Introduction to the FlowTrak II
The FlowTrak II sprayer Monitor, like the original FlowTrak, provides a complete picture of critical spraying functions and is easy to
install and operate. The system monitors and displays:
NEW FEATURES in the FlowTrak II include additional
Volume and Area counters and a new “Tank” feature.
The console can also be programmed to operate either as a
sprayer monitor, or as a batch counter for filling tanks:
SPRAYER MONITOR MODE: When used in typical
spraying operations, the “Control output” should be
programmed to the “HOLd” mode; the Control output can
turn an external valve or pump ON/OFF in response to the
status of the Run/Hold button or the optional remote Run/
Hold sensor, and the Tank counter will show the amount
remaining in the tank. When operating in this mode, the
Tank alarm feature can also be used; it will flash “FILL” on the
display when the tank reaches a (settable) low level. See the
calibration and operation sections for details.

BATCH MODE: When used in a batching operation or at a
depot where tanks would be filled, the “Control output” can
be programmed in the “FILL” mode. In this mode the Control
output will control a valve or pump used to fill the tank,
turning the valve or pump OFF when the amount reaches a
(settable) level. In this mode, the TANK display will show the
amount that has been pumped into the tank and the tank
alarm is inoperative. This mode requires a fill flowmeter and
possibly a relay adapter if high current levels are required.

Electrical Installation
This section explains how to connect your FlowTrak II to a
12-volt power source.
NOTE: The FlowTrak II must be connected to a 12-volt DC
negative ground electrical system.
Route the power cable of the FlowTrak II harness from the
console to the switched source, plug the connector into the
mating plug for the console and connect the red wire to the
switched power source as shown in Illustration 3 (terminal

or wire). Connect the black wire to a screw or bolt on the
equipment frame. Use your test light to locate a terminal or
wire connected to your ignition switch which is “hot” when
the ig ni tion is turned on and “dead” when the ignition is off.
Your FlowTrak 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.

Speed Sensor Installation
Please Note: If you have purchased an Astro GPS Speed
Sensor or a Vansco radar speed sensor, disregard the
following section on magnetic speed sensors and install
the speed sensor as described in the instructions included
with the unit. You may need an adapter cable to connect
to some radars, see Appendix C.
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.
Locate the following parts:
• Speed sensor cable (Green body) • Magnets
• Mounting “L” bracket • Cable ties
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)

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.
Illustration 6
The magnets provided by Micro-Trak are marked with a
punched dashed line on the SOUTH pole side of the magnet.
See Illustration 4.
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 5.
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 6.

Attaching the Speed Sensor
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 FlowTrak 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 5.
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 FlowTrak II Wiring
Diagram on page 8.
The optional Run/hold sensor 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 FlowTrak II Wiring
Diagram on page 8.

Speed Sensor Options
In addition to the standard Hall-effect magnetic speed
sensor, the FlowTrak II may be interfaced with a va ri ety 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.
Radar Interface
The FlowTrak II may also be interfaced with most popular
radar ground speed sensors. An adapter cable is re quired for
proper interface.
SEE APPENDIX C FOR LIST OF ADAPTER CABLES FOR RADAR.
Vansco Radar
Speed Sensor
GPS Speed Sensor Interface
The FlowTrak 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 de tails on
any of these products, or call Mi cro-Trak Systems, Inc. at

Installation (cont)
Mounting and Plumbing Flowmeter
The Flowmeter must be installed in the main boom line
after any strainers or return lines. Se cure ly mount flow me ter
(hardware not supplied) in a vertical position in an area away
from in tense vibration. DO NOT install flowmeter closer than
12” to servo valve or boom shut-off valves. The flowmeter 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 con nec tions us ing appropriate
fit tings without the use of reducers, elbows or sharp bends
for a minimum of six inches (15 cm) either side of meter. See Illustration 6. Save plastic plugs to protect flowmeter during
storage. (The flow me ter 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 3-pin connector on the main harness marked with a
GREEN cable tie. Screw sensor all the way into hole of flowme ter. Tighten 3/8” jam nut to secure sen sor in place.

IMPORTANT:
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 im ple ment
is raised and lowered. The Hall-effect Run/Hold sensor is
sensitive only to the south pole of the magnet. Install
the magnet with the dashed line facing the sensor.
When the mag net is away from the sen sor, the con sole
will be in HOLD and the area and distance counting
functions will be disabled. NOTE: The run/hold kit
includes a 5’ sensor cable and 10’ extension. You may
re quire additional extension cables which are avail able
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. Sim ply
cut the black 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.

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 imum 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 8.
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. See Illustration 9.

See the following table for SPEED CAL numbers to enter for
various radar models or GPS speed sensors. To fine tune the
Determining the Speed Cal (Skip this section if using radar or GPS speed sensor)
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 12. 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 page 22.
Drive Shaft Speed Sensor Calibration
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.
To determine SPEED CAL, measure the distance of one
complete wheel revolution and divide by the number of
magnets installed.
Illustration 12
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 next
section.

Calibration (cont)
Fine Tuning Speed/Distance Calibration Val ue
PREPARATION:
In order to achieve accurate measurements, each step in this
fine tuning procedure should be performed as precisely as
possible.
1. 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.
2. 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.
NOTE: Us ing a course with a different ground sur face, such
as a hard surface road, will re sult in dif fer ent read ings than
actual field con di tions.
Procedure
1. With the console turned ON, use the Run/Hold button
to select HOLD mode. 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.
5. When the display shows distance (“CAL” is flashing), veri fy wheth er the number displayed is the ex act dis tance
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 tual 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.
NOTE: 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.
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 button 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. Use the Run/Hold button to select RUN mode 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
use the Run/Hold button to select HOLD mode, 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
con sole 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 traveled will be
displayed. See Illustration.

Calibration (cont)
Fine Tuning Flowmeter Calibration Value
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 fine-tune 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 different specif 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, and run a known amount of water
(preferably 100 gallons or more).
5. Turn off all booms. Compare the console’s VOLUME
reading with the known amount of water run. See Illustration. 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 and in
HOLD, enter calibration (boom switches OFF, 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.
*
8. When the TOTAL VOLUME 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 word CAL 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.

Operation in the Batch(tank Fill) Mode
To operate in the Tank FILL mode, select the FILL control
mode, see Special Calibration.
Make sure your system is properly calibrated before beginning
to monitor your application.
CONSOLE POWER/SYSTEM ON/OFF: The system can be
turned ON and OFF by the ignition switch. When the console
is turned on, it will display the number of hours of operation
for 2 seconds, then it will display the software version along
with the “v” icon for 2 seconds before it begins normal
operation.
DISPLAY: During Tank FILL operations, the console will
display either the tank level as it is filled (TANK position), or
the flow rate (VOLUME/MINUTE) as selected by the rotary

Resetting System Counters
Not Applicable to the Batch (tank Fill) Mode
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. Counters may be reset independently of
each other.
1. 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.

Troubleshooting (cont)
General
All FlowTrak II consoles and flowmeters 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.
Problems can be 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).
SPEED IS ALWAYS ZERO OR ERRATIC
Check for properly calibrated speed cal number.
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 Halleffect sensors and console inputs on pages 34-35.
DISTANCE COUNT IS INACCURATE
Speed cal number was incorrectly calculated or entered.
Review calibration, re-adjust and test.
AREA COUNT IS INACCURATE
Working width or wheel circumference was measured
incorrectly, or speed cal number was calculated or entered
incorrectly. Go back through the original procedures, make
changes, and test for acre (hectare) count again. Verify
accuracy with formula:
Acres = Distance x Width in feet/43560
Hectares = Distance x Width in meters/10,000
Thousands of square feet = Distance x Width in feet/1000
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.
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
material may be lodged in the flowmeter.
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 on page 24.
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 FlowTrak II cables away from the radio,
its antenna and power cable.
Ignition wires may be causing the console to malfunction.
Keep FlowTrak II cables away from ignition wires, or install
ignition suppressor.
Reroute all cable away from electric solenoids, air conditioning
clutches and similar equipment.
DISPLAYED MEASUREMENTS DO NOT MAKE SENSE
The console may be in the incorrect measurement mode
(English or metric). See page 18 for instructions.
DISPLAY READS “OFL”
DISTANCE, AREA, and VOLUME counters read OFL when
they have exceeded their maximum count. Reset to zero to
resume counting.

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 8.
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 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
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”.
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 (face with
dotted line) 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 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.
RUN/HOLD JUMPER DUST COVER
To test for proper continuity on the jumper wire, connect the
ohmmeter to the pins of the dust cover with the jumper wire.
There should be continuity — near zero ohms.
8. If the system passes all above tests, the radar may be
defective.
32
Troubleshooting (cont)
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 con nec 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 14). The console should respond
with some speed read ing.
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 (white) and C (black) 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 (red) and C (black) of the 3-pin connector. The con sole
should re spond with some flow rate reading.
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 43 for details.
PLUMBING
Proper plumbing is a very important factor in obtaining
optimal performance from your FlowTrak 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 flowmeter is installed correctly
and is 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 36-38.

REMOTE RUN/HOLD INPUT
Disconnect the remote run/hold sensor (or jumper cover)
from the main harness.
Check for 12 volts between pins B (green) and C (violet) of
the main harness remote run/hold cable (grey tie). Placing a
clip lead or other jumper wire (such as a paper clip bent in a
“U”) between pins A (blue) and C (violet) of the main harness
run/hold connector (grey tie) should turn off the “HOLD”

Plumbing Guidelines
General
In order for your sprayer to function properly, it must be
correctly plumbed. 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 into four sections and cover each
one separately. The four 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 shut-off
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.
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.
PUMP
The pump must have enough capacity to satisfy the agitation,
servo and flowmeter sections of the plumbing. 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’ boom with 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 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.
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). Now slowly
screw handle in until maximum desired pressure is reached.
Lock handle in place with locking nut or collar.
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. If the throttle valve needs to be
more than two thirds closed, open the Range valve slightly.
THROTTLE VALVE
The throttle valve limits your high end to maximize servo
performance. Start with throttle valve fully open.
Example: With the throttle fully open, you may be able to
get 50 GPA at 5 MPH when you only want 25 GPA.
Therefore, close the throttle until your high end

difficult to adjust and keep adjusted. Do not

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 fine tuning procedure,
see pages 19-20.
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 dashed line on the SOUTH pole side of the
magnet.

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. 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. Recalibration is required before field
operation.
