Inline
The flow is controlled by the servo valve
located “inline” between pump and
flowmeter. This is the most common
configuration.
Bypass
The flow is regulated by the servo
valve located in a bypass line between
pump and the tank return line. This
configuration accomodates very low
application rates.

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,
lock-washers 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
Electrical Installation
The MT-3405F™ II must be connected to a 12-volt DC electrical system with the
included Terminal Kit (P/N 13270). Power is connected to the battery through a 30A
fuse. The MT-3405F™ II has an ON/OFF switch on the console to turn the power off
when the system is not being used.
Your MT-3405F™ II is equipped with a non-volatile 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.
Installing the Terminal Kit (P/N 13270)
1. Crimp 1/4” ring terminal to one of the orange wires and connect to positive
battery terminal (+).
2. Crimp yellow wire splice (provided) to other orange wire.
NOTE: This splice connector is filled with silicone grease to provide
moisture-resistance. Do not remove grease. Also, this connector should
be crimped on both the wire and the insulation. See Illustration 2 Below.
3. Locate white power wire on console. Strip insulation approximately 3/8”
back. Crimp moisture-resistant wire splice onto white power wire. Make sure
console’s power wire is properly routed and cut to length before assembly.
4. Insert 30A fuse (provided) in Fuse Holder. Close Fuse Holder cover.

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.
For proper operation, the
magnets must be evenly
spaced around the wheel or
drive shaft. The magnets must
be at least 1” apart.
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 - must be an even number.
Installation Note: The console provides one connection point
for the speed sensor. A 15 ft. extension cable is provided.
For speed sensor installations on implements, add 3-pin
extension cables as required.
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, see Appendix H.
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.

Test magnet
should alternately
attract and repel.
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.
The magnets provided
by Micro-Trak are marked
with a punched dashed
line on the SOUTH pole
side of the magnet.

12
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-3405F™ II 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
requirements shown in Illustration 3.
NOTE: Observe magnet polarities (see previous section).

Connecting the Speed Sensor Cable
The speed sensor cable has a GREEN sensor body and
mates with the 3-pin connector which is marked with a
yellow cable tie. 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 3-pin
M/P connector with the YELLOW tie and flow sensor always
connects to the 3-pin M/P connector with the GREEN tie.
See MT-3405F II Wiring Diagram on page 9.

Run/Hold Black Gray
The optional Run/hold sensor, 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. See MT-3405F II Wiring
Diagram on page 9.
Contact a Micro-Trak sales representative for details on any of these products,
or call Micro-Trak Systems, Inc. at 1-800-328-9613.
Speed Sensor Options
NOTE: In addition to the standard Hall-effect magnetic
speed sensor, the MT-3405F II may be interfaced with
a variety of other speed sensing equipment. Several
options are listed below.
ASTRO SERIES OR OTHER GPS SPEED SENSOR
INTERFACES
The MT-3405F™ II 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.
VANSCOTM 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-3405F™ II may also be interfaced with most radar
ground speed sensors. An adapter cable is required for
proper interface.

Installation (cont.)
Remote Run/Hold
To use the remote Run/Hold feature, the connector with the gray wire tie at the end of the Flow/Servo harness. If using a
switch, connect the switch (not supplied) across the 2 pins on the connector, or to the 2 wires behind the connector. Switch
OPEN = Run, Switch CLOSED = Hold.
This could be done nearer the console by connecting one switch terminal to ground, and the other switch terminal to the gray
wire on the 10-pin connector on the back of the console.
If using the Micro-Trak Hall-Effect Run/Hold Sensor Kit, connect the sensor cable to the connector with the gray tie. When
installing the sensor kit, mount so that when the sensor is near the magnet the system is in HOLD and when the sensor is away
from the magnet the system is in RUN.

The flowmeter must be installed in the main line after any
strainers, return lines, or valves. Securely mount flowmeter
in an area away from intense vibration. A vertical installation
with flow entering the bottom is preferred, especially at rates
below 5 gallons per minute. Other orientations are sufficient
providing the flowmeter remains full of fluid. To avoid erratic
flow readings allow a minimum of 6” of straight tubing at the
flowmeter input and output. If installation constraints don’t
allow this keep bends as gentle as possible. See Illustration 4.
Micro-Trak® flow meters are bidirectional (exception: green
plastic turbine and mag. flowmeters are one direction only).
Flipping the flowmeter periodically (black nylon and stainless
steel Micro-Trak manufactured models) to reverse the flow
will greatly extend the life of the flowmeter by evening out
bearing wear.
Installing Flow Sensor Cable
With the flowmeter in place, install the flow sensor cable.
The flow sensor cable has a GREEN sensor body and mates
with the 3-pin connector on the main harness marked with
a GREEN cable tie. Screw sensor all the way into hole of
flowmeter. Tighten 3/8” jam nut to secure sensor in place.
Uncoil flow sensor cable and carefully route it to meet the
main harness flow connector marked with GREEN tie. Align
connectors and press firmly together until locking tab clicks
into place. Secure cable with ties provided. See Illustration
5and MT-3405F II Wiring Diagram on page 8.
Note: Sensors with GREEN bodies can be used for either
SPEED or FLOW but not for RUN/HOLD.

If you have a positive displacement pump or a centrifugal
pump capable of generating excessive pressure, you must
install a pressure relief valve and adjust it to a safe maximum
pressure. If a positive displacement pump is operated without
a pressure relief valve, damage may result to pump or other
plumbing component. See Illustration 6.
Range Adjust Valve
With oversized pumps, it may be necessary to install a range
adjust valve. The range adjust valve will reduce the pump’s
output to the rest of the system. Adjustment of this valve is
covered in the Pre-Field System Checkout, page 32. See
Illustration 7.
Servo, Throttling Valves
For BYPASS installations, the servo valve installs in an
unrestricted return line to the inlet of the pump or directly
into the tank. The console must be calibrated for bypass
operation, see Calibration section. 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 8. 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 on pages 32for proper valve
adjustment procedure.
The servo valve connects directly to the 3-pin connector on
the main harness. If more length is required, use a 3-pin W/P
extension cable of the appropriate length.
IMPORTANT NOTE: If using the MT-3405F™ II with an old
style Micro-Trak servo valve, the valve voltage must be
set to 8 volts. See Special Calibration Valve Voltage section
on page 22.
NOTE: The servo valve may be installed in the main spray
line as shown in Illustration 9. For in-line installations, you
will need to calibrate the system for INLINE operation,
see page 33.

If your relief valve does not have flow-through port, you
must add a “T” fitting. NOTE: To assure a good connection
and avoid corrosion, coat electrical connections with
silicone grease.
The relief valve connection can be used to relieve system
pressure when section valves are turned off. When all the
sections are turned off, or when HOLD is selected with
the master switch, +12VDC is energized at the relief valve
connection and the relief valve opens. Use Illustration on the
right 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.
Electrical connection:
Locate the end of the violet wire under the heat shrink on the
14320 cable. See Illustration 10 below. Pull the violet wire out
of the wrap, crimp on a connector, and connect this lead to the
relief valve positive terminal. Connect the other terminal on the
relief valve to ground.

The MT-3405FTMII is capable of displaying information in
English or standard Metric measurement. The MT-3405FTMII
is shipped from the factory programmed for English. NOTE:
The following procedures will also load factory default
calibration values. To simply change units without
loading defaults, see the “Special Calibration” section.
METRIC
• You must be in HOLD or have all booms OFF to enter
Cal. To activate the Metric mode, turn power OFF
and place the rotary switch at “AREA.” Hold down
both the “CAL” and “-” keys and turn power ON. See
Illustration 11. The console will display LOAd. Once
LOAd is displayed, release the two keys. To “lock-in”
Metric mode you must enter and exit calibration. Press
and hold the CAL key until “CAL” icon appears on the
display. The console is now in calibration and Metric
mode is selected. Exit CAL by pressing and holding
the “CAL” key until CAL disappears from the display
(approximately 1 second).
NOTE: You must exit CAL to lock in Metric units.
ENGLISH
• You must be in HOLD or have all booms OFF to enter
Cal. To activate the English mode, turn power OFF and
place the rotary switch in the VOLUME position. Hold
down both the “CAL” and “-” keys and turn power ON.
The console will display LOAd. Once LOAd is displayed,
release the two keys. To “lock-in” English mode you
must enter and exit calibration. Press and hold the CAL
key until “CAL” lights on the display. The console is
now in calibration and English mode is selected. Exit
CAL by pressing and holding the “CAL” key until CAL
disappears from the display (approximately 1 second).
NOTE: You must exit CAL to lock in English units.
Entering Calibration Values
To enter or change any of the system’s calibration values,
you must enter calibration mode. To enter calibration
mode, STOP the vehicle, turn all booms OFF or put the
console in HOLD and press and hold the CAL button until
the “CAL” icon appears (approximately one second). (NOTE:
Calibration may be entered while moving, but it is not
recommended 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 by the WHITE
labeling on each side of the rotary selector. All values are
entered and adjusted using the “+” and “-” buttons on the
front panel.
Note: TEST SPEED is NOT a calibration setting. It simulates
vehicle speed during Pre-Application System Checkout.
This procedure is described on page 33.
Hold the “CAL” key again for 1 second to exit calibration.
“CAL” will disappear from the display.
NOTE: You must exit CAL to save changes.

Your Micro-Trak flowmeter has been tested at the factory
and assigned a “FLOW CAL” value to make it operate
properly with the MT-3405F™ II console. This number
is printed on the plastic tagattached to the flowmeter.
See Illustration 13. This is a starting point only. If your
spray solution has a specific gravity or viscosity that is
different than water, flowmeter calibration should be done
for the specific solution (Please refer to Fine-Tuning Flow-
meter Calibration in Appendix C on page 45.)

TARGET RATE: Enter the value for the desired target
application rate in gallons per acre (liters per
hectare) or lbs. of N per acre (kgs of N per
hectare). This is the application rate that the
console will lock onto when operating in
AUTO.
TARGET
RATE RATE
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
or decrease your
application rate in
one-gallon (liter) or
lb. (kg) increments
during operation in AUTO. To disable this feature, simply
enter “.0” for a value.
ADJUST
RATE TANK
MIN FLOW: The purpose of this calibration value is to
prevent the system from applying below the recommended
minimum rate for the nozzles. 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 of your spray
application. FOR EXAMPLE: If the minimum
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: Over-application may occur with
MIN FLOW set if ground speed is too slow.

WIDTH: Enter the effective working width, in inches (meters)
for the boom section currently shown on the display. It is
simplest to start with all booms ON and then turn each boom
OFF, from left to right,
after calibrating the
width. Note that the
system must be in
RUN (not HOLD) to display boom numbers.
Repeat this procedure for each boom
section. Enter a value of “0” (.000) for any
unused boom sections.
Your “working” width per boom section will be the number
of nozzles on the boom section times the nozzle spacing in
inches (mm). For example, if you have 7 nozzles spaced at 20
inches, the working width of the boom section is 140 inches.

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 calibration.
Any number between 10 and 15 (255 mm to 380 mm) is a
good starting value.
NOTE: For fine-tuning the SPEED CAL value, see Appendix B
on page 44.
Illustration 15
To determine SPEED CAL, measure the distance of
one complete wheel revolution and divide by the
number of magnets installed.
For the console to calculate the correct speed and
measure distance accurately, the circumference of the
sensor-equipped wheel must be entered. Determine the
circumference of the sensor-mounted wheel to the nearest
tenth of an inch (tenth of a centimeter) with the following
method:
METHOD
Mark the tire with a piece of chalk and measure the distance
traveled on the ground for one complete revolution. See
Illustration. For improved accuracy, it is recommended
that you perform this function in field conditions, measure
several revolutions, and take the average.
Divide the measured revolution by the number of magnets
installed to get your starting SPEED CAL calibration value.
Once calibration of the system is complete, this number
should be fine-tuned for optimum accuracy.
For fine-tuning the SPEED CAL value, see Appendix B on page 44.
TEST SPEED: Test speed is a built-in ground speed simulator
that is used in performing pre-field checks. When a typical
operating speed is entered, the MT-3405F II will
respond as if you were actually driving that
speed. It allows you to simulate your spraying
application with water, while remaining
stationary, to make certain that all of the
equipment is operating
properly and that your
sprayer can actually
perform the intended
application. Test speed will not accumulate Distance or Area
measurements. (The CAL indicator flashes to remind the user
that TEST SPEED mode is active.) TEST SPEED is cancelled by
exiting CAL.
