There are two switches embedded in the decal of the front cover of the Presto. They are pictorially
labeled with a hand by the left (manual/wash) switch and an udder w/milker unit by the right (attach/
detach) switch.
To change any of the operating parameters, it is necessary to enter the setup mode. To enter into
the setup mode, while the unit is in the detached mode, push both switches at the same time. Once
in the setup mode the detacher will prompt you review data. The default value of Yes will be
flashing. Choose No by pushing the right switch. By choosing “No” you enter into the setup menu.
By choosing Yes you will enter into the review data.
After choosing No to enter the set-up mode, the screen will prompt you through the set-up options.
To scroll through the options continue to press the left switch and to change a setting press the right
switch until the desired setting is acquired. (See Set-up Table for settings and options).
Set-up should be done by a qualified technician. To maintain consistent milking
all the units on the dairy should be set-up the same.
NOTICE
Settings and 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)
