Monitoring of the
distances using tested SAC
function.
The analogue distance
measured values are
compared mutually for
max. tolerance (analogue
sensor diagnostics)
Monitored for minimum
values (SAC function)

encoder
1 x incremental
encoder on
motor / drive
wheel
Muting of the diagnostics
for both running gear
sensors using tested SCA
function
Muting is started before
each gap, an incorrect
encoder value is then
briefly suppressed.
In the gap an encoder
value outside of 2 to
160000 mm results in
muting
