 二是通过输入信号之间的联锁，这种方法工作量大，考虑要***，否则也会出现输入信号相互干扰，起反作用。所以当设计完成后，一定要进行模拟试验，杜绝误操作的出现。图2是一个简化的梯形图，图中：0003为1号低压泵起动按钮；HR400为1号主机停止24h后标志；HR401为2号主机停止24h后标志；0005为2号低压泵起动按钮。实际上的相互制约的关系很复杂，此图只是说明一下如何避免误操作。图2的工作原理为1号或2号低压泵任意一台工作，并互为备用，保证有一台在工作。1号或2号低压泵停止按钮的常闭接点（0004，0006）互为连锁，当操作人员误按停机按钮0004(0006)时，程序会自动起动另一台低压泵（1号或2号低压泵），从而避免低压泵停机严重事故的发生。HR100为低压泵起动标志，常开（闭）接点广泛串联到各个相关回路中，尤其是串联到高压泵控制回路中，保证在低压泵未起动的前提下，起动高压泵无效，从而避免对高压泵的误操作。
