3.6 Using energy-saving functions
3.6.1 Application
The energy required for display backlighting, up to 40%, makes up a large part of the total
power consumption of an HMI device. To reduce energy consumption, the Comfort HMI
devices come equipped with LED backlighting. You can infinitely dim the display or turn it off
completely. You will see energy savings of up to 40% this way.
You can set the display brightness as soon as you configure the HMI device in the Control
Panel.
The energy-saving functions of the Comfort HMI device lower the operating costs during
operation while increasing the display service life.
3.6.2 Configuring the energy-saving function
Introduction
You have the following options to use the energy-saving functions of the HMI device:
● Activate the "Blank Screen" screen saver.
● Control the display brightness using the system function.
The listed options do not preclude each other. This way you can develop an intelligent
energy-saving concept in which the operator reduces the brightness as required, for
example. In case of long periods of inactivity, the display can be switched off automatically
after a certain period of time.
