4.7.14 DataCORDER Alarms
The 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 values to the DataCORDER, an alarm is generated. The Data-
CORDER contains a buffer of up to eight alarms. A listing of the DataCORDER alarms is provided in
Table 4–10 ,
page. Refer to Section 4.7.7 for configuration information.

b. To scroll to the end of the alarm list, press the UP ARROW. 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

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.
