Physical Specifications
Case: Impact-resistant polysulphone with scratch-resistant Lexan ™ front label. Size 4.5” x
6.5” x 2.0”, Weight less than 16 ounces (454 grams).
FlowCell: Approved P-1700 Polysulfone materials and 304 stainless steel sensing probes.
Shape is a modified elbow, approximately 3” x 2.5” suitable for use with all 5/8” ID
milk hose.
Environment: Our proprietary enclosure is o-ring sealed against water and chemicals to permit
use in all parlors and stanchion barns.
Various stainless steel brackets and mounting plates are available to adapt the into any milking
system.
Never allow petroleum-based fly spray or other petroleum-based
products to come into contact with the control box or flow cell.
These products will damage the plastic.
Power Requirements
Power Conversion: P = power (watts), I = current (amps), V = (volts)
Amps (I) = watts (P) divided by volts (V)
Volts (V) = watts (P) divided by amps (I)
Watts (P) = amps (I) x volts (V)
Power Input:
17-30 Volts DC continuous power. The circuit board consumes about 2.5 watts. This
does not include any electric valves that may accompany the Presto. The voltage
delivered to external valves or solenoids is the same as the input voltage. Therefore,
care should be taken to be sure the supply voltage matches the specifications of the
valves or solenoids.
Hangers and mounting brackets are included but not shown. When the
Presto Detacher is installed in a parlor, stainless steel enclosures and/or
mounting brackets are ordered as needed. For the job.

Presto Control Outputs:
Cylinder output: 1 form ‘A’ (single pole N/O) solid
state contact up to 0.5A load.
Shutoff output: 1 form ‘A’ (single pole N/O) solid
state contact up to 0.5A load.
Power must be applied to the Presto for these
outputs to operate correctly.
Power Requirement Calculation:
To calculate the power requirements take the
number of units multiplied by the number of watts
required per unit. Add approximately 20% for a
safety factor. For example 18 Presto Controls
consuming 2.5 watts each, driving two 9 watt shift
valves: multiply 18 by 20.5 watts per unit equals 369
watts plus 20% safety factor equals 443 watts. This
would require a 480 watt 20 amp power supply.
Power Supply
WARNING
Power Supplies and AC Power Source
When selecting an AC power source there may be
alternatives available. When connecting the power
supply to the power source follow these step by
step procedures.
In all cases, follow local electrical codes and
safety regulations at all times. It is
recommended the power source be 220/240 volt
and that the power supply be wired to a
dedicated circuit in the incoming power panel.
There should be no additional equipment
hooked to the AC power lines feeding the
power supply. When two or more power
supplies are used in the same installation, the
negative outputs must be tied together by
adding an 14 gauge jumper wire tying the
negative DC outputs together of each power
supply. This establishes a common reference
plane, enabling communications to function.
(When using two power supplies see the
following Parlor Wiring Schematic for more
than 18 stalls)
Do not exceed the manufacturers recommended
power ratings of the power supply used.
Step 1:
Locate the power wires from the
power source that is being used.
Step 2: Firmly mount the power supply to the
mounting (din) rail supplied, in a well
ventilated, clean, dry environment not
above any heat generating equipment.
Step 3: Wire the power supply to the power source
as per the power supply manufacturer’s
recommended practices following all local
and national electrical codes.
Step 4: for the DCV output wiring, see the Presto
Power Wiring Diagram on the following
pages.
Polarity must be observed when connecting to the
Presto Control. Reversing the polarity may damage
the PC Board.
Ensure that all work is performed in accordance with
local electrical codes and that all connections and
cable ends are sealed against water intrusion.
CAUTION
Ensure that the existing power supplies are of adequate power rating.
Agricultural Instruments is not responsible for damages or losses
incurred by poorly functioning power supplies. Solid connections are
absolutely necessary to assure no electrical problems will occur.

System Operation
After starting a new system it is important to know there maybe data in the Tracker that is left over
from testing the system during manufacturing. Please disregard any information that may appear
during start-up. As milking information is collected the data will become actual on farm data.
The data is broken up by milking sessions. A milking session is defined: starting after wash with the
first cow milked and ends when the system is again changed into the wash mode. When a Tracker
Terminal is used a milking session can end anytime the operator presses the session end button on
the Tracker Terminal. Session numbers are automatically assigned and the archived sessions are
stored by date.
The following provides tips about how to understand and use the Tracker’s information. The informa-
tion is automatically created while the system runs.
System Operation & Milk Yield Calibration
Very Important: End-of-Milking and Milk Yield Calibration
Immediately after the system is started, during the first milking it is important to determine the
appropriate end of milking setting for the dairy. Do so accordingly.
End-of-Milking:
The end of milking detach flow rate and delay setting determine how wet or dry the cows are milked.
They should be adjusted according to the farmers liking. To do so, during milking, immediately after
the detacher detachers the milking unit hand strip the cows and with guidance from the farmer set
the take off flow rate and take off delay according to his liking. These settings are explained in stall
set-up section of this and other manuals.
Milk Yield Calibration:
The milk yield calibration determines how fast or slow the detachers count milk yield. (Note) It is
important that each milking station in the parlor is the same. For example the pulsation rate and
ratio, vacuum level, hose lengths and air bleeds be as close to the same as possible.
Calibrating milk yield is accomplished by comparing the total milk yield recorded by the detacher
controls against a known milk yield total like what is in the bulk tank or shipped off the farm. To do
so, under the performance reports, compare the total milk yield numbers against the known total
milk yield number. The goal is to be within 3%, if outside this range, adjust the make meter read
setting accordingly. (See Stall Control Set-up Pages)
The tips about how to analyze the data and the possible diagnostic methods listed
are only provided as management guidelines. There may be other ways to analyze
and diagnose the data. Therefore, the contents of this document are only to be
used as suggestions or general guidelines, not as the sole source of information to
guide management practices.

Network Termination
It is necessary to terminate the communications network at the last stall in the parlor and at the Presto Master
Control. Therefore, the termination switch must be switched to ON at the last stall in the parlor and at the
Presto Master Control. The remainder of the units must be turned OFF. Please see the following picture for the
switch settings.
Network Termination Switches: Both Switches
are Up for ON and down for OFF. The end stall
and Presto Master control, should be switched to
ON to terminate the network. All the rest of the
stalls should be switched to OFF.
If a Presto PC Board is ever switched out
in the parlor, be sure to switch the
settings so they are correct and match the
other units.
