MVME172P-642SE控制卡件
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）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。可接受小而規(guī)則的突起，如棋盤圖案。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。
If the straight rib side is uppermost, it is recommended that the ribs run across the hazard to give improved grip. 5.3.3 WEAR AND DAMAGE The mat outer surface can be damaged by impacts from sharp or heavy objects. After every such event the mat should be inspected for deformation or puncturing and replaced if necessary. Mats have been designed and tested to withstand one million operations in any one spot. In use, this number of operations in any single location should not be exceeded. Occasional heavy loads, (e.g. up to 3 tonne trucks) are unlikely to damage the mats but they should not be used on traffic through routes. 5.3.4 EXPLOSIVE ATMOSPHERES The system is not suitable for use in explosive atmospheres. 15 5.3.5 E.M.C. The mat system complies with the requirements of the European EMC Directive. Normal operation under interference conditions likely in industrial environments is assured and has been tested and certified. NOTE: Special measures may be required in the presence of abnormally high levels of E.M.I. e.g. near to welding or induction heating equipment or near radio transmitters/transceivers. 5.3.6 FLOOR The floor or mounting surface for the sensor mats must be flat, smooth and rigid, i.e. show no perceptible distortion under the heaviest load anticipated. Undulations, protrusions, large gaps or other irregularities will increase the sensitivity of the sensor mats and may result in intermittent unintended switching off (nuisance tripping). Fig 10 Floor condition for mats. Small and regular protrusions such as chequer plate pattern are acceptable. Skimmed concrete floors are ideal. If any doubt exists please contact the supplier. 5.3.7 CONTROL UNIT MOUNTING (refer to section 4 fig. 8) The control unit MUST NOT be mounted within the detection zone. If access to the control unit is required for manual reset or routine indicator observation, it should be mounted at an accessible position outside the protection zone which provides a good view of the hazard and protection zone. The reset actuator shall be situated outside the protection zone and in a position giving good visability of the hazard and protection zone. In other cases, the control unit may be mounted anywhere convenient outside the protection zone taking into account the access requirements for test and maintenance. The 440F-C4000D control unit should be mounted within an enclosure to a minimum of IP 54 (in accordance with EN 60529). NOTE: the Control unit is not suitable for direct exposure to high pressure cleaning. 5.4 MAT POSITIONING 5.4.1 FOR USE AS A COMBINED TRIP AND PRESENCE SENSING DEVICE The positioning of the mat edges is calculated as a horizontal distance from the hazard zone. Define the hazard zone as a volume, taking into account all the possible modes of the machine and all variations in size of the workpiece.
