Installation

Mounting the Display Console & Switches

Select a mounting location that is convenient to reach
and highly visible to the operator. DO NOT INSTALL IN
A POSITION THAT OBSTRUCTS THE VIEW OF THE ROAD
OR WORK AREA. Whenever possible, avoid locations that
expose the console to direct sunlight, high temperature,
strong chemicals or rain.

Place the mounting bracket in the selected location, mark
holes, drill 1/4” (7mm) holes and mount bracket with bolts,
lock washers and nuts provided. (Use self-tapping screws if
not practical to use bolts.) See Illustration 1.

Put rubber washers on carriage bolts and put the bolts
through the bracket holes from the inside out. Place
console over carriage b olt heads.

Install the switch brackets over the carriage bolts and
alongside the console bracket. Install the mount knobs on
the carriage bolts and tighten to secure the console and
switch brackets in place. See Illustrations 2 & 3.

Install the switches in the brackets, making sure that the
“ON” position is oriented up. Attach the quick disconnects
on the switch harnesses to the switches (see wiring
diagram). Then install the switch harness connectors into
the mating connectors on the console harness. Typically
the power On/Off switch (Kit 14360) is mounted on the left
and the Run/Hold switch (Kit 14361) is mounted on the
right.

Speed Sensor Installation

Installation Note: The harness provides local connection
for the speed sensor. For speed sensor installations on
implements, add 3-pin extension cables as required.

Please Note: If you have purchased an Astro GPS Speed
Sensor, a Vansco radar or other radar or GPS speed sensor,
install the Astro, the Vansco or other radar as described in
the instructions included with the unit. You may need an
adapter cable to connect to radar or GPS Speed Sensor, see
Appendix F.

NOTE: If using a Micro-Trak Magnetic Speed Sensor kit, See
Appendix A.

Astro 5 GPS Speed Sensor

SPEED SENSOR OPTIONS

In addition to the standard Hall-effect magnetic speed
sensor, the RoadMasteR™ 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 RoadMasteR™ may also be used with most GPS speed
sensors that output a pulsed signal, such as the Micro-Trak
Astro 5, SkyTrak or Dickey-John GPS speed sensors. An
adapter cable may be required.

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 RoadMasteR™ may also be interfaced with most popular
radar ground speed sensors. An adapter cable is re quired for
proper interface.

SEE APPENDIX F FOR LIST OF ADAPTER CABLES FOR RADAR.

Vansco Radar
Speed Sensor

Mounting and Plumbing Flowmeter

The owmeter must be installed in the main line after
any strainers, return lines, or valves. Securely mount
owmeter in an area away from intense vibration. A
vertical installation with ow entering the bottom
is preferred, especially at rates below 5 gallons per
minute. Other orientations are sucient providing
the owmeter remains full of uid. To avoid erratic
ow readings allow a minimum of 6” of straight tub­ing at the owmeter input and output. If installation
constraints don’t allow this keep bends as gentle as
possible. Micro-Trak ow meters are bidirectional (ex­ception: green plastic turbine and mag owmeters are
one direction only). Flipping the owmeter periodically
(black nylon and stainless steel Micro-Trak manufac­tured models) to reverse the ow will greatly extend
the life of the owmeter by evening out bearing wear.

Typical Installation

Last, route the flow sensor cable to meet the extension
cable from the main harness flow connector marked with
FLOW label. Align connectors and press firmly together
until locking tab clicks into place. Secure cable with ties
provided.

NOTE: Sensors with GREEN bodies can be used for either
SPEED or FLOW.

Installing Servo Valve

On most installations, the servo valve installs in the main
unrestricted spray line, between the flowmeter and the lane
shut-off valves. It is not recommended to 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.

The servo valve connects directly to the main harness 3-pin
W/P cable lead. If more length is required, use a 3-pin W/P
extension cable of the appropriate length.

Installing a Tank Empty Switch

A connection (See Wiring Diagram on Page 8) is provided
for a “Tank Empty” switch. (Not available from Micro-Trak)
The switch must be a 2-wire, closed when tank is NOT
empty and open when tank IS empty. Remove jumper and
add 3-pin extension cables as required to reach the switch.

NOTE: Your RoadMasteR™ flowmeter has been tested at the
factory and assigned a “FLOW CAL” value to make it operate
properly with the RoadMaster™ console. This number is
printed on the white plastic tag attached to the flowmeter.
See Illustration 7. In the illustration example, the liquid
calibration number is “148”. This is a starting point only. If
your spray solution has a specific gravity or viscosity that is
different than water, flowmeter calibration should be done
for the specific solution (please refer to Fine-Tuning Flow­me ter Calibration in Appendix D on page 36.)

MIN FLOW: The pur pose of this calibration setting is to

prevent the system from applying below the recommended
minimum ow rate for the nozzles. Enter the minimum
ow rate in gallons

of the applicator. DO NOT enter the target
ow of your spray application. For example: If the min i mum
ow rate for the nozzle you are using is .22 GPM at their
minimum recommended pres sure and your section has 20
nozzles, enter 4.4 as the MIN FLOW value (.22 x 20 = 4.4). The

Your “working” width per section will be the number of

inches, the working width of the section is 140 inches.

NOTE: RoadMasteR™ consoles are equipped with 3 Section
switches. In Lane Mode the CENTER Section switch is
always the PRIMARY Section and is used to define the
“LANE WIDTH”. Ag, Dust or Turf Modes can use any
Section switch. If the operator is only using ONE Section
it must be the Primary Section.

CAUTION: If spray lines are pressurized, nozzles may spray
during WIDTH calibration (below).

NOTE: When in Lane Mode, a Lane Mile/kilometer
is defined as the area in a swath equal to the Center
(Primary) Section width, that is one (1) mile/km long.
The user defines a Lane Mile/kilometer by changing the
Center Section width. For example, if the Center (Primary)
Section Width is set to 12 feet, and the Left and Right

AUTO

1

The RoadMasteR™ system can be operated in either Manual
or Automatic mode. In manual mode, the application rates
(See table below for different rates) are set using the “+”
and “-” buttons; the application rate will vary depending on
the vehicle speed. The manual mode is useful for system
set up, spot applications, etc.

To turn on the AUTO mode, press AUTO/MAN button so
the AUTO icon appears in upper right portion of display. In
automatic mode, the system will maintain the calibrated
application rate when the vehicle speed changes, or
sections are turned on or off. To operate the system in
automatic mode, simply turn on the desired number of
sections, place the RUN/HOLD switch in the RUN position
and drive. NOTE: In AUTO mode, the system will not turn
the sections on until it has a speed signal. Use the Section
switches, the RUN/HOLD switch or remote RUN/HOLD
sensor to Start or Stop application at any time. See the
following sections for operation details.

CONSOLE POWER/SYSTEM ON/OFF

When the RoadMasteR™ Console is turned on , except when
starting SPECIAL CALIBRATE, the data display will show the
Number of Hours it has operated for one (1) second, the
Software Part Number (45022) and Software Revision for

1.5 seconds each. Then it will display Std for 1.5 seconds
showing that this is a Standard DC Servo Drive Console.

DISPLAY

During normal operation, the console will display
information selected by the rotary switch position. Typically
the rotary switch will be set on RATE, as shown in Illustration

BLAST BUTTON

The BLAST function is intended for spot applications
(bridge decks, intersections) at a higher rate. The BLAST
calibration functions include BLAST TARGET RATE and
BLAST DURATION. When the user presses the BLAST switch
in Auto, the system will display BLASt and output the preset
rate for a preset period. The period starts after the BLAST
switch is released. If the BLAST switch is pressed again
during the reset period, BLAST will be cancelled. When the
BLAST is complete, the system returns to normal operations.
BLAST will NOT function in Manual mode or if the system is
in HOLD or stopped.

“+” AND “” BUTTONS

During normal operation, when automatic “AUTO” control
mode is active and the rotary dial is set to RATE, each press
of the “+” or “-” buttons will increase or decrease the target
application rate by the amount of the calibrated Adjust
Rate.

RUN/HOLD SWITCH

The RUN/HOLD is the master switch for turning all
(active) sections on and off. This function can be done
either manually with the included RUN/HOLD switch, or
automatically, using the optional RUN/HOLD sensor kit.

AUTO/MAN BUTTON

This button will switch the control status of the system from
fully automatic to manual control. Each press of the button
will change the status. The display will show the AUTO icon
when automatic control mode is active and the MAN icon
when manual control mode is active. NOTE: IF IN “AUTO”

MODE AND NO SPEED SIGNAL IS PRESENT, SYSTEM WILL
SHUT OFF THE SECTIONS AUTOMATICALLY.

During normal operation, when manual “MAN” control
mode is active and the Run/Hold switch is in the RUN
position, and Rotary dial is set to RATE or VOLUME/MINUTE,
pressing the “+” or “-” buttons will increase or decrease the
application rate.

During normal operation, when either automatic or
manual mode is active, the RUN/HOLD switch is in the
HOLD position and the rotary switch is turned to VOLUME/
MINUTE, pressing the “+” or “-” button will increase or
decrease the flow rate without having the section valves
turned on. This can be useful for system pressure checking.

Operation (cont.)

Console Switches & Buttons (cont.)

SECTION SWITCHES

The system monitors the status of the section switches
to determine whether they are ON or OFF. The console
accumulates area based on the calibrated section widths.
When an individual section is turned OFF, the respective
width is subtracted from the total width to accumulate area
based on the new active application width. If the rotary
switch is in the RATE position, the numbers 1, 2, or 3 on the
display will light when their respective section is ON.

NOTE: Most RoadMasteR™ consoles are equipped with
3 Section switches. In Lane Mode the CENTER Section
switch is always the PRIMARY Section and is used to
define the “LANE WIDTH”. Ag, Dust or Turf Modes can
use any Section switch. If the operator is only using ONE
Section it must be the Primary Section.

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.

NOTE: VOLUME, AREA, DISTANCE & SPEED counters
work in sets, if the VOLUME counter 1 is reset, it also
resets AREA counter 1, DISTANCE counter 1 and SPEED
counter 1. This will be the same for resetting any
counters in the set. Do Not use the “-” button to select
counters because the button will clear them. (See
Resetting System Counters on page 25). The active set of
counters may be reset to zero independent of other sets
of system counters.

SERIAL PORT

The DB-9 connector on the back of the console provides
access for serial communication. The serial configuration
is RS-232, 9600 baud, in 8-N-1 half-duplex format. Data is
sent and received in comma-delimited ASCII format. An
external device (GPS/Mapping/AVL System) can change the
application rate on-the-go and also receives and records
data from the RoadMasteR™. See Appendix H and I for data

lists available.

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:

1. The Tank Level is below minimum level (TANK ALARM

SET POINT).

2. Float switch is continuously active for 15 seconds or

more.

3. 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 Sections 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

Pre-Application Sys tem Checkout

Before beginning actual application, perform the following
“Pre-field” procedure to ensure that your valve settings,
nozzle selection and desired speed range will allow the
RoadMasteR™ to provide the required application control.
By performing all of the steps listed below, you set up your
system to allow the RoadMasteR™ to perform at optimum
level. Fill your application tank with clean water. DO NOT
use chemicals until the entire sys tem is completely checked
out and operating properly.

NOTE: Pre-field System Checkout is a procedure
performed while the console is in the CAL mode. During
the procedure and “CAL” on the display will be flashing.

Troubleshooting (cont.)

General

All RoadMasteR™ consoles, flowmeters and harnesses 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, DO NOT OPEN THE CONSOLE.
Your system is protected by a warranty, and Micro-Trak
Systems, Inc. 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. Trace cable toward battery look ing for breaks.
Also check any fuses or circuit break ers that supply
pow er to the console. Then 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. If using a Magnetic
Speed Sensor, 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.

NOTE: For more suggestions on solutions to speed
problems, see console input section and Troubleshooting
SPEED Sensor section on next page.

AREA COUNT IS INACCURATE

• Implement width or Speed Calibration was measured
incorrectly or programmed incorrectly. Go back through
the original procedures, make changes, and test for area

count again. Verify accuracy with formula:

Turf = Distance x Width in feet/1000
Yard2 = Distance x Width in yards
Acres = Distance x Width in feet/43560
Hectares = Distance x Width in meters/10,000
Meters2 = Distance x Width in meters

DISTANCE COUNT IS INACCURATE

• Speed Calibration was incorrectly measured or entered.
Review calibration, readjust and test. See Appendix C.

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

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

• Check to see that a FLOW CAL number has been
entered. Also check cable for breaks or incomplete con­nection. (See Console Input Section). If the owmeter
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 owmeter. 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. See Flow me ter

Assembly; Appendix E, for details.

TOTAL LIQUID USED IS INACCURATE

• This may result from an incorrectly-entered “FLOW CAL”
value. Check the number stamped on the owmeter
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.

• Check the mounting position of the owmeter. With
lower ow rates, the meter should be mounted verti­cally with ow going up.

• Another cause may be inaccurate sprayer tank mark­ings.

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 and/or spark plugs.

DISPLAYED MEASUREMENTS DO NOT MAKE SENSE

• The console may be in the incorrect measurement units
(English or Metric) or Application mode.

NOTE: Changing UNITS will load defaults, so they should
always be changed first and then all other CALIBRATE
and SPECIAL CALIBRATE values may be set.

• MODE SELECT in CALIBRATE allows the user to change
the MODE. Pressing the “+” or “-” (Reset) will toggle be­tween Lane, Ag, Dust and Turf (except in Metric) MODE
and the display will show LAnE, Ag, dUSt and turF.

DISPLAY READS “99999”

• DISTANCE, TOTAL AREA, and TOTAL FLOW will read
99999 when they have reached their maximum count.
Reset to zero to reset counter.

Troubleshooting (cont)

Checking Individual Components

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 nec­tor. 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 (red) and C (yellow) 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 (orange) and C
(yellow) of the 3-pin connector (See Illustration 11). The
console should respond with some speed read ing.

FLOW INPUT

Turn rotary switch to VOLUME/MINUTE (not RATE) and
disconnect the flow sen sor (green tie) from the main
harness. Check for 12 volts be tween pins A (violet) and B
(gray) 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 B (gray)
and C (blue) of the 3-pin connector (See Il lus tra tion 11).
The con sole should re spond with some Volume/Minute
reading.

TANK SWITCH INPUT

First Verify that ALARM ENABLE is ON. (See “Special”
Calibration page 21). With ALARM ENABLE turned ON, if

the Tank Switch is opened, the Audible Alarm should turn
on after a 15 second delay. If the switch is closed, the
alarm will turn off. Verify by disconnecting the switch and
shorting pins A and C on the cable connector.

RUN/HOLD INPUT

If using P/N 14361 (Run/Hold Switch Kit) or other switch,
disconnect the cable from the switch and the HOLD Icon
will NOT be displayed. Short between pins A and C and
the HOLD Icon should turn on; if not, the console input is
bad, otherwise either the switch or extension cable is bad.
If using a Hall-Effect magnet Run/Hold sensor, first check
for 12V between B and C, then proceed per above.

Illustration 11

HARNESS

The harness can be checked using an ohm me ter or
continuity tester. The main wiring diagram shows the pin­out of all connectors. See page 8 for wiring diagram.

MAGNETIC HALL-EFFECT SPEED AND FLOW SENSORS

Caution: Improper connection or voltage could damage the
Hall-effect sensor. This par tic ular type of Hall-effect sen sor
re quires al ter nat 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.

SPEED SENSOR

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.

FLOW SENSOR

• Ground pin B and connect clean 12 volts to pin A of
the ow sensor cable. Con nect the positive lead (red)
of an ohmmeter or con ti nu ity tester to pin C (red) and
the negative lead (black) of the ohmmeter or continuity
tester to pin B of the ow 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  nite),
while holding the tip of the sensor up to the south pole
of a magnet should result in a very low resistance (near
zero).

ASTRO II AND ASTRO 5 GPS

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

1. Check that 12 VDC power is available to the sensor. The

LED closest to the connector cable indicates power on.
(The other LED indicates GPS signal acquired)

2. Test the console inputs as described on this page.

3. Check to make sure that the GPS module is

securely mounted.

4. Check for any damage to the 10 foot receiver cable.

5. If system still does not function, the Astro may be

defective.

VANSCO RADAR SPEED SENSOR

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

1. Check that 12 VDC power is available to the sensor.

2. Test the console inputs as described on this page.

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

Plumbing Guidelines

GENERAL

In order for your sprayer to function properly, it must be
correctly plumbed.

Avoid pressure drops wherever possible. All hoses, valves
and fittings (especially elbows) can cause undesirable
pressure losses.
Follow these guidelines:

• Keep hoses as large as practical

• Don’t use longer hoses than necessary

• Avoid bends when 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
drops for various fittings and hose sizes.

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 basics; leaky fittings and hoses, pinched
hoses, and plugged or worn nozzles can affect performance.

PUMP INLET

The hose connecting the tank to the pump should be at
least as large as the pump inlet port. 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, the system may not be able to reach the
intended application rate and pump damage could occur.

FLOWMETER

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

PUMP

The pump must have enough capacity to achieve desired
application rate. To determine if your pump is large enough,
you must add up the volume per minute of all active
sections.

Appendices

Appendix A

Optional Speed Sensor Mounting Installation

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
wheels the general rule of thumb is one magnet for each
wheel bolt (minimum of two, and always an even number).
For drive shafts, 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

12A.

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 12B.

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 12C.

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.

Locations where the magnetic sensor may be installed:

1. Non-driven wheel on the vehicle. This is less susceptible
to errors resulting from wheel slip.

2. Vehicle 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 non­driven wheel. See Appendix B for magnetic speed
sensor installation details for various types of wheels or
drive shaft.

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 RoadMasteR™ 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 13.

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
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 the RoadMaster™ Wiring Diagram on page 8.

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 16.

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

Sensor Body

(Green)

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, lock washers 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
tie as close to sensor assembly as possible.

Drive Shaft Speed Sensor Calibration

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 (10-15) and then fine-tune the
cal i bra tion.

Go to Appendix C for Fine-Tuning Instructions.

34

Appendix B

Calibrating if Using a Magnetic Speed Sensor

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 14. 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 C on
page 36.

Illustration 14

To determine SPEED CAL, measure the distance

of one complete wheel revolution and divide

by the number of magnets installed.

35

Appendix C

Fine Tuning Speed/Distance

Calibration Val ue

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
application 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 fer ent read­ings than exact application conditions.

• Measure an appropriate distance for Application Mode.
AG and TURF are measured in feet (meters). Dust is
measured in yards (meters) and Lane is measured in
miles (km). 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.
Select the Counter (1 - 3) you want to use. Be sure the
display shows 0. If not, reset the distance counter by
pressing and holding “RESET” until the display returns to
0 (approximately two seconds). The word CLEAr will be
displayed when reset is pressed. Make sure pump is o.
Turn on Section switches.

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 ag and drive past the
ending ag, 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 ag and stop at the

ending ag.

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

the vehicle passes the starting ag 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 ag, to stop the distance counting function.
The console display should display “HOLD”. 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 “BLAST” key for one second. Once the
con sole is in “CAL,” the speed calibration value will be
displayed. Momentarily press BLAST and the word CAL
will begin to ash and the distance travelled will be

displayed. See Illustration 15.

5. When the display shows distance (“CAL” is ashing), ver-

i 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 g 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 gure as close as possible to
the actual distance. You may check the calibration num­ber by momentarily pressing BLAST. The word CAL will
stop ashing and the SPEED CAL number will appear.

Exit “CAL” by pressing “BLAST” 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

Fine Tuning Flowmeter

Calibration Val ue

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.

This procedure is used to verify and fine-tune the flowmeter
calibration. This procedure should be repeated periodically,
i.e. the beginning of each season.

PROCEDURE

1. Put enough water in the tank to perform this test,

preferably 100 gallons or more. The larger the volume of
water used, the more accurate the calibration.

2. Set up a container to collect the liquid running through

the system. The most accurate method to measure the
volume of water run is to disconnect a main section
line and run it into a large container. You can also place
a container under EVERY nozzle and add together the
amount from each nozzle. It is important to perform
this procedure at a ow rate similar to that which will be

used in the eld.

3. Start pump.

4. Turn on at least one section.

5. Put the controller in MANUAL mode. You may need

to press the + or – buttons to adjust the ow of liquid
through the system. Adjust the system pressure to the
target pressure or adjust the ow rate to the target ow

rate.

6. Run enough water to purge all air from lines.

7. Turn o all sections but leave pump running.

8. Turn console rotary knob to the VOLUME position.

9. Press and hold the RESET button until the display reads

0 (1 second).

10. Turn on at least one section and run a known amount

a water through the system (preferably 100 gallons or
more).

11. Stop the ow by putting the Run/Hold switch in the

HOLD position or by turning o all sections. Compare
the console’s VOLUME reading with the amount of water

collected.

12. With the console in the VOLUME position, enter calibra-

tion mode. The display will show the current owmeter
calibration value and the CAL icon.

13. Momentarily press the BLAST button, The CAL icon

will begin to ash and the total volume counter will be
displayed.

14. Use the “+” or “-” button to adjust the value to match the

actual amount of water collected.

15. Momentarily press the BLAST button. The CAL icon

stops ashing and a new owmeter calibration number
will be displayed. This is your “ne tuned” calibration

number, keep it for future reference.

16. Exit calibration by holding the BLAST 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 line and run it to a large measuring container but a
valve must be installed and properly adjusted to simulate
actual field conditions.

Flowmeter Cleaning

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.

The example flowmeter shown for this procedure is a Micro­Trak FM270. These steps will also work for the Micro-Trak
FM10/100 flowmeter. For information about any other
model, please contact Micro-Trak directly.

DISASSEMBLING THE FM270 FLOWMETER

1. Remove the Retaining Ring on one end of the flowme-

ter by compressing tabs together and pulling it out.

2. Carefully remove the Bearing Housing by grasping one

of the internal support fins with a needle-nose pliers
and pulling. Rotating the Housing slightly while pulling
may help slide it out. Avoid contacting the turbine with
any tools.

3. Remove the turbine and set it aside. Do NOT remove the

Spacer inside the center area of the flowmeter.

4. Repeat Steps 1-3 for the other end of the flowmeter.

CLEANING THE FM270 FLOWMETER PARTS

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 Bearing Housing 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).
Rebuild kits are available from Micro-Trak.

REASSEMBLING THE FLOWMETER

Simply reverse the disassembly procedure to reassemble
the flowmeter.

After assembly, shaking the 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.
