PFTL301E0.5kN系统模块备件
垫子的工作原理如图2所示。图2当垫子被激活时，非导电可压缩隔板（显示为黑色）压缩到其凹槽中，允许两个板接触。Allen-Bradley Guardmaster系统用于检测体重为30公斤（66磅）或以上的成年人。它适用于检测使用助行器（手杖或框架）的成年人。垫子的乙烯基外表面被密封以防止液体进入，防护等级为IP67。它可以抵抗漂白剂、酸、盐和大多数工业化学品。有关耐化学性的详细指南，请参阅第5.3.1节。Allen-Bradley Guardmaster垫子传感器有两种不同的肋骨模式，如图3所示。任何一种模式都可以用作上表面。方格图案在各个方向都能提供最佳抓地力。直肋模式更易于软管/冲洗，更适合在肮脏或卫生敏感的应用中使用。图3控制装置符合EN 954-1第3类、ISO13849第PLd和IEC62061第SIL2类关于可靠性和电气故障的要求，并且可满足机器控制系统相关部分的要求。垫子传感器符合EN 954-1第1类的要求。检测区域内没有“死区”。第3节-应用重要的是，保护系统的类型适合其预期应用。对机械或过程进行风险评估的文件化过程将揭示危险的身份和性质以及其他相关信息。然后，应将防护系统的特性与风险评估结果进行比较，以确定是否可以将风险降低到可接受的水平。在某些应用中，为了达到可接受的风险水平，可能需要组合使用多种类型的防护系统。钢板模压乙烯基静止垫激活网纹肋图案直肋图案罗克韦尔自动化出版物95302194/EO:0240发行号：8 7 440F MatGuard™ Mat Manager用户手册第3节-应用•Allen-Bradley Guardmaster系统设计用于通过感应人员在机器周围的地板区域和其他类似危险来保护人员。•Allen-Bradley Guardmaster系统只能在给定的规范限制范围内使用
The operating principle of the mat is shown in Figure 2. Figure 2 When the mat is activated the non-conductive compressible separators (shown black) compress into their recess allowing the two plates to make contact. The Allen-Bradley Guardmaster system is intended for the detection of adult persons with a weight of 30 Kg (66 lbs) or more. It is suitable for the detection of adults using walking aids (walking sticks or frames). The vinyl outer surface of the mat is sealed to resist the ingress of liquids and rated to IP67. It will resist bleaches, acids, salts and most industrial chemicals. Refer to section 5.3.1 for detailed guidance on chemical resistance. The Allen-Bradley Guardmaster mat sensors have two different rib patterns as shown in Figure 3. Either pattern may be used as the upper surface. The chequer pattern gives the best grip in all directions. The straight rib pattern is easier to hose/washdown and is more suitable for use in dirty or hygiene sensitive applications. Figure 3 Compliance for the control unit is achieved with the requirements of category 3 per EN 954-1, PLd per ISO13849 and SIL2 per IEC62061 regarding reliability and electrical faults and can be met for the associated part of the machine control system. Compliance with the requirements of EN 954-1 category 1 is achieved for the mat sensors. There are no “dead zones” within the detection zone. Section 3 - Applications It is important that the type of safeguarding system is suitable for the application for which it is intended. A documented process of risk assessment of the machinery or process will reveal the identity and nature of the hazards together with other relevant information. The characteristics of the safeguarding system should then be compared with the results of the risk assessment to determine whether the risk can be reduced to an acceptable level. On some applications the combined use of more than one type of safeguarding system may be necessary to achieve an acceptable level of risk.
