操作模式

單通道操作：輸入接線按照vde0113-1及en60204-1標(biāo)準(zhǔn)執(zhí)行，輸入電路中回路冗余輸入。接地故障將會(huì)在急停回路中被檢測(cè)。

雙通道操作：輸入回路中存在冗余重復(fù)輸入。急?；芈分械慕拥毓收霞凹蓖０粹o相鄰成對(duì)觸點(diǎn)間的短路故障都將被檢測(cè)。

自動(dòng)復(fù)位：當(dāng)輸入回路閉合時(shí)裝置立即被激活。
•automaticreset:unitisactiveassoonas
theinputcircuitisclosed.
帶監(jiān)視的手動(dòng)復(fù)位：裝置僅在此種情況下被激活---在輸入回路閉合前復(fù)位回路須斷開(kāi)，并且在輸入回路閉合且延時(shí)時(shí)間到以后復(fù)位回路再次閉合。這樣可以消除因復(fù)位按鈕越控（指早于輸入回路閉合，若此時(shí)輸入回路閉合后立即斷開(kāi)，會(huì)發(fā)生自動(dòng)復(fù)位，如果此時(shí)輸入回路又再次閉合，則會(huì)發(fā)生安全繼電器反復(fù)通斷，會(huì)產(chǎn)生不可預(yù)料的后果。筆者認(rèn)為類(lèi)似于電力二次回路的防跳）而觸發(fā)自動(dòng)復(fù)位的可能。

為確保作為檢測(cè)輸入回路間短路的功能沒(méi)有失效，pilz在后的控制檢查中會(huì)給予測(cè)試。但安裝完畢后仍有可能進(jìn)行測(cè)試。步驟如下：

3、裝置的保險(xiǎn)必定被trigger，并且同時(shí)輸出回路切斷。電纜在大允許長(zhǎng)度范圍內(nèi)時(shí)，能夠延遲保險(xiǎn)trigger達(dá)2分鐘。
