The 469 has three basic categories of protection elements. They are trips, alarms, and
blocks.
• TRIPS: A 469 trip feature may be assigned to any combination of the two Auxiliary
relays, 2 AUXILIARY and 3 AUXILIARY, in addition to the 1 TRIP Relay. If a Trip becomes
active, the appropriate LED (indicator) on the 469 faceplate will illuminate to show
which of the output relays has operated. In addition to the Trip relay(s), a trip will
always operate the Block Start relay. Trip features are may be programmed as latched
or unlatched. Once a relay has been operated by a latched trip, a reset must be
performed to clear the trip when the condition is no longer present. If there is a
lockout time, the Block Start relay will not reset until the lockout time has expired. If an
unlatched trip feature becomes active, that trip will reset itself (and associated output
relays) as soon as the condition that caused the trip ceases. Immediately prior to
issuing a trip, the 469 takes a snapshot of motor parameters and stores them as pre-
trip values which will allow for troubleshooting after the trip occurs. The cause of last
trip message is updated with the current trip and the 469 display defaults to that
message. All trip features are automatically logged and date and time stamped as
they occur. In addition, all trips are counted and logged as statistics such that any long
term trends may be identified.
• ALARMS: A 469 alarm feature may be assigned to operate any combination of three
output relays, 4 ALARM, 3 AUXILIARY, and 2 AUXILIARY. Also an alarm may be assigned
to NONE. When set to 'NONE', an alarm may record an event without operating one of
the alarm or auxiliary relays. When an Alarm becomes active, the appropriate LED
(indicator) on the 469 faceplate will illuminate when an output relay(s) has operated.
Each alarm feature may be programmed as latched or unlatched. Once a latched
alarm feature becomes active, the reset key must be pressed to reset that alarm. If the
