MVME172-303工控备件模块
遵守电气安全预防措施。8.1垫子清洁应定期清扫传感器垫子，以清除碎屑和其他材料等沉积物。如果需要清洗或用软管冲洗传感器垫以清洁或去除油脂等，则允许使用温水和清洁剂。不要使用溶剂。8.2常规检查和测试-（建议每周）停止机器。清洁传感器垫并使其干燥。检查垫的顶面是否损坏。乙烯盖的轻微划痕和磨损是可以接受的，但任何暴露金属板的损坏都必须立即处理。检查周边装饰件和联合装饰件是否开裂、断裂或变形，以及固定件是否牢固。必须立即更换损坏的零件。测试垫子操作。需要两个人，一人在垫子上行走，另一人观察控制单元。在使用手动复位模式的系统上，必须连续按下并释放复位按钮。在启动垫子之前，检查机器启用LED是否亮起，并在踏上垫子后立即熄灭。一个人应依次走过垫子的每个部分和每个连接部分（即双脚站在两个部分之间的同一个统一装饰上）。机器启用LED在整个时间内必须保持熄灭。离开垫子，操作复位按钮。检查机器启用LED是否点亮。启动机器，踩到垫子上，检查机器是否立即停止。检查所有固定防护装置和角板等是否到位、未损坏且固定牢固。如果这些检查发现任何问题，请在纠正之前不要使用机器。
将检查和测试记录在书面日志中。8.3全面检查和测试-（建议每年两次或在损坏后）联系供应商以获取授权测试服务的信息。由电气和机械工程方面的合格人员负责执行上述8.2中的测试。-隔离机器和垫系统的电源。遵守电气安全预防措施。-彻底检查垫组件有无机械损坏。-断开控制单元端子1、2、3和4处至垫的电线。-将两根白色导线连接到欧姆表的一个测试输入端，将两根黑色导线连接到另一个输入端。一个人应依次走过垫子的每个部分和每个连接部分（即，双脚站在两个部分之间的同一个统一装饰上），直到传感器垫的所有区域都被覆盖。垫上的最大电阻不应超过100欧姆。如果这些检查发现任何问题，请在纠正之前不要使用机器。检查机器的停止性能是否与原始安全距离计算中使用的性能相比有所下降（见第5节）。将检查和测试记录在书面日志中。37.8.4拆卸和处置拆卸垫子系统与安装程序相反，不会产生额外的危险。在开始工作之前，确保机器和垫子系统的电源被隔离并锁定在电源上。如果系统要重新配置或重新定位，请遵守第1节中给出的搬运预防措施。垫子系统不包含任何需要特殊预防措施处理的危险材料。8.5故障查找在使用电源对垫子控制系统进行操作之前，断开原动机。
Observe electrical safety precautions. 8.1 Cushion cleaning The sensor mat should be cleaned regularly to remove debris and other materials and other sediments. If it is necessary to clean or flush the sensor pad with hose to clean or remove grease, it is allowed to use warm water and detergent. Do not use solvents. 8.2 Routine Inspection and Testing - (Weekly is recommended) Stop the machine. Clean and dry the sensor pads. Check the top surface of the pad for damage. Slight scratches and wear on vinyl covers are acceptable, but any damage to exposed metal plates must be handled immediately. Check whether the peripheral trim and joint trim are cracked, broken or deformed, and whether the fixing parts are secure. Damaged parts must be replaced immediately. Test the mat operation. Two people are required, one to walk on the mat and the other to observe the control unit. On systems using manual reset mode, the reset button must be continuously pressed and released. Before starting the mat, check that the machine enable LED lights up and goes out immediately after stepping on the mat. A person should walk through each part of the mat and each connecting part in turn (i.e., stand with both feet on the same uniform decoration between the two parts). The machine enable LED must remain off for the entire time. Leave the mat and operate the reset button. Check that the machine enable LED is illuminated. Start the machine, step on the mat and check whether the machine stops immediately. Check whether all fixed protective devices and corner plates are in place, undamaged and firmly fixed. If these checks reveal any problems, do not use the machine until it has been corrected.
Record inspections and tests in a written log. 8.3 Overall inspection and testing - (recommended twice a year or after damage) Contact the supplier for information on authorized testing services. The tests in 8.2 above are performed by qualified personnel in electrical and mechanical engineering- Isolate the power supply of the machine and the cushion system. Observe electrical safety precautions- Thoroughly inspect the pad assembly for mechanical damage- Disconnect the wires from terminals 1, 2, 3 and 4 of the control unit to the pad- Connect two white leads to one test input of the ohmmeter and two black leads to the other input. A person should walk through each part of the mat and each connecting part in turn (i.e., stand with both feet on the same uniform trim between the two parts) until all areas of the sensor mat are covered. The maximum resistance on the mat should not exceed 100 ohms. If these checks reveal any problems, do not use the machine until it has been corrected. Check whether the stopping performance of the machine has decreased compared with the performance used in the original safety distance calculation (see Section 5). Record inspections and tests in a written log. 37.8.4 Removal and disposal The removal pad subsystem is contrary to the installation procedure and will not create additional hazards. Before starting work, make sure that the power supply of the machine and mat system is isolated and locked on the power supply. If the system is to be reconfigured or repositioned, follow the handling precautions given in Section 1. The mat subsystem does not contain any hazardous materials that require special precautions. 8.5 Fault finding Disconnect the prime mover before using the power supply to operate the mat control system.
