2.前端程序端口和运行继电器附带的469PC软件的便携式计算机。3.后端RS485端口和运行用户编写软件的PLC/SCADA系统。这些方法中的任何一种都可以用于查看相同的信息。计算机使查看更加方便，因为可以同时查看许多变量。实际值消息被组织成逻辑组或页面，以便于参考。在本章中，所有实际值消息均以方框形式进行说明和描述。这些消息图示中显示的所有值都假定469没有连接任何输入（除了控制电源）。除实际值消息外，当出现某些情况时，还会出现诊断消息和闪烁消息。第5–27页第5.8.1节：操作员诊断信息中描述了诊断信息。闪光信息为[ENTER]事件03↓ ❙ [ENTER]事件40 5-2 469电机管理继电器GE Power Management 5.2 A1状态5实际值5 5.2 A1状态5.2.1电机状态这些消息描述了任何给定时间点的电机状态。如果电机已跳闸且469尚未复位，则电机状态值将为“跳闸”。所用电机热容量反映了所用定子和转子热容量的综合值。每当469在过载曲线上出现时，估计过载跳闸时间的值就会出现。❙ 电动机状态❙ [输入]了解更多电机状态：停止范围：跳闸、停止、启动、运行、过载电机热容量使用：0%范围：0%至100%过载估计跳闸时间：从不范围：0至10000秒，从不电机速度：低速范围：高速，只有在启用双速电机功能时才会看到低速信息ENTER ESCAPE♥Message ESCAPE Message ESCAPE MESAGE ESCAPE GE Power Management 469 Motor Management Relay 5-3 5 ACTUAL VALUES 469获取电机参数的快照，并将其存储为跳闸前值，以便在跳闸发生后进行故障排除。最后一次跳闸的原因信息将更新为当前跳闸，屏幕默认为该信息。所有行程特性在发生时自动记录为日期和时间戳事件。该信息可能包括电机速度（2速功能或可分配数字输入）、相位和接地电流、RTD温度、电压、频率、功率量和模拟输入。可使用S1 469 SETUP\CLEAR DATA\CLEAR TRIP COUNTERS（S1 469设置\清除数据\清除跳闸计数器）设置点清除此信息。跳闸前1个周期记录相位、差分和接地电流。在跳闸前50 ms记录所有其他跳闸前数据。因此，如果跳闸小于50 ms，则在启动期间的瞬时跳闸时不会记录一些值。0 kW 0 kVA 0 kvar预跳闸范围：–50000至50000 kVA如果VT连接编程为无功率因数预跳闸：0.00范围：0.01至0.99超前或滞后，0.00，1.00如果VT连接编程为RTD#7 8 9 10 11，则不可见…范围：1至12反映RTD具有短路/低温报警欠压报警Vab=3245 V 78%额定范围：0至20000 V；此处显示最低线间电压额定值的50至99%，过压报警Vab=4992 V 120%范围：0至20000 V；
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 ↓ ❙ [ENTER] EVENT 40 5-2 469 Motor Management Relay GE Power Management 5.2 A1 STATUS 5 ACTUAL VALUES 5 5.2 A1 STATUS 5.2.1 MOTOR STATUS These messages describe the motor status at any given point in time. 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 ❙ [ENTER] for more MOTOR STATUS: Stopped Range: Tripped, Stopped, Starting, Running, Overload MOTOR THERMAL CAPACITY USED: 0% Range: 0 to 100% ESTIMATED TRIP TIME ON OVERLOAD: Never Range: 0 to 10000 sec., Never MOTOR SPEED: Low Speed Range: HIgh Speed, Low Speed Message seen only if Two Speed Motor feature is enabled ENTER ESCAPE ð ð MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE GE Power Management 469 Motor Management Relay 5-3 5 ACTUAL VALUES 469 takes a snapshot of motor parameters and stores them as pre-trip values that allow for troubleshooting after the trip occurs. 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...
