hardware problem
HF module or cable between HF
module and electronics defective
broken probe or value for probe
length is too short
broken probe detection is activated,
without carry out the mapping before
lost contact in the process
feedthrough
HF cable defective or HF connector
removed
temperature at the electronics too
high or HF module defective
mapping active
linearisation not monotonously
increasing
number of entered linearisation
points < 2
simulation mode is active
echo lost due to application
conditions of built up on antenna
noise on signal to high
level in safety distance
linearisation table is in edit mode
current out of range

Remedy
reset
avoid EMC problem;
2
PROM defect
if alarm prevails after reset, exchange electronics
wait some seconds; if warning prevails, exchange
electronics
wait until warning disappears
reset
avoid EMC problem;

PROM defect
if alarm prevails after reset, exchange electronics
reset
if alarm prevails after reset, exchange electronics
reset
if alarm prevails after reset, exchange electronics
reset
if alarm prevails after reset, exchange electronics
reset
if alarm prevails after reset, exchange electronics
restart download of data
contact service
wait some seconds; if warning prevails, power off
device and power on again
reset
avoid EMC problem;
2
PROM defect
if alarm prevails after reset, exchange electronics
reset
if alarm prevails after reset, exchange electronics
reset
if alarm prevails after reset, exchange electronics
check contacts on HF module
if fault cannot be eliminated: replace HF module
check the probe length in 033, check the probe
itself, if the probe is broken, change the probe, or
change to a non contact system
deactivate broken probe detection; carry out
mapping; activate broken probe detection
replace process feedtrough
check HF connector, replace cable if defective
check temperature, replace HF module if defective
wait some seconds until alarm disappears
correct linearisation table
correct linearisation table
switch off simulation mode
check installation; clean probe (see operating
instructions)
eliminate electromagnetic interference
alarm will disappear as soon as level leaves safety
distance
activate linearisation table
check calibration and linearisation
