Notes Settings
The Event Report Analog Quantities category is a freeform category in which
you can select as many as 20 analog quantities to report in the relay event reports.
By default, no analog quantities are configured.
The Event Reporting Digital Elements category is a freeform settings area in
which as many as 800 relay words from as many as 100 relay word bit rows may
be selected. See the product-specific instruction manual for the default configura-
tion. The 100 row limit includes the base set of Relay Word bits always included
in oscillography and event reports as described in Section 7: Metering, Monitor-
ing, and Reporting in the product-specific instruction manual.
Notes Settings
Avoid losing important information about the relay. Use the Notes settings like a
text pad to leave notes about the relay in the Notes area of the relay. Notes entries
are in a single block of 100 lines. By default, there is no text stored in the Notes set-
tings.
