Applies the setting and returns to the main menu.
Cancels the setting and returns to the main menu.
Enables/disables the Backlight burnout detect
function.
(Default: ON )
When a burned-out backlight is detected, the
status LED flashes alternately green and red, or a
steady orange.
Touch-operation will be disabled when the
backlight burns out, which prevents the FP from
sending input signals to the PLC.
Normally, the FP unit detects a backlight
burnout by monitoring the backlight's
current flow, however, the FP may fail to
detect this condition, depending on the
type of backlight problem.
Enables/disables the screen display Auto OFF
function and sets the time when the Auto OFF
function is enabled.
(Default: OFF <Auto OFF function disabled>)
The Auto OFF function automatically turns off the
display to prevent the screen from burning out
when the touch panel is not used for some period
of time. With this parameter, you can set the time
interval to turn off the screen display (how much
time passes before the screen display is turned
off) when the touch panel is not used. If the touch
panel is not touched over the set time, the
backlight will automatically turns off.
Select the time period from 1 min, 3 min, 5 min,
10 min, and OFF (Auto OFF function disabled).
In this screen, touching the value displayed on the panel changes the value of
the time period.
If an analog RGB interface is used and the
horizontal display position exceeds the
normally adjustable range, setting the POLAR-
ITY LOCK feature to ON may allow you to
adjust the display position. (Default: OFF
<Disabled>)
This setting is enabled after the OSD is
closed.
