Purpose
AfiFree155i is a milk meter and data-monitoring system that can function either as
part of a computerized flock management system or as a stand-alone system. Both
uses are described below.
AfiFree155i in a Computerized Flock Management System
When connected to AfiSheep/ AfiGoat, AfiFree155i performs many tasks essential to
a profitable dairy operation, such as:

Real time presentation of milk flow quantity

Supplying milk yield data to the computerized flock management system

Releasing the cluster when milk flow drops below a predetermined rate
(automatic cluster removal)

Monitoring the quantity of milk provided by a specific animal
Figure 1 (below) illustrates AfiFree 155i connected to AfiSheep/ AfiGoat.

AfiFree155i Stand-Alone System
A stand-alone system is one in which the AfiFree155i milk meters are not connected
to a flock management computer and software. In this type of system AfiFree155i
milk meters are factory programmed with a default software program, which
performs two functions:

Real time presentation of milk flow quantity

Releasing the cluster when milk flow drops below a predetermined rate
(automatic cluster removal)
Figure 2 (below) illustrates AfiFree 155i not connected to AfiSheep/ AfiGoat.
Figure 2: Terminal 155i units not connected to AfiSheep/ AfiGoat

AfiFree Wash Controller and Wash Control Valve
The parlor washing system cleans the AfiFree155i bodies via the AfiFree Wash
Controller (below) and Wash Control Valve (page 17).
The AfiFree Wash Controller
During milking the AfiFree Body operates with a continuous flow of milk through the
unit. This continuous flow does not allow the AfiFree Body to completely fill. During
the cleaning cycle it is necessary to completely fill the AfiFree Body to ensure that all
milk residues are washed out. The AfiFree Wash Controller (Figure 7) operates the
AfiFree Wash Control Valve, which controls the diaphragm to close and open the
outlet from the AfiFree Body. This allows the AfiFree Body to completely fill and
drain alternately.
Wash Controller setup is explained on page 70.
Manual Start
button
Figure 7: AfiFree Wash Controller
The AfiFree Wash Control Valve
The Wash Control Valve (Figure 8) opens and closes the Washing Diaphragm
Assembly on up to 20 AfiFree155i Bodies. This causes cleaning liquids to fill the
AfiFree Body and then drain. The cycle is repeated a number of times under the
control of the Wash Controller.
If more than 20 units are installed in the parlor, the parlor cleaning plumbing must be
divided into two or more sub-systems, each with its own Wash Control Valve.

Plug-in Wiring System
The Plug-in Wiring System is an improved alternative to wiring cables to a standard
AfiFree Connection Box. It saves time and wiring errors. Wiring connections are
made as follows:

The components of AfiFree155i connect to the Plug-in Connection Box (PICB—
see Figure 10) entirely by means of ready-wired plugs and sockets.

The power and communication cables (Figure 11) have extension tails that plug
into the PICB for each stall. Cables are available with three lengths of spacing
between extension tails (see Figure 12 and Table 3).

Valve Installation Kit for AfiFree
The valve installation kit for AfiFree contains all the parts necessary for mounting the
shut-off valve and connecting it to the AfiFree Body. It also includes a generic milk
meter bracket for distancing the AfiFree Body from the parlor wall, if required.
The valve installation kit enables mounting the shut-off valve at an angle from the
vertical, if vertical installation is not possible because of a physical limitation (such as
a low milking platform). However, vertical installation is recommended wherever
possible—see caution on page 48.
The valve installation kit is for use with the following valves:

Vacuum operated (P/N 5077001/5077018)

Air operated (P/N 5077002/5077011)

Vacuum Normally Open (NO) operated (P/N 5077017/5077015)

opened and kept open above the unit

Safely accessible for wiring and maintenance

Out of the reach of livestock

In addition to the above general guidelines, the Wash Controller location depends
on how it is activated:
▪ If the Controller is manually activated via the manual start button, it must be
mounted within easy reach of the operator, so that the button is easily
accessible
▪ If the Controller is activated remotely or automatically, it can be mounted
higher up. However, the Controller remote activation button must be mounted
within easy reach of the operator.
Wash Control Valve Positioning
Position each Wash Control Valve as follows:

Connected to the main vacuum line

So that it is convenient to install the AfiFree155i diaphragm line between it and
the AfiFree155i Bodies
Positioning Optional External Start Buttons
In installations with an External Start Button, position it according to the following
guidelines:

The button facing the milking pit

Within arm’s reach of the milking operator

Consistently throughout the parlor, so that each AfiFree unit is clearly associated
with its control button. For example, if you install a button on the right side of
the first AfiFree unit, maintain this layout in all other stalls.
May 2009
AfiFree Terminal 155i Installation Manual
29
Physical Infrastructure Requirements
The following physical infrastructure is required for operation of AfiFree155i:

Milk Line

Vacuum Line

Washline
Milk Line
A stainless steel milk line is required to transport the milk to the milk tank.
Vacuum Line
A separate OD 50 mm PVC vacuum line is required in the parlor for the operation of
the AfiFree Wash Valve. See pages 55–57 for full details of installation.
Washline
A separate OD 50 mm pipe is required in the parlor to wash the AfiFree155i bodies. It
must be connected to a water source, a washing sink, and a drain.
Physical Interfaces to Components
The AfiFree Body is usually attached to the Generic Milk Meter Bracket which is
itself welded to the stainless steel side of the milking curb.
Terminal 155i is usually attached to a metal plate that is itself fixed to a pipe, wall, or
cabinet.
The AfiFree Connection Box should be secured to the metal-work above the milking
point.
The Wash Controller can be attached to a suitable surface by means of the mounting
plate (P/N 4088016), or directly screwed to a suitable surface.
The External Start Button can be attached to a 5 cm (2‖) diameter vertical column
using the clamps provided, or attached to any convenient surface.
Electrical Requirements
If installed incorrectly, the power supply can damage equipment and
injure users. The power supply system must be installed by a qualified
electrician.
W AR NI NG
30
The installation must meet national safety codes and must make use of
suitable circuit breakers.
‎Chapter 2 Site Preparation Requirements
P/N 9040322
Electrical requirements has the following parts:

Power Supply Requirements (page 31)

Wiring Requirements (page 32)

Grounding Requirements (page 32)
Power Supply Requirements
For a basic parlor installation (AfiFree155i milk meters and cluster removal pistons,
without additional outputs), the power supply must meet the following requirements:

24 ± 2.4 VAC power supply, 50 VA to each milking point

24 ± 2.4 VAC power supply, 75 VA to the wash controller
Table 5 specifies the power requirements for installations with different quantities of
AfiFree155i milk meters.
SAE recommends the use of a separate transformer and separate 24 VAC wiring for
each side of the milking parlor, for two reasons:
 If one transformer fails, the second side of the parlor remains operational

Troubleshooting is easier
In installations using the Plug-in Wiring System, AfiMilk recommends using one
1,000 VA transformer for up to 18 stalls.

The power cable is 8 AWG (16 mm ). Therefore, no more than 18 milking
points may be connected to one length of power cable. The power cable
must thus be cut into lengths with no more than 18 extension tails each.
Where there are more than 18 milking points, use more than one length of
power cable.
AfiMilk recommends using one 1,000 VA transformer for up to 18 stalls.

Position the vacuum line (Item 1) above the milk line. Maximum length of the
pipe (Item 2) is 50 cm (19‖).
2.
Secure the vacuum line to the wall (or to brackets supporting the milk line) with
pipe clamps (item 8). Place a pipe clamp at each milking station (to prevent the
line from sagging). The vacuum line should be positioned with an angle of 1.52.0 toward the drain valve (Item 6 in Detail D).
3.
Drill 11 mm holes in the vacuum line (Detail C), slightly off center from each
AfiFree Body. Ensure that the holes are in a uniform position on the line and
relative to the AfiFree Body.
4.
Press the nipple (Item 3) into the 11 mm holes in the vacuum line.
5.
While holding the black bushing around the nipple, pull the hard plastic portion
out. This locks the nipple in place and seals the hole.
6.
Connect the pipe (Item 2) between the diaphragm on the AfiFree Body and the
nipple on the vacuum pipe.
7.
Assemble and mount the vacuum line drain (Items 4, 5, 6, and 7, Detail D) at the
lowest point in the vacuum line, so that when the drain valve (Item 7) is open,
fluids drain from the vacuum line to the floor.

Setting Up the Wash Controller
NO T E
For parlors where the washing process is controlled by AfiWash, see
AfiWash Installation manual P/N 9040646.
This section contains the following parts:

Wash Controller Principles of Operation (below)

Wash Controller Configuration (page 70)
Wash Controller Principles of Operation
In milking mode, the AfiFree Body allows milk to flow through it freely. In cleaning
mode, cleaning fluids must completely fill the AfiFree Body to enable thorough
cleaning.
In cleaning mode, during system wash, cleaning liquid is supplied by the parlor wash
system. The AfiFree Wash Controller alternately turns the Wash Control Valve(s) on
and off.
The Wash Control Valve opens and closes the washing diaphragm of each AfiFree
Body connected to it, allowing the AfiFree Body to repeatedly fill up with washing
liquid and then to empty.
One Wash Controller controls one or two Wash Control Valves, opening and closing
both Wash Control Valves simultaneously.
One Wash Control Valve controls up to 20 AfiFree155i bodies (see Figure 37).
Figure 37: AfiFree Cleaning System
During the system wash, the Wash Controller opens and closes the Wash Control
Valve(s) according to a preset cycle, until the system wash is complete. The cycle is
set, after parlor installation, according to the Wash Controller Configuration
procedure, below.
70
‎Chapter 4 System Configuration
P/N 9040322
The Wash Controller has two modes of operation:

Automatic mode - the main parlor wash system activates and shuts down the
Wash Controller.

Manual mode - the Wash Controller is activated by a manual control button, and
is turned off after a predefined time interval.
Wash Controller Configuration

Check the current wash cycle duration by chemical testing and milk sampling. If the
results are below standard, extend the wash cycle by increasing the Wash Duration
parameter value.
Testing AfiFree155i Performance
AfiFree155i milk meters must be tested before beginning normal operation. If
AfiFree155i milk meters have been installed as part of a system including antennas,
parlor controls etc., the following tests are performed as part of the system tests.
1.
Check the power supply.
AfiFree155i milk meters will not operate at less than 21.6 VAC. Voltage in
excess of 26.4 VAC will cause damage to the AfiFree155i milk meters.
2.
Check the vacuum supply.
The vacuum pressure must be between 36-38 kPa.
3.
Check that the Wash Controller has been set up to local requirements.
4.
To verify that there is vacuum at all the washing diaphragms, remove the vacuum
line connection to the AfiFree155 body and check vacuum.
5.
Perform a washing cycle:
a.
Verify that there are no leaks in the system.
b.
Verify that the washing diaphragm opens and closes according to the timing
set.
c.
Verify that the shut-off valves on the long milk tube operate.
d.
Check that all AfiFree155 bodies are filled with water up to the tip of the
electrodes and that the inside of the cover is cleaned by the turbulence. If the
AfiFree155 bodies are not filled with water, reset the washing parameters
(see Wash Controller Configuration, page 71).
e.
Verify that all AfiFree155 bodies are clean and are fully drained after the
washing cycle.

If the AfiFree155 bodies are not clean reset the washing parameters as in
step d above.

If the AfiFree155 bodies are not completely drained adjust the Time Off
parameter.

option is available only under AfiSheep/ AfiGoat.
At the start of a milking, when all of the milk meters are in cleaning mode, press
simultaneously "Group Nº " +"2"on one of the milk meters. All Milk Meters on the
same side will change mode from Cleaning to Stand By.
At the end of a milking, press simultaneously "Group Nº "+"8" on one of the milk
meters. All Milk Meters on the same side will change mode from Removal to
Cleaning.
May 2009
AfiFree Terminal 155i Installation Manual
77
Cluster Clearance
(either under AfiSheep/ AfiGoat or in a standalone configuration)
Set parameter Cc to allow cluster clearance.
CC parameter is the delay time desired (in seconds), between cluster removal and the
lowering of the cluster.
After setting this parameter, the milk meter is timed to lower the cluster (at the designated
delay time) after cluster removal. After an animal has been milked and the cluster removed,
the cluster remains in the lower position to allow easy preparation of the animals.
Raising or Lowering Clusters
(either under AfiSheep/ AfiGoat or in a standalone configuration)
In removal mode, to raise or lower a cluster without initiating milking, hold down the
group number button
and then press 1.
Stimulation
(either under AfiSheep/ AfiGoat or in a standalone configuration)
A rapid pulsation at the beginning of milking helps to stimulate milk let-down.
Three parameters control the stimulation function:

Stimulation Duration (STD)

Stimulation Pulsation Frequency (STF)

Stimulation Pulsation Ratio (SR)
To allow automatic stimulation by code from AfiSheep/ AfiGoat, set Parameter AS to
1(ON).
For Manual Activation Stimulation, press "Code"+"9" combination (only in removal
for next milking only).
For Manual Stop/Canceling Stimulation, press "Code"+"6" combination.
Milk Diversion
An extra milk line must be installed to carry the diverted milk. As well, a diversion
valve must be installed near the milk outlet of the milk meter. The circuit is normally
open. Use the Strip output to control a diversion valve. This function diverts milk
from the main milk line into a secondary milk line. Milk can be diverted
automatically, or manually, as needed.
To allow this feature with pulsation control set parameter IOC to 2.
To allow this feature with Back Flush set parameter IOC to 3.
If this feature is used, the Strip feature cannot be used.
Diverting Milk Manually
Pressing "Code"+"0" diverts milk from the milk meter into the secondary line.
78
‎Chapter 4 System Configuration
P/N 9040322
Pressing "Code"+"8" returns the milk flow to the main milk line.
This feature is useful if a milker notices that here is some blood in the milk.
Automatic Milk Diversion
This feature automatically diverts milk from an animal that has been identified with a
health code. The duration of the milk diversion depends on the code assigned to the
animal:

If the animal has assigned a Dump Milk Operation code, milk is diverted
throughout the milking.

If the animal has assigned a Dump First Milk Operation code (DPM parameter),
only first milk is diverted.
Milk Remainder
(either under AfiSheep/ AfiGoat or in a standalone configuration)
A certain amount of milk remains in the bend of the tube after the animal is milked.
When milking resumes, this milk passes through the AfiFree155 body too quickly to
be registered. The Milk Remainder parameter compensates by automatically adding a
set amount to the quantity of milk recorded for each animal.
Sweep
(either under AfiSheep/ AfiGoat or in a standalone configuration)
AfiFree 155i milk meters can be set to remove milk remaining in the milking tube
after each milking by performing a sweep. The sweep pulse duration, number of
sweep pulses, and sweep delay can be set individually in three parameters with those
names (see Table 19).
Viewing software version
(either under AfiSheep/ AfiGoat or in a standalone configuration)
These options enable you to view the software versions, as follows;

Terminal 155i: Press buttons "F"+"0" simultaneously.

Milk Meter: Press buttons "Stall number"+"0" simultaneously.
Setting Parameters in AfiSheep/ AfiGoat
Group Retrieval
If you want to raise or lower clusters in groups, you need to set two parameters in the
AfiSheep/ AfiGoat real-time window:
Set Lowering Clusters in Batches – Number of Milk Meters per Batch to a value
of at least 1.

Auto Program
Auto Program is a parameter set in AfiSheep/ AfiGoat that determines whether
AfiMen automatically loads parameter values (except for the G parameter) to milk
flow indicators. When Auto Program is enabled AfiMen functions as follows:
1.
When communication is established with the milk meters, AfiMen compares the
parameter values in each milk meter with those set in AfiSheep/AfiGoat (except
for the G parameter).
2.
If any milk meter has a parameter with a value different from the value in
AfiSheep/AfiGoat, then AfiMen overwrites the value in the milk meters with the
value in AfiSheep/AfiGoat (except for the G parameter).
This option is useful when replacing a Terminal 155i or installing a new one.
To enable Auto Program:
1.
Open AfiSheep or AfiGoat.
The AfiSheep or AfiGoat main window appears.
2.
In the AfiSheep or AfiGoat main window, select Parameters from the Tools
menu.

Calculating and Setting the G Parameter
An AfiFree 155i milk meter provides an indication of volume of milk produced from
the associated stall. However, variations in placement of the milking and vacuum
lines and other factors in the parlor may cause a difference between the volume
recorded by the AfiFree 155i milk meter and the actual volume produced. To
compensate for this difference AfiFree 155i uses the G parameter.
There are two ways of calculating and setting the G parameter:

For each milk meter individually—see Calculating and Setting G for an
Individual Milk Meter (below)

For all milk meters together—see Calculating and Setting G for All Milk Meters
(below)
Calculating and Setting G for an Individual Milk Meter
1. Weight the milk from the milk meter (= the Actual Amount).
2.
Calculate G for the milk meter as follows:
Actual Amount
Amount recorded by
AfiFree155i
3.
X
100
=
―G‖ value
Set the G parameter for the milk meter.
Calculating and Setting G for All Milk Meters
1. Weigh all the milk from all the milk meters in one milking session (= the Actual
Amount).
2.
Calculate G for the milk meter as follows:
Actual Amount
Amount recorded by
AfiFree155i
3.
X
100
=
―G‖ value
Set the G parameter for all milk meters as explained in Setting Parameter Values
for all AfiFree 155i Milk Meters, page 81.
Setting Parameter Values for all AfiFree 155i Milk Meters
There are two steps to setting the parameter values for all AfiFree 155i milk meters:

Entering a Parameter Value in AfiSheep/AfiGoat (below)

Uploading Parameter Values from AfiSheep/AfiGoat to All the Milk Meters
(page 82)
Entering a Parameter Value in AfiSheep/AfiGoat

Appendix B Milking System Cleaning
Guidelines
This appendix provides guidelines and recommendations for cleaning the milking
systems. It contains the following sections:

Cleaning Recommendations (below)

Performing an Acid Wash (page 120)
 Always comply strictly with the instructions of the chemical manufacturers.
Failure to comply with instructions can cause injury and damage to
equipment.
 Use gloves and protective goggles when working with chemical detergents.
W AR NI NG
 Avoid mixing active detergents and acids in the same container.
 Butyl Glycol or Butyl Cellusolve detergent in excess of 10% concentration
may damage plastic components of the system. SAE Afikim recommends
cleaning fluids with a maximum concentration of 10% Butyl Glycol or Butyl
Cellusolve.
C AUT IO N
 Follow all of the manufacturers’ recommendations, including:
concentrations, temperatures, and cleaning-cycle times. Excessive use of
chemicals may damage the AfiFree155 body.
 Leaving detergent inside the AfiFree155 body may damage its
components.
 Avoid contact of pesticide materials with the exterior of the AfiFree155
body and Terminal 155i.
 Clean the AfiFree155 body and Terminal 155i’s exterior with a moist cloth,
without detergent.
Cleaning Recommendations
Cleaning recommendations has the following parts:

Chemical Dispensing Pumps (page 119)

Vacuum Pump (page 119)

Liquid Volume (page 119)

Temperature and Cycle (page 119)

Cleaning Exterior Surfaces (page 120)
NO T E
118
To prevent deterioration in accuracy due to limestone residue on the
electrodes of the AfiFree155 body, perform three acid wash cycles every
week.
‎Appendix B Milking System Cleaning Guidelines
P/N 9040322
Chemical Dispensing Pumps
To achieve accurate detergent dispensing, we recommend using chemical dispensing
pumps.
Vacuum Pump

The vacuum pump must operate throughout the cleaning cycle. A temporary stop
of the vacuum pump while the sink is being filled can cause milk and cleaning
fluid to seep out between the lid and the AfiFree155 body.

The clusters must be connected to the jetters.
Liquid Volume
During every stage of cleaning, there must be sufficient liquid to ―flood‖ the milk
chamber of the AfiFree155i bodies.
The amount of liquid required per milking point varies between 6–8 liters, according
to:

Parlor configuration

Length and diameter of milk lines

Volume of the receiving vessels
Factors requiring additional liquid for cleaning:

Double size milk line is installed in the parlor

Milk tank is far from the parlor
Temperature and Cycle
There are various cleaning systems and procedures in use in milking parlors.
Nevertheless, the following rules must be followed for all the procedures and
detergents in use.
Initial cleaning in an open circuit: All residual milk must be rinsed into a drain
using lukewarm water. The temperature of the water should be approximately body
temperature.

Water too cold will cause the milk fats to solidify on the surfaces, and be difficult
to remove.

Water too hot will cause the milk fats to bake onto the surfaces, and be difficult
to remove.
Cleaning with hot soapy water: circulate hot water with detergent in the system.

Use a basic detergent additive (Ph=13)

Entry water: minimum 70°C (158°F)

Returning water: minimum 55°C (131°F)
The milking system must be warmed up by passing hot water through the system.
May 2009
AfiFree Terminal 155i Installation Manual
119
After warming up, the milking system must be brought into a closed circulation setup,
detergent added, and the hot water and detergent circulated for 10-12 minutes.
After being circulated in the milking system, the hot water and detergent must be
drained away.
Rinsing with cold water: the milking system must be rinsed with cold water in an
open circuit to remove all traces of detergent.
Cleaning Exterior Surfaces
C AUT IO N
Detergents are destructive. Do not use any kind of detergent on the
AfiFree155 body.
Moisten a soft cloth with water and gently rub the surfaces of the AfiFree155 bodies.
Performing an Acid Wash
Perform an acid wash three times a week, or more frequently when necessary. The
acid wash does not replace the daily cleaning routine.
 There are some cleaning solutions available that remove both milk
residues and hard water salts.
NO T E
 Follow all of the manufacturers’ recommendations, including:
concentrations, temperatures, and cleaning-cycle times. Excessive
use of chemicals may damage the AfiFree155i bodies.
To perform an acid wash (after performing a regular cleaning cycle with hot water
and detergent):
1.
Rinse the detergent solution out of the system with cold water.
2.
Circulate hot water and phosphoric and/or sulfuric acid for 10–12 minutes and
drain:
▪ Entry liquid: 70°C [158°F], minimum
▪ Returning liquid: 55°C [131°F], minimum
3.
120
Rinse the system with cold water.
