Language BU The parameter Language BU (5111A/CU) is used to select the UI language of the
bay units. The language of the annunciations displayed in the central unit is set via the
configuration of the central unit. If the bay unit is operated without a central unit, the
language is set locally via a parameter (7101/BU).
With the setting Deutsch, the menus in the bay unit display and the parameters and
annunciations in DIGSI are displayed in German.
With the setting English, French, Italian, Russian or Spanish the menus
in the bay unit display and the parameters and annunciations in DIGSI are displayed
in the selected language.
Independent of the above mentioned remarks on the device operation, for DIGSI, the
language settings of the DIGSI Device Manager apply.
I> MAN TRIP The parameter I> MAN TRIP (6316/CU) is used to set the threshold of the feeder
current for the circuit breaker test. The feeder current that is allowed to flow during the
test must be less than this threshold. Thus, an unintentional tripping of a feeder in op-
eration can be prevented.
I>TRIP The parameter I>TRIP (XX13/CU) is used to set the threshold of the feeder current
for the trip release.
The setting of the parameter depends on the lowest short-circuit current to be expect-
ed.
A TRIP command will be performed selectively for each feeder as soon as the feeder
current exceeds this threshold. The set value refers to the rated CT current. If you set
a feeder to 0, this feeder will be tripped without an I>query.
Bay status The parameter Bay status (XX12/CU) is used to select the operating status of the
bay unit.
With setting in service the bay unit will be in service.
With setting out of service the bay unit will be out of service.
With setting maintenance the bay unit will be in maintenance mode. In that, the iso-
lator replica is frozen in this operating state.
Note
The setting of the bay status can only be changed back at the unit where it was first
set. Possible are, for example, binary inputs, control panel or settings via DIGSI.
