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 Table 11, page 44. Refer to section 3.6.7,
page 27 for configuration information.
