在抱闸调整工作开始前，确保不存在任何的电能和机械能。确保抱闸轮毂和闸瓦不要沾上油脂和润滑剂。制动器开闸行程的调整：参考松开螺母3和螺钉4。顶杆4必须彻底离开抱闸铁芯的螺钉14。顺时针旋转螺钉4至与顶杆螺钉14刚好接触，然后继续顺时针旋转1圈（螺距2mm），推动制动器顶杆，使衔铁向内移动2mm。相同方法调整另一侧。给制动器通电，此时制动器顶杆从内侧向外移动的最大行程为4mm。（若行程小，可顺时针旋转顶杆螺钉4增大行程；反之，逆时针减小行程）。

Summary: fire-resistant cable refers to the cable which can keep safe running for a certain time under the condition of flame burning. China's national standard GB12666.6 IEC331 (e) will fire test points A, B two levels, A grade flame temperature of 950 ~ 1000 ℃, the duration for fire, 90 min, class B flame temperature of 750 ~ 800 ℃, for fire duration 90 min, during the whole test, the sample should be under the rated voltage value of the product. Fire-resistant cable is widely used in high-rise buildings, subway, underground street, large power stations and the important industrial and mining enterprises and other related to fire security and its lifesaving, for example, fire fighting e and emergency light guide emergency facilities such as power supply circuit and control circuit. Purpose: fireproof cables are widely used in high-rise buildings, subway, underground street, large power stations and the important industrial and mining enterprises and other related to fire security and its lifesaving, for example, fire fighting e and emergency light guide emergency facilities such as power supply circuit and control circuit.

下图的拨码开关将显示的数字转换为4位二进制数。plc用12个数字量输入点读取的是3位BCD码，它的值为2#，即十六进制数16#829。BCD码没有单独的表示方法，而是借用了十六进制的表示方法，因此二者很容易混淆。下图是S7-300/400的BCD码和整数的相互转换指令，可以看到在指令中BCD码均用十六进制的形式表示。在程序中，怎么知道一个数字是BCD码还是十六进制数呢？1）看数据的来源和用途。
在使用RS485接口时，对于特定的传输线路，从RS485接口到负载其数据信号传输所允许的最大电缆长度与信号传输的波特率成反比，这个长度数据主要是受信号失真及噪声等影响所影响。理论上，通信速率在100Kbps及以下时，RS485的最长传输距离可达1200米，但在实际应用中传输的距离也因芯片及电缆的传输特性而所差异。
