GE Multilin L60 Line Phase Comparison Relay 5-1575 SETTINGS 5.6 CONTROL ELEMENTS55.6CONTROL ELEMENTS 5.6.1 OVERVIEWControl elements are generally used for control rather than protection. See the Introduction to Elements section at thebeginning of this chapter for further information.5.6.2 SETTING GROUPSPATH: SETTINGS ÖØ CONTROL ELEMENTS Ö SETTINGS GROUPSThe 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 energizedLED) 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 thebreaker being open.Each GROUP n ACTIVATE ON setting selects a FlexLogic™ operand which, when set, will make the particular setting groupactive 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-numberedgroups. There is no “activate on” setting for Group 1 (the default active group), because Group 1 automatically becomesactive 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 Ö 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 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 requestsfrom 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.
