6.4 Error messages
Error message Description Category Remedy
NOT LINEARIZED Linearization faulty or
not activated =
measuring error
Errors 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 non-existent
data in the
linearisation table =
measuring error
Error Check 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 a check of the
linearization.
NOT
MONOTONOUS
The sequence of the
linearisation values
does not rise
monotonously.
Error 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 level value of
the linearisation table
is not 0%
LAST NOT 100 % The last level value of
the linearisation table
is not 100%
LINEARIZATIO
UNDER CONFIG
The device is in
linearization mode =
measuring error
Error 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 of the
linearisation value is
not correct for the
select level meter.
Error 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 linearisation
table does not have
enough support
points.
Error 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.
NO ZERO CAL OF
AO
The analog output
zero point 4.00 mA is
not calibrated. =
Possible
measurement error
in the process control
system
Warning 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. =
potential measuring
error in process
control
Warning 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 has
not been carried out =
possible measuring
error
Error 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
Error 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.
