Appendix B: Display Screen and Device Setup Parameters
Display Screen Setup Parameters
The display screen Setup parameters affect the way in which the display
screen functions on your panel. These settings do not affect how
parameters are seen on other panels.
To access the display screen
Setup menu, follow these steps:
1. Press the Option button.
2. Rotate the control knob and select Setup .
3. Press the Enter button.
The display screen Setup parameters are described in the following
pages.
Scroll Mode
In Wrap mode, when you scroll through menus and non-numeric
parameters, the module considers the list as a circular set of data. When
the last parameter in the list is reached, the first parameter in the list
immediately follows it. In
Don’t Wrap mode, the module stops when the
last parameter in the list is displayed. To return to the first parameter,
you must scroll through the entire list in the opposite direction. The
Scroll Mode options globally affect all non-numeric parameters as they
appear on the control panel where you have made this setting. Numeric
values are not affected by Scroll Mode options.
Display Intensity
To accommodate different equipment room lighting conditions, you can
set the panel to five levels of display intensity: 100%, 75%, 50%, and
25%.
Screen Saver Timeout
To extend the life of the display device, the screen saver automatically
shuts off the display after a preset period of inactivity. Using the screen
saver timeout parameter, you can set the duration of inactivity after
which the control panel display turns off, or you can disable the screen
saver. The available time options are 5, 10, 20, and 30 minutes.
To exit the screen saver mode, press the control knob or any button. No
parameters will be changed when you exit the screen saver mode.
