Introduction
MT-3405 FTW
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.
Insert 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.
Illustration 1
Tools Needed to Install MT-3405 FTW
• Screwdrivers • Pliers
• Set of Wrenches • Wire Cutter
• Electric Drill and Bits • Hammer
• 12-Volt Test Light • Hacksaw
• Center Punch • Bench Vise
The MT-3405 FTW is a flow-based control system which is
designed to be used on sprayers with diverting (three-way)
boom valves.
Using typical boom valves and a Micro-Trak flow-based rate
control system, when one of more of the boom sections are
turned off, the flow of liquid is discontinued to that boom
section, and flow is adjusted through the remaining boom
sections so that application rate (when in automatic) is not
affected.
Using the diverting (three-way) valve and the MT-3405 FTW
flow-based control system, liquid is actually diverted or
by-passed back to the tank. With the special “FTW” software,
the MT-3405 FTW counts only the liquid that has been
sprayed.
The MT-3405 FTW system uses individually entered boom
widths to determine which portion of the total liquid is being
by-passed rather than sprayed from the boom section. For
this reason, it is extremely important to adjust and verify
the amount of liquid that is diverted by the three-way valve
when a boom is shut off. Please read your sprayer’s operating
manual for details, or see Appendix C for basic instructions.

Electrical Installation
The MT-3405 FTW must be connected to a 12-volt DC elec-
trical system. Power is connected directly to the battery. The
MT-3405 FTW 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 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 off 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 on the white wire, as illustrated,
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 contact.
Your MT-3405 FTW is equipped with an advanced electronic
memory which does not require a constant supply of pow-
er 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.

PLEASE NOTE: If you have purchased a Trak-Star speed
sensor, disregard the section on magnetic speed sensors
and install the Trak-Star as described in the instructions
packed with the unit.
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.
Installation (cont)
Speed Sensor Installation
Locate the Following Parts:
• Speed Sensor Cable
• Mounting “L” Bracket
• Magnet Clips
• Magnets
• Cable Ties
Magnets
Please read the following information about magnet spacing
and polarity.
The number of magnets that must be used depends on
where you mount the sensor. The general rule for tractor
or implement wheels is one magnet for each wheel bolt
(minimum of two, and always use an even number). For drive
shafts or small wheels (ATV’s), a minimum of two magnets
are required.
The magnets provided by Micro-Trak are marked with
a 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.

Attaching Magnets
Refer to the following diagram for general mounting
instructions. For specific mounting instructions, refer to
Appendix A in the back of this manual.
NOTE: Magnets may be attached mechanically as shown or
adhered with epoxy or other high quality adhesive. When
using adhesive, thoroughly clean the area of dirt and oil.
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-3405 FTW 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.

Connecting the Speed Sensor Cable
The speed sensor cable has a GREEN sensor body and mates
with the main harness cable having a YELLOW cable tie near
the 3-pin M/P connector. Make certain that you install the
correct sensor cable and connect it to the correct connector
on the main harness. 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 main
harness lead with the YELLOW tie and flow sensor always
connects to the main harness lead with the GREEN tie.
See Illustration 5.
INSTALLATION NOTE: The main harness provides two
connection points for the speed sensor. For speed sensor
installations in the cab or near the control console, it
may be more practical to use the local access connector
(YELLOW tie) on the control console pigtail exiting the rear
of the console. Using this connection point will disable
the connection point on the end of the main harness. For
speed sensor installations on implements, it may be more
practical to use the speed connector on the end of the
main harness. When using this connection point, make
certain that the local access connector for speed/distance
is mated together.
The Run/hold sensor, which plugs into the other main
harness cable, also uses the same type of connector as the
speed and flow sensors. However, the Run/hold sensor has a
GRAY tie near the 3-pin connector, the sensor body is BLACK,
and it always connects to the main harness lead with the
GRAY tie.

The Flowmeter must be installed in the boom supply line
after any strainers, return lines, or valves, but before the
boom shut-off valves. Securely mount flowmeter (hardware
not supplied) in a vertical position in an area away from
intense vibration. DO NOT install flowmeter closer than 12”
to the servo valve or the boom shut-off valves. (The flow-
meter may need periodic cleaning, so it should be easy to
remove). The flow meter is a bidirectional meter (exception:
Polmac’s 1 1/2” - 3”). Liquid can flow in either direction, but
up is preferred. Make connections using 3/4” fittings without
the use of reducers, elbows or sharp bends for a minimum of
six inches (15 cm) either side of meter. See Illustration 6.

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 9. 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 Braglia

or other 12-volt control valve, please refer to 12-Volt Control
Valve Calibration on page 39.
NOTE: The servo valve may be installed in the main spray
line. For in-line installations, you will need to cut the servo
cable and reverse the wires. Connect the RED wire to the
BLACK wire and vice versa. Failure to reverse the wires will
result in the servo valve operating backwards.

The relief valve is used to “dump” pressure when all boom
valves are turned off. Whenever all the boom control
switches are turned off, or when HOLD is selected with the
master switch, the relief valve should be open. Use this
plumbing illustration (See Illustration 10) as your pattern
for proper installation if your relief valve has a flow-through
port. DO NOT install the relief valve closer than 12” to the
flowmeter. Locate a 2-pin solenoid cable and connect it to
the relief valve using an appropriate method. Connect a
2-pin M/P connector to the module cable with no colored tie.
Be careful not to connect the relief valve cable to one of the
boom shut-off leads. All of the boom shut-off leads have a
colored tie near the 3-pin M/P connector. the relief solenoid
lead does not.
If all valves are NOT the same type (all solenoid or all ball
valves), refer to Appendix B for wiring instructions.
If your relief valve does not have flow-through port, you must
add a “T” fitting. See Illustration 11.
NOTE: To assure a good connection and avoid corrosion,
coat electrical connections with silicone grease.

Boom Shut-off Valves
Locate the boom shut-off cables. Crimp the insulated female
spade terminals provided with the cables to both wires. (If
valves have wires, crimp terminals on those wires). Attach
the cables to the terminals on the boom valves. Normally,
wires connect red to red and black to black. If valves operate
backwards, reverse connections. Apply silicone grease to the
terminal connections to help prevent corrosion and insure a
good electrical connection.
Locate the colored cable ties included with the boom shut-off
cables. Attach a BROWN tie near the 2-pin M/P connector on
the boom one (1) cable. Attach a RED tie near the 2-pin M/P
connector on the boom two (2) cable. Attach an ORANGE tie
near the 2-pin M/P connector on the boom three (3) cable.
Attach a YELLOW tie near the 2-pin M/P connector on the
boom four (4) cable. Attach a GREEN tie near the 2-pin M/P
connector on the boom five (5) cable.
Connect the 2-pin M/P connectors to the mating connectors
on the main harness. Boom one (1) connects to the mating
connector with the BROWN cable tie near the connector.
Boom two (2) connects to the mating connector with the
RED cable tie near the connector. Boom three (3) connects
to the mating connector with the ORANGE cable tie near the

Lift Wheel Mounting
Hydraulic Cylinder Mounting
Remote Run sensor on hydraulic cylinder. Magnet and sensor
are in line when equipment is lowered and operating.
The run/hold sensor cable has a black body and a GRAY tie
near the 3-pin M/P connector and mates with the main har-
ness cable having a GRAY cable tie near the 3-pin M/P con-
nector. Make certain that you install the correct sensor cable
and connect it to the correct connector on the main harness.
The run/hold sensor has a BLACK body. DO NOT use a speed/
flow sensor (GREEN body). See Illustration 13.
• Attach a magnet to a lever or some part of the equipment
that moves when the implement is raised and lowered.
The Hall-effect run/hold sensor is sensitive only to the
south pole (side with dashed line) of the magnet. Check
the polarity of the magnet by bringing it near the run/
hold sensor with the console turned on. Note and mark
the face of the magnet that is toward the sensor when
the console does not indicate “HOLD.” When the magnet
is away from the sensor, the console will be in HOLD and
will shut off the boom valves and stop counting acres.
NOTE: The run/hold kit includes a 5’ sensor cable
and 10’ extension. You may require additional
extension cables which are available in 5 ft. (1.5
m), 10 ft. (3 m), 15 ft. (4.5 m), 20 ft. (6 m) and 25 ft.
(7.6 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
an appropriate length of wire to reach your switch.
When switch is closed, console is in RUN. When the switch is
open, the console is in HOLD.
INSTALLATION NOTE: The main harness provides two
connection points for the run/hold. For Run/Hold installa-
tions in the cab or near the control console, it may be more
practical to use the local access connector on the control
console pigtail (GRAY tie) exiting the rear of the console.
Using this connection point will disable the connection
point on the end of the main harness. For run/hold sensor
installations on implements, it may be more practical
to use the run/hold connector on the end of the main
harness. When using this connection point, make certain
that the local access connector is mated together.

To enter or change any of the system’s calibration values,
you must enter calibration mode. To enter calibration mode,
STOP the vehicle, place the run/hold switch on the front
panel in HOLD and press and hold the CAL button until “CAL”
lights up (approximately three seconds). (NOTE: Calibration
may be entered while moving, but it is not recommend-
ed to attempt calibration while the vehicle is moving).
The console will remain in calibration mode, with the RED
warning light illuminated until you exit calibration or turn
power OFF.
Once in calibration mode, you may change any one, all or
none of the values, in any order.* To select a calibration
position, simply turn the rotary selector to the desired
position. Calibration positions are identified with white
lettering inside boxes that are outlined in GREEN, on each
side of the rotary selector. All values are entered and
adjusted using the “+” and “-” buttons on the front panel.
*Test speed must be last.
TARGET RATE: Enter the value for the
desired target application rate in gallons per
acre (liters per hectare). This is the applica-
tion rate that the control console will lock
onto when operating in
AUTO.
ADJUST RATE: Enter the value for the desired amount
of change in gallons per acre (liters per
hectare) to be used for making on-the-go
rate adjustments when
operating in AUTO. For
example, if a value “1.0” is
entered, you will be able
to increase and decrease your application rate in one-gallon
(liter) increments during operation in AUTO. To disable this
feature, simply enter “.0” for a value.
TEST SPEED: Enter the value to be used for simulating
speed for performing Pre-Field System Checkout. The
console will use this
speed for simulating
spraying operations. The
test speed value is only
used while in calibration mode. Once CAL is
exited, the Test Speed value is reset to zero.
DO NOT ENTER A TEST SPEED UNTIL ALL OTHER VALUES
ARE PROPERLY ADJUSTED. Please refer to Pre-Field System
Checkout for details.
BOOM SEL: This position is used to select the boom
section to be calibrated. With the rotary switch in this posi-
tion, the display will show
the active boom section
number. Use the “+” and
“-” buttons to select the
boom section to be calibrated. Once the
desired boom section has been selected, turn
the rotary selector to width to enter the effec-
tive working width for that boom section.
Repeat this procedure for each boom section.
Setting Individual Boom Width
In order to accurately measure the number of gallons (liters)
applied per acre (hectare) it is important to determine the
correct “working” width. The “working” width is the width
of ground being affected by any operation. This should be
measured to the nearest inch (thousandth of a meter).
Your “working” width will vary depending on the type of
equipment you are using and the method of application.
For example, if you are broadcast applying chemicals your
“working” width will be the number of nozzles times the
nozzle spacing in inches (mm). For example, if you have 20
nozzles spaced at 20 inches, the working width is 400 inches.
See Illustration 16.
Working Width
WIDTH: Enter the effective working width, in inches (milli-
meters) for the boom sec-
tion currently shown on
the display. Repeat this
procedure for each boom
section. Enter a value of “0” (.000) for any
unused boom sections.

CIRC: This position is used to calibrate the speed sensor
for accurate speed and distance measurement. When this
position is selected, the display will alternately show, every
three seconds, the wheel
circumference value and
the distance value. The
wheelcircumferencevalue
is the number shown along with “CAL” on the
display. See Illustration 17B. The distance
value is the number shown when “CAL” is not shown on the
display. Either one may be selected to calibrate for speed
and distance measurement. Select by pressing the “+” or “-”
button when the desired value is being displayed.
Working Width
Banding Application Calibration
In banding applications, you will still need to enter the total
width of each boom section so that area counts correctly, but
you must also calculate the percentage of your total width
the band is covering and reduce your target rate to match.
For example, if you are planting with an eight-row planter
with 30-inch spacing, your total working width, regardless
of the width of bands, is 240 inches (8 x 30 inches). Now, for
purposes of this example, you have eight 12” bands. Your
total band coverage is 96 inches (8 x 12 inches). Based on
that, your band is covering 40 percent of your total width
(96 divided by 240). If you want to apply 20 GPA in the
band, enter 8 GPA as your target rate (40 percent of 20 GPA).
See Illustration 17A.
To determine circumference, measure the
distance of one complete wheel revolution
and divide by the number of magnets installed .
Determining Wheel Circumference
For the console to calculate the correct number of acres
(hectares), both the circumference of the sensor-equipped
wheel and the implement width must be entered. Determine
the circumference of the sensor-mounted wheel to the
nearest tenth of an inch (thousandth of a meter) with the
following method:
METHOD
Mark tire with a piece of chalk and measure distance traveled
on the ground for one complete revolution. See Illustration 19.
For accuracy, measure the wheel revolution several times and
take the average. Divide that value by the number of magnets
installed on the wheel hub to get your starting wheel circum-
ference (CIRC) calibration value.

MIN FLOW: The purpose of this calibration parameter is to
prevent the system from applying below the recommended
minimum rate for the nozzles. Enter the minimum flow rate
in gallons per minute (liters per minute) based
on the nozzles being used, for the entire boom
on the sprayer. DO NOT
enter the actual flow rate
of your spray application.
For example, if the mini-
mum flow rate for the nozzle you are using is .22 GPM at their
minimum recommended pressure and your boom has 20
nozzles, enter 4.4 as the MIN FLOW value (.22 x 20 = 4.4). The
system WILL NOT apply at a rate lower than this value when
spraying in AUTO. This value should be checked/changed for
each different nozzle that you use.
APPLICATION NOTE: In certain situations, your ground
speed may be slow enough to result in over application. In
other words, based on ground speed, the actual flow rate
has dropped to the calibrated minimum flow rate.
20
Drive Shaft Speed Sensor Calibration
NOTE: If you have mounted the magnetic speed sensor on
a wheel, skip this step and go on to Fine Tuning Speed/
Distance Calibration Values.
Because of the difference in wheel-to-drive shaft ratios, it is
difficult to determine a calibration value for installation on
a drive shaft by measuring a wheel. You must start with an
estimated calibration value and then fine-tune the calibra-
tion.
1. Place the console in HOLD.
2. Press and hold the “CAL” key for three seconds to
enter the calibration mode. Turn the dial to “CIRC”
position. The display will alternate between the wheel
circumference (CIRC) and distance values at about three-
second intervals. (When the word “CAL” appears, the
number displayed is the wheel circumference (CIRC)
value. When “CAL” does not appear, this is the distance
value.)
3. When the display shows wheel circumference (“CAL” is
displayed) , use the “+” or “-” key to adjust the displayed
value to any number between 10 and 15 (255mm to
380mm). When the number shown on the display
matches the desired value, you have arrived at the
estimated calibration value. Exit “CAL” by pressing and
holding the “CAL” key for three seconds.
NOTE: If you let go of the “+” and “-” keys while you are
adjusting the CIRC value, the console will wait to make
sure you are finished. After 64 seconds, the display will
start alternating between the wheel circumference (CIRC)
and distance values again. Make sure you know which
value you are adjusting.
NOTE: For fine-tuning the wheel circumference (CIRC) value,
turn to page 26.
