振動、壓力、流量等輸入。圖1–2：保護特征故障診斷通過預處理數據、事件記錄、跟蹤存儲器和統計數據提供。在發出跳閘之前，469對測量參數進行快照，并將其與跳閘原因一起存儲。在行程復位之前，可使用鍵查看行程前數據，或訪問A1 STATUS？LAST trip data（A1狀態）實際值。469事件記錄器可存儲多達40個時間和日期戳事件，包括行車前數據。每次發生跳閘時，469存儲所有測量的交流電量的跳閘前8個周期和跳閘后8個周期的軌跡。跳閘計數器記錄每種類型跳閘的發生次數。還記錄RTD和模擬輸入的最小值和最大值。這些功能使操作員能夠快速確定問題。作為標準功能，469中包含功率計量。下表列出了通過前面板或通信端口可用的計量參數。51過載86過載鎖定66啟動/小時和啟動間隔時間重啟塊（防反沖計時器）50短路和短路備用機械堵塞37 32欠電流/欠功率反向功率46電流不平衡50G/51G接地故障和接地故障備用87差動加速度49定子RTD 38軸承RTD其他RTD和環境RTD開路RTD報警短路/低RTD 27/59欠壓/過壓47相位反轉81頻率無功功率55/78功率因數模擬輸入需求報警：A kW kvar kVA SR469自檢，維修跳閘線圈監控焊接接觸器斷路器故障遠程開關14速度開關和轉速表跳閘減載開關壓力開關振動開關19減壓啟動48過轉矩遠程啟動/停止PROCTLA5.CDR不完整順序（減壓啟動）強制繼電器操作下一篇GE Multilin 469電機管理繼電器1-3 1簡介1.1概述1 469已配備具有3個功能齊全且獨立的通信端口。前面板RS232端口可用于469設定點編程、本地詢問或控制以及469固件的升級。計算機RS485端口可以連接到PLC、DCS或基于PC的用戶界面程序。輔助RS485端口可用于第二PLC、DCS或PC軟件的冗余或同時詢問和/或控制。還有四個4至20 mA或0至1 mA（按訂單規定）傳感器輸出，可分配給任何測量參數。這些輸出的范圍是可擴展的。下表列出了其他功能。1.1.2訂單信息所有469項功能均為標準功能；沒有選擇。訂購時必須指定相位CT次級、控制功率和模擬輸出范圍。469個差分CT輸入可現場編程，用于1 A或5 A二次電流的CT。有兩個接地CT輸入，一個用于GE Power Management 50:0.025芯平衡CT，另一個用于具有1 a或5 a次級的接地CT，也可現場編程。VT輸入將以三角形或Y形配置容納VT。輸出繼電器始終是非故障安全的，服務繼電器除外。469PC軟件隨每個單元提供。input such as vibration, pressure, flow, etc. Figure 1–2: PROTECTION FEATURES Fault diagnostics are provided through pretrip data, event record, trace memory, and statistics. Prior to issuing a trip, the 469 takes a snapshot of the measured parameters and stores them with the cause of the trip. This pre-trip data may be viewed using the key before the trip is reset, or by accessing the A1 STATUS ?× LAST TRIP DATA actual values. The 469 event recorder stores up to 40 time and date stamped events including the pre-trip data. Each time a trip occurs, the 469 stores a trace of 8 cycles pre-trip and 8 cycles post-trip for all measured AC quantities. Trip counters record the number of occurrences of each type of trip. Minimum and maximum values for RTDs and analog inputs are also recorded. These features enable the operator to pinpoint a problem quickly and with certainty. Power metering included with the 469 as a standard feature.

The front panel RS232 port may be used for 469 setpoint programming, local interrogation or control, and upgrading of 469 firmware. The Computer RS485 port may be connected to a PLC, DCS, or PC based user interface program. The Auxiliary RS485 port may be used for redundancy or simultaneous interrogation and/or control from a second PLC, DCS, or PC software. There are also four 4 to 20 mA or 0 to 1 mA (as specified with order) transducer outputs that may be assigned to any measured parameter. The range of these outputs is scalable. Additional features are outlined in the table below. 1.1.2 ORDER INFORMATION All 469 features are standard; there are no options. The phase CT secondaries, control power, and analog output range must be specified at the time of order. The 469 differential CT inputs are field programmable for CTs with 1 A or 5 A secondaries. There are two ground CT inputs, one for the GE Power Management 50:0.025 core balance CT and one for a ground CT with a 1 A or 5 A secondary, also field programmable. The VT inputs will accommodate VTs in either a delta or wye configuration. The output relays are always non-failsafe with the exception of the service relay. The 469PC software is provided with each unit.
