Introduction
MT-3405 M 5Boom Automatic Rate Control System
6
Your new MT-3405 M system is a high-performance controller,
designed for superior control of product applications with
features to help you manage your operation efficiently. From
the large liquid crystal display and user-friendly controls to
the Windows-compatible Utilities Software, the system is
designed with the operator in mind. Some of the built-in
features are described in the following paragraphs.
MODULARITY
Installing your MT-3405 M is cleaner and easier since only
a single four-wire cable is required to connect sprayer
functions to the console. The sealed electronic module has
inputs for flow, run/hold, speed and (optional) pressure
sensors. In addition, it has outputs for flow regulation, relief,
and up to five boom shut-off valves. The system easily adapts
to most solenoid- or motor-driven boom shut-off valves.
INTEGRATED CONSOLE
The MT-3405 M console houses all operator controls in a
single weather-resistant case. Battery and sprayer cables are
equipped with environmental connectors while a standard
serial cable connection is provided for easy VRT hook-up.
IMPROVED ADAPTIVE CONTROL
The MT-3405 M system uses advanced control methods to
adapt to your applicator system automatically, completely
eliminating the need to “fine-tune” the console for best
performance. Adaptive control has always been included in
Micro-Trak controllers, and has been further refined in the
MT-3405 M.
FLEXIBILITY
The MT-3405 M can be configured to control liquid, NH3
or properly equipped dry material applicators. The MT-3405
M 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.
UTILITY SOFTWARE CD
In addition to the operator’s manual in PDF format, your
CD has the Utility Software program. This program uses
a calibration “wizard” to direct the operator through the
MT-3405 M calibration process and automatically sets up
calibration for various types of systems. Information for
different applications may be stored in files for convenient
re-entry into the console. Calibration settings may be printed
for manual entry into the console. Alternately, the MT-3405
M may be connected to the PC for calibration downloading
as well as uploading field data and upgrading the MT-3405
M’s Flash program.
RS232 SERIAL INTERFACE
The MT-3405 M serial interface allows the console to be
linked to most desktop or laptop computers. This serial link
can be used to calibrate or reprogram the console using the
Utility Software package. It can also be used with appropriate
software such as Farm Works SiteMate™to accomplish variable
rate application (VRA), or as a data logger to download
accumulated data and calibration parameters to the PC at
intervals commanded by the PC program. The MT-3405 M
system also offers VRA shut-off control for individual booms.
TIME TESTED MICROTRAK FEATURES
An (optional) run/hold sensor automatically turns off the
entire sprayer when equipment is raised, minimizing operator
workload at a critical time. The ADJUST RATE feature allows
the operator to change the application rate by a preset
amount with the push of a button. An electric relief valve is
recommended for systems that can exceed the permissible
pressure when all booms are off. The MINIMUM FLOW
setting maintains a good spray pattern at low speeds. Semi-
automatic calibration (FINETUNING) allows exact calibration
of speed and flow sensors with a minimum of effort.
NOTE TO THE USER
The MT-3405 M is written using English units of measure, but
is capable of operating in Metric and Turf units as well. The
“Units of Measure” chart shows the units of measure for each
function that is controlled by the MT-3405 M. This chart is
shown several times throughout the manual, and is referred
to by the “+” sign.

Illustration 2 Back of console
Route console cables so
that the connectors are
lower than the console.

The MT-3405 M must be connected to a 12-volt DC electri-
cal system. Power is connected directly to the battery. The
MT-3405 M 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 3. 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 3. Be sure there is good metal-to-metal con-
tact.
NOTE: For negative ground systems ONLY.
Mounting the Module
INSTALLING THE BRACKETS
To install the module brackets, crimp a terminal to the blue
ground wire. Fasten the brackets to the module as shown,
and install the crimped blue wire under one of the screws
holding the bracket to the module. See Illustration 4.
INSTALLING THE MODULE
Select a mounting location for the SC-3405 module that
will provide enough cable to reach both the console and
each of the plumbing components. Fasten the module
and brackets to the equipment frame or other equipment
location using bolts or self-tapping screws. Cut the blue
wire to a suitable length. Crimp on terminal and connect
to good chassis ground. See Illustration 4.
Follow the wiring diagram shown on page 14. Use extension
cables to connect the 4-pin W/P shroud to the 4-pin W/P
tower of the console.
INSTALLATION NOTE: To avoid non-warranty moisture
damage to the module, route module cables so that the
connectors are lower than the module.

Your MT-3405 M 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.
To Chassis Ground

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:
Non-driven wheel on tractor, vehicle or implement. This1.
is less susceptible to errors resulting from wheel slip.

Magnet
Tractor, vehicle or planter drive shaft. This type of2.
mounting is recommended for trucks, four-wheel drive
tractors or other equipment that has poor or no access
to a non-driven wheel.
Magnets
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), two magnets are generally
sufficient.
The magnets provided by Micro-Trak are marked with a
dashed line on the SOUTH pole side of the magnet. See
Illustration 5.
NOTE: 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. The long
dimension of the magnet must wrap around the hub or shaft.
Mount the second magnet with the NORTH pole side facing
toward the hub or shaft. See Illustration 6.
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 7.
Attaching Magnets
Refer to Illustration 8 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.

Mounting Speed Sensor
Use bolts or self-tapping screws to mount the bracket so
that the sensor is aligned directly over the magnet. (Bracket
may be attached by other means such as welding.) When
the wheel or drive shaft begins turning, a speed impulse is
sent to the MT-3405 M 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.
See Illustration 9.
CAUTION: To ensure that no console damage occurs,
disconnect all system cables before welding.

Speed Sensor Installation (cont)
INSTALLATION NOTE: The MT-3405 M system 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) exiting the rear of the console. Using this
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 connection
point on the module. 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.

connection point will disable the connection point on the
module. For speed sensor installations on implements, it
may be more practical to use the speed connector exiting
the SC-3405 Module. A dust cover should be installed on
the unused speed connection point.

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 ½” - 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 11.
NOTE: Save plastic plugs to protect flowmeter during
storage.
Installing Flow Sensor Cable
With the flowmeter in place, install the flow sensor cable
(GREEN body). See Illustration 12.
Screw sensor all the way into hole of flowmeter. Tighten 3/8”
jam nut to lock sensor in place.
Uncoil flow sensor cable and carefully route it to meet
the module flow cable connector marked with GREEN tie.
Align connectors and press firmly together until locking
tab clicks into place. Secure cable with ties provided. See
Illustration 13.

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 maxi-
mum pressure. If a positive displacement pump is operated
without a pressure relief valve, damage may result to pump
or other plumbing component. See Illustration 14.
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 checkout, pages 31-32. See
Illustration 15.

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. See Illustration 16.
Locate the flow/run/hold cable harness and connect to the
mating (2-pin) connector with the NATURAL tie . Connect the
blue chassis ground wire to a good frame ground. Make sure
there is good metal-to-metal contact.
NOTE: The console display area for pressure will be blank
until initial nulling is complete.
To null the pressure sensor:
Place the1. RUN/HOLD switch in HOLD.
Turn the rotary dial to2. PRESSURE.
Press and hold the “ - ” switch for three seconds. A “0”3.
should show on the display.
NOTE: The pressure offset can be re-nulled if a new sensor is
installed, or at any time, but the display cannot be blanked
once it is set. (In other words, if the sensor is removed, the
pressure display will still show a value, not blank).
Pressure Sensor

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 17. 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 from the module to the
3-pin W/P connector (NO tie). 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
Appendix C.
Relief Valve
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 18) 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 2-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 19.
NOTE: To assure a good connection and avoid corrosion,
coat electrical connections with silicone grease.

NOTE: The servo valve may be installed in the main spray
line (in-line). For in-line use, you will need to calibrate for
in-line (see Calibration section). Failure to set for in-line will
result in backwards operation of the servo valve.

with the YELLOW cable tie near the connector. Boom five (5)
connects to the mating connector with the GREEN cable tie
near the connector. See Illustration 20.
NOTE: To configure your system using 2-wire motorized
ball valve shut-offs, remove jumper cover from the
2-conductor cable exiting the back of the MT-3405 M
console. If using this system with 3-wire or 4-wire motorized
ball valve shut-offs, see Appendix B.
Plumb boom valves with flow-through port as shown.
Boom valves of differing designs may require a “T” fitting.
See Illustration 20. 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 cables. Crimp the insulated female
quick disconnect terminals provided with the cables to
both wires. (If valves have wires, crimp mating 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 connec-
tors on the module. Boom one (1) connects to the mating
connector with the BROWN cable tie near the connector.

Rockshaft Control Lever Mounting
The MT-3405M system provides two connection points for
the run/hold. For run/hold installations in the cab or near
the control console, it may be more practical to use the local
access connector (GRAY tie) exiting the rear of the console.
For run/hold sensor installations on implements, it may be
more practical to use the run/hold connector at the module.
A jumper cover must be installed on the unused run/hold
connection point or the system will always be in HOLD and
the boom control valves will not function.
The run/hold sensor cable has a black body and a GRAY tie
near the 3-pin M/P connector and mates with the module
cable having a GRAY 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 module. The run/
hold sensor has a BLACK body. DO NOT use a speed/flow
sensor (GREEN body). See wiring diagram on the previous
page. A jumper cover should be installed on the unused run/
hold connection point.
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 bring-
ing 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.
NOTE: Do not apply power to run/hold wires.
