CHAPTER 6: ACTUAL VALUES
469 MOTOR MANAGEMENT RELAY – INSTRUCTION MANUAL
6–5
Immediately prior to issuing a trip, the 469 takes a snapshot of motor parameters and
stores them as pre-trip values that allow for troubleshooting after the trip occurs. The
CAUSE OF LAST TRIP
message is updated with the current trip and the screen defaults to
that message. All trip features are automatically logged as date and time stamped events
as they occur. This information may include motor speed (2-Speed feature or Assignable
Digital Input), phase and ground currents, RTD temperatures, voltages, frequency, power
quantities, and analog inputs. This information can be cleared using the
S1 469 SETUP
