If you want to lock buttons and to authorize only certain users to use these pushbuttons, follow these steps:
Global Control/Administration. On the Authorisation tab you need to create at least one authorisation group (see Authorisation - Authorisation Groups).User Accounts tab and create at least one user. In the Member of Groups area, assign the users to the desired user groups and define a personal PIN for each user (see User Accounts).Authorisation tab, select the respective buttons one after the other and define which authorisation groups are allowed to use these buttons (see Authorisation - Limiting Access to Keys).Authorisation tab (see Authorisation - PIN Input Conditions) select two logic sources. To login at the console, these two logic conditions need to be true at the same time for approximately 3 seconds (e.g., pressing two buttons). Every digit of the PIN needs to be chosen with the main encoder and must be confirmed with the OK key.
