SPEED SENSOR OPTIONS
In addition to the standard Hall-effect magnetic speed
sensor, the RoadMasteR™ may be interfaced with a variety of
other speed sensing equipment. Several options are listed
below.
ASTROSERIESOROTHERGPSSPEEDSENSORINTERFACES
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 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 tub-
ing 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 (ex-
ception: green plastic turbine and mag owmeters are
one direction only). Flipping the owmeter periodically
(black nylon and stainless steel Micro-Trak manufac-
tured models) to reverse the ow will greatly extend
the life of the owmeter by evening out bearing wear.
Mounting and Plumbing Flowmeter

Installing External BLAST Switch
An optional external Momentary On BLAST switch can be
connected to the two quick-connect terminals provided on
the harness (See Wiring Diagram on Page 8). The remote
BLAST switch allows the operator to control the BLAST
function from a switch mounted on an armrest or other
convenient location. An optional switch box that includes
the BLAST switch and RUN/HOLD switch is available from
Micro-Trak Systems, Inc.
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.

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.

DEFINITIONS OF LANE, AG, DUST AND TURF MODES:
LANE: Used for Highway Maintenance Applications
where Area is accumulated in Units of Lane Miles (Lane
Km). Distance is in Units of Miles (Km) and Application
Rate is in amount of liquid per Lane Mile (Lane Km).
AGRICULTURAL: Mainly used for roadside spraying,
where Area is in acres (hectares), Distance is in feet
(meters) and Application Rates are in Gallons/Acre (liters/
meter2).
DUST CONTROL: Used for controlling suspended
particulates, where Area is in square yards (square
meters), Distance is in yards (meters) and Application
Rates are in Gallons/Yard2(liters/meter2.
TURF (English Only): Where Area is in 1000 square
feet, Distance is in feet and Application Rates are in
Gallons/1000 feet2.
NOTE: A Mode change CLEARS the counters if
Calibration is exited correctly. If power to the console
is turned off before exiting Calibration, the counters
are NOT cleared.
MODE SELECT: MODE SELECT 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.

SELECT
CALIBRATION SEQUENCE
Once in calibration mode, you may change any one, all, or
none of the values, in any order, but it is very important
to set MODE first. Mode Select defines the unit of
measurement for all system calculations.
Note: TEST SPEED is NOT a calibration setting. It simulates
vehicle speed during Pre-Application System Checkout.
This procedure is described on page 26.
TARGET RATE: Selecting TARGET RATE (in English) displays
the desired application rate in these units:
LANE mode - Gallons per Lane Mile
AG mode - Gallons per Acre
DUST mode - Gallons
per Sq. Yard
TURF mode - Gal-
lons per 1000 Sq. Feet
Selecting TARGET RATE (in Metric) displays the desired appli-
cation rate in Liters/Lane Km for LANE mode, Liters/Hectare
for AG Mode and Liters/Meters2for DUST mode. TURF mode
does not apply to Metric settings. This is the application
rate that the console will lock onto when operating in AUTO.
The Warning LED will ash and Audible Alarm will sound if
enabled whenever the actual application rate is more than
10% from TARGET RATE.
TARGET
RATE RATE

WIDTH CAL: Displays the Section WIDTH in inches for the
Section selected (Unused Section must be set to zero). The
total width (sum of all Section widths) must not exceed
65,535 inches or 65.535
meters. To adjust a
particular section, turn
that Section switch on
and all others OFF. If no
Sections are turned on it will display
“NO BOOM” to remind the user to turn a
section on.
Note: The system must be in RUN to
display section numbers. Repeat this procedure for each
section. Enter a value of "0" (.000) for any unused sections.
Your “working” width per section will be the number of
nozzles on the section times the nozzle spacing in inches
(meters). For example, if you have 7 nozzles spaced at 20
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
Sections are set to three feet, one mile traveled will result
in an Area of 1.5 Lane Miles covered.
ADJUST RATE: In AUTO control with RATE selected,
pressing “+” or “-” will change the TARGET
RATE by the amount
entered for ADJUST
RATE. This allows
the operator to
make changes to the
TARGET RATE quickly. To disable this feature, simply enter
“0” for a value.

minimum ow rate for the nozzles. Enter the minimum
ow rate in gallons
per minute (liters per
minute) based on the
nozzles being used, for
the entire section width
of the applicator. DO NOT enter the target
ow of your spray application. For example: If the minimum
ow rate for the nozzle you are using is .22 GPM at their
minimum recommended pressure and your section 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. The Warning LED will FLASH whenever
the system is applying at Minimum Flow Rate but the Au-
dible Alarm will not sound. This value should be checked/
changed for each dierent nozzle that you use.

FLOW CAL: This position is used to calibrate the flow
meter for accurate liquid measurement. Enter the Micro-
Trak liquid cal number
printed on the
flowmeter tag (See
Illustration 7) The Flow
Cal number should
not be changed during operation because
a change in the Flow Cal number will also
change some counter values.

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 Flow-
meter Calibration in Appendix D on page 36.)

TEST SPEED: Choose the value to be used for simulating
speed for performing Pre-application System
checkout. The console will use this speed
for simulating spraying operations. The test
speed value is only used while in calibration
mode. Once CAL is exited, the Test Speed
value is reset to zero.
Please refer to Pre-application System Checkout on page 26
for details.
EXITING CALIBRATION: Upon completion of the
calibration process, exit calibration. Basic calibration is
now complete. Please refer to Pre-application System
Checkout section to confirm overall system performance.
SPEED CAL: This position is used to calibrate the speed
sensor for accurate speed and distance measurement.
When this position is
selected, the display
will show the SPEED
CAL value along with
"CAL" on the display. In English units, the
SPEED CAL number is displayed in inches,
in metric it is displayed in centimeters. The SPEED CAL is
factory-calibrated for use with an Astro GPS Speed Sensor.
See the table below for SPEED CAL numbers for other
types of GPS speed sensor or radars. See Appendix B for
procedure to calibrate if using a Magnetic Speed Sensor.

AUTO SHUT OFF: Selecting the TANK LEVEL position on
page two (2) allows the user to turn the AUTO SHUT OFF
feature On or Off by using the “+” or “-”
(Reset) keys. While in AUTO with the AUTO
SHUT OFF turned off
automatic control
will “freeze” the
current flow when
HOLD is pressed. With the AUTO SHUT OFF
ON, the servo valve will run towards closed for 4 seconds
each time HOLD is selected or ground speed is stopped.
This is useful for stopping flow when using auger or belt
delivery systems.
AUTO DELAY TIME: Used to delay adjustment of the
servo valve (in AUTO) until section or ON/Off valves have
completely opened. Selecting the RATE
position on page two (2) allows the user to
change the AUTO DELAY TIME by using the
“+” or “-” (Reset) keys to vary the delay
time from 0 (no delay) to

START TIME: Selecting the VOLUME/MINUTE position
on page two (2) allows the user to change the START
TIME for the control
valve. The START TIME
can be adjusted from
Off to 2.048 seconds.
The START TIME runs the Control Valve
towards open for the amount of time
(seconds) set, when a HOLD to RUN transition occurs. The
control valve may be used to stop hydraulic flow and can
be the cause of an undesirable delay for the Servo to return
to normal operating flow. The START TIME cal value can be
used to reduce this delay.
MINIMUM ALARM SPEED: Selecting the VOLUME
position on page two
(2) allows adjustment of
the MINIMUM ALARM
SPEED. Pressing the
“+” or “-” (Reset) keys will adjust the
MINIMUM ALARM SPEED from 0.1 to 99.9
mph or kph. When the ground speed is
below the MINIMUM ALARM SPEED, an
Application Rate error will not generate
an Audible Alarm. Tank empty and Float alarms are not
disabled. Setting the MINIMUM ALARM SPEED to Off will
disable the function and allow audible warnings at any
speed. This setting can be used to disable nuisance alarms
while stopping and starting.
