Alarm
An Alarm 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 will cause an alarm code to appear
on the EOI display
The active alarm may be displayed on the Alarm screen — some alarms are displayed on the Frequency
Command screen. Press the Mode key if the alarm is displayed on the Frequency Command screen to
