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 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.
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

to allow the breaker or contactor to perform a required action.

bus.
— This setting enables or disables latching of the trip bus output. This is typically used when lockout is

required or user acknowledgement of the relay response is required.
— The trip bus output is reset when the operand assigned to this setting is asserted. Note that the
TRIP BUS 1 RESET
operand is pre-wired to the reset gate of the latch, As such, a reset command from the front panel interface or via
communications resets the trip bus output.
