ABB DSQC639 3HAC025097-001 Configuring Process Power

Description

Alarms are also indicated on all displays as a latest unacknowledged alarm line, and as red
status indications in displays with dynamic data from the objects concerned, flashing until the
alarm is acknowledged, and then steady as long as the alarm condition persists.
You can also configure objects for repetition control of alarms, which means that repetitive
reporting of the same alarm is suppressed if the object toggles between the normal and faulty
states. On your request, the alarm and event messages can be presented in different types of
lists. The lists can be presented as base displays or as overlap displays. When presented as base
displays the lists can be directed to another screen by using the dedicated screen function.

Thefollowing types of lists are available:
• Process event lists
• Process alarm lists
• System alarm lists
The system alarm lists contains messages of control system errors, indicating faults or other
changes of state in the control system. All three types of lists can be printed on request, when
the events and alarms occur. The length of the lists, for example, the number of alarms in the
process alarm list can be configured.
