CHAPTER 5: SETTINGS
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 A protection summary is
displayed by navigating to a specific protection or control protection element and checking the desired bus box. Once the
desired 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.
The following settings are available.
— The trip bus output is blocked when the operand assigned to this setting is asserted.
TRIP BUS 1 BLOCK
— This setting specifies a time delay to produce an output depending on how output is used.
TRIP BUS 1 PICKUP DELAY
— This setting specifies a time delay to reset an output command. Set the time delay long enough
TRIP BUS 1 RESET DELAY
to allow the breaker or contactor to perform a required action.
