4.5 S4 OUTPUT RELAYS

4.5S4 OUTPUT RELAYS
Five of the six output relays are always non-failsafe, R6 Service is always failsafe. As failsafe, R6 relay will be energized
normally and de-energize when called upon to operate. It will also de-energize when control power to the 469 is lost and
therefore, be in its operated state. All other relays, being non-failsafe, will be de-energized normally and energize when
called upon to operate. Obviously, when control power is lost to the 469, the output relays must be de-energized and there-
fore, they will be in their non-operated state. Shorting bars in the drawout case ensure that when the 469 is drawn out, no
trip or alarm occurs. The R6 Service output will however indicate that the 469 has been drawn out.

A latched trip or alarm may be reset at any time, providing that the condition that caused the trip or alarm is no longer
present. Unlatched trips and alarms will reset automatically once the condition is no longer present. If any condition may be
reset, the Reset Possible LED will be lit. All Block Start features reset automatically when the lockout time has expired and
the trip has been reset.
The other relays may be programmed to All Resets which allows reset from the front keypad or the remote reset switch
input or the communications port. Optionally, relays 1 through 6 may be programmed to reset by the "Remote Reset Only"
(by the remote reset switch input or the communications port) or "Keypad Reset Only" (reset only by relay keypad).
NO trip or alarm element must EVER be assigned to two output relays where one is Remote Reset Only and
the other is Keypad Reset Only. The trip or alarm will be unresettable if this occurs.
WARNING
For example, serious trips such as Short Circuit and Ground Fault may be assigned to the R2 Auxiliary relay so that they
can only be reset via the remote reset terminals (D18 and D23) or the communication port. The remote reset terminals
should be connected to a keyswitch so that only authorized personnel could reset such a critical trip.
• Assign only Short Circuit and Ground Fault to the R2 Auxiliary relay
