6.5.2 How to Display the Alarm List
You will find the Alarm list indication under the Monitoring function. This Alarm List indication will display all active
alarms on the top line of the LCD.
Follow the instructions below.
The display indication XX shows you how many alarms are in the alarm list. The list shows Active alarms and Non-
acknowledged (Reset) alarms based on the alarm configuration. If a “LCD Latch” function is selected for an alarm,
it will remain in the alarm list even if the alarm condition has disappeared. In this case, a manual alarm reset will
clear it from the alarm list.
Select ‘View’.
The alarm is shown in clear text on the top line. Pressing ‘Next’ will show you the next alarm in the list and pressing
‘Back’ will show you the previous alarm in the list.
If an alarm has not been acknowledged the text 'Reset' will flash. If the alarm is acknowledged and the alarm option
“LCD latch” was activated (see Alarm Setup for details), the alarm will be removed from the list provided the
condition of the alarm has been cleared.
If an alarm is associated with a signalling relay with latching, the display of this alarm is imperatively "latch" set.
The acknowledgment of the alarm using the display causes the acknowledgment of the associated relay too.
