4.1.3
Blockings
The device provides a function for blocking of the trip command. In addition, most of the
protection stages can be blocked individually.
WARNING!
Make absolutely sure that no illogical or even life-threatening blockings are allocated.
Make sure that you do not carelessly deactivate protection functions which have to be
available according to the protection concept.
4.1.3.1 Switching Protection Functions On or O
Each of the modules can be switched on or o (permanently). This is achieved when the
parameter »Function« is set to “Active” or “Inactive” in the respective module.
• First, in the menu [Device planning] there is for each protection stage a•
parameter »Mode«. It takes the protection stage completely out of operation (or sets
it into operation).
Every protection stage that it not required by the protection concept should
indeed be deactivated this way, because it then no longer uses any device-internal
resources (CPU time, memory).
Furthermore, activating and deactivating of protection stages automatically takes
into account all dependencies that might exist between dierent protection stages.
And a deactivated protection stage disappears completely from all menu branches
(with the sole exception of the setting »Mode«, that allows for (re-)activating the
protection stage.
• In addition to this kind of de-/activation, there is for each protection stage a•
setting »Function«, that can be “Active” or “Inactive”. The protection stage is kept
operating also for »Function« = “Inactive”, but it is not protecting, i. e. it is “switched
o”.
