Display and Push-Buttons
The pressure-sensitive membrane of the front panel consists of a plastic coating. All keys have been designed as
touch-sensitive membrane switch elements. The display is an LC display, comprised of 2 lines with 16 characters
each, which are indirectly illuminated in red. The contrast of the display can be infinitely adjusted via a rotary
potentiometer positioned on the left side. The configuration plug is located on the left side of the unit. The direct
configuration cable (DPC) connects there.
