7.2.3.  Entries and changes using the operation panel  
Changes on the device are always made in the following steps: 
•  Log into the device  
•  Complete and confirm the changes on the device 
•  Log out of the device 
 
Use the Users main display to log in, confirm and log out  see section 7.3.11 System display Users 
(Login/Logout / Password). The procedure for changing parameters is also described there. 
Values which can be changed are displayed in white boxes. These are editable boxes. These editable 
boxes appear depending on the login status and user rights. Changes are not finally entered and 
saved  to  the  device  until  the  user  has  explicitly  confirmed  them.  If  the  user  has  logged  out 
beforehand or is logged out due to another event without confirming the changes, any changes that 
have been made will be discarded. 
Entries and changes can be made either using a drop-down list or the displayed keypad. 
 
Changes using a drop-down list 
are shown in the following example.  
A  drop-down  list  can  be  identified  by  the 
small  gray  box  with  a  triangle  next  to  the 
value  to  be  changed,  in  this  example  after 
month and day.  
The view will change when you click on it, in 
the example the year. 
Figure 7.11: Drop-down list open 
The drop-down list is opened and displays the available values. The superimposition keys enable 
you to select a value from the drop-down box. Your selection then has a blue background (in the 
example 2020). After this user action, a confirmation of the selection is requested, which is why the 
buttons at the bottom of the display area are marked with a check or an X symbol. See figure.
