ATLAS 800 Series System Manual System Status Menu Descriptions
System Alarms (ATLAS 890)
System Alarms (ATLAS 890)
Displays the status of all ATLAS 890 system alarms. The following symbols are used.
Power Indicates that one or both of the power supplies are not functional. These power
supplies are continuously monitored to determine failures. If one of these
supplies fails, a message will be placed in the E
VENT LOG (see System Event
Log on page 353 for more details).
Temperature Indicates that the internal temperature of the power supply has exceeded normal
operating limits. When the operating temperature is exceeded by any power
supply, a warning will be placed in the
EVENT LOG but no other action will be
taken (see System Event Log on page 353 for more details).
Fans Indicates that installed fans are operating normally.
External Input Indicates that the external input has been activated. [–] indicates that input is not
active and
[*] indicates that input is active.
System Timing Source
Read security: 5
Indicates which timing source (primary or backup) is in use by ATLAS and whether the system is locked
onto this source. If the display does not indicate locked, the ATLAS does not have a valid source of timing
and cannot reliably transfer data. Review the current setting for system timing source in the
SYSTEM
C
ONFIG menu. See Primary Timing Source on page 83 and Backup Timing Source on page 83 for details.
Resource Usage
Write security: 5; Read security: 5
Provides resource usage tracking for dynamic resources throughout the system. This includes current,
average, and minimum availability for both analog and digital resources.
