MVME172-432A備件模塊
如果這些檢查發(fā)現任何問(wèn)題，請在糾正之前不要使用機器。將檢查和測試記錄在書(shū)面日志中。8.3全面檢查和測試-（建議每年兩次或在損壞后）聯(lián)系供應商以獲取授權測試服務(wù)的信息。由電氣和機械工程方面的合格人員負責執行上述8.2中的測試。-隔離機器和墊系統的電源。遵守電氣安全預防措施。-徹底檢查墊組件有無(wú)機械損壞。-斷開(kāi)控制單元端子1、2、3和4處至墊的電線(xiàn)。-將兩根白色導線(xiàn)連接到歐姆表的一個(gè)測試輸入端，將兩根黑色導線(xiàn)連接到另一個(gè)輸入端。一個(gè)人應依次走過(guò)墊子的每個(gè)部分和每個(gè)連接部分（即，雙腳站在兩個(gè)部分之間的同一個(gè)統一裝飾上），直到傳感器墊的所有區域都被覆蓋。墊上的最大電阻不應超過(guò)100歐姆。如果這些檢查發(fā)現任何問(wèn)題，請在糾正之前不要使用機器。檢查機器的停止性能是否與原始安全距離計算中使用的性能相比有所下降（見(jiàn)第5節）。將檢查和測試記錄在書(shū)面日志中。37.8.4拆卸和處置拆卸墊子系統與安裝程序相反，不會(huì )產(chǎn)生額外的危險。在開(kāi)始工作之前，確保機器和墊子系統的電源被隔離并鎖定在電源上。如果系統要重新配置或重新定位，請遵守第1節中給出的搬運預防措施。
墊子系統不包含任何需要特殊預防措施處理的危險材料。8.5故障查找在使用電源對墊子控制系統進(jìn)行操作之前，斷開(kāi)原動(dòng)機。遵守電氣安全預防措施。8.5.1癥狀–如果墊子上沒(méi)有任何東西，并且遵循了正確的重置程序，則無(wú)法啟動(dòng)機器。1.如果墊子控制單元上的MACHINE ENABLED LED（機器啟用LED）亮起，則機器或墊子系統外部的控制系統可能存在故障。檢查控制單元安全輸出線(xiàn)路中的外部保險絲，必要時(shí)予以更換。確保使用正確的保險絲值（最大2A）。將更換記錄在檢查日志中。如果保險絲立即熔斷或需要提前更換，則墊控制單元的安全輸出和機器的最終控制元件（接觸器）之間的機器控制電路可能存在故障。2.如果墊子控制單元上的MACHINE ENABLED LED（機器啟用LED）熄滅，請采取以下措施：檢查POWER LED（電源LED）是否點(diǎn)亮。如果不是，請檢查墊子控制單元的電源。檢查電源是否連接到適當的端子。檢查控制單元中的主保險絲和輔助保險絲，必要時(shí)予以更換。確保一次保險絲和二次保險絲使用正確的保險絲值（500mA防浪涌）。將更換記錄在檢查日志中。如果保險絲立即熔斷或需要提前更換，請聯(lián)系供應商。3.如果墊控制單元上的MACHINE ENABLED LED（機器啟用LED）熄滅，POWER LED（電源LED）點(diǎn)亮。在帶有接觸器監控的雙通道系統上，如果外部安全輸出保險絲未熔斷，則控制單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.
