8.2.5 Control window
This menu item is only then displayed when a grade sensor is
active.
Erratic amendments in the measured value of a sensor can
occur due to various reasons. Causes can be both negligence
of the operating personnel (obstacles in the sound beam of an
ultrasonic sensor, crossing over a string line holder etc.) as well
as technical errors (reference string is torn, etc.).
To prevent these unintended measurement errors and the
resulting extreme controlling actions of the machine, the
measured values of all grade sensors can be allocated with a
so-called
“control window”.
If a control deviation occurs which is greater tha n the range set
here, then this deviation will be detected as an error.
In this case a warning symbol
“Measured value is outside the
control window
” will appear in the display, the complete LED
arrow flashes and the activation of the hydraulic cylinder wil l be
switched off.
