2. The front program port and a portable computer running the 469PC software supplied with the relay. 3. The rear terminal RS485 port and a PLC/SCADA system running user-written software. Any of these methods can be used to view the same information. A computer makes viewing much more convenient, since many variables may be viewed at the same time. Actual value messages are organized into logical groups, or pages, for easy reference. All actual value messages are illustrated and described in blocks throughout this chapter. All values shown in these message illustrations assume that no inputs (besides control power) are connected to the 469. In addition to the actual value messages, there are also diagnostic messages and flash messages that appear when certain conditions occur. Diagnostic messages are described in Section 5.8.1: DIAGNOSTIC MESSAGES FOR OPERATORS on page 5–27. Flash messages are [ENTER] EVENT 03 ↓ ?

If the motor has been tripped and the 469 has not yet been reset, the MOTOR STATUS value will be "Tripped". The MOTOR THERMAL CAPACITY USED reflects an integrated value of both the Stator and Rotor Thermal Capacity Used. The values for ESTIMATED TRIP TIME ON OVERLOAD appear whenever the 469 picks up on the overload curve. ? MOTOR STATUS ?

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 \ CLEAR DATA \ CLEAR TRIP COUNTERS setpoint. 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. 0 kW 0 kVA 0 kvar PreTrip Range: –50000 to 50000 kVA Not seen if VT Connection is programmed as None POWER FACTOR PreTrip: 0.00 Range: 0.01 to 0.99 Lead or Lag, 0.00, 1.00 Not seen if VT Connection is programmed RTD # 7 8 9 10 11...
