8 LOCAL USER INTERFACE
If [3/N] (NO) is entered followed by [ENT] key, protection is not enabled and the status LED remains RED. The
ACT command menu is displayed with the cursor positioned on the item Dig output test.
The test may be stopped by pressing the [END] [ENT] key sequence, ending the relay session with protection
turned ON.
The available digital output tests and their corresponding numbers are listed below.

This category checks the relay logic and outputs by replaying oscillography data. The oscillography data can
be the embedded factory test case, uploaded oscillography data, or oscillography data stored in the relay.
After this command is selected, the following message appears (if protection is currently disabled):
The cursor is positioned at the beginning of the third line. If the user responds NO, CANCELED is displayed
and the test is canceled. If the user presses any keys other than [1/Y] or [3/N] and presses the [ENT] key, an
error message is displayed. It can be cleared and a valid input can be entered using the [CLR] key.
If the user responds YES, protection is enabled and the relay asks whether to disable the outputs, if they are
currently enabled. The user presses [1/Y] or [3/N] followed by [ENT] key. These keys are echoed on the display
as YES or NO respectively. If [1/Y] is pressed, the outputs are disabled and then the playback mode is contin-
ued. The outputs can be enabled after the playback is complete. If [3/N] is pressed, the outputs remain
enabled. Any control actions issued by the relay take place in this case.
If the outputs are disabled, the status LED turns RED since the relay is currently not protecting the line. If they
remain enabled during playback, the status LED turns RED only for the duration of the playback. In that case,
after the playback is complete, the status LED turns GREEN again.
The cursor will be located on the second line. The option Factory test case is chosen by moving the cursor to
that line and pressing the [ENT] key.
The user is prompted to select the settings which used during playback. If [1/Y] is pressed followed by [ENT]
key, the relay settings currently in effect will be used during playback. If [2] is pressed followed by [ENT], the
settings stored with the oscillography data will be used.
