Electrical Installation
Universal Switch Harness
This section explains how to hook-up your MT-2405 FTW
(with existing switches) to a 12-volt power connection, and
how to connect your boom shut-off valves.
NOTE: If you are using a Micro-Trak Switch Box,please see
Micro-Trak Switch Box Harness instructions on page 12.
The MT-2405 FTW 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
Figure 1.5. Connect the RED wire to the contact point you
have located. Attach the BLACK wire (ground) to a screw or
boltonthe equipment frame.Seeinsetbelow.(A4-amp inline
fuse is recommended 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-2405 FTW is equipped with an electronic 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 Trak-Star speed sensor,
disregard the section on magnetic speed sensors and install
theTrak-Star as described in the instructions packed with the
unit.
Speed Sensor Installation
Locate the following parts:
Speed sensor cable
Mounting“L”bracket
Magnet clips
Magnets
CableTies
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.
Magnets
Pleasereadthefollowinginformationaboutmagnetspacing
and polarity.
The number of magnets that must be used depends on
where you mount the sensor.The general rule for tractor or
implement wheels is one magnet for each wheel bolt
(minimumof two,andalwaysuse anevennumber).Fordrive
shafts or small wheels (ATV’s), two magnets are usually
adequate.
The magnets provided by Micro-Trak are marked with a
dashed line on the SOUTHpole side of the magnet. See
Figure1.11.
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 Figure1.12.
For proper operation, the magnets must be evenly spaced
around the wheel or drive shaft. The magnets must be at
least 1" apart.SeeFigure1.13.
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 (meters). Divide that
measurement by 20 for English and Turf units, or by .5 for
metric units,and then round up to the nearest even number
(always use an even number of magnets). That number will
be the minimum number of magnets required for
installation,to allow speeds as low as 0.5 mph.
Example in English/Turf units: If your revolution
measurement is 97 inches,dividing that number by 20 gives
you a value of 4.85. Rounding 4.85 up to the nearest even
1" minimum

Rounding 5 up to the nearest even number is 6. For this
example,the minimum number of magnets required is 6.

Refer to the following diagram for general mounting
instructions. For specific mounting instructions, refer to
Appendix A in the back of this manual.
NOTE: Magnets may be attached mechanically as shown or
adhered with epoxy or other high quality adhesive. When
using adhesive,thoroughly clean the area of dirt and oil.

Attaching Magnets
The magnets are attached to a wheel hub or drive shaft
and the speed sensor is mounted directly over the magnet.
When the wheel or drive shaft begins turning, a speed
impulse is sent to the MT-2405 FTW console every time a
magnet passes by the tip of the speed sensor.For the speed
sensor to operate properly, the spacing between the
magnets and the tip of the sensor must always remain
constant. Before permanently mounting any parts, be sure
that the location you have selected will meet the following
requirements –SeeFigure1.14.

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
onthemainharness.Thespeedsensorandtheflowsensorare
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
Figure1.15.
Installation Note: The main harness provides two
connection points for the speed sensor. For speed sensor

Mounting and Plumbing Flowmeter
The flowmeter must be installed in the boom supply line
after any strainers, return lines, or valves,but before the
boom shut-off valves. Securely mount flowmeter
(hardware not supplied) in a vertical position in an area
away from intense vibration. Do not install flowmeter
closer than 12" to the servo valve or the boom shut-off
valves. (The flowmeter may need periodic cleaning,so it
should be easy to remove.) The flow meter is a bi-
directional meter (exception: Polmac’s 1 1/2"–3"). Liquid
can flow in either direction, but up is preferred. Make
connections using appropriate fittings without the use
of reducers, elbows or sharp bends for a minimum
of six inches (15 cm) either side of meter. See
Figure1.16.
Save plastic plugs to protect flowmeter during
storage.

With the flowmeter in place, install the flow sensor cable
(GREEN body).
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.SeeFigure1.17.
Note: Sensors with GREEN bodies can be used for either SPEED
orFLOWbut notfor RUN/HOLD.

Pressure ReliefValve
If you have a positive displacement pump or a centrifugal
pumpcapable ofgeneratingexcessivepressure,you mustin-
stall a pressure relief valve and adjust it to a safe maximum
pressure. If a positive displacement pump is operated
without a pressure relief valve,damage may result to pump
or other plumbing component.SeeFigure1.18. Pressure

Servo,ThrottlingValves
The servo valve installs in an unrestricted return line to the
inlet of the pump or directly into the tank.DO NOT install the
servo valve closer than 12" to the flowmeter.The servo valve
has a flow direction decal on it.Make certain that the actual
flow direction matches the decal on the servo valve.Do not
install the servo valve in the agitation line. Slow response
time and marginal operation may result. The return line
should tee from the main line just after the throttling valve.
SeeFigure1.19.Thethrottling valveis usedto limitthe output
(set maximum output) of the pump to the flowmeter and
servo valve.The throttling valve is adjusted to put the servo
valve in its optimal operating range.Please refer to Pre-Field
System Checkout for proper valve adjustment procedure.
The servo valve connects directly to the main harness 3-pin
W/P cable lead. If more length is required, use a 3-pin W/P
extensioncableoftheappropriatelength.IfusingaBragliaor
other 12-volt control valve, please refer to 12-Volt Control
Valve Calibration,Appendix E.

NOTE: The servo valve may be installed in the main spray
line. For in-line installations, you will need to cut the servo
cable and reverse the wires. Connect the RED wire to the
BLACK wire and vice versa. Failure to reverse the wires will
result in the servo valve operating backwards.
Electric Relief Valve
An electric relief valve minimizes pressure build-up by
opening a “by-pass dump”line when all boom valves are
closed. An electric relief valve is not a replacement for a
mechanical relief valve.If your pump can produce pressures
above the limits of your plumbing (positive displacement
pumps),a mechanical relief valve is required.
Whenever all the boom control switches are turned off, or
when HOLD is selected, the electric relief valve should be
open. Use this plumbing figure (See Figure 1.20) as your
pattern for proper installation of your relief valve. DO NOT
install the relief valve closer than 12" to the flowmeter.With
the relief valve installed, locate each solenoid cable and
crimp an insulated quick disconnect (Q.D.) terminal on each
wire. Connect the wires on the terminals to the relief valve
connect the 2-pin M/P connector to the relief lead on the
main harness (no tie). Be careful not to connect the relief
valvecabletooneoftheboomshut-offleads.Alloftheboom
shut-off leads have a colored tie near the 2-pin M/P
connector.The relief solenoid lead does not.

If your sprayer is equipped with an electric relief solenoid
valve, follow these instructions to ensure proper installation
and operation.
With the addition of the optional Relay Kit, if at least one
boom is ON, the relief valve will be closed. If all booms are
OFF, the relay will open the relief valve, providing bypass of
the spraying solution.

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.
The run/hold sensor has a BLACK body. DO NOT use a
speed/flow sensor (GREEN body).SeeFigure1.22.
•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 (side with dashed line)
of the magnet. Check the polarity of the magnet by
bringing it near the run/hold sensor with the console
turnedon. Note andmark thefaceofthemagnet thatis
toward the sensor when the console does not indicate
“HOLD.”When the magnet is away from the sensor,the
console will be in HOLD and will shut off the boom
valves and stop counting acres.NOTE:The run/hold kit
includesa5' sensor cableand10' extension.You mayre-
quire 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.
