Alarms and Trips
This section lists the available user-notification
codes of the EOI display and provides information
that assists the user in the event that a Fault is
incurred. The User Notification codes are displayed
as an indication that a system function or system
condition is active (i.e., ATN, DB, and DBON). The
code is displayed on the EOI for the duration of the
activation.
If a user setting or an ASD parameter has been
exceeded, or if a data transfer function produces an
unexpected result, a condition that is referred to as
a Fault is incurred.
An Alarm is an indication that a Fault is imminent if
existing operating conditions continue unchanged.
An Alarm may be associated with an output
terminal to notify the operator of the condition
remotely, close a contact, or engage a brake. At the
least, an Alarm will cause an alarm code to appear
on the EOI display.

feature that disables the ASD system in the event
