the different is more than ±0.1kg (0.22 lb) proceed with 2 further tests, taking note of the values

10. Calculate the average value between the errors of the 3 measurement

11. Now it’s necessary increase/decrease the parameter of calibration CAL.M. of 1 step for each 0.1kg
(0.22 lb) of difference from 9.6 kg (21.16 lb).

E.G.

After 3 tests you have the following results

The panel underrates an average error of 0.3kg (0.66 lb) for each milking. So you have to increase the
parameter of calibration CAL.M. of 3 steps.

WARNINGS

If calibration is carried out during plant testing (or just after having carried out routine
maintenance on the MMV), without waiting for the week suggested to allow the parts to settle,
with 10 kg of water in the bucket the panel must measure 9.8±0.1 kg (21.6±0.22 lb) and not 9.6
kg (21.16 lb) as specified in the standard procedure.

Positioning 6.1

Make sure that the volumetric milk meter MMV or the flow sensor HFS are in vertical position

Sensitivity (only with HFS) 6.2

The ACR panel is designed to detect milk flows below the 100 gr/min limit (preferably with the HFS sensor).
It is possible (but NOT recommended) to increase or decrease this threshold via the jumpers on the board.

CAUTION

Power off 6.3

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.p.
