Speed Sensor Options
The SprayMateTM Plus must be connected to a speed sensor to utilize its calculating function.
Several possible options are listed below:
ASTRO SERIES OR OTHER GPS SPEED SENSOR INTERFACES
The SprayMate Plus is designed to easily connect to the Micro-Trak Astro series speed sensor. It also may be used with most
GPS speed sensors that output a pulsed signal, such as the Squibb-Taylor®SkyTrak or Dickey-John®GPS speed sensors. An
adapter cable may be required.
MAGNETIC WHEEL SENSOR
This system uses magnets attached to a wheel hub or drive shaft and a hall-effect sensor. The movement of the magnets near
the sensor creates an electrical pulse which the console uses as a speed input. The system must be carefully calibrated to
ensure accurate readings. SEE APPENDIX B FOR MAGNETIC SENSOR INSTALLATION.
VANSCO™RADAR SPEED SENSOR AVAILABLE FROM MICROTRAK DEALERS & DISTRIBUTORS
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 Plus may also be interfaced with most popular radar ground speed sensors. An adapter cable is required for
proper interface.
SEE Appendix K FOR LIST OF ADAPTER CABLES FOR RADAR.
ASTRO SERIES GPS SPEED SENSOR INSTALLATION:
RECEIVER: The GPS receiver may be mounted either externally (roof of the cab or other place
with a clear view of the sky) or inside the vehicle cab. However, if mounted inside the cab there
may be some loss of accuracy due to blockage of satellite signals. For most reliable operation,
mount the GPS receiver in a location where it has an unobstructed view of the sky. Mount the
receiver using the integral magnet or the included self-adhesive fastener tape. If using the
fastener tape - clean the mounting location, remove the plastic backing, and press firmly to the
surface.
WIRING: Route the 10 foot cable from the receiver into the cab (if receiver is externally
mounted). Avoid sharp edges or heat sources. The rectangular module is roughly the same size
as the connector and will fit through the same opening.
MODULE: The small potted module includes a power LED and a GPS status LED. The module can be mounted in a visible
location using the included self-adhesive fastener tape, or placed out of sight.
• Power LED (closest to connector) : On when 12VDC is connected
• GPS Status LED (closest to receiver): Flashes when the GPS receiver is active and scanning for a satellite. When a signal is found, it will
remain on. If the GPS system fails, the light will turn off.
CONSOLE CONNECTION: Connect the short cable from the Astro to the 3-pin connector labeled SPEED on your console.
Proximity Sensor
Micro-Trak® also offers a proximity sensor - P/N 01554 Gear tooth sensor kit. It is useful in situations where it is impractical or
inadvisable to use a flowmeter to monitor flow of material. It can also serve as a Speed sensor. The 01554 Gear tooth sensor
responds to the close presence of ferrous metals and sends a signal to the console via the Flow or Speed connection. The
recommended air gap between sensor and moving part is 1/16” (tip: use a U.S. dime as a gauge). To calibrate the system to use
this sensor for Flow, use the Appendix D - Fine Tuning Flowmeter Calibration, for Speed, use Appendix C - Fine Tuning Speed/
Distance. For use as a Flow monitor for PWM systems, use Appendix G - Closed Loop Live
Calibration for PWM control.

Optional Equipment - Switches
Contact a Micro-Trak® dealer or distributor for more information on these accessories.
A Dealer Locator can be found online at http://www.micro-trak.com/where-to-buy/dealer-locator.
Micro-Trak offers two options for automatically controlling the operation of the SprayMate Plus system. Both solutions
mount directly to your implement and control run/hold as the machine is operated. Installation locations vary by the type of
machinery used. Both types of Implement Switch join to the “Run/Hold” connection on the Branch Harness.
Whisker Switch Assy.- P/N 18541
Simply mount the Whisker Switch Assembly near a moving part of an operating mechanism on your implement (additional
extension cables may be needed). The connector labelled “SafeGuard Run/Hold” is wired Normally Open. The default polarity
for the SprayMate Plus Run/Hold circuit is preset to “Closed”, meaning pressure on the switch tip causes the system to “Hold”.
See figure 6. The polarity setting can be accessed in Special Calibration settings (see page 23) - it is called “Hold Input Polarity”.

Remote Run/Hold Sensor Kit- P/N 01535
The Remote Run/Hold Sensor consists of a Hall-effect proximity sensor and a magnet. Mount the sensor near a moving part
of an operating mechanism on your implement; mount the magnet on the moving part (additional extension cables may be
needed). The sensor is wired Normally Open; the default polarity for the SprayMate Plus Run/Hold circuit is preset to “Run”.
Moving the magnet close to the sensor tip causes the system to “Hold”. See figure 7. The polarity setting can be accessed
in Special Calibration settings (see page 25) - it is called “Hold Input Polarity”. More extensive instructions on installing the
Remote Run/Hold Sensor can be found in Appendix A.

16
Installing Flowmeter
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. See figure 8. 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.
Installing Flow Sensor Cable
The flow sensor cable has a GREEN sensor body and joins the
3-pin connector on the wiring harness marked FLOW. See
figures 9 and 10.
1. Screw threaded sensor into hole of flowmeter until seated.
2. Gently tighten 3/8” jam nut to secure sensor in place.
3. Uncoil flow sensor cable and route it to wiring harness.
4. Align connectors and press firmly together until locking tab
clicks into place.
5. Secure cable with plastic ties provided.
See SprayMate™ Plus Wiring Diagram on page 7.
NOTE: Sensors with GREEN bodies can be used for either
SPEED or FLOW but not for REMOTE RUN/HOLD.

Care and Maintenance
At end of application season, thoroughly flush Flowmeter with clean water, and drain completely .
• 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 - Noryl GTX. If you are in doubt, contact the chemical manufacturer.
P/N 18757 - 150 PSI
P/N 18758 - 300 PSI
Installing Pressure Sensor (Optional)
The pressure sensor should be installed in the main line of flow as
close to the section shut-off valves as possible. The sensor requires a
1/4” - 18 NPT fitting. See figure 11.
1. Install the sensor in the plumbing line.
2. Join the cable to the 3-pin Packard™ connector on the sensor.
3. Route the cable (and extension cables, if needed) to the console
location - avoid sharp surfaces and heat sources.
4. Join the cable to the PRESSURE connection on the wiring
harness - align connectors and press firmly together until locking
tab clicks into place.

17
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 Figure 14. 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 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.
NOTE: For Inline operation, the servo valve is installed in the
main spray line as shown in Figure 15.

Bypass Valve
With oversized pumps, it may be necessary to install a
bypass valve. This valve allows excess flow to return to
the tank. This in turn reduces the pump output to the rest
of the system. See Figure 12. Adjustment of this valve is
covered in the Pre-Field System Checkout, page 32.

Manual Pressure Relief Valve
If you have a positive displacement pump or a centrifugal
pump capable of generating excessive pressure, you must
install a pressure relief valve and adjust it to a safe maxi-
mum pressure. If a positive displacement pump is operated
without a pressure relief valve, pump or other plumbing
components may be damaged. See Figure 13.

• Operates in LIQUID or NH3 application modes in Metric, English or Turf units:
- English: Area units are acres, distance is feet, ow is gallons or lbs-NH3 per minute and application rates are in
gallons or lbs-N per acre.
- Metric: Area is measured in hectares, distance is in meters, ow is liters or kg-NH3 per minute and application rates
are in liters or kg-N per hectare.
- Turf, where the area units are in 1000 Square Feet, distance is in feet, ow is gallons or lbs-NH3 per minute and
application rates are in gallons or lbs-N per 1000 Ft2.
• The following can be selected for display: Volume, Area (each have 3 independent counters), Distance, Pressure, Speed,
Application Rate, Tank Level, Volume/Minute.
• SprayMateTM Plus can operate with 1 to 3 Sections with individually adjustable widths. Three section switches are located
on top of the Console or external section switches can be used.
• Flow Input can be calibrated to allow use of a variety of meters or encoders for feedback
• Speed Input can be calibrated to allow use of a variety of speed sensors.
• Tank size can be entered for quick reset of the Tank Level. A Tank level can be set to generate an alarm (LED, message and
audible) when the calculated tank level is less than the set point.
• Warning messages for No Speed and No Flow while in Automatic control and Application Rate position.
• When off Target while under auto control an adjustable ‘Rate Alarm Threshold’ will determine when a warning is given
(audible and red Warn LED flashes).
Rate Control
• Automatic control maintains a set Target Application Rate, and Manual control (can be disabled in “Special” calibration)
allows the operator to manually control the Application rate.
• When in the RATE position and in automatic control, the Target Application Rate can be increased or decreased
(Increase/Decrease buttons) by a selectable Adjust Rate.
• A Control Response setting (Control Speed) allows the control valve speed to be optimized for the system and the servo
control can be set for Bypass or Inline congurations (Valve Polarity).
• A Minimum Flow (Gallons or Liters per minute) feature controls minimum ow to system. Useful for maintaining nozzle
spray pattern - use nozzle manufacturer’s charts to calculate minimum ow value.
• ‘Auto Delay Time’ can be set from 0 to 4 seconds to delay Automatic control when starting application, This allows time for
shut-o valves to completely open and ow to stabilize before attempting control.
• When in Manual control and in either the VOLUME/MINUTE or RATE positions, the Application Rate can be increased or
decreased using the Increase/Decrease buttons.
• When in Automatic control and in the VOLUME/MINUTE position and in Hold, the Flow Rate can be increased or decreased
using the Increase/Decrease buttons (Standard DC drive only).
• When in Automatic control, if no ow signal is detected for a period of time, the Emergency Stop feature will stop ow
(close the control valve) and display the “noFlo” warning message.
• ‘Auto Shut O’ can be enabled to use the Standard DC control valve to stop ow (close control valve) when in Hold, no
sections are on, or no ground speed in Automatic control.
Feature Summary
Basic Features

19
• Supervisor Lockout Mode - activated in Special Calibration mode. When locked, it allows operator to view calibration
numbers but prevents changes. It also allows only Data Set 1 to be cleared (volume, area and distance) but prevents
clearing Data Sets 2 and 3.
• Can be set to work with either Standard or FTW (Flow Three Way) Section valves.
• Selectable servo drive options, Standard DC servo and Pulse Width Modulation (PWM) with adjustable PWM frequency and
PWM maximum/minimum limits.
• Multi-Function Output with selectable functions:
- Always OFF: Output is unused.
- Always ON: Output high whenever the console is powered on.
- Relief Valve: Output high when in Hold or all sections o.
- Master: Output high when in Run and at least 1 section on.
- Flush: Output high for settable time after a Run to Hold transition and a settable pause interval. Audible indicator of
the Flush cycle completion.
-F-FLO (Fixed Flow Trigger) - On when the Flow per Minute reaches a User-settable fixed total flow rate.
-P-FLO (Proportional Flow Trigger) - On when the Flow per Minute reaches a User-settable flow rate, proportional to
active sections.
-Sect - On in Run - unaffected by sections
• Open Loop and Closed Loop Override control (PWM drive)
• A “Quick Start” feature can be enabled for triggering immediate application when in Automatic operation. Two different
methods are available:
Quick Start - SPEED provides an instant simulated speed whenever the system goes from HOLD to RUN. This triggers
instant application using Start Speed and Start Speed Time - Special Calibration parameters.
Quick Start - VALVE provides a “jump start” to open the control valve by running it immediately after some movement
is detected. This triggers instant application using Start Time (STD) or Start Percentage (PWM) - Special Calibration
parameters.
• ‘Application ID’ setting - assigns a unique ID number to the data to identify specific jobs or vehicles
• Audible alarm output (can be disabled) for notification of Rate errors over ‘Rate Alarm Threshold’ or Tank level below set
point, or Pressure above or below Hi or Low alarm level.
• Optional Pressure Sensor to monitor system pressure. SprayMate Plus can also be configured for pressure based flow
control.
• Fixed Minimum Flow feature sets an absolute minimum value for flow. This ensures that the flow rate is never less than the
lowest range of the flowmeter - preventing the flowmeter from stalling.
Serial Port
• Selectable VRA Serial Protocol (Micro-Trak® or Raven®) to interface with GPS/Mapping Controllers for Variable Rate
Application (VRA) including Target Hold.
• User can override the GPS/Mapping Controller to apply a rate above or below the prescription rate or override Target Hold.
• Serial commands to support AVL (Automatic Vehicle Location) data collection methods: Totals data list includes the
Application ID, and all data sets. Equipment data list includes Controller Type, Application ID, section widths, measurement
units and application mode.
