测试和维护的访问要求。440F-C4000D控制单元应安装在防护等级至少为IP 54的外壳内（符合EN 60529）。注意：控制装置不适合直接暴露于高压清洗。5.4垫子定位5.4.1用作组合跳闸和存在感测装置垫子边缘的定位计算为与危险区的水平距离。将危险区域定义为一个体积，考虑到机器的所有可能模式和工件尺寸的所有变化。必须记录危险区域的尺寸和位置以及使用的假设，以便检查防护措施的充分性。如果其他防护措施与垫子系统一起使用，可能会影响确保盖子和格栅与地板表面齐平。无松散碎屑或突起。传感器垫不得下垂或起伏。没有锋利的边缘。传感器垫传感器垫16对垫的尺寸和位置的要求，如图11所示。图11。注意：固定防护装置应符合EN 953、EN 294和EN 811的要求。首先，确定需要穿过垫系统无障碍进入危险区域的路线。考虑所有日常访问需求，如产品检查、机器检查和调整、刀具更换和清除堵塞。还应考虑过程的视觉观察。在干预过程中，考虑机器附近人员和辅助设备的空间要求。安全距离计算对于使用垫子系统作为组合跳闸和存在感测系统的应用，应根据EN999进行计算。图12的流程图显示了基本步骤。注：如果机器的设计符合该机器的现有协调欧洲“C”型标准，该标准给出了具体公式或最小距离，则应优先使用EN 999中给出的公式。传感器垫危险传感器垫固定防护延伸固定防护箭头显示通道17图。
the access requirements for test and maintenance. The 440F-C4000D control unit should be mounted within an enclosure to a minimum of IP 54 (in accordance with EN 60529). NOTE: the Control unit is not suitable for direct exposure to high pressure cleaning. 5.4 MAT POSITIONING 5.4.1 FOR USE AS A COMBINED TRIP AND PRESENCE SENSING DEVICE The positioning of the mat edges is calculated as a horizontal distance from the hazard zone. Define the hazard zone as a volume, taking into account all the possible modes of the machine and all variations in size of the workpiece. It is essential to record the dimensions and position of the hazard zone and the assumptions used, so that the adequacy of the safeguarding can be checked. If other safeguarding measures are used in conjunction with the mat system they may affect the Ensure that covers and gratings are flush with floor surface. No loose debris or protrusions. Sensor mat must not sag or undulate. No sharp edges. SENSOR MAT SENSOR MAT 16 requirements for the size and positioning of the mats as shown in Fig. 11. Fig. 11. NOTE: Fixed guarding should meet the requirements of EN 953, EN 294 & EN 811. Firstly, ascertain the route(s) where unobstructed access to the hazard zone is required across the mat system. Take into account all the routine needs for access, such as product inspection, machine inspection and adjustment, tool changes & clearing blockages. Consider also visual observation of the process. Take into account the space requirements of persons and ancillary equipment close to the machine during interventions. SAFETY DISTANCE CALCULATIONS For applications using the mat system as a combined trip and presence sensing system these should be done in accordance with EN999. The flow chart at fig. 12 shows the essential steps. NOTE: If the machine is designed in conformity with an existing harmonised European “C”: type standard for that machine which gives specific formulae or minimum distances, then these should be used in preference to those given in EN 999.
