5.2 Overview
5.2.1 Introduction to elements
The main characteristics of an element are shown on a logic diagram. This includes the inputs, settings, fixed logic, and the
output operands generated. The previous chapter explains how to read a logic diagram, and the abbreviations used in a
diagram are defined in the Abbreviations chapter.
•
FUNCTION setting — This setting programs the element to operate when selected as “Enabled.” The factory default is
“Disabled.” Once “Enabled,” any element associated with the function becomes active and all options become
available.
• NAME setting — This setting is used to uniquely identify the element.
• PICKUP DELAY setting — This setting sets a time-delay-on-pickup, or on-delay, for the duration between the pickup
and operate output states.
• RESET DELAY setting — This setting is used to set a time-delay-on-dropout, or off-delay, for the duration between the
operate output state and the return to logic 0 after the input transits outside the defined pickup range.
• BLOCK setting — The default output operand state of all comparators is a logic 0 or “flag not set.” The comparator
remains in this default state until a logic 1 is asserted at the RUN input, allowing the test to be performed. If the RUN
input changes to logic 0 at any time, the comparator returns to the default state. The RUN input is used to supervise
the comparator. The BLOCK input is used as one of the inputs to RUN control.
• TARGET setting — This setting is used to define the operation of an element target message. When set to "Disabled,"
no target message or illumination of a faceplate LED indicator is issued upon operation of the element. When set to
“Self-Reset,” the target message and LED indication follow the operate state of the element and self-resets once the
operate element condition clears. When set to “Latched,” the target message and LED indication remains visible after
the element output returns to logic 0 until a RESET command is received by the relay.
• EVENTS setting — This setting is used to control whether the pickup, dropout, or operate states are recorded by the
event recorder. When set to “Disabled,” element pickup, dropout, or operate are not recorded as events. When set to
“Enabled,” events are created for
