Operation
Structure of Parameters
Operation is hierarchically structured: The parameters are arranged in logical parameter
groups and assigned a numerical menu identification (see below).
Changing a Parameter Value
Entering Value from Selection List
In many cases, the device offers a number of entries in a selection list which you can
assign to a parameter. For these functions, you cannot enter anything other than a
selection from the displayed list.
You will see a single item of the selection list in the second line of the display.
• Change the display cyclically forwards or backwards with the control elements
or to select the desired entry from the list.
The control element operates like an “Enter” key: Use it to assign the displayed
list entry to the parameter. The device accepts the new setting, closes the input and
switches back to the next operating level up.
• The control element operates like a “Cancel” key: As soon as you press it, the
device closes the parameter input but retains the originally displayed value: It does
not save a changed setting!
For an example of assigning a value from a selection list, see “Operating examples” on
page 23.
