Mounting the Display Console
Selectamountinglocationwhichseemsmostworkable,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.

Electrical Installation
The MT-3405 F must be connected to a 12-volt DC electrical
system. Power is connected directly to the battery. The MT-3405
F 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 F 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.
NOTE: For negative ground systems ONLY.

PLEASE NOTE: If you have purchased a radar speed sensor,
disregard the section on magnetic speed sensors and
install the radar as described in the instructions packed
with the unit. You will need to order an adapter cable to
connect the radar unit to the MT-3405F.
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.

• Mounting “L” Bracket
• Magnet Clips
• Magnets
• Cable Ties
Magnet Installation
NOTE: 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.

EXAMPLE IN ENGLISH/TURF UNITS
If your revolution measurement is 97 inches, dividing that
number by 20 gives you a value of 4.85. Rounding 4.85 up to
the nearest even number is 6. For this example, the minimum
number of magnets required is 6.
EXAMPLE IN METRIC UNITS
If your revolution measurement is 2.5 meters, dividing that
number by .5 gives you a value of 5. Rounding 5 up to the
nearest even number is 6. For this example, the minimum
number of magnets required is 6.
Refer to the diagram to the right 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.
Attaching Magnets
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 F 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.

Installation (cont)
Connecting the Speed Sensor
The speed sensor cable has a GREEN sensor body and mates
with the speed 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 speed cable
from the console. The speed sensor and the flow sensor
are identical, but must be connected to the proper harness
connector.
INSTALLATION NOTE: For speed sensor installations on
implements, order the appropriate length 3-pin extension
cables to connect the speed sensor and speed connector
on the cable.
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.
IMPORTANT NOTE: See complete System Diagram on page 7.

Speed Sensor Options
In addition to the standard Hall-effect magnetic speed
sensor, the Agri-Cruise IITM may be interfaced with a variety
of other speed sensing equipment, such as the options listed
below.
Astro 5 GPS Speed Sensor
The Astro 5 is an easy-to-install economical alternate to radar
speed sensors. The sensor converts GPS signals to a pulsed
speed signal, providing an accurate speed input even in
conditions where radar does not perform well. The Astro II is
NOT compatible with the with the Agri-Cruise IITM.
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.

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 5.
NOTE: Save plastic plugs to protect flowmeter during
storage.
Illustration 5
Flow Sensor Cable Installation
With the flowmeter in place, install the flow sensor cable
(GREEN body).
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
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 6.
IMPORTANT NOTE: See page 8 for complete wiring

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 7.
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, page 30. See Illustration 8.
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 38.

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.

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.
IMPORTANT NOTE: See complete wiring diagram on page 8.
NOTE: To configure your system using motorized ball
valves, see Appendix B.
RELIEF SOLENOID
Illustration 10
The relief valve is used to “dump” pressure when your 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.
With the relief valve installed, locate the violet wire (tied
back on flow/servo cable) and crimp a female terminal on
the violet wire and connect to relief valve terminal. Connect
other terminal on relief valve to ground.
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.

WIDTH
SUB AREA
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 14.

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 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: 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.

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 wheel
circumference value is the number shown
alongwith“CAL”onthedisplay.SeeIllustration

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).

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
17. 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 circumference (CIRC) calibration value.
