Setting the screen saver
Introduction
You can set the following time intervals on the HMI device:
●
For the automatic activation of the screen saver
●
For automatically turning off the backlighting of the screen
When you do not undertake an operation within the configured interval, the configured
function will be activated automatically.
The screen saver will turn off with the following actions or backlighting will turn on once
again:
●
By pressing any key
●
By touching the touch screen
The function associated to the key or button will not be executed by this.
NOTICE
Turning off backlighting
The brightness of the backlighting decreases incrementally during its operational life.
You will increase the service life of the display considerably by turning off backlighting
rather than by reducing backlighting or using a screen saver.
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.
When the screen saver is active, the backlighting is reduced at the same time.
