S4 Output Relays

Five of the six output relays are always non-failsafe; the 6 SERVICE relay is always
failsafe. As failsafe, the 6 SERVICE 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
therefore, 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 the
6 SERVICE relay 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 not be resettable if this occurs.
For example, serious trips such as Short Circuit and Ground Fault may be assigned
to the 2 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 2 AUXILIARY relay
• Program to "Remote Reset Only"
