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
Replace process feedtrough
Check HF connector, replace cable
if defective
Check temperature, replace HF
module if defective
wait some seconds until alarm
disappears
