MVME172P-644L工控备件模块
所遵循的程序细节基于欧洲最佳实践,并符合欧盟机械指令。即使这些要求不适用于您的安装,我们建议您遵循相同的步骤,但修改细节以符合相关法定要求或实践规范(例如ANSI、OSHA)。5.1危险的性质当操作员在危险附近时,该系统可通过隔离电源消除危险。需要采取额外措施来处理风险评估中确定的其他危险(例如零件喷射、热表面等)。这些措施可能包括固定防护装置、联锁防护装置、警告通知等。如果需要,请联系供应商获取更多信息。注:风险评估包含在EN 291-1中,并在EN 1050.5.2安全保护性质中详细说明。系统设计必须满足三个主要要求:1.如果有人能够进入危险区域,则必须停止机器。2.在接近人员能够进入危险区域之前,机器必须停止。3.不得轻易绕过系统。建议使用垫子系统,可在可能进入危险区域的整个区域进行存在感测。(参见图9中的示例)。
不建议将垫子系统用于其他用途,例如,仅用作周界门禁或机器启用装置。如果您正在考虑将垫子系统用于本手册未涵盖的任何应用,请联系供应商。图9 14 5.3环境和操作条件参考第4节中给出的规范和本节中的信息,确保不存在可能影响系统完整性的不利因素。5.3.1传感器垫乙烯基覆盖物的耐化学性–垫覆盖物的耐水性–优秀的乙醇–优秀的氯化钠–优秀的漂白–优秀的盐酸–优秀的硫酸–优秀的硝酸–优秀的乙酸–优秀的石油(汽油)–优秀的三氯乙烯–优秀的苯–较差的丙酮–较差一般来说,覆盖物具有优异的耐酸、耐碱和耐盐性。热酸和碱,以及浓酸和有机酸,对长时间接触有有害影响。该覆盖物对脂肪族溶剂具有较好的耐受性,对芳香族和氯化溶剂具有较好到较差的耐受性以及对酮和大多数酯的较差耐受性。注意:化学品的组合可能会产生不可预测的影响。在这种情况下,建议进行测试。若需要测试,供应商可提供小块乙烯基材料。5.3.2打滑/绊倒危险在大多数情况下,两种传感器垫模式都提供了防滑表面,但应保持无大量油脂、肥皂或凝胶沉积物。
The details of the procedures followed are based on European best practices and comply with the EU Machinery Directive. Even if these requirements do not apply to your installation, we recommend that you follow the same steps, but modify the details to comply with relevant statutory requirements or codes of practice (such as ANSI, OSHA). 5.1 Nature of the hazard When the operator is near the hazard, the system can eliminate the hazard by isolating the power supply. Additional measures are required to deal with other hazards identified in the risk assessment (e.g. part spray, hot surfaces, etc.). These measures may include fixed guards, interlocked guards, warning notices, etc. If necessary, please contact the supplier for more information. Note: Risk assessment is included in EN 291-1 and detailed in EN 1050.5.2 Nature of safety protection. The system design must meet three main requirements: 1. If someone can enter the dangerous area, the machine must be stopped. 2. The machine must be stopped before approaching personnel can enter the dangerous area. 3. Do not bypass the system easily. It is recommended to use a mat system that can sense presence throughout the area that may enter the hazardous area. (See the example in Figure 9).
It is not recommended to use the mat subsystem for other purposes, such as perimeter access control or machine activation. If you are considering using the mat subsystem for any application not covered in this manual, please contact the supplier. Figure 9 14 5.3 Environmental and operating conditions refer to the specifications given in Section 4 and the information in this section to ensure that there are no adverse factors that may affect system integrity. 5.3.1 Chemical resistance of sensor pad vinyl cover – water resistance of pad cover – excellent ethanol – excellent sodium chloride – excellent bleaching – excellent hydrochloric acid – excellent sulfuric acid – excellent nitric acid – excellent acetic acid – excellent petroleum (gasoline) – excellent trichloroethylene – excellent benzene – poor acetone – poor Generally speaking, the cover has excellent acid, alkali and salt resistance. Hot acid and alkali, as well as concentrated acid and organic acid, have harmful effects on long-term contact. The cover has good tolerance to aliphatic solvents, good to poor tolerance to aromatic and chlorinated solvents, and poor tolerance to ketones and most esters. Note: The combination of chemicals may have unpredictable effects. In this case, testing is recommended. If testing is required, the supplier can provide small pieces of vinyl material. 5.3.2 Slipping/tripping hazard In most cases, both sensor pad modes provide a non slip surface, but should be kept free of large amounts of grease, soap or gel deposits.
