14.5.1 Alert history and log
The transmitter automatically saves information about all alert occurrences to its working memory, and
periodically updates an alert history file on its SD card. The alert history log is an ASCII file.
Contents of alert history
The alert history in the transmitter's working memory contains the 1000 most recent alert records. Each alert
record contains the following information:
• Name of alert or condition
• Category:
— F=Failure
— FC=Function Check
— M=Maintenance Required
— OOS=Out of Specification
— I=Ignore
• Action:
— Active=Transition from inactive to active
— Inactive=Transition from active to inactive
— Toggling=More than 2 transitions in the last 60 seconds
• Timestamp
— Format: Military time
— Time and time zone: Transmitter clock
— Not displayed if Action=Toggling
Alert history and power-cycles
If the transmitter is rebooted or power-cycled, the 20 most recent records in alert history are retained in the
transmitter's working memory. All earlier records are cleared from working memory. The alert history file on
the SD card is not cleared.
Alert history and configuration files
If you restore the factory configuration or upload a configuration file, alert history is not affected.
