MVME172-303工控備件模塊
遵守電氣安全預(yù)防措施。8.1墊子清潔應(yīng)定期清掃傳感器墊子，以清除碎屑和其他材料等沉積物。如果需要清洗或用軟管沖洗傳感器墊以清潔或去除油脂等，則允許使用溫水和清潔劑。不要使用溶劑。8.2常規(guī)檢查和測試-（建議每周）停止機器。清潔傳感器墊并使其干燥。檢查墊的頂面是否損壞。乙烯蓋的輕微劃痕和磨損是可以接受的，但任何暴露金屬板的損壞都必須立即處理。檢查周邊裝飾件和聯(lián)合裝飾件是否開裂、斷裂或變形，以及固定件是否牢固。必須立即更換損壞的零件。測試墊子操作。需要兩個人，一人在墊子上行走，另一人觀察控制單元。在使用手動復(fù)位模式的系統(tǒng)上，必須連續(xù)按下并釋放復(fù)位按鈕。在啟動墊子之前，檢查機器啟用LED是否亮起，并在踏上墊子后立即熄滅。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）。機器啟用LED在整個時間內(nèi)必須保持熄滅。離開墊子，操作復(fù)位按鈕。檢查機器啟用LED是否點亮。啟動機器，踩到墊子上，檢查機器是否立即停止。檢查所有固定防護裝置和角板等是否到位、未損壞且固定牢固。如果這些檢查發(fā)現(xiàn)任何問題，請在糾正之前不要使用機器。
將檢查和測試記錄在書面日志中。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(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責(zé)執(zhí)行上述8.2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1、2、3和4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100歐姆。如果這些檢查發(fā)現(xiàn)任何問題，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（見第5節(jié)）。將檢查和測試記錄在書面日志中。37.8.4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1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。8.5故障查找在使用電源對墊子控制系統(tǒng)進行操作之前，斷開原動機。
Observe electrical safety precautions. 8.1 Cushion cleaning The sensor mat should be cleaned regularly to remove debris and other materials and other sediments. If it is necessary to clean or flush the sensor pad with hose to clean or remove grease, it is allowed to use warm water and detergent. Do not use solvents. 8.2 Routine Inspection and Testing - (Weekly is recommended) Stop the machine. Clean and dry the sensor pads. Check the top surface of the pad for damage. Slight scratches and wear on vinyl covers are acceptable, but any damage to exposed metal plates must be handled immediately. Check whether the peripheral trim and joint trim are cracked, broken or deformed, and whether the fixing parts are secure. Damaged parts must be replaced immediately. Test the mat operation. Two people are required, one to walk on the mat and the other to observe the control unit. On systems using manual reset mode, the reset button must be continuously pressed and released. Before starting the mat, check that the machine enable LED lights up and goes out immediately after stepping on the mat. 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 decoration between the two parts). The machine enable LED must remain off for the entire time. Leave the mat and operate the reset button. Check that the machine enable LED is illuminated. Start the machine, step on the mat and check whether the machine stops immediately. Check whether all fixed protective devices and corner plates are in place, undamaged and firmly fixed. 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.
