AutoBoom® Calibration & Operation Manual
Booms overreact or
oscillate during calibration.
Ultrasonic sensors
registering objects below
the sensor causing faulty
readings.
Retry calibration of the system over open ground or
consistent crop canopy.
Inner and outer sensor
connections are reversed.
Check the inner and outer sensor connections and
switch if necessary.
Faulty ultrasonic sensor
readings.
Check the sensors and cabling and replace as
necessary.
Speed setting is too high.
Decrease the speed setting.
Sensitivity setting is too
high.
Decrease the sensitivity setting.
Hydraulic flow is too high
(pull-type sprayers only).
Decrease the hydraulic flow to the AutoBoom circuit
remote.
Orifices are missing from
the AutoBoom valve.
Reinstall orifices into the AutoBoom valve.
Booms fully raise during
calibration and do not lower.
Inner and outer sensor
connections are reversed.
Check the inner and outer sensor connections and
switch if necessary.
Ultrasonic sensors are
giving poor readings.
• Check cabling to the sensors.
• Verify the sensor surface is clean.
• Verify no obstructions or boom components are
interfering with sensor readings.
Hydraulic connections are
improperly connected.
• Check hydraulic connections.
• Reverse the direction of the hydraulic lever (pull-
type sprayers only).
The electrical connections
to the AutoBoom valve are
reversed.
Check the connections to the AutoBoom valve to
ensure the harness cable connections are inserted to
the correct ports.
Speed setting is too high.
Decrease the speed setting.
Sensitivity setting is too
high.
Decrease the sensitivity setting.
Hydraulic flow is too high
(pull-type sprayers only).
Decrease the hydraulic flow to the AutoBoom circuit
remote.
Booms fall to the ground
during calibration.
The proportional valve
connections are reversed
on the AutoBoom valve.
Check the connections on the AutoBoom valve to
ensure the harness cable connections are inserted
into the correct ports.
Hydraulic connections are
improperly connected.
• Check the hydraulic connections.
• Reverse the direction of the hydraulic lever (pull-
type sprayers).
Malfunctioning proportional
valve.
Turn the set screws in the proportional valve to verify
the booms raise during calibration.
• If booms raise, troubleshoot the electrical system
and/or AutoBoom node.
• If the booms do not raise, troubleshoot the hydraulic
system and/or AutoBoom valve.
Hydraulics are not
activated (pull-type
sprayers only).
• Verify the hydraulics are activated.
• Ensure hydraulic flow going to the AutoBoom valve.
