Examine the Winch for structural cracks, bends, damage, frayed or kinked cable, and any other conditions that may affect the safe operation of the winch.∙Do not use the winch even if minor damage appears. Keep cable straight to avoid kinking it. A kink permanently weakens the cable, even after it is straightened out. Kinked cable can fail suddenly and must not be used.∙Do not use a recovery strap while winching. They are designed to stretch and can suddenly whip back towards the operator during a winching operation.∙The winch is designed to be attached to a mounting plate or structure capable of supporting the load that is intended to pull (lift). Mounting location and hardware must support your Winch and load.∙For maximum strength and safety, this winch should be mounted with three 3/8" or M10 bolts, washers, and lock washers (not included, sold separately). The bolt should attach the winch to the mounting structure utilizing the outside rear holes or slots. The third bolt should be insertedthrough the winch frame and mounting structure in a manner to utilize the foremost remaining frame slot (hole).∙Select a winch line with breaking strength at least 1-1/2 times the winch rating and a hook 1-1/2 times stronger than the line.∙CABLE REPLACEMENT: Use extreme care when replacing cable, it is secured under tension by the cable clamp, and may spring back forcefully.1) Place pawl in reel out position. Reel the old cable all the way out by turning handlecounterclockwise.2) Loosen the nut and remove the old cable from underneath the cable clamp.3) Remove the old cable.4) Route new cable end over bushing and through the hole to the outside of the drum.5) Install the cable under the cable clamp.6) Tighten the nut securely.7) Placepawl in reel in position, then reel the new cable onto drum by turning the handle clockwise,being careful not to allow kinking.∙Test winch for proper operation.∙If nylon strap is used, it should have a loop sewn in one end and be attached using a 3/8" x 3" or1 /4" x 2-3/4" long bolt and locknut. Use a locknut, not a nut, and lockwasher.

5.3.2.1 过载保护保护原理：本装置用数字方法建立电动机的发热模型，在各种运行工况下，对电动机提供准确的过热保护。
考虑到正、负序电流的热效应不同，在发热模型中采用热等效电流Ieq ，其表达式为：式中，K1=0.25(电动机起动时间内)K1=1 (电动机起动结束后)K2=6 (负序发热系数)I1：正序电流I2：负序电流K1随电动机起动过程变化,为的是躲过电动机的起动电流，K2用于改变负序电流在发热模型中的热效应，由于负序电流在转子中的热效应比正序电流高很多，比例上等于在两倍系统频率下转子交流阻抗对直流阻抗之比。
根据理论和经验，本装置取 K2=6。
电动机的积累热容量∑Θ为：式中，t ∆：积累热容量计算间隔，本装置取t ∆=0.01s 。
电动机的跳闸过热量T Θ为： 式中，fr T ：电动机的发热时间常数fr e T T I .2=Θ当∑Θ?T Θ时，过载保护动作。
∑Θ=0表示电动机已达到热平衡，无积累过热量。
电动机在冷态（即初始过热量∑Θ=0）的情况下，过热保护的动作时间为：当电动机停运，电动机积累的过热量将逐步衰减，本装置按指数规律衰减过热量，散热时间常数Tsr 一般为4倍的电动机发热时间常数Tfr ，即认为Tsr 时间后，电动机又达到热平衡。
电机过载保护的机组动作时间(单位：s)整定发热时间常数可以获得更多的动作曲线。
过载保护设置：保护原理：堵转保护是防止电机出现严重运转堵塞或因为电机超负荷运行而损坏电机。
堵转保护分为两个区间，起动过程中和起动完成后。
在起动过程中由于起动电流较大，为了防止误判需要合理设置起动中延时。
起动完成后如果发生堵转故障，此时对电机的危害最大，因为电机可能已经达到热平衡，没有多少热容量剩余，更容易烧毁电机，要求堵转保护能够迅速动作，所以要合理设置起动后延时。
当最大相电流大于堵转保护定值时，并保持时间超过堵转保护延时时间，堵转保护动作。
堵转保护设置界面：地时，过IA+IB+IC=I0原理，由装置内部计算出零序电流I0。
也可以通过外接零序互感器来采集零序电流。
零序电流大于接地保护定值，并且持续时间超过接地保护延时时间，接地保护动作。
当接地保护投入后，在闭锁时间后自动开启。
接地保护设置界面：接地保护可以选择跳闸方式为跳断路器，当保护条件满足时，装置将从可编程输出2输出一个跳闸脉冲给断路器。
这时需要将可编程输出2配置为“跳断路器”。
5.3.2.4 过流保护保护原理：本装置提供过流保护功能，当最大相电流超过过流保护定值，并且持续时间超过设定的保护延时后，过流保护动作。
过流保护在起动时间内闭锁，起动完成后自动开启。
过流保护设置界面:倍。
保护原理：低电压保护主要有两个方面的功效：一是当发生低电压故障时，电机转矩不足，长期运行会导致电机的烧毁，因此需要在发生低电压故障时，及时停止电机运行；另外一方面当系统发生低电压时，通过切断不重要负荷，有效的保证了重要负荷的连续工作，维持了系统的稳定性。
两个线电压同时大于额定电压的25%且低于定值，并且持续时间超过低电压保护延时时间，低电压保护动作。
当低压保护投入后，在电机起动时刻自动开启。
低压保护设置界面：保护原理：负序电流在转子中的热效应比正序电流高很多，当相序接反后，负序电流明显增大，正序电流明显减小。
当负序电流大于正序电流的4倍时，并且持续时间超过相序保护延时时间，相序保护动作。
当相序保护投入，在电机起动时刻自动开启。
相序保护设置界面：5.3.2.7式中：Imax ：偏离平均值最大的相电流Iavr ：三相平均电流Ie:电机的额定电流如果不平衡保护投入，在电机起动时刻自动开启。
不平衡保护设置界面：机。
两个线电压同时大于过压保护整定值时，并且持续时间超过过电压保护延时时间，过压保护动作。
当过压保护投入后，在电机起动时刻自动开启。
过压保护设置界面：保护原理：电机缺相时导致严重的转子发热，从而烧毁电机。
它的灵敏度高于过载保护，是在前期发现导致电机烧毁的故障，有效保护电机。
当一相电流小于10%的额定电流，而另外两项大于20%的额定电流，并且持续时间超过缺相保护延时时间，缺相保护动作。
当缺相保护投入后，在电机起动时刻自动开启。
设置界面：当漏电流大于漏电保护整定值，并且持续时间超过漏电保护延时时间，漏电保护动作。
当漏电保护投入后，在电机起动完成后自动开启。
