for operator.
In any case, the relay records any setting error between
I

and Neutral setting, and it signals this by means of a warning (see par. 3.5.2).
For
4-pole CBs only.

3.4.4.4 Modules
3.4.4.4.1 Communication module
Local or remote modes can be set after entering a password. The serial address can be displayed after entering a password. Baud Rate can be
set to 9600 and 19200 bit/s. The physical protocol provides for options: (8,E,1), (8,O,1), (8,N,2), (8,N,1). For further information on the communi-
cation module, see paragraph 4.2 in this manual.
3.4.5 Test Menu
Access to the Test menu is password-protected.
The menu shows the state of the CB; the dialog module (COM module), the state of the springs and the position of the CB; and in this submenu
you can have the CB opened or closed.
Using the “Trip Test” function, Trip disabling/enabling can be viewed. When enabled, the circuit breaker is opened. This function is only available
with a nil busbar current (use Vaux or battery unit).
On the page, only with Vaux, you can also see the state of “STATUS” circuit breaker, thus making sure that input is correctly wired.
