Transmitter operation
Procedure
• To view the current status of all possible alarms, select ProLink→Status . To view status indicators in
an alarm category, click on one of three tabs in the Status window: Critical , Informational , or Operational .
The Status window displays the current status of all possible alarms, including Ignore alarms on the
three panels. A tab is red if one or more status indicators in that category is “on.”
• A green LED indicates an Inactive alarm.
• A red status indicator indicates an Active alarm.
• To view and acknowledge active and inactive Fault and Information alarms, select ProLink→Alarm Log .
To acknowledge an alarm, check the ACK check box.
The transmitter automatically filters out Ignore alarms. Entries in the alarm log are divided into two
categories: High priority and Low priority. These priorities correspond to the default severity levels
for the type of alarm. Within each category:
• A red LED indicates an Active alarm.
• A green LED indicates an Inactive alarm that has not been acknowledged.

Procedure
• Press Service Tools→Alerts to view the active Fault and Informational alarms. The transmitter
automatically filters out Ignore alarms.
• Press Service Tools→Alerts→Refresh Alerts to refresh the view of the active alarms.
• Press Service Tools→Alerts , and select the individual alarm to view and acknowledge the alarm.
8.4.4 Interaction of transmitter fault actions and
Alarm Severity
level
When an alarm condition occurs, the transmitter responds by reporting a status alarm. Each status
alarm has an alarm. Alarms are classified into three severity levels:
Fault , Information , and Ignore . Severity
level controls how the transmitter responds to the alarm condition. You can change the Alarm Severity
for some 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 .
When the transmitter detects an alarm condition, the following occurs:
• An alarm is posted for the corresponding alarm:
− First status flag is set to Active .
− Second status flag is set to Unacknowledged .
• The transmitter checks the severity level for the specific alarm:
− If Severity is Fault , outputs go to their configured Fault Action (after the configured fault timeout
has expired).
− If the Severity is Information or Ignore , outputs are not affected. They continue to report process
data.
