Diagnostics and troubleshooting

9.1 Basic troubleshooting
Initial checking of the application
The first step in determining the health of the installation and/or application is to observe the
lower line of the HMI display, which indicates when an active alarm is present (as shown in the
example below).
Figure 9-1 HMI display with alarm indication
Scrolling up or down to display View 6 will show all active alarms. See Device status icons
(Page 100) for details regarding the specific status icons and alarm codes. A more detailed
explanation and suggested action for the individual alarm code can be seen by pressing the
right arrow while in display view 6.
Note
In cases where the end user has "disabled" view 6, the active alarms can be viewed in
the Diagnostic events Active diagnostic events menu.

Note that the alarms will persist even after the problem is resolved, unless the Diagnostic
events Acknowledge mode is set to Auto, or the alarm is manually acknowledged.
Maintenance alarms:
Depending on the type and severity of a maintenance alarm, the flow measurement may be
either completely stopped or the accuracy of the flow measurement degraded. Maintenance
alarms are also triggered by system related diagnostics, such as system monitoring, PCB
temperature, memory, communication problems, etc.
