t至控制单元。任一接线通道中的单一故障将导致Allen-Bradley Guardmaster控制单元锁定安全输出，直到故障得到纠正并重置控制单元。检查系统中的所有连接导线是否正确配置且未损坏，两个接触器是否正常工作。排除所有故障，如果处于手动复位模式，则按下并释放控制单元复位按钮。4.如果问题未得到解决，请与供应商联系。8.5.2症状机器不会停止或可以在垫子上出现时启动。1.如果垫子上出现，Allen-Bradley Guardmaster控制单元上的机器启用LED是否亮起？2.如果机器启用LED未亮起，则AllenBradley Guardmaster系统外部的机器或其控制系统可能存在故障。在排除和测试故障之前，不得使用机器。3.如果机器启用LED亮起。不允许使用机器，并立即联系供应商。8.5.3症状机器在传感器垫上不存在的情况下意外停止，但可以在踩下垫后重新启动（并在手动复位模式下复位）。1.检查所有指示灯是否正常工作。如果是这样的话，问题很可能是由某个值和持续时间的供电下降引起的。这可能会导致控制单元中的一个内部继电器断开，从而模拟故障状况。这是极不可能发生的情况，不需要采取补救措施。在问题持续存在的异常情况下，可能需要采取措施确保Allen-Bradley Guardmaster系统的供电更加顺畅。8.6维修在操作Allen-Bradley Guardmaster系统或机器控制系统之前，隔离机器和Allen-BradleyGuardmaster系统的电源。遵守电气安全预防措施。用户维修仅限于更换新的Allen-Bradley Guardmaster系统部件。如果出现问题，应将装置退还给供应商。应使用推荐的对接拼接接头对连接线进行任何维修。篡改零部件将使保修失效。对于特殊尺寸的传感器垫，请参阅标签上打印的型号。更换任何零件后，必须进行8.2所示的检查和测试，并特别注意更换的零件。请勿使用机器。注意：440F MatGuard™ Mat Manager用户手册第8节-维护38罗克韦尔自动化出版物95302194/EO:0240
o the control unit. A single fault in either wiring channel will cause the Allen-Bradley Guardmaster control unit to lock off the safety outputs until the fault is rectified and the control unit is reset. Check that all connecting wiring in the system is configured correctly and has not been damaged and that both contactors are functioning correctly. Rectify any faults and if in manual reset mode press and release the control unit reset button. 4. If the problem is not resolved please contact your supplier. 8.5.2 Symptom Machine does not stop or can be started with presence on the mat. 1. With presence on the mat, is the MACHINE ENABLED LED illuminated on the Allen-Bradley Guardmaster control unit? 2. If the MACHINE ENABLED LED is not illuminated there is a probable fault on the machine or its control system external to the AllenBradley Guardmaster system. DO NOT ALLOW USE OF THE MACHINE UNTIL THE FAULT HAS BEEN RECTIFIED AND TESTED. 3. If the MACHINE ENABLED LED is illuminated. DO NOT ALLOW USE OF THE MACHINE AND CONTACT THE SUPPLIER IMMEDIATELY. 8.5.3 Symptom Machine stops unexpectedly with no presence on the sensor mat but can be restarted after stepping on and off the mat (and resetting when in manual reset mode). 1. Check that all indicator lights are operating correctly. If they are, the problem is likely to be caused by a dip in supply power of a certain value and duration. This can cause one of the internal relays in the control unit to drop out, thus simulating a fault condition. This is a very unlikely occurrence and no remedial action is required. In the unusual event of the problem persisting, measures may be required to ensure a smoother power supply to the Allen-Bradley Guardmaster system. 8.6 Repair Prior to working on Allen-Bradley Guardmaster system or machine control system, isolate power source to the machine and AllenBradley Guardmaster system. Observe electrical safety precautions. User repairs are limited to replacement by new Allen-Bradley Guardmaster system parts. In the event of problems, the units should be returned to the supplier. Any repairs to the connecting wires should be made using the recommended butt splice connectors. TAMPERING WITH COMPONENT PARTS WILL INVALIDATE WARRANTY. For special sized sensor mats, refer to the model no. printed on the label. After replacing any parts the inspection and test shown at 8.2 must be carried out with special attention given to those parts replaced. Do not allow the use of the machine.
