On the other hand, if the display module is correctly configured and assigned, it displays
dashes if no assigned detector or AM is in alarm condition; otherwise it displays the status
and the main features of the field devices in alarm condition.
Normally, if several alarms are present, the display module brings up the scan of
alarms in order of importance (2t, 1t, Pr). An alarm, or a variation of one already
present (for example moving from 1t to 2t), takes priority on the display until normal
scanning starts again.
If there are problems on the communication line, or an internal fail that prevent information
exchange with the control unit, the display module brings up the following message:
If the control unit is configured with the dedicated WINDOWS application, the display
module shows the identification string of the field device in alarm condition on the top line
(Fig. 6.48), alternated with the alarm page as shown in Fig. 6.46.
