MVME172-263A工業(yè)備件
遵守電氣安全預(yù)防措施。8.5.1癥狀–如果墊子上沒有任何東西，并且遵循了正確的重置程序，則無法啟動(dòng)機(jī)器。1.如果墊子控制單元上的MACHINE ENABLED LED（機(jī)器啟用LED）亮起，則機(jī)器或墊子系統(tǒng)外部的控制系統(tǒng)可能存在故障。檢查控制單元安全輸出線路中的外部保險(xiǎn)絲，必要時(shí)予以更換。確保使用正確的保險(xiǎn)絲值（最大2A）。將更換記錄在檢查日志中。如果保險(xiǎn)絲立即熔斷或需要提前更換，則墊控制單元的安全輸出和機(jī)器的最終控制元件（接觸器）之間的機(jī)器控制電路可能存在故障。2.如果墊子控制單元上的MACHINE ENABLED LED（機(jī)器啟用LED）熄滅，請采取以下措施：檢查POWER LED（電源LED）是否點(diǎn)亮。如果不是，請檢查墊子控制單元的電源。檢查電源是否連接到適當(dāng)?shù)亩俗?。檢查控制單元中的主保險(xiǎn)絲和輔助保險(xiǎn)絲，必要時(shí)予以更換。確保一次保險(xiǎn)絲和二次保險(xiǎn)絲使用正確的保險(xiǎn)絲值（500mA防浪涌）。將更換記錄在檢查日志中。如果保險(xiǎn)絲立即熔斷或需要提前更換，請聯(lián)系供應(yīng)商。3.如果墊控制單元上的MACHINE ENABLED LED（機(jī)器啟用LED）熄滅，POWER LED（電源LED）點(diǎn)亮。
在帶有接觸器監(jiān)控的雙通道系統(tǒng)上，如果外部安全輸出保險(xiǎn)絲未熔斷，則控制單元外部仍可能存在故障。任一接線通道中的單一故障將導(dǎo)致墊子控制單元鎖定安全輸出，直到故障得到糾正并重置控制單元。檢查系統(tǒng)中的所有連接導(dǎo)線是否正確配置且未損壞，兩個(gè)接觸器是否正常工作。排除所有故障，如果處于手動(dòng)復(fù)位模式，則按下并釋放控制單元復(fù)位按鈕。4.如果問題未得到解決，請聯(lián)系供應(yīng)商。38 8.5.2癥狀–機(jī)器無法停止或可以在墊子上啟動(dòng)。不允許使用機(jī)器1。如果墊子上有機(jī)器，墊子控制單元上的機(jī)器啟用LED是否點(diǎn)亮？2.如果MACHINE ENABLED LED（機(jī)器啟用LED）未亮起，則機(jī)器或其控制系統(tǒng)在墊系統(tǒng)外部可能存在故障。–在排除和測試故障之前，不得使用機(jī)器。3.如果機(jī)器啟用LED亮起。-不允許使用機(jī)器，并立即聯(lián)系供應(yīng)商。8.5.3癥狀–機(jī)器在傳感器墊上不存在的情況下意外停止，但可以在踩下墊后重新啟動(dòng)（并在手動(dòng)重置模式下重置）。1.檢查所有指示燈是否正常工作。如果是這樣的話，問題很可能是由某個(gè)值和持續(xù)時(shí)間的供電下降引起的。
Observe electrical safety precautions. 8.5.1 Symptoms – If nothing is on the mat and the correct reset procedure is followed, the machine cannot be started. 1. If the MACHINE ENABLED LED on the mat control unit lights up, there may be a problem with the control system outside the machine or mat system. Check the external fuse in the safety output circuit of the control unit and replace it if necessary. Make sure to use the correct fuse value (max. 2A). Record the replacement in the inspection log. If the fuse blows immediately or needs to be replaced in advance, there may be a problem with the machine control circuit between the safety output of the pad control unit and the final control element (contactor) of the machine. 2. If the MACHINE ENABLED LED on the mat control unit is off, take the following measures: Check whether the POWER LED is on. If not, check the power supply of the mat control unit. Check that the power supply is connected to the appropriate terminal. Check the main and auxiliary fuses in the control module and replace them if necessary. Ensure that the primary fuse and secondary fuse use the correct fuse value (500mA anti surge). Record the replacement in the inspection log. If the fuse blows immediately or needs to be replaced in advance, please contact the supplier. 3. If the MACHINE ENABLED LED on the pad control unit is off, the POWER LED is on.
On a dual channel system with contactor monitoring, if the external safety output fuse is not blown, there may still be faults outside the control unit. A single fault in any wiring channel will cause the mat control unit to lock the safety output until the fault is corrected and the control unit is reset. Check whether all connecting wires in the system are correctly configured and undamaged, and whether the two contactors work normally. Eliminate all faults. If it is in the manual reset mode, press and release the control unit reset button. 4. If the problem is not solved, please contact the supplier. 38 8.5.2 Symptoms - The machine cannot be stopped or can be started on the mat. Machine 1 is not allowed. If there is a machine on the mat, does the machine enable LED on the mat control unit illuminate? 2. If the MACHINE ENABLED LED is not lit, the machine or its control system may have a fault outside the cushion system. – Do not use the machine until the problem has been corrected and tested. 3. If the machine enable LED lights up- Do not use the machine and contact the supplier immediately. 8.5.3 Symptoms - The machine stops unexpectedly when the sensor pad is not present, but can be restarted after the pad is depressed (and reset in manual reset mode). 1. Check whether all indicators work normally. If so, the problem is likely to be caused by a drop in power supply for a certain value and duration.
