Eaton EDR 3000 - Programmable Logic; General Description

EDR-3000 IM02602003E
Programmable Logic
Available Elements (Equations):
Logic
General Description
The protective device includes programmable logic equations for programming inputs, outputs, blocking of protective
functions, and custom logic functions in the relay.
The logic provides control of the output relays based on the state of the inputs that can be chosen from the assignment
list (protective function pickups, protective function states, breaker states, system alarms, and module inputs). The
User can use the output signals of a logic equation as inputs in higher equations (e.g.: the output signal of logic
equation 10 might be used as an input of logic equation 11).
