Setting the screen saver

You can set the following time intervals on the HMI device:
● Automatic reduction of the screen backlighting
● Automatic activation of the screensaver
The configured function is automatically activated if the HMI device is not operated within the
specified period of time.
NOTICE
Reduce backlighting
The brightness of the backlighting decreases incrementally during its operational life.
In order to not shorten the operational lifetime of the backlighting unnecessarily, activate
the backlighting reduction.
Activating the screen saver
Screen contents may occasionally leave a burn-in effect in the background if they appear
too long.
This burn-in effect will automatically disappear after a certain amount of time if the
screensaver is activated, for example. The longer the same content is displayed on the
screen, the longer it will take for the burn-in effect to disappear.
Generally, you should always activate the screen saver.
The "Blank Screen" setting is used to switch off backlighting.
Requirement
The Control Panel is open.
Procedure

1. Open the "Screensaver" dialog with the ScreenSaver icon.
2. Enter the number of minutes before backlighting is to be reduced and the screen saver is
94
to be activated.
Value range in minutes: 5 to 71582. "0" disables the feature.
