求翻译：当505E完成启动（三者中任意一种）并且满足相关的许可条件后，抽汽控制可以自动或手动投入运行。典型地，在抽汽控制投入之前，透平将转速/负荷控制在额定转速设定值并且高于最小负荷值。在启动后，高压和低压阀位限制器通常应全部打开。如果高压阀位限制器没有完全开启，它将作为一个转速/负荷限制器，同时也将妨碍自动调节器的运行是什么意思？

When 505E complete start (one of the three) and meet the relevant license conditions, steam control can be automatically or manually and put into operation. Typically, prior to extraction control inputs, turbine rated speed setpoint speed/load control and higher than the minimum load. After startup, high voltage and typically low-voltage valve position limit is fully open. If a high pressure valve position limit is not fully open, it will serve as a speed/load limiters, also would prevent automatic regulator operating
