MOOG D136-001-008運動控制器防止電氣故障在系統(tǒng)部件故障的情況下，設(shè)計應(yīng)為可接受的“故障安全”設(shè)計，其中故障不會造成安全危險，如失控或緊急停止電路失效。MOOG D136-001-008緊急停機和其他安全電路應(yīng)由硬接線部件組成，這些部件易于以無害的方式發(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、常閉緊急停止按鈕開關(guān)和聯(lián)鎖裝置控制機電主控制繼電器。該繼電器應(yīng)直接禁用電機啟動器、PLC輸出電路等。這種類型的電路往往會出現(xiàn)故障“斷開”，從而禁用設(shè)備。例如，如果導(dǎo)線斷開或觸點磨損，則電路斷開，MCR下降。如果固態(tài)設(shè)備發(fā)生故障，它們往往會發(fā)生故障“短路”，MOOG D136-001-008在PLC輸出電路的情況下，這會導(dǎo)致受控設(shè)備打開或保持打開
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
