6.5.8 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. 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. The following example illustrates the password-protected output of
a manual trip command using the factory-set password. If the password has been
changed by the user (see the section entitled ‘Changing the Password’), the following
description will apply analogously.
