Error Message Description Category Remedy
NOT LINEARIZED Linearization faulty or
not activated =
measuring error
Maintenance Activate linearization or carry it out again
(HART
® communication and linearization
software are required; the original
calibration values must be known), or send
the device back to the manufacturer for
linearization.
NEW LINEARI.
TABLE BAD
Faulty or missing
data in the
linearization table =
measuring error
Warning
LINEARIZATIO
UNDER CONFIG
The device is in
linearization mode =
measuring error
Warning Complete the linearization and activate it
(HART
® communication and linearization
software are required), or send the device
back to the manufacturer for linearization.
UNIT SYSTEM
CONFLICT
The unit for the
linearization flow is
incompatible with the
selected flow type
(mass/volume)
Warning Correct error, carry out linearization again if
necessary (HART
® communication and
linearization software are required), or send
the device back to the manufacturer for
linearization.
TOO FEW
ENTRIES
The linearization
table has too few data
points
Warning Carry out linearization at at least 5 points
(HART
® communication and linearization
software are required), or send the device
back to the manufacturer for linearization.
NOT
MONOTONOUS
The sequence of the
linearization values is
not strictly monotonic
increasing
Warning Check linearization and/or carry it out again
(HART
® communication and linearization
software are required), or send the device
back to the manufacturer for linearization.
FIRST NOT 0 % The first flow value if
the linearization table
is not 0%
LAST NOT 100 % The last flow value if
the linearization table
is not 100%
NO ZERO CAL
OF AO
The current output
zero point 4.00mA is
not calibrated. =
possible measuring
error in process
control.
Maintenance Perform calibration using ammeter and
menu 3.10 or using standard HART
®
tools/process control system and poss.
external ammeter. Caution: during
calibration, switch the measuring point to
manual control.
NO F.SC. CAL
OF AO
The current output
100% = 20.00mA is
not calibrated. =
possible measuring
error in process
control.
Maintenance Perform calibration using ammeter and
menu item 3.11 or using standard HART
®
tools and external ammeter if necessary.
Caution: during calibration, switch the
measuring point to manual control.
NO TEMP.
COMPENSATION
The sensor
temperature
compensation of the
device is faulty or was
not carried out. =
possible measuring
error
Maintenance The device, together with an indication of the
error, must be sent back to the
manufacturer for checking.
OUTPUT NOT
LINEARIZED
Linearization is not
activated = measuring
error
Maintenance Activate linearization or carry it out again
(HART
® communication and linearization
software are required; the original
calibration values must be known), or send
the device back to the manufacturer for
linearization.
COUNTER LOST Totalizer value was
reset by
error/overflow
Warning Because the reset time is not known:
Controlled reset of the counter using menu
item 1.6.1 or using HART
® tools/process
control system.
