CHAPTER 5: SETTINGS CONTROL ELEMENTSN60 NETWORK STABILITY AND SYNCHROPHASOR MEASUREMENT SYSTEM – INSTRUCTION MANUAL 5-1915SETTING GROUPS FUNCTION — When Enabled, allows setting groups other than group 1 (the default active group) to beactivated. The default setting group is forced active while the SETTING GROUPS FUNCTION setting is Disabled.SETTING GROUPS BLK — Prevents the active setting group from changing when the selected FlexLogic operand is "On." Thiscan be useful in applications where it is undesirable to change the settings under certain conditions, such as during acontrol sequence.GROUP 2 ACTIVATE ON to GROUP 6 ACTIVATE ON — Selects a FlexLogic operand which, when set, makes the particular settinggroup active for use by any grouped element. A priority scheme ensures that only one group is active at a given time — thehighest-numbered group that is activated by its 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 noother group is active.SETTING GROUP 1 NAME to SETTING GROUP 6 NAME — Allows the user to assign a name to each of the six settings groups.Once programmed, this name appears 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-defaultsettings group. The following FlexLogic equation (see the following figure) illustrates requests via remote communications(for example, VIRTUAL INPUT 1 ON) or from a local contact input (for example, CONTACT IP 1 ON) to initiate the use of a particularsettings group, and requests from several overcurrent pickup measuring elements to inhibit the use of the particularsettings group. The assigned VIRTUAL OUTPUT 1 operand is used to control the “On” state of a particular settings group.Figure 5-94: Example of FlexLogic control of a setting groupA setting group selection can also be made by the IEC 61850 MMS service SelectActiveSG to the control block @Master/LLN0.SGCB. The priority scheme mentioned makes active the highest numbered group selected by SelectActiveSG or theGROUP ACTIVATE ON settings. The SelectActiveSG selection has a default value of 1, so until a higher SelectActiveSGselection is received, the GROUP ACTIVATE ON settings control the active group.The most recent SelectActiveSG selection is preserved while the UR is powered down or reset.If it becomes necessary to cancel the SelectActiveSG selection without using a SelectActiveSG service request, change theSETTING GROUPS FUNCTION setting to Disabled. This resets the SelectActiveSG selection to 1.5.8.4 Selector switchSETTINGS  CONTROL ELEMENTS  SELECTOR SWITCH  SELECTOR SWITCH 1(2) SELECTOR SWITCH 1  SELECTOR 1 FUNCTION:DisabledRange: Disabled, Enabled SELECTOR 1 FULLRANGE: 7Range: 1 to 7 in steps of 1101 VIRT IP 1 ON (VI1)2 CONT IP 1 ON (H5A)3OR (2)OR (2)4 PHASE TOC1 PKP5 NOT6 PHASE TOC2 PKP7 NOT8AND (3)AND (3)9= VIRT OP 1 (VO1)= VIRT OP 1 (VO1)END 842789A1.CDR
