display. They will be discussed in the left to right order in which they appear on the front panel,
below the horizontal line. The first button, TARGET RESET / LAMP TEST, has no secondary
function except as a HELP key, explained earlier under the SET primary function.
CANCEL
The
<CANCEL>
button returns the display to the previous menu, within a primary function.
Use the
<CANCEL>
button to go back after issuing a
<SELECT>
. If there is no previous
menu, the default display is shown. If the
<CANCEL>
button is pushed while in the default
display mode, the relay interprets the button as the
<METER>
button.
SELECT
The
<SELECT>
button is used within primary function dialogues to select a menu choice. Once
the choice has been identified with the arrow buttons, use the
<SELECT>
button to select that
choice. If the
<SELECT>
button is pushed while in the default display mode, the relay
interprets the button as the
<EVENTS>
button.
Arrows
The arrow buttons are used throughout the front-panel primary function displays for scrolling
through lists of items, identifying menu choices by moving the cursor, and scrolling to the left or
right for more information. If one of the arrow buttons is pushed while in the default display
mode, the relay interprets the button according to the primary function. That is:
“left”
=
<STATUS>, “right”
=
<OTHER>, “up”
=
<SET>,
and
“down”
=
<CNTRL>
.
EXIT
If you push the
<EXIT>
button at any time within one of the dialogues, the procedure is aborted,
and the display reverts to the default display. If the
<EXIT>
button is pushed while in the
default display mode, the relay interprets the button as the
<GROUP>
button.

Table 8.3 summarizes the pushbutton functions and their approximate equivalents in serial port
commands.
