Factory default values are supplied and can be restored after any changes.
The following communications settings are not transferred to the L90 with settings files:
Modbus Slave Address

The L90 takes itself out of service.
The L90 issues a UNIT NOT PROGRAMMED major self-test error.
The L90 closes the critical fail contact.
The Maintenance chapter outlines how to use a settings file in the .urs format for backup and restore.
4.1.3 Event viewing
While the interface is in either online or offline mode, you can view and analyze data generated by triggered parameters,
via one of the following:
Event recorder — The event recorder captures contextual data associated with the last 1024 events, listed in
chronological order from most recent to oldest
Oscillography — The oscillography waveform traces and digital states are used to provide a visual display of power
system and relay operation data captured during specific triggered events
Event records are viewable at the software and device-specific level. Access the former under Admin > Event Log > View.
Access the latter for a device under Actual Values > Records > Event Record.
Event record entries are explained in the next chapter for CyberSentry. The following table outlines some software-level
