Control window
This menu item is only shown when a distance sensor is currently
selected as the active sensor, as it only has an effect on this sensor
type.
Transient changes in a sensor's measured value may occur due to
diverse reasons. Causes may include both inattentiveness on the part
of the operating personnel (obstacles in an ultrasonic sensor's sound
beam, driving over a cable bracket, etc.) and technical faults (reference
cable torn, etc.).
To avoid these undesired measuring errors and the vehicle's resulting,
extreme control actions, the measured values of all distance sensors
can be placed into a so-called "control window".
If a control variance which occurs is greater than the range set here,
this variance is recognised as an error.
In this case, the warning symbol "Measured value outside of control
window" appears on the display, the entire LED arrow flashes and
hydraulic cylinder actuation is shut-off.
