Multilin 469 Motor Management Relay ... - GE Digital Energy

5.5 S4 Output Relays
5.5.1 Description
5.5.2 Relay Reset Mode
CHAPTER 5: SETTINGS
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 nonoperated
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.
