2.前端程序端口和運行繼電器附帶的469PC軟件的便攜式計算機。3.后端RS485端口和運行用戶編寫軟件的PLC/SCADA系統(tǒng)。這些方法中的任何一種都可以用于查看相同的信息。計算機使查看更加方便，因為可以同時查看許多變量。實際值消息被組織成邏輯組或頁面，以便于參考。在本章中，所有實際值消息均以方框形式進行說明和描述。這些消息圖示中顯示的所有值都假定469沒有連接任何輸入（除了控制電源）。除實際值消息外，當(dāng)出現(xiàn)某些情況時，還會出現(xiàn)診斷消息和閃爍消息。第5–27頁第5.8.1節(jié)：操作員診斷信息中描述了診斷信息。閃光信息為[ENTER]事件03↓ ?

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...
