Outputs/LEDs can be configured to be activated by a single element or by a sum of several of them. These elements are
divided into eight groups, besides the
No definition element. Elements belonging to the same group can be assigned to
the same output/LED. Elements of different groups need to be assigned to different outputs/LEDs
i
.
In order to assign several elements to activate an output/LED, we first activate the OR button, next, click on the I/O
CONFIGURATION frame and select the desired element group, then choose the desired elements. In order to invert an
element, select the NOT button. Finally, click on the OK button.
The Output/LED logic can inverted selecting the general NOT button. Outputs can be latched, and LEDs can be set to be
fixed or blinking.
Example:If we want to assign a phase differential trip to an output or LED, the output or LED must be programmed with
32_1 trip, 32_2 trip and 32_3 trip elements . To do this, check the OR box in the corresponding Output or LED line (for this
case, Output1 and LED1). Then click on the OR button that appears in the I/O configuration column, select the desired
group (
ELEMENT TRIPS ) and click the I/O configuration box for every element that will be blocked by the input.
If an output or LED has to activate when the relay is not in local mode, select Local from the I/O configuration
dropdownlist. The OR button must not be checked.
Elements from different groups cannot be included in an OR type logic.
i. or select them in different logic diagrams (see logic configuration further on in this chapter and in Chapter 4. COMMUNICATIONS ) and
then choose the logic diagrams as the elements that will activate the output/LED
