VMIVMEDR11W工控DCS系统备件
拆下印刷电路板
除非绝对必要，否则不要从控制柜上拆下印刷电路板（PCB）。如果必须从控制柜上拆下PCB，请遵循以下预防措施：•请勿触摸PCB的任何部分（边缘除外）。•不要用导电装置或手触摸电导体、连接器或部件。•更换PCB时，将新PCB放在塑料防静电保护袋中，直到准备好安装。从控制柜中取出旧PCB后，立即将其放入防静电保护袋中。注意——静电放电为了防止因处理不当而损坏电子部件，请阅读并遵守手册82715《电子控制装置、印刷电路板和模块的处理和保护指南》中的注意事项。负载共享模块手册26011 6第3章安装简介本节包含负载共享模块的一般安装说明。包括环境预防措施和位置考虑因素，以确定负载分配模块的最佳位置。其他信息包括开箱说明、电气连接和安装检查程序。
在处理负载共享模块
“静电放电意识”。拆下负载共享模块时要小心。检查装置是否有损坏迹象，如面板弯曲或凹陷、划痕、零件松动或断裂。通知托运人任何损坏。位置注意事项选择安装位置时应考虑以下要求：•冷却通风充足•维修和维修空间•防止直接暴露于水或易冷凝环境•防止高压或高电流设备，或产生电磁干扰的设备•防止过度振动•环境工作温度范围为–40至+70°C（–40至+158°F）请勿将负载分配模块安装在发动机上。图1-2是负载共享模块的外形图。将装置安装在尽可能靠近电子发动机控制装置的位置，但不要安装在发动机本身上。它可以安装在任何位置。为了保持符合CE标志要求，欧盟低压指令要求负载共享模块（LSM）安装在EN60529中定义的IP43外壳。必须限制合格人员进入负载共享模块。
Remove the printed circuit board
Do not remove the printed circuit board (PCB) from the control cabinet unless absolutely necessary. If the PCB must be removed from the control cabinet, please observe the following precautions: • Do not touch any part of the PCB (except the edges). • Do not touch electrical conductors, connectors or components with conductive devices or hands. • When replacing a PCB, place the new PCB in a plastic anti-static protective bag until it is ready for installation. Take out the old PCB from the control cabinet and put it into the anti-static protective bag immediately. Attention - Electrostatic discharge To prevent damage to electronic components due to improper handling, please read and follow the precautions in the manual 82715 "Guidelines for Handling and Protection of Electronic Control Devices, Printed Circuit Boards and Modules". Load sharing module manual 26011 6 Chapter 3 Installation introduction This section contains general installation instructions for the load sharing module. Include environmental precautions and location considerations to determine the optimal location of the load distribution module. Other information includes unpacking instructions, electrical connections, and installation inspection procedures.
Processing load sharing module
"Electrostatic discharge awareness". Take care when removing the load sharing module. Check the unit for signs of damage such as bent or dented panels, scratches, loose or broken parts. Notify the shipper of any damage. Location Precautions The following requirements should be considered when selecting the installation location: • Adequate cooling and ventilation • Maintenance and repair space • Prevent direct exposure to water or condensation prone environments • Prevent high-voltage or high current equipment, or equipment that generates electromagnetic interference • Prevent excessive vibration • Ambient operating temperature range is – 40 to+70 ° C (– 40 to+158 ° F) Do not install the load distribution module on the engine. Figure 1-2 is the outline drawing of the load sharing module. Install the unit as close to the electronic engine control as possible, but not on the engine itself. It can be installed anywhere. In order to maintain compliance with the CE mark, the EU low-voltage directive requires that the load sharing module (LSM) be installed in the IP43 enclosure defined in EN60529. Access to the load sharing module must be restricted to qualified personnel.
