Diagnostic messages

The controller (or indicator) is programmed to display diagnostic messages that provide information on servicing requirements and
any other conditions that develop during operation.
When a diagnostic condition is detected, the associated NAMUR icon, plus the highest priority diagnostic message, is displayed in
the Status Bar when in Operator View. A list of all currently active diagnostic alarm states are displayed in the Diagnostic View.
