Introduction
Chapter 1 Introduction
Welcome to the Legacy 2000, the new genera-
tion of chemical control systems. The Legacy
2000 controls up to two different products,
automatically, manually, or under external control.
New technology allows the Legacy 2000 console to
communicate with remotely mounted control modules
through a single cable. These modules in turn control
and monitor the valves, sensors, pumps, etc. of the
system. Control modules can be “tapped” into the main
cable at any point, which means that they can be
mounted anywhere on the machine, near the compo-
nents that they are associated with. Using one cable to
connect the modules to the control console in the cab
eliminates the “rat’s nest” of cables running into the
cab from all over the vehicle.
The opeating program is contained on an SRAM card
inserted into the side of the console making it easy to
change or upgrade your program. (CAUTION: To
prevent damage to the program or the SRAM
Card, the console must be powered down while
inserting or removing the card)
This User Guide provides you with the basic
information needed to set up and operate the
MID-TECH®Legacy 2000 control system.
Actual procedures may vary, depending on the
configuration of your system.
When you see "Mitch", he is pointing out special
information that you should be aware of, regarding
safety, preventing equipment damage, an easier way to
perform an operation, etc..
A brief description of the console control buttons and
the icons that appear on the display are described at the
edges of the pages in Chapter 3 (Operate functions)
and Chapter 4 (Setup Functions)
The topics are presented with the most often used
information located toward the front of the guide.

START-UP SEQUENCE
The Legacy system monitors the accessory
position of the ignition switch. When the
ignition switch is turned on the Legacy system
begins its start-up sequence. The console will alternate
between the two screens shown in Fig. 2-1 while it is
performing its system check.
During the system check each module (Console, PSM,
SSM, PCM) is verified to make sure nothing has
changed since the system was last powered up. If any
descrepancies are found the console asks for user
input to verify the module information.
Once the system check is complete the screens shown
in Fig. 2- 2 appear and three beeps are heard.
At this point the operator can:
•Press the Setup button ( ) to make any necessary
system setup changes to the Legacy system
•Press the Operate button ( ) to go directly to the
operate mode.

from
the “Main Setup”screen (Fig. 4-2) to enter the
appropriate setup function. (We are using “Liquid
Product 1”for this illustration.) This displays the
screens shown in Fig. 4-3. Which indicates that you are
setting Preset Rate “A”, it is being measured in
Gallons per Acre and the current value is 10.0 GPA.
The symbol indicates that you can use the and
buttons to select which digit of the Rate Value is
changed (The flashing digit). The symbol indicates
that you can use the and buttons to adjust the
value of the flashing digit. When the desired value has
been selected press the button to register the value
and advance to the Rate “B” preset screen. This
continues until all desired Preset Rates are set.
When setting the “Preset Rates”the button can be
used to move the decimal point. Each time is
pressed the decimal point moves one position to the
left until it disappears from the screen. The next press
of the button brings the decimal point back at the right
side of the screen.
If a flowmeter is used to control or monitor the
selected product continue to the next section. If only a

Flowmeter Cal. # Set
From the screen shown in Fig. 4-4 the initial
flowmeter calibration number can be set using
the same method as that for the Preset Rates
(Use and to select the digit and and to
adjust the value of the digit). Use the button to

. If a pressure sensor is also used with this product
the next screen is Fig. 4-5. Otherwise the display exits
to the “Main Setup”screen (Fig. 4-2).
The flowmeter calibration number represents “Pulses/
Gallon”for US units and “Pulses/Liter”for metric
units. The flowmeter usually has a tag indicating the
“Initial Calibration Number”in Pulses/Gallon.
NOTE: Before starting actual application, a field test,
using water, should be done to verify the accuracy of
the Cal. #, and any necessary adjustments made. Use
the following formula to calculate a new Cal. #, if
necessary:
Pressure Based Setup
If a pressure sensor is used to control or monitor the
selected product, the low and high pressure values
of the sensor must be calibrated to match those of a
manual pressure gauge installed near the pressure
transducer. This process starts with the “Zero Set
Point”screen (Fig. 4-5).
From this screen we are setting the “Zero Pressure
Reference Point”for the console.

•The product pump must be turned OFF.
•At least one boom section of the associated swath must
be turned on to ensure that there is no pressure in the
boom. (It may be necessary to loosen a diaphragm check
valve to relieve all pressure.)
•Press and hold until the console beeps. The “Zero
Reference Point”is now set.
You should now see the screen sequence shown in Fig.
4-6, from which we set the “High Pressure Reference
Point”.
•Be sure to tighten any check valve loosened previously.
•The booms must be off (Master Switch OFF).
•The product pump must be turned ON.
•Slowly increase the engine RPM to adjust the pressure
reading on the manual pressure gauge to a maximum no
higher than the sensor’s specification.
•Set the pressure reading on the console to match that on
the manual pressure gauge.
•Use the and buttons to select the digit of the
display to be changed.
•Use the and buttons to adjust the selected
digit.
•When the console display has been set to match
the pressure gauge press .
NOTE: When using dual pressure sensors, both
sensors use the same Hi/Low pressure values.
The display reverts to the “Main Setup”screen (Fig. 4-
2) unless you are using a pressure sensor to control
product flow. In this case the screen shown in Fig 4-7
appears. This screen allows the operator to set the
“Nozzle Constant”into the console. The constant
should be taken from a nozzle chart for the particular
set of nozzles that you are using. Use the 10 MPH/30
PSI value (10KPH/2.0 Bar) for metric operation).
