is an indication that there is a system operating limit that is being exceeded and that a
Fault
may be imminent (not all ongoing alarms result in a fault) or to provide an indication that an operator error
has occurred. An
Alarm
may be associated with an output terminal to notify the operator of the condition
remotely, close a contact, or to engage a brake. At the least, an
Alarm

on the EOI display
The active alarm may be displayed on the

key if the alarm is displayed on the
