Measurements out of specification
Simulation of the measured values
F factory settings Error during the CRC check of the factory
settings.
-
F backup 1 settings Error during the CRC check of the backup 1
or 2 settings.
Save active settings in backup 1 or 2.

Messages on the display Description Actions
Status: S _ _ _ _ _ Out of specification, measurement
continues, accuracy possibly less. Maintenance required.
S uncertain measurement Device maintenance necessary; measured
values only conditionally usable.
Group message, when errors as described
below or other influences occur.
S empty pipe 1 or 2 measuring electrodes are not in
contact with the medium; measured value is
set to zero. No measurement possible.
Measuring pipe not filled, function
dependent on Fct. C1.3.2. Check
installation. Or electrodes completely
insulated e.g. by oil film. Clean!
S field coil broken Field coil resistance too high. Check field coil connections to the
electronic module (for remote versions:
field current cable) for open circuit / short
circuit
S field coil bridged Field coil resistance too low.
S electronic temperature Upper limit for the permissible electronic
temperature has been exceeded.
Ambient temperature too high, direct solar
radiation or, for C version, process
temperature too high.
S overflow counter 1 This is counter 1 or FB2 (with Profibus).
Counter has overrun and started again at
zero.
-
S overflow counter 2 This is counter 2 or FB3 (with Profibus).
Counter has overrun and started again at
zero.
-
S backplane invalid The data record on the backplane is invalid.
The CRC check has revealed a fault.
No data can be loaded from the backplane
when replacing electronics. Save the data to
the backplane again (Service).
S field frequency too high The field frequency is set so high that the
field current cannot settle. The measured
values displayed are too low.
Set field frequencey lower, see Fct. C1.1.13.
Messages on the display Description Actions
Status: C _ _ _ _ _ Output values partially simulated or
fixed Maintenance required.
C checks in progress Test mode of the device. Measured values
are possibly simulated values or values with
fixed settings.
Message depending on the situation via
HART
® or FDT.
C test sensor Test function of the measuring sensor
electronics is active.
-
C simulation fieldbus Values on the Foundation Fieldbus interface
are simulated.
-
Messages on the display Description Actions
Status: F _ _ _ _ _ Application-dependent fault, device OK,
but measured values affected. Application test or operator action
necessary.
