5.7 Control elements
5.7.1 Overview
Control elements are used for control rather than protection. See the Introduction to Elements section at the beginning of
this chapter for information.
5.7.2 Trip bus
SETTINGS  CONTROL ELEMENTS  TRIP BUS  TRIP BUS 1(6)
The trip bus element allows aggregating outputs of protection and control elements without using FlexLogic and assigning
them a simple and effective manner. Each trip bus can be assigned for either trip or alarm actions. Simple trip conditioning
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 software under Settings > Protection
Summary. Navigate to a specific protection or control protection element and check the bus box by hovering over the
blank check box and selecting an option that displays. Once the required element is selected for a specific bus, a list of
element operate-type operands are displayed and can be assigned to a trip bus. If more than one operate-type operand is
required, it can be assigned directly from the trip bus menu.
