Alarms
An Alarm is an indication that a Fault is imminent if existing operating conditions continue unchanged.
Table 13
lists the alarm codes that may be displayed during operation of the WX9 ASD. Each alarm code
listed is accompanied by a description and a possible cause. In the event that the source of the malfunction
cannot be determined, contact the TIC Customer Support Center for more information on the condition
and an appropriate course of action.
During an active Alarm, the display toggles to and from the running frequency and the active Alarm. In
the case of multiple Alarms, only the first to be detected will be displayed on the Frequency Command
screen.
Note:
Some User Notification conditions and Alarms may be annunciated via a discrete
output terminal setting. See
conditions that may be associated with an output terminal.
