Installation
Mounting the Display Console
Select a mounting location which seems most workable, and
that best fits your needs. It should be 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 selected location, mark holes,
drill 1/4" (7mm) holes and mount bracket with bolts, lockwash-
ers and nuts provided. (Use self-tapping screws if not practical
to use bolts.) See Illustration 1A.
Put rubber washers on carriage bolts and put the bolts through
the bracket holes from the inside out.Loosely attach the mount
knobs onto the bolts. Place console over carriage bolt heads
and tighten knobs to secure the console. See Illustration 1B.
Mounting the Run/Hold Switch Kit
Remove the mount knob from either side of the console. Install
the bracket over the carriage bolt and along side the console
bracket. Install the mount knob on the carriage bolt and
tighten to secure the console and run/hold switch bracket in
place.
Install the switch in the bracket and attach the quick
disconnects on the switch harness to the switch. Then install
the switch harness connector into the mating connector (gray
tie) on the console harness. An optional power (console on/off)
switch kit is also available, (P/N 14360).

Attach black wire to
terminal or lead that is
“hot”with ignition on.
Do NOT connect
the red wire.
Tie back and tape off.
Carefully route switch
cable to a 12-volt source.
4-amp in-line fuse (NOT PROVIDED) required for unprotected circuits.
Electrical Installation
This section explains how to connect your SprayMate II to a 12-
volt power source, and how to connect your boom shut-off
valves.
NOTE: The SprayMate II must be connected to a 12-volt DC
negative ground electrical system.
POWER/BATTERY CONNECTION:
Locate the power cable for the SprayMate II and route to the
battery. When routing cable to console, avoid areas where the
cable may be subjected to abrasion or excessive 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 SprayMate II console by plugging the
2-pin W/P tower on the power cable into the 2-pin W/P shroud
of the display console.
ON/OFF SWITCH CONNECTION:
The SprayMate II system includes a provision for either using a
switched (ignition) source or an optional power switch to turn
the system on.
If the optional power switch is used, simply mount the switch
bracket as shown on page 7, 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, route the ignition cable
(P/N 14314) from the console to the switched source, plug the
connector into the mating plug for the console and connect
the black wire to the switched power source as shown in
Illustration 3 (terminal or wire). Do NOT connect the red wire.
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.
Your SprayMate 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.

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) -
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.
Magnets
Illustration 5A
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 E.
Speed Sensor Installation
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 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 SprayMate 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 6.
NOTE: Observe magnet polarities (see previous section).

SENSOR IDENTIFICATION CHART
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 SprayMate II Wiring Diagram on page 10.
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 SprayMate II Wiring Diagram on page 10.
Speed Sensor Options
In addition to the standard Hall-effect magnetic speed sensor,
the SprayMate II may be interfaced with a variety 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 MT-NH3 II may also be interfaced with most popular radar
ground speed sensors. An adapter cable is required for proper
interface.
GPS Speed Sensor Interface
The MT-NH3 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.
SEE APPENDIX E FOR LIST OF ADAPTER CABLES FOR RADAR.

Mounting and Plumbing Flowmeter
The Flowmeter must be installed in the main boom
line after any strainers, return lines, or valves. Securely
mount flowmeter (hardware not supplied) in a vertical
position in an area away from intense vibration. DO
NOT install flowmeter closer than 12" to the servo
valve or the boom shut-off valves. The flow meter 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-
nections using appropriate fittings without the use of
reducers, elbows or sharp bends for a minimum of six
inches (15 cm) either side of meter. See Illustration 7.
Save plastic plugs to protect flowmeter during
storage. (The flowmeter may need periodic cleaning,
so it should be easy to remove.)

Hydraulic Cylinder Mounting
Remote Run sensor on hydraulic cylinder. Magnet and sensor are in line
when equipment is lowered and operating.
Remote Run/Hold
The run/hold sensor cable has a BLACK body and a GRAY tie near
the 3-pin M/P connector and mates with the main harness cable
having a GRAY 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. 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. The solenoid valves will also shut off. 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 blue jumper wire in the dust cover and splice on an
appropriate length of wire to reach your switch. Do not
connect to a switch with power.
When switch is closed, console is in RUN. When the switch is
open, the console is in HOLD.

Care and Maintenance of your SprayMate 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.
