5-218 C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUALCONTROL ELEMENTS CHAPTER 5: SETTINGS5The trip bus element allows aggregating outputs of protection and control elements without using FlexLogic and assigningthem a simple and effective manner. Each trip bus can be assigned for either trip or alarm actions. Simple trip conditioningsuch 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 A protection summary isdisplayed 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 can be assigned directly from the trip bus menu.Figure 5-112: Trip bus fields in the protection summaryThe following settings are available.TRIP BUS 1 BLOCK — The trip bus output is blocked when the operand assigned to this setting is asserted.TRIP BUS 1 PICKUP DELAY — This setting specifies a time delay to produce an output depending on how output is used.TRIP BUS 1 RESET DELAY — This setting specifies a time delay to reset an output command. Set the time delay long enoughto allow the breaker or contactor to perform a required action.TRIP BUS 1 INPUT 1 to TRIP BUS 1 INPUT 16 — These settings select a FlexLogic operand to be assigned as an input to the tripbus.
