手動復(fù)位通過按下和釋放蓋上安裝的控制單元復(fù)位按鈕或遠程安裝的按鈕來實現(xiàn)。在通電或斷電后以及隨后恢復(fù)電源后，輸出將“關(guān)閉”，直到收到復(fù)位信號，即使墊子未啟動。在自動復(fù)位模式下，僅通過移除驅(qū)動力來實現(xiàn)輸出“ON”信號。對于這兩種模式，在啟動墊子后，安全觸點將始終處于“OFF”（斷開）狀態(tài)。第5節(jié)將更詳細地介紹模式選擇。各個傳感器墊通過4根電線相互連接并連接到控制單元?？刂茊卧哂薪徊姹O(jiān)控的安全繼電器，可以配置該單元，以便檢測到外部接觸器故障?？刂茊卧姎夤收戏螮N 954-1第3類的要求，機器控制系統(tǒng)的相關(guān)部分也能滿足。墊子傳感器符合EN 954-1第1類的要求。第5節(jié)詳細介紹了接口。墊子的工作原理如圖1所示。圖1當(dāng)墊子被激活時，非導(dǎo)電可壓縮隔板（顯示為黑色）壓縮到其凹槽中，允許兩個板接觸，從而提供全部靈敏度。該系統(tǒng)旨在檢測體重為35Kg或以上的成年人。它適用于檢測使用助行器（手杖或框架）的成年人。該系統(tǒng)不適合檢測兒童。
該系統(tǒng)不得與墊上的任何額外覆蓋物一起使用。墊在靜止的鋼板上模制乙烯基墊激活5。墊的乙烯基外表面完全密封，以防止液體進入。它能抵抗漂白劑、酸、鹽和大多數(shù)工業(yè)化學(xué)品。有關(guān)耐化學(xué)性的詳細指南，請參閱第5.3.1節(jié)。系統(tǒng)在24V DC下運行，故障電流受限。因此，在正常情況下，墊或互連線路的損壞不會產(chǎn)生任何電擊危險。圖2基本系統(tǒng)和連接（用兩個接觸器顯示）。440F-C4000P和440F-C400S。注：復(fù)位按鈕的位置與440F-C4000S上的位置不同。110/230V交流電源端子24 V交流/直流電源端子手動復(fù)位/自動復(fù)位開關(guān)輔助保險絲500mA主保險絲500mA 110/230V交流電選擇開關(guān)蓋裝復(fù)位按鈕控制單元N/O PB R IND MC MC 31 32 13 14 23 24 1 2 3 4–ve+ve N L A M 230 110 LED指示燈遠程復(fù)位端子遠程復(fù)位指示端子接觸器監(jiān)控端子輔助端子安全輸出端子墊連接端子機器啟用綠色自動復(fù)位模式綠色手動復(fù)位模式綠色電源綠色傳感器墊接觸器控制電源無電壓輔助。如果需要，觸點用于指示遠程復(fù)位按鈕如果需要，L1 L2 L3 K1 K2 6圖3基本系統(tǒng)和連接（顯示為兩個觸點）。
Manual reset is achieved by pressing and releasing the control unit reset button installed on the cover or the remote installed button. After power on or power off and subsequent power restoration, the output will "turn off" until a reset signal is received, even if the mat is not started. In the automatic reset mode, the "ON" signal is output only by removing the driving force. For these two modes, after starting the mat, the safety contact will always be in the "OFF" state. Section 5 will cover mode selection in more detail. The sensor pads are connected to each other and to the control unit via 4 wires. The control unit has a cross monitored safety relay, which can be configured to detect external contactor faults. The electrical failure of the control unit meets the requirements of EN 954-1 Class 3, and the relevant parts of the machine control system can also meet the requirements. The cushion sensor complies with the requirements of EN 954-1 Class 1. Section 5 describes the interface in detail. The working principle of the mat is shown in Figure 1. Fig. 1 When the mat is activated, the non-conductive compressible partition (shown in black) is compressed into its groove, allowing two plates to contact, thus providing full sensitivity. The system is designed to detect adults weighing 35Kg or more. It is suitable for detecting adults using walking aids (walking sticks or frames). The system is not suitable for detecting children.
The system shall not be used with any additional covering on the mat. The pad is molded onto a stationary steel plate and the vinyl pad is activated by 5. The vinyl outer surface of the gasket is completely sealed to prevent liquid ingress. It is resistant to bleaching agents, acids, salts and most industrial chemicals. Refer to Section 5.3.1 for detailed guidance on chemical resistance. The system operates at 24V DC and the fault current is limited. Therefore, under normal conditions, damage to the mat or interconnecting circuit does not create any electrical shock hazard.
