MVME172-432A备件模块
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。遵守电气安全预防措施。8.5.1症状–如果垫子上没有任何东西，并且遵循了正确的重置程序，则无法启动机器。1.如果垫子控制单元上的MACHINE ENABLED LED（机器启用LED）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2A）。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。2.如果垫子控制单元上的MACHINE ENABLED LED（机器启用LED）熄灭，请采取以下措施：检查POWER LED（电源LED）是否点亮。如果不是，请检查垫子控制单元的电源。检查电源是否连接到适当的端子。检查控制单元中的主保险丝和辅助保险丝，必要时予以更换。确保一次保险丝和二次保险丝使用正确的保险丝值（500mA防浪涌）。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，请联系供应商。3.如果垫控制单元上的MACHINE ENABLED LED（机器启用LED）熄灭，POWER LED（电源LED）点亮。在带有接触器监控的双通道系统上，如果外部安全输出保险丝未熔断，则控制单元外部仍可能存在故障。
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. Observe electrical safety precautions. 8.5.1 Symptoms – If nothing is on the mat and the correct reset procedure is followed, the machine cannot be started. 1. If the MACHINE ENABLED LED on the mat control unit lights up, there may be a problem with the control system outside the machine or mat system. Check the external fuse in the safety output circuit of the control unit and replace it if necessary. Make sure to use the correct fuse value (max. 2A). 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 pad control unit and the final control element (contactor) of the machine. 2. If the MACHINE ENABLED LED on the mat control unit is off, take the following measures: Check whether the POWER LED is on. If not, check the power supply of the mat control unit. Check that the power supply is connected to the appropriate terminal. Check the main and auxiliary fuses in the control module and replace them if necessary. Ensure that the primary fuse and secondary fuse use the correct fuse value (500mA anti surge). Record the replacement in the inspection log. If the fuse blows immediately or needs to be replaced in advance, please contact the supplier. 3. If the MACHINE ENABLED LED on the pad control unit is off, the POWER LED is on. On a dual channel system with contactor monitoring, if the external safety output fuse is not blown, there may still be faults outside the control unit.
