Rotating Default Display
In the preceding example, only two display points (DP2 and DP4) and their
corresponding display point labels are set. If additional display points and
corresponding display point labels are set, the additional enabled display point
labels join the rotation (display time = SCROLD) on the front-panel display.
The SCROLD setting is made with the SET G command and reviewed with
the SHO G command.
Display point label settings are set with the SET T command or viewed with
the SHO T command via the serial port (see Section 9: Setting the Relay and
SHO Command (Show/View Settings) on page 10.25).
For more detailed information on the logic behind the rotating default display,
see Rotating Default Display (Only on Models With LCD) on page 7.36.
Scroll Lock Control
of Front Panel LCD
The rotating default display can be locked on a single screen. (See Rotating
Default Display (Only on Models With LCD)). Access the scroll lock control
with the {OTHER} pushbutton.
Select
LCD for Scroll Lock Control mode. The rotating display will then
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.
Stop Scrolling (Lock)
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, or on
the current-meter display screen. While rotation is stopped, the active display
is updated continuously so that current or 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 LCD and resumes the rotating display.
Single Step
From the Scroll Locked state, single-step through the display screens, by
pressing the {SELECT} key twice. Wait for the first press to 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.
