MVME172P-644L工控備件模塊
所遵循的程序細(xì)節(jié)基于歐洲最佳實(shí)踐，并符合歐盟機(jī)械指令。即使這些要求不適用于您的安裝，我們建議您遵循相同的步驟，但修改細(xì)節(jié)以符合相關(guān)法定要求或?qū)嵺`規(guī)范（例如ANSI、OSHA）。5.1危險(xiǎn)的性質(zhì)當(dāng)操作員在危險(xiǎn)附近時(shí)，該系統(tǒng)可通過隔離電源消除危險(xiǎn)。需要采取額外措施來處理風(fēng)險(xiǎn)評估中確定的其他危險(xiǎn)（例如零件噴射、熱表面等）。這些措施可能包括固定防護(hù)裝置、聯(lián)鎖防護(hù)裝置、警告通知等。如果需要，請聯(lián)系供應(yīng)商獲取更多信息。注：風(fēng)險(xiǎn)評估包含在EN 291-1中，并在EN 1050.5.2安全保護(hù)性質(zhì)中詳細(xì)說明。系統(tǒng)設(shè)計(jì)必須滿足三個(gè)主要要求：1.如果有人能夠進(jìn)入危險(xiǎn)區(qū)域，則必須停止機(jī)器。2.在接近人員能夠進(jìn)入危險(xiǎn)區(qū)域之前，機(jī)器必須停止。3.不得輕易繞過系統(tǒng)。建議使用墊子系統(tǒng)，可在可能進(jìn)入危險(xiǎn)區(qū)域的整個(gè)區(qū)域進(jìn)行存在感測。（參見圖9中的示例）。
不建議將墊子系統(tǒng)用于其他用途，例如，僅用作周界門禁或機(jī)器啟用裝置。如果您正在考慮將墊子系統(tǒng)用于本手冊未涵蓋的任何應(yīng)用，請聯(lián)系供應(yīng)商。圖9 14 5.3環(huán)境和操作條件參考第4節(jié)中給出的規(guī)范和本節(jié)中的信息，確保不存在可能影響系統(tǒng)完整性的不利因素。5.3.1傳感器墊乙烯基覆蓋物的耐化學(xué)性–墊覆蓋物的耐水性–優(yōu)秀的乙醇–優(yōu)秀的氯化鈉–優(yōu)秀的漂白–優(yōu)秀的鹽酸–優(yōu)秀的硫酸–優(yōu)秀的硝酸–優(yōu)秀的乙酸–優(yōu)秀的石油（汽油）–優(yōu)秀的三氯乙烯–優(yōu)秀的苯–較差的丙酮–較差一般來說，覆蓋物具有優(yōu)異的耐酸、耐堿和耐鹽性。熱酸和堿，以及濃酸和有機(jī)酸，對長時(shí)間接觸有有害影響。該覆蓋物對脂肪族溶劑具有較好的耐受性，對芳香族和氯化溶劑具有較好到較差的耐受性以及對酮和大多數(shù)酯的較差耐受性。注意：化學(xué)品的組合可能會(huì)產(chǎn)生不可預(yù)測的影響。在這種情況下，建議進(jìn)行測試。若需要測試，供應(yīng)商可提供小塊乙烯基材料。5.3.2打滑/絆倒危險(xiǎn)在大多數(shù)情況下，兩種傳感器墊模式都提供了防滑表面，但應(yīng)保持無大量油脂、肥皂或凝膠沉積物。
The details of the procedures followed are based on European best practices and comply with the EU Machinery Directive. Even if these requirements do not apply to your installation, we recommend that you follow the same steps, but modify the details to comply with relevant statutory requirements or codes of practice (such as ANSI, OSHA). 5.1 Nature of the hazard When the operator is near the hazard, the system can eliminate the hazard by isolating the power supply. Additional measures are required to deal with other hazards identified in the risk assessment (e.g. part spray, hot surfaces, etc.). These measures may include fixed guards, interlocked guards, warning notices, etc. If necessary, please contact the supplier for more information. Note: Risk assessment is included in EN 291-1 and detailed in EN 1050.5.2 Nature of safety protection. The system design must meet three main requirements: 1. If someone can enter the dangerous area, the machine must be stopped. 2. The machine must be stopped before approaching personnel can enter the dangerous area. 3. Do not bypass the system easily. It is recommended to use a mat system that can sense presence throughout the area that may enter the hazardous area. (See the example in Figure 9).
It is not recommended to use the mat subsystem for other purposes, such as perimeter access control or machine activation. If you are considering using the mat subsystem for any application not covered in this manual, please contact the supplier. Figure 9 14 5.3 Environmental and operating conditions refer to the specifications given in Section 4 and the information in this section to ensure that there are no adverse factors that may affect system integrity. 5.3.1 Chemical resistance of sensor pad vinyl cover – water resistance of pad cover – excellent ethanol – excellent sodium chloride – excellent bleaching – excellent hydrochloric acid – excellent sulfuric acid – excellent nitric acid – excellent acetic acid – excellent petroleum (gasoline) – excellent trichloroethylene – excellent benzene – poor acetone – poor Generally speaking, the cover has excellent acid, alkali and salt resistance. Hot acid and alkali, as well as concentrated acid and organic acid, have harmful effects on long-term contact. The cover has good tolerance to aliphatic solvents, good to poor tolerance to aromatic and chlorinated solvents, and poor tolerance to ketones and most esters. Note: The combination of chemicals may have unpredictable effects. In this case, testing is recommended. If testing is required, the supplier can provide small pieces of vinyl material. 5.3.2 Slipping/tripping hazard In most cases, both sensor pad modes provide a non slip surface, but should be kept free of large amounts of grease, soap or gel deposits.
