MVME162-042工控备件模块
将检查和测试记录在书面日志中。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。断开控制单元端子和处至垫的电线。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欧姆。如果这些检查发现任何问题，则在纠正之前不得使用机器。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节。将检查和测试记录在书面日志中。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。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。遵守电气安全预防措施。症状如果垫子上没有任何东西，并且遵循正确的重置程序后，机器无法启动。如果垫子控制单元上的机器启用亮起，则机器或垫子系统外部的控制系统可能存在故障。检查控制单元安全输出线路中的外部保险丝，必要时予以更换。确保使用正确的保险丝值最大。将更换记录在检查日志中。如果保险丝立即熔断或需要提前更换，则垫控制单元的安全输出和机器的最终控制元件接触器之间的机器控制电路可能存在故障。如果垫子控制单元上的机器启用为开，请采取以下措施检查电源是否亮起。
Record inspections and tests in a written log. It is recommended to conduct comprehensive inspection and testing twice a year or contact the supplier after damage to obtain information on authorized testing services. The tests in the above are carried out 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 wire to the pad at the control unit terminal and. 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, that is, stand with both feet on the same uniform decoration between the two parts until all areas of the sensor mat are covered. The maximum resistance on the mat should not exceed ohms. If these checks reveal any problems, do not use the machine until it is corrected. Check whether the stopping performance of the machine has decreased compared with the performance used in the original safety distance calculation, see section. Record inspections and tests in a written log. The removal and disposal of the removal pad subsystem is the reverse of the installation procedure and does 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. The mat subsystem does not contain any hazardous materials that require special precautions. Fault finding Disconnect the prime mover before operating the mat control system with power. Observe electrical safety precautions. Symptoms If there is nothing on the mat and the correct reset procedure is followed, the machine cannot be started. If the machine enable on the mat control unit lights up, there may be a problem with the control system outside of the machine or mat system. Check the external fuse in the safety output circuit of the control unit and replace it if necessary. Ensure that the correct fuse value is used to the maximum. Record the replacement in the inspection log. If the fuse blows immediately or needs to be replaced in advance, there may be a problem with the machine control circuit between the safety output of the mat control unit and the final control element contactor of the machine. If the machine on the mat control unit is enabled as ON, take the following measures to check whether the power supply is on.
