DataCORDER Alarms

Alarm display is an independent DataCORDER function. If an operating parameter is outside of the expected
range or a component does not return the correct signals back to the DataCORDER an alarm is generated. The
DataCORDER contains a buffer of up to eight alarms. A listing of the DataCORDER alarms is provided in
10. Refer to Section 4.6.7
To display alarm codes:
a. While in the Default Display mode, press the ALT. MODE & ALARM LIST keys. This accesses the Data
CORDER Alarm List Display Mode, which displays any alarms stored in the Alarm Queue.
b. To scroll to the end of the alarm list press the UP AR ROW. Depressing the DOWN ARROW key will scroll
the list backward.
c. The left display will show "AL#" where # is the alarms number in the queue. The right display will show
"AA##," if the alarm is active, where ## is the alarm number. "IA##," will show if the alarm is inactive.
d. "END" is displayed to indicate the end of the alarm list if any alarms are active. "CLEAr" is displayed if all the
alarms in the list are inactive.
e. If no alarms are active, the Alarm Queue may be cleared. The exception to this rule is the DataCORDER
Alarm Queue Full alarm (AL91), which does not have to be inactive in order to clear the alarm list. To Clear
the Alarm List:
1. Press the ALT. MODE & ALARM LIST keys.
2. Press the UP/DOWN ARROW key until "CLEAr" is displayed.
3. Press the ENTER key. The alarm list will clear and "-----" will be displayed.
4. Press the ALARM LIST key. "AL" will show on the left display and "-----" on the right display when there
are no alarms in the list.
5. Upon clearing of the Alarm Queue, the Alarm light will be turned off.
