Boom Level Changed by Operator During Automatic Operation

During sprayer operation with the sonic boom switch in
the automatic position (sonic boom switch light is illumi-
nated), the boom mounted sonic boom sensors continu-
ally send impulse signals and then receive echoes as
the signals bounce off the turf. The Toro electronic con-
troller (TEC) determines the sensor distance from the
ground based on the 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 distance from the
ground for spraying accuracy.
If the sprayer operator should press a boom lift switch
while in automatic operation, the TEC energizes the ap-
propriate boom lift control electrical relays. The ener-
gized relays cause the boom actuator to raise or lower
the boom section. The relays will stay energized as long
as the operator keeps the boom lift switch pressed. The
sonic boom light will flash while the boom lift switch is be-
ing depressed. If one boom is moved by the operator,
the other boom continues to function automatically.

If a boom is raised by the operator while the Ultra Sonic
Boom System is in automatic operation, that boom will
remain in the raised position until the boom lift switch is
pressed to lower and released which will re--engage au-
tomatic sonic boom operation on that boom section.
If a boom is lowered by the operator while the Ultra Sonic
Boom System is in automatic operation, that boom will
lower until the boom lift switch is released. The automat-
ic sonic boom operation will be re--engaged as soon as
the lift switch is released from lower.
NOTE: To re--engage automatic sonic boom operation,
the boom lift switch must be pressed to lower and re-
leased. Pressing the boom lift switch to raise will not re--
engage automatic operation.
