Setting principle
Settings that cannot be made directly with the operating elements require programming.
For this purpose, the individual settings are structured in the form of operating pages
and operating lines, thus forming practical groups of settings.
The following example shows how to set the time of day and the date.
Example: “Setting the time of day“
• Press ESC to go one step back at a time, readjusted values are not be adopted
• If no setting is made for 8 minutes, the display returns automatically to the basic
display
• Operating lines may be hidden, depending on the type of controller, the configuration
made and the user level
