Use the protection summary window for programming all of the elements and output
relays needed for the application. Please note, that the output relays selected for breaker
closing are excluded from the menus of all elements, and they are made inactive (cannot
be selected) in the Protection Summary menu. The check boxes related to these outputs
automatically become inactive, and they cannot be checked/unchecked by the user.
The check boxes for the relay outputs assigned for breaker tripping will automatically
become inactive (non-selectable), if the function of an element is set to Alarm, Latched
Alarm, or Configurable. In all other cases, the check boxes corresponding to those output
relays will be active, and available for selection.
Before placing the relay in operation, setpoints defining system characteristics, inputs,
relay outputs, and protection settings must be entered, using one of the following
methods:
• Front panel, using the keypad and the display.
• Front USB port, connected to a portable computer running the EnerVista 8 Series
Setup software.
