5.6CONTROL ELEMENTS 5.6.1 OVERVIEW
Control elements are generally used for control rather than protection. See the Introduction to Elements section at the
beginning of this chapter for further information.
5.6.2 SETTING GROUPS
PATH: SETTINGS CONTROL ELEMENTS SETTINGS GROUPS
The Setting Groups menu controls the activation/deactivation of up to six possible groups of settings in the
GROUPED ELE-
MENTS
settings menu. The faceplate ‘Settings In Use’ LEDs indicate which active group (with a non-flashing energized
LED) is in service.
The
SETTING GROUPS BLK
setting prevents the active setting group from changing when the FlexLogic™ parameter is set to
"On". This can be useful in applications where it is undesirable to change the settings under certain conditions, such as the
breaker being open.
Each
GROUP n ACTIVATE ON
setting selects a FlexLogic™ operand which, when set, will make the particular setting group
active for use by any grouped element. A priority scheme ensures that only one group is active at a given time – the high-
est-numbered group which is activated by its
GROUP n ACTIVATE ON
parameter takes priority over the lower-numbered
groups. There is no “activate on” setting for Group 1 (the default active group), because Group 1 automatically becomes
active if no other group is active.
The
SETTING GROUP 1(6) NAME
settings allows to user to assign a name to each of the six settings groups. Once pro-
grammed, this name will appear on the second line of the
GROUPED ELEMENTS SETTING GROUP 1(6)
menu display.
The relay can be set up via a FlexLogic™ equation to receive requests to activate or de-activate a particular non-default
settings group. The following FlexLogic™ equation (see the figure below) illustrates requests via remote communications
(e.g.
VIRTUAL INPUT 1
) or from a local contact input (e.g. H7a) to initiate the use of a particular settings group, and requests
from several overcurrent pickup measuring elements to inhibit the use of the particular settings group. The assigned
VIR-
TUAL OUTPUT 1
operand is used to control the “On” state of a particular settings group.
