The Micro-Trak MT-3000 Automatic Sprayer Control system
has 5 major components:
1. Control Console
2. Flow Sensor
3. Speed Sensor
4. Servo Control Valve
5. Optional Electric Boom Solenoid Valve.
Capabilities
The MT-3000 is designed to operate with sprayers pumping
non-abrasive liquids. The operator may select any one of
seven (7) monitored functions. A mechanical pressure gauge
is provided for the operator to monitor system pressure.
NOTE: Do Not connect pressure gauge to liquid fertilizer.
Capacity
THE MT3000 IS AVAILABLE IN SEVERAL SIZES
1. FM 750 GFN flowmeter and 1” servo. - This system is
designed to have an excellent control range on sprayers
with high output pumps running in the 2 - 40 GPM
(7-150 lpm) range.
2. FM 750 GFN flowmeter and ¾” servo - This system is
designed to have good control range on sprayers with
marginally sized pumps running in the 2 - 40 GPM (7-150
lpm) range. Common on lawn care equipment.)
General Description 3. FM 500 flowmeter and ¾” inch servo - This system is
designed to have excellent control range on sprayers
with properly sized pumps running in the .5- GPM (2 - 38
lpm) range.
4. FM 750 SS stainless steel flowmeter and 1” high pressure
Servo - This system is designed to have excellent control
range on sprayers with high output pumps and high
pressure valve requirements up to 300 - PSI (20 bar), in
the 2 - 40 GPM (7 - 150 lpm) range.
5. FM 2000 flowmeter and 1” servo - This system is designed
to have good control range on sprayers with very high
output pumps running in the 19 - 198 GPM (72 - 750
lpm) range.
Controlling
In operation the control console computes the actual
application rate from the flow and speed sensor signals. It
then compares it to the target application rate and sends
an error signal to the servo valve. The servo then adjusts
the system’s flow to maintain a uniform application rate.
Spraying automatically starts and stops when forward ground
speed is sensed.
Installation
Proper installation and calibration is necessary in order for
the MT-3000 to work efficiently. If, after thoroughly reading
this manual, you have any questions on how to install,
calibrate or use this product, contact your local dealer or call
Micro-Trak at 800-328-9613.
Optional Equipment
THE BOOST VALVE KIT P/N 00118
Assures fast response to pressure surges caused by switching
individual boom sections on or off. When one or more booms
are off, liquid is bypassed through a valve which is adjusted
to maintain the flow that was passing out the boom.
THE CONVENIENCE KIT P/N 00119
Includes almost all of the components needed to make
installation easier plus three solenoid valves needed for
a three boom application for those sprayers not already
equipped with boom solenoids. The installation of boom
solenoids greatly simplifies operation by allowing the
console to turn the booms off when in HOLD.
THE REMOTE RUN/HOLD KIT P/N 10487
Automatically turns the solenoids of and stops acre
accumulation when equipment is raised, such as turning on
end rows. This eliminates the possibility of operator caused
errors and reduces the workload at a critical time.
THETRAKSTARULTRASONICSPEEDSENSORP/N00125
Replaces the standard magnetic wheel sensor to give true
ground speed readings regardless of slippage. This can
greatly reduce error caused by wheel slip and changes in
soil type.
GM INTERFACE MODULE P/N 00167
Allows any Micro-Trak Systems monitor or control system
to be connected to the electronic Speed-O-Meter system
on most 1988 and newer General Motors pick-ups. The GMI
plugs into the vehicle’s Assembly Line Diagnostic Link (ALDL)
connector.
THE NH3500 KIT P/N 00140
Allows you to accurately monitor and control the application
of anhydrous ammonia. The NH3500 kit has maximum
output capacity of 6000 lbs. (2722 kg) NH3 per hour, and
minimum output capacity of 600 lbs. (272 kg) NH3 per hour.

Before you begin your installation, take a few minutes
and confirm that you have the correct system for your
application. Use the following equation to calculate your
flow rate in GPM (lpm).
FLOW RATE = Spray Rate X Speed X Width feet (meters)/Constant
FLOW RATE - Flow rate in Gallons (liters) per minute.
SPRAY RATE - Application Rate in Gallons (liters) per Acre (hectare).
SPEED - Ground Speed in Miles (kilometers)) per Hour.
WIDTH - Total Boom width in feet of meters.
CONSTANT - 495 for English or 600 for Metric.
Go through the equation twice, first using your maximum
spray rate and maximum speed, and the using your minimum
spray rate and minimum speed. The FM 500 should not be
used for flow rates above 5 GPM (19 lpm) or below 0.5 GPM
(1.9 lpm). The FM 750 GFN should not be used for rates
above 40 GPM (150 lpm) or below 2 GPM (7 lpm). The FM
2000 should not be used for flow rates above 198 GPM (750
lpm) or below 19 GPM (72 lpm). NOTE: Accuracy may be
unpredictable outside the indicated range of each meter).
Operation with 2 booms shut off could results in lower
flowmeter limit being exceeded.

Installation (cont.)
General Installation
YOUR SPRAYER
All the components of your sprayer must be sized correctly
and in good working order. Plumbing Guideline on page 32
will give you some suggestions, but the details on proper
plumbing are basically beyond the scope of this manual.
Nozzle manufacturers offer detailed application literature
which includes valuable technical information. The MT-3000
will make a properly designed system perform far better than
any manually operated system. The MT-3000 can not make
a poorly plumbed system perform properly and may cause a
marginal system not to operate at all. You sprayer dealer and
chemical supplier want you to be successful and will assist in
selecting proper equipment.
SPRAYER PLUMBING
Remove all valves and regulators not shown in the system
diagram. See page 8. For ease of use and to maximize the
benefits of your MT-3000, you should replace manual boom
valves with electric solenoid type valves.
WELDING
Unplug the wiring harness from your MT-3000 console
before doing any welding on your equipment.
EXTENSION CABLES
Enough cable is provided for typical sprayer applications
such as pickups, high-boys, 3 point hitch, etc. If you need
more length 5’, 10’, 15’ and 20’ extensions are available.
TIPS ARE THE KEY
Many sprayers today are operating with wrong size, worn,
damages, clogged or improperly installed spraying tips.
Make sure your tips are correct and in good condition.
CAUTION: Never put chemicals in your sprayer until it has
been completely checked out with water to verify proper
operation.
9
Mounting the Display Console
Select a mounting location which seems most workable,
and 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.
NOTE: Route wiring harness away from sharp edges, heat,
moving parts or area of operator movement. Allow enough
slack at hitch connections for turning.
Make a ground wire using an 8” (20cm) length of 14 GA.
BLUE wire. Crimp a female tab terminal on one end and a
¼” ring terminal on the other end.
Mount console bracket and one end of ground wire on a
flat rigid surface using the ¼” bolts or self-tapping screws
provided. See Illustration 1.
Insert mounting knob through “U” bracket and rubber
washer. Rubber washer will hold knob in place while
installing the console. Insert console and secure with
adjusting knobs. Connect ground wire terminal on console.

12 VDC Electrical Installation
Your MT-3000 will work on either positive or negative
ground 12 volt systems. Route wires away from hot engine
components, moving parts and high tension (spark plugs)
wires. Cut wires to proper length, crimping on appropriate
terminals and secure with plastic ties to prevent rubbing or
pinching.
STEP 1
Connect the ORANGE/BLUE jacketed cable to battery
using 5/16” insulated ring terminals. Orange connects to
“HOT” terminal and BLUE to chassis ground terminal. See
Illustration 3.
STEP 2
Connect single ORANGE wire to “ON” terminal of ignition
switch. Use a 12 volt test light to locate terminal which is
“HOT” only when switch is on. (Other possible locations
are hour-meter, fuel, tem or volt gauge.) NOTE: Do not
connect to ignition coil as console damage can result. See
Illustration 4.
NOTE: On dual battery 12 volt systems, all power wires
must be to the same battery. Connect the ORANGE/BLUE
cable (step 1) and then temporarily disconnect the other
battery before testing and connecting the single ORANGE
wire (step 2).
STEP 3
Connect single BROWN wire to lighting circuit. Some
possible locations include light switch, fuse black, headlight
or dash panel light. (This wire is for gauge light only and is
not required for proper operation of console. See Illustration

Magnetic Speed Sensor Installation
The speed sensor has a YELLOW cable tie near the connector
and mates with the main harness cable also having a
YELLOW tie near the connector. Make sure you install the
correct sensor.
Prepare magnet clips as shown. You may also
glue magnets directly to hub using epoxy or
other quality adhesive. Be sure magnets are
evenly spaced at least 2” (5 cm) apart or speed will
not be steady and spray rate will be erratic. We
recommend 1 magnet be installed for each wheel
bolt. Tighten cable ties as shown on next page.
NOTE: If the magnets are closer than 2” (5 CM)
apart their fields may interact causing erratic
operation. Correct this situation by using an even
number of magnets and reversing the polarity
of consecutive magnets. Use a test magnet with one side
marked to check polarity of each installed magnet. On
magnet should attract and the next repel.

Trak-Star Ultrasonic Speed Sensor
GENERAL MOUNTING INFORMATION
1. Trak-Star must be mounted parallel to the ground.
The ultrasonic horn is preset for the proper angle of
reflection.
2. The unit must be located so that the signal has an
unobstructed path to the ground.
3. Trak-Star may be mounted with the horn anywhere
between 20 (.5 m) and 40 (1m) inches above the
ground.. In soil that is smooth, dry or sandy, it is better
to stay between 20 (.5 m) and 30 (.75 m) inches.
4. Mount the Trak-Star at the high end of the range
when working grassy areas or fields with heavy residue,
(Materials such as dried plant stalks can damage the
transducer.)
5. The Trak-Star must not be mounted in an area where it
could be subject to chemical spray.
6. The Trak-Star will work equally well with the sensor horn
pointing forward or backward. Generally it will be easier
to obtain a clear path to the ground by mounting it on
the front of the vehicle pointing rearwards. Remember
to avoid chemicals and plant stalks.
7. If the Trak-Star is mounted under a vehicle, echo
interference may occur. If the monitor is slow to register
speed, if speed drops toward 0 or if speed continues
after stopped, echo interference is present. Try a
different mounting location.
8. Mount the Trak-Star away from engine radiators,
other sources of heat and direct sunlight. Extreme
temperature will affect measurement accuracy.
EXAMPLES OF BAD INSTALLATION
Possible Signal Interference

The foam pad on the front of the Trak-Star is a filter that
should be kept in place during operation. It is intended
to keep bugs, sand, etc. from damaging the transducer
membrane.
If Trak-Star begins to give erratic reading, the foam may
be need cleaning. Remove the pad and thoroughly clean
in warm soapy water. Rinse, and remove excess water
using compressed air.. Reinstall the foam and check sensor
operations.
The Trak-Star may not function properly is excessive moisture
is present on the foam. (Beads of water from heavy dew,
rain, etc.). Simply wipe dry and check operations.
Trak-Star can be used without the foam pad, however,
extreme care must be exercised, especially in windy
conditions or in fields with vegetation tall enough to contact
the Trak-Star.
Operation of the Trak-Star without the foam may allow
debris to damage the transducer membrane, thus requiring
a non-warranty repair which costs the customer both time
and money.

2. IMPORTANT: For proper operation the sensor must
be properly aligned to the direction of travel and
parallel to the ground. Carefully mark the location of
the mounting bolts on the frame (or bracket) and drill
holes. Temporarily attach the unit with hex nuts to
check position.
NOTE: When leveling unit be sure tractor or implement is

4. Remove backing from decals provided and place
over unused mounting channels to prevent dirt
accumulation.
5. Run the adapter cable to the control console’s speed
sensor cable, avoiding other electrical wiring and areas
of high heat or abrasion. Secure cable along entire
length with cable ties. DO NOT plug cables together
until calibration is complete.
NOTE: See calibration information on the next page for
additional calibration information.
Adapter Cables
By substituting the appropriate cable for the MT-3000/5000
cable supplied, the Trak-Star ultrasonic speed sensor may
also be used with a variety of other makes and models of
controllers and monitors including: Micro-Trak, Calc-An-
Acre, Flow-Trak, Yield-Trak, Dickey-john, Gandy DAS, Hiniker,
Magnavox, Raven and SED/Field Electronics.
GENERAL INFORMATION
1. All adapter cables are equipped with a six pin connector
for direct connection to the Trak-Star and an appropriate
mating connector on the other end to plug into the
monitor/controllers standard speed input cable.
2. The adapter cables for units which do not provide a
power source for the speed sensor have an attached tow
conductor power card which must be connected to the
tractor or vehicles’s 12 VDC power system.

Care and Maintenance
1. Always cover or remove the Trak-Star before traveling at
highway speeds. Flying rocks, road sand and bugs can
damage the transmitter/receiver. Physical damage IS
NOT covered by the factory warranty.
2. Trak-Star’s case is watertight under normal weather
conditions and washing. However, do not subject the
unit to steam or pressure cleaning.
3. Keep the transmitter horn free of dirt and mud. The horn
should be cleaned with low pressure water or an aerosol
automotive brake cleaner or electronic contact cleaner.
DO NOT use base ph liquids on horn. DO NOT insert
screwdrivers or other sharp objects into the horn.
4. When cable are disconnected, plug in the protective end
capsto prevent dirt or waterfrom entering the connectors
which may result in corrosion or poor contact.
5. Nicks or cuts in cable insulation should be immediately
sealed or repaired to prevent corrosion to the wire or
short circuits.
6. If an arc welder or any other source of high voltage will
be used on the tractor or implement, disconnect all
ground and power to prevent damage to the electronic.

If under actual field conditions you find that your speed
measurements (or distance) is consistently off, as determined
by another independent measurement, you can fine-tune
the system by following the speed calibration instructions
for your particular monitor/controller and increasing or
decreasing the speed calibration value by a small amount
and then rechecking the accuracy. Repeat as necessary until
true readings are achieved.
NOTE: With some systems, the speed calibration value
can not be adjusted with the console. In these cases,
adjustments to the speed measurement can be made by
slightly raising or lowering the horn end of the Trak-Star.
For each degree of angle that the horn is raised, the console
display will show an increase in speed of 1.3%. Likewise for
each degree that the horn is lowered, the speed will show
a decrease of 1.3%.

Troubleshooting
NO SPEED
Trak-Star should emit a “crackling sound”. If not, check for
12 volts between pins A and B of the adapter cable six-pin
connector. If 12 volts is present but Trak-Star does nor
crackle, Trak-Star is defective. If there is no power from A and
B, check cable and connections.
Use a jumper wire (paper clip bent in a “U” works well)
and several times rapidly short together pins E and F of
the adapter cable. If console responds with some SPEED
reading, console and adapter cable are OK and the problem
may be in Trak-Star. If console will not respond, problem
may be in console or adapter cable.
SPEED ERRATIC, INTERMITTENT, SLOW TO RESPOND
OR NO SPEED AT ALL
This can be a result of echo interference when mounted
under vehicle. Move Trak-Star all the way to front and
pointed forward or all the way to rear and pointed rearward.
Remember to avoid chemicals and plant stalks.
Some ground surfaces (hard packed dirt or gravel; soft,
smooth sandy or powdery soil; some asphalt and concrete;
etc) may cause weak signals. If you experience erratic
operation under any of these conditions, try a lower mount
height.
Dirty Foam - Dust can usually be removed by tapping on the
foam. For anything other than dust, the foam will have to be
thoroughly washed.
Remove the foam and thoroughly clean it with soapy
water. (The foam can be removed without unscrewing the
retaining bracket. Completely rinse the soap and squeeze
out the water. Re-install the foam and check sensor
operation. The Trak-Star may also not function properly if
excessive moisture is present on the foam.
In some extreme conditions where marginal signal is
present, the foam may cause erratic operation. The Trak-
Star can be used without the foam. However, extreme care
must be exercised, especially in windy conditions, or in
fields with vegetation tall enough to contact the Trak-Star.
It would be better to leave the foam in place and relocate
the Trak-Star to a more suitable location.
Dirty transducer or holes in transducer membrane. Gently
flush horn with water and pat dry with soft cloth. (Do not
use high pressure or compressed air.) For oil or chemical
contamination, you may use an automotive aerosol brake
cleaner or aerosol electronic contact cleaner. If crackling
quits and will not come back within a minute or two, the
transducer membrane has been damaged and must be
replaces. NOTE: Do not use base ph liquids on transducer.
When driving over standing water or smooth wet surfaces,
the signal from the sensor may be deflected, resulting in a
temporary loss of speed measurement. Speed readings will
resume once the wet area has been passed.
Poor Ground - Run the Trak-Star’s blue ground wire direct to
the battery or the battery cable at the engine block.
SPEED READING WHILE STOPPED
Occasional reading of up to .5 MPH (1.2 kph) while stopped
may occur, especially when in or around buildings or other
machinery.
Echo interference from inadequate installation may cause
speed reading while stopped. Relocate the Trak-Star if this
occurs.
SPEED STEADY BUT INCORRECT
If the six-pin connector is mated with power applied, the
Trak-Star may program for the wrong monitor. Cycle power
after the six-pin connector is mated.
The six-pin connector of the Trak-Star is labeled A-F. Positions
C and D program the Trak-Star for the appropriate monitor.
If the wires to C or D are broken, pulled out or shorted, the
Trak-Star may be incorrectly programmed.
On monitors with adjustable speed calibration, fine-tune
calibration as needed to get correct speed. On monitors
without adjustable calibration, fine-tune speed by making
small changes in Trak-Star mounting angle.

Installation (cont.)
Plumbing - General
Refer to system diagram on page 6 for component
locations.
NOTE: Before beginning plumbing, make sure you have
the correct system. See Pre-installation section on page
9. Once installed, the servo or flowmeter can not be
exchanged for a different size.
FORBEST PERFORMANCE AND UNIFORMITYOFSPRAY
1. Minimize use of elbows, tees, nipples, reducers or
anything else that restricts flow.
2. Use pump with enough capacity to handle flow to
nozzles, agitation line and servo valves.
3. Use pressure relief valve set at 60-80 PSI (4 - 5.5 bar)
on positive displacement pumps or centrifugal pumps
capable of more than 6.5 PSI (4.5 bar).
4. Pump output line should be 1” minimum.

1. Flowmeter must be installed at the pump output after
any strainers, return lines or valves. Securely mount
flowmeter (hardware not supplied) in an area away from
intense vibration in a vertical position. The flowmeter
may need periodic cleaning, there fore, it should be
easy to remove. Liquid can flow in either direction but
up is preferred. Make connections using ¾” fittings
without the use of reducers, elbows or sharp bends for a
minimum of 6” (15 cm) either side of the meter.
2. Apply a small amount of grease to the sensor threads and
screw sensor all the way onto hole of flowmeter. The flow
sensor has a GREEN cable tie near the connector which
mates with main harness cable also having a GREEN tie
near the connector. Tighten 3/8” jam nut to lock sensor
in place. Secure cable with plastic ties.
NOTE: Save plastic plugs to protect flowmeter during
storage.

Pressure Relief Valve
If you have a positive displacement pump or a centrifugal
pump capable of more than 65 PSI (4.5 bar) you must install
a pressure relief valve and adjust it to a safe maximum
pressure. NOTE: See Plumbing Guidelines on page 32 for
adjustment procedure. If a positive displacement pump is
operated without a pressure relief valve, damage may result
to pump or other plumbing component.

5. For pumps rated above 50 GPM (190 lpm), use 1½”
suction line and 1¼” servo valve return line. Plumb
return line into pump inlet or back to tank (not
agitation). Line must have unrestricted flow.
6. Boom having flow greater than 5 GPM (19 lpm) should
use ¾” lines minimum.
NOTE: See Plumbing Guidelines on page 32 for additional
information.

Installation (cont.)
Range Adjust Valve
With over-sized pumps it may be necessary to install a range
adjust valve. The range adjust valve will make your pump
appear smaller to the rest of the system. Adjustment of this
valve is covered in the Pre-Field checkout on page 21.

Servo, Throttling & Boost Valves
Although installing boost valve does involve additional
expense, it offers instant flow response and assures sufficient
by-pass by automatically opening when a boom is shut off.
1. When Servo and throttling valves are installed without
boost solenoid the outlet of the servo valve must be
connected directly to the pump inlet or into the tank
with no restrictions. Connection to the agitation line will
probably cause slow response and marginal operation.
Connect the 5’ (1.5 m) servo cable (reverse connector
and orange boost valve wire) to the servo.
NOTE: If boost valve is not used, tape off orange with to
prevent shorting to frame. (If this wire shorts to frame
ground, the internal circuit breaker will trip, turning booms
off and stopping acre count.)
NOTE: The servo may connect directly to the servo lead on
the main harness (reversed connector). If more length is
needed use the 5” (1.5 m) servo cable.
2. Use this plumbing diagram if your boost valve has flo-
thru port. Crimp 1 female tab terminal onto ORANGE
wire of servo valve cable (reversed connector.) Slip it
on boost solenoid terminal. Cut a length of 14 Ga. BLUE
hook-up wire and crimp a female tab terminal on one
end and a ¼” ring terminal on the other. Ground other
solenoid terminal using this wire.

WARNING: Do not use the MT-3000 pressure gauge for
toxic chemicals or materials in compatible with nylon,
EPDM, brass, tin/lead solder or phosphor bronze (such as
liquid fertilizer). Use a suitable gauge mounted in a safe
location or install a gauge protection (diaphragm).
Three fittings are provided for the pressure line: a female
elbow, a male connector and a union for quick connection
at the hitch. The fittings have pre-installed “O” rings which
should be replaced with the 4 EPDM “O” rings supplied. Also
supplied is a small snubber washer to be installed in the
male connector. (The snubber washer allows pressure, not
volume, to get to the pressure gauge. Should the tube break
it will seep slowly rather than spray vigorously.
3. If your boost valve does not have flo-thru port, you must
add a “T” fitting.
NOTE: To assure a good connection and avoid corrosion,
coat servo and solenoid lugs with silicone grease.
Ground “Jumper” Installation
If you are spraying with a drawn implement, you must
attach a ground wire “jumper” to complete the electrical
circuit across the hitch for the solenoid valves. One end is
connected to sprayer hitch, the other to your tractor frame.
Cut 2 appropriate lengths of 14 Ga. BLUE wire.. Crimp a ¼”
ring terminal to one of each. Crimp a male tab terminal on
the other end of one wire and a female tab terminal to the
other wire,
Using ¼” bolts, attach one wire to implement frame and the
other to the tractor. Plug the male and female tab terminals
together. Always apply silicone grease to exposed or partially
exposed electrical connections to prevent corrosion.

NOTE: If you are using electric boom solenoids, you may
have to install a light bulb or some other 12 volt load in
place of the solenoids to get the monitor to acknowledge
boom widths and count area.
Optional Remote Run/Hold Installation
The remote Run/hold (shortest cable on the main harness)
option automatically turns the solenoid valves off and stops
the acre accumulation when equipment is raised, such
as turning on end rows. The remote sensor overrides the
console when the master switch is in the AUTO or MANUAL
position. (The remote sensor is the same as the magnetic
speed sensor and has a YELLOW cable tie near the connector.
The basic idea is to attach a magnet to a lever or some part
of the equipment that moves when the implement is raised
and lowered. When the magnet is away from the sensor the
console will be in HOLD and will shut off the solenoid valves
and stop counting acres.
NOTE: The Run/’Hold sensor is 3 feet (1 m) long. You may
require extension cables which are available in 5 ft. (1.5 m),
10 ft. (3 m), 15 ft. 4.5 M) and 20 ft. (6 m) lengths.
You may also use a toggle or other type switch. Simply
cut the BLUE jumper wire in the dust cover and splice on
a appropriate length of wire to reach your switch. When
switch is closed, console is in RUN (provided master switch
is in AUTO or MANUAL). When switch is open, console is in
HOLD.

Calibration
Console Calibration
Calibration is simply a procedure that adapts the MT-3000
console to your particular equipment. There are two types
of calibration: DIRECT and AUTO. Direct calibration lets you
enter calibration numbers into the console using the “+/-”
switch. Auto calibration will automatically set the calibration
number while you watch the effect on the corresponding
total. (This feature will be explained in further detail later in
the calibration section of this manual.
IMPORTANT: The MT-3000 WILL NOT work properly if any
of the calibration values are incorrect.
ENTERING DIRECT CALIBRATION MODE
STOP your vehicle, place pray selector in HOLD, and turn
switch to CAL. After a three (3) second pause, the display
will read out width of center boom and a red warning light
(located above and left of the pressure gauge) will come on.
The console in now in the calibration mode and the rotary
switch will select the inner green ring of calibration settings.
The console will stay in the calibration mode as long as the
vehicle remains stopped and the console stays in hold. A
power interrupt will cause the console to lose the calibration
mode. The red warning light is always on during console
calibration.
NOTE: If you have a Trak-Star Ultrasonic Speed Sensor or
radar you should disconnect it from the MT-3000 console
when calibrating. While standing still the Trak-Star or
Radar may emit an occasional pulse which will take the
MT-3000 out of calibration.
ENTERING BOOM WIDTHS
The three (3) bottom positions are for entering the effective
spray width of the left, center and right booms. Turn the
selector knob to the following positions to enter the boom
widths: Left Center Right
BOOM WIDTHS MUST BE IN INCHES/METERS TO WORK
PROPERLY. Unused booms should be programmed to zero.
NOTE: Consult your chemical supplier if you have questions
regarding broadcast versus banding application rates.

MINIMUM FLOW RATE: The MT-3000 will not allow the
flow rate to drop below this limit in automatic
control. It has been factory preset to 2.00 GPM
(7.5 lpm), the minimum recommended flow
rate for the FM750 GFN flowmeter when used
with the MT-3400. You may want to change this
value to the minimum recommended gallon per minute of
your nozzles. The purpose of this feature is to keep pressure
from going too low and causing a poor spray pattern.
EXAMPLE: If you have 15 nozzles that put out .22 GPM (.83
lpm) at their minimum recommended pressure, enter 3.30
(12.5) into console 15 X .22 GPM (.83 lpm) to assure good
spray pattern.
CAUTION: If the minimum flow rate is greater than the
actual flow rate, over-application in automatic may occur.
The the Pre-installation for calculation of the actual flow
rate.
TARGET SPRAY RATE: Enter desired application rate in
LITERS PER HECTARE or GALLONS PER ACRE.
When in AUTO, the console will lock onto
this value and automatically open or close
the electric servo valve to maintain uniformed
application.
DELTA ADJUST RATE: Enter value to be used for on-the-
go adjustments to Target Rate. If this feature will not be
used, enter “0” to avoid accidental changing of Target Rate.
EXAMPLE: Target Spray Rate is set to 10.00 and
Delta to 1.00. Each time “=/-” toggle is flipped,
Target will increase or decrease by 1.00. (Works
only with Master Switch in AUTO and rotary
Selector Knob at SPRAY RATE or % ERROR.
FLOWMETER CALIBRATION: Enter factory calibration
value stamped on metal tag attached to the
flowmeter. If you are spraying materials with
a specific gravity or viscosity different than
water, meter calibration should be checked
for that material. See AUTO CALIBRATION - Flowmeter on
page 25. This calibration value will not go below 10.0 (.01) or
above 1920.0 (6553.5).
DISTANCE/SPEEDCALIBRATION:Thisvalueisequaltothe
distance traveled (meters/inches) between
