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
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

SETUP CLEAR DATA
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 during a start if the trip is

less than 50 ms.
