appear, and the scroll mode reminder screen will appear every eight seconds
for one second as a reminder that the display is in Scroll Lock Control mode.

When in the Scroll Lock Control mode, press the
{SELECT} key to stop display rotation. Scrolling can be stopped on any of the
display point screens. While rotation is stopped, the active display is updated
continuously so that the display point changes can be seen. If no button is
pressed for eight seconds, the reminder message will appear for one second
followed by the active screen.
Restart Scrolling (Unlock).
The
{SELECT}
key unlocks the modified
rotating display.

the next screen as the active display, then press the
{SELECT}
key a second time
to freeze scrolling.
Exit.
Press the {EXIT} key to leave Scroll Lock Control and return the
rotating display to normal operation.

clears all time accumulators of all the inverse-time overcurrent elements, both
for separate windings and for the combined overcurrent elements.

may be useful for saving time in testing the relay overcurrent elements but is
not likely to be used while the relay actually is in service.
If
RESET51
is selected, a password screen will appear if password protection is
in force. Next, a
Reset 51? Yes No
screen appears. Use the right/left arrows
to underscore
Yes
or
No
, then push
{SELECT}
.
Yes
will reset the accumulators
and exit the command.
No
will abort the command and return to the
OTHER
main menu; or, simply push {CANCEL} to return to the
OTHER
main menu. Push
{EXIT} to return to the default display.
