Front-Panel Interface
Pushbuttons
When you select the {GROUP} button, the relay display shows
Active Group 1
(for example), and asks whether you wish to
Change
or
Exit
. Use the right/left
arrow keys and
{SELECT}
to choose.
If
Change
is selected, the display shows
Change to Group
in the first line, and
the present group number in the second line. Use the up/down arrows and
{SELECT}
to choose another group. The relay will ask for a
Yes/No
verification
of the change. Use the right/left arrow keys and
{SELECT}
to choose. The
change will be made and the ALARM contact pulsed for one second if
Yes
is
chosen, and if SS1 through SS6 are not asserted or not assigned . These
group selection settings always take precedence over the GROUP command
function.
{CANCEL} may be used to return to an earlier menu. {EXIT} will abort the
command and return to the default display.
Secondary Function
Review
The secondary button functions come into effect as soon as one of the buttons
for the above primary functions has been pushed. These secondary functions
remain in effect until a primary function has been completed, aborted, or
exited and the display has returned to the default 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}
pushbutton returns the display to the previous menu within a
primary function. Use the {CANCEL} pushbutton to go back after issuing a
{SELECT} . If there is no previous menu, the default display is shown. If the
{CANCEL}
pushbutton is pushed while the relay is in the default display mode,
the relay interprets the button as the
{METER}
pushbutton.
SELECT
The
{SELECT}
pushbutton is used within primary function dialogues to select a
menu choice. Once the choice has been identified with the arrow buttons, use
the
{SELECT} pushbutton to select that choice. If the {SELECT} pushbutton is
pushed while the relay is in the default display mode, the relay interprets the
button as the
{EVENTS}
pushbutton.
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 the relay is 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}
pushbutton at any time within one of the dialogues, the
procedure is aborted and the display reverts to the default display. If the
{EXIT}
pushbutton is pushed while the relay is in the default display mode, the relay
interprets the button as the
{GROUP} pushbutton.
