The virtual inputs can be reprogrammed as described later in this document.
In the factory default programming, most of the inputs provide just a “straight” connection between a
physical input and a logic input (Inputs 7 to 72). However, note that any physical input can be mapped
to any number of logic inputs on the GARD mapping page.
In the default programming, Inputs 1 to 4 are also programmed to the optional front Push Button
Interface (PBI). This means that the logic input has a parallel path and can be asserted via a front push
button, if so configured on the GARD PBI setting page.
The default programming assigns logic Input 5 for a 52B function. The physical input can be a 52a or a
52b. In addition, the logic accommodates dual breaker inputs. The System logic provides the necessary
logic for achieving this function, and appropriate settings need to be made on the GARD Option
settings page.
11.4 OUTPUTS
The factory default logic for the distance relay provides 64 virtual outputs. The system logic multiplies
some of these, assigns triggers and latches them for use by LED indicators as shown in the following
table.
