振动、压力、流量等输入。图1–2：保护特征故障诊断通过预处理数据、事件记录、跟踪存储器和统计数据提供。在发出跳闸之前，469对测量参数进行快照，并将其与跳闸原因一起存储。在行程复位之前，可使用键查看行程前数据，或访问A1 STATUS？LAST trip data（A1状态）实际值。469事件记录器可存储多达40个时间和日期戳事件，包括行车前数据。每次发生跳闸时，469存储所有测量的交流电量的跳闸前8个周期和跳闸后8个周期的轨迹。跳闸计数器记录每种类型跳闸的发生次数。还记录RTD和模拟输入的最小值和最大值。这些功能使操作员能够快速确定问题。作为标准功能，469中包含功率计量。下表列出了通过前面板或通信端口可用的计量参数。51过载86过载锁定66启动/小时和启动间隔时间重启块（防反冲计时器）50短路和短路备用机械堵塞37 32欠电流/欠功率反向功率46电流不平衡50G/51G接地故障和接地故障备用87差动加速度49定子RTD 38轴承RTD其他RTD和环境RTD开路RTD报警短路/低RTD 27/59欠压/过压47相位反转81频率无功功率55/78功率因数模拟输入需求报警：A kW kvar kVA SR469自检，维修跳闸线圈监控焊接接触器断路器故障远程开关14速度开关和转速表跳闸减载开关压力开关振动开关19减压启动48过转矩远程启动/停止PROCTLA5.CDR不完整顺序（减压启动）强制继电器操作下一篇GE Multilin 469电机管理继电器1-3 1简介1.1概述1 469已配备具有3个功能齐全且独立的通信端口。前面板RS232端口可用于469设定点编程、本地询问或控制以及469固件的升级。计算机RS485端口可以连接到PLC、DCS或基于PC的用户界面程序。辅助RS485端口可用于第二PLC、DCS或PC软件的冗余或同时询问和/或控制。还有四个4至20 mA或0至1 mA（按订单规定）传感器输出，可分配给任何测量参数。这些输出的范围是可扩展的。下表列出了其他功能。1.1.2订单信息所有469项功能均为标准功能；没有选择。订购时必须指定相位CT次级、控制功率和模拟输出范围。469个差分CT输入可现场编程，用于1 A或5 A二次电流的CT。有两个接地CT输入，一个用于GE Power Management 50:0.025芯平衡CT，另一个用于具有1 a或5 a次级的接地CT，也可现场编程。VT输入将以三角形或Y形配置容纳VT。输出继电器始终是非故障安全的，服务继电器除外。469PC软件随每个单元提供。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 Õ× 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.

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.
