Multi Pro 5700--D Page 7.1 -- 7 Sonic Boom System (Optional Kit)
Sprayer Operation on Level Turf
During sprayer operation with the sonic boom switch in
the automatic position (sonic boom light is illuminated),
the boom mounted sonic boom sensors continually
send impulse signals and then receive echos as the sig-
nals bounce off the turf. The electronic control unit
(ECU) determines the sensor distance from the ground
based on the elapsed time between the sensor signal
generation and the received echo. As long as the sensor
height remains the same as the calibrated height, the
spray boom will remain at a fixed height from the ground
for spraying accuracy.
On level turf, the boom sensors continually send signals
and receive echoes that determine that the booms sec-
tions are at the calibrated height. Thus, there is no need
to change boom height. The boom actuators will not be
energized and the boom sections remain at the correct,
level position.
