The following table lists all the possible messages that can occur.
The device makes a distinction between the error types "Alarm", "Warning" and "Error". You may
specify whether the device should react as if for an "Alarm" or "Warning" for "Error" messages. See
"Message type/NA 64" column and → ä 46, "Response of outputs to errors".
In addition, the "Error type/NA 64" column classifies the messages in accordance with NAMUR
Recommendation NA 64:
• Break down: indicated with "B"
• Maintenance need: indicated with "C" (check request)
• Function check: indicated with "I" (in service)
Error message display on the onsite display:
• The measured value display shows the message with the highest priority. See the "Priority"
column.
• The ALARM STATUS parameter shows all the messages present in descending order of priority.
You can scroll through all the messages present with the S key or O key.
Message display via digital communication:
The ALARM STATUS parameter shows the message with the highest priority.
See the "Priority" column.
!
Note!
• If the device detects a defect in the onsite display during initialization, special error messages are
generated. For error messages, see → ä 45, "Onsite display error messages".
• For support and further information, please contact Endress+Hauser Service.
• See also "Repair", "Repair of Ex-certified devices" and "Spare Parts".
