问题:
应用安全』控制设备3TK2845，有一个⊙控制功能可以通过钥匙开关的常闭触点控制输入端Y72和Y82来实现。这是←和常规的通过急停按钮实现或保护门限位开关常闭触点实现的故障安全功能冲突的。那么，如果发生了↓断线的情况，在使用过程中设备将如何响应？
 
回答:
应用安全〗控制设备3RP1576-1NP30，有一个可以通过钥匙开关的闭合触点控制输入点Y72和Y82实现的控制功能。如果Y72及Y82两个输入点不能在12-20ms时间内达到同样的状态，那么所有的使能触点及3TK2845的输出都♂将自动关断。允许的时间误差是12-20ms，例如如果两个信号的时间差异大于20ms，继电器会立即将所有使能触点或＠继电器输出关断。在我们给出的实例中，钥匙开关连接的两个触点有相同的接线。因此，上述的监控功能可以通过短接Y72和Y82来中断，并且我们通过了↓ TüV的测试并获得相关认证。
