Setting the screen saver
You can set the following time intervals in the Control Panel:
●
Automatic activation of the screen saver
●
Automatic reduction in the display backlighting
The HMI device exhibits the following behavior based on the settings:
●
The screen saver is automatically activated if the HMI device is not operated within the
specified period of time.
●
Touching the touch screen switches off the screen saver.
The reduction of the backlighting is also canceled. The function assigned to the button is
not triggered in this case.
NOTICE
Reducing backlighting
The brightness of the backlighting decreases with increasing time in service.
To avoid shortening the service life of the backlighting unnecessarily, you can activate
reduction of the backlighting.
Activating the screen saver
Display content that is not changed for a long period can remain dimly visible in the
background for a long time. This effect is reversible.
Therefore, activate the screen saver. When the screen saver is active, the backlighting is
also reduced.
Note
The screen saver has operation protection. Do not use this as a substitute for the security
mode as described in "Changing password protection (Page 64)".
