Installation

Mounting the Display Console

Select a mounting location which seems most workable,
and that best fits your needs. It should be con ve nient to
reach and high ly vis i ble to the op er a tor. DO NOT IN STALL

IN A PO SI TION THAT OB STRUCTS THE VIEW OF THE ROAD
OR WORK AREA. Whenever pos si ble, avoid lo ca tions that

expose the con sole to direct sun light, high tem per a ture,
strong chemicals or rain.

Place the mounting bracket in the selected lo ca tion, mark
holes, drill 1/4” (7mm) holes and mount bracket with bolts,
lock- wash ers and nuts pro vid ed. (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 elec tri cal 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 elec tronic mem o ry which does
not re quire a con stant supply of pow er to re tain daily totals or calibration val ues. The
advantage with this type of memory is that it conserves battery power and will not
dis charge 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.

Speed Sensor Installation

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.

Magnets

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.

Locate the following parts:

• Speed sensor cable (green body)

• Mounting “L” bracket

• Magnets

• Cable ties

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.

English or Turf (inches)

Wheel Circumference 40 80 120 160 200

Number of Magnets 2 4 6 8 10

Metric (cm)

Wheel Circumference 100 200 300 400 500

Number of Magnets 2 4 6 8 10

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.

For proper operation, the
magnets must be evenly
spaced around the wheel or
drive shaft. The magnets must
be at least 1” apart.

Attaching the Speed Sensor

Sensor assembly must not

45° from perpendicular

Illustration 3

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.

Speed Sensor Options

NOTE: In addition to the standard Hall-effect magnetic
speed sensor, the MT-3405F II may be interfaced with
a va ri ety 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 re quired for
proper interface.

SEE APPENDIX I FOR LIST OF ADAPTER CABLES FOR RADAR.

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.

Mounting and Plumbing Flowmeter

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
flow me ter. Tighten 3/8” jam nut to secure sen sor in place.

Manual Pressure Relief Valve

If you have a positive displacement pump or a cen trif u gal
pump capable of generating excessive pressure, you must
in stall a pressure relief valve and adjust it to a safe max i mum
pressure. If a positive dis place ment pump is operated without
a pressure relief valve, damage may re sult 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. Ad just ment 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 32 for 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.

Installation (cont.)

Electric Relief Valve

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.

Illustration 10

14320 Cable

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.

Care & Maintenance of your MT-3405FTM II Console

Store the console in a cool dry location if it will not be used for an extended period of time, such as during the off-season.
As with any electronic equipment, use care in cleaning so that water or other liquids do not enter the case.
Thoroughly rinse Flowmeter with clean water, install plastic shipping plugs and keep from freezing.

PRECAUTIONS

• Do not exceed rated input pressures on flowmeters or other system components.

• Avoid excessive liquid temperatures - some components could be damaged by liquid temperatures exceeding 130°F (55°C).

• Some chemicals could damage certain non-metallic or nylon parts, depending on your system. If you are in doubt,
contact the chemical manufacturer.

• You must be in HOLD or have all booms OFF to enter
Cal. To activate the Metric mode, turn power OFF
and place the ro ta ry switch at “AREA.” Hold down
both the “CAL” and “-” keys and turn power ON. See
Il lus tra tion 11. The con sole will display LOAd. Once
LOAd is displayed, release the two keys. To “lock-in”
Metric mode you must enter and exit cal i bra tion. Press
and hold the CAL key until “CAL” icon appears on the
display. The con sole is now in cal i bra tion and Metric
mode is selected. Exit CAL by pressing and holding
the “CAL” key until CAL disappears from the display
(ap prox i mate ly 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 ro ta ry switch in the VOLUME position. Hold
down both the “CAL” and “-” keys and turn power ON.
The con sole will display LOAd. Once LOAd is displayed,
release the two keys. To “lock-in” English mode you
must enter and exit cal i bra tion. Press and hold the CAL
key until “CAL” lights on the display. The console is
now in cal i bra tion 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
rec om mend ed to attempt calibration while the vehicle is
mov ing.) 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
po si tion. Calibration positions are identified by the WHITE
labeling on each side of the rotary selector. All values are
entered and adjusted using the “+” and “-” but tons 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.

Calibration (cont)

Drive Shaft Speed Sensor Calibration

Determining the SPEED CAL

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 fol low ing
method:

METHOD

Mark the tire with a piece of chalk and mea sure the distance
traveled on the ground for one com plete rev o lu tion. 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.

Illustration 15

To determine SPEED CAL, measure the distance of

one complete wheel revolution and divide by the

number of magnets installed.

Factory-Loaded Calibration Values

NOTE: If you have mounted the magnetic speed sen sor 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 ra tios, 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 cal i bra tion.

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.

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

Operation

General

Make sure your system is properly calibrated before
beginning to apply product. We also recommend
completion of the Pre-Field System Checkout described on
pages 39-40 prior to beginning any field operations.

Press the ON/OFF button to turn the console on. After
displaying the hours of operation and software version, the
console will start normal operating mode.

The MT-3405F™ II can be operated in Manual (MAN) or
Automatic (AUTO) mode. In either mode, the right-hand
display will always show the Application Rate (except
when in HOLD or when displaying error messages, see
Troubleshooting section starting on page 33). The left hand
display will show data as selected by the rotary switch.

Manual Operation

The manual mode is used when the operator wants to
manually control the servo valve using the “+” and “-” keys,
and thus the application rate. The application rate (gal/
acre or liter/hec) will vary depending on ground speed.
Use the AUTO/MAN button to select MANual mode (“MAN”
icon will be displayed).

IN HOLD: If the console is in HOLD, or if all Boom Valves

are OFF, the “+” and “-” buttons will not control the servo
valve unless the rotary switch is in the VOLUME/MINUTE
position. In that position only, the servo valve can be
adjusted without any boom valves on. This can be useful
for system pressure tests, etc.

IN RUN, WITH SPEED SIGNAL: If the system is in RUN,

with at least one boom valve ON and there is a speed
signal, the “+” and “-” buttons can be used to adjust the
servo valve with the rotary switch in any position except
TANK, VOLUME, and AREA and the application rate can be
monitored on the right-hand display.

IN RUN, NO SPEED SIGNAL: If there is no speed signal,

“no SPEEd” will flash in the right-hand display and the
Application Rate will be invalid. The “+” and “-” buttons will
adjust the servo valve if the rotary switch is in the VOLUME/
MINUTE position, and the flow rate (GPM or LPM) can be
monitored.

Automatic Operation

When the Automatic mode is selected, the console will
control the servo valve to maintain the desired application
rate (GPS/LPH) when the vehicle speed changes or when
booms are turned on or off. Press the AUTO/MAN button to
select AUTOMATIC mode; the AUTO icon will appear in the
display.

To operate the system in AUTOMATIC mode, turn on the
desired booms, toggle the RUN/HOLD switch to RUN, and
drive. IMPORTANT NOTE: In AUTO mode, when no speed
signal is available, the system automatically turns all booms
off. “no SPEEd” will flash in the right-hand display until the
vehicle starts moving, then the console will turn the booms
on and the Application Rate will be displayed in the right­hand display. The system will automatically adjust the servo
valve to maintain the calibrated TARGET RATE (GPA/LPH).

ON-THE-GO “DELTA” RATE ADJUSTMENTS (ADJUST
RATE) To adjust the target application rate on-the-go,

each time the “+” or “-” buttons are pressed, the TARGET
RATE will be increased or decreased by the amount of the
ADJUST RATE which was entered in calibration. Example:

calibrated TARGET RATE = 10.0 GPA and ADJUST RATE =

1.0 GPA, pressing the “+” key once will increase the target
rate from 10.0 to 11.0. The rate display will momentarily
show the new target rate of 11.0 and then show the actual
application rate. Pressing the “-” key once will decrease
the target from 11.0 to 10.0. NOTE: When you “DELTA”
the target rate, the display will momentarily show you
the new target rate and then resume showing the actual
application rate. The new target rate is maintained until
further adjustments are made using the “DELTA” feature
or calibration changes occur, or if the unit is turned off.
Important: to use the DELTA feature, the console must be
in AUTOMATIC mode and the rotary switch can be in any
position except TANK, VOLUME, or AREA.

IN HOLD: If the system is in AUTO mode and in HOLD or
all booms are off, the “+” and “-” buttons will adjust the
TARGET RATE with the rotary switch in any position except
TANK, VOLUME or AREA; CAUTION: we recommend that
the rotary switch is in the RATE position, because that is
the only position where the new TARGET RATE is displayed
while in HOLD. In RATE position, the left-hand display will
momentarily display the new TARGET RATE, then will revert
to .00, because all the boom valves are off so there is no
product being applied.

Operation (cont)

Automatic Operation (cont)

USING THE TANK COUNTER

With the rotary switch in the TANK position, the left-hand
display shows the amount remaining in the tank. If a FILL
TANK SIZE (tank full) number has been entered in Special
Calibration, the “AUTO FILL” feature is active; this feature
allows the TANK counter to be quickly reset to a full tank
amount by simply pressing the “+” button with the rotary
switch in the TANK position. The “-” button can be used to
reduce the tank counter, but any press of the “+” will set the
counter to the calibrated FILL TANK SIZE value.

If no TANK VALUE has been entered in calibration, the tank
counter can still be used, but the counter must be manually
adjusted when filled, by pressing and holding the “+”
button until the desired value is reached.

WARNING DEVICE

The console is equipped with a RED warning light. The
light will automatically turn on and flash when the actual
application is plus or minus 10 percent of the calibrated
target rate, or if the TANK alarm feature is activated and
the tank is below the set point (display will also flash “FILL”
message). If the light stays on while in AUTO, refer to the
troubleshooting section of this manual. The RED warning
light will also be illuminated when calibration mode is
active on the console.

AUDIBLE ALARM

The Audible Alarm is activated for the following conditions:

• The calculated Tank level is below minimum level
(TANK ALARM SET POINT).

• Float switch is continuously active for 15 seconds or
more.

• The Application Rate Error is greater than 10% for 3
seconds (continuously) after the Auto Delay and Start
Up time have completed and the console is in AUTO,
and the Ground Speed is above the Alarm Minimum
Speed.

EMERGENCY STOP

When in AUTO and in RUN with one or more Booms on and
the Speed is greater than zero, if the Flow signal ever stops,
the servo will run to fully open. If Flow remains stopped
for 5 seconds or more, it will automatically reduce the flow
to a minimum (run Servo for 4 seconds). “EStOP” will then
display to notify the user of the Emergency Stop. The flow
remains off (or reduced) and AUTO control will remain
disabled until the system goes into HOLD, power is cycled
or CALIBRATE is entered. The Emergency Stop feature helps
protect against “chemical spills” or over-application if the
Flow signal is lost.

TANK ALARM

If a TANK SET POINT (tank low) number has been entered
in Special Calibration, the TANK ALARM feature is
active. When the tank counter value drops below the
TANK SET POINT, the red warning light will flash and “FILL”
will flash on the left-hand display. The “FILL” message
will flash no matter what position the rotary switch is
in. Adjusting the tank value to a value greater than the
SET POINT will turn the alarm off.

Operation (cont)

Resetting System Counters

The AREA, DISTANCE and VOLUME counters maintain a
running count during operation regardless of the position
of the rotary switch. When any of these counters reach their
maximum capacity, or when you want to start a new count,
the value may be reset to zero by performing the following
routine. Counter pairs may be reset independently of other
counter pairs.

1. Turn the booms OFF or put the system in HOLD.

2. Turn the rotary switch to the counter to be reset.

3. To reset distance turn the rotary switch to DISTANCE
and simply press and hold the RESET button until the
display reads zero. The display will show the word
CLEAr during this process, and will show 0.0 when
reset to zero is complete.

4. To reset the volume and area counters; there are three
independent AREA counters, paired with three VOLUME
counters. The active pair of counters is indicated by the
small numbers in the lower right area of the display (1,2,
or 3) when the rotary switch is in the AREA or VOLUME
position. Select the pair of counters you want to use
by pressing the “+” button. The small number will
increment each time the “+” button is pressed (from 1
to 3, then rolls back to 1). DO NOT attempt to select the
counter number by using the “-” button, because that
will clear the active pair of counters if held for 1 second.
If the “-” button is accidentally pressed, the console will
display “CLEAr” to alert the user that the counters will
be cleared. If the user continues to hold the “-” button
for 1 second “CLEAr” will disappear and be replaced by
.0, indicating that the selected pair of counters has been
cleared.

Clearing Counters

When the desired counter number is displayed, press the
“-” (RESET) button and “CLEAr” will be displayed. NOTE:

holding the “-” (RESET) button for 1 second will clear both
the #3 AREA counter and the #3 VOLUME counter whether
the rotary switch is in the AREA or the VOLUME position. If

the “-” button is released before 1 second has elapsed, the
counters will not be cleared and the “CLEAr” message will
be replaced with the previous total.

Troubleshooting (cont)

General

All MT-3405F™ II consoles, flowmeters and servo valves are
tested prior to packaging, so unless there has been damage
in shipment you can be confident that everything will be
operational when you receive it.

However, if you do encounter a problem that appears to be
related to equipment failure, PLEASE DO NOT OPEN THE
CONSOLE. Your system is protected by a warranty, and
Micro-Trak will gladly correct any defect.

Many problems are the result of mistakes in installation
or operation. Before returning any parts for service,
carefully check your installation and review the operating
instructions. For easy-to-follow guidelines, refer to the
troubleshooting section which follows.

CONSOLE APPEARS DEAD

Using your test light, check for 12 volts at the power source.
Also check for damaged power cable or reversed terminals.
(Console requires 12 volts for proper operation). Check
connections of ignition or power switch.

SPEED IS ALWAYS ZERO OR ERRATIC

Check for properly calibrated wheel circumference.

Review speed sensor installation. Check for proper
mounting, alignment and spacing of speed sensor in
relationship to magnet assembly. Make sure magnet
polarities are alternated. Also check cable for breaks or
incomplete connection. For more suggestions on solutions

to speed problems, see Hall-effect sensors and console
inputs on pages 35-36.

DISTANCE COUNT IS INACCURATE

Wheel circumference was incorrectly measured or entered.
Review calibration, re-adjust and test.

AREA COUNT IS INACCURATE

Implement width or wheel circumference was measured
incorrectly or programmed incorrectly. Go back through
the original procedures, make changes, and test for acre
(hectare) count again. (Make sure no width is entered for
unused booms.) Verify accuracy with formula:

Acres = Distance x Width in feet/43560
Hectares = Distance x Width in meters/10,000

NO READOUT OF GALLONS LITERS, OR GALLONS
LITERS PER MINUTE

Check to see that the sprayer pump and equipment are
operating properly. If liquid is moving through the line,
check the flow sensor to be sure it is screwed all the way
into the flowmeter.

material may be lodged in the flowmeter.

BOOMS SHUTOFF

If you are in AUTO with no speed, the booms will shut-off.

TOTAL LIQUID USED IS INACCURATE

This may result from an incorrectly-entered “FLOW CAL”
value. Check the number stamped on the flowmeter tag,
and be sure this is entered in the console’s “FLOW CAL”
position. If the meter has been used for some time, wear
may have changed the Flow Cal value. See Fine-Tuning

Flowmeter Calibration in Appendix C.

Check the mounting position of the flowmeter. With lower
flow rates, the meter should be mounted vertically. Also
check to see that the flow sensor is screwed all the way into
the flowmeter.

Other causes may be inaccurate sprayer tank markings, a
flow rate too low to register, or foreign material lodged in
the flowmeter.

CONSOLE IS ERRATIC IN OPERATION

If you have a two-way radio, it may be mounted too close
to the console. Keep all MT-3405F™ II cables away from the
radio, its antenna and power cable.

Ignition wires may be causing the console to malfunction.
Keep MT-3405F ™ II cables away from ignition wires, or
install ignition suppressor.

Reroute all cable away from electric solenoids, air
conditioning clutches and similar equipment.

Check the VALVE SPEED calibration number in Special
Calibration. If the RATE tends to overshoot or oscillate, the
VALVE SPEED setting may be too high for the control valve
being used; reduce the VALVE SPEED setting by 1 (range is

-2 to +3).

DISPLAYED MEASUREMENTS DO NOT MAKE SENSE

The console may be in the incorrect measurement mode
(English or metric). See page 24 for instructions.

DISPLAY READS “OFL” OR “99999”

DISTANCE, AREA, and VOLUME counters read OFL or 99999
when they have exceeded their maximum count. Reset to
zero to resume counting.

SYSTEM OPERATION CONTROL IS SLUGGISH IN
AUTOMATIC MODE

Check the VALVE SPEED setting in Special Calibration. If
using a slow valve (4 seconds or more, open to close)
increase the VALVE SPEED setting.

Check to see that a FLOW CAL number has been entered.
Also check cable for breaks or incomplete connection.

If the flowmeter is new or has not been used for a long
period of time, the turbine may be sticky. Flushing the
system out with water should make the turbine spin freely.

Flow rate may be too low to register a reading, or foreign

Troubleshooting (cont)

Checking Individual Components

CONSOLE

The only way to field test a console is to con nect it to a
harness on a vehicle with a known working console or
install it on an E-POP (Elec tron ic Point of Purchase) dis play
stand.

HARNESS

The harness can be checked using an ohm me ter or
continuity tester. The main wiring diagram shows the pin
out of all connectors. See page 9.

ELECTRICAL INTERFERENCE

Erratic operation of the system may be the result of
electrical interference from ignition wires or inductive loads
(electrical clutch, fan, solenoid, etc.). Always try to route
wires as far away from suspect areas as possible. If problems
occur, you may need to relocate the console and/or wiring
harness, or install a noise suppressor.

POWER

Check power source with the MT-101 tester or a test light.
If there is no pow er, trace cable toward battery look ing for
breaks. Also check any fuses or circuit break ers that supply
pow er to the console.

ACCESSORY POWER

The speed, flow and run/hold cables all have an ac ces so ry
power wire. Check for 12 volts between B (usu al ly white)
and C (usually black) of these con nec tors. If power is not
present, make sure the ac ces so ry pow er wire is not open
or shorted to ground or to another wire. If this wire has a
prob lem, the con sole may ex hib it erratic behavior or not
function at all.

RUN/HOLD HALLEFFECT SENSOR IF USED; REQUIRES

ADAPTER CABLE

Caution: Improper connection or voltage could damage the
Hall-Effect sensor. The Hall-effect sensor works similar to a
reed switch, but requires power in order to function. This
particular type of Hall-effect sensor “closes” when near the
south pole of a magnet and is otherwise “open”.

• RUN = “OPEN”

• HOLD = “CLOSED”

Ground pin C (black) and connect clean 12 volts to pin B
(white) of the Hall-effect sensor cable. Connect the positive
lead (red) of an ohmmeter or continuity tester to pin A (red)
and the negative lead (black) of the ohmmeter or continuity
tester to pin C (black) of the Hall-effect sensor cable.

Holding the tip of the sensor up to the south pole of a
magnet should result in a very low resistance (around 300
ohms). Taking the sensor away from the magnet should
result in a very high resistance (infinite).

MAGNETIC HALL-EFFECT SPEED AND FLOW SENSORS

Caution: Improper connection or voltage could damage
the Hall-effect sensor. The Hall-effect sen sor works similar

to a reed switch, but re quires pow er in order to func tion.
Also, this par tic u lar type of Hall-effect sen sor re quires al ter­nat ing magnetic po lar i ties in or der to switch. This means
that the north pole of a mag net will “open” the Hall effect
and the south pole of a magnet will “close” the Hall effect.

Ground pin C (black) and connect clean 12 volts to pin B
(white) of the Hall-effect sensor cable. Con nect the positive
lead (red) of an ohmmeter or con ti nu ity tester to pin A (red)
and the negative lead (black) of the ohmmeter or continuity
tester to pin C of the Hall-effect sensor cable.

Holding the tip of the sensor up to the north pole of a
magnet should result in a very high re sis tance (in fi nite),
while holding the tip of the sensor up to the south pole of
a magnet should result in a very low resistance (around 300
ohms).

VANSCO RADAR SPEED SENSOR

Carefully check your installation and operating instructions.
The following are tips for troubleshooting;

1. Disconnect the radar adapter cable from the console
harness

2. Check for 12 VDC between pins B and C of the main
harness connector (yellow tie). If not present, console
or harness may be defective.

3. Using a jumper wire (paper clip bent into a “U”), rapidly
short together positions A and C of the main harness
speed connector (yellow tie) several times. The console
should respond with some speed reading. If not, the
console or harness may be defective.

4. Reconnect the radar adapter cable to the main harness
speed connection (yellow tie).

5. Disconnect the radar from the radar adapter cable.

6. Check for 12 VDC between pins 1 and 3 of the radar
adapter connector. If it is not present but was present
in step 2, the radar adapter cable may be defective.

7. Using a jumper wire (paper clip bent into a “U”),
rapidly short together positions 2 and 3 of the radar
connector (round 4-pin) several times. The console
should respond with some speed reading. If not but
had a reading in step 3, the radar adapter cable may be
defective.

8. If system passes all above tests, the radar may be
defective.

28

Troubleshooting (cont)

Checking Console Inputs

If there is no response from any of the following tests, refer
to the main wiring diagram to locate the next connector
in line to ward the con sole and repeat the test at that con­nec tor. If there is a response at that connector, the problem
may be in the cable between the two connectors (or the
con nec tors themselves).

SPEED INPUT

Turn rotary switch to speed po si tion and dis con nect the
speed sensor (yel low tie) from the main harness. Check
for 12 volts between pins B (white) and C (black) of the
main harness speed cable (yellow tie). Using a clip lead
or other jumper wire (such as a paper clip bent in a “U”),
several times rap id ly short to geth er pins A (red) and C
(black) of the 3-pin connector (See Illustration 16). The
console should respond with some speed read ing.

Illustration 16

CBA

Three-Pin Connector

FLOW INPUT

Turn rotary switch to VOLUME/MINUTE and disconnect
the flow sen sor (green tie) from the main harness.
Check for 12 volts be tween pins B (red) and C (orange)
of the main harness flow cable (green tie). Using a clip
lead or other jumper wire (pa per clip bent in a “U”),
several times rapidly short together pins A (brown) and
C (orange) of the 3-pin connector. The con sole should
re spond with some flow rate reading.

REMOTE RUN/HOLD INPUT

Grounding the grey run/hold wire should turn on the
“HOLD” icon on the console’s left display, and display
“HOLD” on the console’s right display. Disconnecting
the grey wire should remove the “HOLD” messages
(console run/hold switch in “RUN”).

FLOWMETER

Shaking the Flowmeter end to end should pro duce a
“rattling” sound (shaft end play). Blowing in the meter from
either end should spin the turbine freely. If the turbine spins
freely but the meter will not register flow with a known
working sensor, the turbine may be defective. See Flow me-

ter Assembly and clean ing on page 46 and page 60-61 for
details.

SERVO VALVE CONTROL SIGNAL

With the console turned ON, put the console in MANUAL
mode, place the remote Run/Hold switch in the RUN
position and turn at least one boom switch to ON. Using
a voltmeter or simple test light, check from a good frame
ground to each of the servo wires on the main harness
connector. You should get 0 volts on each wire. Holding the
“+” button should cause one wire to pulse toward 12 volts
(light will pulse). Holding the “-” button should cause the
other wire to pulse toward 12 volts (light will pulse).

SERVO VALVE

The best way to test the servo valve is with a known
working console. Turn console ON, put the console in
MANUAL mode, place the remote Run/Hold in the RUN
position, turn the rotary switch to RATE and turn at least
one boom switch to ON. With the servo valve connected
to the servo valve lead on the main harness, holding the
“+” button should close the servo valve and holding the
“-” button should open the servo valve NOTE: assuming
you are in bypass configuration (provided the console has
passed the Servo Valve Control Signal test). The servo valve
should operate smoothly in both directions, from fully open
to fully closed.

You may also use a 12-volt battery or a 9-volt battery.
Connecting the battery to each terminal on the servo
valve should cause the servo valve to run in one direction.
Reversing the battery connections should cause the servo
valve to run the other direction. The servo valve should
operate smoothly in both directions, from fully open to
fully closed.

PLUMBING

Proper plumbing is a very important factor in obtaining
optimal performance from your MT-3405F™ II system. The
chart on the next page will help you determine what area of
the plumbing may be causing your problem. At this point, it
is assumed that your plumbing basically matches that of the
system diagram and that the servo valve and flowmeter are
known to be installed correctly and functioning properly. In
addition, make certain that you have selected and installed
the correct spray tips for the application, speed and spray
rate that you intend to maintain. Don’t forget the obvious
such as leaky fittings and hoses, pinched hoses and plugged
or worn nozzles. If you need more detail than the chart

provides, please refer to Plumbing Guidelines on pages
37-38.

Plumbing Guidelines

General

In order for your sprayer to function properly, it must be
correctly plumbed. The system diagrams (on pages 10

and 12) show the plumbing configuration that works best

with the MT-3405F™ II Sprayer Controller. This section will
explain the purpose of each component, list some problems
it can cause and recommend some possible solutions to
those problems.

A word about pressure drops: All hose, valves and fittings
(especially elbows) cause undesirable pressure losses.
Keep hoses as large as practical. Don’t use longer hoses
than necessary. Avoid bends whenever possible. Use as
few fittings as possible. Use full port valves or the next
larger size valve. Long hoses should be supported to avoid
sagging and kinking. Many spray tip manufacturers have
charts showing pressure drop for various fittings and hose
sizes.

Now let’s break the system diagram into five sections and
cover each one separately. The five sections are the pump
inlet line, the agitation line, the flowmeter (boom) line, the
servo line and the pump itself.

PUMP INLET

The hose connecting the tank to the pump should be at
least as large as the pump inlet port. In most cases 11/4” is
a good size. The valve in this line is for complete tank shut­off only and should always be fully open during operation.
If this hose is too small or the valve is partially closed, you
may not be able to reach your high end goals and pump
damage could occur.

AGITATION

The size of the agitation line is dependent upon the amount
of agitation required which is determined by the size of the
tank and the type of chemical being used. In most cases a 1”
hose is large enough.

SERVO

On the system diagram, the hose between tee “B” and the
servo can usually be 3/4” but 1” will also work. The hose
between the servo and tee “C” should be at least as large as
the servo. If these lines are too small, you may experience
little or no pressure adjustment.

FLOWMETER

The line feeding the flowmeter and the boom shut-off
valves should be at least as large as the flowmeter. The size
of lines going from the shut-off valves to each boom section
depends on the flow rate of each boom.

Re-calibrate

Set appropriately

Support or replace hoses

Adjust throttle and range valves

Larger hoses
Larger pump
Clean strainer

Lower valve response setting

Plumbing Guidelines (cont)

General (cont)

PUMP

The pump must have enough capacity to satisfy the
agitation, servo and flowmeter sections of the plumbing. To
determine if your pump is large enough you must add up
the gallons per minute of all three sections. The following
example will take you through the steps involved.

EXAMPLE

Let’s say our example sprayer has a 300-gallon tank
with a Spraying Systems 6290 SC-8 Jet Agitator. The
agitator uses 10.2 GPM at 40 PSI.

The sprayer has a 40’, three-section boom. Each section
is 160” with four tips at 40” for a total of 12 tips. We
plan to put on a 25 GPA at 5 MPH and in some areas
of the fields we may want to use the Delta feature and
increase our rate to 30 GPA and in other areas decrease
to 15 GPA. After checking the tip charts we find that a
TK-5 Floodjet has a range of 14.9 to 30 GPA at 5 MPH.
According to the charts, to get 30 GPA at 5 MPH with a
TK-5, the pressure must be 40 PSI. At 40 PSI a TK-5 will
spray 1.0 GPM. So, 12 tips at 1.0 GPM each is a total of
12 GPM.

Now let’s add everything together.

Agitation 10.2
Spray tips 12.0
Servo 5.0

27.2 Total GPM

The above addition shows that the system needs 27.2
GPM at 40 PSI. If we add a 10% margin (27.2 x 1 = 2.72
and 27.2 = 29.92), we have about 30 GPM. To be sure
we have enough volume, the pump should be able to
deliver 30 GPM or more at 40 PSI.

Valve Purpose and Adjustments

TANK SHUTOFF VALVE

The tank shut-off valve is for convenience only. It allows
you to work on the plumbing without draining the tank. It
should always be fully open during operation.

AGITATION SHUTOFF VALVE

The agitation shut-off valve is mostly for convenience. It
allows you to work on the plumbing without draining the
tank. It should normally be fully open during operation.

NOTE: Spraying Systems 144H DirectoValve has a
maximum pressure rating of 100 PSI (7 bar).

RANGE ADJUST VALVE

The range adjust valve is required when the pump is much
larger than necessary. When the range valve is opened,
some of the liquid will be bypassed around the pump to
avoid “overloading” the rest of the system. The setting of
the range adjust valve is determined by the throttle valve.

Start with the range valve fully closed and perform the
Pre-field System Checkout on pages 39-40. If the throttle

valve needs to be more than two thirds closed, open the
Range valve slightly and perform the Pre-field System
Checkout again.

THROTTLE VALVE (Bypass Plumbing)

The throttle valve limits your high end to maximize servo
performance. Start with throttle valve fully open and

perform the Pre-field System Checkout on page 39-40.

EXAMPLE

With the throttle fully open and servo fully closed, you
may be able to get 50 GPA at 5 MPH when you only
want 25 GPA. If you were to simply open the servo you
may be able to get down to 25 GPA, but if your speed
should drop to 3 MPH, the servo can’t open any farther
and won’t be able to maintain 25 GPA. Therefore, if you
leave the servo closed and close the throttle until your
high end has dropped from 50 GPA to about 30 GPA,
the servo has a greater operating range.

The throttle valve pictured in the system diagram is a
needle valve (Spraying Systems Type 12690 or 12795).
A ball valve may be used but is more difficult to adjust
and keep adjusted. Do not install a pressure regulator
or relief as a throttle valve.

If the throttle valve is closed too much, PSI may
fluctuate greatly in AUTO.

RELIEF SOLENOID VALVE

The optional relief solenoid will ensure enough bypass to
avoid excessive pressure when the boom valves are turned
OFF. See pages 21-22.

PRESSURE RELIEF VALVE

The pressure relief valve is used to avoid excessive pressure
when the booms are turned off. Start with the handle
screwed mostly out. Slowly bring pump up to operating
RPM (make sure pressure does not go too high). Put the
MT-3405F™ II in MAN and turn boom on. Hold adjust switch
to “+” for about 30 seconds to fully close servo valve. Turn
booms OFF. Now slowly screw handle in until maximum
desired pressure is reached. Lock handle in place with
locking nut or collar.

Before beginning actual spraying, perform the following
“Pre-field” procedure to ensure that your valve settings,
nozzle selection and desired speed range will allow the
MT-3405F™ II to provide the required application control.
This procedure should be repeated for each new nozzle
se lec tion and/or application rate. By performing all of
the steps listed below, you set up your system to allow
the MT-3405F™ II to perform at optimum level. Fill your
sprayer tank with clean water. DO NOT use chemicals
until the entire sys tem is completely checked out and
operating properly.

IMPORTANT NOTE: Most nozzles will maintain a good
pattern over a maximum speed range of two to one. (For
example, if your maximum speed is 12, your minimum
speed shouldn’t go below 6.)

NOTE: Pre-field System Checkout is a procedure performed
while the console is in the CAL mode. The Red WARNING
light will be lit during the procedure and “CAL” on the
display will be flashing.

Completely close range adjust valve (if installed), and ag i­ta tion valve (if installed). Completely open throttle valve
(must be installed).

Start vehicle and pump, bring the engine up to normal

Optional Speed Sensor Mounting on Drive Shaft

NOTE: This is an optional method generally used on
pickups or custom vehicles. It may also be nec es sary on
any other vehicles where ac cess to the wheels is lim it ed.
This in stal la tion requires a spe cial calibration procedure,
see page 27.

Determine the best location for the magnets on drive shaft
according to which is the most practical spot to attach
sensor mounting bracket. This position should be no more
than 12” (.30 meters) behind the front U-joint. For best
results, mount “L” bracket to transmission and mount
magnets on drive shaft as close to transmission as pos si ble.
This will en sure prop er alignment if drive train shifts under
heavy loading.

Two magnets are required for proper Hall-effect speed
sensor operation. Position them exactly opposite each other
(180 de grees apart). The polarity (north and south poles)
detect ed by the Hall-effect speed sen sor must alternate as
the shaft is turned. The magnets provided by Micro-Trak are
marked with a punched dashed line on the SOUTH pole side
of the magnet.

• Attach magnets onto drive shaft, one NORTH pole
side out and the other SOUTH (dashed) pole side out,
by wrapping ca ble tie around shaft and magnets.
Position each mag net so that its longest dimension
moves in the di rec tion of rotation. Pull cable tie tight
and trim off excess. An adjust able, non-magnetic
(stain less steel) band clamp may also be substituted.

• Attach sensor bracket to vehicle transmission
with bolts, lockwashers and nuts provided. See
Illustration below. (Use self-tapping screws if bolts are
not prac ti cal.) Use either the short or long end of the
brack et as a base. (Allow enough room be tween the
bracket and the magnets so that when prop erly spaced,
the tip of the sensor will extend 1/4” [7mm] or more
be yond the lock ing nut.)

• Turn one locking nut onto threaded sensor and in sert
sensor into large hole selected on mount ing brack et.
Turn on remaining locking nut. Set sensor to proper
distance from magnets (1/4” to 1/2”, or 6mm to 13mm).
When distance is set, tight en nuts to lock sensor in
place.

• Secure sensor cable to frame with cable ties. Place first

Appendix B - Fine Tuning Speed/Distance Calibration Val ue

(If system is set up for NH3 application, see page 58)

This procedure is used to verify the speed/distance
calibration. In order to achieve accurate measurements,
each step in this fine tuning procedure should be
performed as precisely as possible.

PREPARATION

• Once the system is fully installed and calibrated, se lect
a straight tract of ground that is similar to your ac tu al
field conditions and as level as pos si ble.

NOTE: Us ing a course with a different ground sur-

face, such as a hard-surface road, will re sult in dif fer­ent read ings than exact field con di tions.

• Measure a distance of 1000 feet (500 meters). Clear ly
mark the beginning and end points with flags or some­thing highly visible to the operator.

PROCEDURE

1. With the console turned ON, place the Run/Hold switch

in the HOLD position. The HOLD icon will be displayed.
Turn the rotary dial to the “DISTANCE” position. Be sure
the display shows 0. If not, reset the distance counter
by pressing and holding “RESET” until the display
returns to 0 (approximately one second). The word
CLEAr will be displayed when reset is pressed.

2. You are now ready to drive the measured course. Pick

a location on the vehicle to use as a marker for starting
and stopping the distance counting function (door
handle, mirror, step, etc.). You should begin driving the
course well ahead of the starting flag and drive past the
ending flag, using the Run/Hold switch to start and stop
the counting function. It is not recommended to start
from a dead stop at the starting flag and stop at the
ending flag.

3. Place the Run/Hold switch in RUN when the marker

on the vehicle passes the starting flag to activate
the distance counting function. The console display
numbers will increase, adding to the distance total as
you drive. Drive the pre-measured course and place
the Run/Hold switch in HOLD, when the marker on the
vehicle passes the ending flag, to stop the distance
counting function. The console display should read
“HOLD”. See Illustration to the right. Stop the vehicle in
a level and safe area and continue with this procedure.

4. With the rotary dial still at DISTANCE (SPEED CAL), press
and hold the “CAL” key for one second. Once the con­sole is in “CAL,” CAL and the speed calibration value
will be displayed. Momentarily press CAL and the word
CAL will begin to flash and the distance travelled will be
displayed.

5. When the display shows distance (“CAL” is flashing),
ver i fy wheth er the number displayed is the ex act dis­tance you drove (with in +/- 1 - 2 %). If not, press the
“+” or “-” key to ad just the fig ure to match the dis tance
you ac tu al ly drove. If the display reads too high, use the
“-” key to lower the dis played value. If the display reads
too low, use the “+” key to raise the displayed value.

6. When the number shown on the display match es (as
close ly as possible) the ac tu al dis tance driv en, you
have ar rived at the cor rect cal i bra tion val ue. If you
can not adjust the displayed distance to exactly match
the actual dis tance driven, adjust the figure as close
as possible to the actual distance. You may check the
calibration number by momentarily pressing CAL. The
word CAL and the SPEED CAL number will appear. Exit
“CAL” by pressing “CAL” for one second.

The speed sen sor is now calibrated. To verify proper
calibration, repeat the procedure a sec ond time. Write
down the new speed calibration number and keep it in a
safe place. If the cal i bra tion values are ever accidentally
changed, you can simply re-en ter this num ber.

Appendix C - Fine Tuning Flowmeter Calibration Value

(If system is set up for NH3 application, see page 57)

This procedure is used to verify and fine-tune the flowmeter
calibration. Every flowmeter is calibrated with water at the
factory and stamped with a calibration val ue. Enter that
value as a starting point and use this pro ce dure to fine­tune that value for your specific in stal la tion and spray ing
application. This procedure should be re peat ed each time a
new solution is being applied (differ ing so lu tions will have a
different spe cif ic gravities and different flow char ac ter is tics)
or when the flowmeter in stal la tion has been altered.

PROCEDURE

1. Put enough water in the sprayer tank to perform this
test. (Preferably 100 gallons or more. The larg er the
volume of water used, the more accurate will be the
calibration.)

2. Start sprayer pump and turn on booms. Run enough
water to purge all air from lines. Turn off booms but
leave pump running.

3. Turn console rotary selector to the VOLUME po si tion.
Select the counter (1-3) that you want to use. Press and
hold the RESET button until the dis play reads 0 (about 2
seconds).

4. Turn on all booms, turn Run/Hold switch to RUN, and
run a known amount of water (preferably 100 gallons or
more).

*

5. Put Run/Hold switch in HOLD position. Compare the
console’s VOLUME reading with the known amount of
water run. If the two amounts are within one or two
per cent, no fine tuning is required. If the two amounts
are more than two or three percent dif fer ent, con tin ue
with the next step.

6. With the console still in the VOLUME position, enter
calibration, hold the CAL button until red warning light
comes on; about one second). The dis play will show the
flowmeter calibration value and the CAL icon.

7. Momentarily press the CAL button. The CAL icon will
begin to flash and the total volume will be displayed.

See Illustration to the right.

8. When the TOTAL FLOW value is displayed, use the “+”
or
“-” button to adjust the value to match the amount of
water run.

9. Momentarily press the CAL button. The CAL icon and
the flowmeter calibration number will be displayed.
You will notice that the flowmeter calibration value has
changed. Write down the new flowmeter calibration
value. This is your “fine tuned” calibration value, keep it
for future reference.

10. Exit calibration by holding the “CAL” button until the
red warning light goes out (about one second).

The most accurate method to measure the volume

*

of water run is to place a container under EVERY
nozzle and add together the amount from each
nozzle. This assures that 100 percent of the water is
collected and that all nozzles are spraying equally.
It is important to perform this pro ce dure at a flow
rate similar to that which will be used in the field.
It is also possible to disconnect the main boom line
and run it to a large measuring container but a valve
must be installed and properly adjusted to simulate
actual field conditions.

Appendix D - Flowmeter Assembly

IMPORTANT: Opening the flowmeter will void the
Flowmeter Calibration value assigned to your unit.
However, you may need to take the flowmeter apart for
periodic cleaning or to remove an obstruction.

If you can shake the flowmeter from end-to-end to produce
a “rattling” sound (shaft-end play), or if you can blow into
the meter from either end and cause the turbine to spin
freely, your flowmeter DOES NOT need cleaning. If you
CANNOT hear the “rattling” sound or get the turbine to spin
freely, your flowmeter needs to be cleaned. See Illustrations

below for reassembly instructions.

OPENING THE FLOWMETER

Cut the calibration tag retaining wire. Remove the screws
and disassemble the flowmeter. Do not attempt to remove
the sleeve bearings from the flowmeter housing.

Use warm water and if necessary, a mild detergent and a
soft bristle brush to clean all parts. Do not use solvents or
diesel fuel to clean the flowmeter. A magnet works well for
removing fine metallic particles from the turbine.

Inspect all parts. Check for excessive bearing or shaft wear.
The shaft will wear shorter until the turbine drags on the
housing. Illustration 17 shows you what a new shaft looks
like. When the shaft is worn to the point of drag, the turbine
must be replaced.

On a flat surface, place each housing half on end. Set and
spin the turbine in each half. It should spin freely. If it does
not spin freely, remove the turbine, wipe the shaft and try
again. If is still does not spin freely, the shaft or bearings
may have excessive wear. (Service may be necessary.)

ASSEMBLING THE FLOWMETER

Stainless steel meters use a Teflon gasket. Sealants are
normally not required. Plastic meters use an o-ring (Quad­ring). Apply a small amount of silicon grease for lubrication.
Gaskets and o-rings may be reused several times but
eventually may need replacement.

Place the turbine in the non-sensor housing. Position
gasket /o-ring; carefully place sensor housing over turbine.
Drop all screws into holes. Hold nuts (and lock washers on
stainless meters) in place and finger-tighten screws. Ensure
proper placement of gasket/o-ring and evenly tighten all
screws. Attach tag.

After assembly, shaking flowmeter end-to-end should
produce a “rattling” sound (shaft end play). Blowing into
the meter from either end should cause the turbine to spin
freely. If the turbine only spins from one direction, install
the flowmeter so that the liquid flows in that direction
(service may be required).

For maximum accuracy the flowmeter should be mounted
in a vertical position. Re-calibration is required before field
operation.

MT-3405FTM II NH3 Kit Installation

PRE-INSTALLATION

Remove the NH3 Kit plumbing panel from the shipping
board. Before installing the unit on your applicator, make
sure all brackets rest on a flat surface. If necessary, loosen
carriage bolts (two per bracket) at base of brackets to allow
all brackets to rest flat on mounting surface of tool bar.
Tighten carriage bolts only after insuring that all brackets
rest on bar and unit does not rock on center bracket.

INSTALLATION:

Remove any existing metering valves. If the old metering
valve has a built-in manifold, it is recommended to install a
separate new manifold for the Liquifier™ kit. Another option,
although not recommended, is to use the existing manifold,
making certain the old metering valve is in the maximum
open position to allow for minimal restriction of flow through
the plumbing. There should not be any positive shut-off
valves installed in the plumbing between the Liquifier™ kit
shut-off valve and the knives.

Install the plumbing panel on the tool bar frame using the
carriage bolts and flange lock nuts through the top and
bottom brackets of the system. Trim any excess length off
the bolts if required. Attach the hose from the breakaway
coupler to the strainer inlet. Check for proper hose length
for operation of the disconnect mechanism of the breakaway
coupler. Connect the manifold hose to the servo valve outlet.
Check for proper hose length to avoid kinking at the hinge
points.

INSTALLATION NOTE: It is recommended to use an NH3
compatible thread sealing compound such on all pipe
thread fittings

IMPORTANT!

Vapor tube plumbing MUST be connected to the
Liquifier™ vapor outlets for the system to work
correctly. Operating the Liquifier™ without the vapor
tubes will present serious health and safety hazards.

Locate the ½” EVA vapor hose supplied with the kit. Starting
on one half of the tool bar, connect the ½” hose to the
outside steel vapor tube. Route the hose up the shank
and along the tool bar frame to the inside steel vapor
tube. Allow enough extra hose to avoid kinking at hinge
points. Cut the hose to length and attach to the inside steel
vapor tube. Install a ½” x ¾” x ½” tee fitting approximately
halfway along this hose between the outside and inside
steel vapor tubes. See Illustration below. Repeat the same
procedure for the steel vapor tubes on the other half of the
tool bar. Secure all hoses with properly sized hose clamps.
Secure the hoses to the tool bar frame with cable ties.

Locate the ¾” EVA hose supplied with the kit. Connect to
one of the ½” x ¾” x ½” tee fittings and route along the tool
bar frame to the vapor outlet connections on the Liquifier™.
Repeat for other half of tool bar. Allow enough extra hose
to avoid kinking at hinge points. Secure all hoses with
properly sized hose clamps. Secure the hoses to the tool
bar frame with cable ties.

FOR ALL NH3 KITS

Weld the steel vapor
tubes to the back of
your liquid tubes. All
electronic equipment,
including the console
and radar speed
sensor, MUST BE

DISCONNECTED
BEFORE WELDING
ON EQUIPMENT. The

four steel vapor tubes
should be evenly

Fine Tuning Speed/Distance Calibration Val ue - NH3 Systems

This procedure is used to verify the speed/distance
calibration. In order to achieve accurate measurements,
each step in this fine tuning procedure should be
performed as precisely as possible.

CAUTION: Do not perform this procedure with the nurse
tank connected to the system.

PREPARATION

• Once the system is fully installed and calibrated, se lect
a straight tract of ground that is similar to your ac tu al
field conditions and as level as pos si ble.

NOTE: Us ing a course with a different ground sur-

face, such as a hard-surface road, will re sult in dif fer­ent read ings than exact field con di tions.

• Measure a distance of 1000 feet (500 meters).
Clear ly mark the beginning and end points with
flags or some thing highly visible to the operator.

PROCEDURE

1. With the console turned ON, place the Run/Hold switch

in the HOLD position. The HOLD icon will be displayed.
Turn the rotary dial to the “DISTANCE” position. Be sure
the display shows 0. If not, reset the distance counter
by pressing and holding “RESET” until the display
returns to 0 (approximately one second). The word
CLEAr will be displayed when reset is pressed.

2. You are now ready to drive the measured course. Pick

a location on the vehicle to use as a marker for starting
and stopping the distance counting function (door
handle, mirror, step, etc.). You should begin driving the
course well ahead of the starting flag and drive past the
ending flag, using the Run/Hold switch to start and stop
the counting function. It is not recommended to start
from a dead stop at the starting flag and stop at the
ending flag.

3. Place the Run/Hold switch in RUN when the marker

on the vehicle passes the starting flag to activate
the distance counting function. The console display
numbers will increase, adding to the distance total as
you drive. Drive the pre-measured course and place
the Run/Hold switch in HOLD, when the marker on the
vehicle passes the ending flag, to stop the distance
counting function. The console display should read
“HOLD”. See Illustration. Stop the vehicle in a level
and safe area and continue with this procedure.

4. With the rotary dial still at DISTANCE (SPEED CAL), press
and hold the “CAL” key for one second. Once the con­sole is in “CAL,” CAL and the speed calibration value
will be displayed. Momentarily press CAL and the word
CAL will begin to flash and the distance travelled will be
displayed.

5. When the display shows distance (“CAL” is flashing),
ver i fy wheth er the number displayed is the ex act dis­tance you drove (with in +/- 1 - 2 %). If not, press the
“+” or “-” key to ad just the fig ure to match the dis tance
you ac tu al ly drove. If the display reads too high, use the
“-” key to lower the dis played value. If the display reads
too low, use the “+” key to raise the displayed value.

6. When the number shown on the display match es (as
close ly as possible) the ac tu al dis tance driv en, you
have ar rived at the cor rect cal i bra tion val ue. If you
can not adjust the displayed distance to exactly match
the actual dis tance driven, adjust the figure as close
as possible to the actual distance. You may check the
calibration number by momentarily pressing CAL. The
word CAL and the SPEED CAL number will appear. Exit
“CAL” by pressing “CAL” for one second.

The speed sen sor is now calibrated. To verify proper
calibration, repeat the procedure a sec ond time. Write
down the new speed calibration number and keep it in a
safe place. If the cal i bra tion values are ever accidentally
changed, you can simply re-en ter this num ber.

Fine Tuning Flow Calibration Val ue - NH3 Systems

This procedure is used to verify and fine-tune the
flowmeter calibration. Every flowmeter is calibrated with
water at the factory and stamped with a calibration val ue.
Enter that value as a starting point and use this pro ce­dure to fine-tune that value for your specific in stal la tion
and NH3 application (please refer to En ter ing Flow me ter

Calibration Value, page 25).

PROCEDURE

1. Start with a full nurse tank. Make certain that you have
an accurate scaled weight of the full tank. You will
want to apply a minimum of 1,000 pounds of NH3 for
this procedure. The larger the volume of NH3 used, the
more accurate the calibration will be.

2. With the Run/Hold switch in HOLD, turn the rotary
selector to the VOLUME (1) (2) (3) position. Select
which pair of VOLUME/AREA counters (1, 2, or 3) that
you want to use by using the “+” button ONLY to
select the pair of counters as identified by the small
number in the lower right area of the left-hand display.
If you attempt to use the “-” button, it will clear the
selected counter pair (CLEAr will be displayed before
the counters are cleared). After you have selected the
counter pair number, press and hold the RESET button
until the display reads 0.0.

3. Proceed to the field and perform actual application
(turn Boom 1 on, RUN/HOLD switch to RUN) until at
least 1,000 pounds of NH3 has been applied. (One
nurse tank is preferred). The larger the volume of NH3
applied, the more accurate the calibration will be.
Obtain an accurate scaled weight of the partially used
nurse tank. The difference between the starting and
ending weight is your calibration weight.

7. When the TOTAL FLOW value is displayed, use the “+”
or
“-” button to adjust the value to match the amount of
NH3 run.

8. Momentarily press the CAL button. The CAL icon and
the flowmeter calibration number will be displayed.
You will notice that the flowmeter calibration value has
changed. Write down the new flowmeter calibration
value. This is your “fine tuned” calibration value, keep it
for future reference.

9. Exit calibration by holding the “CAL” button until the
red warning light goes out (about one second).

Appendix E (cont)

Field Operation - Troubleshooting for NH3

Always follow accepted safety precautions. Make sure that
equipment is in good operating order. Before connecting
the nurse tank to the applicator, check the electric shut-off
valve of the MT-3405F™ II system for proper operation.

After changing nurse tanks or after other periods of long
shut-down, operate the system in MAN until the application
rate stabilizes. This allows the heat exchanger to reach
operating temperature before selecting AUTO. Erratic
operation may be experienced if AUTO is selected before
operating temperature is reached.

Manifold pressure is very important for good distribution
of NH3. Use barbed fittings with properly sized orifices or
an adjustable manifold to maintain adequate pressure. If
manifold back pressure is too low, proper cooling will not
be achieved, vapor bubbles will be allowed to enter the
flowmeter, and readings will be inaccurate. Typical manifold
pressure ranges from 15 to 60 PSI (1 to 4 bar) depending
on application rates and ambient temperature. If manifold
pressure stops climbing but FLOW RATE continues to climb,
vapor bubbles are present.

Additional Troubleshooting Tips for NH3

See Troubleshooting section, starting on page 33.

In hilly or rough conditions the nurse tank dip tube will not
remain submerged, allowing extra vapor in the system. This
vapor is to too much for the heat exchanger to condense
and the system will exhibit erratic operation. If the dip tube
remains out of liquid, operation may appear to be normal,
but the system is simply metering vapor. If this occurs,
you will notice extremely low manifold pressure. Change
tanks before the NH3 level is low enough to cause these
problems.

In NH3 control systems, location of the frost build-up is an
indication of system performance. The NH3 kit will normally
have frost on the output side of the servo valve and in some
cases, a small amount on the bottom portion of the heat
exchanger. Frost before the servo valve indicates excessive
pressure drop in the delivery system or restricted vapor
lines.

The strainer is a common source of excessive pressure drop
and should be cleaned regularly. AFTER COMPLETELY
DRAINING THE SYSTEM, remove the large plug and
carefully clean the strainer’s screen. Also, periodically check
the vapor tubes for obstructions.

MT-3405FTM II NH3 Specific Flowmeter Assembly (FM-750 N)

IMPORTANT: Opening the flowmeter will void the Flow
Calibration value assigned to your unit. However, you may
need to take the flowmeter apart for periodic cleaning or to
remove an obstruction. See illustration below for flowmeter

reassembly instructions.

TO OPEN THE FLOWMETER

Disconnect the hose from servo valve to manifold. Loosen
the union hex closest to the heat exchanger. Remove the
two “U” bolts that hold the servo/flowmeter assembly to the
brackets. Unscrew the union from the heat exchanger and
remove the servo/flowmeter assembly.

Use running water to rinse the assembly of any
accumulated dirt. Remove the three flowmeter bolts,
carefully open the flowmeter and remove the turbine.
Thoroughly clean turbine and housings of any foreign
material (dirt, pieces of teflon tape, rust on magnets, etc.).

Set and spin the turbine in each flowmeter housing half. It
should spin freely. If not, remove the turbine, wipe the shaft
and try again.

TO ASSEMBLE THE FLOWMETER

Place the servo, flowmeter end up, in a vice or other suitable
fixture. Set turbine in non-sensor housing. Properly position
gasket on housing. (Gasket may be reused a few times but
will eventually need to be replaced.) Pipe thread compound
is not absolutely necessary but will insure a good seal. Be
careful not to get compound inside flowmeter or turbine
will stall. Carefully put other flowmeter housing (sensor half)
in place. (Position the housing so that the two square lugs
are lined up with each other.) Drop all three bolts into holes.
Hold lock washers in place and finger tighten all three nuts.
Nuts should be torqued to 120 in./lb. (13.56 nw/m). Attach
tag by running wire between a bolt and the housings, and
twisting.

After assembly, shaking flowmeter end-to-end should
produce a “rattling” sound (shaft end play). Blowing into
the meter from either end should cause the turbine to spin
freely. If the turbine only spins from one direction, install
the flowmeter so that the liquid flows in that direction.

Start with original calibration number and follow procedure
in manual for verifying flowmeter accuracy.

WARNING!!

TO PREVENT SERIOUS INJURY, DO THE FOLLOWING:

1. ALWAYS WEAR gloves, goggles, and other necessary

equipment when handling NH3 apparatus.

2. DO NOT cross thread. Use anti-seize lead base thread
compound.

3. THOROUGHLY BLEED hoses before disconnecting NH3
apparatus.

4. COMPLETELY EVACUATE NH3 apparatus before servicing.

Appendix G - Using the MT-3405 II with VRA

The MT-3405F ™ II has a 9-pin serial connector on the
back panel which allows it to be connected to any “GPS /
Mapping Controller”.

A GPS/Mapping system typically consists of special
hardware that runs on a laptop/PDA, or dedicated mapping
controller. The MT-3405F™ II may be connected to any
such device that supports Micro-Trak products.

This allows for the following mapping activities:

“AS APPLIED” MAPPING

In this case the GPS/Mapping Controller just collects data.
In either MAN or AUTO operating modes, the console
simply reports its current application rate.

VARIABLE RATE APPLICATION

In order to accept VRA commands, the console must be
operating in ‘AUTO’.

While in ‘AUTO’, the GPS/Mapping computer is in control of
the application rate, and consequently the console’s adjust
rate buttons (+ and -) are disabled.

When outside of the prescribed mapping area, the GPS/
MAPPING computer puts the MT-3405F™ II in “Hold” (stops
spraying) by simply sending a target rate of zero.

MANUAL OVERRIDE OF VRA

There may be times when the operator needs to
apply more or less that the prescribed rate. In such
a case, pressing ‘MAN’ allows the operator to make
adjustments using the + and - buttons. To resume the
prescribed rate, simply exit the manual override by
pressing the AUTO button.

NOTE: While in MAN override, the console will not
miss any new rate commands sent by the GPS/
Mapping Controller. They are simply ignored until
the user toggles back to AUTO, at which point the
most recent prescribed rate is resumed.

VRA Testing Procedures:

CABLE CONNECTION

Use a standard pin-for-pin (not “null-modem”) serial
communications cable to connect the Micro-Trak console to
the GPS/Mapping controller. One end of the cable should
be a DB9 male and the other end a DB9 female.

NOTE: Only 3 wires are used (Tx, Rx and Gnd: Pins 2, 3 & 5).

COMMUNICATIONS SETTINGS

The Micro-Trak console uses the following serial settings:

9600 baud, 8,N,1 (8 data bits, no parity, 1 stop bit).

NOTE: These numbers are in the software NOT the Micro­Trak Console.

FUNCTIONALITY TEST

You can verify the connection and functionality by using
the standard “HyperTerminal” communications program,
which can be found on any computer running MS-Windows.

Connect a computer (PC, laptop) to the Micro-Trak console,
and configure HyperTerminal (‘Port Settings’ tab) as follows:

• Select a known working COM port on your computer

• Select the communication settings as listed above:

IMPORTANT: ‘Flow Control’ must be set to none.

The following tests assume the Micro-Trak console is power
up, and ‘AUTO’ is selected (DOES NOT require speed or flow
signal).

1. Put console into HOLD, by sending a target rate of zero.

Type the following, a signal character at a time: S,0,
(capital S; comma; then ZERO and a trailing comma).

The console goes into HOLD immediately after the last
comma.

2. Send a new target rate.

Send a target rate of 12.3 by typing: S,123,

Once the trailing comma is sent, the console
immediately changes to the new target rate of 12.3.

3. Verify the new rate

Retrieve current rate status by typing one character: R

The console immediately responds with a ‘D’ followed
by a number of comma-separated fields (datalist):

• The 1st data field (D,123,) is the current target rate [12.3].

• The 2nd data field (D,123,###, is the actual rate.

Appendix I - Motorized Hydraulic Flow Control Valve

How do I select the correct control valve?

To select the valve best suited for your application, you
need to know the maximum hydraulic oil flow rate; the
following information may be helpful:

1. Hydraulic Motor Displacement

Determine the motor displacement required for your
application. Motor displacement is the amount of oil
moved per revolution of the motor (typically rated in
cubic inches). This specification will be determined
by the torque and rpm requirements of the delivery
system. Your motor supplier will be the best resource
for matching a suitable motor with your application
needs. (If the motor rating is given in cubic centimeters
simply multiply cubic centimeters by .061 to convert it
to cubic inches.)

2. Maximum Hydraulic Oil Flow

Calculate the maximum oil requirements for your
application. Simply multiply the maximum motor
rpm by the motor displacement. For example,
the maximum oil flow for a 300 rpm motor with a
displacement of 4.8 is 1440 (300 x 4.8 = 1440).

3. Maximum Gallons per Minute of Oil Flow

Calculate the maximum gallons per minute (GPM)
of oil flow required for your application. There are
231 cubic inches of hydraulic oil per gallon so simply
divide the maximum oil flow by 231 and multiply by
.8 (control valve rating factor). For this example, the
maximum GPM of oil flow is 4.99 (1440 ÷ 231 x .8 =

4.99). The control valve best suited for this example is
the 5 GPM valve (rated just higher than maximum GPM
requirement of 4.99).

Bigger isn’t always better. Selecting the 10 GPM valve
(or larger) would result in roughly half of the control
range of the valve being unused. For optimum system

performance, select the control valve with the rating
closest to the maximum GPM requirements of your
application. Continue reading for valve options and
specifications.

DESCRIPTION

The Motorized Hydraulic Flow Control Valve is a two
wire polarity reversing valve. Change polarity to open
or close the valve, cut 12VDC power to hold valve at
desired setting. All that is required for basic control is
a double-pole double-throw switch. It also works great
with Micro-Trak’s full line of automatic rate controllers.

Appendix J - Secondary Boom Control

For liquid material there is an optional “Dual Boom” feature
that allows a secondary boom line (SBE) to be turned On/Off
by using either the Flow or Speed as a trip point.

Please note that this feature uses the “Relief Output” (see
page 22). In other words you must choose between either a
Relief or SBE output - but NOT both at the same time.

As an example, the MT-3405 front panel switches control
the sections on the primary boom, which works for the
normal operating range of the nozzles. However, there
may be instances where extra flow is needed (greater than
the output capacity of the nozzles on the primary boom) ­in which case a secondary boom line can be turned on to
meet the extended target application rate.

ENABLING THE ‘DUAL BOOM’ FEATURE

In order to enable this feature and set up the trip points,
turn the rotary knob to the ‘WIDTH’ position, enter
Calibration mode, and make sure the console switch is set
to HOLD.

The currently selected control units, Speed or Flow, will be
displayed

Select either FLOW or SPEED control of the secondary boom
by pressing the CAL key to toggle the right-hand display
between ‘FLO’ (flow-based control) and ‘SPEEd’ (speed­based control).

FLOW

If in Flow control, FLO will display in the Application Rate
(right) display and the trip-point value will be displayed in
Gallons per Minute, (or Liters per Minute) in the Data (left)
display. If the flow (VOLUME/MINUTE) ever exceeds this trip
point setting, then the Secondary Boom Enable output goes
high, turning on the Secondary boom. When the flow drops
below the trip point the Secondary boom will turn off.

NOTE: Typically you want the secondary boom to
turn on when the primary boom reaches a certain
pressure. To determine the trip point value, consult
the manufacturers nozzle charts and do the following
calculation, if the chart indicates that your nozzle
output is 0.2 gpm at 40 psi, then take the total
number of nozzles on your system and multiply
that by the specified gpm value. In our example,
the system has 36 nozzles, so we enter a value
of 7.2 (36 * 0.2 gpm = 7.2 gpm) for the FLOW trip
point. Assuming all nozzles are in good working
condition (no clogs, worn, etc.), the secondary boom
will automatically turn on when the total pressure
reaches 40 psi.

CALHOLD

SETTING THE ‘TRIP’ POINTS

When the desired control mode is displayed, use the +
and - (RESET) keys to adjust the value. Entering a value
will automatically clear the value for the alternate control
setting. For example if Flow was selected with trip-point
value of 7.2 GPM, entering a value of 10.0MPH for Speed will
enable Speed control and disable Flow control (‘OFF’).

CALHOLD

SPEED

If in Speed control, SPEEd will display in the Rate display
and miles per hour (or kilometers per hour) will be
displayed in the Data display. If the Speed ever exceeds this
trip point setting, then the Secondary Boom Enable output
goes high. When the speed drops below the trip point, the
Secondary boom will turn off.

* NOTE: The SBE (Secondary Boom Enable) output always
turns off when in HOLD.

DISABLING THE ‘DUAL BOOM’ FEATURE

To disable Dual Boom control, you must enter ‘.00’ for
both trip points (default setting from the factory). Be sure
to press the CAL button a few times (right display toggles
between ‘FLO’ or ‘SPEED’) to verify that each is set to zero
(left display shows “OFF”).
