Measurements out of specification
Simulation of the measured values
F backup 1 settings
Error during the CRC check of the backup 1
or 2 settings.
Save active settings in backup 1 or 2.
F backup 2 settings
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 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. Counter has overrun and
started again at zero.
-
S overflow counter 2
This is counter 2. 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; refer to 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.
-
Messages on the display Description
Actions
Status: F _ _ _ _ _
Application-dependent fault, device OK,
but measured values affected.
Application test or operator action
necessary.
