Display
The programmable logic controller has a plain text display.
The display is automatically illuminated when entering or setting the controller.
After connecting the controller to the power supply, "System is being initialized..." appears
briefly on the display.
Should the display not be illuminated or the contrast is too strong/weak, you can adapt the dis-
play illumination. Refer to section 1.2.1.
