Electronics
Fatal DM Error
Internal error.
Perform a hard reset. If the
message recurs, contact the
manufacturer.
Fatal CO Error
Internal error.
Fatal Converter Error
An electronics or hardware
failure has occurred.
Emergency Off active
The current output has
triggered a safety reaction
and is signaling a failure
current below 3.6 mA or
above 21 mA.
Follow the instructions of
the "Safety Manual".
Internal Comm. Error
Error in the internal bus
communication.
Perform a hard reset. If the
message recurs, contact the
manufacturer.
Inconsistent Parameters
Error in the internal bus
communication.
Check the parameters and
make sure that the set of
data is consistent. Additional
information on the error can
be called via HART
®
interface.
Sensor Comm. Error
Error in the internal bus
communication or hardware
failure.
Perform a hard reset. If the
message recurs, contact the
manufacturer.
Power Supply Error
Internal voltage too low to
switch on sensor power
supply.
Check power supply
connection or replace the
electronics.
Sensor/Conv. FW Mismatch
Incompatible firmware
versions in the sensor and
the converter module.
Perform a hard reset. If the
message recurs, contact the
manufacturer.
Max. Number of Restarts
The device could not start
the measuring mode after a
cold starting.
Perform a hard reset once
again. If the message
recurs, contact the
manufacturer.
Converter Overvoltage
An electronics or hardware
failure has occurred.
Perform a hard reset. If the
message recurs, contact the
manufacturer.
Intern. Comm. Error
Error in the internal bus
communication.
Perform a hard reset. If the
message recurs, contact the
manufacturer.
F
Configuration
Voting Error
Same flow calculation on
redundant processors have
yielded different results.
Perform a hard reset. If the
message recurs, contact the
manufacturer.
Inconsistent NVRAM
Inconsistent data in the
parameter memory.
Error Starting SIL Mode
-
-
CO Float Error
Error in processing of the
measuring value due to
inconsistent set of
parameter.
Load the factory settings
and perform a hard reset.
If the message recurs,
contact the manufacturer.
Incons. Converter Calib.
