Operating temperature for the display
To increase the service life of the display, the display switches off when the permitted
operating temperature is exceeded. When the display has cooled down again, it switches
back on automatically. When the display is switched off, the LEDs continue to show the status
of the CPUs.
You can find more information on display temperatures in the technical specifications in the
CPU manuals.
-CPUs have no internal temperature measurement. Reading out the internal
temperature of the R/H-CPUs is not supported.
