Chapter 8 – Diagnostics
Each alarm has an associated description string. The string will include a port
number if it is relevant. The description may also provide an indication of the
recent rate at which this alarm is occurring (if the alarm has occurred previously).
Alarms And The Critical Failure Relay
All active alarms will immediately de-energize the critical fail relay (thus signifying
a problem). The relay will be re-energized when the last outstanding active alarm
is cleared.
Viewing And Clearing Alarms
Viewing Alarms
The Alarms Menu is available from the Diagnostics menu View Alarms command.
Alarms are displayed in the order in which they occurred, even if the real time
clock was incorrect at the time of the alarm.
