The following table lists the messages that can occur. The Diagnostic code/
ACTUAL_HIGHEST_ALARM parameter displays the message with the highest priority. The
device has four different status information codes according to NE107:
• F = failure
• M (warning) = maintenance required
• C (warning) = function check
• S (warning) = out of specification (deviations from the permitted ambient or process
conditions determined by the device with the self-monitoring function, or errors in the
device itself indicate that the measuring uncertainty is greater than what would be
expected under normal operating conditions).
Message display:
•Local operation:
– The measured value display shows the message with the highest priority.
– The Diagnostic code/ACTUAL_HIGHEST_ALARM parameter displays all messages
present in descending order of priority. You can scroll through all the messages pending
using the S or O key.
• FieldCare:
The Diagnostic code/ACTUAL_HIGHEST_ALARM parameter displays the message with
the highest priority.
See the "Priority" column.
• Diagnostic Transducer Block (FF configuration program):
The Diagnostic code/ACTUAL_HIGHEST_ALARM parameter displays the message with
the highest priority. Every message is also output as per the FOUNDATION Fieldbus
Specification by means of the Transducer error/XD_ERROR and Block error/
BLOCK_ERROR parameters.
Numbers are given for these parameters in the following table which are explained
 ä 224.
• You can view a list of the active alarms via the Diagnostic code/
ACTUAL_HIGHEST_ALARM parameter.
• You can view a list of alarms which are no longer active (event log) via the Last diag. code/
LAST_ALARM_INFOS parameter.

C484 Error simul. 17 0 – Fault state simulation is switched on, i.e.
the device is not measuring at present.
End the simulation
C485 Measure simul. 17 0 – Simulation is switched on, i.e. the device
is not measuring at present.
End the simulation
C824 Process pressure 20 8 – Overpressure or low pressure present.
– Electromagnetic effects are greater than
specifications in the technical data. This
message normally only appears briefly.
1. Check the pressure value
2. Restart the device
3. Perform a reset
F002 Sens. unknown 20 8 – Sensor does not suit the device
(electronic sensor nameplate).
Contact Endress+Hauser Service
F062 Sensor conn. 20 8 – Cable connection between sensor and
main electronics disconnected.
– Sensor defect.
– Electromagnetic effects are greater than
specifications in the technical data.
1. Check sensor cable
2. Replace electr.
3. Contact Endress+Hauser Service
4. Replace sensor (snap-on
