MVME162-042工控備件模塊
將檢查和測試記錄在書面日志中。全面檢查和測試建議每年兩次或在損壞后聯(lián)系供應(yīng)商以獲取授權(quán)測試服務(wù)的信息。由電氣和機械工程方面的合格人員負(fù)責(zé)執(zhí)行上述中的測試。隔離機器和墊系統(tǒng)的電源。遵守電氣安全預(yù)防措施。徹底檢查墊組件有無機械損壞。斷開控制單元端子和處至墊的電線。將兩根白色導(dǎo)線連接到歐姆表的一個測試輸入端，將兩根黑色導(dǎo)線連接到另一個輸入端。一個人應(yīng)依次走過墊子的每個部分和每個連接部分即，雙腳站在兩個部分之間的同一個統(tǒng)一裝飾上，直到傳感器墊的所有區(qū)域都被覆蓋。墊上的最大電阻不應(yīng)超過歐姆。如果這些檢查發(fā)現(xiàn)任何問題，則在糾正之前不得使用機器。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第節(jié)。將檢查和測試記錄在書面日志中。拆卸和處置拆卸墊子系統(tǒng)與安裝程序相反，不會產(chǎn)生額外的危險。在開始工作之前，確保機器和墊子系統(tǒng)的電源被隔離并鎖定在電源上。如果系統(tǒng)要重新配置或重新定位，請遵守第節(jié)中給出的搬運預(yù)防措施。墊子系統(tǒng)不包含任何需要特殊預(yù)防措施處理的危險材料。故障查找在使用電源對墊子控制系統(tǒng)進(jìn)行操作之前，斷開原動機。遵守電氣安全預(yù)防措施。癥狀如果墊子上沒有任何東西，并且遵循正確的重置程序后，機器無法啟動。如果墊子控制單元上的機器啟用亮起，則機器或墊子系統(tǒng)外部的控制系統(tǒng)可能存在故障。檢查控制單元安全輸出線路中的外部保險絲，必要時予以更換。確保使用正確的保險絲值最大。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。如果墊子控制單元上的機器啟用為開，請采取以下措施檢查電源是否亮起。
Record inspections and tests in a written log. It is recommended to conduct comprehensive inspection and testing twice a year or contact the supplier after damage to obtain information on authorized testing services. The tests in the above are carried out 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 wire to the pad at the control unit terminal and. 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, that is, stand with both feet on the same uniform decoration between the two parts until all areas of the sensor mat are covered. The maximum resistance on the mat should not exceed ohms. If these checks reveal any problems, do not use the machine until it is corrected. Check whether the stopping performance of the machine has decreased compared with the performance used in the original safety distance calculation, see section. Record inspections and tests in a written log. The removal and disposal of the removal pad subsystem is the reverse of the installation procedure and does 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. The mat subsystem does not contain any hazardous materials that require special precautions. Fault finding Disconnect the prime mover before operating the mat control system with power. Observe electrical safety precautions. Symptoms If there is nothing on the mat and the correct reset procedure is followed, the machine cannot be started. If the machine enable on the mat control unit lights up, there may be a problem with the control system outside of the machine or mat system. Check the external fuse in the safety output circuit of the control unit and replace it if necessary. Ensure that the correct fuse value is used to the maximum. 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 mat control unit and the final control element contactor of the machine. If the machine on the mat control unit is enabled as ON, take the following measures to check whether the power supply is on.
