CHAPTER 4: SETPOINTS OUTPUTS
869 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 4–97
Output Relay 2 (F4)
programmed as Close
Output Relay 2 (F4) is labeled CLOSE/AUX on the wiring diagram. As suggested by that
name, it can be used as a Close relay or an Auxiliary relay. The selection can be made in
Setpoints > System > Breakers (Contactor) > Breakers 1 (Contactor 1) > Close Relay Select. If
the selected value of Close Relay Select setting is Off, the Output Relay 2 functions as an
Auxiliary relay. If the selected value is Relay 2, the Output Relay 2 functions as a Close relay.
The default value is Off. The description below applies to both Relay 2 “Close” functionality.
For the Relay 2 “auxiliary” functionality, see the figure: Auxiliary Relays generic logic at the
end of this section.
Path:
Setpoints > Outputs > Output Relays > Aux Relay 2 (Close)
NOTE:
The output relays selected under the Breaker menu for breaker closing are excluded from
the list of outputs for selection under the menus of all elements providing such output relay
selection.
NOTE:
If Aux Relay 2 is selected for Breaker Close or Contactor Close, the relay name from the
Output Relays menu changes to “Close”. If Aux Relay 2 is not selected, the name reverts to
“Aux Relay 2”.
