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。检查控制装置中的主保险丝和辅助保险丝
Record the inspection and test in a written log. 37 8.4 DISMANTLING AND DISPOSAL Dismantling the mat system is the reverse of the installation procedure and no extra hazards are presented. ENSURE THAT THE MACHINE AND MAT SYSTEM POWER IS ISOLATED AND LOCKED OFF AT SOURCE BEFORE STARTING WORK. If the system is to be reconfigured or relocated, observe the handling precautions given in section 1. The mat system does not contain any hazardous materials which require special precautions for disposal. 8.5 FAULT FINDING Disconnect prime mover prior to working on mat control system with power applied. Observe electrical safety precautions. 8.5.1 Symptom – With no presence on the mat and after the correct reset procedure has been followed, the machine cannot be started. 1. If the MACHINE ENABLED LED on the mat control unit is ON there is a probable fault on the machine or its control system external to mat system. Check the external fuses in the control unit safety output wiring and replace if necessary. ENSURE THAT THE CORRECT VALUE OF FUSE IS USED (2A max). Record the replacement in the inspection log. If either fuse blows immediately or requires early replacement there is a probable fault in the machine control circuit between the safety output of the mat control unit and the machine’s final control element(s) (contactors). 2. If the MACHINE ENABLED LED on the mat control unit is OFF, take the following actions: Check that the the POWER LED is illuminated. If it is not, check the power supply to the mat control unit. Check that the power supply is connected to the appropriate terminals. Check the primary and secondary fuses in the control
