ALARM CHANGE INDICATION
The time and date of the last alarm state change is shown in the
Alarms
menu on Web page and Display. The
last alarm change is also shown on the display Home page.
ALARM GROUPING
EC500 has provision for grouping of individual alarms. A maximum of 64 alarm groups can be configured. The
user can map individual alarm to up to two alarm groups. Grouping provides an OR function. User can edit
group names to match the requirement. Some of the group names may not be editable. Only Groups can be
mapped to operate output relays. Alarms cannot be mapped directly to relays. In case alarm grouping is not
required, users can map individual alarms to independent group.
If a Potential Free alarm output is required, the alarm should be mapped to at least one
alarm group.
