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(lái)說(shuō)，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(duì)長(zhǎng)時(shí)間接觸有有害影響。該覆蓋物對(duì)脂肪族溶劑具有較好的耐受性，對(duì)芳香族和氯化溶劑具有較好到較差的耐受性以及對(duì)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(cè)的影響。在這種情況下，建議進(jìn)行測(cè)試。若需要測(cè)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(wú)大量油脂、肥皂或凝膠沉積物。如果直肋側(cè)位于最上方，建議肋骨穿過(guò)危險(xiǎn)區(qū)域，以提高抓地力。5.3.3磨損和損壞墊子外表面可能因尖銳或重物的沖擊而損壞。每次此類事件后，應(yīng)檢查墊子是否變形或穿孔，必要時(shí)應(yīng)更換。墊子經(jīng)過(guò)設(shè)計(jì)和測(cè)試，可以在任何一個(gè)地方承受一百萬(wàn)次操作。在使用中，不應(yīng)超過(guò)任何單個(gè)位置的操作數(shù)。偶爾的重載（如3噸以下的卡車(chē)）不太可能損壞墊子，但不應(yīng)在通過(guò)路線的交通中使用。5.3.4爆炸性環(huán)境該系統(tǒng)不適用于爆炸性環(huán)境。15 5.3.5 E.M.C.墊子系統(tǒng)符合歐洲EMC指令的要求。確保了在工業(yè)環(huán)境中可能出現(xiàn)的干擾條件下的正常操作，并已通過(guò)測(cè)試和認(rèn)證。
注：當(dāng)存在異常高水平的電磁干擾時(shí)，可能需要采取特殊措施，例如靠近焊接或感應(yīng)加熱設(shè)備或靠近無(wú)線電發(fā)射機(jī)/收發(fā)器。5.3.6地板傳感器墊的地板或安裝表面必須平整、光滑且堅(jiān)硬，即在預(yù)計(jì)的最大載荷下不會(huì)出現(xiàn)明顯變形。起伏、凸起、大間隙或其他不規(guī)則現(xiàn)象將增加傳感器墊的靈敏度，并可能導(dǎo)致間歇性意外關(guān)閉（有害跳閘）。圖10墊子的地板狀況?？山邮苄《?guī)則的突起，如棋盤(pán)圖案。脫脂混凝土地板是理想的。如果有任何疑問(wèn)，請(qǐng)聯(lián)系供應(yīng)商。5.3.7控制單元安裝（參考圖8第4節(jié)）控制單元不得安裝在檢測(cè)區(qū)域內(nèi)。如果手動(dòng)復(fù)位或常規(guī)指示器觀察需要接近控制單元，則應(yīng)將其安裝在保護(hù)區(qū)外的可接近位置，以便能很好地觀察危險(xiǎn)和保護(hù)區(qū)。復(fù)位執(zhí)行機(jī)構(gòu)應(yīng)位于保護(hù)區(qū)外，且位置應(yīng)確保危險(xiǎn)和保護(hù)區(qū)清晰可見(jiàn)。在其他情況下，考慮到測(cè)試和維護(hù)的訪問(wèn)要求，控制單元可以安裝在保護(hù)區(qū)外任何方便的地方。440F-C4000D控制單元應(yīng)安裝在防護(hù)等級(jí)至少為IP 54的外殼內(nèi)（符合EN 60529）。注意：控制裝置不適合直接暴露于高壓清洗。5.4墊子定位5.4.1用作組合跳閘和存在感測(cè)裝置墊子邊緣的定位計(jì)算為與危險(xiǎn)區(qū)的水平距離。將危險(xiǎn)區(qū)域定義為一個(gè)體積，考慮到機(jī)器的所有可能模式和工件尺寸的所有變化。
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. If the straight rib side is at the top, it is recommended that the rib pass through the danger area to improve the grip. 5.3.3 Wear and damage The outer surface of the mat may be damaged by sharp or heavy impact. After each such event, the mat shall be checked for deformation or perforation and replaced if necessary. The cushion is designed and tested to withstand a million operations anywhere. In use, the operands of any single position shall not be exceeded. Occasional heavy loads (such as trucks under 3 tons) are unlikely to damage the mat, but should not be used in traffic passing the route. 5.3.4 Explosive environment The system is not applicable to explosive environment. 15 5.3.5 The E.M.C. mat subsystem complies with the requirements of the European EMC Directive. It ensures normal operation under possible interference conditions in industrial environment, and has passed the test and certification.
Note: When there is an abnormally high level of electromagnetic interference, special measures may be required, such as close to welding or induction heating equipment or close to radio transmitters/transceivers. 5.3.6 The floor or installation surface of the floor sensor pad must be flat, smooth and hard, that is, no obvious deformation will occur under the expected maximum load. Fluctuations, bulges, large gaps, or other irregularities will increase the sensitivity of the sensor pads and may cause intermittent accidental shutdowns (harmful trips). Fig. 10 Floor condition of mat. Small and regular protrusions, such as chessboard patterns, are acceptable. Degreasing concrete flooring is ideal. If you have any questions, please contact the supplier. 5.3.7 Installation of control unit (refer to Section 4 of Figure 8) The control unit shall not be installed in the detection area. If manual reset or conventional indicator observation requires access to the control unit, it should be installed in an accessible position outside the protected area so that the danger and protected area can be observed well. The reset actuator shall be located outside the protected area, and the location shall ensure that the danger and the protected area are clearly visible. In other cases, considering the access requirements for testing and maintenance, the control unit can be installed at any convenient place outside the protected area. The 440F-C4000D control unit shall be installed in an enclosure with a degree of protection of at least IP 54 (in accordance with EN 60529). Note: The control device is not suitable for direct exposure to high-pressure cleaning. 5.4 Cushion positioning 5.4.1 The positioning of the edge of the cushion used for combined tripping and presence sensing devices is calculated as the horizontal distance from the hazardous area. The hazardous area is defined as a volume, taking into account all possible modes of the machine and all changes in the size of the workpiece.
