TAR
This command is roughly equivalent to the
TAR F
serial port command. When TAR is selected
in the OTHER main menu, the display shows
TAR 0
, the first row of the Relay Word bits, with
EN
shown in the second row (relay enabled). The up/down arrow keys may be used to scroll
through the remaining rows of the Relay Word bits. For these rows, the asserted Relay Word bit
names will be listed in the second row of the display, and the corresponding LED positions will
be lit in the target area above the display. If more bits are asserted than will fit in the display, the
right/left arrow keys may be used to see the off-screen names.
Push
<CANCEL>
to return to the OTHER main menu. Push
<EXIT>
to return to the default
display.
TIME
This command works like the
DATE
command above and is equivalent to the
TIME
serial port
command.
When selected, a two-line display appears, with the current time on the first line and a prompt to
Set
or
Cancel
on the second. Use the right/left arrows and
<SELECT>
to choose. Because this
is a Level 1 command, it is not password protected from the front panel. If Set is selected, a
second display appears, prompting the user to change the time. Use the right/left arrows to move
between the HH:MM:SS fields, and the up/down arrows to scroll to the number selected for the
field. When the time is shown correctly, push
<SELECT>
to enter it. Push
<CANCEL>
to
return to the OTHER main menu. Push
<EXIT>
to return to the default display.
Note:
After setting the time, allow at least 60 seconds before powering down the relay or the
new setting may be lost.
SET
The SET function has the most elaborate menu and display structure of all the pushbutton
functions. Only numeric value settings, or settings having fixed character string values, can be
displayed or changed on the display. Settings that are SEL
OGIC
control equations cannot be
displayed or changed.
To show or set relay settings, press the
<SET>
button. There are four set/show options:
GROUP
,
GLOBAL
,
PORT,
and
PASS
. Use the right/left arrow keys and
<SELECT>
to
choose. These will be discussed in alphabetical order.
Figure 8.10, at the end of this section, shows the essential menu and display structure for the SET
button. It does not show anything below the setting section (subgroup) level, because this would
be too cumbersome.
GLOBAL
This command is roughly equivalent to the
SHO G
and
SET G
serial port commands. When
GLOBAL is selected, a menu appears for selecting whether to
Set
or
Show
the settings. If Set, a
password entry screen appears, if password protection is in force.
