HART RESPONSE MESSAGES

ERROR AND WARNING MESSAGES

Four types of error and warning messages are generated
and displayed by the Hand Held Communicator:

- communication errors

- transmitter diagnostic messages
- database operations messages
- Hart Commands Response Code
The next paragraph gives a more detailed description of
the error and warning messages and the action that should
be taken.
COMMUNICATION ERRORS
XMTR NOT IN COMMUNICATION
timeout in communication, instrument not connected
Check that the connection is properly done, particularly
check if the resistance between the insertion point of the
Communicator and the power supply is 250 Ohm min. If
safety barriers are included in the loop check that they are
suitable for HART Communication.
If in direct mode check that only one transmitter is connected.
If in broadcast or multidrop mode check for tag duplication.
Try a connection closer to the transmitter terminals.
Check the Communicator with another transmitter to localize
the fault in the transmitter or in the Communicator.
Refer to your nearest Service Center.
WARNING : TX Rev. XX.YY TOO NEW
Indicates that the Smart Transmitter has a S/W Rev. level
newer than the S/W supported by the H.H. Communicator.
Contact your nearest Service Center for a S/W upgrade.
WARNING: TX NOT SUPPORTED
the transmitter connected to the KHT is unknown.
WARNING : FUNC. NOT SUPPORTED
the function that you are trying to execute with the KHT is
not available in the transmitter.
WARNING : OUTPUT CURRENT FIXED
The transmitter output is at fixed value (4 mA for Broadcast
connection or rarely any value for loop test not complete.
COMMUNICATION ERROR
Hand Held Terminal has detected an error on Checksum,
parity, etc. ( see XMTR not in communication )
ADDRESS ERROR
Answer received from an address different than the
requested ( usually in Multimaster Mode )
Mismatch in communication : repeat the command.
COMMAND ERROR
Answer received with a command number different than
the requested
Mismatch in communication : repeat the command.
CHECKSUM ERROR
The connected transmitter signals a communication
error: checksum not OK
The line appears noisy. Try a different point of connection
closer to the transmitter terminals.
- 44 -

PARITY ERROR

The connected transmitter signals a communication
error: parity not OK ( see Checksum error )
TRANSMITTER DIAGNOSTIC MESSAGES
ANALOG OUTPUT SATURATED
The process value is outside of the calibrated range of the
transmitter. Consider reranging the transmitter
PV OUT OF LIMITS
The process value is outside of the sensor limits. Consider
changing the transmitter or the sensor.
EEPROM 1 FAILED (pressure transmitters)
Fatal error: consider to replace the transducer. Refer to
the Transmitter Instruction manual.
EEPROM 1 FAILED (Deltapi K pressure Tx)
Refer to the Transmitter Instruction manual. Remove the
Compensation Module from the Electronics and clean,
with appropriate cleaning liquid, the contacts.
Try again and if still failing remove the electronics and
replace with a spare one fitting the compensation module:
if sstill failing the failure should regard the EEPROM
otherwise the electronics is faulty. 600T Transmitters
have not Compensation Module. Consider the replace of
the electronics.
EEPROM 2 FAILED (pressure transmitters)
Fatal error : the transmitter's electronics should be
replaced.
EEPROM 1 & 2 FAILED (pressure transmitters)
Fatal error : the transmitter's electronics should be replaced.
STARTUP CKSUM ERROR (pressure transmitters)
During the startup the transmitter's S/W found a check-
sum error. Try to restart the transmitter: if the error is still
present the transmitters should be replaced.
SENSOR FAILED (pressure transmitters)
The transmitter's sensor failed
SENS. TEMP. OUT OF LIM (pressure transmitters)
The sensor temperature is outside of the specification
limits: check in field if this appears true and then take
appropriate action to return within the limits . In case that
the temperature is within the limits the temperature
sensor or the sensor connection can be faulty: see the
transmitter's instruction manual for fault finding.
STAT PRES OUT OF LIM (pressure transmitters)
The static pressure is outside of the specification limits:
check in field and if true immediately disconnect the
transmitter from the process and consider to replacing
with another having appropriate rating.
In case that the pressure is within the limits the pressure
sensor or the sensor connections are suspect: see the
transmitter's instruction manual for fault finding.
