Speed sensor for the sprayer
The speed sensor is located at the inside of the sprayers right wheel. It
measures the sprayer's ground speed.
It is an inductive type that requires a metallic protrusion to pass by it to
trigger a signal.
To trigger, a speed ring is used. It should be adjusted, so that the sensor
is pointing to the middle of the gaps (vertically) in the speed ring.
Assure that the speed ring is correctly fitted to the wheel, so that the
arrow (A) follows the forward rotation of the wheel.
Recommended distance (B) between protrusion and sensor is 3 to 6
mm. Check this in the whole circumference when spinning the wheel.
The distance tolerance should be +/- 0.5 mm.
Correct fitting is indicated by a constant flashing from the sensor, when
the wheel is rotating.
The pictures show different examples of the sensor with brackets - these
may differ a little depending on the sprayer model.
Speed sensor for the tractor
It is possible to connect a speed sensor from the tractor's gearbox or
radar/GPS to the controller. A speed/switch wire harness (A) and
extension cable are needed to connect the speed sensor to the
Controller/Terminal.
