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 SprayMate
TM 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 SprayMate TM 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.

Speed Sensor Options
NOTE: In addition to the standard Hall-effect magnetic
speed sensor, the
SprayMate TM II 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 SprayMate TM 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.
VANSCO
T M
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 SprayMate TM II may also be interfaced with most popular
radar ground speed sensors. An adapter cable is re quired for
proper interface.
