Operation Troubleshooting
Operating symptoms, probable causes, and resolutions.
Symptom Cause Action
Display shows
S: 0 LOE
level or target is out of
range
• check specifications
• check Low Calibration Point (LOW
CALIB. PT.) (1.5.)
• increase Echo Confidence (2.2.3.6.1.)
Display shows
S: 0 LOE
material build-up on
antenna
• clean the antenna
• re-locate SITRANS LR260
Display shows
S: 0 LOE
location or aiming:
• poor installation
• flange not level
• check to ensure nozzle is vertical
•use Auto False Echo Suppression
(AUTO ECHO SUPP) (2.2.4.3.) and
check Auto Suppression Range
(AUTO SUPP RANGE) (2.2.4.4.) to
ensure nozzle protrudes from end of
vessel nozzle.
Display shows
S: 0 LOE
antenna malfunction:
• temperature too high
• physical damage
• check Maximum Internal
Temperature (MAX. INTERN. TEMP)
(3.3.8.)
• set Algorithm (2.2.3.1.1.) to tF
(trueFirst echo)
•relocate
Reading does not
change, but the level
does
SITRANS LR260 process-
ing wrong echo, i.e. vessel
wall, or structural member
• re-locate SITRANS LR260
• ensure nozzle protrudes 10 mm min.
• rotate instrument 90°
•use Auto False Echo Suppression
(AUTO ECHO SUPP) (2.2.4.3.) and
Auto Suppression Range (AUTO
SUPP RANGE) (2.2.4.4.)
Measurement is con-
sistently off by a con-
stant amount
• setting for Low
Calibration Pt. (LOW
CALIB. PT.) (2.2.1.3.) not
correct
• setting for Sensor Offset
( 2. 2.1.10. ) not correct
• check distance from sensor
reference point to Low Calibration
Pt. (LOW CALIB. PT.) (2.2.1.3.)
• check Sensor Offset (2.2.1.10.)
Screen blank
power error • check nameplate rating against
voltage supply
• check power wiring or source
