5.11 Integrated Operation of the Bay Unit
5.11.1 Functional Description
This section summarizes those parameters by which you choose the UI language of
the bay unit and specify the measured values to be displayed in the “standby” display.
5.11.2 Setting Notes
LANGUAGE The parameter LANGUAGE (7101/BU) is used to set the UI language of the bay unit.
With the setting DEUTSCH the menus in the display of the bay unit appear in German.
With the setting ENGLISH, FRANCAIS, ESPANOL, ITALIANO, PYCCK. the
menus in the display of the bay unit appear in the respective target language.
OPER.1st L.
OPER.2nd L.
OPER.3rd L.
OPER.4th L.
The parameters OPER.1st L. (7120/BU), OPER.2nd L. (7122/BU),
OPER.3rd L. (7124/BU) and OPER.4th L. (7126/BU) are used to select the
measured value which will be displayed in the 1st, 2nd, 3rd and 4th line of the “stand-
by” display in 4-line mode.
You can choose from:
• The currents of the three phases IL1, IL2, IL3
• The earth fault current IE
• The differential currents of the three phases IdL1, IdL2, IdL3
• The stabilizing currents of the three phases IsL1, IsL2, IsL3
OPER.1st L.
OPER.2nd L.
OPER.3rd L.
OPER.4th L.
The parameters OPER. 1st L. (7121/BU), OPER.2nd L. (7123/BU),
OPER.3rd L. (7125/BU) and OPER.4th L. (7127/BU) are used to select the
mode of display for the measured value in the 1st, 2nd, 3rd and 4th line of the “stand-
by” display in 4-line mode.
With setting PRIMARY, the measured value will be displayed as primary value, i.e.
with the unit Ampere (A).
With setting SECONDARY, the measured value will be displayed as secondary value,
i.e. in percent of the rated current.
With the setting NORMALIZED, the measured value will be displayed as normalized
value, i.e. referring to the same reference current. The reference current is set in the
plant configuration.
Note
The parameter LANGUAGE (7101/BU) can only be set with the bay unit running in
stand-alone mode.
The value entered in the central unit for the parameter Language BU (5111A/CU)
is not affected by this.
With the bay unit linked to the cent
ral unit, the setting of this parameter is transmitted
from the central unit to the bay units. The local setting in the bay units is overwritten.
