5.2 A1 STATUS
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 Dig-
ital Input), phase and ground currents, RTD temperatures, voltages, frequency, power quantities, and analog
inputs. This information can be cleared using the S1 469 SETUP \ CLEAR DATA \ CLEAR TRIP COUNTERS setpoint.
5
Phase, differential, and ground currents are recorded 1 cycle prior to the trip. All other pre-trip data is
recorded 50 ms prior to the trip. Thus some values will not be recorded upon instantaneous trips dur-
ing a start if the trip is less than 50 ms.
