绞车有三种不同的操作模式

动增加”和“手动减小”按扭来调整皮带的张力。
通过按“手动启动”按
扭来启动绞车,给绞车电机通电。
HDW的PLC来控制所有动作的顺序并监测系统的任何故障和异
常。
此时就可以同过“手动增加”按扭或“手动减小”按扭来调节皮带的张力了。
当张力大于100KN
时,“手动增加”按扭将失效。
通过按人工停止按扭绞车将停机。
AutomaticMode:

在自动模式下HDW的PLC通过张力传感器的反馈来调节皮带的张力。
HDV的
PLC在程序中读
取启动和运转时的张力设定值(通常分别为100KN和70KN)。
当皮带机启动器发出信号后绞车电
动机通电。
这通常在胶带机启动信号发出5秒之后。
2秒钟后离合器和控制器
电磁阀开始激活。
绞
车控制器调整张力到启动值。
当张力在启动值的偏差5KN的范围内持续2秒
钟,张力符合的信号
反馈给皮带机启动器,然后皮带机启动器启动主驱动电机。
250秒后,张力从启动值降到运行值。
ReelingMode:
卷带模式
Inreelingmodethetensionisadjustedtothelowsetpointreelingtension(nominally5kN)bytheHDW.Thisprovidesaconstantlowtensionsuitableforreelingbeltduringamaingatebeltretraction.ThewinchmotormustbestartedbypressingtheManualStartpushbutton,afterwhichthetensionisautomaticallyadjustedto5kN.ThewinchisstoppedbypressingtheStoppushbutton.
通过转换控制面板上的转换开关来选择卷带模式。
在卷带模式下,HDV的PLC
将皮带的张力调节
到卷带张力(通常为5KN)。
这给卷带的时候提供了一个持续的合适的低张紧力。
这种模式下绞车
电机是通过手动启动按扭来启动的,当通过HDW的PLC控制张力到5KN时,绞
车也需要通过手
动按扭来停机。

当系统张力在预设定的时间内维持设定张力范围内,绞车自动停车,使得胶带张力不需要补偿时,绞车保持
怠速。
胶带张力显示使得操作者观察轿车运行。
但是电机及驱动系统不动作。
当绞车进入备用模式时,可持
续监测胶带张力,如果胶带张力超出范围,重新动作。
重新动作时间不超过3
秒,以提高或减低张力。

维持3秒,绞车将停车。
如果在维持2秒张力超过5KN绞车将动作。
