Universal Switch Harness
This section explains how to hook-up your MT-2405FTW II
(with existing switches) to a 12-volt power connection, and
how to connect your boom shut-off valves.
The MT-2405FTW II must be connected to a 12-volt DC
negative ground electrical system. Using your test light,
locate a terminal or wire connected to your ignition switch
which is “hot” when the ignition is turned on and “dead”
when the ignition is off.
Locate the power cable on the main wiring harness. See
Illustration 3. Connect the RED wire to the contact point you
have located. Attach the BLACK wire (ground) to a screw
NOTE: For Negative Ground Systems ONLY.

or bolt on the equipment frame. See inset below. (A 4-amp
in-line fuse is required for unprotected circuits.) Be sure there
is a good metal-to-metal contact. The terminal connectors
have been supplied for your convenience. You may wish to
substitute other types of connectors or make a direct solder
connection. In routing cable to console, avoid areas where
the cable may be subjected to abrasion or excessive heat.
Your MT-2405FTW II is equipped with a non-volatile memory
which does not require a constant supply of power to
retain daily totals or calibration values. This type of memory
conserves battery power and will not discharge the vehicle’s
battery when equipment is not in use.

PLEASE NOTE: If you have purchased a Vansco or other
radar or GPS speed sensor, disregard the section on
magnetic speed sensors and install the radar or GPS Speed
Sensor as described in the instructions packed with the
unit. You will need an adapter cable to connect to radar or
GPS Speed Sensor, see Appendix H.
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 B for installation details.
Magnets
Please read the following information about magnet spacing
and polarity.
The number of magnets that must be used depends on
the size of your tire and where you mount the sensor. On
tractor or implement wheels the general rule of thumb is one
magnet for each wheel bolt (minimum of two, and always an
even number). For drive shafts or small wheels (ATV’s), two
magnets are usually adequate.
Some installations may require that more than two magnets
be installed. To determine the number of magnets required,
measure the distance traveled of one revolution of the
sensor equipped wheel in inches (centimeters).
See the following tables to find the minimum number of
magnets required (always an even number) -
The magnets provided by Micro-Trak are marked with a
punched dashed line on the SOUTH pole side of the magnet.
See Illustration 6A.
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 6B.
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 6C.
NOTE: Magnets may be attached mechanically or adhered
with epoxy or other high quality adhesive. When using
adhesive, thoroughly clean the area of dirt and oil.

The magnets are attached to a wheel hub or drive shaft and
the speed sensor is mounted directly over the magnet. When
the wheel or drive shaft begins turning, a speed impulse
is sent to the MT-2405FTW 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 7.
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 main harness cable having a YELLOW cable tie near
the 3-pin M/P connector. Make certain that you install the
correct sensor cable and connect it to the correct connector
on the main harness. The speed sensor and the flow sensor
are identical, but must be connected to the proper harness
connector. The speed sensor always connects to the main
harness lead with the YELLOW tie and flow sensor always
connects to the main harness lead with the GREEN tie. See
MT-2405FTW II Wiring Diagram on page 9.
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. See MT-2405FTW II Wiring Diagram on page 9.

Speed Sensor Options
In addition to the standard Hall-effect magnetic speed
sensor, the MT-2405F II may be interfaced with a variety of
other speed sensing equipment. Several options are listed
below.
Astro GPS Speed Sensor
The Astro is an easy-to-install economical alternate to radar
speed sensors. The Astro is available with either a 1 HZ or 5
HZ GPS receiver. The sensor converts GPS signals to a pulsed
speed signal, providing an accurate speed input even in
conditions where radar does not perform well.
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.
Astro GPS Speed Sensor
Radar Interface
The MT-2405F II may also be interfaced with most popular
radar ground speed sensors. An adapter cable is required for
proper interface.
SEE APPENDIX I FOR LIST OF ADAPTER CABLES FOR RADAR.
GPS Speed Sensor Interface
The MT-2405F II may also be used with most other GPS
speed sensors that output a pulsed signal, such as SkyTrak
or Dickey-John GPS speed sensors. An adapter cable may
be required.
Contact a Micro-Trak dealer/distributor for details on any of these products,
or call Micro-Trak Systems, Inc. at 1-800-328-9613.

The Flowmeter must be installed in the main boom line after
any strainers, return lines, or valves. Securely mount flowme-
ter (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 is a bidirectional meter (exception: Polmac’s
1 1/2”—3”). Liquid can flow in either direction, but up is
preferred, especially at rates below 5 GPM (19 lpm). 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 8. Save plastic plugs to
protect flowmeter during storage. (The flowmeter may need
periodic cleaning, so it should be easy to remove.)
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 main harness cable, having a GREEN cable tie near
the 3-pin M/P connector. 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 9.
NOTE: Sensors with GREEN bodies can be used for either
SPEED or FLOW but not for RUN/HOLD.
Connect flow sensor cable to green-tie console cable.

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 10.
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 11. 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 25-26 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-2405FTW II with an old
-style Micro-Trak servo valve, the valve voltage must be set
to 8 volts.
NOTE: The servo valve may be installed in the main spray
line as shown in Illustration 12. For in-line installations, you
will need to calibrate the system for INLINE operation, see
page 20.

Remote Run/Hold
The run/hold sensor cable has a BLACK body and a GRAY tie
near the 3-pin M/P connector and mates with the main har-
ness cable having a GRAY cable tie near the 3-pin M/P con-
nector. Make certain that you install the correct sensor cable
and connect it to the correct connector on the main harness.
See Illustration 13. If not using Run/Hold cable for remote
use, make certain a dust cover with jumper is installed.
• The basic idea is to attach a magnet to a lever or some
part of the equipment that moves when the implement
is raised and lowered. The Hall-effect Run/Hold sensor
is sensitive only to the south pole of the magnet. Check
the polarity of the magnet by bringing it near the Run/
Hold sensor with the console turned on. Note and mark
the face of the magnet that is toward the sensor when
the console does not indicate “HOLD.” Install the magnet
with the marked side facing the sensor. When the mag-
net is away from the sensor, the console will be in HOLD
and the area and distance counting functions will be
disabled. The solenoid valves will also shut off if the
optional relay kit has been installed. NOTE: The run/hold
kit includes a 5’ sensor cable and 10’ extension. You may
require additional extension cables which are available
in 5 ft. (1.5 m), 10 ft. (3 m), 15 ft. (4.5 m), 20 ft. (6 m) and
25 ft. (7.6 m) lengths.
• You may also use a toggle or other type switch. Simply
cut the blue jumper wire in the dust cover and splice on
an appropriate length of wire to reach your switch. Do
not connect to a switch with power.
When switch is closed, console is in RUN. When the switch is
open, the console is in HOLD.

The MT-2405FTW II is capable of displaying information in
American English or standard Metric measurement. The
MT-2405FTW II is shipped from the factory programmed for
English. NOTE: The following procedures will also load
factory default calibration values. To simply change units
without loading defaults, see the “Special Calibration”
section.
METRIC
• You must be in HOLD or have all booms OFF to enter Cal.
To activate the Metric mode, turn power OFF and place
the rotary switch at “AREA.” Hold down both the “CAL”
and “-” keys and turn power ON. See Illustration 14. The
console will display LOAd for two seconds. Once LOAd is
displayed, release the two keys. To “lock-in” Metric mode
you must enter and exit calibration. Press and hold the CAL
key until “CAL” icon appears on the display. The console is
now in calibration and Metric mode is selected. Exit CAL by
pressing and holding the “CAL” key until CAL disappears
from the display (approximately 1 second). NOTE: You
must exit CAL to lock in Metric units.
ENGLISH
• You must be in HOLD or have all booms OFF to enter
Cal. To activate the English mode, turn power OFF and
place the rotary switch in the VOLUME position. Hold
down both the “CAL” and “-” keys and turn power ON.
The console will display LOAd. Once LOAd is displayed,
release the two keys. To “lock-in” English mode you must
enter and exit calibration. Press and hold the CAL key until
“CAL” lights on the display. The console is now in calibra-
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 recommended to
attempt calibration while the vehicle is moving.) The console
will remain in calibration mode, with the RED warning light
illuminated until you exit calibration or turn power OFF.
Once in calibration mode, you may change any one, all, or
none of the values, in any order.* To select a calibration
position, simply turn the rotary selector to the desired
position. Calibration positions are identified by the WHITE
labeling on each side of the rotary selector. All values are
entered and adjusted using the “+” and “-” buttons on the
front panel.
*Test speed must be last.
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.

ADJUST RATE: Enter the value for the desired amount
of change in gallons per acre (liters per hectare) to be
used for making on-the-go rate adjustments
when operating in AUTO. For example, if a
value “1.0” is entered,
you will be able to
increase or decrease
your application rate in
one-gallon (liter) increments during operation in AUTO. To
disable this feature, simply enter “.0” for a value.
INLINE/BYPASS: The display will show InLinE or bYPASS.
Use the “+” or “-” buttons to toggle to desired selection. Inline
is used when the servo is in the line going out
to the booms; Bypass is used when the servo
is in a return line.
CAUTION: If spray lines
are pressurized, nozzles
may spray during this
step below.
WIDTH: Enter the effective working width, in inches (meters)
for the boom section currently shown on the display. It is
simplest to start with
all booms ON and
then turn each boom
OFF, from left to right,
after calibrating the width. Note that the
system must be in RUN (not HOLD) to display
boom numbers. If the display is flashing “no”
“boonn” either all the booms are OFF or the
system is in HOLD. Enter a value of “0” (.000)
for any unused boom section switches.
Your “working” width per boom section will be the number
of nozzles on the boom section times the nozzle spacing
in inches (mm). For example, if you have 7 nozzles spaced
at 20 inches, the working width of the boom section is 140
inches.

MIN FLOW: The purpose of this calibration value is to
prevent the system from applying below the recommended
minimum rate for the
nozzles. The minimum
flow rate in gallons
per minute (liters per
minute) based on the nozzles being used,
for the entire boom on the sprayer. DO NOT
enter the actual flow of your spray application. For example:
If the minimum flow rate for the nozzle you are using is .22
GPM at their minimum recommended pressure and your
boom has 20 nozzles, enter 4.4 as the MIN FLOW value (.22
x 20 = 4.4). The system WILL NOT apply at a rate lower than
this value when spraying in AUTO. This value should be
checked/ changed for each different nozzle that you use.
APPLICATION NOTE: Over-application may occur with
MIN FLOW set if ground speed is too slow.
