Monitoring Status/Alarm Conditions _____________________
The Receiver is at all times monitoring various operating conditions through a
status/alarm reporting system. The Receiver is shipped from the factory with
the status system set to generate an alarm under a default set of operating
conditions.
The monitored operating conditions are organized by function into three major
groups: Questionable status, Command Error status, and Operation status.
The Operation status group has three functional subgroups: Powerup status,
Holdover status, and Hardware status.
All of the operating conditions are summarized by the Alarm status.
Figure 5-1, on the next page, includes the identification of the default alarm
conditions. Those conditions which are enabled to “feed” all the way through
the system will generate an alarm in a Receiver configured with the factory
defaults. (Note a diagram identical to Figure 5-1 is provides as part of the
Receiver Commands at a Glance (cont’d)/Status Reporting System at a Glance
foldout—pages 4-17 and 4-18, respectively.)
