9.8.2.1.1. Level sensor calibration screen
The offset values for the level sensor
are displayed here. These values must
be entered into the system first, before
the calibration is started.
4211 – Level probes

Entry of compartment-specific
parameters for each compartment:
1. Entry of ice protection offset:
always 25 mm
-> ice protection offset = ice protection
height
2. Entry of float offset from the pre-acceptance test certificate
-> float offset = depth of immersion of float
3. Entry of level sensor zero point. Enter the raw value for the level sensor
from the Diagnosis menu or enter it automatically with the aid of the <F2> key =
‘zeroing’ function.
4. Float MAX: Fill height, up to which the compartment is to be filled at the
start of the calibration. (Determine by measurement or by trial and error when
loading!).
Keys <F1> = ← and F3> = → are used to change to the other compartments.
The adjacent diagram shows how the height parameters are structured in the
system. The ‘zeroing’ of the level sensor means that the measured height value is
entered automatically into the system as the ‘Level sensor zero point’, i.e. H
0meas
.
The fill height is then calculated using the following equation:
H = H
roh
– H
0mess
+ H
o
+ T
In the case of service, the level sensor can be exchanged without having to
perform calibration trials once again.
