269PLUS-DO-225-100P-HI-125VDC使用前面板上的12个键板完成编程

【功能描述】

269PLUS-DO-225-100P-HI-125VDC是GE Multilin 269 Plus电机保护系统系列中的电机保护继电器系统。该系统旨在与各种三相交流电动机一起使用。该系统通过电阻热检测器(rtd)和电流互感器(CTs)保护电机免受电气和热损伤。输入到控制的电源是80- 300 VDC或65-265 VAC和50-60 Hz。在120VAC/125 VDC时，最大功耗为20va和100ms。该设备的RTD传感器为100欧姆铂传感器。它们的显示精度为±2°C，设定值范围为0 - 200°C。传感器在3°C时有死区。传感器在0°C时也具有25%的电阻。

一旦系统被正确设置，它就可以被用户编程了。使用前面板上的12个键板完成编程。48个字符的字母数字液晶显示是确保系统正确编程的关键。在编程时，了解各个键执行的功能是很重要的。实际值键用于查找由系统确定的特定值。这些值可以包括相电流数据、计量数据和统计数据。前面板上的各种箭头键用于导航菜单以及调整参数。帮助键允许用户显示有关他们正在访问的特定参数或菜单的特定信息

The 269PLUS-DO-225-100P-HI-125VDC is a motor protection relay system in the GE Multilin 269 Plus motor protection system family. The system is designed for use with a variety of three-phase AC motors. The system protects the motor from electrical and thermal damage through resistance thermal detectors (RTDS) and current transformers (CTs). The power input to the control is 80-300 VDC or 65-265 VAC and 50-60 Hz. Maximum power consumption is 20va and 100ms at 120VAC/ 125VDC. The RTD sensor of the device is a 100 ohm platinum sensor. They have a display accuracy of ±2°C and a set point range of 0-200 °C. Sensor has dead zone at 3°C. The sensor also has a 25% resistance at 0°C.

Once the system is set up correctly, it can be programmed by the user. Programming is done using the 12 keyboards on the front panel. The 48-character alphanumeric LCD display is key to ensuring that the system is properly programmed. When programming, it is important to understand the functions performed by the individual keys. The actual value key is used to find a specific value determined by the system. These values can include phase current data, metering data, and statistics. Various arrow keys on the front panel are used to navigate menus and adjust parameters. The help key allows users to display specific information about a particular parameter or menu they are accessing
