The event log is very useful for diagnosing fault conditions.
The
kind of information
which is included in the event log may be chosen by the user, by
selecting the Alarm
Actions
on the
Alarm page
, described in the section below.
Clearing the Event Log
The event log can be cleared by moving the cursor to the position on the screen where the
first event is shown (after 'Events :') and pressing <CTRL> and 'R' together. This will
delete all events
from the list, and leave the message 'Event Log Cleared' as the only event.
It may be useful to clear the
remote
event log at the same time, by accessing the REMOTE
page, and repeating this process.
System Alarms & Alarm port
Two general purpose relay contact pairs are provided for use with the Echo. Separate
changeover contacts are provided, for both MAJOR and Minor Alarms. The contacts may be
connected to external low voltage (SELV) equipment to give an alarm / network management
indication as required. These connections are shown in Appendix J.
