GE Multilin L90 Line Current Differential System 5-2075 SETTINGS 5.7 CONTROL ELEMENTS55.7CONTROL ELEMENTS 5.7.1 OVERVIEWControl elements are generally used for control rather than protection. See the Introduction to Elements section at thebeginning of this chapter for further information.5.7.2 TRIP BUSPATH: SETTINGS ÖØ CONTROL ELEMENTS ÖØ TRIP BUS ÖØ TRIP BUS 1(6)The trip bus element allows aggregating outputs of protection and control elements without using FlexLogic™ and assign-ing them a simple and effective manner. Each trip bus can be assigned for either trip or alarm actions. Simple trip condition-ing such as latch, delay, and seal-in delay are available.The easiest way to assign element outputs to a trip bus is through the EnerVista UR Setup software A protection summaryis displayed by navigating to a specific protection or control protection element and checking the desired bus box. Once thedesired element is selected for a specific bus, a list of element operate-type operands are displayed and can be assignedto a trip bus. If more than one operate-type operand is required, it may be assigned directly from the trip bus menu.
