Introduction
Your new MT-9000 system is a high-performance controller,
designed for superior control of agricultural product
applications while providing easy-to-use features to help you
manage your farming operation efficiently. From the large,
easy-to-read display and controls to the Utilities Software
provided, the system is designed with the operator in mind.
Some of the built-in features are described in the following
paragraphs.
FLEXIBILITY
The MT-9000 can be easily configured to control liquid, NH3
or dry material applicators, and will display the appropriate
units as well as the data so it is easy to see what is being
displayed.
The MT-9000 can control your liquid applicator in three ways.
“Flow Only” uses the flowmeter feedback only, and can be
used with or without a pressure sensor. “Pressure Only” uses
feedback from the pressure sensor only, and can be used
without a flowmeter. “Hybrid” uses feedback from both
the flowmeter and the pressure sensor to provide optimal
control response and accuracy. Operation in either “Pressure
Only” or “Hybrid” control mode requires installation of a
pressure sensor and proper calibration for the nozzles you
are using.
THREE INDEPENDENT RATE SETTINGS
The system provides three application rate settings with
clearly marked buttons to choose the desired rate. The three
rates can be set up in two ways: If the same nozzles are always
used, three selectable rates can be set up for varying field
conditions. If three different sets of quick-change nozzles
are used, each of the three rates can be set up for a different
set of nozzles. This will save time when changing nozzles,
because the console will not need re-calibration to work
properly in any of the control modes.
ALARM WITH EASY SET UP AND CONTROL
An internal alarm is provided to alert the operator to error
conditions. The alarm is factory-set to turn on if the actual
application rate is more than +/— 10% from the target rate,
and can easily be turned to a lower volume, or turned off
entirely, by simply using the toggle switch on the back of the
console. The alarm can also be set to turn on if the tank level
is below a preset minimum.
FLASH PROGRAM MEMORY
The MT-9000 program resides in flash memory, allowing
simple field upgrades to the software, using the provided
software utilities and downloadable files, as more features
are developed and added.
RS232 SERIAL INTERFACE
The MT-9000 serial interface allows the MT-9000 to be
linked to most desktop, laptop or palmtop computers.
This serial link can be used to calibrate or reprogram the
console using the provided software utilities package, or
it can be used with appropriate software such as Farm Works®
SiteMate to accomplish variable rate application (VRA), or as
a data logger to download all of the accumulated data and
calibration parameters to the PC at intervals commanded by
the PC program.
SOFTWARE UTILITIES
A compact disc with Utility Software is provided with each
system. If you have access to a PC with CD drive, this
software can be easily loaded on the PC. The Utility Software
includes a calibration “wizard” that directs the operator
through the MT-9000 calibration process and automatically
sets up calibration for various types of systems. If the PC is
connected to the MT-9000, the calibration parameters can
be downloaded directly to the MT-9000, or the calibration
settings can be printed out and entered into the MT-9000
manually. The calibration settings can be stored as files so
the MT-9000 can be quickly re-configured if it is used with
different applicators. If the PC is connected to the MT-9000,
the Utility Software also provides the ability to download and
store all of the data collected by the MT-9000, or to reprogram
the MT-9000 with program upgrade files provided by Micro-
Trak via e-mail (or on floppy disk).

Tools Needed to Install MT-9000
• Screwdrivers • Pliers
• Set of Wrenches • Wire Cutter
• Electric Drill and Bits • Hacksaw
• 12-Volt Test Light • Center Punch
• Bench Vise • Hammer
Installation
Mounting the Display Console
Select a mounting location which seems most workable,
and that best fits your needs. It should be convenient to
reach and highly visible to the operator. DO NOT INSTALL
IN A POSITION THAT OBSTRUCTS THE VIEW OF THE ROAD
OR WORK AREA. Whenever possible, avoid locations that
expose the console to direct sunlight, high temperature,
strong chemicals or rain.
Place the mounting bracket in the selected location, mark
holes, drill 1/4” (7mm) holes and mount bracket with bolts,
lockwashers and nuts provided. (If bolts are not practical, use
self-tapping screws.) See Illustration 1.
Place the console in the “U” bracket and install the console
knobs through the bracket, placing a rubber washer over the
threaded stud. Position console to proper viewing angle and
tighten the knobs securely. See Illustration 1.
Illustration 1

Electrical Installation
The MT-9000 Series must be connected to a 12-volt DC elec-
trical system. Power is connected directly to the battery. The
MT-9000 Series has an ON/OFF switch on the console to turn
the power off when the system is not being used.
Locate the power cable harness and connect to the
mating connector on the console. Connect the blue
chassis ground wire from the quick-disconnect tab on
the back of the console, to a good frame ground. See
Illustration 2. Make sure there is good metal-to-metal contact.
Route the power cable from the console to the battery. Cut
excess length. In routing cable to battery, avoid areas where
the cable may be subjected to abrasion or excessive heat.
Install the in-line fuse provided with the kit as illustrated,
on the white wire, to protect the circuit. Connect the WHITE
wire (hot) to the positive battery terminal. Attach the BLACK
wire (ground) to a screw or bolt on the equipment frame.
See Illustration 2. Be sure there is good metal-to-metal con-
tact.
Your MT-9000 Series is equipped with an electronic memory
which does not require a constant supply of power to retain
daily totals or calibration values. The advantage with this
type of memory is that it conserves battery power and will
not discharge the vehicle’s battery when equipment is not
in use.
Illustration 2
NOTE: For Negative Ground Systems Only.

10
Magnets
Please read the following information about magnet
spacing and polarity.
The number of magnets that must be used depends on
the size of your tire and where you mount the sensor. On
tractor or implement wheels the general rule of thumb is one
magnet for each wheel bolt (minimum of two, and always an
even number). For drive shafts or small wheels (ATV’s), two
magnets are usually adequate.
Some installations may require that more than two magnets
be installed. To determine the number of magnets required,
measure the distance traveled of one revolution of the
sensor equipped wheel in inches (centimeters).
See the following tables to find the minimum number of
magnets required (always an even number)
Illustration 3A
Installation Note: The console provides one connection point
for the speed sensor.
Please Note: If you have purchased a Vansco radar or other
radar or GPS speed sensor, disregard the following section
on magnetic speed sensors and install the Vansco or other
radar as described in the instructions included with the unit.
You will need an adapter cable to connect to radar or GPS
Speed Sensor.
Illustration 3B
Installation (cont)
Speed Sensor Installation
Locations where the sensor may be installed:
1. Non-driven wheel on tractor, vehicle or implement. This is
less susceptible to errors resulting from wheel slip.
2. Tractor, vehicle or planter drive shaft. This type of
mounting is recommended for trucks, four-wheel drive
tractors or other equipment that has poor or no access
to a non-driven wheel. See Appendix A for magnetic
speed sensor installation details for various types of
wheels or drive shaft.

NOTE: Magnets may be attached
mechanically or adhered with
epoxy or other high quality
adhesive. When using adhesive,
thoroughly clean the area of dirt
and oil.
Locate the following parts:
• Speed sensor cable (green body)
• Mounting “L” bracket
• Magnets
• Cable ties
The magnets provided by Micro-Trak are marked with a
punched dashed line on the SOUTH pole side of the magnet.
See Illustration 3A.
Always use an even number of magnets, and always alternate
the polarities of the magnets as you go around the wheel
hub or drive shaft.
To install, mount the first magnet with the SOUTH pole side
(dashed line) facing toward the hub or shaft. Mount the
second magnet with the NORTH pole side facing toward the
hub or shaft. See Illustration 3B.
For proper operation, the magnets must be evenly spaced
around the wheel or drive shaft. The magnets must be at
least 1” apart. See Illustration 3C.

Installation (cont)
Attaching Speed Sensor
The magnets are attached to a wheel hub or drive shaft and
the speed sensor is mounted directly over the magnet. When
the wheel or drive shaft begins turning, a speed impulse
is sent to the MT-9000 Series console every time a magnet
passes by the tip of the speed sensor. For the speed sensor
to operate properly, the spacing between the magnets and
the tip of the sensor must always remain constant. Before
permanently mounting any parts, be sure that the location
you have selected will meet the following requirements.

or call Micro-Trak Systems, Inc. at 1-800-328-9613.
Astro II GPS Speed Sensor
Connecting the Speed Sensor Cable
The speed sensor cable has a GREEN sensor body and mates
with the cable having a YELLOW cable tie near the 3-pin M/P
connector. Make certain that you install the correct sensor
cable. The speed sensor and the flow sensor are identical,
but must be connected to the proper harness connector.
The speed sensor always connects to the harness lead with
the YELLOW tie and flow sensor always connects to the main
harness lead with the GREEN tie. REFER TO WIRING DIAGRAM
ON PAGE 18.
Speed Sensor Options
In addition to the standard Hall-effect magnetic speed
sensor, the MT-9000 may be interfaced with a variety of other
speed sensing equipment. Several options are listed below.
ASTROSERIESOROTHERGPSSPEEDSENSORINTERFACES
The MT-9000 may also be used with most GPS speed sensors
that output a pulsed signal, such as the Micro-Trak Astro
II and 5, SkyTrak or Dickey-John GPS speed sensors. An
adapter cable may be required.
VANSCO™RADAR SPEED SENSOR
The Vansco radar speed sensor uses a microwave (radar)
signal to deliver a reliable, accurate speed signal for electronic
equipment. It features state-of-the-art electronic design/
manufacturing, rugged aluminum housing and complete
testing and certification.
RADAR INTERFACE
The MT-9000 may also be interfaced with most popular
radar ground speed sensors. An adapter cable is required for
proper interface.
SEE APPENDIX H FOR LIST OF ADAPTER CABLES FOR RADAR.
GPS SPEED SENSOR INTERFACE
The MT-9000 may also be used with most GPS speed sensors
that output a pulsed signal, such as SkyTrak or Dickey-John

Illustration 10
With oversized pumps, it may be necessary to install a
range adjust valve. The range adjust valve will reduce the
pumps output to the rest of the system. Adjustment of this
valve is covered in the Pre-Field Checkout on page 31. See
Illustration 8.
Installing Pressure Sensor
If you are using a pressure sensor, it must be installed before
the boom shut-off valves in your plumbing configuration.
Install the pressure sensor in the main sprayer line as close
to the boom shut-off valves as possible. Locate black and
white wires (tied back) at the end of the Flow/Servo harness.
Connect to corresponding wires on pressure sensor. See
Illustration 9. See the instruction sheet included with the
#01555 Pressure Sensor Kit.
NOTE: The console display area for pressure will be blank
until initial nulling is complete.
To null the pressure sensor:
1. Place the AUTO/MAN/HOLD switch in HOLD.
2. Turn the rotary dial to FLOW RATE.
3. Press both the Test button and the “—” switch.
NOTE: The pressure offset can be re-nulled if a new sensor
is installed, but the display cannot be blanked once it is
set.
Servo, Throttling Valves
The servo valve installs in an unrestricted return line to the
inlet of the pump or directly into the tank. DO NOT install the
servo valve closer than 12” to the flowmeter. The servo valve
has a flow direction decal on it. Make certain that the actual
flow direction matches the decal on the servo valve. Do not
install the servo valve in the agitation line. Slow response
time and marginal operation may result. The return line
should tee from the main line just after the throttling valve.
See Illustration 10. The throttling valve is used to limit the
output (set maximum output) of the pump to the flowmeter
and servo valve. The throttling valve is adjusted to put
the servo valve in its optimal operating range. Please refer
to Pre-Field System Checkout for proper valve adjustment
procedure.
The servo valve connects directly to the main harness 3-pin
W/P cable lead. If more length is required, use a 3-pin W/P
extension cable of the appropriate length. If using a different
12-volt control valve, please refer to “Servo Type” in the
Special Calibration section, starting on page 20.
NOTE: The servo valve may be installed in the main spray
line. For in-line use, you will need to calibrate for inline
(see Special Calibration starting on page 20. Failure to set
for inline will result in backwards operation of the servo
valve.

Whenever all the boom control switches are turned off, or
when HOLD is selected, the electric relief valve should be
open. DO NOT install the relief valve closer than 12” to
the flowmeter. With the relief valve installed, connect one
terminal to ground and connect the other terminal on the
relief valve to the violet wire on the Flow/Servo cable harness
(no tie). DO NOT connect the relief valve cable to one of the
boom shut-off leads.
Illustration 11
Boom Shut-off Valves
Plumb boom valves with flow-through port as shown. Boom
valves of differing designs may require a “T” fitting. Make
certain to use adequately sized plumbing lines to avoid
excessive pressure drops. DO NOT install the shut-off valves
closer than 12” to the flowmeter.
Locate the boom shut-off harness. The boom wires are color-
coded. (IF valves have wires, crimp terminals on those wires.)
Attach the cables to the terminals on the boom valves.
Attach a ground terminal to each valve. If valves operate
backwards, reverse connections. Apply silicone grease to the
terminal connections to help prevent corrosion and insure
a good electrical connection. NOTE: The wire for Boom
6 is the BLUE wire tied back at the end of the Flow/Servo
harness.
IMPORTANT: SEE WIRING DIAGRAM ON PAGE 18.
NOTE: A basic configuration for 2-, 3- and 4-wire ball valves
is shown in Appendix B (in the back of this manual).

Calibration
20
In this section, we will help you calibrate your system
specifically for your liquid application needs. Follow these
procedures carefully to make sure you are properly prepared
before you get to the field.
A Software Utility package is provided with each system. If you
have access to a PC with CD drive, this software can be easily
loaded on the PC. The Utility Software includes a calibration
“wizard” that directs the operator through the MT-9000
calibration process and automatically sets up calibration
for various types of systems. If the PC is connected to the
MT-9000, the calibration parameters can be downloaded
directly to the MT-9000, or the calibration settings can be
printed out and entered into the MT-9000 manually. If the
PC is connected to the MT-9000, the Utility Software also
provides the ability to download and store all of the data
collected by the MT-9000, or to reprogram the MT-9000 with
program upgrade files provided by Micro-Trak via e-mail (or
Compact Disk). See the Compact Disc you received with your
MT-9000 Series Automatic Rate Controller.
“Special” Calibration
We’ll begin with the “Special” Calibration section. You will
need to go to “Special” Calibration anytime your system
uses a modified set-up. Modifications include: Metric or Turf
measurement, Servo type other than a Micro-Trak servo
valve, in-line versus by-pass plumbing, ball valves versus
solenoid valves. If your system does not use any of these
modifications, skip “Special” Calibration and go to Standard
Liquid Calibration on pages 24-30.
Entering “Special” Calibration Values
The MT-9000 Series has a number of control functions which
are preset at the factory (See Factory Calibration Chart on
page 24). In some cases, however, it may be necessary to
change one or more of these settings to enhance performance
or meet special operational requirements. To make these
changes, you need to enter Special Calibration. To enter
Special Calibration, proceed as follows:
1. Turn the power switch OFF.
2. Place the AUTO/MAN/HOLD switch in the HOLD position
and turn the rotary dial to the SPEED position.
3. While holding the “+/-” switch UP, turn the power ON.
Release the “+/-” switch when the console has powered
up.
4. The console will display “SPEC” (SPECIAL CAL and the
warning light will flash. See Illustration 12. Dashes will
appear in the lower right display until the rotary dial is
moved to one of the SPECIAL CAL positions (TARGET
RATE, ADJUST RATE, BOOM WIDTH, DISTANCE,
FLOWMETER, MIN FLOW, FIELD FLOW OR TOTAL
FLOW).
5. To exit SPECIAL CAL mode press the RESET switch. (Do
not exit until all desired settings have been adjusted).
