Operation Troubleshooting
Operating symptoms, probable causes, and resolutions.
Symptom Cause Action
display reads
level or target is out of range
• check specifications
• check parameters
display reads
material build-up on antenna
• clean
• re-locate IQ 300
display reads
location or aiming:
• poor installation
• flange not level
• standpipe not vertical
• check to ensure standpipe is
vertical
display reads
antenna malfunction:
• temperature too high
• physical damage
• excessive foam
• inspect
• use foam deflector or stilling
well
• relocate
• use a defoamer
Reading does not
change, but the
level does
IQ 300 processing wrong
echo, i.e. vessel wall, or
structural member
• re-locate IQ 300
• check standpipe for internal
burrs or welds
• increase blanking, P800
Measurement is
consistently off by a
constant amount
P006 not correct
P652 not correct
• Check distance from Flange
face to zero level (P006)
• Check offset value (P652) or
device tag
Screen blank
power error
• check nameplate rating
against voltage supply
• check power wiring or source
echo confidence weak
• refer to P805
• use foam deflector or stilling
well
liquid surface vortexed
• decrease measurement
response P003
• increase confidence
threshold P804
Reading erratic
material filling
• re-locate IQ 300
Reading response
slow
P003 setting
• increase response if possible
