6.2.2 Display Illumination
If none of the control keys are pressed, the display illumination will switch off
once the set “return time illumination” (setting in menu tree: “Par/Conf/LOC”)
has elapsed. Pressing any of the control keys will turn the display illumination on
again. In this case the control action that is normally triggered by that key will
not be executed. Reactivation of the display illumination is also possible by using
a binary input.
If continuous display illumination is required, the function “return time
illumination” (LOC: Return time illumin.) is set to
blocked .
6.2.3 Contrast of the Display
The contrast of the LC display can be adjusted by pressing 3 keys on the local
control panel at the same time, as follows:
