Installation (cont.)
Electrical Installation
This section explains how to hook-up your SprayMateTM II to
a 12-volt power connection, and how to connect your boom
shut-off valves.
The SprayMateTM II must be connected to a 12-volt DC
negative ground electrical system. Use your test light to
locate a terminal or wire connected to your ignition switch
which is “hot” when the ignition is turned on and “dead”
when the ignition is off.
POWER/BATTERY CONNECTION
Locate the power cable lead on the SprayMateTM II harness
and route to the battery. In routing cable to console, avoid
areas where the cable may be subjected to abrasion or exces-
sive heat. Attach the BLUE wire (ground) to a screw or bolt
on the equipment frame. See Illustration 2. Be sure there is a
good metal-to-metal contact. Connect the ORANGE wire to
the positive battery terminal.
Connect the power to the SprayMateTM II console by plugging
the 2-pin M/P tower on the power cable into the 2-pin M/P
shroud of the display console.
ON/OFF SWITCH CONNECTION
The SprayMateTM II system harness includes a provision for
either using a switched (ignition) source or the optional
power switch to turn the system on.
If the switch is used, simply mount the switch bracket as
shown on page 11, and plug the connector into the mating
cable from the console. If you want to use the ignition
switch to turn the system on and off, using the 72” 2-wire
extension cable, plug the connector into the mating plug
for the console and connect the black wire to the switched
power source (terminal or wire). DO NOT connect the red
wire.
Your SprayMateTM II is equipped with an electronic memory
which does not require a constant supply of power to retain
daily totals or calibration values. This type of memory
conserves battery power and will not discharge the vehicle’s
battery when equipment is not in use.

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 (meters). Divide that measurement
by 20 for English and Turf units, or by .5 for Metric units, and
then round up to the nearest even number (always use an
even number of magnets). That number will be the minimum
number of magnets required for the installation.
Example in English/Turf units: If your revolution measurement
is 97 inches, dividing that number by 20 gives you a value of
4.85. Rounding 4.85 up to the nearest even number is 6. For
this example, the minimum number of magnets required is 6.
Example in Metric units: If your revolution measurement is
2.5 meters, dividing that number by .5 gives you a value of
5. Rounding 5 up to the nearest even number is 6. For this
example, the minimum number of magnets required is 6.
The magnets provided by Micro-Trak® are marked with a
punched dashed line on the SOUTH pole side of the magnet.
See Illustration 5A.
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 5B.
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 5C.
PLEASE NOTE: If you have purchased a Vansco speed
sensor, disregard the following section on magnetic
speed sensors and install the Vansco as described in the
instructions included with the unit.
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.

Attaching Magnets
The magnets are attached to a wheel hub or drive shaft and
the speed sensor is mounted directly over the magnet. When
the wheel or drive shaft begins turning, a speed impulse
is sent to the SprayMateTM 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 following requirements.
See Illustration 6.
NOTE: Observe magnet polarities (see previous page).

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 SprayMateTM II Wiring
Diagram on page 10.
Connecting the Speed Sensor Cable
The speed sensor cable has a GREEN sensor body and mates
with the main harness cable having a YELLOW cable tie near
the 3-pin M/P connector. Make certain that you install the
correct sensor cable and connect it to the correct connector
on the main harness. The speed sensor and the flow sensor
are identical, but must be connected to the proper harness
connector. The speed sensor always connects to the main
harness lead with the YELLOW tie and flow sensor always
connects to the main harness lead with the GREEN tie. See
SprayMateTM II Wiring Diagram on page 10.

Speed Sensor Options
NOTE: In addition to the standard Hall-effect magnetic
speed sensor, the SprayMateTM II may be interfaced with a
variety of other speed sensing equipment. Several options
are listed below.
ASTRO SERIES OR OTHER GPS SPEED SENSOR INTERFACES
The SprayMateTM II may also be used with most GPS speed
sensors that output a pulsed signal, such as the Micro-Trak®
Astro II and 5, SkyTrak or Dickey-John GPS speed sensors. An
adapter cable may be required.
VANSCOTM 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 SprayMateTM II may also be interfaced with most popular
radar ground speed sensors. An adapter cable is required for
proper interface.

Manual Pressure Relief Valve
If you have a positive displacement pump or a centrifu-
gal pump capable of generating excessive pressure, you
must install a pressure relief valve and adjust it to a safe
maximum pressure. If a positive displacement pump is
operated without a pressure relief valve, damage may result
to pump or other plumbing component. See Illustration 9.

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

16
Servo, Throttling Valves
For BYPASS installations, the servo valve installs in an
unrestricted return line to the inlet of the pump or directly
into the tank. The console must be calibrated for bypass
operation, see Calibration section. DO NOT install the servo
valve closer than 12” to the flowmeter. The servo valve has
a flow direction decal on it. Make certain that the actual flow
direction matches the decal on the servo valve. DO NOT
install the servo valve in the agitation line. Slow response
time and marginal operation may result. The return line
should tee from the main line just after the throttling valve.
See Illustration 11. The throttling valve is used to limit the
output (set maximum output) of the pump to the flowmeter
and servo valve. The throttling valve is adjusted to put the
servo valve in its optimal operating range. Please refer to
Pre-Field System Checkout on page 32-33 for proper valve
adjustment procedure.
The servo valve connects directly to the 3-pin connector on
the main harness. If more length is required, use a 3-pin W/P
extension cable of the appropriate length.
IMPORTANT NOTE: If using the SprayMateTM II with an
old-style Micro-Trak® servo valve, the valve voltage must
be set to 8 volts. See “Special” Calibration Valve Voltage
section on page 27.
NOTE: The servo valve may be installed in the main spray
line as shown in Illustration 12. For In-line installations,
you will need to calibrate the system for INLINE operation,
see page 25.

Care and Maintenance of your SprayMateTM II
Console
Store the console in a cool dry location if it will not be used for an extended period of time, such as during the
off-season. As with any electronic equipment, use care in cleaning so that water or other liquids do not enter
the case. Thoroughly flush Flowmeter with clean water, install plastic shipping plugs and keep from freezing.
Precautions
• The input pressure on the glass-filled nylon flowmeter FM750 GFN should not exceed 100 PSI (689 kpa).
• Do not expose the flowmeter to liquid temperatures exceeding 130 degrees F (55 degrees C).
• Some chemicals may damage the turbine material. If you are in doubt, contact the chemical manufacturer.

correct sensor cable and connect it to the correct connector
on the main harness. See Illustrations to the right.
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 implement
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 magnet is away from the sensor, the console
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
require additional extension cables which are available
in 5 ft. (1.5 m), 10 ft. (3 m), 15 ft. (4.5 m), 20 ft. (6 m) and
25 ft. (7.6 m) lengths.
• You may also use a toggle or other type switch. Simply
cut the 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.

The SprayMateTM II is capable of displaying information in
American English or standard Metric measurement. The
SprayMateTM II is shipped from the factory programmed
for English. Note that the following procedures will also
load factory default calibration values. To simply change
units without loading defaults, see the “Special” Calibration
section.
METRIC
• You must be in HOLD or have all booms OFF to enter
Cal. To activate the Metric mode, turn power OFF and
place the rotary switch at “AREA.” Hold down both the
“CAL” and “-” keys and turn power ON. See Illustration 13.
The console will display LOAd for two seconds. Once
LOAd is displayed, release the two keys. To “lock-in”
Metric mode you must enter and exit calibration. Press
and hold the CAL key until “CAL” icon appears on the
display. The console is now in calibration and Metric
mode is selected. Exit CAL by pressing and holding
the “CAL” key until CAL disappears from the display
(approximately 1 second). NOTE: you must exit CAL to
lock in Metric units.
ENGLISH
• You must be in HOLD or have all booms OFF to enter
Cal. To activate the English mode, turn power OFF and
place the rotary switch in the VOLUME position. Hold
down both the “CAL” and “-” keys and turn power ON.
The console will display LOAd. Once LOAd is displayed,
release the two keys. To “lock-in” English mode you
must enter and exit calibration. Press and hold the CAL
key until “CAL” lights on the display. The console is now
in calibration and English mode is selected. Exit CAL by
pressing and holding the “CAL” key until CAL disappears
from the display (approximately 1 second). NOTE: you
must exit CAL to lock in English units.
NOTE: In metric, the width will have a decimal point, in
English there is no decimal point. Also, changing from English
to Metric mode may change or alter any previously entered
calibration values. After switching measurement modes, con-
firm that all calibration values are correct.
IN ALL CALIBRATION OPERATIONS:
1. Turn all boom switches OFF or put system in “HOLD”.
2. Press and hold the “CAL” key for 1 second to select the
calibration mode. The console display will display the
“CAL” icon, the currently selected calibration value, and
the red warning light will turn on.
3. Turn the rotary dial to the desired “CAL” position. Then
use the “+” or “-” key to adjust the displayed value
up or down as needed. Adjust ALL necessary values.
See Illustration 14.
4. Hold the “CAL” key again for 1 second to exit calibration.
“CAL” will disappear from the display.
NOTE: You must exit CAL to save changes.

To enter or change any of the system’s calibration values,
you must enter calibration mode. To enter calibration mode,
STOP the vehicle, turn all booms OFF or put the console in
HOLD and press and hold the CAL button until the “CAL” icon
appears (approximately one second). (NOTE: Calibration
may be entered while moving, but it is not recommended to
attempt calibration while the vehicle is moving.) The console
will remain in calibration mode, with the RED warning light
illuminated until you exit calibration or turn power OFF.
Once in calibration mode, you may change any one, all, or
none of the values, in any order.*To select a calibration
position, simply turn the rotary selector to the desired
position. Calibration positions are identified by the WHITE
labeling on each side of the rotary selector. All values are
entered and adjusted using the “+” and “-” buttons on the
front panel.
* TEST SPEED MUST BE LAST.

Entering Calibration Values
TARGET RATE: Enter the value for the
desired target application rate in gallons per
acre (liters per hectare) or lbs. of N per acre
(kgs of N per hectare). This is the application
rate that the console
will lock onto when
operating in AUTO. TARGET
RATE RATE
ADJUST RATE: Enter the value for the desired amount
of change in gallons per acre (liters per hectare) to be
used for making on-the-go rate adjustments
when operating in AUTO. For example, if a
value “1.0” is entered,
you will be able to
increase or decrease
your application rate
in one-gallon (liter) or lb. (kg) increments during operation in
AUTO. To disable this feature, simply enter “.0” for a value.
ADJUST
RATE TANK Your “working” width per boom section will be the number
of nozzles on the boom section times the nozzle spacing in
inches (mm). For example, if you have 8 nozzles spaced at 12
inches, the working width of the boom section is 96 inches.
See Illustration below.
CAUTION: If spray-lines are pressurized, nozzles may spray
during this step.
WIDTH: Enter the effective working width, in inches (meters)
for the boom section
currently shown on the
display. It is simplest to
start with all booms ON
and then turn each boom OFF, from left to
right, after calibrating the width. Note that
the system must be in RUN (not HOLD) to
display boom numbers. Repeat this procedure
for each boom section. Enter a value of “0”
(.000) for any unused boom sections.

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

FLOW CAL: This position is used to calibrate the flow-
meter for accurate liquid measurement. Every flowmeter
is calibrated with
water at the factory
and assigned a “FLOW
CAL” value to make it
operate properly with
the SprayMateTM II console. This number
is stamped on the metal tag attached to
the flowmeter. See Illustration 17. 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 Flowmeter Calibration
in Appendix C on page 45.)
