Text of alarm message
Meaning
The signal voltage is outside of the valid range.
Valid range: 0.5 V to 4.5 V
The sensor is used both for DISTANCE-Control and for TRAIL-Control, and is therefore
calibrated with each of these systems.
BOOM
Defective slope sensor.
The slope sensor installed on the boom of the field sprayer is defective or was not
configured.
The signal voltage is outside of the valid range.
Valid range: 0.5 V to 4.5 V
Defective right US-sensor.
The first echo of the ultrasonic sensor is not coming back. Sensor or cable is defective.
Defective left US sensor.
The first echo of the ultrasonic sensor is not coming back. Sensor or cable is defective.
Sensors are disturbed.
Short signal interruption with all sensors.
An actuator might be connected to the sensor ground (GNDE) in the junction box.
Defective height angle sensor.
Angle sensor that measures the height of the lift pole is defective.
This error message only appears on a few field sprayers that have manufacturer-specific
configuration.
DISTANCE-Control: Alarm messages during calibration
Text of alarm message
Meaning
No right ultrasonic signal.
There is no echo coming back for more than 50% of the trigger impulses.
No left ultrasonic signal.
There is no echo coming back for more than 50% of the trigger impulses.
The slope sensor is not correctly
installed.
The signal voltage is outside of the valid range.
Valid range: 0.5 V to 4.5 V
The slope angle sensor is not
correctly installed.
The signal voltage is outside of the valid range.
Valid range: 0.5 V to 4.5 V
The ultrasonic sensors are not
correctly installed.
The sensors are connected inversely. (Left and right were inverted in the junction box)
No slope sensor signal.
In the second calibration step, the slope sensor did not detect a change in the signal.
No angle sensor signal.
In the third calibration step, the angle sensor did not detect a change in the signal.
Outputs are swapped.
The hydraulic valves were connected wrong.
Sensors are disturbed.
Short signal interruption with all sensors
