6.11.8 Password-Protected Control Actions
Certain actions from the local control panel such as a manual trip command for
testing purposes can only be carried out by entering a password so as to prevent
unwanted output even though the global change-enabling function has been
activated (see section “Change-Enabling Function”).
This setup is designed to prevent accidental output and applies even when the
global change-enabling function has been activated. The password consists of a
pre-defined sequential key combination entered within a specific time interval. If
the password has been changed by the user (see section “Changing the
Password”), the following description will apply accordingly.
