MVME172-433A自动化模块备件
按下重置按钮：机器启用的LED在垫子运行时亮起：机器启用LED熄灭垫：机器启用发光二极管仍熄灭按下重置按钮，机器启用LED亮起在故障情况下，机器启用的灯熄灭，在故障排除之前不允许重置。在故障状态下，如果存在垫子故障，一个或多个垫子状态LED将点亮。在开路或短路情况下，LED将亮起红色。如果存在故障，且MAT STATUS LED均未亮起，则说明控制单元故障。6.5检查安全功能6.5.1单通道系统（参见图15和17第5节）模拟正常操作。站在垫子上启动垫子，并检查主接触器是否立即脱落。检查任何其他与安全相关的停止功能，如制动器、离合器接触器是否按预期运行。6.5.2双通道系统（见图16和18第5节）1.模拟正常操作。站在垫子上启动垫子，并立即检查两个最终接触器是否脱落。检查任何其他与安全相关的停止功能，如制动器/离合器接触器是否按预期运行。
2.隔离电源，然后通过将端子块6处的端子13和14短路来安装临时故障（图26或27）。3.恢复电源并启动传感器垫，并检查其中一个最终接触器是否立即断开，以及与该通道相关的任何其他停止功能是否按预期运行。4.检查控制单元不会复位5.隔离电源并排除临时故障。恢复电源并检查垫子系统是否正常工作。采取相同的电气安全预防措施，在端子块6处的端子23和24之间临时短路，重复测试（图26或27）。6.再次检查控制单元不会复位7.排除临时故障，检查垫系统是否正常工作。35 6.5.3所有系统类型1.进行所需的任何其他测试，以确认安全相关控制系统符合EN 954-1规定的类别要求，并按预期工作。2.检查与受垫系统安装影响的机器电路相关的任何其他安全功能。这些测试应有现有程序。3.在电源处隔离机器电源。4.重新连接机器控制系统提供的任何自动复位功能。5.将机器原动机重新连接至最终接触器。6.固定所有盖子和门。6.6功能检查恢复机器电源。检查：-1。在重置垫子控制单元之前，机器无法开始操作。
Press the reset button: the machine enabled LED lights up when the mat is running: the machine enabled LED goes out Pad: the machine enabled LED is still off Press the reset button, the machine enabled LED lights up In case of a fault, the machine enabled lamp goes out, and resetting is not allowed until the fault is eliminated. In the fault state, if there is a mat fault, one or more mat status LEDs will illuminate. In case of open circuit or short circuit, the LED will light red. If there is a fault and the MAT STATUS LED is not lit, the control unit is faulty. 6.5 Checking safety functions 6.5.1 Single channel system (see Figure 15 and Section 5 of 17) simulates normal operation. Stand on the mat and start the mat, and check whether the main contactor falls off immediately. Check whether any other safety related stop functions, such as brake and clutch contactor operate as expected. 6.5.2 Dual channel system (see Figure 16 and 18, Section 5) 1. Simulate normal operation. Stand on the mat and start the mat, and immediately check whether the two final contactors fall off. Check that any other safety related stop functions, such as brake/clutch contactors, operate as expected.
2. Isolate the power supply, and then install a temporary fault by shorting terminals 13 and 14 at terminal block 6 (Figure 26 or 27). 3. Restore the power supply and start the sensor pad, and check that one of the final contactors is immediately disconnected, and that any other stop functions associated with this channel operate as expected. 4. Check that the control unit will not reset 5. Isolate the power supply and eliminate the temporary fault. Restore the power supply and check whether the mat subsystem works normally. Take the same electrical safety precautions, temporarily short circuit between terminals 23 and 24 at terminal block 6, and repeat the test (Figure 26 or 27). 6. Check again that the control unit will not reset 7. Remove the temporary fault and check whether the cushion system works normally. 35 6.5.3 All system types 1. Carry out any other tests required to confirm that the safety related control system conforms to the category requirements specified in EN 954-1 and works as expected. 2. Check any other safety functions related to the machine circuit affected by the installation of the mat system. These tests should have existing procedures. 3. Isolate the machine power at the power supply. 4. Reconnect any automatic reset functions provided by the machine control system. 5. Reconnect the machine prime mover to the final contactor. 6. Secure all covers and doors. 6.6 Function check to restore the machine power. Check: - 1. The machine cannot start operation until the mat control unit is reset.
