2 DESCRIPTION OF THE DEVICE

General features 2.1

The ACR-Smart panel is designed to control all the milking, detachment and washing functions of the unit.
The ACR-Smart 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 systems (both in the high line and low line) and of all types of animals (cattle ­sheep - goats).

The ACR-Smart 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 ACR-Smart 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 ACR-Smart can be connected to remote start-up devices (AutoStart) and remote stop devices (Quick Lift
Line).

4 DESCRIPTION OF THE FUNCTIONS

Upon start-up the panel display indicates the software version installed. Depending on the configured
parameters, the panel may then restart during:

 washing
 detachment (default)
 last active stage

Detachment stage (stand-by) 4.1

The display features the code dt (Detachment) with the green LED switched on. During this stage the panel
waits for the commands from the operator.
The S/O valve therefore stays closed, while the unit may switch from the release position to the removal

position or vice versa via the key or via the Quick Lift control

Wash 4.2

The wash function may be operated

 manually, when the system is in the detachment position, by pressing the two + keys

instantaneously

 automatically if pre-set as a start-up function on the programming menu (parameter I.P. set on L.p.).

The display features the code CL and the green LED starts flashing. The unit is released and the count
relating to the shut-off closure delay starts (parameter c.S.). When it has elapsed, the valve is opened and
the washing stage starts.
You can set a different frequency during the washing cycle (parameter U.F.).

Press the key to stop the washing cycle and retract the unit.

CAUTION

At the end of washing phase it’s recommended to power off the ACRSmart 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 I.p.

WARNING

Do not press the key and do not press the quick-lift switch during the washing cycle:
the unit would be removed from the washing plate.

Milking 4.3

Milking with automatic unit removal 4.3.1

To start the milking process with automatic detachment press the key during the detachment stage
or operate the Auto-Start contact.

NOTE

Terminals 11-12 may be used to connect a REMOTE KEY or an AUTO-START device to start
the milking process without having to press the key on the panel

When the automatic milking process starts:

 the cylinder releases the unit.
 after the vacuum/pulsation delay (parameter P.d.), the pulsator is activated and the valve (shut-off)

of the flow sensor is opened.

The display then starts counting the milking time. The upper horizontal segment indicates the initial delay
count (parameter I.d.). At the same time, the two vertical segments indicate the opening of the pulsator
channels, flashing alternately.

When the milk presence signal constantly exceeds the value defined by the position of the jumpers, the
panel detects a continuous flow and the horizontal segment of the left hand display lights up.

When the initial delay has elapsed (parameter I.d.), the upper horizontal segment switches off.
When there is no longer any milk flow, the central segment switches off and the final delay count starts

(parameter F.d.). The detachment operations start when the delay has elapsed.

During all milking stages, press the key to switch from automatic milking to manual milking and vice
versa.

Throughout milking, the right hand display indicates the duration of the milking process in minutes. The lit-up
dot indicates that milking has exceeded 10 minutes.

>> 15 minutes

Press the key (or activate the quick-lift button) to immediately stop the milking operations and start
the detachment operations.

Manual milking 4.3.2

To start milking with manual unit removal, press the key after the system has been started in
automatic milking mode:

 The dot flashing in the left hand digit of the display indicates Manual Milking.

Manual milking LED

The panel stays in the manual milking mode as long as:

 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.

Indication of milk presence 4.3.3

During milking, the left hand display indicates the current milking stage and the presence/absence of milk.
The central horizontal segment indicates if milk is going through the sensor at that time. If the milk presence
signal lasts for a period equal to the continuous flow time (parameter c.F.), the panel detects that there is an
actual continuous flow.

Maximum milking time 4.3.4

WARNING

You can envisage a maximum milking time, which can be set or disabled in the programming
menu (parameter E.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 signalled via an alarm

Detachment operation 4.4

When the initial delay has elapsed, if the panel does not detect a continuous flow of milk, the final delay
count starts (parameter F.d.).
If the continuous 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

 The pulsator stops
 the S/O Valve closes the vacuum passage
 the detachment delay time count starts (parameter d.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
 if the suction function has been activated (parameter S.L.) , when the suction delay time has elapsed

(parameter S.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.) the unit is released automatically to start a new milking session.

During the detachment stage the green LED flashes and the display features:

- the milking time in the right hand digit

- the sole lower segment in the left hand digit

Absence of continuous flow

and indication of milking time

After the detachment operation the green LED stays fixed on and the display features .
At the end of the milking operations, 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 switch to the actual detachment condition (stand­by); press the key to start a new milking session.

Stimulation 4.5

During the stimulation stage, the display features the code St and the LEDs start flashing.

On the programming menu you can define the type of stimulation (parameter t.S.) which may be:

 Forced (F.S.)
 Automatic (A.S.)
 OFF (oF) – 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 S.t.) the frequency
and pulsation ratio are gradually modified in order to reach the set values (stimulation frequency
S.F., stimulation ratio S.r.)

 AUTOMATIC STIMULATION

Stimulation starts if the function is enabled and if during milking the s/o valve does not detect a

“Continuous Flow” for a certain period of time (called “neutral time”, which can be set via parameter
n.t.).

Therefore the frequency and pulsation ratio vary gradually until reaching the values set for
stimulation (stimulation frequency S.F., stimulation ratio S.r.)
Stimulation stops when the flow meter starts detecting a “Continuous Flow” again or when the
stimulation time elapses (parameter S.t.)

 MANUAL STIMULATION

Press and hold the key for 3” during the milking cycle (with any value set for parameter t.S.)
to start the manual stimulation process: the frequency and pulsation ratio vary gradually until
reaching the values set for stimulation (stimulation frequency S.F., stimulation ratio S.r.). Stimulation
stops when the stimulation time has elapsed (parameter S.t.) and the frequency and pulsation ratio
gradually go back to the values set for milking.

NOTE

By setting stimulation ratio (parameter S.r.) on value 0, upon start of the stimulation, the
liners stay completely closed and the pulsation stops until the end of stimulation time (S.t.).

Alarm 4.6

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, code AL and the red LED start flashing on the display.

The unit removal procedures start automatically, after which code AL still appears alternately with code dt on
the display, and the red LED keeps flashing.

Press the key to reset the alarm and switch to the detachment mode (stand-by).

Quick-Lift 4.7

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 switch, 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.

Swing-Over 4.8

By activating the Swing-Over mode (Type of System dt = S.O. parameter) the ACR-Smart 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 the ACR-Smart Type
of System parameter, 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 switch, you can move arms from one side of
the milking parlour to the other.

Parameter reading 5.4

Shut-Off Solenoid Valve – E.S. and Cylinder Solenoid Valve– E.C.:

- With CV30 inversa set:

o E.S. = N.C. (atm channel)
o E.C. = N.O. (vac channel)

- With CV30 set:

o E.S. = N.C.
o E.C. = N.C.

- With CV20 set:

o E.S. = N.O.
o E.C. = N.O.

Start-up stage – IP :

- dt upon start-up the panel retracts the unit and goes into detachment mode (stand-by)

- CL upon start-up the panel releases the unit and goes into washing mode

- LP upon start-up the panel starts from the last active stage (if it is switched off during the milking
cycle it will restart in detachment mode)

Initial delay – Id :

- 10 second steps

- The parameter values must be multiplied by 10 (the dot lit-up indicates the x10 multiplication)

>> 120 seconds

Pulsation frequency in milking mode – Fr :

- LP indicates that the panel is not controlling pulsation and that it is only powering the pulsator

- The dot lit-up indicates that the value must be added to 100

>> 115ppm

6 GENERAL RECOMMENDATIONS

Positioning 6.1

Make sure that the HFS sensor is in a vertical position.

Sensitivity 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.

Problem

Causa

Solution

The unit is detached too soon

Incorrect setting of Final Delay
and/or Continuous Flow
parameters

Increase the F.d. (Final Delay)
parameter and/or decrease the
c.F. (Continuous Flow)
parameter

The unit is detached too late

Incorrect setting of Final Delay
and/or Continuous Flow
parameters

Decrease the F.d. (Final Delay)
parameter and/or increase the
c.F. (Continuous Flow)
parameter

The shut-off valve stays closed
during milking and during washing

Incorrect setting of Shut-Off
Solenoid parameter

Check that the parameter E.S. is
set on N.O. if is used a VAC
channel (eg. CV20) or on N.C. if
is used an ATM channel (eg.
CV30)
