LFP Cubic
Error
The displayed level value / SPx/
RPx / FHx/FLx / QALOW/QAHIGH
is greater than the probe length
Level occasionally jumps to a
higher value
Level occasionally jumps to 0 mm TrsHld set too high
No measurement of low levels for
media with low DKs
Increased measurement inaccu-
racy

The LFP uses IO-Link technology, which can be used in networks. SICK assumes that the integrity and
the confidentiality of the data and rights which are affected by the use of this technology are ensured
by the customer. In all cases, appropriate security measures, such as network separation, firewalls,
virus protection or patch management, must be taken by the customer on the basis of the situation in
question.

Cause
An offset was configured for the
level value
Incorrect probe length configured
Contamination in the vicinity of
the process connection
Spray ball or feed dampen probe
with medium above the medium
surface
Change in the ambient conditions
regarding the situation during the
AutCal process
Significant buildup of foam
TrsHld set too low, the echo
algorithm detects interference
reflections
Significant buildup of foam
Increased inactive range at the
probe end for media with a low
DK
Use of foam algorithm
Operating instructions
Solution
Adjust offset
(See Chapter 5.10 "Setting the
offset")
Adjust probe length (see Chapter
5.4 "Configuring the probe
length")
Clean
Observe the installation condi-
tions
Configure the MaxCoL plausibility
filter
(see chapter "5.2 Filtering mea-
sured values")
Perform commissioning again
(see Chapter 2 "Commissioning
the LFP")
Perform foam commissioning
(see Chapter 2.3 "Foam commis-
sioning")
Increase TrsHld
Perform advanced commissioning
(see Chapter 2 "Commissioning
the LFP")
Perform foam commissioning
