RSER200-4模拟量输入模块
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规范第4节中给出的规范和本节中的信息确保不存在可能危及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。如果直肋侧位于最上方，建议肋骨穿过危险区域，以提高抓地力。5.3.3磨损和损坏垫子外表面可能因尖锐或重物的冲击而损坏。每次此类事件后，应检查垫子是否变形或穿孔，必要时应更换。垫子经过设计和测试，可以在任何一个地方承受一百万次操作。在使用中，不应超过任何单个位置的操作数。偶尔的重载（如3吨以下的卡车）不太可能损坏垫子，但不应在通过路线的交通中使用。5.3.4爆炸性环境该系统不适用于爆炸性环境。15 5.3.5 E.M.C.垫子系统符合欧洲EMC指令的要求。确保了在工业环境中可能出现的干扰条件下的正常操作，并已通过测试和认证。注：当存在异常高水平的电磁干扰时，可能需要采取特殊措施，例如靠近焊接或感应加热设备或靠近无线电发射机/收发器。5.3.6地板传感器垫的地板或安装表面必须平整、光滑且坚硬，即在预计的最大载荷下不会出现明显变形。
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 of the specification and the information in this section to ensure that there are no adverse factors that could endanger the integrity of the system. 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. If the straight rib side is at the top, it is recommended that the rib pass through the danger area to improve the grip. 5.3.3 Wear and damage The outer surface of the mat may be damaged by sharp or heavy impact. After each such event, the mat shall be checked for deformation or perforation and replaced if necessary. The cushion is designed and tested to withstand a million operations anywhere. In use, the operands of any single position shall not be exceeded. Occasional heavy loads (such as trucks under 3 tons) are unlikely to damage the mat, but should not be used in traffic passing the route. 5.3.4 Explosive environment The system is not applicable to explosive environment. 15 5.3.5 The E.M.C. mat subsystem complies with the requirements of the European EMC Directive. It ensures normal operation under possible interference conditions in industrial environment, and has passed the test and certification. Note: When there is an abnormally high level of electromagnetic interference, special measures may be required, such as close to welding or induction heating equipment or close to radio transmitters/transceivers. 5.3.6 The floor or installation surface of the floor sensor pad must be flat, smooth and hard, that is, no obvious deformation will occur under the expected maximum load.
