HITACHI LPA245A電源模塊
1.產(chǎn) 品 詳 情 資 料：
為了執(zhí)行運(yùn)行SIL3應(yīng)用程序的HITACHI LPA245A的熱插拔，在熱插拔數(shù)字輸入（I3）打開(kāi)之前，必須通過(guò)鍵開(kāi)關(guān)打開(kāi)訪問(wèn)啟用數(shù)字輸入（I2）。這是通過(guò)將物理按鈕連接到數(shù)字輸入來(lái)執(zhí)行的。系統(tǒng)等待確認(rèn)30分鐘，如果未接收到確認(rèn)，則插入的HITACHI LPA245A將關(guān)閉。為了恢復(fù)，需要啟動(dòng)新的熱插拔，即HITACHI LPA245A必須被移除并再次插入。HITACHI LPA245A的同步包括：1。確保HITACHI LPA245A之間的同步鏈路已就位，也就是說(shuō)，封閉的TK852V010電纜已分別正確連接到兩個(gè)SM鏈路連接器中。2.將HITACHI LPA245A插入其位置。3.當(dāng)HITACHI LPA245A啟動(dòng)時(shí)，同步LED閃爍，隨后它繼續(xù)閃爍，并按順序閃爍3次和暫停。4.按下按鈕（在已經(jīng)運(yùn)行的安全模塊上的數(shù)字輸入3上創(chuàng)建一個(gè)邊緣），一旦它開(kāi)始以3次閃爍和一個(gè)暫停序列重復(fù)閃爍。5.同步指示燈閃爍得更快，直到同步完成。6.模塊同步時(shí)，同步指示燈變?yōu)辄S色。
For performing the hot swap of HITACHI LPA245A running a SIL3 application, the Access enable digital input (I2) must be turned ON through the key switch before the Hot-insert digital input (I3) is turned ON.This is performed by connecting a physical push-button to the digital input. The system waits for 30 minutes for the acknowledgement, if acknowledgement is not received the inserted HITACHI LPA245A will shut down. To recover, a new hot insert needs to be initiated i.e. the HITACHI LPA245A has to be removed and inserted again. Synchronization of the HITACHI LPA245A includes: 1. Make sure that the synchronization link between the HITACHI LPA245As is in place, that is, the enclosed TK852V010 cable is properly connected into both SM Link connectors respectively. 2. Insert the HITACHI LPA245A in its position. 3. When the HITACHI LPA245A starts the synchronization LED flashes, and later it continues to blink with 3 blinks and a pause in a sequence. 4. Push the button (create an edge on digital input 3 on the already running Safety Module), once it starts blinking repeatedly with 3 blinks and a pause sequence. 5. The Sync LED flashes faster until the synchronization is complete. 6. The Sync LED turns yellow when the module is synchronized.
