MOOG D136-001-008運(yùn)動(dòng)控制器防止電氣故障在系統(tǒng)部件故障的情況下，設(shè)計(jì)應(yīng)為可接受的“故障安全”設(shè)計(jì)，其中故障不會(huì)造成安全危險(xiǎn)，如失控或緊急停止電路失效。MOOG D136-001-008緊急停機(jī)和其他安全電路應(yīng)由硬接線(xiàn)部件組成，這些部件易于以無(wú)害的方式發(fā)生故障。例如，在主控制繼電器（MCR）電路中，MOOG D136-001-008使用串聯(lián)接線(xiàn)、常閉緊急停止按鈕開(kāi)關(guān)和聯(lián)鎖裝置控制機(jī)電主控制繼電器。該繼電器應(yīng)直接禁用電機(jī)啟動(dòng)器、PLC輸出電路等。這種類(lèi)型的電路往往會(huì)出現(xiàn)故障“斷開(kāi)”，從而禁用設(shè)備。例如，如果導(dǎo)線(xiàn)斷開(kāi)或觸點(diǎn)磨損，則電路斷開(kāi)，MCR下降。如果固態(tài)設(shè)備發(fā)生故障，它們往往會(huì)發(fā)生故障“短路”，MOOG D136-001-008在PLC輸出電路的情況下，這會(huì)導(dǎo)致受控設(shè)備打開(kāi)或保持打開(kāi)
Protection From Electrical Failure In the event of a system component failure, the design should be an acceptable “fail-safe” one in which the failure does not cause a safety hazard such as a runaway condition or a disabling of emergency stop circuits. Emergency stop and other safety circuits should consist of hard-wired components that tend to fail in a harmless manner.MOOG D136-001-008For example, in a Master Control Relay (MCR) circuit, use series-wired, normally closed Emergency Stop pushbutton switches and interlocks to control an electro-mechanical Master Control Relay (see next figure). This relay should directly disable motor starters, PLC output circuits, etc. This type of circuit tends to fail “open,” which disables the equipment. For example, if a wire breaks or a contact wears out, the circuit opens and the MCR drops out. If solid state devices fail, they tend to fail “shorted,” which in the case of PLC output circuits would cause the controlled device to turn on or stay onMOOG D136-001-008
