DISTANCE-Control
Safety mechanisms
The job computer software has several safety mechanisms that automatically deactivate the
DISTANCE-Control system.
Every user and every fitter must know these safety mechanisms.
WARNING
Deactivated safety mechanisms
Serious bodily injury or material damage
The field sprayer manufacturers and fitters have the option of deactivating some safety mechanisms
so that the system can satisfy the special requirements of the field sprayer. Müller-Elektronik cannot
say which changes to the configuration a field sprayer manufacturer or a fitter carry out. Regarding
the deactivation of safety mechanisms, the person and the manufacturer that deactivate the
systems bear sole responsibility for this.
◦
Find out whether the field sprayer manufacturer or fitter has deactivated safety mechanisms.
The system is deactivated in the following cases:
▪
When the maximum permitted speed has been reached. By default the maximum speed is 15
km/h.
▪
When the user starts the DISTANCE-Control calibration. During the calibration the boom will be
controlled automatically in some phases.
▪
When an alarm message connected with DISTANCE-Control appears on the screen.
▪
When one of the following sensors sends a signal to the job computer:
– Boom locking sensor
– Lifting tower sensor
– Position sensor "Boom folded in"
Mode of operation
DISTANCE-Control is a system that automatically measures and regulates the height of the boom
above the subsurface and the slope of the boom.
For this purpose, the subsurface may be:
▪
Plants – when the DISTANCE-Control USonic sensors are positioned above plants.
▪
Ground – when the DISTANCE-Control USonic sensors are positioned above the ground.
On each side of the boom there is a Usonic sensor. The Usonic sensors constantly measure the
distance to the subsurface. Additional sensors measure the boom slope.
Thanks to the use of the sensors, the job computer always knows how high the boom is and how
much it is sloped. So it can adjust the position of the boom automatically.
The following diagram shows how DISTANCE-Control adjusts the height of the boom:
