•跟踪存储器缓冲区：设置要捕获的跟踪数和捕获的10个波形中每个波形的周期数。注：每条记录道采集10个波形，显示所有电流和电压。•DISPLAY UPDATE INTERVAL（显示更新间隔）：设置在显示计量电流和电压读数之前对其进行平均的持续时间。它不会以任何方式影响继电器保护或功能计时。当读数跳动时，它可用于稳定显示。•电机负载过滤器间隔：该值（非零时）使用运行平均技术对编程循环数的电流和PF进行平均。该设定值适用于以低转速运行并驱动往复负载的同步电机。可以通过使用电流波形捕获来确定要平均的周期数。从该波形可以确定完成一个冲程的循环数。该值可用作电机负载过滤间隔的起点。可能需要额外的微调。警告：此平均值可能会使每个平均周期的跳闸/报警时间增加16.7 ms。❙ 偏好❙ [输入]获取更多默认消息周期时间：2.0秒范围：0.5到10.0秒，步骤：1默认消息超时：300秒范围：10到900秒，步骤1平均电机负载计算周期：15分钟范围：1到90分钟，步骤1温度显示：摄氏度范围：摄氏度，Farenheit跟踪内存触发器位置：25%范围：1至100%，步骤：跟踪内存缓冲器8x14周期范围：1x64、2x42、3x32、4x35，5x21、6x18、7x16、8x14、9x12、10x11、11x10、12x9、13x9、14x8、15x8、16x7设置波形捕获缓冲区的分区。显示更新间隔：0.4秒范围：0.1至60秒，步长：0.1电机负载过滤器间隔：0周期范围：0至32周期（0=关闭）；步骤：1注意：如果频率设置为变量ENTER ESCAPE♥♥MESSAGE ESCAPE MESSAGE ESCAPE MESAGE ESCAPE MISSAGE ESCAP MESSAGE ESCAPE MESSION ESCAPE MESSAGE 4-6 469电机管理继电器GE Power Management 4.2 S1 469 SETUP 4 Setpoint PROGRAMMING 4 4.2.3串行端口469具有3个串行通信端口，支持Modbus协议的子集。前面板RS232具有9600的固定波特率，1个起始、8个数据和1个停止位的固定数据帧，无奇偶校验。前端端口仅用于本地使用，无论编程的从属地址如何，都会做出响应。此端口可以连接到运行469PC的个人计算机。该软件可以下载和上传设定点文件以及升级469固件。对于RS485通信，每个469必须具有从1到254的唯一地址。地址0是所有中继检测到的广播地址。地址不必是连续的，但没有两个单元可以具有相同的地址，否则将发生错误。通常，添加到链路的每个单元使用从1开始的下一个更高的地址。波特率可以选择为300、1200、2400、4800、9600或19200。数据帧固定在1个起始位、8个数据位和1个停止位，而奇偶校验是可选的。计算机RS485端口是用于连接DCS、PLC或PC的通用端口。辅助RS485端口可用于冗余，也可用于与辅助GE电源管理设备通信。
• TRACE MEMORY BUFFERS: Sets the number of traces to capture and the number of cycles for each of the 10 waveforms captured. Note: 10 waveforms are captured for each trace, showing all currents and voltages. • DISPLAY UPDATE INTERVAL: Sets the duration for which the metered current and voltage readings are averaged before being displayed. It does not affect relay protection or function timing in any way. It can be used to steady the display when readings are bouncing. • MOTOR LOAD FILTER INTERVAL: This value (when non-zero) averages current and PF for the programmed number of cycles using a running average technique. This setpoint is intended for use on synchronous motors running at low RPM and driving reciprocating loads. The number of cycles to average can be determined by using current waveform capture. The number of cycles to complete one stroke can be determined from this waveform. This value can be used as the starting point for the motor load filter interval. Additional fine tuning may be required. WARNING: This averaging may increase trip/alarm times by 16.7 ms for every cycle averaged. ❙ PREFERENCES ❙ [ENTER] for more DEFAULT MESSAGE CYCLE TIME: 2.0 s Range: 0.5 to 10.0 sec., step: 1 DEFAULT MESSAGE TIMEOUT: 300 s Range: 10 to 900 sec., step: 1 AVERAGE MOTOR LOAD CALC.

The front panel RS232 has a fixed baud rate of 9600, a fixed data frame of 1 start, 8 data, and 1 stop bits with no parity. The front port is for local use only and responds regardless of the slave address programmed. This port may be connected to a personal computer running 469PC. The software can download and upload setpoint files as well as upgrade the 469 firmware. For RS485 communications, each 469 must have a unique address from 1 to 254. Address 0 is the broadcast address detected by all relays. Addresses do not have to be sequential but no two units can have the same address or errors will occur. Generally, each unit added to the link uses the next higher address starting at 1. Baud rates can be selected as 300, 1200, 2400, 4800, 9600, or 19200. The data frame is fixed at 1 start, 8 data, and 1 stop bits, while parity is optional. The computer RS485 port is a general purpose port for connection to a DCS, PLC, or PC. The auxiliary RS485 port may be used for redundancy or, it may be used to talk to auxiliary GE Power Management devices.
