7.6

Handling status alarms

Specific process or flowmeter conditions cause status alarms. Each status alarm has an alarm code.

Status alarms are classified into three severity levels: Fault, Information, and Ignore. Severity level
controls how the transmitter responds to the alarm condition.

Note: Some status alarms can be reclassified, i.e., configured for a different severity level. For
information on configuring severity level, see Section 8.8.

Note: For detailed information on a specific status alarm, including possible causes and
troubleshooting suggestions, see Table 11-2. Be
fore troubleshooting status alarms, first acknowledge
all alarms. This will remove inactive alarms from the list so that you can focus troubleshooting efforts
on active alarms.

The transmitter maintains two status flags for each alarm:

The first status flag indicates “active” or “inactive.”

The second status flag indicates “acknowledged” or “unacknowledged.”
