第1節-儲存和搬運1.1儲存控制裝置和墊傳感器應儲存在-40°C至+70°C的溫度范圍內。墊子傳感器應垂直存放。1.2搬運和運輸控制裝置和墊傳感器應在-40°C至+70°C的溫度范圍內運輸。應使用原始包裝或類(lèi)似包裝，必要時(shí)應加固，以防止損壞和彎曲。始終小心打開(kāi)包裝，避免被刀具等損壞。當傳感器墊移動(dòng)到位時(shí)，切勿通過(guò)其連接線(xiàn)拉動(dòng)或提起傳感器。對于較大的傳感器墊，需要兩個(gè)人才能安全起吊并防止傳感器墊因過(guò)度彎曲而損壞。4第2節-系統描述系統包括一個(gè)或多個(gè)互連的壓敏墊和一個(gè)控制單元。檢測區域內沒(méi)有“死區”。單個(gè)傳感器墊部分有矩形標準尺寸，也有特殊切割形狀，最大尺寸為最大標準墊。所有傳感器墊具有相同的結構和操作原理。每個(gè)墊子都有兩個(gè)導電板，它們由非導電的可壓縮隔板隔開(kāi)。這些墊子在24V DC下工作，并串聯(lián)在一起，以形成機器周?chē)ｋU區域的地面感應系統。通過(guò)墊的電路由控制單元監控，當區域空閑時(shí)，控制單元向機器控制電路提供信號。當踏上任何墊子時(shí)，導電板接觸，電路中的電阻下降。
這由關(guān)閉機器的控制單元監控。將檢測到墊、接線(xiàn)或控制單元中的任何單個(gè)電氣故障，并且控制單元輸出將進(jìn)入安全（OFF）狀態(tài)。模制乙烯基傳感器墊密封至IP 67.440F-C28013控制單元。該單元包括一個(gè)八通道傳感墊系統。當踩下任何墊子時(shí)，控制單元將關(guān)閉機器，并在CHANNEL FAULT STATUS（信道故障狀態(tài)）顯示屏上顯示正在操作的墊子。有兩種操作模式：手動(dòng)復位和自動(dòng)復位。在手動(dòng)復位模式下，輸出“ON”信號只能在移除驅動(dòng)力并復位后恢復。手動(dòng)復位通過(guò)按下和釋放蓋上安裝的控制單元復位按鈕或遠程安裝的按鈕來(lái)實(shí)現。在通電或斷電后以及隨后恢復電源后，輸出將“關(guān)閉”，直到收到復位信號，即使墊子未啟動(dòng)。在自動(dòng)復位模式下，僅通過(guò)移除驅動(dòng)力來(lái)實(shí)現輸出“ON”信號。對于這兩種模式，在啟動(dòng)墊子后，安全觸點(diǎn)將始終處于“OFF”（斷開(kāi)）狀態(tài)。第5節將更詳細地介紹模式選擇。各個(gè)傳感器墊通過(guò)4根電線(xiàn)相互連接并連接到控制單元?？刂茊卧哂薪徊姹O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。
Section 1 - Storage and Handling 1.1 Storage controls and pad sensors shall be stored in a temperature range of - 40 ° C to+70 ° C. Cushion sensors should be stored vertically. 1.2 The handling and transportation control devices and pad sensors shall be transported within the temperature range of - 40 ° C to+70 ° C. The original packaging or similar packaging shall be used, and if necessary, it shall be reinforced to prevent damage and bending. Always open the package carefully to avoid being damaged by knives, etc. When the sensor pad moves in place, do not pull or lift the sensor through its connecting wire. For larger sensor pads, two people are required to lift safely and prevent damage to the sensor pads due to excessive bending. 4 Section 2 - System Description The system consists of one or more interconnected pressure sensitive pads and a control unit. There is no "dead zone" in the detection area. The single sensor pad has rectangular standard size and special cutting shape. The maximum size is the maximum standard pad. All sensor pads have the same structure and operating principle. Each cushion has two conductive plates, which are separated by non-conductive compressible partitions. These pads work at 24V DC and are connected in series to form a ground sensing system in the hazardous area around the machine. The circuit through the pad is monitored by the control unit, which provides signals to the machine control circuit when the area is free. When stepping on any mat, the conductive plate contacts and the resistance in the circuit decreases.
This is monitored by the control unit that shuts down the machine. Any single electrical fault in the pad, wiring or control unit will be detected, and the control unit output will enter the OFF state. Molded vinyl sensor gasket seals to IP 67.440F-C28013 control unit. The unit includes an eight channel sensing pad system. When any mat is depressed, the control unit shuts down the machine and displays the mat being operated on the CHANNEL FAULT STATUS display. There are two operation modes: manual reset and automatic reset. In the manual reset mode, the output "ON" signal can only be restored after the driving force is removed and reset. 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.
