按下重置按鈕：機器啟用的LED在墊子運行時(shí)亮起：機器啟用LED熄滅墊：機器啟用發(fā)光二極管仍熄滅按下重置按鈕，機器啟用LED亮起在故障情況下，機器啟用的燈熄滅，在故障排除之前不允許重置。在故障狀態(tài)下，如果存在墊子故障，一個(gè)或多個(gè)墊子狀態(tài)LED將點(diǎn)亮。在開(kāi)路或短路情況下，LED將亮起紅色。如果存在故障，且MAT STATUS LED均未亮起，則說(shuō)明控制單元故障。6.5檢查安全功能6.5.1單通道系統（參見(jiàn)圖15和17第5節）模擬正常操作。站在墊子上啟動(dòng)墊子，并檢查主接觸器是否立即脫落。檢查任何其他與安全相關(guān)的停止功能，如制動(dòng)器、離合器接觸器是否按預期運行。6.5.2雙通道系統（見(jiàn)圖16和18第5節）1.模擬正常操作。站在墊子上啟動(dòng)墊子，并立即檢查兩個(gè)最終接觸器是否脫落。檢查任何其他與安全相關(guān)的停止功能，如制動(dòng)器/離合器接觸器是否按預期運行。
2.隔離電源，然后通過(guò)將端子塊6處的端子13和14短路來(lái)安裝臨時(shí)故障（圖26或27）。3.恢復電源并啟動(dòng)傳感器墊，并檢查其中一個(gè)最終接觸器是否立即斷開(kāi)，以及與該通道相關(guān)的任何其他停止功能是否按預期運行。4.檢查控制單元不會(huì )復位5.隔離電源并排除臨時(shí)故障?；謴碗娫床z查墊子系統是否正常工作。采取相同的電氣安全預防措施，在端子塊6處的端子23和24之間臨時(shí)短路，重復測試（圖26或27）。6.再次檢查控制單元不會(huì )復位7.排除臨時(shí)故障，檢查墊系統是否正常工作。35 6.5.3所有系統類(lèi)型1.進(jìn)行所需的任何其他測試，以確認安全相關(guān)控制系統符合EN 954-1規定的類(lèi)別要求，并按預期工作。2.檢查與受墊系統安裝影響的機器電路相關(guān)的任何其他安全功能。這些測試應有現有程序。3.在電源處隔離機器電源。4.重新連接機器控制系統提供的任何自動(dòng)復位功能。5.將機器原動(dòng)機重新連接至最終接觸器。6.固定所有蓋子和門(mén)。6.6功能檢查恢復機器電源。檢查：-1。在重置墊子控制單元之前，機器無(wú)法開(kāi)始操作。
Press the reset button: the machine enabled LED lights up when the mat is running: the machine enabled LED goes out Pad: the machine enabled LED is still off Press the reset button, the machine enabled LED lights up In case of a fault, the machine enabled lamp goes out, and resetting is not allowed until the fault is eliminated. In the fault state, if there is a mat fault, one or more mat status LEDs will illuminate. In case of open circuit or short circuit, the LED will light red. If there is a fault and the MAT STATUS LED is not lit, the control unit is faulty. 6.5 Checking safety functions 6.5.1 Single channel system (see Figure 15 and Section 5 of 17) simulates normal operation. Stand on the mat and start the mat, and check whether the main contactor falls off immediately. Check whether any other safety related stop functions, such as brake and clutch contactor operate as expected. 6.5.2 Dual channel system (see Figure 16 and 18, Section 5) 1. Simulate normal operation. Stand on the mat and start the mat, and immediately check whether the two final contactors fall off. Check that any other safety related stop functions, such as brake/clutch contactors, operate as expected.
2. Isolate the power supply, and then install a temporary fault by shorting terminals 13 and 14 at terminal block 6 (Figure 26 or 27). 3. Restore the power supply and start the sensor pad, and check that one of the final contactors is immediately disconnected, and that any other stop functions associated with this channel operate as expected. 4. Check that the control unit will not reset 5. Isolate the power supply and eliminate the temporary fault. Restore the power supply and check whether the mat subsystem works normally. Take the same electrical safety precautions, temporarily short circuit between terminals 23 and 24 at terminal block 6, and repeat the test (Figure 26 or 27). 6. Check again that the control unit will not reset 7. Remove the temporary fault and check whether the cushion system works normally. 35 6.5.3 All system types 1. Carry out any other tests required to confirm that the safety related control system conforms to the category requirements specified in EN 954-1 and works as expected. 2. Check any other safety functions related to the machine circuit affected by the installation of the mat system. These tests should have existing procedures. 3. Isolate the machine power at the power supply. 4. Reconnect any automatic reset functions provided by the machine control system. 5. Reconnect the machine prime mover to the final contactor. 6. Secure all covers and doors. 6.6 Function check to restore the machine power. Check: - 1. The machine cannot start operation until the mat control unit is reset.
