PP845 3BSE042235R1控制器模块
IN AUTO RESET mode the output 'ON' signal is achieved solely by removal of the actuating force. For both modes, the safety contacts will always be 'OFF' (open) after the mat is actuated. Mode selection is covered in more detail in section 5. Individual sensor mats connect to each other and to the control unit via 4 wires. The control unit has cross monitored safety relays and it is possible to configure the unit so that an external contactor fault will be detected. Compliance with the requirements of EN 954-1 category 3 is achieved for the control unit regarding 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. Section 5 deals with interfacing in detail. The operating principle of the mat is shown in fig. 1. Fig. 1 When the mat is activated the non conductive compressible separators (shown black) compress into their recess allowing the two plates to make contact, giving all over sensitivity. The system is intended for the detection of adult persons with a weight of 35Kg or more. It is suitable for the detection of adults using walking aids (walking sticks or frames). THE SYSTEM IS NOT SUITABLE FOR THE DETECTION OF CHILDREN. THE SYSTEM MUST NOT BE USED WITH ANY ADDITIONAL COVERING ON THE MAT. MAT AT REST STEEL PLATES MOULDED VINYL MAT ACTIVATED 5 The vinyl outer surface of the mat is completely sealed to resist the ingress of liquids. It will resist bleaches, acids, salts and most industrial chemicals. Refer to section 5.3.1 for detailed guidance on chemical resistance. The system operates at 24V DC with restricted fault current. Damage to the mats or interconnecting wiring will not therefore generate any electrical shock hazard in normal circumstances在自动复位模式下，仅通过移除驱动力来实现输出“ON”信号。对于这两种模式，在启动垫子后，安全触点将始终处于“OFF”（断开）状态。第5节将更详细地介绍模式选择。各个传感器垫通过4根电线相互连接并连接到控制单元。控制单元具有交叉监控的安全继电器，可以配置该单元，以便检测到外部接触器故障。控制单元电气故障符合EN 954-1第3类的要求，机器控制系统的相关部分也能满足。垫子传感器符合EN 954-1第1类的要求。第5节详细介绍了接口。垫子的工作原理如图1所示。图1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，从而提供全部灵敏度。该系统旨在检测体重为35Kg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。该系统不适合检测儿童。该系统不得与垫上的任何额外覆盖物一起使用。垫在静止的钢板上模制乙烯基垫激活5。垫的乙烯基外表面完全密封，以防止液体进入。它能抵抗漂白剂、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。系统在24V DC下运行，故障电流受限。因此，在正常情况下，垫或互连线路的损坏不会产生任何电击危险。
